野香A高产制种技术探讨

Study on seed production technology of high yield variety Yexiang A

野香A杂交稻高产、优质和稻米卖相好,种植面积在全国水稻面积逐年减少的背景下逆势而上,制种面积逐年扩大。文章分析野香A特征特性,提出野香A高产制种关键技术,主要有:合理安排安全抽穗杨花期,突出抓好强大父本的培育,平衡施肥,搭建母本丰产苗架,矮化栽培,割叶制种,突出抓好稻曲病、细条病防治等,旨为从事野香A制种的广大农户和技术人员参考。

The hybrid rice variety Yexiang A has the follows advantages:high yield,good quality and good sale of rice.The planting area is rising against the background of decreasing rice area year by year,and the area of seed production is expanding year by year.In this paper,the characteristics of variety Yexiang A are analyzed,and the key techniques of high yield seed production of variety Yexiang A are put forward.The main techniques are as follows:reasonable arrangement of safe heading poplar flowering period,stress on the cultivation of strong male parent,balanced fertilization,construction of high yield seedling frame of female parent,dwarfing cultivation,cutting leaves for seed production,focusing on rice smut disease,fine strip disease control and so on,for reference of the vast number of farmers and technicians engaged in seed production of Yexiang A.
