Additive for relieving chilli autotoxicity and preparation method thereof

Abstract

The invention relates to additive for relieving chilli autotoxicity and preparation method thereof. The additive comprises the following components in percentage by weight: 47.6 percent of pulverized maize straw, 4.8 percent of horse manure and 47.6 percent of water. The preparation method comprises the following steps of: (1) weighing 47.6 weight percent of the pulverized maize straw and uniformly mixing the pulverized maize straws with 47.6 weight percent of the water and 4.8 weight percent of the horse manure so as to ensure that the water soaks the maize straws which is in sufficient contact with the horse manure; (2) putting the uniformly mixed mixture of the maize straws, the horse manure and the water in a plastic-covered tunnel with a day temperature of 25-30 DEG C and a night temperature of 20-25 DEG C to decompose for 50-150 days; during decomposing, turning out the mixture every 5 days and complementing water, wherein during decomposing, the water content is 50-65 percent; and (3) obtaining a decomposed product namely the additive for relieving the chilli autotoxicity. The invention can replace crop rotation and overcome chilli continuous cropping obstacles, is simple and convenient to apply and suitable for a modern vegetable production mode and can avoid pollutions to the environment.

Description

Technical field: [0001] The invention relates to an additive for alleviating the autotoxic effect of capsicum and a preparation method thereof. Background technique: [0002] Pepper is an important solanaceous vegetable, and its vitamin C content ranks first among all kinds of vegetables. According to statistics from the Food and Agriculture Organization of the United Nations, China exported 53,075 tons of pepper in 1997, worth 72.033 million US dollars. At present, the total output of chili in my country ranks first in the world, with an annual output of more than 28 million tons, accounting for about 46% of the world's chili production, and an annual growth rate of 9%. However, there are serious continuous cropping obstacles in pepper. According to the survey, the continuous cropping period in pepper producing areas is generally 5 to 10 years, up to 20 years, the incidence rate is as high as 88%, and the dead plant rate is 38% to 85%. It is also reported that the output...
