摘要: 以杂交稻协优527为材料,研究了在强化栽培条件下适宜的移栽叶龄和栽植密度。结果表明不同移栽叶龄(2~5叶龄)对其产量的影响很小,在强化栽培应用中,可以采用4~5叶龄的带蘖秧苗移栽;在本试验范围内,强化栽培的适宜栽培密度为9万穴/hm2~13.5万穴/hm2,此时,后期光合产物积累多,穗、粒结构合理,产量可达最高。

关键词: 水稻强化栽培, 秧龄, 栽植密度, 产量

Abstract: The seedling-age and planting density in System of Rice Intensification (SRI) were studied with Xieyou 527, a hybrid rice cultivar. The result indicates that no effect of seedling-ages on grain yield is found. In production practice of SRI, the selection of seedling-ages is 2 to 5 leaf-age. The suitable planting density is 9×104 plant/hm2 to 13.5×104 plant/hm2 and the grain yield is the highest.

Key words: System of Rice Intensification (SRI), seedling-age, planting density, grain yield
