Capsicum soilless culture matrix for preventing and controlling insect diseases and preparation method thereof

Abstract

The invention discloses a capsicum soilless culture matrix for preventing and controlling insect diseases and belongs to the technical field of soilless culture. The capsicum soilless culture matrix comprises, by weight, 200-400 parts of turf, 25-80 parts of perlite, 10-25 parts of vermiculite, 10-25 parts of biogas residues, 5-10 parts of wood chips, 2-4 parts of EM composite inocula, 1-5 parts of a trichoderma sp. agent, 15-30 parts of brown coal, 2-8 parts of walnut shell powder, 3-7 parts of husk ash, 1-3 parts of brown sugar, 1-3 parts of gypsum, 10-15 parts of chicken manure, 100-150 parts of cassava slag, 30-65 parts of humus soil, 1-3 parts of carbendazim and 2-5 parts of szechwan Chinaberry fruits. The capsicum soilless culture matrix is rich in nutrients, reduces capsicum insect diseases and provides a good root environment for capsicum growth.

Description

technical field

[0001] The invention belongs to the technical field of soilless cultivation, in particular to a pepper soilless cultivation substrate for preventing and controlling pests and diseases and a preparation method thereof. Background technique

[0002] Capsicum is one of the vegetable varieties generally cultivated in various places in my country. In recent years, with the rapid development of facility planting, the phenomenon of repeated cropping in pepper planting areas has become more and more common. Mild diseases caused by continuous cropping can reduce pepper yields by 20% to 30%, and severe ones can reduce yields by more than 50% or even fail. caused huge economic losses to farmers.

[0003] Capsicum root rot, blight, blight, bacterial blight, root-knot nematode, etc. are very common fungal diseases in pepper production. For many years, chemical control measures have not only failed to curb the rising trend of diseases, Moreover, it also inhibits the bene...
