Embodiment 1
[0025] 1. Soil samples were taken in March 2019 to measure the basic soil fertility of soil nutrients such as available nitrogen, available phosphorus and available potassium.
[0026] 2. According to the basic fertility of the land, formula fertilization will be carried out on April 15: urea is applied to nitrogen fertilizer, and the application rate is 20kg / mu; Potassium chloride is applied at an application rate of 15kg / mu, so that the soil available potassium content is 320mg / kg.
[0027] 3. Irrigate after spreading the fertilizer, and the amount of irrigation per mu is 100m 3 / mu.
[0028] 4. Rotary tillage and harrowing were carried out on April 25 for sowing, and the selected variety was Jimian 803, a medium-maturing conventional cotton in the Yellow River Basin.
[0029] 5. Cover with plastic film and plant with equal row spacing of 66cm.
[0030] 6. After the emergence of cotton seedlings, the seedlings are determined according to the density of 5000 plants / mu, and...
