为了探求光呼吸抑制剂——亚硫酸氢钠在北方粳稻生产上的应用技术和增加效应,我们于1981年,在辽宁省营口市稻区进行92亩试验,取得平均增产8～12%的良好效果;1982年又利用飞机航喷和人力机械喷施,都普遍取得良好的增加效果。一、材料和方法试验和示范在统一领导、组织、试验方案下进行。参加单位有营口市、县科委、农业局,省、县科学研究所,省及各县(区)国营农场、公社农科站、农科队等32个单位,40余处,1982年试验示范达3843.7亩。试材以丰锦品种和杂交稻黎优57为主,还有丰锦 A×C_(57)和常规品种沈农1033、初胜、辽粳五号、19—2—1、E—368等。在不同地方、不同土壤类型和肥力水平亩产800、1000、1200斤以上田块和不同栽培技术水平条件下进行。分人工喷施和飞机航喷两种。浓度为100、200、300ppm,分孕穗期、开花灌浆期喷施。喷施次数1～3次。共12个处理,以同期喷施
In order to explore the application technology and increase effect of photoresponsive inhibitor sodium bisulfite on northern japonica rice production, we conducted 92 mu experiment in 1981 in Yingkou City, Liaoning Province, and achieved an average yield increase of 8-12% Effect; 1982 aircraft jet and human use of mechanical spraying, have generally achieved good results. I. Materials and Methods Experiments and demonstrations are conducted under a unified leadership, organization and pilot program. The participating units are Yingkou City, Science and Technology Commission, Agriculture Bureau, Provincial and County Scientific Research Institutes, Provincial and County (district) state-owned farms, commune agricultural stations, agricultural teams and other 32 units, more than 40 trials in 1982 Demonstration of up to 3843.7 acres. The main samples were Fengjin variety and hybrid rice Liyou 57, as well as Fengjin A × C_ (57) and conventional varieties Shennong 1033, Chu Sheng, Liaojing No.5, 19-2-1 and E-368 . In different places, different soil types and fertility levels of 800, 1000, 1200 kg per mu plots and different cultivation techniques under the conditions. Sub-artificial spray and aircraft jet two. Concentration of 100,200,300ppm, bifurcation points, spraying flowering stage. Spraying times 1 to 3 times. A total of 12 treatment to spray the same period
