摘要
为明确金早645适宜机插密度,在浙江省兰溪市开展了 3个不同机插密度试验.结果表明,机插密度30 cm × 14 cm(即栽插23.85万丛/hm2)处理表现有效穗数较多、穗型较大、结实率高、千粒重高、产量结构合理、产量最高.综合试验结果,金早645在兰溪市的机插密度以30 cm × 14 cm为宜,表现群体与个体生产协调,有利于取得较高产量.
Abstract
3 mechine-transplanting density test was conducted to ascertain optimal density for Jinzao 645.Results showed that treatment of 30 cm × 14 cm(23.85 × 104 hill per hm2)had advantages of more efffective panicles and larger panicle,higher seed setting rate and 1000-grain weight,proper yield components structure and the highest yield.Thus,the suitable transplanting density is 30 cm × 14 cm in Lanxi can promote coordination of population and individual peoduction to achieve high yield.
