花生施用燃煤烟气脱硫副产物研究初报

主要研究了施用燃煤烟气脱硫副产物（石膏和粉煤灰）对花生性状的影响。结果表明，在广东浅海沉积砖红壤上，施用脱硫副产物对盆栽花生出苗、根系及其营养生长、花生花针生长发育等均产生一定的抑制作用；抑制程度与脱硫副产物施用量有关。但在添加1%、5%、10%的脱硫副产物条件下，花生根瘤数量及质量均比不施脱硫副产物的处理有成倍地增加，若添加量达到20%则会对根瘤生长繁殖产生明显的抑制。施用脱硫副产物提高了花生的产量，在施用量达到土壤质量1%的条件下，花生获得最高产量，且根瘤生长繁殖受到促进，故该施用量是该实验的最优处理。

Study on the use of desulphurisation products in planting peanut in a pot-experiment

The effect use of desulphurisation products on peanut properties is studied in this paper, and the results showed that it can restrain peanut's shoot come out, stunt both peanut's root system growth and plant development in a pot-experiment, however, the degree that it affects peanut lie on the quantity of desulphurisation products that append in soil. The use of desulphurisation product stimulate peanut's root nodule in special way, on the condition that the rate of desulphurisation products reaches 1 percent, 5 percent and 10 percent, the quantity and weighty of root nodule is increased in great degree compared to the treatment without using desulphurisation products, but it restrains root nodule breeding and growth when the rate reaches to 20 percent. The use of desulphurisation products can enhance peanut output and, when the appliction rate reaches to 1 percent, the topmost output is obtained and peanut's root nodule growth is stimulated, therefore, the application rate is the optimal in this experiment.
