【摘要】 [目的]为了解枣棉间套作条件下红枣供水状况与单作红枣间的差异性,研究红枣种植中主要应用的3种灌溉模式和不同红枣灌水量对红枣的影响。[方法]通过设计3因素2水平试验,研究不同处理对红枣枣吊长度、枣吊数量、开花数量、果径变化以及产量品质的影响。[结果]不同灌溉模式下,枣吊长度滴灌>沟灌>微喷,单个枣股枣吊数量和单个枣吊蕾、花数以及横纵径之积均为滴灌>微喷>沟灌,且红枣单株产量滴灌>沟灌>微喷,差异达显著水平;不同灌水量水平下,红枣各项调查指标均表现为高灌溉量处理优于低灌量处理,枣单株产量高灌量显著大于低灌量。[结论]该研究表明,滴灌、微喷和沟灌增加灌水量都能显著促进红枣的生长和产量提高,3种灌溉模式对红枣的影响表现为滴灌>沟灌>微喷。更多还原

【Abstract】 [Objective] The aim was to explore the differences of jujube growth by intercropping with cotton and mono-cropping and to research effects of three irrigation models and quantity on jujube. [Method] The field experiment with three factors and two levels were applied for the study in order to research the effect of all treatments with the yield, quality, bearing branch, flower, fruit diameter of jujube. [Result]With different irrigation patterns, the result of comparing the length of bearing branch was drip irrigation > furrow irrigation > micro spray, and the result of comparing the number of bearing branch, the bud number, the flower number, fruit diameter was the same, as follows: drip irrigation > microjet irrigation > furrow irrigation; the result of comparing the yield was drip irrigation > furrow irrigation > microjet irrigation with significant differences. With different irrigation quantities, high irrigation water quantity treatment was proved higher than low irrigation quantity treatment in every survey index. [Conclusion] The analysis indicates that drip irrigation, microjet irrigation and furrow irrigation increased the irrigation water quantity can significantly promote the growth and the yield of jujube and the effects of the three kinds of irrigation patterns are drip irrigation > furrow irrigation > microjet irrigation.更多还原
