长期以来,葡萄的栽植大都是以机车牵引开沟器开沟,再用人工挖穴后定植。几乎所有的丰产栽培措施都要求把定植穴挖得既大又深(80×80cm),还要求在穴内施有机肥并与表土拌匀,这样做无疑是对葡萄幼树的生长极为有利的。但要挖大穴又施肥拌土,既费劳力,速度又慢且劳动强度亦大。挖一个80×80cm的大坑,仅土方量就有半立方之多。按一般的劳动强度计算,一个人
For a long time, grapes are mostly cultivated by locomotive traction opener ditching, and then manually digging holes after planting. Almost all of the high-yield cultivation practices require digging large and deep planting holes (80 × 80 cm), requiring organic fertilizers in the cavities and mixing them with topsoil, which undoubtedly is extremely beneficial for the growth of young saplings. However, digging large holes and fertilizing the soil, both labor-intensive, slow and labor-intensive. Dig an 80 × 80cm pit, earthwork only have as much as half a cubic. According to the average labor intensity, a person
