High Efficiency Cultivation Technologies of Optimum Fertilization with Two Crops and Two harvests in One Year about Watermelon in Greenhouse

Abstract: In order to effectively alleviate the soil continuous cropping obstacle caused by watermelon planting in the greenhouse, reduce the cost of land renting for watermelon growers and the labor for building and dismantling the greenhouse, and improve the utilization rate of the scaffold and the greenhouse film, Dongtai city took of the project that create demonstration counties replacing the chemical fertilizer demonstration county with organic fertilizer as an opportunity, "organic fertilizer + formula fertilizer + water fertilizer integration" optimization fertilization technology was integrated, and the greenhouse spring watermelon - two high-efficiency cultivation modes of continuous cropping of autumn watermelon in greenhouse were promoted. Using this cultivation mode, the output value of two crops was 22 000 yuan per 667 m2, and the net income was 12 500 yuan per 667 m2. Compared with the traditional mode, the application of organic fertilizer was increased, the application of chemical fertilizer was reduced by 20%, and the income increased by 3 200 yuan, which improved the ecological and economic benefits of planting watermelon for farmers.
