Problems solved by technology

In addition, the existing methods for producing horticultural substrates all use composting and fermentation, which has disadvantages such as uneven fermentation temperature, need to turn the compost, and long fermentation time. This is not only time-consuming and laborious, but also the performance of the substrate obtained by fermentation is not ideal.

Abstract

The invention provides a method for making horticultural substrate by means of the mixed fermentation of corn stalk powder and peanut shell powder. The method carries out production according to the following steps of: (1) materials mixing; (2) high-temperature fermentation; (3) intermediate-temperature fermentation; (4) after ripening fermentation; (5) drying and packaging. The method takes corn stalk powder and peanut shell powder as fermentation raw materials, and has easily obtained raw materials and low cost which is reduced more than 40 percent as compared with grass carbon substrate; meanwhile, the method adopts staged temperature-control fermentation with the high-temperature fermentation stage beneficial to sterilization and the intermediate-temperature fermentation stage propitious to quicken up the decomposition of pectin, starch and saccharide while reducing the decomposition of lignin, hemicellulose and cellulose, thereby maintaining the particle diameter and the mechanical strength of lignin, hemicellulose and cellulose and meeting the special requirements of horticultural production on the stability of substrate volume; moreover, the method can ensure that the carbon-nitrogen ratio of the substrate reaches to 45- 60 to 1 which is higher than the carbon-nitrogen ratio (30 to1) of the prior high-temperature compost and is propitious to reduce the EC value of horticultural substrate.

Description

technical field [0001] The invention relates to a production method of a horticultural substrate, in particular to a production method of a horticultural substrate used for horticultural seedling raising and cultivation. Background technique [0002] Peat is currently the most widely used horticultural seedling and cultivation substrate at home and abroad. Excessive exploitation of peat will destroy forests, cause environmental degradation, and increase the greenhouse effect. The production areas of peat carbon in my country are mainly concentrated in the northeast and southwest areas with inconvenient transportation, and long-distance transportation leads to high cost of peat carbon application. In foreign countries, the use of sawdust fermentation to produce substrates to replace peat has been commercialized. Corn and peanuts are important crops in my country. A large amount of corn stalks and peanut shells are produced every year. In rural areas, a large amount of corn s...
