Management measures of litchi and longan from November to December

November to December is the key period and sensitive stage for the growth and development of autumn shoots, so classified management of autumn shoots must be carried out. 1. Early maturing March Red Flower Bud differentiation begins in mid-late October, and the winter shoots that germinate after that cannot become flowers and should be completely removed. 2. Precocious lychees such as white sugar (5158,-8.00,-0.15%) and Feizixiao in western Guangdong should be sprayed with foliar fertilizer to speed up ripening, and early winter shoots will grow after November, and there is no hope of blooming next year, so they must be controlled. 3. Whether the early winter shoots of early fruit trees, young fruit trees or normal-growing old trees, such as black leaves, cinnamon, glutinous rice, Huaizhi, etc., germinated in early November (Shixia, Chuliang and Gushan longan were born before the middle of November), they can be preserved, fertilized enough to prevent insects and protect shoots, and foliar fertilizer can be sprayed many times. The organic nutritive efficient nucleotides developed by Guangdong Biotechnology United Company (hereinafter referred to as "Biotechnology Company") can be selected to accelerate the green of branches and the effect is remarkable. 4. The late winter shoots of middle and late ripening litchi after mid-November and longan after late November will not be able to form flowers or very few flowers next year, so they should be killed. Choose "shoot killing king" or "Ke shoot king" produced by biotechnology company, when the new shoots are 3-10 cm long and the leaflets are just unfoliated, each packet of chemicals is mixed with water 20 kg, wet and tender shoots are sprayed and withered 1-2 days later, the shoot killing effect is good and economical, and it has the effect of controlling shoots and promoting flowers, the next year the flower ear is short and strong, and the fruit setting rate is high. 5. For the fully mature or newly green autumn shoot-bearing mother branch, litchi, longan shoot-control flower-promoting factor or special litchi shoot-control flower-promoting factor should be sprayed once, and the young and young fruit trees should be sprayed again every 25-30 days, which has a good effect on improving the flower formation rate of litchi and longan, improving the flower quality and ensuring the yield.
