Method for improving soil physical and chemical properties of continuous cropping crops in greenhouse

Abstract

The invention relates to a method for improving soil physical and chemical properties of continuous cropping crops in a greenhouse. Under sunlight illumination, the temperature and humidity of the greenhouse are rapidly increased, the air temperature and the ground temperature can reach 60 DEG C and 40 DEG C, and the temperature increase range is about 10-20 DEG C, which is maintained for a certain period of time so as to kill soil bacteria and improve a soil structure; the community structure of plant root microorganisms is improved, beneficial bacteria becomes dominant strains, and a soil environment is effectively improved; soil salt accumulation is reduced, soil physical and chemical properties are improved, and soil nutrients are balanced; an enzyme activity is reduced; after water pouring high temperature greenhouse suffocation treatment, a certain repairing effect on greenhouse continuous cropping soil is achieved, and the method has a certain promoting effect on the growth of crops of second stubble, increases crop yield and improves economic benefits.

Description

technical field [0001] The invention relates to the technical field of agriculture and forestry technology, in particular to a method for improving soil physical and chemical properties of greenhouse continuous cropping crops. Background technique [0002] Facility agriculture is one of the important industries for farmers to increase their income. However, farmers blindly fertilizing in pursuit of high-yield yields and planting the soil year after year will reduce the content of soil organic matter and eventually destroy the aggregate structure of the soil. Because of the long-term multi-crop cultivation and utilization, the greenhouse continuous cropping soil has less rainwater leaching, which creates favorable conditions for the spread of diseases, and the long-term single planting mode will affect the physical and chemical properties of the soil, thereby affecting crop yields. [0003] Watermelons, strawberries, etc. are more and more popular as high-efficiency products....

Problems solved by technology

[0002] Facility agriculture is one of the important industries for farmers to increase their income, but farmers blindly fertilize in pursuit of high-yield output measures and soil continuous planting will reduce the content of soil organic matter and eventually destroy the aggregate structure of the soil

Because of the long-term multi-crop cultivation and utilization, the continuous cropping soil in the greenhouse has less rainwater leaching, which creates favorable conditions for the spread of the disease, and the long-term single planting mode will affect the physical and chemical properties of the soil, thereby affecting the crop yield.

[0003] Watermelons, strawberries, etc. are more and more popular as high-efficiency products. Due to the high intensity of protected cultivation and the herd mentality of farmers, continuous cultivation throughout the year has resulted in serious continuous cropping obstacles for crops, strawberries, and other high-efficiency crops. The germination rate is reduced, the germination is slow, it is difficult to unearth, or the growth is slow after unearthed, the seedlings are easy to die at the seedling stage, the leaves turn yellow, easy to disease, wither and die, and the yield and quality decline, etc.

[0004] In view of the above problems, most of the existing technologies use external application of drugs and fertilizers to kill diseases and insect pests and increase soil nutrients, but the physical and chemical properties of the soil cannot be improved from the root cause, and the addition of various chemical agents will also seriously affect crops. quality and food safety
