衢县地处浙西丘陵山区,山垄田多,光照不足,多为冷水田。种植双季稻,早稻产量不高,晚稻不能保证安全齐穗。同时,山垄田连续多年种双季稻加重土壤次生潜育化,物理性质变差,使山垄田变成低产田。为提高山垄田粮食产量,我们于1992～1994年在大洲、全旺等地进行山垄田改制试验,将原冬作
Qu County, Zhejiang Province is located in the hilly mountains, mountain ridge and more, lack of light, mostly cold paddy fields. Planting double cropping rice, early rice yield is not high, late rice can not guarantee safe and full earning. At the same time, the continuous cultivation of double cropping rice in mountain ridge fields aggravated the secondary gobalization of soil and the physical properties deteriorated, making the ridge fields become low yield fields. In order to increase the grain yield of the mountain ridge fields, we carried out the experiment of mountain ridge field reform from 1992 to 1994 on the continents,
