First, timely application of fruit fertilizer 1, fertilization period. The early-maturing varieties were applied immediately after harvest, while the middle and late-maturing varieties were applied side-by-side, or they were applied 7-10 days before harvesting. 2, the amount of fertilizer. Generally, according to the annual fertilization standards, this year due to the impact of meteorological disasters, the orange trees with less or no fruiting results, such as orange anvils, can be used less or not. The surface is micro-supplemented with foliar fertilizers with higher nitrogen content; normal fruit trees are harvested with organic fertilizers as the dominant fertilizer, supplemented with inorganic fast-acting fertilizers (ratio of organic nitrogen and inorganic nitrogen is 1:1), and organic fertilizers The types include bar fertilizer, manure fertilizer, cake fertilizer and earth miscellaneous fertilizer (these organic fertilizers must be used after being harmlessly treated), organic-inorganic compound fertilizers can also be used, and oranges with more results and weaker vigor. In addition to fertilizing on the ground, trees need to make micro-compensation on the foliage. The foliar fertilizer can use micro-filling force, micro-filling Bili, Green Fenwei 2, micro-supplementing safe nitrogen or various types of rare earth fertilizers. 3, fertilization method. This time fertilizes with eucalyptus. In recent years, ground spreading has been widely used in fertilization methods. The obvious disadvantages of this method of fertilization include two points: First, serious loss of fertilizer and low utilization rate; Second, roots grow upward, and stress resistance is reduced. Alfalfa fertilization can overcome the above drawbacks, especially organic fertilizers. Second, adjust the amount of flowers 1, the initial result tree. Tree growth is stronger. Trees with high levels of nitrogen fertilizer are not conducive to flower bud differentiation. Use 15% paclobutrazol 150-200 times solution to spray the leaves from late October to mid-November, or apply some superphosphate to the ground. Mountainous regions should apply calcium magnesium phosphate fertilizers to promote flower bud differentiation. 2, the result tree. Foliar micro-compensation, micro-replenishment force, potassium dihydrogen phosphate, green Fenwei 3, 2% of the superphosphate soaking liquid. The above-mentioned foliar fertilizers were used alternately and sprayed 2-3 times, which can obviously promote flower bud differentiation and improve flower quality. 3, weak tree. Precocious Satsuma mandarin oranges, local early, sorghum 1 1 1 -12 -12 -12 -12 -12 -12 -12 1 1 1 1 1 1 月 用 公斤 公斤 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 Saplings spend two consecutive times with the above concentration and time, the effect is more obvious. Third, winter trim (a) trim objects. 1. Cut away dead branches, branches and branches, dense branches and cluster branches. 2, cut off the leaf tip moth harm autumn, late autumn shoots, secondary results of the late summer and early fruits, such tips in the pruning, must be cut to the spring shoots or summer shoots of the first bud. 3, processing as the result of the branch and the resulting mother branch. 4. For the cross-branch, overlap-branch, and senescence shoots, remove or retract them. 5. Too many mothers should result in appropriate short cuts, with a ratio of 3-4:1. (b) Pruning time. It should be trimmed according to the growth of the orange tree and the amount of the result. For the orange trees with more results, the pruning period should be postponed as appropriate, and it can be trimmed in December; for the fruit trees with too little or no result, the pruning period should be earlier. 4. Timely Clearance After Harvesting This year due to the impact of climate disasters, the base number of diseases and insects is relatively high. This has caused certain difficulties for the prevention and control of pests and diseases in citrus fruits in the following year. Therefore, it is necessary to do a good job in the post-harvest and Mingchun spring gardening work. . The clear garden must be crowned and evenly sprayed on the ground. The agent can be used with 99% of green eugenol 250-300 times or crystalline sulfur 100-120 times. Use the above two drugs to pay attention to weather and air humidity. 5. Antifreeze tree trunks and large branches are painted white, which not only controls the pests but also improves the frost resistance of the tree. Combine with fertilization to clean up the soil and cover with organic matter or plastic film. When the orange orchard is sprayed or sprayed on the canopy before and after noon during the freezing and thawing, the low-concentration foliar fertilizer may also be combined with micro-filling.
