在广西钟山县回龙镇回龙村以优质常规稻品种黄华占,采用田间小区常规试验的方法,研究了优质常规稻氮肥施用方法对其增产效应的影响。结果表明,在施P2O5 60 kg/hm2、K2O 120 kg/hm2的条件下,氮肥(150 kg/hm2,处理3)在基肥60.0 kg/hm2、分蘖肥60.0 kg/hm2、幼穗分化肥15.0 kg/hm2、壮粒肥15.0 kg/hm2的施用,对优质常规稻增产效应最好,平均产稻谷5449.5 kg/hm2,分别比处理5、处理4、处理2、处理1增产稻谷375.0 kg/hm2、336.0 kg/hm2、429.0 kg/hm2、520.5 kg/hm2,分别增长7.33%、6.57%、8.54%、10.56%。
In Huilong Village, Huilong Town, Guangxi Zhuang Autonomous Region, a high-quality conventional rice variety, Huang Huazhan, was used to study the effects of high-quality conventional rice fertilization on its yield-increasing effect. The results showed that under the condition of applying P2O5 60 kg / hm2 and K2O 120 kg / hm2, the nitrogen fertilizer (150 kg / hm2, treatment 3) was 60.0 kg / hm2 for basal fertilizer, 60.0 kg / hm2 for tillering fertilizer and 15.0 kg / hm2 and granary fertilizer 15.0 kg / hm2, the yield was the best for the good quality conventional rice with an average yield of 5449.5 kg / hm2, which was higher than that of treatment 5, treatment 4, treatment 2, treatment 1 Increased yield of rice 375.0 kg / hm2, kg / hm2, 429.0 kg / hm2 and 520.5 kg / hm2, increased by 7.33%, 6.57%, 8.54% and 10.56% respectively.
