Ecotypic pure substance of siolless culture from barnyard manure of sheep in grassland

Abstract

A matrix for soilless culture of plant is prepared from the barnyard dung of sheep through fermenting, baking, pulverizing and granulating. Its advantages are complete nutrients, no pollution, and high yield and quality of plant.

Description

technical field [0001] The invention belongs to the field of agricultural planting, and in particular relates to an ecological soilless culture substrate and a use method in the category of gardening facilities. Background technique [0002] Sheep manure is a high-quality, full-nutrition organic fertilizer. Generally, it cannot be used directly for planting. The traditional method is to mix it with the soil after natural fermentation. With the continuous expansion of the greenhouse planting area and the introduction of new technologies, in addition to continuing to retain its traditional use method, the sheep manure is fermented and mixed in some kind of plant fiber to implement soilless cultivation application, which has gradually been paid attention to. , because it is basically a kind of regional resource, it is mostly still in an exploratory stage when it is applied to large-scale soilless cultivation, and no mature substrate varieties and technologies have been seen. ...

Problems solved by technology

Because, if you want to develop green organic agriculture, you must first use non-polluting organic fertilizer resources. At present, the solid-state organic fertilizers used in soilless cultivation in my country have many uncertain factors due to their messy sources of fertilizers. The content of components and harmful substances cannot be measured and selected by scientific data and standardization, and it is impossible to test every component. Therefore, it is difficult to unify the standard in the process of mixing and proportioning substrates and fertilizers. It is relatively large, and it can only be operated by experience and feeling when using it. The quality of the agricultural products grown in this way varies greatly

Especially due to the non-uniformity of its raw material sources, the uncertainty of various components contained in it, the possibility of containing harmful substances, and the incompleteness of its nutritional components, and in the whole planting process, it is necessary to add A certain amount of chemical nutrient solution, so the culture substrate selected and used in the implementation of soilless cultivation technology in our country is very irregular, and there is no standard system for ecological soilless cultivation in the true sense. Therefore, this substrate form And the method of use can only be used in a small area in a local area, and its products are naturally impossible to determine on a certain level of standard, and to implement large-scale, standardized and factory production must be further improved and improved. improve
