How to fertilize cotton?

How to fertilize cotton? Please introduce the method of planting cotton can refer to the following methods of fertilization: 1, the chemical fertilizer used in the base fertilizer can be sprinkled on the surface in front of the cultivated land, and turned into the ground together with farm manure. In this way, it can be applied deeply and evenly, with less nutrient loss, and can be absorbed and utilized by cotton roots distributed everywhere. 2. Install a fertilizer applicator on the planter and sow at the same time. Sow fertilizer at the front, apply it in the middle of two rows of cotton, apply 8 to 10 cm deep, and sow seeds later. In this way, the operation is labor-saving, the fertilizer is concentrated, the nutrient loss is less, and the seedlings are used quickly. 3. Before sowing, design the row spacing and the number of rows, insert the mark, first apply a row of fertilizer in the middle of the reserved two rows of cotton, apply more than 10 cm deep, and then sow, so that the fertilizer is applied deeply. 4. If rotary tillage is used instead of ploughing, fertilizers can also be sprinkled on the surface before rotary tillage, but rotary tillage should be as deep as 15 cm as far as possible, and shallow rotation after fertilization is most avoided, leaving most of the fertilizers in the upper layer of the soil, resulting in great loss of nutrients. No matter fertilizing before cultivated land or before rotation, it can be irrigated after tillage to make soil moisture. According to the calculation of 60 to 80 square meters of irrigation per mu, the water depth is 9 to 12 centimeters, and the fertilizer will not seep into the ground with the water, but will be preserved in the shallow soil layer of the surface, which can be absorbed and utilized by cotton roots. The application of base fertilizer is a key measure for high yield of cotton, which is related to cotton yield and cotton planting benefit.
