近几年来,泗县农民为充分利用地力,提高单位面积产量,采取了在山芋地里套种玉米的方法。据典型調查和同老农座談,一般均比单栽山芋或单种玉米增产。1956年,长沟乡阴陵高級农业合作社,十四点六亩春山芋套种玉米,結果亩产山芋一千七百六十斤、玉米一百九十五斤,比单栽山芋或单种玉米增产二至三成。泗县农場早在1956年曾作試驗,二亩四分春山芋套种玉米,結果亩产山芋三千一百斤、玉米二百八十四斤,两者合計,比单种玉米或单栽山芋均增产30%以上。在山芋地里套种玉米,由于两种作物均比单种的稀些,通风透光好。同时,一个在上面,一个在下面,在空間上二者互不影响。山芋套种玉米,在播种和管理上有先有后,可以調节劳动力的忙閑。
In recent years, Si County farmers to make full use of fertility, improve yield per unit area, took the method of interplanting corn in the potato fields. According to the typical survey and discussion with the peasants, generally more than single planted or single corn yield. In 1956, Longgouxiangxianling advanced agricultural cooperatives, 14.6 acres of spring taro intercropping corn, the results of mu produce potato 1,700 pounds, 195 kilograms of corn, single-planted potato or single corn Yield two to three into. As early as 1956, Si County Farm had been experimentally tested with two-acre quarters of spring taro intercropped with corn. As a result, the output of mu yang rice reached 3,100 kilograms and that of corn reached 284 kilograms. All potato yield more than 30%. Interplanted corn in the field, because the two crops are thinner than a single, good ventilation and light. At the same time, one above and one below, spatially do not affect each other. Yam intercropping corn, sowing and management of preconceived, you can adjust the workforce busy.
