【摘要】：土壤处理具有安全、高效、简易的特点,杂豆田用于土壤处理的除草剂较少,为实现杂豆田杂草安全高效防控技术。采用田间试验的方法,通过土壤处理筛选安全、高效杂豆田除草剂,研究其对杂豆的安全性、除草效果、农艺性状、产量等的影响,结果如下:1.红小豆土壤处理12%VA草酮3000m L/hm2;25%氟磺胺草醚1875~2250 m L/hm2+48%异VA草松1125~1500m L/hm2;25%氟磺胺草醚1500~1875 m L/hm2+12%VA草酮3000 m L/hm2,能够提高出苗率。25%氟磺胺草醚1875 m L/hm2+12%VA草酮3750 m L/hm2,株防效96.9%,鲜重防效87.0%,干重防效88.0%,增产5.31%;25%氟磺胺草醚1500 m L/hm2+12%VA草酮4500 m L/hm2,株防效96.5%,鲜重防效89.1%,干重防效89.9%,增产1.10%。2.绿豆土壤处理处理25%氟磺胺草醚1500 m L/hm2+48%异VA草松1125 m L/hm2出苗率与对照基本持平。株防效92.4%,鲜重防效94.5%,干重防效94.4%,增产7.11%。3.芸豆土壤处理33%二甲戊灵3750~4500 m L/hm2+50%扑草净1500~3000 g/hm2对芸豆的安全性高。33%二甲戊灵4500 m L/hm2+50%扑草净2250 g/hm2,株防效96.9%,鲜重防效93.6%,干重防效93.2%,增产23.51%。红小豆土壤处理25%氟磺胺草醚1500~1875 m L/hm2+12%VA草酮3750~4500 m L/hm2对红小豆具有安全、除草效果好、增产作用;绿豆土壤处理25%氟磺胺草醚1500m L/hm2+48%异VA草松1125 m L/hm2对绿豆具有安全、除草效果较好、增产作用。芸豆土壤处理33%二甲戊灵3750~4500 m L/hm2+50%扑草净1500~3000 g/hm2对芸豆具有安全、除草效果较好、增产作用。
[Abstract]:Soil treatment has the characteristics of safety, high efficiency and simplicity. There are few herbicides used in soil treatment in mixed bean fields, in order to realize the safe and efficient control technology of weeds in mixed bean fields. The effect of herbicide on the safety, weeding effect, agronomic character and yield of mixed bean was studied by using the method of field experiment. The results were as follows: 1. the effect of herbicide on the safety, herbicidal effect, agronomic character, yield and so on was studied. Red adzuki bean soil treatment of 12%VA grass ketones 3000ml / L / hm ~ 2 / 25% fluorosulfonate 1875 / 2250 m L/hm2 48% isoVA pine 1125 / 1500m / L / hm ~ 2; 25% fluorosulfonate 1 875 m L/hm2 12%VA oxanone 3000 mL 路hm ~ 2 could increase seedling emergence rate. 25% fluorosulfonate 1875 m L/hm2 12%VA 3750 mL 路hm ~ 2, plant control efficiency 96.9%, fresh weight 87.0%, control efficiency 96.9%. The control effect of dry weight was 88.0%, and the yield was 5.31%. The control effect was 96.5% for plant, 89.1% for fresh weight, 89.9% for dry weight and 1.10% for yield of 1.2%, respectively. The control effect of 25% fluorosulfonate 1500 m L/hm2 12%VA oxanone was 4500 mL / hm 2, the plant control effect was 96.5%, the control effect of fresh weight was 89.1%. The seedling emergence rate of 1500 m L/hm2 48% isoVA grass pine 1125 m L/hm2 in mung bean soil treated with 25% fluorosulfonate was almost the same as that of the control. The control effects of plant, fresh weight, dry weight and dry weight were 92.4%, 94.5%, 94.4% and 7.11% respectively. The soil treatment of kidney bean with 33% dimethopentyl 3750 m L/hm2 5 500 m L/hm2 50% Pucaocaojing 1 500 脳 3 000 g/hm2 was safe to kidney bean. 33% 2 methopentyl 4500 m L/hm2 50% Pucaocaojing 2250 g / hm 2, plant control 96.9%, fresh weight 93.6%. The control effect of dry weight was 93.2%, and the yield was 23.51%. The soil treatment of red adzuki bean with 25% fluorosulfamethoxyether (1500m / 1875 m L/hm2 12%VA) was safe for adzuki bean by 3750m / L/hm2. The effect of weeding was good, and the yield of red adzuki bean was increased. The soil treatment of mung bean with 25% fluorosulfon ether (1500m L/hm2) 48% isoVA grass pine (1125 m L/hm2) was safe for mung bean, and the effect of weeding was better and the yield of green bean was increased. The soil treatment of kidney bean with 33% dimethopentyl 3750 m L/hm2 5 500 m L/hm2 50% Pucaocaojing 1 500 脳 3 000 g/hm2 was safe for kidney bean, and had better weeding effect and higher yield.
