我县1964年试种水稻成功,1965年开始大面积推广。随着稻田面积的不断扩大,水田杂草也一年比一年严重,特别是稗草、牛毛草,板地蓑、三棱草,繁殖快,再生力强,与水稻争肥,争光,争温,严重影响水稻生长。秧田发生草荒后,造成拔秧困难,延误插秧季节;大田发生草荒后,一般减产二、三成,重的减产五成以上.贫下中农迫切要求消灭草害,确保水稻安全生长。
My county succeeded in experimenting with rice in 1964 and started to promote it in large scale in 1965. With the continuous expansion of paddy fields, weeds in paddy fields are also getting worse year by year.

After grassland shortage occurs in seedling fields, it causes difficulties in pulling seedlings and delays the season of rice transplanting. After the grassland shortage occurs in the fields, the general reduction in output by 20% to 30% and the heavy reduction in output by 50%.
