土坑温床催芽法近年在我县银花、三里、石佛等社队重点推广,它比老法催芽量大、均匀、省时、稻种出芽早二、三天,成熟期相应提早,同时抗灾增产。具体做法是:挖坑:选向阳避风、北面靠墙的地方,挖成深1.5尺(将挖出的土培在四周,这样坑深可达2—2.5尺),宽3尺,长度不限的长形土坑,并在坑底挖一条深宽各3—4寸的贮水沟。然后在坑底铺3—4寸稻草,再覆盖草袋或芦席,这样铺设好酿热催芽坑。温水淘种:为了提高种子堆的温度,缩短催芽时间,种子进坑前,先用45—50℃的温水浸淘,进行予热,随即将种子放入
In recent years, in our county Yinhua, Sanli, Shifo and other communes, the germination of soil pit has been greatly promoted. Compared with the old method, the germination rate is large, uniform and time-saving. The germination rate of rice seed is two days earlier and three days earlier, Resilience increase. The specific approach is: Digging: Choose sunny shelter, the north side of the wall, dug into a deep 1.5 feet (the soil will be excavated in four weeks, so pit depth up to 2-2.5 feet), 3 feet wide and an unlimited length Of the long-shaped earth pit and dug in the bottom of a 3-4 cm wide and deep water storage ditch. And then shop in the bottom of the pit 3-4 inch straw, and then covered with grass bag or reed mat, so laying a good hot crater. In order to increase the temperature of the seed heap and shorten the germination time, before the seed enters the pit, it should be pre-heated with 45-50 ° C warm water and then the seed is placed
