摘要
根据定位田间试验资料,分析了几种耕作法在渭北旱源东部半湿润偏旱区的土壤水分、土壤硬度等效应。结果表明:浅耕深松能显著增加夏闲期土壤贮水量,小麦播种期2m土体比传统耕作法多蓄水20mm。
Based on the data from the field fixed position tests,the effects of soil moisture and soil hardness in the semihumid and liable to drought region in eastern part of Weibei rainfed high-land are analyzed.The results indicate that subsoiling had the effect upon promoting soil waterstorage during summer fallow period,soil water in 2m deep was increased by 20mm more thanthe conventional tillage system in the sowing stage of wheat.
