Problems solved by technology

[0006] Fumigation disinfectants can not only effectively kill harmful organisms such as fungi, bacteria, and nematodes in the soil, but also kill beneficial organisms in the soil, forming an "ecological vacuum" in the soil. Once harmful organisms invade, they can quickly expand , causing more serious damage

Embodiment 1

[0027] During the fallow period after harvesting the previous crops in summer and autumn, clean the field, evenly spread decomposed organic fertilizer, rotary tillage, and then field irrigation. When the water content of the soil reaches about 60-70%, sprinkle calcium cyanamide granules at an application rate of 10kg / 667m 2 , and then carry out rotary tillage mixing to the soil, the depth is 30cm, and then apply 1,3-dichloropropene EC through special machinery or drip irrigation, and the application rate is 10kg / 667m 2 . After covering the plastic film and sealing it for 20 days, remove the film and open the air for 10 days to complete the soil fumigation and disinfection, and then apply biological fertilizer to the fumigated plot to carry out ecological restoration and activation of the soil.

Embodiment 2

[0029] During the fallow period after harvesting the previous crops in summer and autumn, clean the field, evenly spread decomposed organic fertilizer, rotary tillage, and then field irrigation. When the water content of the soil reaches about 60-70%, sprinkle calcium cyanamide granules at an application rate of 20kg / 667m 2 , and then carry out rotary tillage mixing to the soil, the depth is 25cm, and then apply 1,3-dichloropropene EC through special machinery or drip irrigation, and the application rate is 15kg / 667m 2 . After covering the plastic film and sealing it for 25 days, remove the film and open the air for 8 days to complete the soil fumigation and disinfection, and then apply biological fertilizer to the fumigated plot to carry out ecological restoration and activation of the soil.

Abstract

The invention relates to a high-efficiency soil disinfection and activation technology for preventing and controlling protected vegetable soil-borne diseases. The technology comprises the following operation steps: in a leisure period after harvest of preceding crops in summer and autumn, cleaning fields, performing fertilization and rotary tillage, and then performing field irrigation; when the water content of soil reaches about 60-70%, spraying lime nitrogen granules; performing rotary tillage and soil mixing on the soil; applying 1,3-dichloropropene emulsion oil; performing seal by coverage with plastic film for 20-30 days, then uncovering the film for airing for 7-10 days, completing fumigation disinfection on soil; applying biological bacterial fertilizer to the field after the fumigation disinfection; performing ecological restoration and activation on the soil, so as to establish beneficial microbial flora of the soil. The technology provided by the invention is mainly used forpreventing and controlling the protected vegetable soil-borne diseases caused by pathogenic nematodes, fungi and bacteria. The technology has a notable effect and a long lasting period of preventingand controlling the soil-borne diseases, has a promoting effect on the crop growth, and particularly has a notable effect of root-knot nematode prevention. The soil disinfection technology is economicand high efficient, and has low cost and notable benefits.

Description

technical field [0001] The invention relates to a high-efficiency soil disinfection and activation technology for preventing and controlling soil-borne diseases of vegetables in facilities, in particular to a method of using calcium cyanamide granules and 1,3-dichloropropene emulsifiable oil for fumigation and disinfection and using biological bacterial fertilizer to disinfect soil The ecological restoration and activation technology belongs to the technical field of soil-borne disease and insect pest control. Background technique [0002] In recent years, the area and scale of protected vegetables in my country have continued to expand, and it has become one of the main ways for farmers to increase their income. However, due to the warm and humid environmental conditions of facility cultivation, it is not only beneficial to the growth and development of crops, but also provides conditions for the growth and reproduction of soil-borne diseases and insect pests such as root-k...
