【摘要】 以传统灌溉方式为对照,研究了在北方干旱区的限量控制灌溉对酿酒葡萄-蛇龙珠生长发育和节水效果的影响。结果表明:除灌水量最少的A处理外,B处理和C处理可比对照每生长季节水705 m3/hm2和405m3/hm2,且对葡萄园的土壤含水量、葡萄树的营养生长、光合速率、蒸腾速率、果实产量和质量均无不良影响,对坐果率还有促进作用。更多还原

【Abstract】 Effects of limited irrigation on growth and development of Shelongzhu,a species of brewing grape,and water saving in drought period of North China were investigated comparing with normal irrigation(CK).Results showed: Except A treatment,B and C treatment could save water 705 m3/hm2 and 405 m3/hm2 than CK respectively every year,and had no bad effects to the water content of soil,vegetation growth,fruit quality and yield,photosynthetic rate and transpiration rate,could also increasing the bearing fruit rate.更多还原
