With the development of navel orange industry in Gannan. The management technology of navel orange is becoming more and more important all the year round.

1 Autumn shoot protection

Autumn shoot is the main fruit mother branch of navel orange, which should be promoted according to different climatic conditions. Generally, one week after Lesser Heat, nitrogen fertilizer was applied to promote sprouting according to the amount of fruit hanging on the plant, and after Greater Heat was put on the shoot, 25% Xiuxiuanshuang 600x liquid was sprayed on the bud eye when half a grain of rice was long to control leaf miner, once a week until the growth of autumn shoots stopped. At the same time, spray strong and slightly fat.

2 protect leaves in winter

To ensure that there are many navel orange leaves and thick green leaves is an important guarantee of high yield. From near fruit picking to flowering in the next year, emphasis should be placed on protecting leaves, that is, applying pre-fruit fertilizer half a month before fruit picking, applying pre-fruit fertilizer within half a month after picking fruit, applying post-fertilizer within half a month after picking fruit, and secondary fertilization is dominated by phosphorus and potassium fertilizer. In winter, base fertilizer should be applied in combination with clear garden, with 20 kg of pig and cattle pen fertilizer, 800 g of cake fertilizer and 500 g of calcium superphosphate per plant, and compost fire soil fertilizer project to improve the ability of trees to resist cold and protect leaves.

3 spring flower protection

The application of flower protection fertilizer is the first decision to promote full buds and good grade; when the plant thanks 50%, 0.3% urea and 2% potassium dihydrogen phosphate can be sprayed to protect flowers. If there are many buds and not many spring shoots, you can properly truncate the longer branches and cut some of the shoots. Xiehua was sprayed with 0.2% to 0.25% potassium dioxide phosphate for 2 to 3 times in a row. Pay attention to wiping buds and controlling tips to prevent fruit drop in the later stage. While strengthening fertilizer and water management, it is also necessary to bag the fruit to protect the fruit.
