First, orange garden fertilizer It is necessary to apply timely, reasonable and appropriate fertilization according to the tree planting trend, yield level and soil fertility. 1. The tree vigor is weak and there are many deciduous orange orchards: Apply 3 kg of organic fertilizer for citrus or 25 kg of decomposed organic fertilizer, apply proper amount of compound fertilizer; The second time, 15 days before germination, apply effective fertilizer, mainly Eat less meals, apply thin fertilizers, generally apply 0.3-0.5 kg. The shoots of spring shoots begin to turn green, or they are sprayed with 0.3% potassium dihydrogen phosphate and 0.2% urea before and after flowering, and they are sprayed at intervals of about 7 days and sprayed 2 or 3 times to accelerate the tree rejuvenation. At the same time, we should promptly do a good job of cultivating loose soil, eradicate the weeds in the trees and accelerate the increase of soil temperature. In the spring and the rainy season, drainage and loose soil work should be conducted in a timely manner to increase the permeability of the soil and increase the activity of the root system. 2. Normal orchard fertilization: Spring fertilizer application time is applied before germination, and fertilizer is applied with citrus organic fertilizer combined with compound fertilizer. The annual output of 50 kilograms of orange tree applies citrus organic fertilizer 3~4 kilograms. Fertilizer 0.5 kg to open the ring groove 15cm, after the fertilizer is applied and covered with soil and mix well. 3, young orange orchard: should be to expand the canopy for the main purpose. The first is to step up the expansion of soil and fertilizer management to cultivate a better canopy. Combining application of organic fertilizers to expand soils to increase the growth of young trees' roots, and in addition to applying fertilization prior to the germination of oranges, freshwater fertilizer must be applied every 15 days, mainly human excrement or animal excrement; Fertilizer, for 2-3 years, the amount of trees used for the application of urea 22, or compound fertilizer two two, the fertilizer watered in the shallow ring groove from the trunk 30-50cm Department. After planting the tree, it is required to cover the black mulch within 1m of the tree to accelerate the growth of the tree. Second, orange tree pruning 1. Pruning of the result tree: The pruning of citrus trees in early spring is a key task for the management of the orange orchard. The orange groves in various places must complete this task according to the actual situation before the sprouting of the orange trees; in particular, the pruning of large branches of orange trees is a long-term management of the orange orchards that is tight, demanding, and technically strong, and also ensures the growth of the tree vigor. An important measure to improve the quality of fruit; pruning of large branches of adult fruit trees, reducing the height of crowns, stabilizing tree vigor and height, and ensuring tree vigor and branches are in an orderly manner. In general, the number of large branches in each plant should not exceed two. In addition to the strongest, highest dominant branch or densely intersecting branch, a “skylight†is created to form a tree that is both airy and light, with a tree crown, and then retracted from the previous year’s results, and cut off the dead branches inside the crown. , pests and branches, mold branches. After the big branch is trimmed, pay attention to the wound and keep the self-made “Sanling Ointment†(1g 900g, 5g thiophanate, 5-10g petrolatum or butter) on the cutting edge; the amount of pruning in the year is generally controlled by the amount of leaves per branch. 1/4 to 1/3. 2. Pruning of young orange trees: It is mainly to cultivate the tree canopy and expand the tree body. When the new shoot grows to 5-7 leaves (5 inches) per season, it will be picked up and the dense shoots will be removed. Third, the main pest control in spring The vast majority of orange farmers in the city must earnestly do a good job in the field investigation of pests and diseases, and strictly follow the requirements of the "non-environmental pollution citrus production regulations" to carry out pest control in the orchards. 1. Early Spring Garden: The early spring garden of Orange Garden is an important work to reduce the incidence of diseases and insect pests in the year. It has obvious effects on reducing the number of overwintering pests and diseases, reducing the number of pests in the year, and reducing the number of pests. All orange orchards are required to be combined with pruning in early spring, severe pests and branches (such as scabs, overwintering branches, etc.) are severed and burned in a concentrated manner. Then the orchard is cleaned thoroughly; the use of pesticides is 50% exterminated or 50%. Melt kill 80-100 times liquid. For heavily deciduous orange orchards, it is recommended to use 40% crystal lime sulfur 100 times solution, or 0.8 Baume degree lime sulfur, or 0.8:0.8:100 (copper sulfate: quicklime: water) lime equivalent spray Bordeaux , Or 77% tannin wettable powder mixed with 5% Nissorange EC 1000 times, both prevent disease but also play a role in killing. All branches, leaves, stems, and roots of the orange must be sprayed when spraying. 2. Main pest control methods 1 resin disease (black spot disease): If the orange tree wounds, dry branches, more likely to cause resin disease. Increase organic fertilizers and compound fertilizers, increase phosphorus and potassium fertilizers, and increase tree vigor. In the spring, summer and autumn shoots, young plants will be sprayed once every 15-20 days during the young fruit period and from August to September. The following agents are available: 80% WPWP 700 times, 70% chlorfluazuron WP 600-800 times, 70% mancozeb WP wet 600 times, 50% WP WP 700 times Liquid, 75% chlorothalonil wettable powder 600-800 times liquid. 2 Scars: 0.8% equivalent Bordeaux mixture can be used to prevent and protect the oranges before they germinate; 20% of the Roche bacteria can be used when the buds are 0.3 centimeters long, flower buds, and flower buds 2/3, and the middle and late June. Times of liquid, 50% Xinling WP 700 times, 75% chlorothalonil wettable powder 600-800 times to control. 3 red, yellow spider: available 5% Nisuolang 1500 times; 5% Bazhi Ling 1000 times, 15% fluorenone (Li Dasheng, Xi Ling, broom net, etc.) 1200-1500 times; 50% carbendazim (acetylene, chlorpheniramine) 2000 times, 20% triazotin 1500 times, etc. were used for prevention and treatment. 4 Flower buds: In the dew-white period of the orange tree, the ground is sprayed with 50% phoxim 1000 times solution, 48% Lobster 1000 times solution, or 52.5% farmland 1500 times solution. 5 scale insects and whiteflies: 40% culling 1500 times, 48% 1200 times or 40% chlorpyrifos 1000 times, or 50% lingolids 1200 times in the period of insect pests. Or 10% imidacloprid 3000 times, adding 99.1% Lv Ying 300 times or 95% Zhai Ling 300 times for control. 6 Subalbumin A: It was sprayed on the canopy of the rapid growth period of spring shoots from the shoots of the new shoots to 48% Locust 1000 times, 50% phoxim 1500 times, and 1.8% abamectin 3000 times.
