Late autumn refers to the period from early to early November. During this period, it is not that Dong Kui Yang Mei has nothing to do. Instead, it controls the sprouting of autumn shoots, promotes the development of flower buds on spring shoots and summer shoots, and lays a foundation for next year's high yield. Therefore, the administration of Dongkui Yangmei during late autumn is still very important. First, control the importance of autumn shoots Because of the late autumn sprouting bud, it is not easy to form flower buds; Even if there is flower bud differentiation, but also because of the late season, flower bud development is poor, it will be difficult to result next year. However, the germination of autumn shoots and the differentiation and development of flower buds on autumn shoots consume more nutrients. This will capture the spring shoots and summer shoot nutrients, affect the spring shoots and summer shoots of flower bud differentiation and development. This is why we control the germination of autumn shoots. Second, late autumn shoots will germinate some fruit farmers asked: "after October, Dongkui Yangmei will sprout it?" Because Dongkui Yangmei in winter, as long as the temperature of 10 degrees or more for a certain period of time, it will sprout winter shoots. So in the early 10th-11th, the temperature above 10 degrees is very common. Late autumn shoots are very likely to germinate. This requires that we must pay attention to the germination and control of late autumn shoots. Third, the late autumn management of what work (a) control the autumn shoots 1, if the tree shoots less germination, can be in the shoot length of 2 to 3 cm, it is hand-picked, to shoot tip to leave the pile, so as not to pick a Meng two The phenomenon of picking two sprouts four appears. 2. If the tree is not hand-picked, it can spray 15% paclobutrazol 250 times as much as the tip of water when the young shoot is 1 cm long. But pay attention: do not mix with the pesticide or nutrient solution; avoid jetting at noon; as long as the shoot is facing the tender shoots. 3. In recent years, there are fruit growers in Huangyan, Linhai, and Jiaojiang, who think that paclobutrazol sprays more, so that the fruit shape becomes smaller. Therefore, they use lime sulfur to kill the shoots with good results. It is sunny and dry, with 80 to 100 times; and wet after the rain, use 40 to 50 times. Please all fruit farmers first test, after the application. However, crystalline sulfur cannot be used arbitrarily. (b) strong flower buds 1, pay attention to boron: as long as the tree potential does not decline and yellow leaves appear, we must pay attention to boron. To spray 1 two borax, half a dozen urea 100 pounds of boron liquid. 25 grams of boron fertilizer flushed 15 kilograms. 2, spray Tsui Kang Hua Guo Ling 700 times, or 0.2% potassium sulfate solution, or Green Fenwei 1 1000 times. To supplement nutrition and promote flower bud development.
