机插水稻合理基本苗的研究,是水稻高产群体质量栽培技术的一个重要内容。本试验通过不同播量与栽插密度和取秧量形成不同数量的大田基本苗,而探索不同规模的群体质量及其与产量间的关系,以明确机插稻适宜的基本苗数量,为建立机插稻高产栽培理论及技术体系提供依据。1材料与方法1.1供试品种武进稻麦育种场选育的水稻新品系5356(武粳15),主茎17.4,6个伸长节间,全生育期156d。1.2试验设计由三因素组成不同基本苗。即秧盘播量:设3个水平,120g/盘、150g/盘、180g/盘;取秧量:设2个水
The research on reasonable basic seedlings of rice-inserted rice is an important part of the high-yielding population quality cultivation techniques. In this experiment, different numbers of planting sowing density and seedling yield were used to form different numbers of basic seedlings in the field. The quality of different groups and their relationship with yield were explored to determine the suitable number of basic seedlings for rice planting. Machine-made rice high yield cultivation theory and technical system to provide the basis. MATERIALS AND METHODS A. A new rice line 5356 (Wujing 15) with 17.4 main stems and 6 elongate internodes bred in the Wujin rice and wheat breeding field was grown for 156 days. 1.2 The experimental design consists of three elements of different basic seedlings. The amount of seeding pantry: set 3 levels, 120g / plate, 150g / plate, 180g / plate; take seedling volume: set up two water
