不同制剂处理对水稻秧苗素质的影响

盆栽试验结果显示,用漯效王1 000、1 200、1 500、2 000倍液浸种甬优12(籼粳杂交稻)和中浙优1号(籼型杂交稻)种子,2个水稻品种的种子发芽率、根长、胚芽长均与清水对照无明显差异。在不施化肥的情况下用漯效王喷施叶面,2个品种的株高、根长、地上部鲜质量、地下部鲜质量、叶绿素相对含量与清水对照也无明显差异。在对处理组施尿素后用漯效王喷施叶面,而对清水、普绿通、可杀得叁仟处理组只施尿素的情况下,漯效王处理的水稻株高、地上部鲜质量、地下部鲜质量、叶绿素相对含量明显优于清水对照、普绿通、可杀得叁仟处理。叶面喷施后14d,漯效王处理组各指标依旧优于对照组。综合试验结果表明,漯效王在与尿素配合施用的情况下能够达到促进肥效、抗虫、促进根部和植株生长、促进分蘖的作用,并且药效持久性好。

Effects of Different Treatments of Preparation on Seedling Quality of Rice

The results of pot experiments showed that there were no significant difference of the seed germination rate, root length and plumule length of hybrid combination Yongyou 12 and Zhongzheyou 1 when the seeds were treated with Luoxiaowang dilution suspen-sion. There were also no evident difference of the seedling height, root length, fresh weight of overground part and underground part when the seedlings were sprayed with Luoxiaowang but without combined using of nitrogen fertilizer. However, when Luoxiaowang was sprayed after application of urea fertilizer, the plant height, fresh weight of overground part and underground part, and chlorophyll content were significantly higher than the treatments with Pulvtong, Keshade-3000 and the blank control (fresh water) after 10 day application. In conclusion, the experimental results indicated that the conbination of Luoxiaowang and urea could improve the fertilizer efficiency, rice resistance to pests, promote the growth of roots and plants, improve tillers of rice, and has long durability of efficiency.
