玉米、大豆同穴播种对成穴率及产量的影响

Effects of bunch planting of corn with soybean in same hole on crop yield in red soil:

通过推导提出了同穴播种成穴率的理论计算公式。理论计算与试验结果表明 ,同穴播种可以显著提高成穴率 ,红壤旱地玉米、大豆同穴各播 2粒种子 ,成穴率可达 90 %以上。同穴播种既可增产增收 ,又能较大幅度产出蛋白质 。

Theoretical formula of the ratio of holes with seedlings by bunch planting different crop seeds is put out.Based on the formula calculation and field trials,it is obvious that the rate of holes with seedlings can be rapidly increased and it goes up to more than 90% by planting 2 seeds of corn and soybean respectively in the same hole of red soil upland.It can increase dry matter or protein yield.Economic benefits culd be achieved for the farmers.
