【摘要】 在赤霞珠生产园行间播种多年生黑麦草、紫花苜蓿、白三叶草,在自然降雨条件下,研究葡萄园行间生草对葡萄植株生长发育的影响。结果表明:与清耕相比,行间生草可有效控制植株的生长势,显著降低萌芽率、坐果率和产量,降低根系密度,并促进植株根系向深层土壤发展,有利于对水分和养分的吸收。同时行间生草使葡萄叶柄N、P、K三要素及矿质元素Ca、Mg、Fe、Cu、Zn、Mn含量有升高的趋势。更多还原

【Abstract】 On the condition of natural raining, The effects on vine growth in Cabernet Sauvignon vineyard by covering with White Clover (Trifolium repens), Perennial Ryegrass (Lolium perenne) and Alfalfa (Medicago sativa) were studied. With comparison of clean tillage, the results showed that growth of the vines was controlled efficiently, rate of bud germinating percentage, fruit set percentage of vines and production of grape berry were reduced significantly, root densities were decreased,while the roots of green covering vines were stimulated to penetrate deep into the subsoil,comparing with those of clean tillage. The contents of nutrimental element, such as N,P,K,Ca,Mg,Fe,Cu,Zn,Mn,have tendencies of improving by green covering.更多还原
