为了探讨甘薯夏栽的高产栽培技术,长葛县农业局自1983年开始,对甘薯麦垄套栽技术进行了研究,通过多点试验、示范,找出了小麦田间甘薯的适宜套栽期、密度和栽植方法,经1985年以后连续四年的大面积验证,证明甘薯麦垄套栽比常规栽植的栽期提前25天至一个月,且具有方法简便易行、错开农活、易夺高产等优点。因而有很大的实用价值。可在黄、淮、海流域的甘薯产区推广。
In order to explore the sweet potato summer planting high-yielding cultivation techniques, Changge County Bureau of Agriculture since 1983, the planted sweet potato ridge cultivation techniques were studied by more trials and demonstrations to identify the suitable sweet potatoes in wheat field planted period, Density and planting methods, after 1985 for four consecutive years of large-scale verification that sweet potato wheat ridge planted than the conventional planted 25 days to one month ahead of schedule, and has the method is simple and easy, staggering farming, easy to take high yield advantage. So there is great practical value. In Huang, Huai, Hai Basin sweet potato areas to promote.
