夏大豆MN413单产4 726kg/hm2高产栽培技术

摘要

The grain yield of 4 726kg/hm2 of summe r soybean germplasm MN413 with specific characters was harvested in Huanghuai area(Mengcheng county). The morphological characters of MN413 were: stronger root system; high lodging-resi stant; compact plant;luxuriant growth; normal number of pods per main stem but m ore effective pods. The key of super high yield cultivated technique were: stron g seedling and well distributed population had been completed in early duration, then plant growth adjusterment and nutrient translation were made accelerate eff ectively accumulation and increased yield in mid-late duration.%该研究利用具有特异株型的夏大豆高产种质MN413，在黄淮地区（安徽蒙城）获得亩产单产472 6kg/hm2的籽粒产量。其植株形态表现为：根系特别发达，高抗倒伏；株型收敛紧凑；植株繁茂，主茎节数适中，有效节数多。其高产栽培的技术核心是：生育前期抓壮苗匀植群体；中后期抓生长调节和营养运转，促进有效积累提高单产。
