| 摘 要： | 目的]探索荃优丝苗高产栽培技术,为其推广提供技术参考。方法]分别设置3种不同的栽插密度和施肥水平,研究大田生产中不同栽插密度与施肥水平对荃优丝苗产量的影响。结果]3种栽插密度的处理间产量存在差异,但均未达到显著水平。其中25.5万穴/hm2移栽密度的处理产量最高,达9764.5 kg/hm2,栽插过稀过密均不利于获得高产。不同施肥水平其产量差异较大。较低栽插密度下,随着施肥量的增加,荃优丝苗产量呈增加趋势;高密度栽培时,施肥不能过多,否则产量会降低。结论]荃优丝苗作中稻栽培,目标产量在10500 kg/hm2左右时,栽培密度为25.5万穴/hm2以内,则适宜的氮肥施用量为225 kg/hm2左右,施肥过多或过少均不利于产量的提高。

| Abstract: | Objective]To explore the high-yielding cultivation techniques of Quanyousimiao to provide technical references for the promotion.Method]Three different planting densities and fertilization levels were set up to study the effects of different planting densities and fertilization levels on the yield of Quanyousimiao in field production.Result]There were differences in yield among three planting densities,but none of them reached significant level.Among them,the highest yield was 9764.5 kg/hm2 with 255000 holes/hm2 transplanting density.Over-sparse and over-dense planting was not conducive to high yield.The yield varied greatly with different fertilization levels.Under lower planting density,with the increase of fertilizer application,the yield of Quanyousimiao showed an increasing trend;but under higher planting density,fertilization should not be excessive,otherwise the yield would be reduced.Conclusion]When the target yield was about 10500 kg/hm2 and the cultivation density was less than 255000 holes/hm2,the suitable amount of nitrogen fertilizer application was about 225 kg/hm2.Too much or too little fertilization was not conducive to the increase of yield. |
