Novel culture substrate

Abstract

The invention relates to a culture substrate, which is prepared from insect mature generated by insects and organic matters; particularly, the organic matter includes decomposed crop stalks and / or coconut husk; preferably, the crop straws include corn stalks and / or wheat stalks. In the culture substrate, the insect mature and the decomposed crop stalks can achieve a cooperated effect on the growthof the crops, so that the technical problems of short nutrient effect duration period, long seedling restoration time, poor plant root system development, low yield and the like due to utilization ofcrop stalk utilization in the prior art can be solved.

Description

technical field [0001] The invention relates to a novel cultivation substrate. Background technique [0002] In modern agricultural production, soilless cultivation technology has been more and more widely used. Soilless cultivation can effectively cut off the transmission of disease sources and insect sources, avoid continuous cropping obstacles, save water and fertilizer, and are not restricted by the environment and site, etc. advantage. At the same time, the agricultural products produced by soilless cultivation are more in line with the standard of green food. [0003] Soilless cultivation technology originated in Europe and the United States. With the development of agricultural technology and the increasingly prominent problems of soil salinization, continuous cropping obstacles, and land resource shortages in my country, soilless cultivation technology in China has begun to rise. The difference lies in the choice of substrate types. In general, European and American...

Problems solved by technology

Although corn stalks are widely used, the actual utilization rate is less than half

[0007] Although crop straw contains a large amount of organic matter and trace elements for plant growth, and is easy to obtain and low in price, it is a rare raw material for cultivation substrate, and it is also used as a source of cultivation substrate in practice, but crop straw is in the There are still some problems to be solved in terms of substrate utilization. For example, the main method of developing corn stalks as a cultivation substrate is to mix straw with traditional organic fertilizers such as chicken manure, manure (cattle and sheep manure, etc.), and then add some auxiliary materials for crop cultivation. Cultivation and production can be popularized, but there are also serious problems, mainly because most of this type of substrate has short nutrient duration, long seedling slowing time, insufficient attention to plant root development, and low yield.

In addition, raw materials such as chicken manure, cattle and sheep manure, etc. will leave a large amount of antibiotics, salt ions and other substances in the production process, which will seriously affect the yield and quality of crops.

Moreover, these organic fertilizers need to go through a strict fermentation process before use. If they are not fully decomposed, they will cause fatal damage to the crops produced.
