Cotton seedling substrate

Abstract

The invention discloses a cotton seedling substrate, and belongs to the technical field of soilless culture. The substrate is prepared by uniformly mixing the following components in percentage by weight: 10 to 20 percent of vinegar residues, 15 to 30 percent of manioc waste, 10 to 20 percent of plant ash, 10 to 20 percent of vermiculite, 10 to 25 percent of turf, a little inorganic fertilizer, wherein 0.3 to 0.5kg of ammonium sulfate-nitrate, 0.1 to 0.2kg of potassium chloride, 0.1 to 0.2kg of monoammonium phosphate are added into each cubic meter of cotton seedling substrate. According to the cotton seedling substrate, organic wastes are mainly used as raw materials and fermented at high temperature to produce soilless culture substrate, so that waste materials are changed into valuable things, and harmful substances are changed into benefits things. The substrate has the advantages of rich nutrition, good caking property, water and fertilizer conservation, weight volume weight, easily available seedling, short cultured recovery period, quick seedling and the like, and is convenient to transport, and suitable for cotton seedling.

Description

technical field [0001] The invention relates to a soilless cultivation substrate for crops, in particular to a cotton seedling raising substrate, and belongs to the technical field of soilless cultivation. Background technique [0002] Soilless cultivation refers to the method of cultivating crops with substrates instead of natural soil. It is a high-yield, high-quality advanced technology that saves water, fertilizer and labor. [0003] Substrate cultivation is a method with the largest promotion area in soilless cultivation. It fixes the root system of the crop in an organic or inorganic substrate, and supplies the crop nutrient solution through drip irrigation or trickle irrigation. At present, most countries in the world use gravel, sand, mud (grass) charcoal, vermiculite, perlite, rock wool, sawdust, etc. as fixed substrates. [0004] With the promotion and application of soilless cultivation technology, the demand for substrates is increasing, and enterprises speci...

Problems solved by technology

For a long time, in my country's cotton production, the most widely used seedling substrate is the soil matrix nutrition pot composed of soil and organic fertilizer. However, in the application of the nutrition pot, the production process is complicated, the labor load is large, and the cost is high, so it is not suitable for factories. Disadvantages such as chemical seedling cultivation, small pot body, and insufficient nutrition; Chinese patent CN 1274204C discloses the invention patent of "A Kind of Cotton Soilless Seedling Raising Substrate and Its Application" by Mao Shuchun, Cotton Research Institute, Chinese Academy of Agricultural Sciences, and specifically discloses that the substrate is composed of It is made by mixing vermiculite, river sand and sawdust in a certain proportion. The matrix has loose texture, good air permeability and low cost.

However, it also has few nutrients, poor water holding capacity, poor adhesion, and less substrate for root bonding when transplanting seedlings, thereby affecting the survival rate. Relevant literature search finds that in the prior art, organic waste There is no public report on the special seedling substrate for cotton that is rich in nutrition, good in rooting, and high in survival rate as the main raw material.
