在不同栽培密度下,对工业大麻品种“云麻1号”产量及农艺性状进行研究,得出了“云麻1号”的最适宜的栽培密度,为大田生产提供科学依据。结果表明,随栽培密度的增加,株高、茎粗逐渐减小,而分枝高度、小麻率逐渐增加;栽培密度过大或过小都会导致工业大麻品种“云麻1号”产量降低。小区产量试验表明,“云麻1号”在中等肥力水平下栽培密度以46.95万株/hm2为宜,干茎杆产量可达15708kg/hm2。
Under different cultivation densities, the yield and agronomic traits of industrial hemp “Yunma 1” were studied, and the most suitable planting density of “Yunma 1” was obtained, which provided the scientific basis for the field production. The results showed that with the increase of planting density, the plant height and stem diameter decreased gradually, but the branch height and the rate of small hemp increased gradually. If the planting density was too large or too small, the output of industrial cannabis variety “Yunma 1” reduce. Community yield test showed that “Yunma 1” at medium fertility level planting density of 46.95 million / hm2 is appropriate, dry stem production up to 15708kg / hm2.
