There are many vegetable farmers in China who are now planting water spinach, and there are many open-plant cultivation methods. There are also many greenhouse cultivation methods. Today we are going to talk about the planting points of greenhouse squid. As long as you figure out some planting points, you will definitely be able to improve the greenhouse. Yield and quality. In general, greenhouse vegetable cultivation can guarantee the annual supply and the morning market, but it is not acceptable if you do not have a certain cultivation technique. The cultivation of greenhouse vegetables requires special attention to the management of humidity, temperature and pests. Let's learn about the greenhouse. Three management points.
First, fertilizer management
The spinach is a vegetable that can be harvested many times. Generally, when picking, you can pick the young leaves first, and then wait for it to be harvested for a long time. The amount of fertilization in the water spinach should not be too much. During the growth of the seedlings, it can be drenched with thin human excrement, and the concentration should not be too high. When the spinach seedlings grow to three to four leaves, they can be mixed and fertilized with a certain compound fertilizer and nitrogen-containing elements. At the same time of fertilization, pay attention to the management of watering.
Second, the management of temperature and humidity
If the greenhouse is planted in a greenhouse, the temperature is relatively low and the humidity is relatively large. If the low-temperature environment lasts for a long time and the outside world has been rainy, then it is very good for the spinach that grows in a warm environment. Disadvantages. Therefore, at this stage, we must do a good job of keeping warm and cold, which is also the key point of cultivation at this stage.
Especially in the sowing and seedling stage, it is necessary to do a good job of temperature and humidity management. After sowing, we should seal the greenhouse in time to ensure that the temperature in the shed can be higher than 10 °C, which is good for its sprouting. If the temperature is too low, it will cause freezing damage, which is not conducive to seed germination and reduce the rate of emergence. However, if the outside is sunny and the temperature inside the membrane is too high, we need to carry out ventilation work. Because the temperature is too high, the plant will be diseased, which is not conducive to plant growth.
Third, pest control
If the temperature and humidity of the greenhouse are relatively high, the probability of occurrence of pests and diseases will increase, so we must promptly prevent pests and diseases. The measures that can be taken are timely ventilation, and if pests and diseases occur, it is best to use low-concentration drugs for spraying.
The above is all the content of today, you can see if you have any help, see if you usually pay attention to these issues, I hope to help the farmers!
