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...

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.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a cultivation method in the Hebei area that takes into account both plant type shaping and yield of machine-picked cotton. Background technique [0002] Cotton is the main economic crop in Hebei Province, mainly distributed in southern Hebei. In recent years, due to the increase in cotton planting costs and the lack of rural labor force, farmers' increase in cotton production but not their income is one of the main factors restricting cotton planting in the Yellow River and Yangtze River basins. Cotton production has gradually shifted to Xinjiang. Machine-picked cotton is an agricultural production method that replaces manual picking of flowers with mechanical cotton-picking equipment. It can reduce labor intensity and improve production efficiency. It is one of the hot spots of cotton science and technology workers. The research and promotion of machine-picked cotton c...
