土壤是农业生产的基础,土壤肥力的高低直接影响着农作物的产量与农业的发展速度。当前农业生产上普遍存在的问题之一是土壤肥力不高,而西山地区尤为突出。因此,如何培肥地力,加速土壤熟化,迅速提高土壤肥力是西山地区当前农业生产上必须引起重视和亟待研究解决的一个重要问题。一、西山地区生产概况吕梁地区西山9县,包括167个乡(镇),5486个自然村,164.9万人,其中农业人口141.3万人。总面积16115平方公里,耕地494.3万亩。该区沟壑纵横,植被稀少,童山秃岭,土质松散,水土流失严
Soil is the basis of agricultural production, the level of soil fertility directly affects the crop yield and agricultural development. At present, one of the common problems in agricultural production is that soil fertility is not high, while Xishan is particularly prominent. Therefore, how to cultivate fertility, speed up soil ripening, and rapidly increase soil fertility is an important issue which must be paid attention to and urgently needs to be studied and solved in the present agricultural production in Xishan area. First, the production of Xishan Overview Luliang Xishan 9 counties, including 167 townships (towns), 5486 villages, 1.649 million, of which agricultural population of 1.133 million. The total area of 16,115 square kilometers, 494.3 acres of arable land. The ravines aspect of the area, vegetation is scarce, Tong Shan bald ridge, loose soil, soil erosion and strict
