摘要
研究了不同盘土及草炭配比对水稻秧苗素质的影响,结果表明,草炭具有明显改善盐碱土的作用。不同盐碱度的土壤和草炭配比对水稻秧苗素质影响显著。土壤盐碱度越大,秧苗素质越差;增加土壤中草炭比例,秧苗素质提高,但增至一定程度后,秧苗素质不再提高,甚至个别指标有下降趋势,而且盐碱度不同的土壤和不同配比的草炭对秧苗素质有很强的互作效应。
Effect of different tray soil and proportion of peat on seedling quality of rice was studied. Results indicated peat could improve seedling quality of rice significantly. Seedling quality which grew in the lower alkali-saline soil was better than others. Increasing the proportion of peat could improve the seedling quality. However, when it was up to some degree, the seedling quality descended. And the interaction of alkali-saline soil and peat proportion had a significant influence on seedling quality of rice.
