去秋我省降水量較多,土地板結,土壤湿度較大,部分秋翻地出現明条多,垡块大。虽經早春頂凌耙压整地,各地仍存在着不少坷垃地。据辽阳县各机站服务作业区統計:佟二卜約有3,750亩坷垃地,灯塔約有10,500亩,刘二卜約有4,200亩,柳壕約有4,500亩,沈旦約有3,750亩。尤以低洼易涝土质粘重地区,坷垃地所占面积較大。因此,探討刘二卜公社系列化机耕样板田早春机耕整地中存在的問題,坷垃地形成与防治途径,具有一定的生产意义。 Precipitation in our province to fall more, the land compaction, soil moisture larger, part of the autumn appeared more brightly lit, large block. Although the early spring top rake pressure, there are still many bumps around. According to statistics of service stations in Liaoyang County, there are about 3,750 mu of rubble land in Tong Er Bu, 10,500 mu of lighthouses, 4,200 mu of Liu Erbu, 4,500 mu of Liupu, and 3,750 mu of Shendan. Especially in low-lying waterlogging soil adhesion area, Ke rubbed the larger area. Therefore, it is of great significance to explore the problems existing in the mechanized tillage land preparation, the formation of the rubbish land and the prevention and control measures in the early twentieth century in the early 1960s.
