在水稻杂交制种中,花期调节是关键的技术措施。割叶调花对延迟抽穗期具有一定的作用,但是,对水稻也产生植伤的副作用。如何掌握割叶调花技术,达到趋利避害,是本试验的研究目的。一、试验材料与方法试验地点在海康县龙门区。试验组合是“珍汕97A”ד明恢63号”。父本比母本抽穗早7—8天,割父本叶以调节花期。设9个处理,即分别在幼穗分化1期、3期、5期进
In hybrid rice production, florescence regulation is the key technical measure. Leaf cut flowers have some effect on the delayed heading stage, but also have the side effect of planting rice. How to master the cutting leaf transfer flower technology, to achieve the benefits and avoidance, is the purpose of this study. First, the test materials and methods Test sites in Longmen District, Haikang. The test combination is “Zhenshan 97A” × “Ming Hui 63”. Parents 7-8 days earlier than the parent heading, cut the father to regulate the flowering of the leaves. Set nine treatments, namely in panicle differentiation stage 1, stage 3, stage 5
