1989年湖南省种植杂交早稻481.42万亩,比1988年扩大94.12万亩,总产21.04亿公斤,平均亩产437公斤。 在连续遭受几次阴雨寡照不利气候影响的条件下,杂交早稻比常规早稻较好地经受了考验,显示出明显的增产优势。据省、地两级联办的14个基点验收924亩杂交稻,平均亩产511. 6公斤,比
In 1989, 481.42 million mu of early hybrid rice was planted in Hunan Province, an increase of 94.12 million mu from 1988, with a total output of 2.104 billion kg and an average yield of 437 kg per mu. Under several adverse weather conditions, the hybrid early rice was better tested than the conventional early rice and showed obvious yield increase. According to provincial and prefectural liaison offices of 14 basis points acceptance of 924 acres of hybrid rice, the average yield 511. 6 kg, than

马家柚(Citrus grandis Swingle)是原产江西省广丰县的优良柚品种。其果肉细嫩,色泽浅红,味道清香,风味独特,是广丰县的主栽柑橘品种,支撑着当地的柑橘产业。虽然,套袋是我国苹果等果树广泛采用的技术措施,但是,在柑橘生产却没有那么普遍。而且,对其作用机制并未研究透彻。栽培过程中发现马家柚套袋后不仅果实表面更加平滑,果肉颜色也加深了。基于此,本课题以套袋和不套袋不同发育时期的马家柚为
