This paper reports a three years experiment results of twelve kinds of berbicides controlling soybean field weeds. Prescription which soybean field weeds in whole growth period could be prevented and eliminated by only a single teatment were proposed:1) sethoxydin + fonnsafen + surface active agent; 2) sethoxydin + pursuit, 3) bifenox + acetochlor. 65 days after using the herbicide, the weeding effects of above three prescriptions in small plots were 95. 4% , 93. 6% , and 93. 4%, respectively. Meanwhile,...

This paper reports a three years experiment results of twelve kinds of berbicides controlling soybean field weeds. Prescription which soybean field weeds in whole growth period could be prevented and eliminated by only a single teatment were proposed:1) sethoxydin + fonnsafen + surface active agent; 2) sethoxydin + pursuit, 3) bifenox + acetochlor. 65 days after using the herbicide, the weeding effects of above three prescriptions in small plots were 95. 4% , 93. 6% , and 93. 4%, respectively. Meanwhile, the weeding effects in large field experiments were 95. 6% , 95. 5% , and 93. 1 % , respectively. The twice hazards and residual amounts of form-safen and bifenox have been measured so that the safety using doseage of two herbicides to the post -stubble crop were determined. The cultivating model which was made up of the land leveling (plough and harrowing)-sowing (fertilizing)-medicining--harvesting was established. The experimental results showed that limited cultivating method with single herbicide treatment and no manpower and no second cultivation treatment was available to preventing and eliminating the weeds harm on th soybean field for whole growing season.

本文报道了三年来对12种大豆田除草剂的筛选结果,并从中优化出一次用药即可防除大豆田全生育期杂草的配方:1、稀禾定+氟磺胺草醚+表面活性剂;2、稀禾定+普杀特;3、甲羧除草醚+乙草胺。上述三个配方小区试验除草效果(施药后65d)分别为95.4%,93.6%和91.4%,较大面积田间示范除草效果(施药后65d)分别为95.6%,95.5%和93.1%。对氟磺胺草醚及甲羧除草醚的二次药害和残留量进行测定,确定了两种除草剂对后茬作物的安全用量。建立了整地(翻、耙)——播种(结合施肥)——用药——中耕培土(一次)——收获的栽培模式。试验结果证明,利用除草剂一次性防除大豆田全生育期杂草危害,并免去人工除草和两次中耕的少耕栽培方法是可行的。

prevention and cure peanut leaf spots by controlling primary infection source had been studied during 1986~1991. The results verified the soil purification had significant effect on preventing the disease. The pot culture experiment showed the disease occur 70,15 and 5 days later respectively in the controlling area than the control,and the controlling effect recorded on 30,July was 100%,91.3% and 62.4% respectively.

Until 30, August, the controlling effect was still kept at 99.3%, 43.1% and 30.8%, The protective effects of controlling primary infection source were also apparently in the field, Each treatment spraying the mixture of germicide and herbicide to blockade the ground pathogen germicide proved to be eddective before 10,August. The effect ranged from2.11% to 46.8L%.Better treatments are CuSO_4+Lasso,Baycor+Acetochlor.

自1986到1991年对控制初侵染源防治花生叶斑病进行了试验。结果表明,净化土壤具有显著的防病作用,盆栽控制区较对照区发病3年分别晚70天、15天和5天。7月31日调查,防效依次为100%、91.3%和62.4%,8月30日仍达99.3%、43.1%和30.8%。封锁初侵染源田间防病效果也很明显,播后用杀菌剂与除草剂混合喷洒封锁地面病原菌,8月中旬前各处理效果为2.11%~46.8%,较好的处理为硫酸铜+拉索、百科+乙草胺。

In order to effectively controll the growth of weeds in the nursery,and to provide enough seedlings of higher gualitg for plantation,we have selected a few new types of forestry chemical harbicide Oxyfluorfen、Frifurlin、Acetochlor and Haloxyfop to ged rid of the weeds by experiments The results Showed that the efficiency of four chemical herbicide are quite satisfying, 87 to 98 percent of the weeds were killed. It Is indeed a kind of chemical herbicide for nursery,therefore worth popularizing....

It Is indeed a kind of chemical herbicide for nursery,therefore worth popularizing.

果尔(Oxyfluorfen)为森林苗圃优良除草剂,苗床剂量600ml/hm2(23.5%乳油),60天内除草效果达90%~96%;出苗后喷施果尔300ml/hm2混合盖草能(Haloxyfop)(12.5%乳油)300ml/hm2,除草效果更佳.氟乐灵(Frifuralin)对针叶树园地,苗期用量2250ml/hm2(48%乳油)除草效果达87%~98%,但施药后需洗苗,并复盖0.5~1.0cm的红心土对苗木安全,其残效期可达4个月左右.乙草胺(Acetochlor)防除单子叶杂草有特效,是阔叶树种苗圃的良好除草剂.除草剂使用方法简便,一般采用药土或常规喷雾施药,除草效果好,经济效益显著.
