[0024]Example 1
[0025]1. Take soil samples in March 2019 to determine the basic force measurement of nutrients such as soil quick-acting nitrogen, speed phosphorus and quick-acting potassium.
[0026]2, according to the basic fertility of the land, on April 15th, formula fertilization: nitrogen fertilizer for urea, 20 kg / mu, phosphate fertilizer application is calcium phosphate, the application amount is 0kg / mu, so soil quick-active phosphorus content is 45mg / kg, potassium fertilizer Potassium chloride is administered, and the amount of application is 15kg / mu, soil soil's quick-fitting potassium content is 320 mg / kg.
[0027]3, after the fertilizer is sure, the irrigation is 100m.3 / mu.
[0028]4, on April 25th, a spiral seed was sown, and the variety was selected as the routine cotton cotton 803 in the Yellow River Basin.
[0029]5. Using film coverage, 66cm and other line spacing.
[0030]6, after the cotton seedlings, according to 5,000 / mu of density, the plant spacing is 20.2 cm.
