摘要:

针对云南高海拔(2 700 m)粳稻产量较低的情况,研究了不同施肥处理对产量及相关性状的影响。结果表明,氮肥后移、前控后促施肥、缓控释肥替代、增施穗肥处理的产量分别为6.50、5.98、5.63、5.57 t/hm2,比对照分别增产24.05%、14.12%、7.44%、6.30%,增产均达显著水平;氮肥后移处理(基肥施腐熟农家肥7.5 t/hm2和复合肥300 kg/hm2,不施分蘖肥,促花肥施尿素45 kg/hm2,保花肥施尿素45 kg/hm2)能促进二次枝梗数的分化,增加群体颖花量,齐穗期倒3叶、倒4叶SPAD差值小,其LAI大,获得最大增产。

Abstract:

The effects of different fertilization treatments on the yield and related traits of high altitude japonica rice (2700 m) in Yunnan were studied because of its low yield. The results showed as follows: the yield of treatments of postponed N-fertilizer application, promoted N-fertilizer after former control, replaced by slow controlled release fertilizer and increased panicule fertilizer were 6.50 t/hm2, 5.98 t/hm2, 5.63 t/hm2, 5.57 t/hm2, and significantly increased by 24.05%, 14.12%, 7.44% and 6.30% compared with the control, respectively. Postponed N-fertilizer application (base fertilizer 7.5 t/hm2 and compound fertilizer 300 kg/hm2, without tillering fertilizer, promoting flower fertilizer applying urea 45 kg/hm2, protecting flower fertilizer applying urea 45 kg/hm2) promoted the differentiation of secondary stem number and increased population spikelets. At full heading stage, the SPAD difference of inverted 3 leaves and inverted 4 leaves was the smallest,and LAI was the largest, which resulted in the maximum yield increase.
