Apply the base fertilizer, roots must be used to apply sufficient amount of organic fertilizer before planting, and use farmyard manure or stacked municipal waste, then add plant ash and superphosphate. The specific dosage depends on the soil fertility, spread over the ground, and then ploughed into the soil.
Topdressing, roots of mustard are used as the first top dressing after the cotyledons of the seedlings are unfolded, and the manure is applied at a ratio of 1:7. After the first inter-emergence, the second fertilizer was applied during the cultivating and weeding, and the application was carried out with a ratio of 1:5. After the seedlings are planted, the plants grow rapidly, need sufficient fertilizer and water, carry out the third top dressing, and apply ammonium sulfate. After entering the rosette period, in order to promote the expansion of the fleshy roots, chase the fourth fertilizer, using urea and potassium sulfate. When entering the fleshy roots, the fifth fat is added, and the nitrogen, phosphorus and potassium compound fertilizers are used to increase the high yield.
Spray surface fertilizer, foliar spray fertilizer can increase production. In the seedling stage, foliar application of borax + plant electronic fertilizer accelerates the metabolic frequency, and activates the plant nutrient-distributing system to produce more than the fertilizer effect. In the early stage of growth, the aqueous solution of ammonium molybdate can be sprayed, and the effect of increasing the yield of the superphosphate can be achieved by spraying the super-calcium phosphate + the fruit of the fruit.
