fall irrigation meaning in English
秋季灌溉
Examples
- ( 2 ) aiming at the bigger irrigation quota of fall irrigation system and the complicacy of the salt movement in soil , the paper applies reservoir leaching model bring forwarded by w . h . van der molen to hetao irrigation district located in aridity area , and establishes salt leaching simulational model under the fall irrigation system . through calculating , the feasible fall irrigation quota is 100 - 120m2 / 667m2 in light salinization soil , and the feasible fall irrigation quota is 120 - 150 m2 / 667m2 in mild salinization soil . the model is reasonable and exact , and it can be researched deep
( 2 )针对在秋浇灌溉制度中秋浇定额较大，土壤中盐分运移规律复杂的特点，利用w ? h ? vandermolen提出的水库冲洗模型，建立了地处干旱地区的河套灌区区域内的秋浇制度盐分淋洗模拟模型。经计算在轻度盐渍化土壤中秋浇的灌溉定额以100 120m ~ 3 667m ~ 2为宜；中度盐渍化土壤秋浇的灌溉定额以120 150m ~ 3 667m ~ 2为宜，模型合理可靠，准确可行，可进一步向纵深方向进行研究。 - Facing to the reduction of the water diversion from the yellow river for hetao irrigation district inner mongolia autonomy , and giving attentin to agriculture production and improvement of salinization , this paper researches optimization model of district water - saving irrigation water management . the paper also quests for the optimization model of crop irrigation system and the optimization irrigation strategy aiming at the short of water for agriculture . in order to save water and use water high efficiently , this paper researches the change regulation of irrigation system of spring - wheat that is the important crop in the irrigation districted establishes the multidimensional dynamic model of irrigation rules of spring - wheat . lt also makes the simulation model of salt leaching of fall irrigation rules during non - growing period , and sorts the elements influencing water - saving of irrigation system
在内蒙古河套灌区的引黄水量减少又要兼顾灌区的农业生产和土壤盐渍化向良性发展的形势之下，本文针对灌区内区域灌溉水管理的现状，对灌区内区域节水灌溉水管理优化模型进行了研究。研究针对农业水资源短缺的现状，在节水灌溉条件下，对作物的灌溉制度进行优化模型探索，寻求最优灌溉策略。全文围绕节水与高效用水，综合应用了系统分析、灌溉排水及节水灌溉的原理和知识，研究了灌域内主要作物春小麦的灌溉制度的变化规律，建立了春小麦灌水制度的多维动态优化模型；建立了非生育期的秋浇制度的盐分淋洗模拟模型；对节水灌溉水管理的影响因素的重要性进行了排序研究。
