两系杂种小麦绵杂1号高产栽培技术初步研究

Preliminary Study on the High-Yield Cultural Measures of the Two-Line Hybrid Wheat MS1

采用五元二次回归正交旋转组合设计 ,研究了播期、密度、施N、P、K量对两系杂种小麦绵杂 1号 (原代号MS1)产量的影响。结果表明 ,施N量、播期与密度是影响绵杂 1号产量的主要因素 ,播期对绵杂 1号产量的影响尤其突出。播期与密度的互作也显著地影响着绵杂 1号产量。适当迟播与降低播种量有利于绵杂 1号产量的提高。同时得到了绵杂

The effects of sowing date, density(basic seedling),applied amount of N?P 2O 5 and K 2O on the yield of MSl, a new two-line hybrid wheat,were studied. The results showed that applied amount of N fertilizer, sowing date and density were the main factors influencing the yield,especially the sowing date. The interaction of sowing date and density also affected the yield significantly.Properly-late sowing and properly-low density could increase the yield. The concrete cultural measures for high yield were also obtained.
