- Title:
- Review of Technical Approaches of Increasing Crop Yield in Dryland Farming
- 摘要:
- 本项研究评价了固原、彭阳两县旱地农田的现实生产潜力，进行了两县的旱地农业分区，制定了农田种植制度改革方案。通过三个试区4～6年的验证性实验表明：该地区粮食生产存在很大潜力，可以实现粮食基本自给，影响潜力发挥和达到自给的主要限制因素是土壤肥力不足。为提高土壤肥力，当务之急是增加化肥投入，从长远看，应实行“退耕、改制、种草、还牧”，走农牧业结合的发展道路。
- Abstract:
- The practical production potential of dryland farmland in Guyuan and Pengyang counties were evaluated in this research.The divisions of dryland farming in these two counties was done and the reform decision of cropping system of farmland was made. From the experiment results of 4～6 years in three experimental spots, it is exposed that there was much more potential of grain production in this area, and the self-supply of grain food is able come true; the main constraint of restricting the realization of potential and the self-supply of grain food is soil fertility shortage. In order to raising the fertility inputting quantity of chemical fertilizer has to be increased at present. From long run turning farmland back, reforming cropping system, planting grasses and developing animal husbandry and combining agriculture with animal husbandry should be put into practice.
