September-October is the period of accumulation of early maturing cultivars, mature coloring of medium maturing cultivars, and the accumulation of nutrients in flower buds of orange fruit trees. It requires sufficient nutrients and water, and it is also the flood season of crickets. Therefore, the management points of the September-October orange orchard should focus on the following aspects: 1. Drought and Drought Reduction and Reduction of Soil Moisture Evaporation September-October is the dry season in East China, when the temperature is still high, but it is also full In the two months with the least annual rainfall, the focus of fertilizer and water management is timely drought and drought prevention, and drought prevention should be implemented as “first prevention without droughtâ€. Navel oranges are the peak period of pre-harvest fruit drop and fruit cracking. Before the drought, we should do a good job of covering the trees, keep the soil loose and moist, reduce the evaporation of soil moisture, and timely irrigation when it lasts for half a month to meet the mid-late ripening. Varieties of fruit continue to increase the demand for moisture. Second, deep rolling green, heavy fertilizer from September to October is summer green manure (mung beans, soybeans, Tian Qing, peanut vines, etc.) deep-turning greening the best season, can be combined with the application of heavy fertilizer under the ditch, to facilitate Update the root system. Specific practice: young orange citrus garden can be outside the canopy drip line to open long width and depth = 403080 cm ring into the 20-30 kg of green manure, N, P, K compound fertilizer 2.5 kg, then add to the pig cattle fat bar or Bran manure and other organic fertilizers, while adding 0.5 kg of lime, mix well with the soil and return to the pit to fill the heavy fertilizer pit, 5 cm above the pit surface. Third, to improve the soil, young fruit trees sowing winter green manure in East China Red and Yellow Soil Orange Garden, soil organic matter content is low. The cultivation of green manure is an effective measure to improve the soil, increase the source of organic matter, and cultivate gardens in order to solve the shortage of manure sources in citrus groves. Young citrus fruit trees can be planted between September and October in winter green manure. There are many types of green manure in winter: peas, ju dishes, broad beans, radishes, milk vetch, medlar and so on. Four, early maturing varieties timely fertilization after harvest early maturing early spring varieties such as mandarin orange, in the end of September in early October after harvesting fruit in a timely manner within half a time after the application of fruit fertilizer, applied per acre of pure nitrogen 5-6 kg, phosphorus 2-2.5 Kilograms, potassium 3-3.5 kilograms, to restore the tree vigor; mid-maturing varieties in late October, plant 25 tons of manure excrement, or 0.5-1 kilograms of compound fertilizers in time to supplement the tree nutrients; timely coloring of fruit after root dressing , spray 0.2% -0.3% potassium dihydrogen phosphate or green Fenwei No. 1 800 times, in order to facilitate fruit coloring, improve the appearance of finish to improve quality, and is conducive to flower bud differentiation. V. Preventing pests and diseases in a timely manner In September-October, the weather in East China was dry and the temperature remained high. It was the most endangered stage of citrus aphid (Red spider, rust spider). Therefore, it is not possible to relax the prevention and treatment of cockroaches. At this time, it is necessary to check and find out that when each field of vision has 2-3 heads, it should be sprayed in time. Commonly used agents are: dicofol, Kete EC, triazole, etc., can be sprayed once every 7-10 days, continuous 2-3 times. Other pests and diseases such as anthrax and anthrax should also be promptly controlled.
