编者:遵照毛主席“广积粮”的教导,为了把郊区农业生产进一步搞上去,根据广大贫下中农和知识青年的要求,我们增辟了《农业科技讲座》专栏,系统介绍有关作物栽培、育种、植物保护、土壤肥料、农业微生物等方面的科学技术知识,供大家参考。现在先介绍水稻的基础知识。由于我们水平有限,缺乏经验,一定有不少缺点,请读者批评指正. 水稻是我国的主要粮食作物,占粮食作物面积的四分之一,产量占三分之一以上,上海郊区水稻面积约有三百二十万亩,复种面积近六百万亩。近年来水稻单产虽有’提高,但还远不能适应我国社会主义建设和支援世界革命的需要。因此,掌握水稻的生长发育的规律及其形态、生理等特点,进一步搞好科学种田,促进水稻增产,是十分重要的。
Editor: In line with Chairman Mao’s guide on “wide food rationale”, in order to further promote agricultural production in the suburbs, according to the requirements of the vast number of poor and middle-level peasants and young intellectuals, we have added a column entitled “Lectures on Agricultural Science and Technology” to systematically introduce the cultivation of crops , Breeding, plant protection, soil fertilizers, agricultural microorganisms and other aspects of scientific and technological knowledge for your reference. Now introduce the basic knowledge of rice. Due to our limited level and lack of experience, we must have many shortcomings, please readers criticism and correction. Rice is China’s major food crops, accounting for a quarter of the area of food crops, accounting for more than one-third of the output, Shanghai suburbs rice area of about There are 3.2 million mu of multi-species area of nearly 6 million mu. Although the yield of rice has risen in recent years, it still can not meet the needs of socialist construction and support of the world revolution in our country. Therefore, it is very important to master the law of growth and development of rice and its morphological and physiological characteristics to further improve the scientific farming and increase the yield of rice.
