Seedling culture method for cultivating early-spring strong vegetable seedlings by utilizing sunlight greenhouse

Abstract

The invention discloses a seedling cultivation method for cultivating early-spring strong vegetable seedlings by utilizing a sunlight greenhouse, belonging to the technical field of high-efficiency agriculture cultivation. The method comprises the following steps: in the sunlight greenhouse, performing the longitudinal bedding, wherein the bedding face width is 1.2m and the bedding pit width is 0.3m, so that an overground bedding surface higher than the ground by about 10cm is formed; paving a piece of gardening ground fabric on the bedding surface, then paving a substance, arranging electric hot lines, and placing seedling culture hole tray after fine earth with the thickness of 1cm is coated; according to the proportion that 1kg of a fungus fertilizer is added to every 50L of a Qingfeng seedling culture substance, uniformly mixing the seedling culture substance and the fungus fertilizer to prepare a disease prevention substance; after seedling emergence of about ten days, watering a seedbed once, and then coating dry fine earth with the thickness of about 0.5cm on the surface of the substance. According to the seedling cultivation method, the characteristics of being high overwintering seedling culture safety, low in disease incidence, small in pesticide application quantity, low in seedling culture cost and high in seedling culture quality can be realized.

Description

technical field [0001] The invention relates to a vegetable seedling raising technique, which is a seedling raising method for cultivating early spring vegetable seedlings in deep winter in a solar greenhouse. Background technique [0002] Facility cultivation can provide good environmental conditions for the growth and development of crops, better meet the requirements of crops for environmental conditions (light, heat, water, air), prolong the growing season, thereby obtain high-yield and high-quality agricultural products, and achieve higher economic benefits At the same time, to a certain extent, get rid of the impact of unfavorable climate on agricultural production, improve the ability to resist natural disaster risks, and enhance the stability of agricultural production. The development of my country's agricultural facility cultivation is mainly based on solar greenhouses and plastic greenhouses. The integration and demonstration of current advanced facility cultivati...

Problems solved by technology

Vegetables in facilities are mostly grown and transplanted. Seedlings for off-season production in solar greenhouses and greenhouses, early spring production, and long-season production are all in late winter and early spring (January and February), while late winter and early spring seedlings are the best for vegetable seedlings. The difficulty is that the production is mainly based on the self-cultivation of seedlings by farmers. The quality of the seedlings is poor, and the seedlings often fail to grow. In addition, it takes up a lot of land, takes a lot of labor, and the cost of seedlings is high. The cost of greenhouse control and operation is high, the starting point for seedling cultivation is large, the cost of seedling cultivation is too high, and it is difficult to popularize and apply; some farmers have begun to use commercial vegetable seedlings, but the purchase and transportation costs are high, and the cost of using seedlings is high, and the seedlings purchased long-distance Susceptible to adverse environmental influences, it is difficult to ensure the quality of seedlings

The current supply of facility vegetable seedlings is not compatible with the rapid development of facility cultivation. The lack of facility vegetable seedling production and supply system limits the further improvement of facility vegetable benefits in my country, affects the annual production stubble arrangement of facility vegetables and the improvement of product core competitiveness, and becomes The "bottleneck" problem in the development of the facility vegetable industry needs to be resolved urgently
