超级稻“强源活库优米”栽培技术与传统栽培技术的比较

Comparison of Super-rice Cultivation Technique Characterized by Enhancing Source and Activating Sink and Conventional Technique

以超级杂交水稻培杂泰丰和华优86为试验材料,在大田正常生产条件下,进行"强源活库优米"栽培技术与传统栽培技术的产量、产量形成规律和经济效益等的比较。结果表明:1)强源活库优米栽培技术减少了分蘖的衰亡,提高了水稻的有效穗数,进而显著增加了单位面积的颖花数。2)强源活库优米栽培技术降低了生长后期水稻叶面积和叶片叶绿素含量的下降幅度,延缓了水稻叶片的衰老进程。3)强源活库优米栽培技术显著地提高了水稻的产量,其中华优86增产19.5%,培杂泰丰增产10.9%。4)强源活库优米栽培技术的经济效益比常规技术提高了18.4%。

Yield formation procedure and economical benefit was compared between Super - rice cultivation technique characterized by enhancing source and activating sink （ hereafter refers to ESAST） and conventional technique （ hereafter refers to CT） in field practice, with Peizataifeng and Huayou86 as receptors. The results as follows： 1 ） ESAST decreased the amount of unavailable tillers, and at meantime increased the amount of available tillers and total grains of unit area. 2） The decrement of leaf area and leaf chlorophyll content was decreased during late stage of super - rice growth, and the senescence of rice was also delayed, as treated with ESAST. 3 ） ESAST significantly increased the yield of Huayou86 and Peizataifeng by t9. 5% and 10. 9%, respectively. 4） Comparing with CT, The economical benefit of ESAST was increased by 18. 4%.
