不同株型水稻品种的产量差异,不仅决定于它们的形态特征,还决定于它们的光合生理特性、各器官生长的相关关系等。深入研究与掌握不同株型水稻品种影响光合产量的因子,对于品种选育及高产栽培都具有重要意义。 一、材料与方法 本试验中以高秆披散型、中秆直立型及矮秆直立型三种株型的水稻各3个品种为试验材料。4月19日于大田播种育秧。一部分于6月11日在大田进行单株栽插,株行距5×6寸;另一部分盆栽,每盆3株。管理与当地一般丰产田相同。
The yield differences of different plant type rice varieties depend not only on their morphological characteristics but also on their photosynthetic physiological characteristics and the relationship between the growth of various organs. In-depth study and master of different types of rice varieties of photosynthetic yield factors, for variety breeding and high-yield cultivation are of great significance. First, materials and methods In this experiment, three varieties of high-stalk Phi-type, vertical stalks and dwarf upright three types of rice were used as experimental materials. April 19 sowing seedlings in the field. A part of transplanting was carried out in Daejeon on June 11, with spacing of 5 × 6 inches; the other part was potted with 3 plants per pot. Management and the same local general high yield fields.
