施磷量对水稻秧苗素质的影响
|
摘要
为明确磷肥的不同施用量对水稻秧苗素质的影响,选用磷肥(重过磷酸钙)采取随机区组设计进行试验研究。结果表明,磷肥用量49.8 g·m~(-2)的处理叶龄和茎基宽显著高于不施磷肥处理,且秧苗发根力的根长和根数都显著高于不施磷肥处理,但磷肥用量过大,则会抑制发根。因此,在供试土壤条件下,磷肥施用量49.8 g·m~(-2)能有效地增加根数、叶龄,提高水稻秧苗素质,利于插秧后的返青。
Randomized design was used to study the effect of different phosphorus levels on rice seedling. Phosphate fertilizer was selected(Triple superphosphate), the results showed that phosphate fertilizer, in 49.8 g.m~(-2) level of leaf and stem base width was significantly higher than that no phosphorus fertilization treatment, And seedling root length and root number were significantly more than no Phosphorus fertilization treatment, but phosphate amount is too large will inhibit the roots. Therefore, in the tested soil conditions, Phosphate fertilizer can effectively increase the number of root and leaf age in the 49.8 g.m~(-2) level, in order to improve the quality of rice seedling transplanting, and facilitates the regreening,for rice seedling provides theoretical basis for the high yield and good quality rice, laid the foundation.
