Culture medium for crop seedling culture

Abstract

The invention discloses a culture medium for crop seedling culture. The culture medium needed by each part of seed comprises, by weight, 16-20 parts of kaolin, 6-11 parts of soil conditioner, 26-30 parts of perlite, 7-10 parts of Chinese chestnut involucre, 6-10 parts of peanut shell, 8-11 parts of molasses fermentation broth, 5-7 parts of bamboo-willow sawdust, 2-4 parts of Larix gmelinii needles, 8-10 parts of animal manure, 2-4 parts of sustained-release fertilizer, 2-4 parts of stabilizer, 0.02-0.04 part of agglomerating agent and 40-45 parts of water. The culture medium has the advantagesthat various elements, effective components and nutrition are balanced, the crop quality and yield can be improved to the maximum extent, and the culture medium is reasonable in nutrition proportion,good in rain wash resistance, simple in formula, natural and rich, safe, environmentally friendly and harmless in raw materials, easy in raw material obtaining, capable of achieving resource recycling, capable of lowering cost, green and environmentally friendly, stable in performance, good in fertilizer efficiency, capable of enhancing soil fertility and capable of providing material guarantee for fertile soil engineering.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a medium for growing seedlings of crop seeds. Background technique [0002] Seedling medium refers to the growth medium that can provide nutrients for crop seed germination and seedling growth. In addition to supporting and fixing seeds and seedlings, it is more important to act as a carrier of nutrients and water, so that nutrients from itself and from the environment The nutrients and water in the seedlings can be effectively supplied and buffered, so that the seeds can germinate smoothly, and the roots of the seedlings can absorb nutrients and grow. [0003] At present, the substrate materials for seedling cultivation and culture used in the market include peat, rock wool, vermiculite, perlite, bagasse, mushroom bagasse, gravel and ceramsite, among which rock wool and peat are the most widely used in the world and are recognized as the most important in the world...

Problems solved by technology

However, with the large-scale use year by year, its negative effects on society and the ecological environment are becoming more and more obvious. On the one hand, because rock wool is not degradable, extensive use will cause secondary pollution to the environment; on the other hand, peat is a non-renewable resource. , Excessive mining has the risk of depletion; therefore, it is very important to seek and discover good seedling substrates that are easy to obtain and cheap, and can replace polluted materials such as rock wool
