Embodiment 1

[0030] A method for planting cotton with high yield and low harm, comprising the following planting steps:

[0031] 1) Seed selection and seedling cultivation: select a healthy cotton seed with full grains and no diseases, Zhongmian No. 12, pretreat the seeds and reserve them; use the seedling soil to make a nutrient bowl with a length of 8-12m and a width of 1.2-1.5m at the leeward and sunny place Bed, sow cotton seeds in nutrient pots, 1-2 seeds in each pot, after sowing, cover the surface with soil and spray 30% carbendazim 2000 times liquid, and then set up a film shed to keep the seedlings warm;

[0032]2) Seedbed management: In the process of seedling cultivation, according to the different stages of emergence, seedling preservation, seedling training, and strong seedlings, heat preservation and moisturizing are carried out in a targeted manner, and timely weeding, insect control, core cutting, and spraying 25-30ppm of metrendamine solution and diseases Control solution ...

Embodiment 2

[0044] Based on the high-yield and low-harm cotton planting method proposed in the embodiment, the seed treatment and pest control parameters of the present embodiment are as follows:

[0045] The pretreatment in step 1) specifically includes soaking the seeds in cold water for 5-10 hours, then taking them out and soaking them in 3wt% brine containing glycine and copper acetate for 1-2 hours, then adding an appropriate amount of heather extract to them, and ultrasonically treating them After 2-3 minutes, take it out and put it in rice husk or crushed straw to keep warm and accelerate germination; among them, the mass ratio of glycine, copper acetate, heather extract to warm water is 0.5:1:4:100, and the ultrasonic treatment frequency is 21KHz.

[0046] The seedling soil in step 1) comprises the following mass fractions, 15-18 parts of sandy loam soil, 10-12 parts of river mud, 5-8 parts of humus soil, 4-6 parts of decomposed organic fertilizer, 2-3 parts of plant ash, and 0.5 p...

Embodiment 3

[0052] Based on the high-yield and low-harm cotton planting method proposed in the embodiment, the seed treatment and pest control parameters of the present embodiment are as follows:

[0053] The pretreatment in step 1) specifically includes soaking the seeds in cold water for 5-10 hours, then taking them out and soaking them in 3wt% brine containing glycine and copper acetate for 1-2 hours, then adding an appropriate amount of heather extract to them, and ultrasonically treating them After 2-3 minutes, take it out and put it in rice husk or crushed straw to keep warm and accelerate germination; among them, the mass ratio of glycine, copper acetate, heather extract and warm water is 1:1:2:100, and the ultrasonic treatment frequency is 22KHz.

[0054] The seedling soil in step 1) comprises the following mass fractions, 15-18 parts of sandy loam soil, 10-12 parts of river mud, 5-8 parts of humus soil, 4-6 parts of decomposed organic fertilizer, 2-3 parts of plant ash, and 0.5 pa...

Abstract

The invention relates to the technical field of agricultural planting, and specifically proposes a cotton planting method with a high yield and a low pest rate. The method includes the following planting steps of seedling selection, seedbed management, transplanting, field management and harvesting. Through reasonable treatment and strengthening of cotton seeds and effective disease control and pest prevention of cotton plants, the survival rate of cotton at the seedling stage is greatly increased, the disease resistance of the cotton at the seedling stage is greatly improved, the roots of seedlings are developed, the stems of the seedlings are robust, and the seedlings have a strong portability and a long-lasting effect of antibacterial and anti-infection active ingredients and also havea high survival rate and a fast growth resume rate after transplanting; scientific field management is combined, so that the comprehensive resistance to lodging, pests and diseases is significantly improved, the pest rate of the cotton plants is reduced by 25% or above, the yield is increased by 46% or above, and the economic benefits are significantly increased.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a high-yield and low-harm cotton planting method. 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 1-2 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 long, containing about 87-90% cellulose, 5-8% water, and 4-6% other substances. [0003] Cotton can be divided into white cotton, yellow cotton, gray cotton and colored cotton according to its color...
