摘要

摘要通过对一个大麻品种进行为期一年的试验,确定了种植方式(生长密度和修剪),以优化不同用途大麻品种的生产工艺流程。结果表明,降低作物密度和掐枝会导致植株发育较矮。在密集的非挤压作物中,茎高超过180厘米,而植株在上部1/4-1/5部分开始分枝。在单株可用面积较大的非掐枝处理中,以及在掐枝处理中,下部发育出厚度较小的高产枝。不掐枝处理通常能产生较高的茎和纤维产量,当作物密度降低时,茎和纤维产量会增加。所得结果可作为特定用途的不同品种大麻生产技术评价中确定某些处理的依据。

Influence of Crop Density and Pinching on Hemp Plant Architecture and Yield
Summary One-year experiments conducted with one hemp variety were established to determinate the cultivation practices (growth density and pinching) which could be used to optimize the technological process of hemp varieties production for different purposes. The results showed that reduced crop density and pinching result in development of shorter plants. In denser non-pinched crops, the stem is over 180 cm high, while the plants start branching in the upper 1/4-1/5 part. In the non-pinched treatment with a larger area available for individual plants, as well as in the pinched treatments, more productive branches of less thickness develop in the lower parts. The non-pinched treatments generally produce higher stem and fiber yields, which increase when crop density is reduced. The obtained results can serve as a basis for determining certain treatments during the evaluation of production technology for different varieties of hemp intended for specific purposes.
