| 摘要: |
| 【目的】探明宁夏银北地区不同耐盐碱水稻品种对灌水定额响应特征。【方法】以宁夏银北地区大面积推广的2个耐盐碱水稻品种：宁粳56号（NJ56）和吉粳105号（JJ105）为研究对象，设置4个灌水定额分配方式（W1、W2、W3、W4处理），研究灌水定额分配方式对宁夏银北地区耐盐碱水稻生长、产量及品质的影响，并进行综合评价得出最佳灌水定额和耐盐高产水稻品种。【结果】吉粳150号水稻W1处理下的垩白粒率和垩白度最高，分别达到68.67%和19.30%，W2处理下水稻出苗率较高，达到84.47%，W3处理下精米率、蛋白质量、胶稠度最高，分别达到81.76%、9.40%、9.13。宁粳56号水稻W1处理下水稻分蘖成穗率、实际产量、灌水利用效率、含水率、直链淀粉量均最高，分别达到75.67%、10388.78 kg/hm2、101.85%、10.50%、20.07%，W3处理下千粒质量最高，达到24.83 g，W4处理水稻穗长和单穗粒质量最高，分别达到21.35 cm和2.81 g，宁粳56号水稻和吉粳105号水稻的W4处理碱消值同时达到7。【结论】最佳灌水量和品种为W4（出苗前期2100 m3/hm2、苗期1500 m3/hm2、分蘖期2100 m3/hm2、拔节期1350 m3/hm2、抽穗期1500 m3/hm2、灌浆期1650 m3/hm2）和宁粳56号水稻，是宁夏盐碱地治理节水抑盐调控效果较好的灌溉技术。 |

| Abstract: |
| 【Objective】 In order to explore the response characteristics of different saline-alkali tolerant rice varieties to different irrigation quotas in the northern part of Yinchuan in Ningxia Hui Autonomous Region. 【Method】 Ningjing 56 (NJ56) and Jijing 105 (JJ105), two saline-alkali tolerant rice varieties popularized in the northern part of Yinchuan in Ningxia Hui Autonomous Region., were set as the research objects, and four different irrigation quota allocation methods W1, W2, W3, W4 treatment to study the effects of different irrigation quotas on the growth, yield and quality of saline-alkali tolerant rice in the northern part of Yinchuan in Ningxia Hui Autonomous Region. and the optimal irrigation quotas and salt-tolerant and high-yield rice varieties were comprehensively evaluated. 【Result】 The results showed that the chalky grain rate and chalkiness were the highest under W1 treatment (68.67% and 19.30%, respectively), the seedling emergence rate was higher (84.47%) under W2 treatment, and the highest milling rate, protein content and gel consistency were the highest under W3 treatment, reaching 81.76%, 9.40%, 9.13, respectively. The tillering and panicle formation rate, actual yield, irrigation use efficiency, water and amylose of rice under W1 treatment of Ningjing 56 rice were the highest, reaching 75.67%, 10388.78 kg/hm2, 101.85%, 10.50%, 20.07%, respectively, the 1000-grain weight was the highest under W3 treatment. When the rice spike length and grain weight per spike were the highest in the W4 treatment of 24.83 g, reaching 21.35 cm and 2.81 g, respectively, the alkali elimination value of the W4 treatment of Ningjing 56 rice and Jijing 105 rice reached 7 at the same time. 【Conclusion】 There were significant differences between different irrigation quotas and saline-alkali tolerant rice varieties, and the optimal irrigation amount and varieties were W4 (2100 m3/hm2 at early emergence, 1500 m3/hm2 at seedling stage, 2100 m3/hm2 at tillering stage, 1350 m3/hm2 at jointing stage, 1500 m3/hm2 at heading stage, 1650 m3/hm2 at grain filling stage) and Ningjing 56 rice, which provide a reference for the irrigation technology of water saving and salt suppression regulation in saline-alkali land management in Ningxia Hui Autonomous Region. |
