木薯是热带、亚热带地区重要的高产粮食、淀粉和饲料作物,世界种植面积约1亿7千多万亩,年产量为1亿多吨。我国种植木薯历史悠久,主要产地是广东、广西。此外,云南、福建、四川、贵州、江西、浙江、湖北、安徽、江苏等省亦有少量引种和试种。北移试种实践证明,北纬33—34度以南,年平均温度15℃以上,全年无霜期230—240天以上,种植早熟品种,可获较正常的产量和质量。现将木薯的栽培技术及去毒加工等方法,介绍如下。
Cassava is an important high-yielding grain, starch and fodder crop in tropical and subtropical regions. The world’s planted area is about 170 million mu and the annual output is over 100 million tons. China has a long history of growing cassava, the main producing areas are Guangdong and Guangxi. In addition, Yunnan, Fujian, Sichuan, Guizhou, Jiangxi, Zhejiang, Hubei, Anhui, Jiangsu and other provinces also have a small amount of introduction and trial planting. Tests proved that the north to move to the north 33-34 degrees north latitude, the annual average temperature above 15 ℃, frost-free period 230-240 days throughout the year, planting precocious varieties, can be more than the normal output and quality. Now cassava cultivation techniques and detoxification methods, are described below.
