Method for raising watermelon seedlings in solar greenhouse

Abstract

The invention discloses a method for raising watermelon seedlings in a solar greenhouse. The method comprises the following steps that 1, a watermelon variety is selected; 2, a stock variety is selected; 3, a mycorrhizal fungi seedling raising medium is prepared and seedling raising containers are selected; 4, seeds are preprocessed, sprout and are sowed and bred; 5, grafting is performed; 6, normal seedling management is performed after grafting and survival; 7, after grafted seedling grow normally, transplantation and field planting are performed in the solar greenhouse. The method for raising the watermelon seedlings in the solar greenhouse has the advantages that the seedlings are raised in the mode that mycorrhiza inoculation, grafting and seedling raising are combined, the soil nutrient absorbing ability of watermelon root systems can be improved, fertilizer input is reduced, the cost is reduced, the strong seedling index can be improved by 30% or above, the stress resistance and disease resistance are greatly strengthened, a mature period is advanced for 7 days or more, successive cropping obstacles of the solar watermelon greenhouse can be completely overcome, economic benefits of watermelon planting in the solar greenhouse are remarkably increased, and the enthusiasm of planting farmers is further improved.

Description

technical field [0001] The invention relates to the technical field of planting agricultural products, in particular to a method for raising seedlings of watermelons in a solar greenhouse. Background technique [0002] The traditional cultivation technology of watermelon planting in solar greenhouse is to use the seedling container to grow seedlings directly and then transplant them. The seeds are directly sown in the seedling containers. Poor disease resistance, relatively late maturity, and the continuous cropping disease rate is as high as 50-60%, which seriously affects the production efficiency and the enthusiasm of growers. Contents of the invention [0003] The purpose of the present invention is exactly at the defect in the above-mentioned prior art, provides a kind of seedling raising method of solar greenhouse watermelon, and its purpose is to change traditional solar greenhouse watermelon seedling raising method, utilizes the mode that mycorrhizal inoculation an...
