| 摘 要： | 在翻压紫云英33750 kg/hm2的田块上,适量减少化学肥料施用量,通过田间试验研究不同施肥方法对后茬水稻产量、品质及土壤性状变化等的影响,探求紫云英与化学肥料的最佳配比组合及最佳施肥方法。试验结果表明:翻压紫云英33750 kg/hm2可减少40%～60%的化肥用量,但以减少40%化肥用量,且化肥以基肥∶分蘖肥∶穗肥=2∶5∶3施用,对水稻产量和品质最有利。

| Abstract: | In order to explore the optimum allocated proportion and the optimum application method of Astragalus sinicus and chemical fertilizer,the effects of different fertilization methods on rice yield,quality and soil characters were studied through field test by properly reducing the dosage of chemical fertilizer in the rice field of overturning 33750 kg/hm2 Astragalus sinicus.The results showed that the dosage of chemical fertilizer could be reduced by 40%~60% when 33750 kg/hm2 Astragalus sinicus was used as gr... |
