Plastic cup direct sowing cotton seed sowing and seedling growing method

Abstract

The invention discloses a plastic cup direct sowing cotton seed sowing and seedling growing method, which is characterized in that: seeds are sown during a period from April 15th to May 10th every year; the temperature of the soil which is 5 centimeters below the soil surface is kept above 14 DEG C constantly; when soil tilth is proper, ridges and holes are made in a leveled cotton field; 1 to 2 high-quality cotton seeds are sown in each hole; the cotton seeds are planted in soil at a 2 to 3 centimeter distance from the surface of the soil; each hole in which the cotton seeds are sown is covered by a plastic cup; the mouth of each plastic cup is put in soil and 2 to 3 centimeters away from the surface of the soil; the cotton seeds is in the mouth of each plastic cup; the height of the plastic cups is 10 to 16 centimeters and the volume of the plastic cups is 240 to 320 milliliters; 3 to 5 days after the germination of cotton seedlings, a hole is formed in the side wall of each plastic cup; and when 25 to 40 percent of cotton seedlings in the cotton field grows to the height of the top of the plastic cups, all plastic cups can be removed at one time, and the final singling of the seedlings can be performed. The method, when used for sowing and seedling growing, has the advantages of high production efficiency, small risks, low labor intensity, simple management working procedures and high survival rate of cotton seedlings and the like.

Description

technical field [0001] The invention relates to a cotton sowing and seedling raising method, in particular to a plastic cup direct seeding cotton seedling raising method. Background technique [0002] Nutrition pot seedling transplanting technology: In the 1980s, nutrition pot seedling transplanting, as an important cultivation measure for high and stable cotton production, was widely promoted and applied in the cotton areas of the Yangtze River and the Yellow River Basin in my country, and achieved a significant effect of increasing production. my country has a lot of people and less land, conflicts over land competition for grain and cotton, and increasing the multiple cropping index has played a huge role in promoting a double harvest of grain and cotton [1]. However, with the development of the economy, the adjustment of the agricultural industrial structure, the transfer of rural labor forces, and the sharp rise in labor prices, the traditional nutrient pot seedling tran...

Problems solved by technology

The main problem of the above-mentioned matrix seedlings is that the survival rate of cotton seedlings in soilless seedling transplanting is difficult to guarantee, and the slow seedling period is long, and the risk of large-scale application is relatively high.

Other seedling raising methods are still in the stage of experimental exploration and have not been widely applied
