内蒙古自治区基本上处于干旱、半干旱地带,为在水、土、光、热等方面创造适于幼苗生长发育的有利的生态环境,因地制宜的在造林前细致整地显得非常重要。整地能提高土壤含水量。据赤峰市郊区水地公社兴隆沟大队大房身生产队1981年测定,大坑整地后在生长期内土壤含水量能提高2.5—4％。整地能提高土壤温度。据大房身生产从1980年4—6月测定,大坑内地温要比坑外高1—3℃,有利于林木生长。整地能增加土壤熟化过程,提高肥力。据赤峰市郊区城子公社
Inner Mongolia Autonomous Region is basically in arid and semi-arid zones. It is very important to create a favorable ecological environment suitable for the growth and development of seedlings in terms of water, soil, light and heat. Soil preparation can increase soil moisture content. According to the suburbs of Chifeng Xinglonggou Brigade Batalong Brigade production team determined in 1981, after the pit pitching in the growing period of soil moisture content can increase 2.5-4%. Soil preparation can increase soil temperature. According to the big body production measured from April to June 1980, the temperature in the pit is 1-3 ℃ higher than the pit, which is good for tree growth. Soil preparation can increase soil maturation process and improve fertility. According to Chifeng suburban Chengzi commune
