Biological seedling raising and cultivating matrix containing antagonistic crop diseases

Abstract

A biological seedling raising and cultivating matrix containing antagonistic crop diseases is prepared from, by weight, 17-19 % of cow dung, 5-15 % of urea formaldehyde resin foam particles, 13-40 % of straw, 8 % of cow urine, 14-20 % of wood fiber and 0.01% of trichoderma. The invention further discloses a processing method of the biological seedling raising and cultivating matrix containing the antagonistic crop diseases. The processing method comprises the steps that the straw is rubbed, the straw, the cow dung and cow urine are fermented, and a fermenting product is mixed with the urea formaldehyde resin foam particles, the wood fiber and the trichoderma. The biological seedling raising and cultivating matrix has the advantages that produced urea formaldehyde resin foam is weakly acid, products can be regulated to be in a meta-acid range, and accordingly the problem that the cow dung and urine fermentation materials are alkaline and are suitable for trichoderma survival and propagation expanding is solved. Most of wood fiber is completely decomposed after two months when being used for the cultivating matrix, the straw framework effect is gradually weakened under trichoderma decomposition, difficult breathing of crop root systems is caused, a framework function of the urea formaldehyde resin foam particles is kept at least two years, and accordingly long-term plant growth is ensured.

Description

[0001] Technical field: [0002] The invention relates to the technical field of cultivation and seedling-raising substrates, in particular to a biological seedling-raising and cultivation substrate containing crop diseases resistant. [0003] Background technique: [0004] In order to reduce the spread of diseases, farmers' scattered cattle raising to intensive cattle raising has become a project strongly supported by the National Law Reform Commission in recent years, and intensive cattle raising, including dairy and beef cattle breeding, requires a bed-bed farming model, which must be cleaned every day A mixture of cow dung and cow urine, an adult cow excretes 20-30kg per day, and urinates about 10kg. Such a large amount of manure is a difficult problem for every farm to deal with. In the face of a large amount of cow dung and cow urine mixture produced every day, because It has a certain fluidity, so it is not easy to transport, what's more, it is washed with water, forming...

Problems solved by technology

Among them, the application of antagonistic microorganisms in plant disease biocontrol has attracted much attention. Trichoderma spp. is recognized as having the best biocontrol activity, but poor survival ability
