我县属温带半干旱大陆性气候,年降水量较少,蒸发量大,干旱严重地限制了玉米产量的提高。经多次试验测得:1千克干沙土吸水达饱和时可吸水2.5升,而1千克泥炭吸水达饱和时较沙土多吸水1.5升。如果沙土地坐水种玉米时施泥炭,可缓解旱情。1990至1992年我们进行了沙土地种玉米施泥炭试验,详细情况报告如下。
My county is a temperate semi-arid continental climate, less annual precipitation, evaporation, drought severely limits the yield of corn. After several tests: 1 kg of dry sand absorbs 2.5 liters of water when saturated, while 1 kg of peat absorbs water up to 1.5 liters more than sand. If the sand to sit when planting corn, peat, can ease the drought. From 1990 to 1992, we conducted a trial of peat charcoal on sandy land, the details of which are reported below.
