| 摘 要： | 旨在获得生育期在120天左右的耐盐碱早熟水稻品种的优质、高产栽培技术，进行优质高效水直播栽培技术研究。以早熟粳稻水稻品种‘吉宏6号’为试验材料，利用3‰~6‰中度盐碱地大田耕平地、灌排水、浸种播种、病虫草害防治、施肥最佳模式进行交叉试验。经过3年的试验研究，得出耐盐碱早熟水稻品种优质高效水直播技术规程。该规程规定了滨海盐碱地水稻优质高效水直播栽培技术，规定了生育期120天的优质水稻种质质量及浸种技术、春季深翻耕平地技术要求，规定了播种期、出苗期、分蘖期、长穗期、结实期对灌排水、地下害虫防治、草害防治、病害防治、施肥管理的技术规程，规定了蜡熟末期、晚熟初期的适时收获标准，规定了水稻脱粒、运输及仓储要求。该技术规程，无需泡田，节约用水量达50%；晚播将灌浆期控制在9月中旬，有效地防止鸟害；适时收获，能显著提高水稻的食味品质。

| Abstract: | The study aims to obtain high-quality and high-yield cultivation techniques of saline-alkali tolerant and early-maturing rice varieties with the growth period about 120 days under water direct seeding cultivation. Taking early-maturing japonica rice variety ‘Jihong No.6’ as the experimental material, the cross test was conducted with irrigation and drainage, seed soaking and sowing, pest and weed control and the best mode of fertilization in 3‰-6‰ moderate saline-alkali soil. After three years of experimental research, the technical regulations of high-quality and high-efficiency water direct seeding of early-maturing rice varieties with saline-alkali tolerance were obtained. The regulation stipulated (1) the high-quality and high-efficiency water direct seeding cultivation technology in coastal saline-alkali land; (2) the quality of high-quality rice germplasm with 120 days of growth period, and the technical requirements of soaking seed and deep ploughing in spring; (3) the technical regulations of irrigation and drainage, underground pest control, grass pest control, disease control and fertilization management in sowing, emergence, tillering, long panicle and seed setting stages; (4) the standard of timely harvest at the end of wax ripening and the early stage of late ripening; and (5) the requirements of threshing, transportation and storage of rice. According to the technical specification, there is no need to soak the field, and the water consumption could be saved up to 50%. Late sowing could control the grain filling period in mid-September and effectively prevent bird damage. Timely harvest can significantly improve the eating quality of rice. |
