提高半干旱地区旱地农田生产力的现实途径和未来策略
- Title:
- Realist Approches and Future Strategy for Increasing Productivity in Dry Farmland, Semiarid Areas
- 摘要:
- 本文介绍了半干旱地区农业生态环境特点及所面临的问题,评述了提高旱地农田生产力的若干现实途径,并就进一步如何深化研究提出了建议.作者认为,科学地运用已有耕作栽培措施便可以实现黄土高原地区农田粮食产量增加一倍的目标;而实行充分利用环境水和最大限度节约作物本身用水相结合的技术策略是未来旱地农业得以持续增产的关键.为此,必须加强综合研究.
- Abstract:
- In this paper,the characteristics of agroecological envirnment and some problems faced in the semiarid areas were discussed.In the meantime,some present approches to increasing productivity in the dryland farming were reviewed.The suggestions for deepening research aspects in the future were proposed too.It was considered that,in Loess plateau,the objective to increase 2 times of grain output can be realized by using the current measures of tillage and cultivation.For increasing yield sustainedly in the dryland agriculture,the key is to take such technical strategy as follows:fully utilize envirnmental water,reduce the water consumption of crops as far as possible,and combine the two etireIy.So that,the comprehensive studies should be strenthened in the future.
