Embodiment 1

[0027] The method for rapid prevention and treatment of facility soil continuous cropping obstacles comprises the following steps:

[0028] (1) Hidden pipe system: the material of the hidden pipe is made of plastic corrugated pipe, outsourced with non-woven fabric, the buried depth of the hidden pipe is 65cm, and the spacing is 6m;

[0029] (2) Soil pre-treatment: plow the facility soil to a depth of 15-30cm, and then apply 21.5kg / hm 2 Soil structure conditioner and fully irrigate until the soil water content reaches 67.5% of the field water capacity;

[0030] (3) High-temperature stuffy shed and underground pipe drainage: the time of stuffy shed needs to be during the summer crop change period, and the time of stuffy shed is 35 to 75 days; In the evening, to prevent irrigation from destroying the accumulation of soil temperature, the irrigation volume is 55mm / time;

[0031] (5) Microbial compound fertilizer: After the stuffy shed is over, ventilate and ventilate until the s...

Embodiment 2

[0040] The method for rapid prevention and treatment of facility soil continuous cropping obstacles comprises the following steps:

[0041] (1) Concealed pipe system: the material of the concealed pipe is made of plastic corrugated pipe, outsourced with non-woven fabric, the buried depth of the concealed pipe is 60cm, and the spacing is 5m;

[0042] (2) Soil pretreatment: plow the facility soil to a depth of 15-30cm, and then apply 20kg / hm 2 Soil structure conditioner and fully irrigate until the soil moisture reaches 65% of the field capacity;

[0043] (3) High-temperature stuffy shed and underground pipe drainage: the time of stuffy shed needs to be during the period of summer crop change, and the time of stuffy shed is 35 days; To prevent irrigation from destroying the accumulation of soil temperature, the irrigation volume is 50mm / time;

[0044] (5) Microbial compound fertilizer: After the stuffy shed is over, ventilate and ventilate until the soil temperature is lowered...

Embodiment 3

[0048] The method for rapid prevention and treatment of facility soil continuous cropping obstacles comprises the following steps:

[0049] (1) Concealed pipe system: the material of the concealed pipe is made of plastic corrugated pipe, outsourced with non-woven fabric, the buried depth of the concealed pipe is 70cm, and the spacing is 7m;

[0050] (2) Soil pretreatment: plow the facility soil to a depth of 15-30cm, and then apply 25kg / hm 2 Soil structure conditioner and fully irrigate until the soil moisture reaches 70% of the field capacity;

[0051] (3) High-temperature stuffy shed and underground pipe drainage: The time of stuffy shed needs to be during the summer crop change period, and the time of stuffy shed is 75 days; To prevent irrigation from destroying the accumulation of soil temperature, the irrigation volume is 60mm / time;

[0052] (5) Microbial compound fertilizer: After the stuffy shed is over, ventilate and ventilate until the soil temperature is lowered. Whe...

Abstract

The invention provides a method for rapidly preventing and treating successive cropping obstacles of greenhouse soil. The method comprises the steps of arrangement of a closed conduit system, pretreatment of the soil, high-temperature greenhouse closing, closed conduit drainage, fertilization, application of EM rejuvenation liquid and the like. According to the method, with closed conduit drainage as a main measure and high-temperature greenhouse closing as an auxiliary measure, an soil improvement agent and an microbial agent are applied, a physical method, a chemical method and a biologic method for prevention and treatment of the greenhouse soil are organically combined, the salt content of the greenhouse soil can be rapidly lowered, soil-borne diseases can be effectively removed, and the physicochemical property of the soil can be effectively improved.

Description

technical field [0001] The invention belongs to the field of agriculture, and particularly relates to a method for rapidly preventing and controlling soil continuous cropping obstacles in facilities, which can rapidly reduce the salinity of soil in facilities, effectively remove soil-borne diseases and improve the physical and chemical properties of soil. Background technique [0002] Facility cultivation has a positive effect on the off-season and cross-regional cultivation of vegetables and some other economic crops. my country’s current facility cultivation technology has been widely promoted, and it has accounted for 70% of the world’s total facility cultivation area, making it the largest facility cultivation area in the world. s country. However, while protected cultivation has achieved huge economic and social benefits, it has caused many adverse effects on the soil ecological environment, including secondary salinization of soil, imbalance of soil nutrients, serious s...
