摘要
研究了小麦全膜覆土穴播栽培技术的最佳播种密度。结果表明:中密度处理的单位面积穗数适中,群体能够合理的利用有限的光、肥、水等资源,并且群体中单个植株都能正常生长,其群体产量也较高,所以播种时应以中密度为宜,即播种量大约为405万株/hm2。
The best planting density in soil over film-mulched and bunch-seeded wheat was studied.The results showed that the spike number per unit area of middle-density was moderate since the use of limited light,fertilizer,water and other resources was reasonable,the single plant grew better,the population yield was also higher.Therefore,it was appropriate that the planting density was approximately 4,050,000 plants/hm2.
