我们1990年在本院试验田内进行了燕麦群体结构的研究。试验品种为丹麦444燕麦。设六个处理(每亩播种量30、40、50、60、70、80万粒。小区面积20m~2。条播,播深5cm,行距20cm。四次重复,随机区组排列。各生育期内测定干物重、叶面系数。苗期测基本苗数,分蘖期测分蘖数,抽穗期测有效分蘖数,开花期测鲜草产量,成熟期测种子产量,用美国产LI-3000叶面积仪测叶面积。试验结果:
In 1990, we conducted a study on the population structure of oats in our laboratory. The test variety is Danish 444 oats. Set six treatments (per acre sowing 30,40,50,60,70,80 million. Community area 20m ~ 2. Broadcasting, sowing depth 5cm, row spacing 20cm. Four repetitions, random block arrangement. The growth period The dry matter weight and the leaf surface coefficient were measured, the number of seedlings at seedling stage, the tiller number at tillering stage, the effective tiller number at heading stage, the fresh grass yield at flowering stage and the seed yield at maturity were measured. Measured leaf area test results:
