Problems solved by technology

The use of chemical pesticides with strong anti-pathogen effects on crop Fusarium wilt has the problem of treating the symptoms but not the root cause, and the large-scale use of chemical pesticides is prone to follow-up effects such as drug residues and unfavorable normal growth of crops. It can be seen that the development of crops that can resist Fusarium wilt and other crops diseases, and prevent pesticide residues in food, vegetables, fruits, etc., and organic drugs that can promote the growth of crops are imminent

Abstract

The invention relates to a compound traditional Chinese medicine for preventing and curing crop diseases and a preparation method thereof, solving the problems that the conventional crop diseases of greensickness and the like are difficult to prevent and cure. The compound traditional Chinese medicine comprises the following components in parts by weight: 120-150 parts of radix sophorae flavescentis, 50-70 parts of scutellaria baicalensis, 70-90 parts of fructus cnidii, 40-60 parts of fructus forsythia, 50-80 parts of golden cypress, 50-60 parts of honeysuckle, 40-60 parts of polygonum multiflorum, 50-60 parts of prepared rehmannia root and 40-60 parts of rheum officinale and is prepared in the following steps of: carrying out water adding, soaking, decoction, filtering and extraction. The compound traditional Chinese medicine can be used for effectively preventing and curing greensickness and various conventional diseases of crops, has no environment pollution and residue to the crops and the soil and is beneficial to crop growth.

Description

technical field [0001] The invention relates to a compound traditional Chinese medicine for crops and a preparation method thereof. Background technique [0002] Verticillium wilt is a general term for Fusarium wilt and Verticillium wilt, because Fusarium wilt and Verticillium wilt are easy to mix. Fusarium wilt is known as the "cancer" of crops, and it is the most devastating disease affecting crop production. They harm crops in various forms such as pathogens blocking ducts and producing toxins. The pathogen can also be transmitted through seeds, soil, water flow and diseased residues, so the transmission speed is extremely fast. At the same time, this pathogen can invade and develop diseases in various growth stages of crops, so it is very difficult to control. For example, cotton fusarium wilt, according to statistics from the Plant Protection Institute of the Chinese Academy of Agricultural Sciences, has an area of ​​more than 40 million mu in the country, and an annua...
