【摘要】 小麦沟播集中施肥具有抗旱、耐寒、减轻盐碱化危害和提高肥料利用率等作用,选用2BFG-6(S)谷场施肥沟播机,通过机械化措施实现沟播集中施肥各项农艺要求,特别是旱年豁干种湿抗旱播种,丰水年侧深位集中施肥,提高肥料利用率等性能,一般较平播对照增产14.7～20%。这种沟播机是与8.8～11KW 小四轮拖拉机配套的复式作业播种机具,主要适用于渭北早原中低产区和盐碱化区谷类作物沟播和各种化肥的深施。更多还原

【Abstract】 Furrow seeding with concentratedly-applied fertilizer as a measure to resi-st drought.coldness and injury from salinization and to improve wheat respo-nse to fertilizer is an experience of tranditional agricultural practice innorthern part of winter growing areas in China.With the use of 2BFG-6(S)fertilizing and furrow seeding implement for grains,mechanization makespossible the essential agricultural requirements including furrow seeding andintensive fertilizing.It will be especially beneficial at dry years and in thehumid years,deep side dressing fertilizer efficacy.An increase of 14.7-20% ofproduction is expected.2BFG-6(S)furrow seeder is a kind of compoundoperations combined with a 8.8-11KW four-wheeled tractor adaptable at Wei-bei Rainfed Highland of low productivity or salinization for the furrow seedingof grains and deep application of chemical fertilizers.更多还原
