Problems solved by technology

In the soilless cultivation technology disclosed in the prior art, most of the plug seedling substrates adopt a composite substrate with peat as the main raw material, but because peat is a non-renewable resource, large-scale mining will cause ecological environment damage, and the cost is high; in addition , peat, mushroom dregs and other substrates have poor water retention and low water use efficiency, which is more prominent in summer seedling cultivation. The increase in the number of water sprays not only increases the labor cost, but also reduces the aeration of the root system and prolongs the growth of the root system. Seedling cycle; the fertilizer supply for plug seedlings is mainly sterilized chicken manure, and chemical fertilizers are sprayed on the leaves from time to time during the growth of seedlings. This method cannot meet all the fertilizers required for seedling growth, and requires higher technology and more more labor force

Abstract

The invention discloses a water-saving and fertilizer-holding seedling culture substrate, which is prepared by compounding vermiculite and water retention agents in certain proportion, wherein the vermiculite serves as a base material; and the water retention agents have different particle sizes and fully absorb high-concentration fertilizers. The invention also relates to a method for preparing the substrate and the method for performing vegetable plug seedling culture by using the substrate. The seedling culture substrate and the method for performing the vegetable plug seedling culture have the advantages that: seedlings are watered only with clear water in a seedling culture period, so seedling culture procedures are greatly simplified, labor efficiency can be improved by 0.5-1 time, the seedlings are grown fast and have developed root systems, the seedling culture period is shortened by 5 to 7 days, fresh water and turf resources can be saved and the cost is reduced by 20 to 30 percent.

Description

technical field [0001] The invention relates to a seedling raising substrate and its application in vegetable plug seedling raising, belonging to the technical field of soilless cultivation. Background technique [0002] With the rapid development of protected horticulture, soilless cultivation technology and industrial plug seedling technology are being promoted and applied on a large scale, and have become a core technology to promote the development of my country's vegetable industry, which has played a huge role in promoting the increase in production and efficiency of protected agriculture. effect. The selection of seedling substrate and supporting cultivation technology is an important content of industrial plug seedling technology.
