草害是我区粮油生产大敌。全区每年因草害损失粮食1000多万公斤,损失油菜籽400多万公斤。经过1985、86两年的多点试验,证明用氟乐灵除草效果好。尤其对一年生禾本科杂草,防除效果达85—90％。1987年在全区推广氟乐灵除油菜田杂草8.52万亩,增产油菜籽190.8万多公斤;1988年推广使用10万亩,增产油菜籽210万公斤。取得了显著的经济效益,很有推广价值。
Grass damage is my enemy of grain and oil production. The whole area lost more than 10 million kilograms of grain due to grass damage and more than 4 million kilograms of rapeseed. After 1985,86 two years of multi-point test, that trifluralid weeding effect. Especially for annual grass weeds, control effect of 85-90%. In 1987, we promoted 852,000 mu of trifluralin in rapeseed oilseed rapeseed fields and increased the output of more than 1908000 kilograms of rapeseed. In 1988, it promoted the use of 100000 mu and increased the output of rapeseed by 2.1 million kilograms. Achieved significant economic benefits, great promotional value.
