Taking melon‘Mibao’as experimental material，this paper studied the effect of spraying
Zenggualing with different times on the differentiation of melon female flower buds，fruit position，increasing both
production and benefit．The results showed that the length of internode became obviously shorter，number of side
branches was reduced，and the used labor reduced 120 days per hectare，female flowers occurred continuously
on side branches，and fruit development period shortened 3 days after using Zenggualing．The yield of melon
increased by 11.4% and 19.2%，respectively than the control，after spraying Zenggualing one and two times．
The benefit increased 53 304.15 yuan and 71 592.00 yuan per hectare，respectively．Therefore，reasonable use
of Zenggualing can effectively inhibit the vegetative growth，and promote reproductive growth，thus enabling to
satisfy the production needs for increasing production and benefit，and simplification of cultivation procedure．
