以对白背飞虱具有不同抗性的水稻品种嘉花1号(抗白背飞虱粳稻品种)和汕优63(感虫杂交稻)为试材,研究了不同杀虫剂处理对水稻害虫数量及稻米品质和产量的影响,并对其经济效益进行了评估.结果表明,无杀虫剂处理的嘉花1号上白背飞虱的高峰虫量仅为汕优63的1/10,在整个水稻生长季节,嘉花1号上的白背飞虱种群数量始终处于经济危害水平以下,而汕优63却受到白背飞虱的严重危害;无杀虫剂处理的蜘蛛数量比农户管理小区高3～7倍.不施用杀虫剂处理的嘉花1号和汕优63的产量分别下降11.8%和43.4%.与不施杀虫剂处理相比,1次杀虫剂处理的嘉花1号和汕优63的实际经济收入分别下降0.9%～2.6%和2.6%～4.7%,完全不施用杀虫剂时,汕优63的实际经济收入减少32.9%～36.1%,而嘉花1号反而增收2.2%～4.8%.此外,无杀虫剂处理嘉花1号的稻谷收入为9403元.hm-2,明显高于3种杀虫剂处理的汕优63(8632元.hm-2).杀虫剂处理不影响嘉花1号和汕优63的稻米加工、外观和食用品质,却降低了其蛋白质含量.
The rice varieties Jiahua 1 (anti-Siphonain rebaudiana japonica) and Shanyou 63 (susceptible hybrid rice) with different resistance to Sogatella furcifera were used to study the effects of different insecticides on rice pest populations And the impact of rice quality and yield, and evaluated its economic benefits.The results showed that the peak insects of Jiahua 1 without phytotoxicity were only 1/10 of that of Shanyou 63, Throughout the rice growing season, the population of whitebacked planthopper in Jiahua 1 was always below the level of economic hazard, while Shanyou 63 was severely damaged by whitebacked planthopper. The number of insects-treated spiders was lower than that of peasant households 3 to 7 times higher than that of the control group.The yield of Jiahua-1 and Shanyou-63 without pesticide treatment decreased by 11.8% and 43.4% respectively.Compared with the non-applied insecticide treatment, 1 and Shanyou 63 decreased by 0.9% -2.6% and 2.6% -4.7% respectively. The actual economic income of Shanyou 63 decreased by 32.9% -36.1% when no pesticides were applied at all. However, Jiahua 1 But increased by 2.2% ~ 4.8% .In addition, non-pesticide treatment Jiahua 1 rice income of 9403 yuan.hm-2, significantly higher than the three kinds of pesticides to deal with the Shan 63 (8632 yuan .hm-2). Insecticide treatment did not affect Jiahua 1 and rice processing, appearance and eating quality Shanyou63, but reducing its protein content.
