果树定植时如果技术措施不全面,容易出现大量死株现象,个别年份成活率不到30％,是旱作农业区果园建设的一大障碍。我们通过在多种果树上进行栽植试验,摸索出了解决这一问题的有效办法,可使苹果、梨、桃、杏、柿子、葡萄等果树成活率提高到98％以上,使枣树当年萌发率提高87％以上。其关键技术措施是: 1、巧用天时,适期栽植。旱作区的特点是雨量少且分布不均,充分利用雨季可起到事半功倍的效果。如果秋季多雨,土壤持水量在60％以上则宜秋季栽植,但要埋土越冬;如果冬春雨雪较广则宜春季栽植。
Fruit tree planting if the technical measures are not comprehensive, prone to a large number of dead strains, the survival rate of individual years, less than 30%, is a major obstacle in the construction of dry farming orchards. By planting experiments on a variety of fruit trees, we found out an effective way to solve this problem, which can increase the survival rate of fruit trees such as apple, pear, peach, apricot, persimmon and grape above 98% Rate increased by 87% or more. The key technical measures are: 1, clever use of the day, the appropriate planting. Rainfed area is characterized by less rainfall and uneven distribution, take full advantage of the rainy season can play a multiplier effect. If the rainy autumn, soil water content above 60% should be planted in autumn, but to be buried overwintering; spring and winter if the winter and spring should be planted in spring.
