During the "Equinox" and "Winter" period, it is the period when the fruit of the green mandarin enlargement and the autumn shoot that is the mother branch of the leap year begin to mature. During this period, the management of the citrus garden has a great relationship with the increase in production and income in the current year and the following year. It can focus on the “big shots and strong fruits” as the center, and focus on the following tasks: 1. Reasonably fertilize the “equinox” to “early winter” During the period, the fruit quickly expanded and the autumn shoots became old and mature. The demand for nutrients was high. In order to solve the nutrients required for the tip fruit, the tree with more fruits is used. Each plant uses 0.1 kg of urea, 0.2 kg of compound fertilizer, and 2.5 kg of plant ash to mix; or a mixture of 50 kg of high-quality manure and 0.5 to 1 kg of cooked cake. Application, 1500-2000 kg per mu. At the same time, with urea 150 grams + 100 grams of potassium dihydrogen phosphate water 50 kilograms, or 1 kilograms of plant ash + human urine 10 kilograms of water 50 kilograms for extra-root fertilizer. For citrus trees that grow vigorously and have little fruit, phosphorus and potassium fertilizers are mainly used to prevent the occurrence of “stacked shoots” due to excessive nitrogen fertilizer. Second, irrigation drought and shoot growth and fruit development require a lot of water. During the “Equinox” to “Lidong” period, there is less rainfall, and the supply of soil moisture is in short supply. Irregular irrigation will affect the fruit enlargement and the growth of autumn shoots. Generally, the principle of night irrigation and morning irrigation and deep irrigation is the principle. Every 6 to 7 days should be used for irrigation. It is advisable to reach 50% to 60% of the depth of the trench, and the water spray can be used to improve the citrus microclimate. Citrus garden grass to musk (stunning grass), can reduce the incidence of pests and diseases. III. Timely Prevention and Control of Diseases and Pests During the “Equinoxes” to “Every Winter” periods, the weather is dry, the temperature is suitable, and pests and diseases are prone to occur. It is also the second peak of the occurrence of the spider mites in the garden. There are many types of pesticides used to control fleas and they can be used interchangeably. 1? Starscream: can be used to kill 2000 times liquid fleas or pyridazinone 3000 ~ 4000 times the liquid to kill the prince 2000 ~ 2500 times liquid, konjac Po 2000 ~ 3000 times liquid spray. 2? citrus fruit fly: (1) artificial control. Victims were mixed in a ratio of 25 kg plus 0.5 kg of sulphur granules and sealed in bags for 10 days to kill fruit larvae. Bacteria were also used to kill larvae by scalding, deep burying, and incineration. (2) sexual sedation. Three to four prepared traps per acre were hung on the mangroves about 1.5 meters away from the ground to trap male adults, and 1.5 to 2 milliliters of imported traps were added to the traps every 15 days. Flies. 3? scale insects: can be quickly culled 100 to 150 grams of water 50 kilograms, or 100 grams of grams of konjac water 50 kg spray. 4? ulcer disease: carbendazim 100 grams can be used to water 50 kilograms, or 100 grams of Rademere water 50 kilograms, or with large Gato 1500 to 2000 times spray control. In addition, the mountain nectar plants are often harmed by fruit sucking moths, and can be manually captured or bagged to protect the fruit. China Agricultural Network Editor
