Embodiment 1

[0020] A method for growing cotton seedlings, specifically comprising the steps of:

[0021] 1) Seedbed preparation: Choose a flat terrain, leeward to the sun, convenient drainage and irrigation, fertile soil, close to water sources and fields, and no disease as the seedbed. Use shovel or hoe to dig out the seedbed, tamp and level the bottom and surrounding areas, remove stones, Plant rhizomes and sharp hard objects, etc., then wet the surrounding and bottom of the seedbed to soften the hard soil, and finally lay a 0.06mm polyethylene film on the bottom and surrounding of the seedbed to make the back of the film close to the soil;

[0022] 2) Prepare seedling nutrient solution: add special fertilizer for cotton water floating seedlings and water to prepare a mother liquor with a mass concentration of 5%, then mix the mother liquor and anti-disease and insect pest agents according to the weight ratio of 1:0.2, pour it into the nursery pond, and add the mother liquor 60 times th...

Embodiment 2

[0031] A method for growing cotton seedlings, specifically comprising the steps of:

[0032] 1) Seedbed preparation: Choose a flat terrain, leeward to the sun, convenient drainage and irrigation, fertile soil, close to water sources and fields, and no disease as the seedbed. Use shovel or hoe to dig out the seedbed, tamp and level the bottom and surrounding areas, remove stones, Plant rhizomes and sharp hard objects, etc., then wet the surrounding and bottom of the seedbed to soften the hard soil, and finally lay a 0.08mm polyethylene film on the bottom and surrounding of the seedbed to make the back of the film close to the soil;

[0033] 2) Preparation of seedling nutrient solution: add special fertilizer for cotton water floating seedlings and water to prepare a mother liquor with a mass concentration of 8%, then mix the mother liquor and anti-disease and insect pest agents according to the weight ratio of 1:0.4, pour it into the nursery pond, and add the mother liquor 65 t...

Embodiment 3

[0042] A method for growing cotton seedlings, specifically comprising the steps of:

[0043] 1) Seedbed preparation: Choose a flat terrain, leeward to the sun, convenient drainage and irrigation, fertile soil, close to water sources and fields, and no disease as the seedbed. Use shovel or hoe to dig out the seedbed, tamp and level the bottom and surrounding areas, remove stones, Plant rhizomes and sharp hard objects, etc., then wet the surrounding and bottom of the seedbed to soften the hard soil, and finally lay a 0.1mm polyethylene film on the bottom and surrounding of the seedbed to make the back of the film close to the soil;

[0044] 2) Preparation of seedling nutrient solution: add special fertilizer for cotton water floating seedlings and water to prepare a mother liquor with a mass concentration of 6%, then mix the mother liquor and anti-disease and insect pest agents according to the weight ratio of 1:0.3, pour it into the nursery pond, and add the mother liquor 70 ti...

Abstract

The invention discloses a cotton seedling raising method. The cotton seedling raising method includes the steps that an appropriate section is selected as a seedling bed, after cleaning, a polyethylene thin film is laid in the seedling bed, a prepared cotton water floating seedling raising nutrient solution is poured into the seedling bed to be ready for use, then, a mixed substrate is evenly poured into a seedling raising disc, seeds which are soaked, coated and germinated are sowed in the substrate in the seedling raising disc, after sowing is completed, the seedling raising disc is immediately placed into the seedling bed and is covered with a film, humidity and heat are preserved, after seedlings emerge, ventilation is conducted to harden the seedlings, a root growth promoting agent isadopted to irrigate the seedlings when cotyledons of the cotton seedlings spread flat, and finally, when the cotton seedlings grow to have three unfold leaves and one fold leaf, transplanting can beconducted. The cotton seedling raising method is simple and feasible, time and labor are saved, the seedling emergency rate is increased, the yield and income are obviously increased, economic benefits of cotton planting are greatly improved, the cotton seedling raising method has high agricultural promotional value, cultivated cotton seedling root systems are strong and have high vitality, the transplanting survival rate is high, the transplanted seedlings have certain disease and pest resistance capabilities, and the quality of cotton is good.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a cotton seedling raising method. Background technique [0002] In terms of botanical classification, cotton belongs to the angiosperm Malvaceae, cotton genus, and is an annual subshrub. There are also perennial shrubs or small trees in the tropics and subtropics. Cotton is an important economic crop in my country, and cotton fiber is an important raw material and foreign exchange earner for the textile industry. Materials; Cottonseed is an important source of edible oil and chemical raw material. Generally, the oil content of cottonseed after delinting reaches 22-25%, and the oil content of cottonseed after shelling reaches 35-45%. Cottonseed hulls are cheap chemical and edible fungus raw materials ; Cottonseed cake is a high-quality source of feed and fertilizer. The cottonseed powder after oil extraction contains 45-50% protein, and contains a variety of vitamins. It c...
