在四川盆地中部,利用稻—麦两熟田水稻收后,小麦播种之前的70～80天空隙时间,增种一季秋甘薯,一般可亩产薯块1000公斤左右,产藤叶1000～1500公斤。是增产粮食、解决生猪青饲料来源的有效途径。根据历年来的试验资料和群众经验,种秋甘薯必须抓住以下技术环节。一、良种如以获得高额薯块产量为目的,宜选用早熟种宿芋1号、西充黄心为宜;如以粮、饲兼用为目的,以选用生长势旺、藤叶、薯块产量均高的中
In the central part of Sichuan Basin, paddy-wheat double-paddy fields were harvested for the first time in 70- 80 days after the paddy was harvested. One-seasons autumn sweet potato was added. Generally, 1000 kg of sweet potato per mu and 1,000-1,500 kg of vine leaves were produced per mu. It is an effective way to increase grain output and solve the source of live pig fodder. According to the experimental data over the years and the masses experience, autumn sweet potato must grasp the following technical aspects. First, the elite as to obtain high yield of potato for the purpose, should use early maturing seedlings taro No. 1, Xibei yellow heart appropriate; such as grain, feeding purposes for the purpose of selection growth vigor, vine leaves, potato High yield
