Nutrition pot seedling raising method of cotton

Abstract

The invention discloses a cotton nutrient pot seedling raising method, which comprises the following implementation steps: (1) seedbed preparation; (2) nutrient soil preparation; (3) bed building and potting; (4) seeding; (5) seedbed management; (6) Disease prevention and control. Compared with the previous cotton direct seeding technology, the method for growing cotton seedlings in a nutritional bowl of the present invention is beneficial to the cultivation of strong seedlings, and realizes dense planting of all seedlings. The seedling cultivation in the seedbed is 20 to 30 days earlier than the sowing period in the field, and the cotton seedlings are unearthed early, complete, uniform, strong, and effective. It is beneficial to realize the early growth of strong seedlings, make full use of light and heat resources, and effectively extend the growth period; increase the yield and increase the income by 8% to 15% per mu of cotton field, and increase the income by 100 to 130 yuan / mu, and it is also conducive to staggering the busy season of farming: In addition to the work of transplanting to the field, the work of cotton seedling raising is completed before the busy season of wheat harvest and wheat seeding, so that the busy time can be done in the leisure time, which is convenient for busy farming arrangements, saves manpower, material resources and other production costs, and greatly improves the production cost. labor productivity.

Description

technical field [0001] The invention relates to a method for raising seedlings in a cotton nutrient bowl, belonging to the technical field of crop cultivation. Background technique [0002] Cotton belongs to the angiosperm Malvaceae genus in botanical classification. It is an annual subshrub, and there are also perennial shrubs or small trees in the tropics and subtropics. Cotton is an important economic crop in my country. Cotton fiber is an important raw material and foreign exchange earning material for the textile industry; cottonseed is an important source of edible oil and chemical raw material. Generally, the oil content of cottonseed after delinting reaches 22% to 25%, and the oil content of cotton kernel after husking reaches 35% to 45%. %; Cottonseed husk is a cheap chemical and edible fungus raw material; Cottonseed cake is a high-quality source of feed and fertilizer. The cottonseed powder after oil extraction contains 45% to 50% protein and contains various vi...

Problems solved by technology

At present, there are many cotton seedling raising methods, but the quality of seedlings is quite different, the quality is not high, the bottleneck of transplanting survival rate cannot be further improved, and the cultivation method is improper, which restricts the improvement of cotton production and quality; in the annual seedling season, there are always farmers due to Improper seedling raising methods lead to dead cotton seedlings and the occurrence of various diseases and insect pests, resulting in low quality of cotton seedlings and a significant reduction in yield, which affects the normal income of farmers
