无公害西瓜施肥配方筛选试验

Selection of Application Formulation for Watermelon with Pollution-free

为给西瓜种植的最佳施肥配方提供理论参考,2006年在贵州省开阳县花梨乡无公害西瓜生产基地开展了无公害西瓜施肥技术试验研究。结果表明:所设配方西瓜品质均达无公害标准。高量施肥配方(每667 m2施圈肥和沼肥各2 000 kg,尿素21.7 kg,普钙23.8 kg,硫酸钾20.0 kg)产量显著高于中量和低量施肥配方,产投比最高,且可获得最大利润,产量产值均有显著的增加,从获得最大施肥利润考虑,建议采用高量施肥配方。

Three application formulations for pollution-free watermelon were studied to provide the optimum application formulation in Huali village, Kaiyang county in 2006. The results showed that the yield and benefit of applying the high application formulation （2000kg/667m^2 farmyard manure, 2000 kg/667m^2 biogas manure, 21. 7kg/667m^2 urea, 23. 8kg/ 667m^2 calcium super phosphate and 20.0kg/667m^2 potassium sulphate） were significantly higher than other two application formialations. Therefore, the high application formulation should be popularized in production of pollution-free watermelon.
