为检阅科学研究成果和交流生产经验,北京市蔬菜学会于1964年4月13—15日举行了第一届学术年会。出席会议的有科研、院校、业务领导、农场及公社等单位的代表和来宾共150余人。这次年会共收到论文30篇,宣读了17篇。 有关栽培方面的论文有13篇,其中《五年来京郊大白菜生产技术总结》的报告中,从充分的调查数据论述了北京地区大白菜的适宜品种、整地、播种适期、合理密植、灌溉、施肥及病虫防治的基本经验,同时指出了京郊大白菜生产中存在的问题。《大白菜田间整齐度与产量的关系》一文中指出:大白菜植株生长整齐与否对产量有很大影响,目前生产上大白菜田间整齐度差异悬殊,大株满心菜只占24.9-55.3％,如何使半数以上的菜长好,增产潜力还很大。《大白菜经济施肥》的报告中,论述了大白菜叶球形成与营养水平的密切关系,指出增施氮肥是促进大白菜营养器官发育的重要因素,并以大量的数据指出:苗期、莲座期、结球始期、结球中期四个不同发育阶段施肥对白菜增产效果有显著差异,其肥效最高增产幅度最大的是结球始期,还指出施肥的高效期和外界气温等条件有一定关系。此外,《1963年春季甘兰早期抽苔调查小结》报告中指出:北京地区1963年甘兰早期抽苔普遍发生,是因为苗期光照充足、温度高、幼苗较往年生长快,而定 In order to review the scientific research results and exchange production experience, Beijing Vegetable Society held its first academic annual meeting on April 13-15, 1964. More than 150 representatives and guests from scientific research institutions, business leaders, farms, communes and other units attended the conference. This year a total of 30 papers were received, read 17 articles. There are 13 essays on cultivation, of which the report summarizes the production techniques of Chinese cabbage in the suburbs in the past five years. Based on sufficient survey data, the paper discusses the suitable varieties of Chinese cabbage, soil preparation and sowing date, reasonable close planting and irrigation , Fertilization and pest control. At the same time, it pointed out the problems in the production of Chinese cabbage in the suburbs of Beijing. “Chinese cabbage field uniformity and yield,” one article pointed out: Chinese cabbage plant growth or not have a significant impact on the yield, the current production of Chinese cabbage field uniformity disparity, large strains of cabbage only accounted for 24.9-55.3% How to make more than half of the dishes grow well, yield potential is still great. “Chinese cabbage economic fertilization,” the report, discussed the formation of cabbage leaf ball and nutrient levels are closely related, pointed out that the application of nitrogen fertilizer is to promote vegetative organs of Chinese cabbage important factor, and a large number of data that: seedling stage Period, the beginning of the ball, the middle of the ball during the four different development stages of fertilization cabbage yield significantly different effects, the highest yield of its highest yield is the beginning of the knot, also pointed out that the fertilization of the effective period and the outside temperature and other conditions have a certain relationship. In addition, the “1965 survey of early winter bolting survey,” the report pointed out: early 1963 in Beijing kulan bolting generally occurs because of sufficient light at seedling stage, high temperature, seedlings grow faster than previous years, and
