Soil conditioner for pepper planting land and preparation method thereof

Abstract

A soil conditioner for pepper planting land in the technical field of pepper planting disclosed in the scheme includes, by weight parts, 26-37 parts of pine bark, 73-95 parts of attapulgite clay, 0.8-1.2 parts of EM bacteria, 28-35 parts of fermented chaff, 23-37 parts of grass carbon, 37-52 parts of vinegar residue and 15-18 parts of tobaccos. During the preparation, a preparation method includesthe first step of placing the pine bark and the tobaccos in water for soaking and fermentation for 15-20 d; the second step of first wetting the chaff to a water content of 50-60%, and then applyinga layer of urea on each layer of chaff which is 8-12 cm thick, wherein the urea adding amount is 0.35-0.65% of the dry chaff; performing airtight fermentation for 60-70 d, to obtain fermented chaff; the third step of mixing the fermented chaff, the grass carbon, the vinegar residue, the attapulgite clay and the soaked pine bark and tobaccos to obtain a mixture, and sealing and fermenting the mixture for 15-20 d; and the fourth step of mixing the fermented mixture and the EM bacteria to obtain the soil conditioner for the pepper planting land. The soil conditioner in the scheme can remarkably make an improvement on the problems of autotoxicity caused by continuous pepper production and the deterioration of soil physical and chemical shape.

Description

technical field [0001] The invention belongs to the technical field of pepper planting, and in particular relates to a soil conditioner for pepper planting land 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. At present, the total output of chili in my country ranks first in the world, but there are serious obstacles to continuous cropping of chili. 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 of peppers with repeated cropping will drop by 10% to 15% in one year, 20% to 30% in 2 years and 30% to 50% in 3 years. [0003] The obstacle of continuous cropping has become a bottleneck restricting the sustainable development of pepper industry. The reasons for...
