The key technologies of intensive seedling raising, open field and pollution-free production in facilities will be popularized and applied in vegetables.

(A) intensive vegetable seedling technology

Choose facilities with excellent structural performance, promote intensive seedling raising, and focus on popularizing and applying key technologies such as compound varieties with high disease resistance, high quality and high yield, hand-held plug seeder, plugs with appropriate number of holes, and environment-friendly substrate (peat content is not more than 50%) to cultivate healthy seedlings without pests and diseases.

(2) Pollution-free production technology of vegetables in the open field

Focus on the popularization and application of deep furrow ridge cultivation, drip irrigation, plastic film mulching, frequency vibration insecticidal lamp, sex pheromone and other agricultural physical control technologies, high-efficiency and low-toxicity biological control technologies of plant-derived pesticides such as matrine and pyrethrin, and scientific and safe use technologies of pesticides.

(3) Pollution-free production technology of protected vegetables

Focus on promoting the popularization and application of seven key technologies: first, facilities with excellent structural performance, curtain rolling machines and new covering materials; The second is the physical pest control technology based on insect net and yellow (blue) board; Third, drip irrigation under the film and anti-fog and anti-aging functional film are the main technologies to control humidity and prevent diseases; Fourth, bumblebee pollination replaces plant hormones to protect flowers and fruits; Fifth, biological control technology based on plant-derived pesticides and insect virus preparations; Sixth, safe and scientific medication technology; Seventh, soil testing and formula fertilization technology.

Second, the pollution-free production technology of fruit

Focus on popularizing and applying high-quality pollution-free fruit cultivation techniques.

(1) Apple

1. High quality cultivation techniques. First, newly planted apple orchards, selecting middle-early maturing varieties, adopting suitable virus-free dwarf rootstocks, high-quality large seedlings and wide planting; The apple orchard has achieved fruitful results, and simplified tree pruning and dwarf plastic technology are adopted. The second is to improve soil fertility and popularize the application of organic fertilizer and planting grass in orchards. The third is water-saving irrigation and installation of drip irrigation facilities. The fourth is fruit bagging, and reflective film is laid on the ground. At the same time, gradually promote the application of water and fertilizer integration, orchard lawn mower, motor sprayer and other small machinery.

2. Pollution-free cultivation techniques. First, through comprehensive measures such as fertilization, pesticide application and management, the tree vigor is restored and the occurrence of diseases is reduced. Second, adhere to prevention-oriented, comprehensive prevention and control, and promote physical prevention and control technologies such as color plates, frequency-vibrating insecticidal lamps and sex attractants, as well as biological prevention and control technologies such as high-efficiency and low-toxicity plant sources and biological pesticides. Third, rational use of pesticides and strict implementation of safe interval harvesting.

(2) Citrus

1. High quality cultivation techniques. First, the newly planted orchards are planted with virus-free container seedlings. Second, planting grass in the orchard can improve the orchard environment, enhance soil organic matter and prevent soil erosion. Third, scientific fertilization to improve the nutritional status of trees. Fourth, the pruning technology of big branches is adopted to improve the ventilation and light transmission conditions of trees. Fifth, picking after ripening to ensure fruit quality. At the same time, promote the integration of water and fertilizer technology with small machinery such as orchard lawn mower and motor sprayer.

2. Pollution-free cultivation techniques. First, increase the row spacing, raise the trunk, widen the angle of main branches, keep the orchards and trees ventilated and transparent, and create an environment that is not conducive to the spread of pests and diseases. The second is to release predatory mites, hang yellow boards, and set up frequency vibration insecticidal lamps. The third is to plant crops such as agastaches and thistles between rows to improve the ecology of orchards and protect natural enemies. The fourth is to strengthen forecasting and reduce spraying times. Fifthly, biological pesticides with high efficiency and low toxicity are selected for prevention and control. Sixth, strengthen the monitoring and prevention of quarantine pests and diseases.

Three, pollution-free production technology of tea

Tea focuses on the popularization and application of high-quality seedlings without pests and diseases, pollution-free production and clean processing technology.

(1) high-quality seedlings, no pests and diseases.

Select the breeding farm of tea seedling clonal seed, and integrate the techniques of clonal seed, facility protection (greenhouse, sunshade net), short cuttings, pest-free substrate and so on.

(2) Pollution-free production technology

1. Pest prediction and unified control. In the large-scale tea production base, the establishment of pest forecasting points, equipped with plant protection personnel and forecasting lights, to carry out tea pest forecasting work, irregular release of pest information, organize unified prevention and control.

2. Physical prevention and control technology. Choose centralized contiguous tea production base, and focus on popularizing and applying frequency vibration insecticidal lamp and yellow (green) board trapping and killing technology.

3. Biological control technology. Focus on the popularization and application of plant-derived pesticides such as matrine and pyrethrin, and the control technology of tea caterpillar and tea geometrid virus preparations.

(3) Clean processing and production technology

Choose large-scale tea processing enterprises, focusing on the promotion and application of continuous, automatic and clean processing.
