表一所列的药量系辽宁省的经验,黑龙江省与吉林省的用量应适当增高,南方省份应适当降低。莠去津与西玛津的性质稳定,在土壤中可维持较长的残效,施药一次即能保证整个生长季节不生长杂草。在春季风大干旱地区应于秋季翻耕或春耕后施药,将药液喷于地表,然后用圆耙纵横耙地(耙深10厘米)。甲草胺多采用播后苗前施药法,但在干旱的条件下用播前混土法,则能增强药效。 The quantities listed in Table 1 are based on the experience of Liaoning Province. The dosage of Heilongjiang Province and Jilin Province should be appropriately increased, while the southern provinces should be appropriately reduced. Atrazine and simazine are stable in nature and have long residual effects in the soil, ensuring that weeds are not grown throughout the growing season once applied. In the spring arid areas should be plowed in the fall or spring after the pesticide application, the liquid spray on the surface, and then rake vertical and horizontal rake (rake depth of 10 cm). More alachlor after sowing seedlings before spraying method, but in arid conditions before sowing soil mixing method, can enhance the efficacy.
