摘要
[Objective] The aim was to explore the effects of different leaching solu- tions on yield increasing of rice. [Method] Three rice parents were chosen from dif- ferent areas to treat with leaching solutions and rice leaves were sprayed with leaching solutions in seedling stage and tillering stage, respectively. The test data were recorded. Horizontal and vertical researches were carried out on agronomic traits of rice in different varieties in test or control groups. [Result] The horizontal test showed that hybrid rice parents, submerged with traditional Chinese medicines increased significantly in rice yield and vertical research indicated that rice in control group decreased sharply in yield and in test group improved in both yield and quality, which was also true for following generations. [Conclusion] The test provides references for hybrid rice maintaining rice traits.
[目的]研究不同中药浸出液对稻谷增产的影响。[方法]选取不同地区的3种稻谷亲本,用相应的处理液对其进行处理,分别在其幼苗期,分蘖期向植株叶面喷洒相应的稻谷种子浸泡液,并记录试验数据,通过对不同地区、不同品种、不同组别的农艺性状数值进行横向研究和纵向研究。[结果]横向试验后发现使用纯中药浸出液处理过的杂交稻亲本产量大幅度增加。同步进行的纵向研究表明未用中药浸出液处理的一组稻谷产量急剧锐减。另一组用中药浸出液处理过的稻谷产量、稻穗质量明显提高,其子代的产量、稻穗质量也大幅度的提高。[结论]该试验为杂交稻能够实现"留种"提供了有效的参考依据。
