Management of fertilization in rapeseed field in seedling stage, application of phosphorus fertilizer to ensure normal growth of rapeseed
Seedling stage rapeseed field management fertilization technology to increase the application of phosphorus fertilizer to ensure the normal growth of rapeseed, rapeseed is a phosphorus fertilizer, there is sufficient supply of phosphate fertilizer, the root system is developed, the plant is robust, the flower buds are more, the flowering is good, the pollination and fertilization is smooth, the seed setting rate is high, the grain full. In the absence of phosphate fertilizer, the red stems of the seedlings are purple, the plants are short, the flower buds are less, the flowering is poor, the seed setting rate is low, the grain is not full, and the yield is significantly reduced. Therefore, rapeseed seedlings should pay attention to the addition of phosphate fertilizer to ensure the supply of phosphate fertilizer. The specific practices are as follows: In the case of rapeseed with five leaves and one heart, apply a phosphate fertilizer to the roots, apply 30~40 kg of calcium phosphate or calcium magnesium phosphate per acre, and evenly spread it in the rape field. Before the fertilization, first fill the “running and water†to make the soil of the rapeseed field moist, so as to facilitate the soil to absorb the phosphate fertilizer and improve the fertilization effect. Or apply a clean water after applying the phosphate fertilizer to make the phosphate fertilizer fully contact with the soil to facilitate the root absorption of the rapeseed. In addition, the leaves should be sprayed 2~3 times with 0.2%~0.3% potassium dihydrogen phosphate aqueous solution, or 600~800 times Xingpeng Phosphate Potassium No.1 aqueous solution, spray once every 7~10 days, evenly spray all the leaves to It is advisable to start dropping water drops.
