为了探讨“化学杀雄”杂交水稻赣化二号二代利用价值,我所去年种植了1.83亩,由于用种量偏少,栽插过稀,管理不善,产量较低,亩产只有560斤,比同类型田的油优二号亩产少75斤,与常规晚稻品种不相上下。现将结果整理如下: 一、生育期的分离赣化二号二代栽培在生育期上表现了一定的分离。田间观察结果,最早与最迟抽穗的(不包括过冬青)相差27天,从播种到始穗相差37天,全生育期最短为115天,最长为145天,相差30天。(表1)
In order to explore the utilization value of chemical kill male hybrid rice, the second generation of Ganhua No.2, I planted 1.83 mu last year. As a result of less planting, too thin planting, poor management and low yield, only 560 kg per mu , Less than 75 pounds less than the same type of oil Youyou No. 2, comparable with the conventional late rice varieties. The results are now organized as follows: First, the separation of the growth period Jiangxi second generation of cultivation in the growth period showed a certain degree of separation. Field observations, the earliest and latest heading (excluding holly) a difference of 27 days from sowing to the beginning of a panicle difference of 37 days, the shortest for the whole growth period of 115 days, the longest of 145 days, a difference of 30 days.
