一、抛栽需具备的基本条件1.抛秧本田田面要求抛秧本田田面要达到“平”、“净”、“糊”。“平”即田面平整,经过耕翻,旱整水耙后,田面做到高低不过寸,寸水不露泥。田面不平,抛栽前撤水后,高处无水层,也无悬浮泥,地表硬而板,秧苗盘根土坨不易砸入;低处水层较深,土坨落下因水层的缓冲作用也不易入泥,使秧苗多呈卧伏状态或漂在水面即漂秧。“净”即田面要干净,无残茬、秸秆和杂草。田面存有这些杂物,秧苗落在上面会影响秧根与田土结合而漂秧,遇风刮到田边而枯死。“糊”即土壤表面呈泥浆状,软硬适中。水耙地后,沉浆时间不能过长,否则泥浆变硬,抛后秧苗土坨入土太浅或呈卧状态,立苗时间延长。根
First, throwing the basic conditions to be equipped with 1. Throwing rice transplanted Honda requires the surface to throw rice transplanted Honda to reach “flat ”, “net ”, “paste ”. “Ping ” that the field level formation, after plowing, dry rake, the field to achieve the level of inch, inch of water without mud. Uneven surface, throwing planted before the withdrawal of water, the height of the anhydrous layer, there is no suspended mud, hard and board the surface of the paddy soil packing is not easy to break into; low water depth, soil lump falling due to the buffer layer The role is not easy to enter the mud, so that the seedlings were mostly lying or floating in the water surface that is drifting seedlings. “Net ” That the field should be clean, no stubble, straw and weeds. The presence of these sundries on the field, seedlings fall on the top will affect the combination of seedlings and field and drift seedlings, the case of wind blowing edge to die. “Paste ” that is muddy soil surface, moderate hardness. After the water rake, the sinking time can not be too long, otherwise the mud hardens, after throwing the seedling soil Tuo too shallow or lying state, Li Miao time extension. root
