一、问题的提出苹果的矮化密植栽培具有树体小,结果早,树冠紧凑产量高,果实均匀品质好,便于机械操作等优点.因而成了国内外果树发展的必然趋势.但它也有许多缺点,诸如:根系不发达.抗逆性差,苗木繁殖较困难等,这就严重的限制了它的发展速度.为了解决这些问题.我们试图以乔砧进行密植栽培,认真观察研究,以期在生产上有所应用.我们县1977年后,相继发展了两万多亩乔化砧苹果,栽植密度大都为3×6米,每亩37株.这就提出了乔砧密植栽培如何管理问
First, the problem put forward Apple dwarf dense planting has the advantages of small tree body, early results, compact crown yield, uniform fruit quality, ease of mechanical operation, etc. It has become the inevitable trend of fruit trees at home and abroad, but it also has many Shortcomings, such as: underdeveloped root system, poor resistance, seedling breeding more difficult, which severely limits its speed of development.In order to solve these problems, we try to close planting with Joe anvil, careful observation of research, with a view to production On the application of our county after 1977, have developed more than 20,000 acres of Qiaohua an apple, planting density mostly 3 × 6 meters, 37 acres per mu. This proposed Qiao ani close planting culture management
