摘　　要：为了解决贵州省台江地区主产的红油大板栗空棚、低产问题 ,对台江红油大板栗低产栗园进行了施肥试验。结果表明 ,单独施氮虽能提高树体的氮含量 ,但并不能提高磷、钾元素的含量和板栗的产量 ;施磷能够极显著地提高板栗新梢叶中氮、钾元素的含量 ;施磷、配施氮与磷以及配施氮、磷、钾的板栗 ,新梢叶中磷元素含量极显著提高 ,空棚率极显著降低 ,产量极显著增加 ;施磷对提高台江地区红油大板栗产量的效果显著。文中还就严重缺磷和较缺硼的土壤条件下 。Effect of applying the nitrogen, phosphate, kalium on nutrient condition and yield of chestnut (Castanea mollissima BL. cv. Taijianghongyoudabanli) plant in Taijiang county of Guizhou province were studied. The results showed that the content of N in leaves of chestnut plant increased significantly after applying the nitrogen,but the contents of P, K in leaves and yield of chestnut did not increase. After applying the phosphate, the contents of P and K in leaves increased significantly. In three different treatments, the phosphate , the nitrogen and phosphate the nitrogen, phosphate and kalium, the contents of P in leaves and yield of chestnut increased significantly and the rate of empty seededness decreased significantly. Effect of the phosphate on increasing yield of the chestnut was very significant. How to increase yield of the chestnut in soil of deficiency of P and B was discussed in the paper.
