丘陵地区常看到这种情况,在冲田的同一块田里(一般2—4亩),三麦往往长得很不一致,特别是里、外坎之间三麦长势尤其悬殊。贫下中农说:“里坎与外坎,产量差一截”。为什么会产生这种现象呢?针对这个问题,我们在本公社有关大队进行了调查研究,调查地区的土壤多为马肝土。 Hilly areas often see this situation, in the same field in Okita (usually 2-4 acres), three wheat tend to look very inconsistent, especially in the ridge, the gap between the outer ridge is particularly disproportionate. The poor middle peasants said: “Likan and the ridge, the output difference of a section.” Why does this happen? In response to this question, we conducted a survey on the brigade in the commune. Most of the soil in the surveyed area was Ma Gan soil.
