Sheep manure seedling breeding substrate used for seedling breeding of asparagus lettuce

Abstract

The invention discloses a sheep manure seedling breeding substrate used for seedling breeding of asparagus lettuce. The seedling breeding substrate is prepared from, by weight, 100-120 parts of soil in which soya beans have been planted, 15-20 parts of clam shells, 20-30 parts of sheep manure, 10-15 parts of biogas residue, 6-8 parts of clinopodium megalanthum, 8-10 parts of turraea pubescens, 11-13 parts of hypericum ascyron, 6-8 parts of dischidia esquirolii, 0.3-0.5 parts of copper peptide, 0.4-0.6 parts of mesylate, 0.8-1.2 parts of sodium carboxymethylcellulose, 0.1-0.3 parts of sodium rosiglitazone, 3-6 parts of ammonium sulfate, and 2-4 parts of magnesium sulfate. The sheep manure seedling breeding substrate has no pollution on environment. The planted asparagus lettuce is green and healthy. By using the seedling breeding substrate for seedling breeding of asparagus lettuce, germination rate of seeds is high, germination period of the seeds is short, and after the seeds are germinated, growth speed is high and the seedlings are healthy.

Description

technical field [0001] The invention belongs to the field of vegetable planting, and in particular relates to a sheep dung seedling raising substrate for lettuce seedling raising. Background technique [0002] Lettuce is an annual or biennial vegetable of Compositae. It is one of the staple vegetables in my country and has a large cultivation area. Erbaipi, Jianye, and Hangsihong are the main lettuce varieties in China, especially in the Yangtze River Basin, and the amount of seeds used is extremely large. In the south, lettuce seeds are generally harvested in May, and sown from August to November must be stored for a period of time. During the storage process, the seeds have to experience high temperature and high humidity seasons, which are prone to aging and cause a decline in vigor, reducing the germination rate of seeds, which is of great concern to agriculture. Production brings varying degrees of losses. Therefore, in addition to the soaking and activation treatment...

Problems solved by technology

However, fresh sheep manure generally contains a large number of pathogenic bacteria, live insect eggs, and other toxic and harmful substances, and the available nutrients N, P, and K are released slowly, which is not conducive to fully exerting the role of fertilizers, and is not suitable for direct use.
