摘要
从荞麦品种优选和产量构成因素上探讨荞麦高产稳产的栽培技术。优选品系“９２０１”具有１５００ｋｇ／ｈｍ２以上的产量潜力。相关和通径分析表明，在适宜播期（８月下旬至９月初）、适宜种植密度（４５～５２．５万株／ｈｍ２）基础上，力争较多的单株粒数和较高的粒重对增产具有重要作用，尤其是单株粒数（γ＝０．９５８１，Ｐ＝１．１４２６）．并由此提出秋播荞麦具体栽培技术措施。
Through screening of excellent lines and analysis of yield components on buckwheat , the paperapproached its cultural techniques for high and stable yield.The best line'9201' was chosen,with yieldpotentiality of more than l500kg/hm2.The suitable sowing period was from the end of August to the first ofbewptelnber and the reasonable planting density was 450000～525000 plants/hm2.The analysis resuIts orcorrelated cofficients and path comcients showed that mu ch more grains per plant and higher l 000 -grainweight played an important role in increasing seed yield, especially seeds per plant(γ=0.9581,p==1.1426).On the basis of above results and other planting experiments,the paper put forward the detial culturaltechniques on buckwheat during fall-sowing.
