摘　　要：在新建沟坝地引进推广马铃薯种植,并施以化学除草与化学调控,进而对马铃薯主茎数与产量的关系做了一定的探讨。试验表明,播后苗前进行土壤处理,杂草株防效达到95%以上;在初花期采取化学调控,产量可提高39.27%,淀粉含量提高11.21%,并且验证了主茎数与产量具有正相关性的结论。化学除草与化学调控并用,对新建沟坝地马铃薯种植具有较大的推广价值。Potato planting on newly built ditch dam was introduced and chemical weed control and chemical regulation to study the relationship between the number of main stalk and the yield was conducted. The results show that：after sowing before emergence using soil treatment the preventing effect reached above 95% for each plant; in early flowering time, using chemical control, the yield increased 39.27% ; starch contents increases 11.21 percent. The research proves a conclusion that the main stalk and the yield have positive correlation. To use chemical weed regulation and chemical regulation together, there has a big value to promotion of potato planting on new ditch dam.
