实践和科学证明,灌溉是在果园管理措施制度中很重要的农业技术。在我国的南部和东南部,果树的产量直接和灌溉有关。所有的果树的主要种类——苹果、梨、榅桲、李子、酸樱桃、甜樱桃、杏都属于对水分要求高的植物。根据文献上现有的材料,如果蒸腾强度是每小时、每一平方米叶面积耗水25克,则10年生的苹果树,一小时即蒸发2.5公升多水。根据我们的研究确定,由於土壤中温度状况的不同,蒸腾强度有极大改变。在水分供应充分时,植物消耗到蒸腾上夫的水分达到一平方米叶面积每小时4O克;而在水分不足时则只有10—11克。
Practice and science have shown that irrigation is an important agricultural technique in the system of orchard management practices. In southern and southeastern China, the production of fruit trees is directly related to irrigation. The main types of all fruit trees - apples, pears, emus, plums, sour cherries, sweet cherries and apricots all belong to plants that require high water content. According to the literature available in the literature, a 10-year-old apple tree evaporates 2.5 liters of water an hour, if the transpiration intensity is 25 grams of water per square meter of leaf area per hour. According to our study, the transpiration intensity has been greatly changed due to the different temperature conditions in the soil. When the water supply is sufficient, the plants consume up to 40 grams of water per square meter of leaf surface area for the transpiration, and only 10-11 grams for the water deficit.
