A kind of medium for raising seedlings of crop seeds and its preparation method

Abstract

The invention discloses a medium for growing seedlings of crop seeds, which belongs to the technical field of agricultural planting and is prepared from the following raw materials in parts by weight: 20-30 parts of cooked field soil, 15-20 parts of vermiculite, 5-10 parts of shrimp and crab shell powder, 5-10 parts of plant ash, 5-10 parts of grape pomace, 5-10 parts of corncob powder, 3-5 parts of diatomaceous earth, 0.1-1 part of water-retaining agent, and the invention also provides a preparation method of a medium for raising seedlings of crops , mix grape skin pomace, corncob powder with cooked field soil and vermiculite for aging and then mix with other raw materials to obtain the cultivation base for crop seed seedlings; plant ash, corncob powder, shrimp and crab shell powder added in the culture medium of the present invention As well as grape pomace are wastes obtained from industrial and agricultural production, the raw materials are cheap and easy to obtain, non-toxic and pollution-free, and the waste can be reused, which is in line with the theme of green and sustainable development.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a medium for raising seedlings of crop seeds and a preparation method thereof. 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 ...

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
