Problems solved by technology

In order to solve the plight of cotton planting in the Dongting Lake cotton area, in recent years, Hunan has actively carried out research on the supporting technology of cotton mechanical direct seeding cultivation. After application, although the labor input has been reduced, the cultivation density has also increased (the highest is 6000 plants / mu). However, the ventilation and light transmission in the field is relatively poor, cotton bolls are prone to mildew and rot, and problems such as the need for thinning have not been resolved, resulting in low income and high cost, which is not conducive to the healthy and sustainable development of Hunan's cotton industry.

Embodiment 1

[0027] The cotton light and simple cultivation method suitable for Dongting Lake cotton area of ​​the present embodiment is specifically realized through the following aspects:

[0028] (1) Variety selection: select cotton varieties with insect resistance, early maturity, good yield, tolerance to close planting, and have passed the provincial level or above examination, preferably genetically modified insect and disease resistant varieties, and the seed quality meets the requirements of GB4407.1;

[0029] (2) Sowing time: cotton should be sown in time after rape or wheat is harvested, the sowing date should be no later than May 31, and the sowing depth should be about 2.0cm;

[0030] (3) Planting density: The appropriate planting row spacing is 70cm, and the plant spacing is adjusted according to the soil fertility level. The medium soil soil plots are planted by digging holes with 3,000 holes / mu. Each hole is sown with 3 robust seeds, and the seeding density is 9,000 plants / mu...

Abstract

The invention discloses a light and simple cotton cultivation method suitable for the Dongting Lake cotton area, which is specifically realized through variety selection, sowing time, planting density, fertilization, pest and weed prevention and control, topping, chemical ripening, and harvesting. The method of the invention greatly reduces the management time and labor of the cotton field, and not only increases the cotton planting density to achieve high yield, but also reduces the number of holes in the cotton field to ensure ventilation and light transmission in the field, prevent boll mold and rot, and ensure the quality of cotton.

Description

technical field [0001] The invention relates to a cotton cultivation method, in particular to a cotton light and simple cultivation method suitable for the cotton area of ​​Dongting Lake, and belongs to the technical field of cotton light and simple cultivation. Background technique [0002] Dongting Lake cotton area has abundant sunshine, warm climate, fertile soil and good drainage and irrigation foundation, which is very suitable for cotton growth and is an important commercial cotton production base in my country. In recent years, with the development of society and economy, a large number of rural labor force has been transferred, resulting in shortage of labor resources in Hunan and the whole country, rising wages, lowering the income of cotton planting, frustration of cotton farmers' enthusiasm for cotton planting, and premature aging of cotton is increasing year by year. In order to solve the planting dilemma in the cotton area of ​​Dongting Lake, in recent years, Hu...
