土壤有机质含量对水稻苗期生长的影响

Effects of Soil Organic Matter Content on Seedling Growth of Rice

试验选用水稻土、菜地土、深层土3种不同有机质含量的土壤栽培水稻,探究土壤有机质含量对水稻苗期生长的影响。结果表明:土壤有机质含量对水稻发芽影响较小,对发芽后苗期生长影响较大;土壤有机质可促进水稻根茎叶生长;苗期各农艺性状指标表现为水稻土组>菜地土组>深层土组。

In order to research the effects of soil organic matter content on rice seedling growth,3 types of soil,paddy soil,vegetable soil and deep soil,with different organic matter contents were set for rice cultivation. The results showed that the soil organic matter content had little influence on seed germination while greater effects on seedling growth of rice. The soil organic matter could promote the growth of root,stalk and leaf of rice. All the agronomic traits of rice seedlings appeared as paddy soil group vegetable soil group deep soil group.
