石灰和硼砂对果梅生长结果影响初报

Effects of calx and borax on growth and bearing of plum

针对永泰园艺场果梅立地条件及生长状况,以惯用施肥量(N﹕P2O5﹕K2O = 1﹕1.9﹕1.7,氮磷钾施用量1.83Kg/年/株)为对照,在N、P2O5、K2O 比例均为1﹕0.4﹕0.6的基础上施用不同肥料组合,研究其对果梅生长、结果的影响。试验初步表明,在N、P2O5、K2O 比例为1﹕0.4﹕0.6、氮磷钾施用量1.38kg/年/株的基础上添加石灰和硼砂,与对照相比,硬核期后的坐果率提高9.9%,产量增加14.2%,明显促进新梢生长。有机肥的配施到第二年才产生肥效。

A field experiment was conducted in 2000 to examine the effects of different application rates on growth and bearing of plum. Four treatments were used, including N, P, K fertilizers (N : P2O5 : K2O = 1 : 0.4 : 0.6) 1.38kg/plant/y, N, P, K fertilizers combined with organic fertilizer, with calx and borax, and the control (N : P2O5 : K2O = 1 : 1.9 : 1.7, 1.83kg/plant/y). The results showed that N, P, K fertilizers combined with calx and borax increased the percentage of fertile fruit and yield by 9.9% and 14.2%, respectively, and promoted the growth of new shoots. The effect of organic fertilizers was exhibited in the next year.
