Embodiment 1

[0018] Test drug

[0019] Bacillus subtilis, amino oligosaccharin composition

[0020] Soil sample for test

[0021] Soil samples were collected in protected areas in Beijing, where nematodes and diseases are serious all the year round, and the soil from the plow layer was taken and passed through a 2mm sieve, and mixed well for later use. After analysis, the soil water content is 18.76%, pH6.48, soil organic matter content is 4.5%, NH 4+ -N 18.1mg / kg, NO 3- -N 118.8mg / kg, available phosphorus 552.8mg / kg, available potassium 666.1mg / kg, belonging to sandy loam.

Abstract

The invention discloses a mixture for preventing and treating a soil-borne disease and protecting plants from cold. The composition is a bacillus subtilis and amino-oligosaccharin composition. After the composition is mixed with a wetting agent, a thickening agent, a dispersing agent and a carrier, the mixture can be used as a drug for effectively preventing and treating the soil-borne disease. The composition can effectively kill harmful germs in soil and improves cold resistance of crops, and is used in crops such as vegetables, strawberries, flowers, melons, nursery gardens, orchards, tea gardens, graperies, woods and Chinese herbal medicines.

Description

technical field [0001] The invention relates to a composition for preventing and controlling crop diseases and improving crop cold resistance, in particular to a composition for preventing and controlling soil-borne diseases and improving crop cold resistance. Background technique [0002] In the past ten years, with the adjustment of the agricultural planting structure, protected cultivation has developed rapidly in my country, and the national protected area has exceeded 2 million hectares. As an important agricultural measure to increase farmers' income and transform from traditional agriculture to modern agriculture, protected cultivation in China will continue to develop in the future, and the crops cultivated will also change from the current vegetables and strawberries to flowers, melons, and fruit trees. , Nursery, Chinese herbal medicine and other directions. The development of protected areas also provides a suitable environment for the development of soil-borne d...
