油菜是孟加拉国北部一种重要的油料作物,油菜的生长期比其它任何油料作物都短,但抗旱性较差,十二月底到一月份的干旱,对油菜危害严重,减少叶面积,导致低产。通过溉灌消除干旱,以及供应充足的养分和正确地栽培管理,油菜籽产量将会大大增加。我们这篇报告旨在研究溉灌和不溉灌条件下,施肥对油菜籽粒产量、含油量和与籽粒产量有关的油菜特性的影响,以及溉灌在孟加拉国对油菜栽培的重要性。
Rape is an important oilseed crop in northern Bangladesh. Rape has a shorter growing period than any other oilseed crop, but its drought resistance is poor. Droughts from the end of December to January are particularly damaging to rapeseed, reducing leaf area and leading to low yields . Rapeseed production will increase significantly through irrigating irrigation to eliminate droughts, as well as providing adequate nutrients and proper cultivation management. The purpose of our report is to study the effects of fertilization on rapeseed grain yield, oil content and rapeseed traits associated with grain yield under irrigated and non-irrigated conditions, as well as the importance of irrigating in rape cultivation in Bangladesh.
