| 摘 要： | 对原垄卡种与传统耕作种植玉米进行了比较研究。结果表明:在玉米整个生育期,原垄卡种的株高、干物质和叶面积指标整体略高于传统耕作;生育前期原垄卡种的土壤含水量均高于传统耕作,在灌浆期0~10 cm土层传统耕作的土壤含水量略高;而原垄卡种不同生育时期的土壤容重整体低于传统耕作;原垄卡种较传统耕作表现为增产,增产幅度为6.3%。

| Abstract: | The comparative study on maize planted by original ridge tillage and traditional tillage was conducted.The results showed that maize＇s plant height,dry matter and leaf area of original ridge tillagewa were higher than thoes of traditional tillage in the whole growth period.Soil moisture of original ridge tillage in different soil layers was higher than that of traditional tillage in earlier growth period,but in 0~10 cm layer soil moisture of traditional tillage was higher in filling stage;soil bulk density of original ridge tillage was lower than that of traditional tillage;The yield of original ridge tillage was higher than that of traditional tillage,the increasing rate was 6.3%. |
