早稻是全年三季粮食作物中比较稳产高产的一季,在全年粮食产量中占有极重要地位。1978年我省早稻在战胜了中期低温和后期高温干旱的自然灾害后,又夺得了丰收。全省“全年粮食亩产三千斤试验”协作单位(以下简称“攻三千”协作单位)的早稻也取得了较高的产量。因此,认真总结和分析各协作单位早稻高产技术,对于早稻的高产更高产,全年粮食亩产超三千以及推动大面积生产都具有重要意义。根据64丘广陆矮4号和19丘军协及温选青的苗茎穗粒资料统计,依其每亩穗数和每穗粒数的协调关系,可归纳为三条高产途径:
Early rice is the season of more stable and high-yielding grain crops throughout the year and occupies a very important position in the annual grain output. In 1978, early rice in our province won a good harvest after it overcame the natural disasters of mid-term low temperature and late high temperature and drought. The province’s “annual grain per mu production of three thousand kilograms of test” collaboration unit (hereinafter referred to as “attack three thousand” cooperative unit) of the early rice has also achieved a higher yield. Therefore, earnestly summarizing and analyzing the high-yielding early-rice techniques of various cooperative units is of great significance to the high-yielding and high-yielding of early rice and the annual grain output of over 3000 and the promotion of large-scale production. According to 64 QiuGuangLuai 4 and 19 QiujunXie and Wen Xuanqing seedlings stems and granary statistics, according to their coordination between the number of spikes per panicle and grains, can be grouped into three high yielding ways:
