摘要
为了探寻柿树优质高效的栽培方法,就不同施用方法、不同形态和不同含量的化肥对柿产量的影响进行了试验。结果表明:增施氮、磷、钾肥是提高柿坐果率和单果质量的一种关键措施;施肥的三个关键时期为4月中旬至6月中旬、7月中下旬和秋季;对树体喷肥可有效提高柿产量,喷施的肥料以0.3%的磷酸二氢钾+0.3%的尿素为最佳。
In order to explore efficient cultivation methods for persimmon, effects of different fertilization methods, forms or contents on persimmon yield were tested. The results indicated that raising the three nutritional elements N, P and K is a key way to promote the fruit setting rate and the fruit mass. From mid-April to mid-June, mid-July and autumn were three crucial periods for fertilization. Applying fertilizer to the trunk could efficiently increase persimmon yields, and the optimal fertilization quantity is 0. 3% KH2PO4 with 0.3 % urea.
