微喷弥雾调控灌水技术对葡萄生理和产量的影响研究

旨在确定较优的微喷弥雾调控灌水技术方式。分析在不同微喷弥雾调控灌水技术方式下对葡萄枝条数、叶片数、节间长等生理指数和产量指标的影响。在不同弥雾微环境调控技术处理下，葡萄的各项生理指标均表现出一定的规律性，由于叶面积指数与叶片数、枝条数及单叶面积等有关，不同处理中WP4、WP5的叶面积指数最大，WP2和WP3居中，而对照CK处理最小。在产量的表现上，对照处理的产量为29275.5 kg/hm2，仅高于WP5（28591.5 kg/hm2），WP3产量最高，为38313 kg/hm2，相比对照高出30.9%，其后是WP1、WP2和WP4，分别为33906 kg/hm2、33361.5 kg/hm2和32124 kg/hm2。葡萄微喷弥雾调控灌水技术在灌溉定额9150 m3/hm2，每天喷水1次，每次1~2 h，每次喷水量在105~120 m3/hm2时可以获得较高的葡萄产量。

Micro-sprinkling Spraying Irrigation Technique:Effect on Grape Physiology and Yield

The aim was to optimize micro-sprinkling spraying irrigation technique. The effects of different irrigation techniques on the physiology and yield indexes including grape branch number, leaf number and internode length were studied. All of the physiology indexes showed certain regularity of different irrigation techniques. The leaf area index presented a correlation with the branch number, leaf number and leaf area. Among different treatments, WP4 and WP5 had the maximum leaf area index, followed by WP2 and WP3, and the control group had the minimum value. In the aspect of yield, the yield of control group was 29275.5 kg/hm2, which was only higher than that of WP5 (28591.5 kg/hm2). WP3 had the maximum yield value of 38313 kg/hm2, 30.9% higher than that of control group, followed by WP1, WP2 and WP4, which was 33906 kg/hm2, 33361.5 kg/hm2 and 32124 kg/hm2 respectively. The grape had higher yield under the micro- sprinkling spraying irrigation technique with the irrigation quota of 9150 m3/hm2, once per day for 1-2 hours, and the water spray quantity was 105-120 m3/hm2 each time.
