1, seed treatment
In the process of vegetable planting, the selection and treatment of seeds are also very important, which has a great influence on the yield and quality of vegetables. Select high-quality vegetable seeds to ensure that the vegetable seeds have strong resistance to stress, thus reducing the subsequent planting procedures, thus avoiding a large number of pesticide residues in vegetables and reducing the impact of pesticide residues on consumers' health.
Before sowing, the seeds should be properly treated to ensure the rationality and scientificity of the treatment method, so as to improve the resistance to sowing and reduce the occurrence of pests and diseases. Choose reasonable nursery land, strengthen pest control, and reduce the impact of pests and diseases on nursery work. In addition, the soil must be treated before sowing to ensure that the soil meets the growth requirements of seeds, thus ensuring the normal growth of seeds.
2, the use of fertilizer
Vegetables have a great demand for nutrients, and relying solely on nutrients in the soil can not meet the growth demand of vegetables, and it will lead to the lack of necessary guarantee for vegetable quality. Therefore, we must pay attention to the application of chemical fertilizers, provide necessary nutrition for vegetables, ensure the normal growth of vegetables and improve the quality of vegetables. Choose the right fertilizer to ensure the rationality and scientificity of fertilizer selection. At the same time, pay attention to the collocation of fertilizers, reasonably collocate organic fertilizers and inorganic fertilizers to promote the growth of vegetables.
3, the use of pesticides
Pesticides play an important role in vegetable growth. Rational use of pesticides can increase vegetable yield and maximize economic benefits. However, it is worth noting that excessive use of pesticides will cause a large number of pesticide residues on vegetables, threatening the health and safety of consumers. Therefore, attention should be paid to controlling the dosage of pesticides to ensure the rationality of pesticide dosage.
? In addition, we should pay attention to the selection of pesticide varieties, try to use low-residue pesticides, reduce pesticide residues and ensure the safety of vegetables on the premise of ensuring the effect of pest control. It is necessary to pay attention to the selection of drug use time, master the occurrence law of pests and diseases, carry out pest control as soon as possible, and reduce drug use.
4. Irrigation management
Irrigation management is the key to vegetable management and has a great influence on vegetable production. In irrigation management, it is necessary to formulate a scientific and reasonable irrigation plan according to the actual situation, provide stable and reliable water resources for vegetable growth, pay attention to water quality management, ensure clean water quality and avoid affecting vegetables. Irrigation work should be carried out according to the characteristics of vegetables, and appropriate adjustments should be made according to external factors such as soil and climate to ensure scientific and reasonable irrigation work. It is worth noting that the demand for water resources of the same vegetable at different growth stages may also be very different, so we should pay attention to it when planting.
