北方缺水地区半旱地农业有限补灌模式探讨

李英能

《中国工程科学》 2012年第14卷第3期页码 41-45

摘要：

以降水利用和灌溉程度为依据，对半旱地农业进行了研究，着重讨论了与半旱地农业涵义有关的问题，论述了在北方缺水地区发展半旱地农业的意义，给出了半旱地农业有限补灌技术模式。针对北方缺水地区的特点，提出了不同类型区半旱地农业有限补灌发展模式，并探讨了北方缺水地区半旱地农业发展有限补灌的策略。

Fighting for the poverty: a case study for human migration in the context of sustainable dryland farming

Yongqing MA, Jie CHEN, Shuqi DONG, Lun SHAN

《农业科学与工程前沿（英文）》 2014年第1卷第1期页码 62-68 doi: 10.15302/J-FASE-2014027

摘要： The Southern Ningxia Hilly Area is one of the most impoverished areas of Ningxia Hui Autonomous Region (a province) of China due to an economy that mainly relies on agriculture, which is affected by droughts in two out of every three years. Government programs have attempted to develop an increased and sustainable level of scientifically based agricultural production while restoring the environment. However, since the population exceeds the capacity of the land to adequately support it, a program is underway to move 350000 people to more suitable locations. This paper outlines the past improvements to the Southern Ningxia Hilly Area and considers future development in the context of migration for ecological reasons.

黄淮海地区农业节水对策及实施半旱地农业可行性研究

山仑,吴普特 , 康绍忠, 冯浩 , 张岁岐

《中国工程科学》 2011年第13卷第4期页码 37-42

摘要：

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。

LIGHT INTERCEPTION AND USE EFFICIENCY DIFFER WITH MAIZE PLANT DENSITY IN MAIZE-PEANUT INTERCROPPING

《农业科学与工程前沿（英文）》 2021年第8卷第3期页码 432-446 doi: 10.15302/J-FASE-2021403

摘要：

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.

甘肃省旱地农业技术创新与实践

郭贤仕,柳燕兰,候慧芝,郭天文

《中国工程科学》 2012年第14卷第3期页码 65-69

摘要：

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。
