摘要:
在大田栽培条件下，以不同的品种和氮肥等肥料的施入研究了5种栽培模式，即品种为长武134（T1）、长旱58+追氮肥75kg/hm2（T2）、长旱58+追氮肥75kg/hm2+有机肥4 500kg/hm2（T3）、长旱58（T4）、长旱58+有机肥4 500kg/hm2（T5），对黄土高原地区小麦干物质的积累、转运和分配的影响。结果表明：干物质量随灌浆的进行而呈增长趋势。T3花前干物质输出率及其对籽粒的贡献率比T4分别高8.54%、11.44%，差异达到显著水平。T4花后干物质转运对籽粒的贡献率最高，为80.85%。花后干物质对籽粒的贡献率显示T4最高，其值为80.85%，T1、T2、T5无显著差异，其值分别为77.97%、77.06%、77.65%。T3能促进灌浆期小麦干物质的积累并获得较高的产量。
Abstract:
Research on dry matter accumulation and transportation on the Changwu Tableland of China,the field experiments were conducted on the five different cultivation models,i.e.,Changwu134(T1),Changhan58+top dressing 75kg/hm2(T2),Changhan58+top dressing 75kg/hm2+organic fertilizer,organic fertilizer 4 500kg/hm2(T3),Changhan58(T4),and Changhan58+organic fertilizer,organic fertilizer 4 500kg/hm2(T3).The results showed as following:dry matter accumulation amount gradually increased during grain-filling period.After anthesis period,dry matter accumulation and contribution rate to grain weight showed that T4 was the highest,reached to 80.85%,T1,T2,T5 reached to 77.97%,77.06%,77.65% respectively.And there were no significant difference among the three treatments.T3 were promoted dry matter accumulation of grain filling stage and get the highest yield.
