有机肥不同施用量对水稻产量性状的影响

Influences of Different Amount of Organic Fertilizer on Rice Yields and Related Characters

在施用等量化肥基础上,研究有机肥不同施用量对水稻产量及相关性状的影响。试验结果表明:随着有机肥施用量的增大,水稻群体构成、株高、结实粒数有所增加;有机肥施用量为1 500 kg/hm2时水稻产量最高,为8 044.5 kg/hm2。

Based on the same amounts of fertilizer, this paper studied the influences of different amount of organic fertilizer on rice yields and related characters. The results showed that as the amount of organic fertilizer increased, the rice popula- tion, plant height and grain number increased. When the amount of organic fertilizer reached 1 500 kg/hm^2, the rice had the highest yields of 8 044.5 kg/hm^2. It is indicated that the 1 500 kg/hm^2 organic fertilizer is preferred in the combined appli- cation of chemical fertilizer and organic fertilizer.
