As the name suggests, pollution-free vegetables are health-standard vegetables. The residues of various harmful substances are within the safe range. As people's living standards are getting higher and higher, they are required for some things that are usually eaten. High up, so let's take a look at the promotion and application of this technology!
1 Development status of pollution-free vegetables
1.1 Meaning of pollution-free vegetables
As we all know, vegetables are important foods in people's daily life. With the continuous advancement of society, people's demand for vegetables continues to increase, and the pursuit of vegetable quality continues to grow. From the previous pursuit of food and clothing, it gradually changed into green and healthy. Pursuit, so the cultivation of pollution-free vegetables has received a high degree of attention.
Non-polluting vegetables are ecological foods that not only require the production environment to meet standards, but also ensure that the production process meets relevant standards. Therefore, when planting pollution-free vegetables, environmental factors need to be certified to ensure that the production process of pollution-free vegetables is reliably guaranteed, and the relevant operations can meet the standards to further ensure that pollution-free vegetables can be used as green food production quality.
1.2 Status of pollution-free vegetables
Although the advantages of pollution-free vegetables have been well known, there are still many concerns when farmers are planting pollution-free vegetables. The most important thing is that the cost of pollution-free vegetable cultivation techniques will be relatively high. The reason why there is a difference between pollution-free vegetables and general vegetables is that there is a difference in quality and safety, so the cost of pollution-free vegetable cultivation technology will be significantly higher than the traditional cultivation form. Although the cultivation techniques of pollution-free vegetables are relatively mature, they still need to be vigorously promoted. China has begun to pay attention to the promotion of pollution-free vegetables, and I believe that it will be better developed in the future.
2 Types of pollution-free vegetable cultivation techniques
2.1 Seed pretreatment technology
In order to better apply the technology of pollution-free vegetable cultivation, first of all, it is necessary to improve the seed treatment system. The most common methods at this stage are warm water soaking and low temperature refrigeration, and the relevant treatment measures are carried out through different types of washing. Secondly, when planting, ensure that the seedlings have better growth space and adequate nutrition. Through the use of seedling technology, seedlings have a better growth environment before seeding.
2.2 Pesticide treatment technology
It is necessary not only to comprehensively treat the seeds, but also to control the use of pesticides to prevent the effects of pests and weeds on the production of pollution-free vegetables. To increase the importance of prevention, it is necessary to establish an effective management framework, and at the same time use pesticides correctly, enhance the level of control, and fundamentally limit the growth of pests. In addition, pesticides must be selected in accordance with national standards to reduce pesticide residues and improve the efficiency of pesticide use. Planters need to develop a management system based on actual conditions and the living habits of pests. Only in this way can we ensure the scientific and effective use of pesticides.
2.3 Irrigation technology
In order to meet the water demand for pollution-free vegetable cultivation, it is necessary to establish an irrigation reservoir to provide sufficient water supply, and at the same time use a drainage system to complete the drainage treatment. When irrigation is carried out, it is necessary to fully understand the local environmental conditions, enable the pollution-free vegetables to grow healthily, and effectively control the water in the planting area. It is also necessary to improve the drainage channel according to the water accumulation situation, and to carry out the overall irrigation in case of drought. By enhancing the scientific nature of irrigation forms, the disease resistance of pollution-free vegetables has been significantly improved.
2.4 Pest Control Technology
Proper use of pesticides can effectively prevent pests and diseases. First of all, according to the actual situation, take certain physical control measures, that is, reduce the use of pesticides by manual cleaning, and also choose to use some natural enemies of pests to reduce pests and diseases, and achieve the purpose of reducing pesticide residues. When planting pollution-free vegetables, controlling the amount of pesticides not only ensures the normal growth of vegetables, but also solves the existing pollution problems.
2.5 Fertilization operation technology
When selecting fertilizers, it is necessary to raise awareness of organic fertilizers and multi-component fertilizers, accurately control dosage, and establish relevant treatment measures according to the demand for nutrients in vegetables. Foliar fertilizer should not be applied in the first month after harvesting vegetables; nitrogen fertilizer should not be added 1 week before harvesting vegetables. In addition, when the fertilizer is treated, adding a certain amount of nitrate can significantly enhance the soil fertility.
The above is the whole content of Hui Nong.com. At this stage, the production of pollution-free vegetables can initially meet people's daily needs. However, as people's requirements for food quality continue to increase, it is necessary to strengthen the cultivation of pollution-free vegetables. The promotion efforts to promote the development of pollution-free vegetables faster and better. Ladies and gentlemen, do you have any promotion of this technology?
