摘要
通过在自然降水条件下对新修梯田施肥的田间定位试验研究得出：１．不同施肥处理以有机无机配合的产量最高，其次为氮磷配施，单施磷肥产量与对照相当；２．植株生物学性状对不同肥料的反应与产量趋势一致。因配施可增加作物茎叶量，进而提高生物学产量；３．新修梯田增加施肥量，尤其是有机肥用量，并注意与化肥合理搭配。
The field position fertilization test was conductd on new terraced field in the case of natural rainfall,the results showed that(1)in the different treatments,the most significant treatments on yield increase was the mixture of organic fertilizer and inorganic fertilizer,the next was the mixture of nitrogen and phosphours,the yield of only apply phosphours was equivalent to the ckeck experiment.(2)the effects of crop biological characters on the different fertilization were similar with yield's.Because fertilization may increase the amount of stems and leaves,it would increase the biomass.(3)on the new terraced fields,increasing the amount of fertilizer,especially organic fertilizer applied and paying attention to its mixture with chemical fertilizer were the main way for improving water used efficiency and yield of the crops.
