摘要:

【目的】研究不同灌溉量对水稻农艺性状、抗倒伏特性及产量形成的影响,探索较适宜的水稻高产稳产绿色栽培水分管理方案,为水稻可持续生产提供理论依据。【方法】以五优稻4号(WYD4)和吉农大667(JND667)为试验材料,进行6个不同灌溉量处理:W1(12 000 m3·hm-2),W2(10 500 m3·hm-2),W3(9 000 m3·hm-2),W4(7 500 m3·hm-2),W5(6 000 m3·hm-2)和W6(天然雨养),通过研究不同灌溉量对水稻株型、抗倒伏能力、光合特性、干物质积累和产量的影响,明确不同灌溉量对其调控效应及机制。【结果】适当地减少灌溉量,提高了水稻最终茎蘖数、茎蘖成穗率、上三叶叶长、叶面积指数,降低了上三叶叶宽、叶基角和株高。W4处理能够优化水稻株型,促进植株生长,形成良好的群体结构。随着灌溉量的减少,水稻基部第二节间茎秆长度降低,节间充实度、抗折力、倒伏指数和茎鞘中木质素、纤维素含量都呈先上升后下降的趋势。适宜的灌溉量有利于水稻茎秆抗倒伏能力的提高;在提高水分利用效率的同时,提高了水稻剑叶的光合性能、茎鞘干物质的积累和运输能力,有利于产量的形成。与W1处理相比,W4处理节约了37.50%的灌溉用水量,产量显著提高了9.07%—12.47%。【结论】在W4(7 500 m3·hm-2)处理下,水稻相较于其他处理有更好的株型、抗倒伏能力、光合性能、干物质积累,在水分利用效率较高的同时拥有了最高的产量,可作为本地区较为适宜的灌溉量。

Abstract:

【Objective】To study the effects of different irrigation volumes on the agronomic traits, lodging resistance and yield formation of rice, and to explore a more suitable water management plan for high-yield and stable-yield green cultivation of rice, and to provide a theoretical basis for sustainable rice production.【Method】Using WYD4 and JND667 as experimental materials, six different irrigation volume treatments were carried out: W1 (12 000 m3·hm-2), W2 (10 500 m3·hm-2), W3 (9 000 m3·hm-2), W4 (7 500 m3·hm-2), W5 (6 000 m3·hm-2) and W6 (natural rainfall). By studying the effects of different irrigation volumes on the plant architecture, resistance to lodging, photosynthetic characteristics, dry matter accumulation and yield of rice, the regulatory effects and mechanisms of different irrigation volumes on these aspects were clarified.【Result】Reducing irrigation properly increased the final tiller number, the percentage of productive tillers, leaf length of the top three leaves, and leaf area index of rice, while reducing the leaf width and leaf base angle of the top three leaves, as well as plant height. The W4 treatment can optimize the plant morphology of rice, promote plant growth, and form a good population structure. With the decrease in irrigation volume, the length of the second internode at the base of rice decreased, and the internode plumpness, breaking resistance, lodging index, and the contents of lignin and cellulose in the stem and sheath first increased and then decreased. Proper irrigation was beneficial for improving the lodging resistance of rice stems. Appropriate irrigation volume not only improves water use efficiency but also enhances the photosynthetic performance of the flag leaves of rice, the accumulation and transportation capacity of dry matter in the stem and sheath, which is beneficial to yield formation. Compared with the W1 treatment, the W4 treatment saved 37.50% of the irrigation water consumption, and the yield significantly increased by 9.07%-12.47%.【Conclusion】Under the W4 (7 500 m3·hm-2) treatment, rice has better plant morphology, lodging resistance, photosynthetic performance, and dry matter accumulation compared with other treatments. Therefore, it has the highest yield while having a high water use efficiency and can be used as a more suitable irrigation volume in this region.
