地区农科所于八月二十二至二十三日,召开了早稻良种选育第二次协作会议,到会代表有各县农科所、良种场和社队试验点共37人。地区科委和农业局也派代表出席会议指导。会议交流了各试验单位的试验结果和生产试验,提出80年早稻良种布局与试验的意见。地区农科所副所长祝贤滨同志参加会议并讲了’话,会议开得较好,现将收获简报如下:一、80年品种布局意见:首先分析今年旱季气侯特点是:生长前期遇低温降低了分蘖成穗数,中期多阴雨延长幼穗发育期增加了每穗粒数、七月份干旱高温逼熟、增加不实率降低粒重,后期括台风雨,造成落粒发芽。因此早稻生育期推迟,早熟品种因生长期延长而空前
On August 22-23, the Regional Agricultural Science Institute held the second collaborative meeting on breeding of early rice varieties. There were 37 pilot sites of agricultural science institutes, breeding farms and social teams in all counties. Regional Science and Technology Commission and the Bureau of Agriculture also sent representatives to attend the meeting guidance. The meeting exchanged the test results and production tests of various experimental units, and put forward the opinions on the layout and test of early rice varieties in 1980. Comrade Zhu Xianbin, the deputy director of the Regional Agricultural Science Institute, attended the meeting and made a remark. If the meeting opens well, the briefing will now be as follows: I. Opinions on the layout of the species for 80 years: Firstly, we will analyze the characteristics of the climate in this year’s dry season when: Reduce the number of tillers into the panicle, more rainy mid-term extended panicle per panicle to increase the number of grains per spike in July drought temperature, increasing the false rate to reduce the grain weight, late typhoons, resulting in falling sprouting. Therefore, the early rice growth period postponed, early maturing varieties due to the extension of an unprecedented growth period
