| 摘 要： | 以晚籼三系杂交新组合天丰优134为材料,研究了不同播种量和秧龄期对秧苗素质、生育进程、稻米品质及产量的影响.结果表明,该品种适宜的秧龄期为30 d,最长不宜超过35 d,作二季晚稻常规栽培适宜移栽叶龄为7叶左右,9叶期为其早穗的临界叶龄:在适宜的秧龄条件下,播种量为225.0 kg·hm~(-2)左右:该品种收获指数高、千粒重高、适应性强,其高产措施主要是稀播壮秧、增加分蘖、提高成穗率.

| Abstract: | With the new three-line late indica hybrid rice combination Tianfengyou 134 as material, the effects of different seeding rate and seedling age on the seedling quality, growing process, rice quality and final output were studied. The suit-able seeding rate, appropriate seedling age and key measures for high yield cultivation of the rice variety were summarized. The results indicated that the best seedling age was 30d and not longer than 35d; the suitable leaf age of transplanting was around 7 for late-season regular cultivation; the phase with 9 leaves was its premature heading's critical leaf age; the seed-ing rate could reach 225.0kg/hm~2 under suitable seedling age condition; this variety had a high harvest index, large thou-sand kernel weight and strong adaptability; scattered seeding for healthy seedlings and increasing tillers to promote percent-age of earbearing tillers were key measures for high yield cultivation. |
