野生板栗嫁接早期经营管理技术,采用整形修枝、虫害防治、土壤施肥三因子三水平的正交试验,结果表明:整形修枝和虫害防治二因子对板栗生长和结实有一定影响,但不明显;土壤施肥不但树体长势好,而且结实量明显增加,是板栗早期丰产、稳产的主导因子。通过三项技术管理,板栗株产年平均可增加0.57kg,年平均增产幅度为30.4%,具有较大的增产潜力。
Early chestnut grafting management techniques, the use of plastic pruning, pest control, soil fertilization three factors three levels of orthogonal test results showed that: plastic pruning and pest control two factors on the growth and fruiting of chestnut have some effect, but not obvious Soil fertilization not only made the tree grow well but also significantly increased the seed yield, which was the main factor for the early yield and stable yield of chestnut. Through the three technical management, chestnut plant annual output can increase 0.57kg, the average annual rate of increase of 30.4%, with greater yield potential.
