摘要
对甘肃省积石山花椒种植园地的NPK平衡施肥试验研究，结果表明：N与P、K、PK的配施可促进花椒树体新梢的生长发育；其对花椒的结实量性状也有一定的影响；NPK或NPKB配施可使花椒的产量提高为888．4～936.4kg／hm^2，此时产值也达最佳，分别为27505．4～29047．3元／hm^2和26462．9．27948．5元／hm^2。
The balance fertilization on Chinese prickly ash in Jishishan county of Gansu province was studied. The preliminary experimental results showed that the compound fertilizers of N with P, K and PK could promote the growth of new shoot, and had some effects on the yield of fruit. NPK and NPKB had the promising fruit yield of 888.4 ～ 936. 4 kg/hm^2, and the output value were also high, 27 505.4～29 047.3 yuan/hm^2 and 26 462. 9 ～27 948.5 yuan/hm^2 respectively.
