水稻旱育秧施用沼肥的效果

Effects of Marsh Gas Manure on Seedling Quality Raised in Dry Nursery and Yield in Rice

应用沼肥不同用量培肥苗床,进行旱育秧沼肥用量比较试验,结果表明:水稻旱育秧施用沼肥,其秧苗生长情况、秧苗素质、经济性状明显优于常规旱育秧,最高产量650 kg/667m2,比常规旱育秧增产27.4%;在不同施用量中,50 kg床土对未澄清的沼渣混合液20 kg培肥苗床效果最好,其次是15 kg,与其它处理相比,产量差异均达到极显著水平。

The results from the experiment of raising seedlings in dry nursery applied with different amount of marsh gas manure, show that the growth situation, quality and economic characters of rice seedlings raised in dry nursery applied with marsh gas manure are obviously better than those of rise seedlings raised in conventional dry nursery, and the highest yield is up to 650kg/667m, 27.4% higher than CK. The rice yield of the treatment applying 20kg un-filtrated marsh residue liquid in 50kg nursery soil is the best in the tested application amounts and the yield variation among other treatments reaches the significant level.
