Soilless culture medium and method for growing seedlings of sweet watermelon

Abstract

The invention discloses a soilless culture medium and method for growing seedlings of sweet watermelon. The soilless culture medium is made from, by mass, 5-15 parts of peat, 5-15 parts of vermiculite, 10-20 parts of river sand, 10-20 parts of mushroom dregs, 15-25 parts of sawdust, 20-30 parts of crop stalks, and 2-8 parts of a supplementary element composition. The soilless culture method comprises crushing peat and crop stalks into particles 1-5 mm in size, mixing the particles with vermiculite, river sand, mushroom dregs and sawdust to obtain a mixed medium, covering the medium with a breathable reticular covering after inoculation, carrying out fermenting, soaking watermelon seeds to accelerate germination, spraying little water to the medium in fog form so that the medium is moist, carrying out seeding, and carrying out field planting when seedlings grow three leaves and one shoot or grow four leaves and one shoot. Soil culture herein helps effectively solve the contradiction ofwater, air and nutrient supply difficult to solve in traditional soil culture, allows crop roots to be put under most suitable environmental conditions, soil-borne disease and pest damage is avoided,soil contamination is eliminated, and survival rate of raised seedlings of sweet watermelon is increased.

Description

technical field [0001] The invention relates to the technical field of watermelon planting and preparation, in particular to a soilless culture substrate and method for growing watermelon seedlings. Background technique [0002] Watermelon is a summer consumer fruit rich in various minerals and vitamins. It is also a major agricultural crop. The watermelon planting method has been using soil cultivation for many years. The investment in soil cultivation is small. The nutrients that plants absorb mainly come from the nutrients in the soil. The roots of soil cultivation crops live in the soil layer with good buffering effect. , this soil layer is full of water solution and air. The water and nutrients needed by crops can be absorbed through the soil through the roots. The soil can not only support plants and provide an environment for root growth, but also continuously provide nutrients, water and oxygen for crop roots to absorb .The water and dissolved salt in the soil pores...

Problems solved by technology

However, because soil cultivation is carried out in an open environment, it is in contact with the external environment to a certain extent, and is easily attacked by soil pathogens and pests, which greatly reduces the survival rate of watermelon seedlings.
