When entering Futian County, Shandong Province, a vegetable planting base in Gaoqing County, Shandong Province, used crop rotation and ramming, and adopted a new technique to exterminate insect pests, the high-temperature stuffy shed. Li Yubo, manager of the Nongkai Rice Planting Base, said that the insecticide is reduced by 2% with a stuffy shed method, and the effect of disinfestation is good. What's more important is that the vegetables produced using this method generally have a green quality.
High temperature stuffy shed, is the use of summer heat and drug fumigation to kill various bacteria in the shed. This technology not only eliminates germs, kills eggs, removes weeds, and improves the benefits of soil. What's more important is that this technology can greatly reduce the incidence of vegetables and reduce chemical pollution from the source of vegetable production.
Gaoqing County high temperature stuffy shed sterilization technology, generally carried out in the summer of July to August. Before the drapery, the land in the shed is leveled and finely ground, and organic fertilizer such as chicken manure and pig manure is applied together so as to kill pathogenic eggs in the organic fertilizer with high temperature. Then deep-flip, foot water, ridge cover film, and finally sealed vegetable greenhouses. High-temperature stuffy shed time is about 15 days. It is covered with high-temperature and double-layer film in summer. The temperature in the shed can reach 70~80°C. The temperature in the depth of 20 cm can reach 50°C or so. It can inactivate the soil and pathogen in the organic fertilizer with high temperature. Eggs, the sterilization rate can reach more than 80%, to a large extent reduce the incidence of vegetable diseases and insect pests, pesticide use can be reduced by 2 to 30%.
According to Li Xihong, head of the Vegetable Bureau of Gaoqing County, the method of extinguishing worms is mainly carried out during the crop rotation and renewal. “The greenhouse crops of Nongkai’s vegetable base are tomatoes, which are grown on rims. Generally, they are planted in September every year. They are planted in June of the following year, and are covered with sheds in July and August. After the shed is stuffy, they return to the season of seedlings, annual cycles. Li Xihong said that although the technological content of this technology is not high, it works well and has been promoted in more than 40 large vegetable planting bases throughout the county.
It is understood that Gaoqing County is actively creating export safety demonstration zones for agricultural products. They have formulated strict drug standards and resolutely eliminated excessive pesticide residues in vegetables. High temperature stuffy sheds reduce the amount of medication and improve the quality of vegetables.
