This project conducts in-depth research and integration of organic fertilizer production, soil improvement, green prevention and control, overcoming continuous cropping obstacles, cultivation techniques, etc., and combines it with conventional production technologies to propose a reasonable and scientific technical system, and conducts integration and demonstration, and then proposes Technical specifications for ensuring high-quality and efficient facilities organic vegetables.
This project mainly carried out research on the following innovative contents

1. Studying the production of organic fertilizers can effectively solve the problem of waste reuse in vegetable production. In this study, vegetable waste and rice straw were subjected to anaerobic composting experiments with cow manure and pig manure respectively, and the effects of four microbial inoculants on the pH value, conductivity, bulk density and specific gravity of each compost were tested. The results showed that when using vegetable waste for composting, the best raw material ratio was the ratio of vegetable waste: straw: pig manure of 10:40:50~Between 20:30:50, when composting, the starter provided by Haiqunlin Biological Co., Ltd. has the best effect.
2. Improve the soil through various measures to improve the physical and chemical properties of the soil and overcome the obstacles of continuous cropping of vegetables. The main study was to study the effect of green manure and organic fertilizer on soil physical and chemical properties, the effect of functional microorganisms on soil improvement, and the adjustment test of alkaline soil Ph value. The research showed that the soil treated with green manure is more suitable for growing leafy vegetables. If you plant melons, fruits, roots and vegetables, organic fertilizer is also added, which has the best effect on inhibiting continuous cropping obstacles in cucumber. Combined with the comprehensive consideration of PH value, yield and organic production, the organic materials include asparagus straw, adsorbent materials, chelating agents, Root protection treasure among microbial fertilizers is a good choice.
3. Solve the problem of pest and disease control in organic production through research on green prevention and control measures. The main research was carried out including the anti-insect effect test of yellow board, the anti-insect test of sex attractant, and the anti-insect test of biological agents. Through research, we found the best method to use yellow board to control cucumber Bemisia tabaci, the correct method to use sex attractants, and solved the difficulty of controlling diamondback moth in organic green leafy vegetables in bare fields in summer.
4. Through research on changing cultivation measures, find the best tomato over-summer cultivation method that suits local production conditions. The main purpose was to study the changes of different varieties and three different cultivation measures, namely pruning methods, sunshade covering and ground covering, on the microclimate environment of plants in pipe sheds in Shanghai, and to explore the effects of climate change on the physiology, yield and fruit quality of tomato plants cultivated in pipe sheds over summer. And obtain the best tomato over-summer cultivation techniques and systems suitable for local production conditions.
   Through the research on the above technologies, combined with conventional production technologies, technical specifications for planting organic cucumbers, tomatoes, and green leafy vegetables in facilities have been formed.
   The project was applied in the demonstration area to realize the industrialization of guarantee technology on 924 acres of facility vegetables. Production was carried out in accordance with organic standards and no chemical fertilizers and chemical pesticides was used. The yield per mu of vegetable types in facilities in the base was increased by more than 20%, and the output value increased by about 30,000 yuan. It solved the employment of 400 non-senior professionals, and the radiation area reached 3000 acres to implement the industrialization of guarantee technology. According to the reduction of chemical fertilizers and chemical pesticides by more than 50%, the output of organic vegetables in facilities in the base will be increased by more than 20% under continuous cropping. At the same time, through project implementation, the local agricultural ecological environment has been improved and optimized, and environmental gains and losses can be reduced by 20% every year. Therefore, the economic benefits of that year and the cumulative benefits contained over the years are huge.
