Abstract

The invention discloses a compound fungicide specially used for rice breeding. The compound fungicide is prepared from the following raw materials in parts by weight: 30-45 parts of an effective component, 10-25 parts of additives and 50-85 parts of filler, wherein the effective component is a mixture of plant polysaccharides, radix astragali seu hedysari, cinnamon essential oil, cerium complexesand matrine, wherein the weight ratio of the plant polysaccharides to the radix astragali seu hedysari to the cinnamon essential oil to the cerium complexes to the matrine is equal to (2-10) to (1-4)to (2-8) to (9-20) to (1-3). The compound fungicide, provided by the invention, specially used for rice breeding is good in fungicidal property, has little damage to rice, and is high in breeding yield.

Description

technical field [0001] The invention relates to the technical field of rice breeding, in particular to a special compound fungicide for rice breeding. Background technique [0002] Rice is an annual gramineous plant, and the fruit it bears is paddy, which is called rice or rice after shelling. In addition to being edible, it can also be used as a raw material for wine making and sugar refining. Rice husks and rice straws also have many uses. Among the rice planted in my country, the hybrid rice planting area accounts for 57% of the total rice area, and the hybrid rice seed production area is 180,000 hm 2 about. The quality of hybrid rice seeds is the basis for realizing high-quality, high-yield and high-efficiency rice production, and the production level of hybrid rice seeds is directly related to my country's food security. [0003] Although the research on rice breeding has progressed rapidly in recent years, in the process of rice breeding, the yield of its seed produc...
