Soil, Fertilizer and Water Management Appropriate control of the amount of fertilizer in autumn, especially nitrogen fertilizer, that is, less nitrogen fertilizer, suitable phosphate fertilizer, increased potassium fertilizer, and multiple sprays of calcium fertilizer to help improve fruit quality and reduce fruit cracking and puffiness. Fertilization for young trees should be stopped; for orange orchards with a lot of fruit and normal soil fertility, fertilizers for strong fruit and shoots based on phosphorus and potassium fertilizers can be appropriately supplemented to promote the growth of autumn shoots and compensate for the large amounts of nutrients consumed during fruit expansion. Orange gardens can choose to use potassium chloride. As the citrus fruits continue to expand and require a large amount of water, water should be irrigated in time during drought. At the same time, tree tray bio-covering or film covering can be used to reduce the impact of drought on fruit quality.
Fruit management September is the period of high occurrence of fruit cracking in navel orange, Yuhuan pomelo and other varieties. We will continue to adopt comprehensive measures to prevent and control fruit cracking and reduce the incidence of fruit cracking. Extra early ripening Wenzhou tangerines are selected and harvested according to the quality and coloring of the fruit. Continue the administration in August, spray 2% calcium carbonate once every 20 to 30 days or spray 2 times every other week with 1% concentration to reduce the occurrence of puffiness. Continue to pay attention to the thinning of the fruit of too many orange trees, the thinning of dense small fruits, deformed fruits, and pests and diseases.
Disease and insect pest control September is the second peak period of red spiders. Close attention should be paid to the insect situation and timely control. You can choose 95% motor oil emulsion (or anti-dead insect EC, green glume EC) 150-200 times liquid, 20% double Formamidine EC 1000 to 1500 times liquid; start to spray 0.3 to 0.4 degree lime sulfur mixture 1 to 2 times in late September to prevent insects and fruit coloring. Citrus anthracnose is prone to occur after heavy storms and rains during the fruit growth period and at the early stage of fruit maturity, which will reduce the storage performance of the citrus fruit. In severe cases, it will cause fruit drop before picking. You can spray 0.5% equivalent Bordeaux mixture or 75% chlorothalonil. Powder 800 times liquid or 70% thiophanate methyl wettable powder 800 times liquid or 50% carbendazim wettable powder 600 times liquid, etc.
