Soil conditioner for controlling konjac erwinia carotovora and preparation method thereof

Abstract

The invention discloses a soil conditioner for controlling konjac erwinia carotovora and a preparation method thereof. The soil conditioner comprises the following raw materials by mass: 10-50 parts of calcium oxide, 5-40 parts of calcium hydroxide, 10-60 parts of potassium sodium silicate, 10-50 parts of sulphur and 5-40 parts of activated clay. The preparation method includes: crushing the raw materials respectively, then weighing and mixing the raw materials evenly in proportion, and then conducting crushing by a jet mill, thus obtaining the finished product. Repeated experiments on the main cultivated varieties akonjac and aalbus indicate that the soil conditioner has a control effect on konjac erwinia carotovora up to 80% or more, and has the advantages of economical efficiency, safety, remarkable control effect and simple use.

Description

technical field [0001] The invention belongs to the technical field of soil conditioner preparation, and in particular relates to a soil conditioner capable of effectively preventing and treating konjac soft rot. Simultaneously, the invention also relates to a preparation method of the soil conditioner. Background technique [0002] Konjac is the general term for plants of the genus Amorphophallus Blume in the family Araceae. In cultivation, it belongs to the potato and taro crops. There are about 163 species of Konjac plants in the world, and more than 20 species are edible. There are 21 species of konjac plants in China, 11 species in Yunnan, and 5 species that are edible. The main varieties of konjac cultivated in China are flower konjac (Akonjac) and white konjac (Aalbus). In recent years, the planting area is about 300,000 mu. The annual planting area in Yunnan Province is about 80,000 to 100,000 mu, of which about 60,000 mu are planted in Fuyuan County. In China,...
