Problems solved by technology

Due to the rapid growth of leafy vegetables, the short cultivation period, and the large amount of fertilizer required, in the traditional planting mode, organic fertilizers are often used in combination with inorganic fertilizers based on nitrogen, phosphorus, and potassium to meet production needs. Low utilization rate can also easily cause damage to the soil structure, increase the accumulation of harmful substances in the soil and pests and diseases, and then affect the yield and quality of leafy vegetables
[0003] The most serious thing is that in the current vegetable planting and production process, the phenomenon of excessive or excessive application of chemical fertilizers and organic fertilizers by producers is becoming more and more serious, and the consequences mainly include the following aspects: (1) The loss of organic fertilizers Extensive use can relieve soil compaction to a certain extent, but antibiotics and hormones in organic fertilizers have become the main source of soil pollution; (2) undecomposed organic fertilizers have become the main source of soil pests and diseases; (3) organic fertilizers The ratio of fertilizer and nutrition does not meet the needs of vegetable growth, and the residual nutrition can also become the main cause of secondary salinization of soil
At the same time, the unbalanced ratio of organic fertilizers and inorganic fertilizers and the excessive application of fertilizers are likely to cause vegetable nutrient deficiency and excessive nitrate content. Therefore, it is urgent to study a nutritional balance of leafy vegetables that can effectively promote vegetable quality and yield. Agents and their methods of application
