摘要:
抚远县地处祖国边陲, 白浆土分布面积大, 所占耕地比重高。由于白浆层硬度高达20 ～ 50 kg/cm2 , 阻碍土壤通气透水, 土壤旱涝严重。在深松改土措施上, 能够保持白浆土黑土层位置不变, 使其下的白浆层和淀积层按适当比例混拌的三段式心土混层犁, 可以使心土硬度降低到10 ～ 20 kg/cm 2 , 硬度降低效果保持5 年以上。在国家及省有关方面的大力支持下, 大面积推广三段式心土混层犁改良白浆土, 对于挖掘低产土壤生产潜力, 促进县域经济发展具有重要作用。
Abstract:
The albic soil is largely dist ributed in Fuyuan county.It s subsoil w ith the depth f rom 20cm to 40cm is ext remely hard with the hardness between 20 ～ 50 kg/cm2 and hence , the root depth of major crops like soy beans is o nly 15 -20cm , as a result , w aterlogging and drought occurs f requent ly in the surface soil during the g rowing season .In pract ice , Subsoilers are convent ionally used for the improvement of Albic soil .However , caused of the hig h content of silt in the soil , the soil hardness returns to the previous level just one year af ter operated .A Three -stage Subsoil Mixing plough , w hich can leave the topsoil undisturbed and mix the tw o subsoil layers into one to one ratio , was developed .The soil hardness wi th 10 ～ 20 kg/cm 2 af ter operated by the plough could be maintained for more than five years .With the national support , the large -scale extension of the plough w ill release the potent ial of the product ivity of albic soil and enhance the economic development of Fuy uan county .
