Embodiment 1

[0024] A method for planting cotton suitable for medium and low fertilizer areas, comprising the following steps:

[0025] Step 1: Turn the soil, sow 20kg / mu of phosphorus fertilizer and nitrogen fertilizer into the soil 3 days before planting in mid-April, and repeatedly turn the soil on the seedbed until the phosphorus fertilizer and nitrogen fertilizer are evenly mixed into the soil, and spray fine water on the seedbed To ensure that the soil in the field is moist, cover with mulch;

[0026] Step 2: Screen seedlings, select cotton seeds with full grains on the outside, soak the cotton seeds in warm water at 50°C for 3 hours, pour off the water, cover them with a damp cloth for 1 hour, and place them in a ventilated environment to maintain a temperature of 30°C for cultivation , wait for 2 days to germinate;

[0027] Step 3: Seedbed management, build a plastic greenhouse with a height of 2m on the seedbed, sprinkle a layer of plant ash with a thickness of 10mm on the seedbe...

Embodiment 2

[0038] A method for planting cotton suitable for medium and low fertilizer areas, comprising the following steps:

[0039] Step 1: Turn the soil, sow 20-30kg / mu of phosphorus fertilizer and nitrogen fertilizer into the soil 3-10 days before planting in mid-April, and repeatedly turn the soil on the seedbed until the phosphorus fertilizer and nitrogen fertilizer are evenly mixed into the soil, and use it on the seedbed The kettle sprays fine water to ensure the soil in the field is moist and covered with plastic film;

[0040] Step 2: Screen seedlings, select cotton seeds with full grains on the outside, soak the cotton seeds in warm water at 60°C for 4 hours, pour off the water, cover them with a damp cloth for 3 hours, and place them in a ventilated environment to maintain a temperature of 35°C for cultivation , wait for 3 days to germinate;

[0041] Step 3: Seedbed management, build a plastic greenhouse with a height of 3m on the seedbed, sprinkle a layer of plant ash with ...

Abstract

The invention discloses a cotton planting method suitable for medium and low fertility areas. The method includes the steps of soil preparation, seed screening and seedling culturing, seedling bed management, seedling bed fertilization, core shearing, seedling transplanting, growth management, fertilization, and harvesting. By means of the cotton planting method suitable for the medium and low fertility areas, the yield is high, the cost is low, the management is easy, each cotton tree bears about 60-80 fruits, the yield per mu is increased by 20-30%, and in a two-row stripped planting mode, the stripped row hole distance is 50*30*25 to 50*30*20 cm, 600-700 holes are formed per mu, and 1.7-5 ten thousand plants are planted per mu; the optimized high-yield specification is configured, on the premise that the irrigation water consumption is not increased, fertilizer is intensively applied, water is effectively used, effective evaporation of soil is turned into effective transpiration of the plants, and the cotton yield in the medium and low fertility areas is effectively increased.

Description

technical field [0001] The invention belongs to the field of cotton planting, and in particular relates to a cotton planting method suitable for medium and low fertilizer areas. Background technique [0002] Cotton is the seed fiber of the Malvaceae cotton plant, native to the subtropical zone. The plant is shrubby and can grow up to 6 meters high in tropical areas, generally 1 to 2 meters. The flowers are milky white, turn dark red shortly after flowering and then wither, leaving small green capsules called cotton bolls. There are cottonseeds in the cotton bolls, and the fluff on the cottonseeds grows from the skin of the cottonseeds and fills the inside of the cotton bolls. When the cotton bolls mature, they crack, exposing soft fibers. The fibers are white or white with yellow, about 2 to 4 cm (0.75 to 1.5 inches) long, containing about 87 to 90% cellulose, 5 to 8% water, and 4 to 6% other substances. [0003] Cotton can be divided into white cotton, yellow cotton, gra...
