红麻的适应性强,产量高(比苘麻产量高一倍以上).从70年代初就开始引进种植,并在沿淮的怀远、五河、蚌埠郊区形成一定规模,成为我省淮北地区红麻生产基地.红麻对土壤要求不严,管理技术简便,但年年有零星的早蕾、早花现象,1992年由于特殊的因素影响,出现了大面积的早蕾、早花现象,早蕾、早花率达15%～40%,最高达53.8%,严重影响了红麻的产量的质量.本文根据调查材料结合气象因素,对红麻早蕾、早花原因进行探讨并提出技术对策.
Kenaf adaptability, high yield (more than twice as much yield as hemp) .From the early 70s began to introduce cultivation, and in the Huaiyuan Huaiyuan, Wuhe, Bengbu outskirts to form a certain scale, as the province of Huaibei area Kenaf production base of kenaf on the lax requirements of the soil, management is simple, but sporadic early buds every year, as early as the phenomenon of flowers, due to special factors in 1992, appeared a large area of early bud, early flow phenomenon, Early bud, the early flowering rate of 15% ~ 40%, up to 53.8%, seriously affected the yield of kenaf quality.In this paper, according to the combination of meteorological factors and survey materials, kenaf early bud, reason for early flower to discuss and propose technical measures .
