苹果要获得早结果早丰产的良好效果,根据我们十多年的研究和总结各地经验,认为必须在加强土肥水管理,促进快长树、多增枝、保持强壮树势的基础上,通过采用适当的冬夏修剪措施,辅以防治病虫、提高座果率等综合技术措施,即可早结果并获得丰产。现仅幼树夏剪技术的主要内容提供参考。一、拉枝开角:开张枝条的角度,可以改变枝条生长极性,控制生长,促其向生殖生长转化,改善树冠的通风透光条件,促进多年生大枝的中后部枝条生长健壮,促进芽的萌发,增生新枝。具体作法是:对骨干枝(主侧枝)要按整形的要求,拉成
According to our more than 10 years of research and summarizing experiences from all over the world, we believe that we must, on the basis of strengthening the management of soil and fertilizer and water, promoting the growth of fast-growing trees, increasing branches and maintaining strong tree vigor, Appropriate winter and summer pruning measures, combined with the prevention and control of pests and diseases, improve fruit rate and other comprehensive technical measures, you can early results and access to high yield. Now only the main content of young tree summer shear technology to provide reference. First, the angle of opening branches: the angle of opening branches, you can change the polarity of branches growth, control of growth and promote its conversion to reproductive growth, improve the ventilation and light conditions of the canopy, and promote the growth of perennial branches in the back of strong branches, and promote buds Germination, proliferation of new branches. The specific approach is: the backbone of the main branch (sticks) according to plastic requirements, pulled into
