复配育秧基质对水稻生长及籽粒产量的影响

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,CK_1);(3)市售基质(产自江苏淮安,CK_2)。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。

Effects of Compound Matrix for Seedling Culture on Growth and Grain Yield of Rice

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％),soi1(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 Huai'an,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.
