河北省成安县何横城大队自力更生,艰苦奋斗制造出几种间作套种农机具,都具有“土”的特点:结构简单,使用方便,成本低,工效高,实用价值大。这里简要介绍其中几种。——编者畜力刮畦机适用于粮、棉高低垅种植。刮畦是一项费工多,劳动强度大,技术性高,季节性强的农活。粮、棉单作,畦宽一般是5～6尺。而间作套种畦宽只2尺左右,这就更增加了刮畦的工作量。人工刮畦,每人每天只能刮1亩左右,刮得慢了,幼苗就要出土,一不小心把种子刮出来,还会造成缺苗断垅。这道工序跟不上,就影响间作套种面积的扩大。所以,我们首先集中力量创制了这种刮畦机。
He Chengcheng County, Hebei Province, Ho Heng Shing self-reliance, hard work to create several intercropping intercropping farm machinery, have a “earth ” features: simple structure, easy to use, low cost, high efficiency, practical value. Here are a few of them. - Editor Animal power scraping machine suitable for grain, cotton crop cultivation. Gua Sha is a more labor-intensive, labor-intensive, highly skilled, seasonal farming. Grain, cotton single, wide width is generally 5 to 6 feet. The intercropping 畦 width only about 2 feet, which is even more scraping the workload. Manual scraping, each person can only scraping about 1 acre per day, scraping slowly, the seedlings will be unearthed, accidentally scraping the seeds, but also result in lack of seedlings broken 垅. This procedure can not keep up, it affects the intercropping area expansion. So, first of all, we focused on creating this scraping machine.
