摘要
研究土壤调理剂对水稻产量和土壤性状的影响,结果表明:随着土壤调理剂用量的增加,水稻产量和秸秆量随之增加;高量调理剂和低量调理剂处理比不施调理剂处理水稻的千粒重分别增加4.57%和4.39%,分蘖数分别增加28.6%和21.0%;施用土壤调理剂可以提高土壤pH值,增加土壤碱解氮、有效磷含量。
To study the rational application amount and effect of soil conditioner, this paper studied the influence of soil con- ditioner on rice yield and soil properties. The results showed that with the increasing amount of soil conditioner, rice production and rice straw were increased. 1000 grain weight of high-volume and low-volume of soil conditioner increased by 4.57% and 4.39% than conventional fertilization. Tiller number of high-volume and low-volume soil conditioner were increased by 28.6% and 21.0% than conventional fertilization . Soil conditioner improveed soil pH, soil alkali hydrolyzable nitrogen, available phosphorus contents.
