Problems solved by technology

Most of the above commonly used fumigants are highly toxic and high-residue pesticides, which are extremely harmful to operators and the environment, and seriously threaten the safety of vegetables.
And the operation is relatively complicated, and the film needs to be covered and finally removed for ventilation after application. The entire treatment cycle lasts for more than 15 days, and the comprehensive cost is as high as 1500-2000 yuan / mu

Embodiment 1

[0023] Before the ginger is harvested in the current year or planted in the second year, clean up the remaining plants in the plot, level the soil, and adjust the mat; use a plastic container to prepare a chlorine dioxide disinfectant with a concentration of 10g / l; press the mat Irrigate 20 tons / mu of clear water into the plot, and the thickness of the soil soaking layer is 25cm; while watering, use a flow meter to evenly add 240L / mu of disinfectant to the irrigation water, and enter the soil along with the irrigation water; the irrigation is completed After that, let it dry naturally for 2 days, then you can plant it with rotary tillage and fertilization.

[0024] Chlorine dioxide disinfectant includes two solid substances, A component and B component, which are separately sealed and packaged. The A component and B component are made of the following raw materials in mass percentage:

[0025] A component: sodium chlorite 60%, desiccant 40%;

[0026] B component: solid organi...

Abstract

The invention discloses a ginger field planting soil disinfection method. The method includes steps: after gingers are harvested in the current year or before plantation of the gingers in the next year, clearing residual plants in a land plot, leveling soil and adjusting ridges; irrigating the soil with irrigation water containing a chlorine dioxide disinfector, wherein the concentration of the chlorine dioxide disinfector entering the soil is 120-150mg / l. By completely taking disinfection advantages of high efficiency, quickness, broad spectrum and freeness of residues of chlorine dioxide and unique advantages of simplicity and convenience in operation, low cost, short cycle and environment friendliness in use, the ginger field planting soil disinfection method has the advantages of remarkable disease control effect, low cost, simplicity and convenience in operation and freeness of pesticide residues, hazards and environmental pollution and has high popularization value and promising application prospect in development of ecological efficient agriculture.

Description

technical field [0001] The invention relates to a soil disinfection method, in particular to a soil disinfection method for ginger field planting. Background technique [0002] Soil-borne diseases are based on the long-term accumulation of harmful fungi, bacteria, nematodes and viruses in the soil caused by crops planted in succession. When conditions are suitable, they multiply and infect from the roots or necks, such as fusarium wilt, root rot, Diseases such as sheath blight and blight can cause plant death and yield reduction or even extinction. This disease has become more and more serious in ginger cultivation in recent years. [0003] Soil disinfection is a fast and effective technical method for soil remediation and solution to continuous cropping soil-borne diseases, which is widely used in the world. In my country, soil chemical fumigants are a common method to solve soil-borne diseases. The operation method is to apply chemical agents to the soil, and let the che...
