定西是全国有名的贫困地区,作物产量低而不稳,这是多方面原因造成的:降水少,分布不均匀,水的利用率不高,每毫米降水生产粮食0.1公斤左右;水土流失严重,土壤肥力下降,蓄水保墒能力降低;热量不足,≥10℃积温仅2050℃,限制了作物对光,水资源的充分利用;本区农民生活贫困,投入辅助能的水平低,尚未完全摆脱原始农业状态。近年来农村认真实行了联产承包责任制,党的政策把经营土地的自主权交给了农民,群众才得以在生产上普遍恢复和采用传统的耕作制。所以认真总结群众经验,发展传统农业,是十分必要的。一、自然和经济条件: 定西地区目前所辖7县中,有6县属陇中18个干旱县范围,定西县具有一定的代表性。
Dingxi is a well-known poor area in the country. The crop yield is low and unstable, which is caused by many reasons: less precipitation, uneven distribution and low utilization rate of water, producing about 0.1 kg of grain per millimeter of precipitation; serious soil erosion, Soil fertility decreased, water storage ability to reduce soil moisture; Insufficient heat, ≥10 ℃ accumulated temperature of only 2050 ℃, limiting the crop light, water resources, full use of the poor living in this area, the level of input auxiliary energy is low, not completely out of the original Agricultural status. In recent years, the rural area has earnestly implemented the responsibility system for remuneration linked to production under the contract of remuneration. When the party’s policy handed over the ownership of the land for operation to the peasants, the masses have been able to resume their general production and adopt the traditional farming system. Therefore, it is very necessary to conscientiously sum up the masses’ experience and develop traditional agriculture. First, the natural and economic conditions: Dingxi region currently under the jurisdiction of 7 counties, 6 counties in Longzhan 18 drought counties, Dingxi County has a certain representation.
