【摘要】 研究了根系分区施肥对黄瓜品种"津绿露优"和"中农203"干物质生产的影响.结果表明:与对照相比,在"津绿露优"黄瓜植株标准溶液+半倍标准溶液与大量元素+微量元素施肥处理中,施肥总量分别减少了25%,50%,植株总干重分别减少了8.7%,36.5%,果实干重分别降低了10.5%,35.7%;在"中农203"黄瓜植株2倍标准溶液+清水与1.5倍标准溶液+1/2标准溶液施肥处理中,施肥总量不变,植株总干重分别增加了10.4%,5.6%,果实干重分别增加了22.9%,21.0%.更多还原

【Abstract】 The effect of root-divided fertilization on dry matter production was investigated in cucumber cultivar "Jinlvluyou" and "Zhongnong 203". The results indicated that in comparison to control,in the treatments,standard solution +1/2 standard solution and massive element+trace element for each half of root zone in cucumber cultivar "Jinlvluyou",where the total quantity of fertilizer was decreased by 25% and 50%,total plant dry weight was significantly decreased by 8.7% and 36.5%,and fruit dry weight was by 10.5% and 35.7%,respectively;in the treatments,2 standard solution +water and 1.5 standard solution+0.5 standard solution in cucumber cultivar "Zhongnong 203",where the total quantity of fertilizer was constant,total plant dry weight was significantly increased by 10.4% and 5.6%,and fruit dry weight was by 22.9% and 21.0%,respectively.更多还原
