Nutritional soil for raising seedlings of physalis alkekengi in greenhouse and application of nutritional soil

Abstract

The invention relates to nutritional soil for raising seedlings of physalis alkekengi in a greenhouse and application of the nutritional soil. The application soil provided by the invention comprises the following components in mass percentage: 92.5%-92.7% of turf soil, 6.9%-7.1% of a biological organic fertilizer and 0.3-0.5% of a seedling strengthening agent. According to the nutritional soil provided by the invention, the turf soil is used as a soil medium, and the biological organic fertilizer and the seedling strengthening agent are used for matching, thereby providing nutritional space for raising the seedlings, enabling the growth of the seedlings to be robust, realizing strong disease resistance, enabling crops to appear on the market in advance and increasing the income by 3000 yuan per mu; and the cost is relatively low, which is saved by above 50% in comparison with conventional seedling raising cost.

Description

technical field [0001] The invention relates to a nutrient soil for growing seedlings, in particular to a nutrient soil for raising seedlings of mushrooms in greenhouses and an application thereof. Background technique [0002] The research on the nutrient soil for seedling cultivation began in the mid-1980s. Beijing, my country introduced the precision seeding production line for plug seedling cultivation from the United States and the European Community, and it has been put into factory and commercial production in the suburbs of Beijing. [0003] The current level of modernization in our country is relatively low. When preparing soilless seedling substrates, it is necessary to adapt measures to local conditions, choose raw materials that are rich in resources, cheap, and can satisfy root nutrition, water and air supply as substrates. According to research, the composite matrix prepared from cottonseed husks, pig manure, slag ash, furfural slag, vermiculite, etc. that have...

AI Technical Summary

Problems solved by technology

The existing technology for growing seedlings in greenhouses is labor-intensive, high in production costs, and takes up a large area for seedlings. The materials for raising seedlings are relatively conventional and can be used in a wide range, but they are not specific, so they are not suitable for large-scale promotion and application, and cannot meet the needs of growers.
