广西大麻种子生产潜力试验初报

为探索籽用大麻高产栽培方案和测试其种子生产潜力。在不同地点设置不同种植密度、施肥用量，分别进行春播和秋播试验，随机排列、三次重复。结果显示春播冬收大麻植株高大，但种子产量较低；秋播大麻植株矮小，但种子产量较高。大麻雌株相对雄株矮而壮，雌雄株数呈一定比例。自然条件下，小区产量与总株数、雌株高、雌株分枝高呈显著正相关。籽用大麻可以考虑秋播冬收，可以引至平原种植，间苗时应拔掉瘦高的植株。要获得种子高产应保证足够苗数。

Preliminary Report on Productive Potential of Hemp Seeds in Guangxi

In order to explore the productive potential and the high - yield cultivation technotogy, the hemp seeds were sowed in spring and summer with different planting densities and fertilizers at different fields, all the tested factors were set up with random arrangement and 3 replicates. The results showed that the plant was tall and the seed yield was low for the seeds sowed in the spring and harvested in the winter. On the contrary, the plant was short and the seed yield was high for the seeds sowed in the autumn. The female plants were relatively shorter and stronger than the male plants, and there was a certain proportion of male to female plants. Under natural conditions, the yield per plot was significantly positive with the total plant numbers, high female plants and female plants with high branches. Seed hemp should be sowed in autumn and harvested in winter, and could be introduced to the plains to be planted, the thin and high plant should be removed during thinning. In order to obtain high - yield, there should be sufficient numbers of seedlings.
