采用自然条件分期播种与定光试验结合,研究57份红麻不同类型品种的光温反应特性。结果表明:(一)分五期播种,无论何期播种,供试红麻品种的现蕾期出现在9月中、下旬;播种后约60天;介于上述二者所需日数之间等三类。(二)根据红麻品种的感光感温特性和最短营养生长期,可将供试品种分为12种光温反应类型。(三)不同光长和不同温度对麻株生长速度的影响因品种而异。自播种到现蕾的活动积温变化与品种感温性密切相关。
Using natural conditions staged seeding and light test combined with 57 different varieties of kenaf light and temperature response characteristics. The results showed that: (i) sowing in five stages, no matter what the sowing, kenaf cultivars in the budding stage appeared in mid-September, late; about 60 days after sowing; between the days required between the two Three categories. (B) According to kenaf varieties of photosensitive temperature characteristics and the shortest vegetative growth period, the test varieties can be divided into 12 kinds of light and light reaction types. (C) of different light lengths and different temperatures on the growth rate of Hemp Varieties vary. Activity changes from sowing to squaring are closely related to the temperature sensitivity of cultivars.
