(1)平整土地在陡坡修筑梯田,平坡筑梗,横坡打垄,农、林、牧用地呈带状相间布局。在平地或被冲出沟的地块,修建灌排方田,有利保土保肥。(2)合理耕作由于表土被冲走,土壤表层太浅,活上层太薄,因此,要逐年适当深翻、深松,打破犁底层,创造一个上松下紧的深厚(25—30cm)耕层,可使土壤成为一个有效的“大水库”和“大肥料库”,这样使蓄水与供水、保肥与供肥、导热与导温、好气与嫌气,使水、肥、热四性协调,为作物高产稳产打下基础。
(1) The formation of land in the steep slopes to build terraces, flat-framed terraces, ridge slope play ridge, agriculture, forestry, animal husbandry was strip-like phase layout. In the flat or washed out of the ditch plots, construction irrigation and drainage Fangtian, beneficial soil and fertilizer. (2) Reasonable farming As the topsoil is washed away, the surface of the soil is too shallow and the top layer is too thin. Therefore, deep plowing and deep plowing should be carried out year by year to break the plow bottom and create a deep (25-30cm) tillage , The soil can become an effective “big reservoir” and “big fertilizer reservoir”, so that water and water, fertilizer and fertilizer, thermal and thermal conductivity, aerosol and anomaly, so that water, fertilizer, hot four Coordination, lay a foundation for high and stable crop.
