本文采用田间试验与室内测定相结合的方法,研究了新马歇特和丁草胺对秧田、直播稻田水稻秧苗的安全作用和应用技术。用抑制水稻中浓度的研究方法,明确了新马歇特保护水稻安全出苗的部位是种芽,保护作用的大小为:催芽>浸种>不浸种;还明确了该除草剂只有当土壤湿度为35％-50％时,这种保护作用才能显示出来;该药用于秧田、直播稻田均能随播随用,既可充分灭草,又能保护稻种安全出苗,生长;在施药剂量、时间、方法相同的条件下,新马歇特与丁草胺具有同样的除草效果。说明新马歇特是秧田、直播稻田的优良除草剂之一。
In this paper, the combination of field test and laboratory test was used to study the safety and application of neo-machete and butachlor in rice seedlings of seedling and direct seeding rice fields. With the method of inhibiting the concentration in rice, it is clear that the site of new gerbil protection of rice is a kind of sprout, the protective effect is: germination> soaking> non-soaking; it is also clear that the herbicide is only when the soil moisture is 35 % -50%, this protection can be displayed; the medicine used in seedling field, direct-seeded rice fields can be used along with the broadcast, both full weeding, but also to protect the safe seedling growth; growth in the application dose, Time and method under the same conditions, the new mastic and butachlor have the same weeding effect. Description New Marshall is one of the finest herbicides for seedling, direct-seeded rice fields.
