Everyone knows the eight-character policy of agriculture, including water, fertilizer, soil, planting, density, safety, management and industry.
According to your description, fertilizers and seeds rank in the top four. In our planting process, we should pay attention to the following methods to prevent seedlings from burning: 1 Apply organic fertilizer that is not fully decomposed and fermented. Second, the amount of chemical fertilizer is unreasonable. Third, the amount of fertilization is too large. Fourth, sow fertilizer at the same time. Fifth, watering is too late.
For example: first, when fertilizing vegetable seedlings, it needs to be turned over by more than 25 cm. If the amount of fertilizer used is too large, it is likely to cause seedling burning if the rotary tiller is used to rotate the ground.
The second is to apply immature organic fertilizer, which contains more uric acid and urine alkali. After the fertilizer is planted, it will cause secondary fermentation and seedling burning.
Thank you for your question.
