Factory cotton seedling raising process

Abstract

The factory cotton seedling raising process is one combination of factory facility protection and no-soil cotton seedling raising, the factory facility is for concentrated protection of seedlings and the no-soil cotton seedling raising can ensure the high quality of cotton seedlings. The factory cotton seedling raising process includes adopting greenhouse to eliminate the effect of bad weather condition and other adverse conditions, no-soil cotton seedling raising, sound seedling management, chemical treatment of the no-soil culture medium, etc.

Description

technical field [0001] The invention relates to a factory cotton seedling raising method, which belongs to the field of agricultural seedling raising. Background technique [0002] In my country's cotton production, soil nutrition pot seedling transplanting technology is an advanced and practical cotton cultivation technology, which accounts for 40% to 60% of the total cotton field area in perennial use. It has a certain promoting effect on cotton early maturity and increased yield. However, with the development of social production, the soil nutrition pot seedling transplanting technology has exposed many problems that need to be solved urgently: ① It is necessary to make a pot in the seedling raising, and the pot body is inconvenient to transplant due to the heavy load, so the There is a lot of labor required in the link, which is not labor-saving and labor-saving; ②The pot soil in the seedlings is contaminated with bacteria, which makes it difficult for the seeds to emer...

Problems solved by technology

However, with the development of social production, the soil nutrition pot seedling transplanting technology has exposed many problems that need to be solved urgently: ① It is necessary to make a pot in the seedling raising, and the pot body is inconvenient to transplant due to the heavy load, so the There is a lot of labor required in the link, which is not labor-saving and labor-saving; ②The pot soil in the seedlings is contaminated with bacteria, which makes it difficult for the seeds to emerge, the seedlings are weak, the seedlings are difficult to maintain, the seedlings are difficult, and the risk of seedlings in the seedlings is high; There are few seedlings available before planting; therefore, it is necessary to increase the amount of pot making and seeding, resulting in an increase in seedbed land and seed use, which cannot save land and planting to the greatest extent; ③The technology is seriously "degraded", the pot body is small, and the pot body is thin ;Manual management is extensive, the seedlings are small and weak; ④In addition, it is impossible to carry out industrial seedling cultivation and mechanized transplanting operations, which requires a lot of manpower and material resources

However, since the types and technical parameters of seedling raising factories are mostly different, seedling raising risks often occur in cotton seedling raising, which causes a decline in the quality of seedling raising, resulting in poor quality of transplanting.
