不同有机物料水稻育秧基质的持水性 及对水稻秧苗素质的影响

为探讨不同有机物料水稻育秧基质的持水性及对水稻秧苗素质的影响,以‘龙稻11号’为供试品种,采用秸秆和稻壳为有机物料与有机肥、草炭、沸石、蛭石、细河沙、碳粉等按不同配比混合,进行有机物料育秧基质的水稻育秧试验。结果表明,有机物料育秧基质的容重与最大持水量呈极显著负相关、不同有机物料育秧基质的失水率在一定范围内都可以满足育秧要求。CO1C为最优基质,基质栽培期间无病虫害发生且所育水稻苗素质最好,达到壮秧效果。利用有机物料配制的育秧基质符合机插秧苗的要求且具有良好的壮秧效果,可以代替普通土壤应用于水稻育秧生产中。

Rice Substrate Water Holding Capacity of Different Organic Materials and Its Effect on Seedling Quality

Rice substrate water holding capacity of different organic materials and its ettect on seedling quahty were studied through rice seedling pot experiment. In this paper, ＇ Longdao 11 ＇ was taken as the test material, and straw and rice husk as organic materials which were mixed with organic manure, peat, zeolite, vermiculite, fine sand, carbon powder, etc. by different proportions, and rice seedlings organic materials substrate tests were conducted. Results showed that, the density of organic materials seedling substrate and water holding capacity was obtained. The use of organic materials substrate could meet requirements of rice seedlings transplanting, and would be applied to rice seedling production and had a good effect, which could replace soil of ordinary rice seedling.
