【摘要】 试验通过优质早籼嘉早935和中质早籼浙733应用水稻节水高效栽培和常规栽培的比较,研究节水高效栽培技术对直播水稻生育前中期生长及其生理特性的影响。研究表明:应用水稻节水高效栽培技术,田间无效分蘖期缩短,最高苗峰降低,根系活力增强,叶片叶绿素含量提高,细胞内的CO₂浓度和净光合速率提高,个体生长明显改善,为提高分蘖成穗率、争取大穗高产优质奠定了基础。更多还原

【Abstract】 It’s through the test to compare the economize-on-water planting and normal planting of the earlier indica rice Jiazao 935 and the media earlier indica rice Zhe 733 to study the effect on direct seeding rice growth and its physiological characteristics. The study shows that applied with economize-on-water planting technique, it shortens the ineffective tillering stage, lowers the highest seedling peak, increases the root system energy, increases the amount of chloroghyll and so on and lay the foundation to got high quality rice.更多还原
