摘要: 以临稻16为材料,研究了腐植酸控释水稻免追肥对机插水稻(Oryza sativa L.)产量和经济效益的影响。结果表明,施用腐植酸控释水稻免追肥显著影响产量及产量构成因子,与常规施肥处理(CK)相比,能够减少机插水稻无效分蘖,提高成穗率,增加有效穗数,全生育期供肥平衡,后期无早衰。实际产量随腐植酸控释水稻免追肥用量的增加而增加;经济效益则随施肥量的增加先增加后减少,施肥量为1 050 kg/hm2时效益最高,但后期水稻出现部分倒伏,存在减产风险,施肥量900 kg/hm2的处理群体最优,无倒伏,效益略降低,因此,腐植酸控释水稻免追肥在山东省临沂库灌稻区适宜用量在900~1 050 kg/hm2

Abstract: The effects of humic acid controlled release fertilizer on the yield and the economic benefits of mechanical transplanted rice(Oryza sativa L.) were studied with Lindao 16. The results showed that the application of humic acid controlled-release fertilizer could significantly influence the yield and yield components. Compared with the conventional fertilization (control treatment), it could reduce the ineffective tillers of mechanical transplanted rice, increase the percentage of productive tiller, increase the number of productive panicle, balance the fertilizer supply in the whole growth period, and was no premature in the later period. The actual yield increased with the increase of the amount of humic acid controlled-release fertilizer. Economic benefits increased first and then decreased with the increase of fertilizer application. When the amount of fertilizer was 1 050 kg/hm2, the benefits was the highest, but in the later stage, partial rice appeared lodging and the risk of yield decline. The treatment group with the fertilizer amount of 900 kg/hm2 was the best, no lodging, the benefits was slightly lower. Therefore, the amount of humic acid controlled-release fertilizer in Linyi rice area of Shandong province was within the range of 900 to 1 050 kg/hm2.

Key words: humic acid controlled-release fertilizer, rice(Oryza sativa L.), yield, economic benefits
