| 摘 要： | 本文以河西走廊干旱荒漠区葡萄园为试验样地,测定了两种不同灌溉处理下的土壤含水量。在1年的生长周期中,处理1灌溉次数比处理2少18次,灌溉定额少495 m3/hm2;葡萄地上生长无明显差异,但处理1地下根系分布明显比处理2深10 cm左右,且处理1根系水平分布明显比处理2少,但垂直分布多;处理1比处理2杂草少且生长缓慢;冬季埋土前处理1葡萄枝条木质化明显好,来年出土后处理1枝条成活率好于处理2,且发芽快,枝条健壮。通过测定土壤墒情灌溉不同处理的分析,处理1比处理2节水12%,比大水漫7灌至少节水60%。 |

| Abstract: | Soil moisture of two different treatments were determined.The result showed that treatment I need 18 times less of irrigation than treatment II and 395 m3/hm2 less of water than quota given.The growth of vine have no difference between two treatments but treatment I have deeper roots,10cm deeper than treatment II.There are less weeds growing through treatment I than through treatment II.In winter,vine twigs with treatment I have better liginification before winter over than with treatment II,and also sprout... |
