选取辽宁省喀左县后坟村的褐土,于1987～1988年进行定位观测方法进行土壤水分动态研究。结果表明,辽西耕作褐土主要是春旱,有时有伏旱和秋吊。秋末作物收获前,常有部分降雨进入土壤,却经冬春蒸散损失。因此,若能采取合理的农耕措施,进行深松、深翻,增施有机肥,改善土体结构,蓄纳秋雨或冬灌的水分,做到春旱秋防,便可使农业生产得到有效的水分保障。
The cinnamon soil of the Houfen village in Qazuo County of Liaoning Province was selected to carry out the observation of soil moisture dynamics from 1987 to 1988. The results show that the cultivated cinnamon soil in western Liaoning is mainly spring drought, sometimes with drought and autumn hanging. Autumn crop harvest before, often part of the rainfall into the soil, but lost by the winter spring evapotranspiration. Therefore, if we can take reasonable measures of farming, carry out subsoiling, deep plowing, increasing organic manure, improving soil structure, storing moisture of autumn or winter irrigation and achieving spring and autumn fall prevention, we can make agricultural production effective Moisture protection.
