阿图什市上阿图什乡种植核桃已有悠久的历史。过去由于大多是异花授粉和实生苗繁殖,因此在结果性状和果实品质等方面的差异十分显著,优果更少。为改变这种落后状况上阿图什乡林管站与阿图什市林管站联合采取措施,选用优良树种育苗并利用嫁接技术,使核桃生产提高到一个新的水平。采取嫁接技术进行换冠改造不仅成活率高,而且树冠恢复快,产量和品质都有显著提高,如一般树30年生单株产量1.80千克,而优种树10年生单株产量3.35千克。关键在以下几个方面:一、嫁接时间
There is a long history of growing walnuts on the town of Altush, Atushi. In the past due to mostly cross-pollination and seedling multiplication, the differences in the traits and fruit quality were significant, with fewer benefits. In order to change this backward situation, Artush Township Forest Management Station and Artush City Forest Management Station jointly take measures to select good seedlings and grafting techniques to make walnut production to a new level. Grafting technology for crown transformation not only has a high survival rate, but the crown resumes fast, yield and quality are significantly improved, such as the general tree 30-year-old plant yield 1.80 kg, while the superior tree 10-year-old plant yield 3.35 kg. The key lies in the following aspects: First, grafting time
