苹果矮化密植栽培有以下特点:①结果早;②单产提高快;③果实成熟早,品质好;④管理方便;⑤充分利用土地和光能,⑥更新品种容易,恢复产量快等优点。所以近几年,矮化栽培——尤其是采用矮化中间砧栽培的趋势有增无减,但由于技术上的问题,导致矮化栽培失败的确井不罕见,其中一个主要问题是未能及时扶持中干优势,由于中干过早衰弱而达不到立体结果的目的。本文就“如何促进中干优势”的办法总结如下,供广
Apple dwarf close planting cultivation has the following characteristics: ① early results; ② yield increased quickly; ③ fruit ripe early, good quality; ④ management convenience; ⑤ make full use of land and light energy; ⑥ easy to update varieties, restore yield and so on. Therefore, in recent years, there has been an increasing trend of dwarfing cultivation, especially dwarfing rootstock cultivation. However, due to technical problems, it is not uncommon for dwarfing cultivation to fail. One of the major problems is the failure to timely Support the advantages of the mid-stemization and fail to achieve the purpose of three-dimensional results due to the premature weakness of the mid-stemization. This article on “How to promote the advantage of ” approach is summarized as follows
