随着我国化肥工业的发展,近年来氮肥在甜菜生产上施用量不断增多,但由于利用率低甜菜增产幅度不大。为提高甜莱对氮肥的利用率,我们探讨了施用氮肥增效剂对甜菜增产、增糖的作用。1976—1978三年试验结果证明:氮肥增效剂ATC(硝化抑制剂)混入氮肥做追肥施入土壤中,可减少氮肥的挥发损失,提高氮肥的利用率;对甜菜有明显的增产增糖作用,可促进甜菜根深叶茂、根体增大,平均根重可增加33.3克,块根产量可
With the development of China’s fertilizer industry, the application of nitrogen fertilizer in beet production has been increasing in recent years, but the yield increase of sugar beet is not large due to the low utilization rate. In order to improve the utilization rate of sweet potatoes on nitrogen fertilizer, we explored the effect of applying nitrogen fertilizer synergist on sugarbeet yield increase and sugar increase. 1976-1978 three years of test results show that: nitrogen synergist ATC (nitrification inhibitor) mixed with nitrogen fertilizer topdressing the soil, reduce the volatilization loss of nitrogen fertilizer, improve the utilization of nitrogen fertilizer; sugar beet significantly increase the role of sugar , Can promote deep leaf beetroot, root diameter increased, the average root weight can increase 33.3 grams, root yield can be
