Abstract

The invention discloses a cultivation method considering both machine-harvested cotton plant type shaping and yield in the Hebei region. The method comprises the following steps that a, a machine-harvested cotton field is fertilized on April 15th with the application amount of nitrogen fertilizer being 18-22kg/mu; after phosphate fertilizer is applied, the content of available phosphorus in soil is 7.4-63.4 mg/kg; after potash fertilizer is applied, the content of quick-acting potassium in soil is 265-398 mg/kg; irrigating is carried out after fertilization; b, rotary tillage sowing is carried out on April 25th, covering is carried out one line by one film, planting is carried out at equal line spacing, and the line spacing is 64-68 cm; c, after seedlings emerge, final singling is conducted according to the planting density of 5000-6000 plants per mu; d, full-course chemical control is carried out on the cotton growth period, and mepiquat chloride is used for regulation and control for a small amount and multiple times; and 10-50g/mu mepiquat chloride is sprayed at the end of July for chemical capping. The method has the characteristics of quickness, convenience and cost saving, the plant type suitable for machine picking of cotton can be shaped, and the cotton yield can be increased.

Example Embodiment

[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.
[0031]7, cotton full-time fertility period implements full-time control, according to rainfall and cotton longitation, regulate DPC usage, a small amount, light control, and later re-control. Specifically: the seedling period is 0.5g, the bud is 2.0g, the initial flowering period is 3.0g, and the flowers are 5.0g. At the end of July, DPC30G / mu was sprayed at the end of July, and the chemical cap was carried out. The spray method is: 10kg of the shrinking amtrium, formulated into the amount of medicinal solution per mu, using the sprayer in the evening, and the top of the cotton plant is 30 cm, evenly ejected.
[0032]8. Other non-mentioned Daejeon management measures are used to regular management methods. Its strainfigure 1 Indicated.

[0036]3, after the fertilizer is sure, the irrigation is 100m.3/mu.
[0037]4, on April 25th, the sowing of the spin cultivation, the selection of varieties are cooked in the Yellow River Basin. Cotton and cotton 315.
[0038]5. Using film coverage, 66cm and other line spacing.
[0039]6. After the cotton seedlings, the sediment is used according to 6000 strains / mu of density, and the straits are 20.2 cm.
[0040]7, cotton full-time fertility period implements full-time control, according to rainfall and cotton longitation, regulate DPC usage, a small amount, light control, and later re-control. Specifically: 0.5 g of the seedling period, 2.0g of the bud, 3.5g of the initial flowering period, and 5.5g in the flowers. At the end of July, DPC20g / mu was sprayed, and the chemical cap was carried out. The spray method is: 10kg of the shrinking amtrium, formulated into the amount of medicinal solution per mu, using the sprayer in the evening, and the top of the cotton plant is 30 cm, evenly ejected.
[0041]8. Other non-mentioned Daejeon management measures are used to regular management methods. Its strainfigure 2 Indicated.
