Abstract

The invention belongs to the technical field of agricultural planting, and particularly relates to a culture medium capable of improving salt tolerance of chilies and a preparation method of the culture medium. The culture medium is prepared from following components in parts by weight with a scientific method: cow dung, wormcast, silkworm excrement, mushroom dregs, rice bran, sawdust, biogas residues, nitrogenous fertilizer, phosphorus fertilizer, potassium fertilizer, a complex microbial agent and a pyrroloquinoline quinone solution with concentration of 200-400 nmol/L. The culture medium contains multiple organic materials, fertilizer and microorganisms, the pyrroloquinoline quinone solution is added in a preparation process, so that development of chili seedlings and formation of strong seedlings can be promoted, the salt tolerance index, the photosynthetic characteristics and the enzymatic activity of the transplanted chilies are obviously improved, which indicates that the salt tolerance of the chilies is certainly improved and growing ability of the chilies on the salinization land can be enhanced.

Description

technical field [0001] The invention belongs to the field of agricultural planting, and in particular relates to a culture medium for improving salt tolerance of pepper and a preparation method thereof. Background technique [0002] Capsicum is an important solanaceous vegetable with rich nutrition. Its vitamin C content is 5 times that of tomato, 20 times that of eggplant, and the content of carotene is 7-15 times that of tomato and 20-35 times that of eggplant. Pepper is one of the vegetable crops with the largest planting area in my country. In 1997, the total output of pepper in my country ranked first in the world, with an annual output of 28 million tons, accounting for about 46% of the world's pepper production. The planting area and economic value of pepper have surpassed cabbage to become the first A large vegetable crop. At present, due to the irrational use of fertilizers and other reasons in the pepper planting process, the soil in the pepper planting area is sal...
