摘　　要：全生物降解渗水地膜覆盖冬播谷子是一项有机旱作新技术,可以实现“秋雨冬储春用”,缓解长城沿线半干旱生态区常年易发生春夏连旱难播种的问题。采用1300 mm×0.007 mm全生物降解渗水地膜覆盖穴播技术进行冬播谷子多点对比试验,用回归系数法计算各产量结构因子的贡献率。结果表明,各产量结构因子的贡献率为成穗数31.65%,穗均饱满谷籽粒数32.40%,水选后的千粒重35.95%,三者贡献率无明显差异。冬播谷子获得高产采取的技术措施是追施穗肥促进籽粒饱满、加强生育期管理增加穗均饱满谷粒数、加大播种密度增加成穗数。以上结果对提高冬播谷子产量具有指导意义。Winter-sown millet covered full biodegradable water permeable plastic film is a new organic dry farming technology,which can realize“the autumn rain stored in winter is used in spring”,and alleviate the problem of continuous drought in sowing in spring and summer in semi-arid ecological areas along the Great Wall.In this paper,a multipoint comparative test of winter-sown millet was applied with the 1300 mm×0.007 mm full biodegradable water permeable plastic film mulching technique,and the contribution rate of each yield structure factor was calculated by regression coefficient method.The results showed that there was no significant difference in the contribution rates of panicle bearing tiller rate(31.65%),full grains per spike rate(32.40%)and 1000-grain weight rate after water separation(35.95%).The technical measures taken to obtain high yield of winter-sown millet should topdress fertilizer to promote grain plumpness,strengthen the management of growth period to increase the number of full grains per spike,and increase the planting density to increase the number of completed spikes.Above results were of great significance to study the yield structure of winter-sown millet with biodegradable water permeable mulching film to increase the yield of winter-sown millet.
