(一)用紅砒粉末作為種子消毒處理藥劑,對於幼苗感染性的小麥腥黑穗、小麥稈黑穗及燕麥堅黑穗等,有極良好的防治效果。但對大麥堅黑穗及條斑病,則不見功。(二)紅砒使用得法,對於麥種絕對無害;而且對於大麥、小麥的清潔種子,有積極的增產作用;惟對於燕麥還未能肯定。(三)紅砒粉末的拌種用量,當以種子重的0.025—0.05%為準簧僦?.005%,仍有殺菌效果。(四)為了增大藥物的容積,使得微量的紅砒粉末能够均勻週到地沾着每一麥粒,可用滑石粉、木灰末、甚至消石灰、草木灰或過磷酸鈣來稀释。(五)麥種拌砒後,須經一定期間的貯藏後播種,方顯出其强大的殺菌防病效果珉S拌隨種,則效果较少。至貯藏期間的久暫,則當因季節和用量等等而異。大致可以一個月為度。(六)紅砒使用不得其法,易起藥害。而藥害有無的關键,主耍在於拌砒後貯藏中的濕度,其次才是温度。如充分乾燥,在酷暑的氣候條件(37℃)下,貯藏7個月,尚??無妨礙。至於播種時的地温土濕,則關係極微。(七)紅砒的藥害與麥種處理當時的含水量有密切關係.含水量多,極為蝛U;含水量在12%以下,即安全無礙。(八)在自然狀况下用紅砒處理麥種,應當避去炎夏季節。又麥種拌砒前,必須充分晒乾。拌砒後,必須貯置高燥處所。
(A) with red yeast rice powder as a seed disinfection agent, the seedling infected wheat Tartarus, wheat stalk black spike and oat black spike, etc., has a very good control effect. However, black barley barley streak and disease, then no gain. (B) The use of red yeast rice is absolutely harmless to wheat germplasm; it also has positive stimulation effects on clean seeds of barley and wheat; however, it has not yet been confirmed for oats. (C) the amount of seed dressing powder, when the seed weight of 0.025-0.05% prevail spring 僦? .005%, there is still bactericidal effect. (D) in order to increase the volume of drugs, making trace amounts of red yeast rice powder evenly and thoroughly stained with each grain of wheat, available talc, wood ash, and even slaked lime, ash or superphosphate to dilute. (E) After mixing wheat straw, to be sown after a certain period of storage, the side showed its strong bactericidal disease prevention and control Min Min S mix with the species, the less effective. A long time to storage period, then when the season and dosage and so on. Can be a month for the degree. (Vi) Hongjiao use of its methods, easy to play drug injury. The key to the existence of phytotoxicity, the main lies in the storage of humidity after mixing, followed by the temperature. If fully dry, in the heat of the weather conditions (37 ℃), storage for 7 months, yet without hindrance. As for the soil temperature when sowing wet, then the relationship is minimal. (G) of red tamarind and the wheat seed injury is closely related to the water content of the moment when the water content is very high, U; water content of 12% or less, that is, safe and accessible. (H) in natural conditions with red croaker to deal with wheat, should avoid the summer season. Before mixing with wheat, you must fully dry it. After mixing, you must store high dry place.
