通过系统调研,从挖掘各类农业水资源潜力入手,分析总结了黄淮海地区农业节水的成效、经验与存在的问题,认为在充分利用降水基础上实施补充少量灌溉水的半旱地农业是解决该区域水资源严重短缺,同时实现农业生产可持续增长的一条重要出路。旱地农业、灌溉农业和半旱地农业并存将成为未来农业用水的新格局,按此对策实施,预期到2020年,该地区农田灌溉用水量可减少30 %以上,并率先实现农业用水系统的现代化。

Intercropping increases crop yields by optimizing light interception and/or use efficiency. Although intercropping combinations and metrics have been reported, the effects of plant density on light use are not well documented. Here, we examined the light interception and use efficiency in maize-peanut intercropping with different maize plant densities in two row configurations in semiarid dryland agriculture over a two-year period. The field experiment comprised four cropping systems, i.e. monocropped maize, monocropped peanut, maize-peanut intercropping with two rows of maize and four rows of peanut, intercropping with four rows of maize and four rows of peanut, and three maize plant densities (3.0, 4.5 and 6.0 plants m−1 row) in both monocropped and intercropping maize. The mean total light interception in intercropping across years and densities was 779 MJ·m−2, 5.5% higher than in monocropped peanut (737 MJ·m−2) and 7.6% lower than in monocropped maize (843 MJ·m−2). Increasing maize density increased light interception in monocropped maize but did not affect the total light interception in the intercrops. Across years the LUE of maize was 2.9 g·MJ−1 and was not affected by cropping system but increased with maize plant density. The LUE of peanut was enhanced in intercropping, especially in a wetter year. The yield advantage of maize-peanut intercropping resulted mainly from the LUE of peanut. These results will help to optimize agronomic management and system design and provide evidence for system level light use efficiency in intercropping.

甘肃省地理跨度大,气候类型多种多样,旱地农业类型齐全,在长期的生产实践和科研活动中,把有效的传统抗旱办法与农田微集雨保墒工程、旱农耕作栽培技术、农业机械有机结合,创造了很多有区域特色的旱地农业技术。本文对甘肃省传统的砂田种植技术和旱地地膜小麦穴播技术、集雨农业技术体系进行简单回顾,对现阶段正在应用的主体创新旱农技术——全膜双垄沟播玉米、膜上覆土小麦种植技术体系的基本特点、抗旱增产机理及应用情况进行较详细的介绍。
