How to deal with obstacles to continuous cropping in greenhouses

Continuous crop obstacles have become the key technical problem that restricts the sustainable development of solar greenhouses. The damage from the old vegetable area to the new vegetable area is expanding year by year, resulting in a significant decline in crop yield and quality. The current measures and measures taken in production can be summarized into the following three categories. First, adapt to cultivation method Enhanced resistance: selection of disease-resistant and salt-tolerant varieties and implementation of seedling grafting and root-changing cultivation are all very effective methods for production. 2. Implement crop rotation: Crops of different families will be arranged for rotation at intervals of 3 to 5 years. 3. Chemical treatment: Mix 1000 times solution of Apollo with 1000 times solution of avermectin, induce spraying or rooting to prevent soil-borne diseases; spray with 33 ml/m2 of biological agent to prevent and cure Root knot nematode in the soil. 4. Soilless cultivation: The rice husk, peat, and dried chicken manure were blended into a nutrient soil in a ratio of 2:1:1 and drip-irrigation was conducted in a harmless manner. Organic matter can use 2 growing seasons. Second, the direct improvement of the soil law 1. Change soil method: the use of high-quality fertile soil in the field to replace the solar greenhouse surface 3 to 4 cm soil layer, can effectively reduce the hazards of continuous cropping obstacles. 2. High-temperature disinfection method: After 6 to 8 months of pulling the crops from the previous crops, apply 70-80 kg of lime nitrogen per mu, crushed 500-1000 kg of wheat straw, and rotate tillage and leveling. Seal the greenhouse membrane, cover the membrane, and then apply water. After 15 to 20 days of exposure to high temperature in the sun, the greenhouse will be ventilated and the plastic film will be removed and dried for 5-7 days. Fertilizer and soil preparation will be applied. If we can use 500-1000 times of avermectin 500 ml per plant after the planting of the crop is slow, the effect of preventing and controlling soil-transmitted diseases and insect pests is better. 3. Uncovering film leaching leisure law: in the summer to remove the film, to leave the field or planting open field crops, so that the sun fully exposed to the greenhouse soil, so that heavy rain to fully wash the salt in the soil, can effectively restore the soil. 4. Irrigation and salt washing method: When leisurely, fresh water is filled in the greenhouse to form 3 to 5 cm deep water. After the soil salt is fully dissolved, water is discharged from the drain, which can effectively reduce the salt content in the soil. Third, indirectly improve the soil law 1. Scientific fertilization method: in the greenhouse with a longer plant life, available nitrogen and available phosphorus content is quite rich, should increase biological fertilizer, micro-fertilizer, carbon dioxide fertilizer and organic fertilizer, and vigorously promote the straw also field. 2. Change crop rotation: After growing vegetables for several years, cultivation of corn and wheat can effectively reduce soil salinity. 3. Biological control methods: First, antagonistic bacteria can be introduced into the soil to inhibit the spread of pathogens; second, beneficial microorganisms can be used to decompose toxic substances in the soil; and thirdly, some crops (such as onions and garlic) can release some chemicals to inhibit the development of pathogens.

According to the medicinal part, we classify traditional Chinese medicine as Chinese Medicinal Herbs Rattan Wood. Most rattans differ from other palms in having slender stems, 2–5 cm diameter, with long internodes between the leaves; also, they are not trees but are vine-like lianas, scrambling through and over other vegetation. Some rattam wood have abundant medicinal value, we develop them and apply to herbal medicine area.Such as SPATHOLOBI CAULIS or SPATHOLOBI CAULIS
