摘要 [目的]研究不同基质对水稻秧苗素质和水稻生长及籽粒产量形成的影响。[方法]试验设置3种育秧基质处理:①采用高度腐熟的养牛场垫料为基础材料(50%),配以蛭石(20%)、泥炭(10%)、土壤(20%)及保水剂适量;②市售基质(产自江苏镇江,CK1);③市售基质(产自江苏淮安,CK2)。分析育秧基质对秧苗素质、水稻生长、产量的影响。[结果]试验基质能够满足水稻育秧壮苗要求,移栽后水稻活棵快,无明显缓苗期,在其他各项管理措施完全一致的条件下,试验基质处理比两对照基质处理水稻分别增产近6%和2%。[结论]该研究为水稻育秧基质的选取提供了参考。

Abstract [Objective] To research effects of different compound matrix for seedling culture on seedling quality ,growth and grain yield of rice.[Method] Experiment set 3 treatments of compound matrix for seedling culture:①Cattle farm padding was taken as fundamental material(50%) with vermiculite(20%),peat coal(10%),soil(20%),and proper water retaining agent addition.②Matrix was saled in the market(produced in Zhenjiang,Jiangsu,CK1).③Matrix was saled in the market (produced in Huaian,Jiangsu,CK2).Effects of matrix for seedling culture on seedling quality ,growth and grain yield of rice were analyzed.[Result] Experimental matrix could cultivate strong seedling,the rice grew quickly,there was not obvious transplanting seedling stage.The yield of experimental matrix treatment was higher than 2 control matrix treatments nearly 6% and 2% respectively.[Conclusion] The research could provide reference for choosing matrix for seedling culture.

水稻缽苗机插秧技术省工节本,既可以大量消纳农业废弃物,又可以节省育苗营养土取土困难的问题,目前该项技术推广速度较快[1-3]。采用农民混配的营养土育秧,由于缺乏标准化的操作规范,营养土配制质量往往不够稳定,难以保证育秧品质和机插质量[4]。随着水稻高产、高效、轻减、低耗、环境友好要求的不断提高,规模化、标准化基质育秧和统一高质量机插,已经成为水稻栽培方式的发展趋势[5-8]。充分利用富含有机质和各种养分的养殖场废弃物,无害化处理后开发育苗基质已成为目前环保和农学领域的研究热点[9-11]。但近年来,基质育秧也出现了一些安全问题,基质烧苗现象时有发生[12-14]。该研究在实……
