根系分区施肥对黄瓜植株生长与果实产量的影响

【目的】优化植株根系供肥方式,是黄瓜高效栽培的关键。【方法】分别以"津绿露优"与"中农203"黄瓜品种为试材,研究了根系分区施肥对黄瓜植株生长与果实产量的影响。【结果】在黄瓜植株各1/2根区分别采用标准溶液与半倍标准溶液施肥时,施肥总量减少了25%,植株总鲜重与果实产量并没有显著降低;在采用两倍标准溶液与清水以及倍半标准溶液与半倍标准溶液时,施肥总量不变,但植株总鲜重分别显著增加了23.2%和16.6%,果实鲜重显著增加了34.2%与27.1%。【结论】黄瓜根系分区施肥可以达到节约施肥或者增加植株生长量与果实产量的目的。

The Effect of Root-divided Fertilization on Plant Growth and Fruit Yield in Cucumber

OBJECTIVE]Optimizing the method of fertilizing for plant roots is the key strategy for high profitable productionMETHOD]The effect of root-divided fertilization on plant growth and fruit yield was investigated using cucumber cultivar "Jinlvluyou" and "Zhongnong 203" as materialsResult]In the treatment of standard solution 1/2 standard solution for each half of root zone there was no significant reduction in total plant fresh weight and fruit yield although total quantity of fertilizer was reduced by 25%; in the treatment of 2 standard solution water and that of 1.5 standard solution 0.5 standard solution total plant fresh weight was significantly increased by 23.2%and 16.6%, and fruit fresh weight was significantly improved by 34.2%and 27.1%,respectively, though total quantity of fertilizer was constantCONCLUSION]It concluded that it could save fertilizers or improve the plant growth and fruit yield by root-divided fertilization in cucumber.
