一、引言几年来,自己或多或少涉猎了一些有关水稻株形的问题。今天就讲这个问题。现在人们这样认为,自从1956年发现矮脚南特以后,六十年代南方各省水稻矮秆化,是我国水稻生产的第一次突破(当然包括与其相适应的一系列栽培措施的配合);到了七十年代,在矮化育种的基础上,杂交水稻的选育和推广成为我国水稻生产的第二次突破。于是有人问:到了八十年代能否在前两次突破的基础上,再来一个第三次突破?这就是1982年9月我们参加国家科委在杭州召开的论证会上议论的重点之一。
I. INTRODUCTION In the past few years, I have been involved in more or less some questions about the plant shape of rice. Today to talk about this issue. Now people think that since the discovery of Dwarf Nanant in 1956, the dwarfing of rice in the southern provinces in the 1960s was the first breakthrough in rice production in China (of course, including a series of cultivation measures in line with them); to In the seventies, on the basis of dwarf breeding, the breeding and popularization of hybrid rice became the second breakthrough of rice production in our country. So, someone asked: can we reach a third breakthrough on the basis of the previous two breakthroughs in the 1980s? This is one of the focuses we discussed at the demonstration held by the State Science and Technology Commission in Hangzhou in September 1982.
