The old experts compiled the citrus green comprehensive prevention and control technology simple and practical
Official network news (reporter Liu Hongjin) Yichang City Elderly Science and Technology Association citrus expert group recently compiled a set of "citrus green food production comprehensive prevention and control technology", simple and practical, save labor, reduce costs, in the case of quality improvement and yield harvest, to achieve green food citrus production, deeply welcomed by the majority of citrus growers in citrus producing areas.
Citrus green comprehensive prevention and control technology, that is, based on agricultural control, combined with balanced fertilization, and the comprehensive use of physical control and biological control measures, to achieve citrus production management thorough comprehensive green prevention and control, the number of citrus disease and pest control drugs throughout the year to 2-3 times, the safety interval of each drug to 2-3 months, the base of diseases and insects is controlled at a very low level.
According to the promotion and application of citrus producing areas in Zhijiang City, Danyang City, Xingshan County, Yuan'an County, Changyang County, Yiling District and other places, not only is the prevention and control of diseases and insects effective, but also the increase in production and efficiency is obvious. According to statistics, the average labor saving per mu of citrus management is 3-4, and the cost of medication is reduced by 50 yuan; the fertilizer utilization rate can be improved by 40% after balanced fertilization, which greatly reduces the pollution of soil and water quality by chemical fertilizers. At the same time, the quality of citrus has been greatly improved, the commodity fruit rate has reached more than 90%, and the area where citrus green comprehensive prevention and control technology is applied, the benefit per mu has increased by 500-1000 yuan.
Technical gist and objectives: Citrus green comprehensive prevention and control technology, that is, based on agricultural control, combined with balanced fertilization, and the comprehensive use of physical control and biological control measures, to achieve citrus production management thorough comprehensive green prevention and control, the number of annual medication reduced to 2-3 times, the safety interval of 2-3 months, the base of diseases and insects controlled at a very low level.
The use of yield increase and efficiency: the average labor saving per mu of citrus management is 3-4, the cost of medication is reduced by 50 yuan, and the fertilizer utilization rate can be improved by 40% after balanced fertilization, which greatly reduces the pollution of soil and water quality by chemical fertilizers. At the same time, the quality of citrus has been greatly improved, the commodity fruit rate has reached more than 90%, and the application of citrus green comprehensive prevention and control technology has increased the benefit by 500-1000 yuan per mu.
Key points of green prevention and control technology:
1. Raw grass cultivation. There are two types of raw grass cultivation in orchards: one is the cultivation of special grasses, such as rye grass, baixi grass, duck thatch, purple cloud, etc.; the other is the use of natural weeds (uprooting high-stalk, deep-rooted weeds, leaving shallow-rooted short-stalk weeds to let them grow naturally). When the weeds are too high, use mechanical pruning or use a herbicide that does not hurt the roots- anhydroxal phosphine
。
2. Balanced fertilization. Soil fertilization focuses on the application of two times, one for strong fruit fertilizer, the time is mid and late June, the amount of consumption accounts for 30-40% of the annual amount, the fertilizer is decomposed organic fertilizer + citrus formula fertilizer (high nitrogen and high potassium type) + fruit and vegetable calcium (plant application 0.5-1 kg); or the application of low concentration organic - inorganic citrus special formula fertilizer + fruit and vegetable calcium.
The other time is the base fertilizer, which is from mid-October to mid-November, and the amount of fertilizer used accounts for 60-70% of the annual fertilizer application. The fertilizer is decomposed organic fertilizer + citrus formula fertilizer (nitrogen, equilibrium type) + 15% fine boron + 25% full grain zinc, or organic - inorganic citrus special formula fertilizer + 15% fine grain boron + 25% full grain zinc. The organic fertilizer applied should be harmless compost, manure, manure, biogas fertilizer, green manure, cake manure or bio-organic fertilizer.
3. Pest control. Based on agricultural control, the comprehensive use of physical control and biological control measures to achieve thorough comprehensive green prevention and control, the number of drugs used throughout the year has been reduced to 2-3 times, the safety interval has reached 2-3 months, and the base of diseases and insects has been controlled at an extra low level.
(1) Spring prevention: prevention and control time budding period. The targets of control are red and yellow spiders, whiteflies, mesozoans, aphids, leaf beetles, flower bud maggots, resin diseases, scabs, macular diseases, etc.
