Problems solved by technology

[0004] In order to solve the problems in the prior art of using half-soil and half-substrate to continuously plant strawberries for more than 2 years, soil diseases and insect pests will become serious year by year, the growth of strawberries will become weaker year by year, the dead seedling rate of strawberry plants will increase year by year, the quality of strawberry fruit will decrease year by year, and the yield will decrease year by year. The invention provides a method for repairing the cultivated semi-soil and semi-substrate, which can effectively repair the substrate, optimize the physical and chemical properties of the substrate, balance the nutrients in the substrate, and solve the problems of secondary salinization and a large amount of soil-borne pathogenic bacteria accumulation.

Embodiment 1

[0027] According to the restoration method of half-soil and half-substrate cultivation soil, a) spread plastic film on the wall of the trapezoidal cultivation tank, fill the lower part of the tank with nutrient soil and fill the upper part with matrix; b) evenly add disinfectant, 50-70g, into the cultivation tank m -3 Spraying and watering makes the upper matrix in the cultivation tank completely settle; c) cover with film for 7-10 days, remove the film and open air; d) detect residues in germination test; e) add soil reducing agent after no residues, that is, after the restoration is completed half-soil and half-substrate cultivation soil.

[0028] Experimental example 1 Evaluation of the use effect of the restoration method of half soil and half matrix cultivation soil

[0029] In order to effectively judge the restoration effect of the half-soil half-matrix cultivation soil restoration method of the present invention, Beijing Jiexi Agricultural Science and Technology Co., Ltd. carried out matrix soil-borne pathogenic microorganisms (Fusarium, Phytophthora and nematodes) ), and follow-up surveys on strawberry growth indicators during the growth period, in order to objectively and comprehensively evaluate the impact of different disinfection methods on strawberry production.

[0030] According to the restoration method of the half-soil and half-matrix cultivation soil in Example 1, the matrix was repaired.

[0031] Before restoration and after restoration, 200g of substrate in the blank area and the treatment area were collected respectively, and the samples were sealed for the isolation and detection of Fusarium ...

Abstract

The invention provides a repair method for semi-soil and semi-matrix cultivating soil. The method comprises the following steps: filling the lower part of a cultivating groove with nutritional soil; filling the upper part with a matrix; adding a disinfectant into the cultivating groove uniformly; adding a film to cover the cultivating groove for 7-10 days; uncovering the film to ventilate; detecting residues by means of a germination test; adding a soil reducer and the like to prepare the semi-soil and semi-matrix cultivating soil. The method can repair the matrix effectively, optimizes the physical and chemical characteristics of the matrix, balances nutrients in the matrix and solves the problems of secondary salinization and massive accumulation of soil-borne pathogenic bacteria and thelike. The method can reduce the incidence rate of the soil-borne diseases effectively and promote growth of plants positively.

Description

technical field [0001] The invention belongs to the technical field of soil pollution control and environmental restoration, in particular to the restoration field, and mainly relates to a matrix restoration method, in particular to a half-soil half-matrix cultivation soil restoration method. Background technique [0002] In recent years, with the improvement of agricultural productivity, vegetable substrate cultivation technology is gradually being recognized by the majority of vegetable farmers for its advantages of saving labor and labor, saving water and fertilizer, high quality and high efficiency, environmental protection and less pollution, and avoiding continuous cropping obstacles. Substrate cultivation technology refers to a cultivation method in which a solid substrate (medium) is used to fix the plant root system and absorb nutrient solution and oxygen through the substrate. The semi-substrate cultivation technology was independently developed by the Beijing Chan...
