Is it true that tomatoes can be grown in drylands? With the cultivation technology of dryland tomato, there is no need to worry about the dry weather again. Tomato has been deeply loved by the Chinese people, so its corresponding cultivation technology is also constantly improving. Today, Xiaobian brings everyone to learn about the cultivation technology of dryland tomato.
I. Preparation for high-yield cultivation techniques of tomato in dry land
1, the choice of variety
Compared with ordinary tomatoes, dryland tomatoes have obvious advantages in planting, and the production effect is also obvious compared with ordinary tomatoes. However, before the relevant planters work, if there is no clear confirmation of the varieties of dryland tomatoes, which causes some common tomato varieties to be mixed into the tomato varieties in the dryland, it will seriously affect the use of subsequent high-yield cultivation techniques and at the same time reduce indirectly. Yield and quality of dryland tomatoes. Therefore, before carrying out the work, the relevant planters must confirm whether the varieties of dryland tomatoes meet the standards, so that the production and quality of the dryland tomatoes can be guaranteed, and the high-yield cultivation techniques can be used smoothly. In addition, the relevant staff should carefully examine the quality of the problem and the dryland tomato varieties with disease roots to prevent such problematic seeds from appearing in other high-quality seeds, thus affecting the growth effect of high-quality varieties, giving cultivation work. Bringing obstacles.
2. Choice of land
In addition to focusing on the detection of tomato varieties, relevant staff should also strengthen the emphasis on land selection. Because dryland tomatoes have obvious thermophilic characteristics, when selecting land, we should pay attention to the following aspects: First, the staff should try to choose land with longer sunshine time, so that tomatoes can absorb sunlight to the maximum extent. In order to promote the growth of tomatoes. Second, we must choose a leeward land. If the tomato is often affected by the wind during the cultivation process, it will seriously affect the growth efficiency and quality of the tomato. If the protective measures are not taken, the yield of the tomato in the dryland will be greatly reduced. Therefore, it is necessary to pay attention to this aspect. Third, the staff should choose land that is easy to drain.
Because the tomato can not receive the influence of the water raft during the cultivation process, it must maintain a certain degree of dryness, otherwise it will affect the growth of the plant. Fourth, we should choose land with better soil fertility for planting. Before the relevant staff can carry out the work, it is also necessary to compare the soil fertility of multiple areas, and select the best quality land for tomato cultivation, so that the tomato can thrive in the soil with abundant soil, and at the same time, to a certain extent. The cost of saving fertilizers has a significant impact on the use of high-yield cultivation techniques. Fifth, before planting dryland tomatoes, the relevant staff should also know what the crops were before the land. If the previous land is planted with crops such as cucumbers or potatoes, then it is not suitable for growing dryland tomatoes, because the soil on which the crops are grown will be affected and the soil properties will be altered, causing damage to the tomatoes. If the land is planted with crops such as soybeans or millet, then you can plant tomatoes with peace of mind to provide convenience for the cultivation of tomatoes.
2. High-yield cultivation techniques and pest control in dryland tomato
1. Agricultural control measures
The growth and development period of tomato cultivation in dryland is the most important. At this time, it is the stage of high temperature and heavy rain. Pests and diseases are extremely easy to occur, and scientific means must be taken for prevention and control. Therefore, it is necessary to pay attention to the selection of tomato varieties to prevent the cultivation of pests that are prone to local pests and diseases; to carry out rotation according to scientific requirements on the dumplings, and to pay attention to soil disinfection and sterilization during the cultivation process.
2, biological control
There are many kinds of biological control methods, which come down to two aspects: on the one hand, through the way of biological agents, the growth of tomatoes is ensured by spraying of pesticides, for example, using plant-derived pesticides and biological-sourced pesticides for prevention and control; Prevention and control by the natural enemies of pests and diseases will reduce disaster losses and increase production efficiency.
3. Chemical control
In the prevention and control of pests and diseases, scientific methods of prevention are more effective than those of long-term sedimentation. However, in order to create a healthier green product, chemical control is only used as an auxiliary means of prevention. Once used, special attention should be paid to the dosage and pesticide selection. Because if there is improper selection or the dose of pesticide is not accurate enough, it will have more trouble. Take the pesticide dosage as an example. Once the pesticide dosage is insufficient, there is no way to achieve the predetermined effect. The pests and diseases may not be treated. On the contrary, if the pesticide dosage is too large, the pests and diseases are treated, but the pesticide residues on the fruits are caused. This leads to products that do not meet the standards for pollution-free products. Therefore, caution is required when using chemical control measures.
