贵州雷公山区花魔芋种植的适生环境条件分析

Analysis on Environmental Conditions Suitable for Growth of Flower Konjac in Leigong Alpine Area, Guizhou

根据花魔芋生长发育的基本要求,对照雷公山区的气候资料和土质报道,指出雷公山区海拔600耀1500m区域的生态环境适合花魔芋种植,其中600耀900m、900耀1300m、l300耀1500m依次为次适层、最适层和可适层;深入研究抗耐酸土魔芋种质发现,就近选择凉爽场地扩繁、轮繁种子,能更好适应基地建设就地供种要求;只有应对好酸土锈田、缺磷少钾、春秋低温、凝冻霜害、连作障碍的不利影响,拓展间作、套作,魔芋基地才能有望稳步扩大并实现高产优质.

According to the basic requirements of flower konjac growth, this paper showed that the eco -environment around 600 to 1 500 m area above sea level was suitable for growth of flower konjac, based on the climatological data and soli texture report of Leigong Alpine area. Among them, the 600 to 900 m, 900 to 1 300 m and 1 300 to 1 500 m area above sea level were followed by the less appropriate layer respectively, the most suitable layer and the appropriate layer. Further study was carried out on the germplasm of konjak that be resistant to acid soil. Choosing the nearest nice and cool ground for seed expanding and alternate propagation could better meet the seeds supplying requirements of the base construction. When dealing with the adverse effects of acid and rust soil, phosphorus and potassium deficiency, low temperature in the spring and autumn period and continuous cropping obstacle, konjac base is expected to steadily expanding with high yield and good quality by promoting the intercropping and the relay intercropping mode
