研究结果提出了轻型栽培稻田化学除草的优良配方“丁恶复配”。每公顷施用１８００～２１００ｍＬ丁恶５０％ＥＣ，除草效果达９５％左右。建立了水稻安全出苗生态调控及其相应配套技术。明确了水稻出苗率（Ｙ）与土壤水分（Ｘ１）、施药剂量（Ｘ２）、浸种时间（Ｘ３）等各因素的相关式和影响程度，相关式为Ｙ＝１６９．６７－１．７６Ｘ１－０．０７Ｘ２－１．３３Ｘ３；各因素的影响程度分别为Ｘ１占５５．７％，Ｘ２占２．２％，Ｘ３占４２．１％，显示了土壤水分是影响水稻安全出苗的主要因子。试验还表明，控制４０％以下的土壤水分，是使用“丁恶”（Ｂｕｔａｃｈｌｏｒ＋Ｏｘａｄｉａｚｏｎｍｉｘｔｕｒｅ）的关键技术。苗期使用“优克稗十农得时”（Ｄｉｍｅｐｉｐｅｒａｔｅ＋Ｌｏｎｄａｘ）或“快杀稗十农得时”（Ｆａｃｅｔ＋Ｌｏｎｄａｘ），是克服直播稻田中后期草害的优良配套措施，控制草害的效果达９５％～１００％。
The results of the study proposed a light-weight cultivation of chemical weed good recipe “Ding evil complex.” Application of 1800 ~ 2100mL Ding Xie 50% EC per hectare, weeding effect of about 95%. The establishment of rice safety emergent ecological regulation and its corresponding supporting technology. The correlativity and influence degree between the emergence rate of rice (Y) and soil water (X1), application dose (X2), soaking time (X3) and other factors were clarified. The correlation was Y = 169.67-1.76X1- 0.07X2-1.33X3. The influence degree of each factor is 55.7% for X1, 2.2% for X2 and 42.1% for X3, which shows that soil moisture is the main factor that affects the safe emergence of rice. Tests also showed that controlling soil moisture below 40% was a key technique using Butachlor + Oxadiazonixix. The use of Dimepiperate + Londax or Facet + Londax in seedling stage is an excellent matching measure to overcome the grass-leaf damage in the direct-seeded rice fields in the late stage, and the control effect of grass damage is up to 95% ~ 100%.