4, physical control
Physical control is based on the characteristics of tomato growth for more targeted prevention and control. In the actual farmland care process, pests can be reduced by timely removal of field weeds. At the same time, the soil can be disinfected and sterilized by the application of fertilizer, which can provide fertilizer for tomato growth, thereby improving the resistance and reducing pests and diseases. When pests and diseases occur, it is necessary to remove and destroy the plants with serious diseases to prevent the spread of pests and diseases.
As far as the use of high-yield cultivation techniques for dryland tomatoes is concerned, there has been a great improvement and breakthrough compared with the past. In recent years, the relevant national fruit and vegetable research departments have continuously strengthened the analysis and exploration of high-yield cultivation techniques for dryland tomatoes, and on the basis of the original technology, added some new technologies that are conducive to tomato growth and increased tomato yield, and the overall cultivation of tomato in dryland. And production has provided no small help. However, in order to make the cultivation level and cultivation quality of dryland tomatoes higher, it is necessary to pay attention to the prevention and control of the adverse factors affecting tomato growth, such as pests and diseases or environmental factors. At the same time, we can also learn from some excellent cultivation and cultivation cases to improve our own planting level, so as to provide reliable guarantee for the development of dryland tomato cultivation and cultivation industry.
The performance of the Baby Monitor Security Camera
The performance of the baby monitor is reflected by its built-in parameters and function combination. The following shows some properties that a high-quality and applicable baby monitor should have. The requirements for baby monitors in this part apply to all audio/video, digital/analog home baby monitors and wireless baby monitors, and are not changed due to the combination mode of the monitoring end and the control end.
The size shall be as small as possible: the small baby monitor (monitoring end and control end) is more convenient to install and carry in the family.Low power display: the baby monitor, especially the monitoring terminal, must work continuously for a long time. Once the product is low in power, it cannot remind parents to charge it in time. When the power continues to be consumed until it is exhausted, the control terminal will be unable to continue to receive any signal.
Voice trigger prompt: Voice trigger means that once the monitoring terminal detects the noise caused by the abnormal behavior of infants or children, it will be displayed at the control terminal through the noise prompt lamp.
The transmission signal frequency can be adjusted: the monitoring end of the baby monitor provides audio and video digital signals to the control end by transmitting wireless signals. If the transmission frequency of the monitoring end is not selected properly, it will produce electromagnetic interference with other household appliances, digital equipment, etc., which will affect the normal use of the product. Therefore, it is necessary to select a baby monitor that allows users to adjust the frequency of the transmitted signal at the monitoring end.
Adjustable volume: a friendly baby monitor will provide a volume selection knob or button at the control end. When parents are in an environment with loud background sound, they can hear the activity sound of babies and children by turning up the volume; When it is late at night or in a quiet environment, the low volume will not affect the normal rest of the people around you when you are answering normally.
VOX function: VOX is the abbreviation of sound activation start. The monitor with VOX function is in standby mode under normal conditions, and the screen and horn stop working, thus reducing the energy consumption of the product; Once it is detected that the monitored object has an abnormal sound exceeding the set standard, it will immediately flash its alarm lamp at the control terminal or directly light up the screen, and simultaneously play the audio and video information sent by the monitoring terminal.
Digital signals and analog signals: baby monitors using digital signals, such as Baohushen baby monitors, will have better transmission efficiency and provide users with clearer sound and picture quality; Moreover, digital signals can be encrypted to prevent being intercepted and interpreted by other receivers, effectively protecting users' family privacy; The electromagnetic signal interference of digital signal will be lower than that of analog signal, so as not to affect the normal work of other household appliances and equipment.
Monitoring end extension: The baby monitor with a friendly user experience should allow users to use one control end to manage the activities of several monitoring ends at the same time, especially in some families with multiple children. This good scalability not only reduces the trouble of carrying multiple control ends at the same time, but also reduces the objective additional expenses for these families.
Temperature display: some products will have the function of realizing the current indoor temperature, and even can set a critical value. Once the room temperature exceeds or falls below the critical value, an alarm signal will be sent. This is a very considerate function for temperature sensitive newborn children or sick children.
Intercom function: The high-end baby monitor allows parents to have a direct conversation with the baby (child) at one end of the monitoring end through the control end, so that children who are alone can provide psychological comfort. If children have any temporary needs or words, they can be known without bothering the guardian to run to the child.
Signal range: theoretically, the signal sent by the monitoring terminal can be received by the remote control terminal, which is more convenient for users to use the baby monitor flexibly. Now more and more families live in large family rooms, even multi-storey villas, and the baby monitor with strong signal receiving ability provides these families with a more convenient way of use. Parents no longer need to set the room beside the children in order to see and hear their children's every move. They can even take the control terminal to go out for a short walk!
Power supply mode: The baby monitor with built-in battery can automatically switch to the battery power supply mode when the external AC power supply is suddenly stopped, so that the user will not be affected to continue to monitor the child in the power failure environment.
