作物品种由于遗传型不同,适应自然环境的能力不同。环境使品种的产量在地区及年份间产生波动,但其程度大小因品种而异。我省由于地域辽阔,油菜产区的生态条件差异较大,环境对品种的影响更大,品种分布也很复杂,各区对品种的要求也截然不同。
Due to different genetic types of crop varieties, different ability to adapt to the natural environment. The environment causes the production of varieties to fluctuate between regions and years, but the extent varies by species. Due to the vast territory in our province, the ecological conditions in the rapeseed producing areas are quite different. The impact of the environment on the cultivars is greater and the distribution of the cultivars is also very complicated. The requirements of the cultivars in each area are also quite different.
