  表面上看早稻的种植面积的下降是种植结构调整的结果，虽然早稻种植面积的下降为发展经济作物腾出了一定的种植空间，但通过调查发现，种植业结构调整与早稻种植面积下降没有必然的联系，主要与季节性抛荒有很大的关系。
• Firstly , the concept of cultivated land quality was defined as the integrative character of cultivated land biological capacity and the benefit of plant under the condition of using as plant cash crops , and of cultivated land potential benefit under the condition of use as construction land . cultivated land basic function was defined as subsistence function when used to plant food crops , as benefit function when used to plant cash crops , and as bearing function when used as construction land
  本文首先明确了耕地质量是耕地在现实用途条件下的生物生产能力和农业收益能力与未来用途条件下的潜在收益能力的综合属性特征,并且将耕地的基本功能确定为种植粮食作物的生存功能,种植经济作物的收益功能和用作建设用地这一潜在用途的承载功能。
• Has become one of cash crops of regional scale planting for many years in china . unfortunately , because scallion is planted with a small spacing between seedlings , all kinds of available transplanters made in domestic can not be used for transplanting scallion , so up to now scallion planting has to be planted by manual tools

• The agricultural production holds an important position in baoding area , winter wheat and summer corn are the main grain crops and cotton is the main cash crop . the water resources used in agriculture include rainwater resources used directly by crops and surface water resources or underground water resources which is used through irrigation . there have been lots of rainwater waste because of lacking in research on rainwater resources utilization and in perfect engineering technology in baoding area . to make full use of rainwater is important to alleivate the water resources crisis and improve the ecological environment , the main objectives can make more rainwater turn into soilwater that can be utilized by crops directly and decrease the crops requirments for the surface and ground water resources
  用于农业生产的水资源包括直接利用的雨水资源和通过灌溉补充的地表水资源和地下水资源。目前，保定市对直接用于农业生产的雨水资源尚未进行深入细致的研究，而且雨水资源的利用工程技术措施尚不完备，这种情况造成了雨水资源的浪费。显然，充分利用雨水资源，即尽可能多的把天然降水转化为可被作物利用的土壤水，减少作物对现有水资源(地表水资源和地下水资源)的需求，对于缓解保定市水资源供需矛盾，改善水环境与生态环境有重要的现实意义。
