摘要 [目的]研究不同基質對水稻秧苗素質和水稻生長及籽粒產量形成的影響。[方法]試驗設置3種育秧基質處理:①采用高度腐熟的養牛場墊料為基礎材料(50%),配以蛭石(20%)、泥炭(10%)、土壤(20%)及保水劑適量;②市售基質(產自江蘇鎮江,CK1);③市售基質(產自江蘇淮安,CK2)。分析育秧基質對秧苗素質、水稻生長、產量的影響。[結果]試驗基質能夠滿足水稻育秧壯苗要求,移栽后水稻活棵快,無明顯緩苗期,在其他各項管理措施完全一致的條件下,試驗基質處理比兩對照基質處理水稻分別增產近6%和2%。[結論]該研究為水稻育秧基質的選取提供了參考。

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.

水稻缽苗機插秧技術省工節本,既可以大量消納農業廢棄物,又可以節省育苗營養土取土困難的問題,目前該項技術推廣速度較快[1-3]。采用農民混配的營養土育秧,由于缺乏標準化的操作規范,營養土配制質量往往不夠穩定,難以保證育秧品質和機插質量[4]。隨著水稻高產、高效、輕減、低耗、環境友好要求的不斷提高,規模化、標準化基質育秧和統一高質量機插,已經成為水稻栽培方式的發展趨勢[5-8]。充分利用富含有機質和各種養分的養殖場廢棄物,無害化處理后開發育苗基質已成為目前環保和農學領域的研究熱點[9-11]。但近年來,基質育秧也出現了一些安全問題,基質燒苗現象時有發生[12-14]。該研究在實……
