| 摘 要： | 以磷石膏为水稻秧苗床土调酸剂,研究其对水稻秧苗抗性酶活性的影响。结果表明,磷石膏与硫酸混合处理PG4和磷石膏处理PG2、PG3均可使秧苗床土达到适宜水稻秧苗生长的pH值;同时施入磷石膏可使水稻秧苗的抗逆性增强,其中处理PG2、PG4的效果最好。

| Abstract: | Phosphogypsum was used as a pH regulator on paddy soil to study the influence of the anti-enzyme activities in paddy seedling. The result indicated that,the phosphogypsum and sulfuric acid mixed treatment PG4 and the phosphogypsum PG2 and PG3 treatment could all make the paddy shoot seedbed soil to achieve the suitable pH value; at the same time,with the addition of the phosphogypsum,the paddy seedling resistance was enhanced,in which the effect of treatment PG2 and PG4 was the best. |
