| Abstract: |
| The purpose of this paper is to find out the regulation of higher yield and its corresponding main(main)agrotechniques applied to the supershortterm upland rice-Qinai as an experrimental material. 4618 Mu were planted at Bao Ding District,Hopei Province.The result indicates that a good harvet,i.e.the average yield of 439.5 jin/per Mu and the highest yield of 811 jin/per Mu,was acquired.The yield constitution at different levels,the plant form,the leaf area and the dynamic of matter production were all analy... |
