The amount of poplar peach blossoms is too large, the number of fruits is too much, and the tree body is overburdened. Correct use of flower thinning and fruit thinning techniques to control the number of fruits, so that the tree body is reasonably burdened, is to prevent poplar tree large and small year results and improve the quality of the important measures. It has been widely used in production.
(1) can maintain the successive years, each batch of fruit high-yield and stable yield poplar peach tree bud differentiation and fruit enlargement is often carried out at the same time, nutritional conditions are sufficient or appropriate load of flowers and fruits, both to ensure that fruit hypertrophy, but also to promote the differentiation of flower buds. But nutritional deficiencies or too many flowers and fruits, the nutrient supply and consumption of contradictions, too many fruits inhibit the differentiation of buds, easy to appear in large and small results or each batch of fruit more or less uneven phenomenon. At the same time, fruit thinning also reduces the tree overburden, enhance the tree nutrition, tree strength and resistance, to maintain long-term high and stable yield.
(2) Improve fruit quality and grade As the number of fruits is reduced, it can promote the fruit left behind to fertilize, and enhance its neatness. At the same time in the fruit thinning also thinned out the pest fruit, deformed fruit, improve the rate of good fruit. It can also improve the sugar-acid ratio and vitamin C content.
(3) significant economic benefits Due to the increase in the amount of large fruits of one or two, the sale price is 2 to 3 times higher than the three or four fruits. According to research, not thinning trees, although the plant yield is higher than thinning trees, but due to the small fruit quality is poor, the final economic income or thinning trees high.
Thinning method
At present, the general still use artificial thinning. In the poplar peach fruit grows to thumb big, with artificial thinning insect fruit, small fruit, deformed fruit, retain the fruit shape is correct, big, bearing in the thicker branches of the fruit. 1 inflorescence on only 1 ~ 2 fruit.
