摘 要：
针对呼伦贝尔地区现有免耕播种机行距宽、麦类作物出苗后封垄不好导致水分蒸发快、杂草不易控制、秋收割晒时易掉沟或塌铺以及单位面积土地利用率不高等问题,在现有2BMG-24型免耕施肥播种机基础上进行改造,形成缩垄增行免耕施肥播种机,使种植行距由传统的16cm缩减到10cm,并进行了大麦和小麦的对比试验研究。结果表明:小麦密植播种的株高、穗粒数和千粒质量较常规播种分别减少4.9%,8.3%和0.8%,但每公顷穗数增加了17.6%;大麦密植播种的株高和千粒质量无明显变化,平均每穗粒数减少1粒,但每公顷穗数增加了22.2%。

摘 要：
Ther are some problem that row distance of no-till seeder is wide,grains seedling covering bare soil bad,water evaopration is quick,weeds control is bad,crop falling down easy on harvesting,land use ratio of unit area is lower.Solid seeding no-till planter is reformed by 2BMG-24 no-till seeder.Row spacing is 10cm.The tests on seeding wheat and barly been proceeded.The results indicated that some wheat parameters of solid seeding are reduced than convention seeding,for example plant height,number of grain per ear and thousand seed weight etc.4.9%,8.3% and 0.8% respectively.And some barly plant height and thousant seed weight been no change,number of grain per ear reduced one,but number of ear per acre increased 22.2%.
