摘要
采用不同的覆膜栽培方式进行试验 ,证明覆膜穴播和膜际条播均能程度不同地改善土壤物理性能 ,提高耕层土壤含水量和土壤温度 ,创造更适合谷子生育的土壤环境 ,从而促进谷子的生长发育 ,增大叶面积和光合势 ,提高光合效率和净同化率 ,增加干物质积累 ,并促进体内物质运转 ,从而提高成苗率、成株 (穗 )率和成粒数 ,实现高产高效 ,高水分利用效率。覆膜穴播栽培方式增产增值 2 3.0 % ,WUE提高 2 3.0 4 % ;膜际条播栽培方式增产增值1 3.4% ,WUE提高 1 2 .95%
Tests were made with different film mulching cultivation methods. The results show that both sowing in holes and drilling along the edges of the film in mulched land can improve the soil's physical properties, increase its water content and temperature and create a better soil condition for the growth of millet by increasing the crop's leaf area and photosynthesis, enhancing the efficiency of photosynthesis and net assimilation and accumulation of dry matters, and thus increasing the survival rate of seedlings, ears and grains. According to statistics, in mulched land sowing in holes can increase the yield by 23.0% and WUE by 23.04%, while drilling along the edges of the film can increase the yield by 13.4% and WUE by12.95%.
