我县自1981年—85年对亚硫酸氢钠在小麦、棉花、大豆、红薯等作物的增产效应做了大量的试验示范,试验证明,它是一项投资少,见效快,收益大的新技术措施。一、试验方法几年来,我县针对高光呼吸作物籽粒瘦秕小花不实,器官脱落,产量不高等问题,进行了光呼吸抑制剂——亚硫酸氢钠的应用研究。利用小区试验和大区示范相结合,对不同作物的喷施时间、浓度及次数进行探讨,并在此基础上大面积推广应用。试验结
My county from 1981 to 85 years of sodium bisulfite in wheat, cotton, soybeans, sweet potatoes and other crops yield effect made a lot of experiments, the experiment shows that it is a less investment, quick, big new benefits Technical measures First, the test method Over the past few years, my county for the high light respiration crop thin Shizhuo floret false, organs fall off, the yield is not high, carried out a photorespiratory inhibitor - sodium bisulfite application research. Using the plot test and the demonstration of the large area, the spraying time, concentration and frequency of different crops were discussed, and on this basis, large-scale popularization and application were carried out. Test results
