摘  要:
在大田条件下研究了不同种植方式与密度对旱作大豆产量和水分利用效率影响。结果表明,地膜穴播处理的产量较露地沟播与露地条播籽粒产量分别增加25.8%、32.5%,水分利用效率较露地沟播与露地条播分别提高11.1%、14.2%。在不同的播种方式下,地膜穴播、露地沟播和露地条播的最适宜密度分别为13.9、22.9和22.1万株/hm2。

摘  要:
The influence of different planting patterns and density on soybean water use efficiency and grain yield were studied through field experiment.The results showed that the yield of the spot sowing with film cover(SSWFC) increased 25.8% and 32.5% than the furrow sowing with film cover(FSNFC) and the strip sowing without film cover(SSNFC) respectively,and water use efficiency of SSWFC increased 11.1% and 14.2% than FSNFC and SSNFC respectively.Under the different planting patterns,the optimum density for SSWFC,FSNFC and SSNFC is 139 000 plants per hm2,229 000 plants per hm2 and 221 000 plants per hm2.
