| 摘 要： | 使用经过改进的免耕直播机,进行了夏玉米免耕直播、耙茬播种和耕翻播种三种不同方式的对比试验。试验分两个阶段,第一阶段主要解决免耕直播(条播、播后还需人工间苗)。第二阶段使用由西德引进的自动检拾装卸车,茎杆粉碎机和免耕点播机(由精量点播机改装而成)解决腾地和免耕点播的机械化。六年的试验结果证明,免耕直播与其他两种方式相比,在播种日期相同的条件下,产量无显著盖异,而且还有以下好处:1.可以提早播种1—2天。2.有抗旱、防涝的作用。3.有利于密植抗倒伏。4.节能省工,提高经济效益。

| Abstract: | To perform the direct seeding in the stubble field after wheat har- vesting,a direct seeding unit has been tested,modified and developed. Assembled to an ordinary drill,this unit is used as a direct drill. The field experiments were carried out in three seeding ways: 1.direct seeding without plowing with direct drill described above; 2.seeding after harrowing with ordinary drill;and 3.seeding after plowing and harrowing with ordinary drill.The aim of these field experiments was to compare the direct seeding... |
