去年,我市有200多亩旱种水稻覆膜田,由于草荒严重而造成毁种。覆盖地膜虽然能明显地提高地温,促进水稻生长发育,但容易造成杂草滋生。覆膜质量好,膜内高温、高湿,部份杂草会被蒸干枯死。而用杀草丹、灭草灵、除草醚等除草剂,能有效地防除禾本料杂草及阔叶草。 Last year, the city has 200 acres of dry cultivation of rice fields, due to severe grass shortage caused by species. Although covering the mulch can obviously improve the ground temperature and promote the growth and development of rice, it is easy to cause the weeds to breed. Film quality, membrane temperature, humidity, some weeds will be evaporated to dry. The use of herbicide Dan, weeding Ling, weed ethers and other herbicides, can effectively control the grass weeds and broadleaf grass.
