摘要
【目的】枣棉间套作条件下,红枣供水状况与单作红枣具有一定的差异性,研究红枣主要应用的3种灌溉模式和不同灌水量对红枣的影响;【方法】通过设置红枣3因素2水平试验设计,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比较均为滴灌>微喷>沟灌,并且红枣单株产量滴灌>沟灌>微喷,差异达到显著水平;不同灌水量水平下,红枣各项调查指标均表现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产量。【结论】滴灌、微喷和沟灌增加灌水量都能显著促进红枣的生长和提高红枣产量,3种灌溉模式对红枣的影响表现为滴灌>沟灌>微喷。
【Objective】There are certain differences in jujube water quantity in irrigation between jujube- cotton intercropping and monoculture,just for these reasons,our project aims to make sure the effect of the three irrigation modes and different jujube water quantities on the growth of jujube.【Method】The field experiment with three factors and two levels were designed for the study in order to research the effect of all treatments with the yield,quality,bearing branchlets,flower,fruit diameter of jujube.【Result】In different irrigation patterns,the length of bearing branchlets was drip irrigation > furrow irrigation > micro spray,and the comparison of the number of bearing branchlet,the bud number,the flower number and the fruit diameter was drip irrigation > micro spray > furrow irrigation,and the result of comparison of the yield was drip irrigation > furrow irrigation > micro spray. The differences reached significantly high level. With different irrigation quantities,the high irrigation water quantity treatment was higher than the low irrigation quantity treatment in every survey index.【Conclusion】The analysis indicated that drip irrigation,micro spray and furrow irrigation and the increased irrigation water quantity can significantly promote the growth and the yield of jujube; The result showed that the three kinds of irrigation patterns affect the jujube: drip irrigation > furrow irrigation > micro spray.
