- 摘要:
- 运用作物有效营养面积理论,对大豆主产区黑龙江省中部垄作主栽大豆品种的有效株行距进行了试验研究与理论解析。研究表明黑龙江省中部地区的大豆有效株行距为47.0~63.0 cm。据此阐明目前生产上广泛采用67~70 cm的垄作,已超过了大豆的有效株行距,造成了土壤资源的浪费。采用55 cm左右的垄距种植大豆,将会更有利于大豆群体产量的提高。该理论为目前黑龙江省北部地区栽培面积逐渐增大的大豆窄行垄栽培提供了有力的理论根据。
- Abstract:
- With the theory of crop’s effective nutrient area,an experiment was conducted to identify whether effective plant and row spacing(EPRS) was suitable for soybean production.The results showed that EPRS of soybean was 47.0~63.4 cm in the central of Heilongjiang province.Therefore the 67~70 cm of ridge width in the present farming system has exceeded EPRS,which could waste soil resources.It was suggested that 55 cm of the row width of soybean should be benefit for the increase of population yield,especially in the central and south of Heilongjiang province.This theory provided a scientific evidence for the increasing area of narrow ridge farming system in the north of Heilongjiang province
