摘 要:2007年早造于广州从化市和增城市采用"3414"设计方案进行田间试验,研究了不同施肥处理对水稻生长及产量的影响。结果表明,从化试点和增城试点推荐施肥处理的水稻产量水平达到5 370 kg/hm2和5 385 kg/hm2,分别处于第二位及第三位;此外,从化试点推荐施肥处理的氮、磷、钾利用率分别达到35.9%、41.0%和43.3%,在所有处理中位居前列。综合分析结果显示,广州地区水稻测土配方施肥推荐的氮、磷、钾配比(N:P2O5:K2O)为1:0.3:0.8,常规优质稻的施氮量为135~150 kg/hm2。A"3414" field trials of 2007 eady rice were conducted in the testing ground of Conghua and Zengcheng, studied the influence of different fertilizer unit on plant growth and the yield of rice. The results indicated that, compare with the other treatments, the recommendation fertilizer's rice yield was in the highest level, the yield of Conghua and Zengcheng testing ground were 5 370 kg/hm^2 and 5 385 kg/hm^2.The use efficiency of N,P,K achieves 35.9%,41.0%,43.3% in the recommendation fertilizer treatments of the Zengcheng testing ground, totality located in the high level. Synthesize various factors, the recommendation allocated proportion of N : P2O5 : K2O is 1 : 0.3 : 0.8,the N quantity executes of the conventional high quality rice is 135-150 kg/hm^2.
