【摘要】 合理利用水资源已成为影响立体种植这一高产高效传统栽培技术持续发展的重要因素之一。本文在总结立体种植历史和现状的基础上,提出了立体种植高效用水中存在的问题,并对其中一些关键性问题进行了初步研究。在考虑冠层、根系分布和土壤水分分布等特点的基础上,以单作种植研究成果为基础,提出了立体种植条件下的作物需水量新的计算模式,产量与水分关系的水分效益函数表达式,相应的需水量计算和效益计算修正系数概念,以及制定立体种植优化灌溉制度的方法。更多还原

【Abstract】 Reasonable use of water resources has become one of the important factors affacting the sustainable development of intercropping production which is a traditional cultivation technology with high yield and efficiency. Based on the history and present status of the intercropping production, the problems of efficient water use in intercropping are put forward, among which the key problems are preliminarily studied. Taking into consideration the characteristics such as the distribution of corona and root system, the distribution of soil moisture content, based on the research results of single cropping, the new calculation model for crop water demand, the function formula of water efficiency relationship between yield and water, the calculation method of water demand and the concept of modifying factor for efficiency calculation are presented. The method for formulating optimized irrigation scheduling of the intercropping production is developed.更多还原
