Method for floating breeding of cabbage seedling

Abstract

The invention discloses a method for breeding of cabbage seedlings. An artificially prepared substrate is adopted to breed cabbage seedlings in a rainproof greenhouse, harm of diseases, pests and weeds which can be spread in soil can be avoided, various effects on the cabbage seedlings caused by difficult-to-control defects of physical and chemical properties of soil can be eliminated completely, normal growth of the cabbage seedlings can be ensured, environmental conditions of the nutrients, temperature, moisture and light required for growth of the cabbage seedlings can better provided, adverse effects of dramatic changes in the environmental conditions on the seedling breeding process can be avoided, smooth breeding of the cabbage seedlings can be ensured, and commercialized and intensified scale production of the cabbage seedlings can be realized. Large quantities of uniform, delicate, disease-free and robust cabbage seedlings can be cultivated in a short term, the breeding period of the seedlings can be shortened, the uniformity of transplanted seedlings can be improved, concentrated transplanting of the cabbage seedlings in a contiguous region in the best seasons can be ensured, the consistency and uniformity of growth of cabbage plants can be improved, and a good foundation can be laid for balanced and efficient production of cabbages.

Description

technical field [0001] The invention belongs to the technical field of cabbage seedling cultivation, in particular to a method for floating cabbage seedling cultivation. Background technique [0002] Existing methods of growing cabbage seedlings cannot be separated from the shackles of the soil and the adverse factors of external natural conditions. Due to the harm of diseases, insects, and weeds carried by the soil, it is very easy to cause diseases and insect pests in the seedlings, underdeveloped root systems, low uniformity, and resistance. Poor reversibility, slow seedling return after transplanting, low survival rate, and unobvious economic benefits. Contents of the invention [0003] The invention provides a method for growing seedlings of cabbage by floating, aiming to solve the problem that the existing method of raising seedlings of cabbage cannot be separated from the shackles of the soil and the unfavorable factors of external natural conditions. It is easy to...
