以3年生梨幼树为试材,研究了4种不同灌水处理对梨幼树枝条生长和花芽形成的影响。结果表明,在冬季一次灌水(250m~3/亩)的基础上,减少土壤供水可有效地控制新梢长度和粗度,缓和树势,增加花芽数量。减少土壤供水可使幼树总生长量轻微下降,主干生长减弱,树冠长梢比例下降,中、短梢比例增加,单位主干横截面积上的花芽数明显增加。生长季节控制灌水,可节约灌水量、扩大灌溉面积、并能促使梨幼树早期结果。
The effects of four different irrigation treatments on the shoot growth and flower bud formation of young sapling pears were studied with three-year-old pear saplings as test materials. The results showed that on the basis of primary irrigation (250m ~ 3 / mu) in winter, reducing soil water supply can effectively control the length and thickness of shoots, eased the tree vigor and increased the number of flower buds. Reduce the total water supply can reduce the total sapling growth slightly, the main growth weakened, crown long shoot ratio decreased, the proportion of short shoots increased, the unit of trunk cross-sectional area of flower buds increased significantly. Control of irrigation during the growing season, can save irrigation, expand irrigation area, and can promote the early results of young saplings of pear.
