Method for overcoming soil continuous cropping obstacles in vegetable greenhouse

Abstract

The invention provides a method for overcoming soil continuous cropping obstacles in a vegetable greenhouse. The method is used for crop rotation of vegetables and pastures or intercropping of the vegetables and the pastures, a base fertilizer formula is applied in the pasture planting process, and the base fertilizer formula comprises a biological organic fertilizer, a balance compound fertilizerand an anti-continuous cropping microbial agent. According to the method, crop rotation of monocotyledons (pastures) and dicotyledons (vegetables) is utilized, and the anti-continuous cropping microbial agent is used for antagonizing harmful disease microorganisms in soil in the pasture planting process; harmful substances in the soil are degraded; growth and development of crop roots are stimulated; and beneficial microbial communities are rapidly established, the soil microbial ecological environment is improved, and soil continuous cropping obstacles are overcome. Due to different fertilizer requirement rules, crop rotation of the pastures and vegetables can enable various nutrient elements to be fully absorbed and utilized, and main elements in the soil are kept in relative balance.

Description

Technical field[0001]The invention belongs to the technical field of soil improvement, and in particular relates to a method for overcoming soil continuous cropping obstacles in vegetable greenhouses.Background technique[0002]Greenhouse vegetable planting industry is facing many challenges, the more prominent problem is the obstacle to continuous cropping of soil. With the increase of the continuous cropping years of facility vegetables, soil, fertilizer and water management techniques are unscientific, and the perennial application of chemical fertilizers is the leading factor, resulting in increased obstacles to the continuous cropping of facility vegetables.[0003]The specific manifestations are as follows: 1. The secondary salinization of soil is aggravated. The long-term accumulation of salt in irrigation water and water-soluble fertilizer leads to an increase in the pH of the cultivated soil, and the soil EC value exceeds the critical value of vegetable fertility failure. 2. So...

3. Nutritional imbalance

Long-term monoculture leads to unbalanced nutrient absorption, and the soil pH is too acidic or too alkaline to reduce the availability and availability of soil nutrients, resulting in the imbalance of nutrients, especially macronutrients

4. Physiological diseases become more serious, and the yield and quality of vegetables decrease

5. The ecological imbalance of soil microorganisms, soil-borne diseases and insect pests or difficult diseases and insect pests continue to appear, which increases the difficulty of the safety prevention and control of vegetable diseases and insect pests, resulting in frequent occurrence of diseases and insect pests, excessive use of drugs, and poor control effect, seriously affecting the yield, quality and safety of vegetables
