| 摘 要： | 对新乡市四区六县（凤泉区、红旗区、卫滨区、牧野区、获嘉县、原阳县、封丘县、延津县、新乡县、长垣县）的各种土壤类型田间持水量抽样调查结果表明：1.不同质地土壤的耕层（0～20 cm）田间持水量不同,砂土田间持水量范围8.45%～11.30%;壤土田间持水量范围11.49%～26.90%;粘土田间持水量范围24.83%～32.53%;2.相同质地土壤不同层次的田间持水量也不尽相同,砂土20～40cm土层的田间持水量7.23%～9.57%,40～60 cm土层的田间持水量9.88%～10.71%;壤土0～20 cm土层的田间持水量14.84%～25.78%,40～60 cm土层的田间持水量11.49%～26.90%;粘土20～40 cm土层的田间持水量24.83%～27.80%,40～60 cm土层的田间持水量32.16%～33.12%.

| Abstract: | The field capacity of different soil texture in Xinxiang city（including Fengquan district,Hongqi district, Weibin district,Muye district.Huojia county,Yuanyang county,Fengqiu county,Yanjin county,Xinxiang county, Changyuan county） was studied through the sample survey method.The results were as follows;The field capacity in 0～20 cm soil layer for different soil texture was different.and the field capacity in 0～20 cm soil layer of sandy,loamy, clay soil was 8.45%～11.30%,11.49%～26.90%,24.83～32.53%,respectively.The field capacity in different soil layer for the same soil texture was different.The field capacity in 20～40 cm,40～60cm soil layer for sandy soil was 7.23%～9.57%,9.88～10.71%,respectively,and in 0～20 cm,40～60cm soil layer for loamy soil was 14.84%～25.78%,11.49～26.90%.respectively,while in 20～40 cm,40～60cm soil layer for clay soil was 24.83%-27.80%,32.16 -33.12%, respectively. |
