甘薯、玉米都是旱地高产作物。在旱地上实行甘薯玉米間作是貫彻“多种高产多收”方針的有力措施,增产潛力很大。为了明确甘薯玉米間作的增产效果和探討相应的栽培技术,我們曾在紹兴嵇东公社农場及五一、五联、翻身、謝家湾等生产队等地进行調查。茲将結果初步报告如下。甘薯玉米間作在紹兴山区已有悠久的历史。过去,多以生产玉米(土名六谷)为主,玉米地中嵌插甘薯的称为“谷地生薯”。解放后,間作面积日益扩大,并且逐漸由以玉米生产为主轉为以甘薯生产为 Sweet potatoes, corn are high-yield crops in dry land. The implementation of sweet potato intercropping in the dry land is a powerful measure to implement the principle of “multiple crops with high yield and multiple harvests”, and has great potential for increasing production. In order to clarify the yield-increasing effect of sweet potato and corn intercropping and to explore the corresponding cultivation techniques, we conducted surveys on the farm of Qiongdong Commune in Shaoxing and the production teams such as 51st, 5th, over and Xiejiawan. The preliminary results of the report are as follows. Sweet potato intercropping in Shaoxing has a long history. In the past, mostly in the production of corn (native name Liu Valley) mainly corn planting sweet potato called “Valley potato.” After the liberation, intercropping area is expanding day by day, and gradually from corn production to sweet potato production as
