1976年《科学实验》杂志发表了“突破杂交高粱难吃关”一文后,引起了全国有关生产和科研单位的重视,纷纷来信来访,要求引种试种,为了支持群众性的科学实验活动,我站于1977年春向23个省市197个单位寄发了配套原种。经过一年来各省市有关单位的试验鉴定,不少单位对“津杂九号”做了书面总结。这些材料对于考察津杂九号的适应范围,研究其栽培规律,探索增产措施,以及改进繁育方法都提供了宝贵的经验和充分的依据。一、津杂九号的产量表现与适应范围在52份总结材料里,按不同自然条件选择具有代表性的39个单位的试验示范产量列于表一。
After the publication of the article “Breaking Through the Unfavorable Cross in Sorghum”, in 1976, Science Experimentation attracted the attention of relevant production and research institutes all over the country. They all sent letters to visit and request the introduction of seed cultivation. In order to support mass scientific experiment activities, I Standing in the spring of 1977 to 197 units in 23 provinces and cities to send the supporting species. After a year of tests and appraisals of relevant units of various provinces and cities, quite a few units made a written summary of “Tianjin Miscellaneous No. 9”. These materials provide valuable experience and sufficient basis for investigating the adaptability of Tsuna 9, studying its cultivation rules, exploring stimulation measures and improving breeding methods. I. Performance and Adaptation Scope of Zina 9 Out of the 52 summary materials, the representative experimental production of 39 units selected according to different natural conditions is shown in Table 1.
