摘要:

南粳46高产优质,培育15~20 d的秧龄、叶龄 3.5 叶、根盘结牢固、单株白根量10 条以上的壮秧,是其机插高产的基础;标准的移栽深度、株行距、单位面积基本苗数,是精确定量栽培的关键技术指标。根据产量目标,结合配方施肥原理,做好机插全生育期的肥水运筹,可以有效提高南粳46的有效分蘖率,促进籽粒灌浆结实,有效穗数达到21.7万/667 m2,结实率达89.4%,从而实现600 kg/667 m2左右的产量。

Abstract:

Nangeng 46 is a high yield and good quality rice variety. Cultivating 15~20 d seedling age, 3.5 leaf age, the roots firmly and above 10 roots per plant are the basises for high yield cultivation of machine transplanted rice. The standard of transplanting depth, transplanting spacing, basic seedling number per hectare are the key technical indicators of precise quantitative cultivation. According to the production target, combining with the principle of formula fertilization and doing a good job on fertilizer and water application in the whole growth period, can effectively improve the effective tillering rates of Nangeng 46, the effective panicles can reach 2.17×105/667 m2, the seed setting rate of 89.4%, and achieve the yield of 600 kg/667 m2.

Key words: Nangeng 46, substrate, machine transplanted rice
