Method for preventing successive cropping obstacle of watermelon and seedlings growing and cultivating medium

Abstract

The invention belongs to the technical field of the production of an agricultural matrix, and particularly relates to a method for preventing the successive cropping obstacle of a watermelon and a seedlings culturing and cultivating medium. The matrix comprises the following raw materials by volume percent: 70%-90% of earthworm shit and 10%-30% of vermiculite, wherein the earthworm shit is screened by a screen of 5mm, and the grain sizes of vermiculite are 3-6mm. After the seedlings are cultured by the watermelon seedlings culturing and cultivating medium provided by the invention, the fertilizer application process when the watermelon seedlings are cultured can be completely eliminated, the watermelon germination, and the normal culturing development of the seedlings can be guaranteed. According to the matrix, the watermelon can be cultivated, the watermelon topdressing can be completely or partially eliminated, the use of watermelon successive cropping obstacle-resistant pesticide can be reduced, the labor and the cost can be saved, and the safety quality of the watermelon fruits can be improved.

Description

technical field [0001] The invention belongs to the technical field of new raw materials and formula improvement of cultivation substrates, is an organic component of agricultural substrate production technology, and specifically relates to a seedling-raising substrate for preventing watermelon continuous cropping obstacles, especially the composition and preparation method of the watermelon seedling-raising substrate. Background technique [0002] In recent years, the protected cultivation mode of watermelon crops has developed rapidly, and the planting scale has continued to expand. The continuous cropping obstacles of watermelon protected cultivation have become very serious. Continuous cropping of watermelon itself is forbidden, and diseases will occur in one year of continuous cropping, and it can only be planted after 8 years of crop rotation. Continuous cropping obstacles have seriously affected the production of watermelon and the supply of the market. The practice o...

Problems solved by technology

[0006] Before the present invention, the existing watermelon seedlings and cultivation substrates did not have the function of preventing watermelon continuous cropping obstacles, and there were many deficiencies: often due to the compaction of itself and the underlying soil, poor permeability, poor nutrient balance, buffering, etc. The performance becomes smaller, which is not conducive to the growth of seedlings, and even causes the plants to show symptoms of nutrient deficiency and other physiological diseases, which seriously affects the growth of substrate seedlings and cultivation.
