用甘蓝型油莱(Brassica napus L.)扬油一号供试,主试验采用裂区设计,设不同剪叶处理作验证试验。经密度-产量因素的多重分析指出,欲突破目前产量水平,又能降耗、节本,似应摈弃常规密度(1万株/亩左右)而代之以高密度(2万株/亩左右),提出以提高种植密度的方法创造5—7个一次有效分枝的紧凑型株体,以发挥群体角果的生产优势。
With Brassica napus L. oil (Brassica napus L.) Yang for the first test, the main test using the split design, set different cut leaves for validation test. According to the multiple analysis of density-yield factors, if we want to break through the current production level and reduce consumption and save costs, it seems that we should abandon the conventional density (around 10,000 plants / mu) and replace it with high-density plants (about 20,000 plants / ), Proposed to increase the planting density of the method to create 5-7 primary effective branches of compact strains, in order to give play to the production advantages of the population of pods.
