黑龙江长粒水稻品种,哈417水稻积温是多少

以龙稻18为例,生长周期为135-140天左右,需≥10°C的活动积

温为2480-2550°C,株高98cm左右,主茎上长有12.5片叶,穗长22cm

左右,每个穗上有140颗穗粒,千粒重为27g,2011-2012年间,试

验区亩产量平均为585.5kg,2013年,试验区亩产量平均为566.04kg。

一、黑龙江长粒水稻品种

1、垦盈1号水稻介绍

(1)植株外形:株高88cm左右,主茎上长有12-13片叶。

(2)穗粒特征:穗长23cm左右,每个穗上有150颗穗粒,千

粒重为31g。

(3)米粒:米粒优质,长宽比为2.1:1。

(4)产量:每亩地平均产量为600kg,高产情况下亩产量可以

达到667kg。

(5)抗性:适应能力强,抗倒伏能力极强,耐寒性强,抗病能

力强。

(6)其他:生长周期为135天,需≥10°C活动积温要求在2500°C。

2、龙稻18号水稻介绍

(1)植株外形:株高98cm左右,主茎上长有12.5片叶。

(2)穗粒特征:穗长22cm左右,每个穗上有140颗穗粒,千

粒重为27g。

(3)米粒:出糙率81.3%,整精米率70.5-70.6%,垩白粒米率

2-7%,垩白度0.2-0.9%,直链淀粉含量17.12-17.23%,胶稠度

80.5-81.0mm。

(4)产量:2011-2012年间,试验区亩产量平均为585.5kg,2013

年,试验区亩产量平均为566.04kg。

(5)抗性:三年抗病接种鉴定结果为叶瘟0-1级,穗颈瘟0级。

三年耐冷性鉴定结果为处理空壳率1.81-6.11%。

(6)其他:生长周期为135-140天左右,需≥10°C活动积温

2480-2550°C。

二、哈417水稻积温是多少

1、哈417审定后称之为龙稻21,需≥10°C活动积温2650°C左右。

2、活动积温:指的是大于等于10°C的日平均气温相加,最终得

到的气温总和,叫做活动积温。比如某3天的日平均气温分别为13°C,

14°C,15°C,则活动积温为42°C。
