早稻蒸汽育秧是利用普通平房作育秧室,把谷种播在育秧座上,在室內依靠水蒸汽所带的热量和湿度創造一个高溫、多湿的育秧条件,以进行快速育秧的一种方法。它是1958年大跃进中我区农民在党的正确領导下破除迷信、解放思想、勇于革新的产物。实踐証明:一般已催好芽的种子运用这种方法育秧,經过5天左右的时間就能育出長3～3.5寸的秧苗。蒸汽育秧的好处:1.完全摆脱了早春低溫等不利自然因子对育秧的影响,从而有效地防止了早稻烂秧。一般成秧率可以提高到90～95％以上。2.秧龄短,成秧快,可以适时早插。移栽期一般比水田育秧可以提前15～30天;抗寒力較强的粳稻品种可提早到淸明前后插秧。同时,在水田育秧发生烂秧或秧苗不足时,采用蒸汽育秧可以比較及时地补救缺秧,达到保季节,保面积;3.育秧的全部过程在育秧室进行,不需秧田,劳力集中而节省,耗損种子少,每亩秧田可省下种谷15～20斤。因此降低了水稻生产成本。4.設备簡单,管理方便。这种新的育秧方法,虽具有以上的优点,但它究竟对水稻生長发育会产生那些影响,增产效果如何?在极短的育秧过程中,秧苗是怎
Early rice steaming seedling is the use of ordinary bungalows as seedling room, the seed sowing seedling in the seat, in the indoor rely on the heat and humidity brought by water vapor to create a hot, wet nursery conditions, in order to conduct a rapid seedling a method. It is the product of the peasants in our region under the correct leadership of the party during the Great Leap Forward in 1958 to break the superstition, emancipate the mind and be bold in reform. Practice has proved that: the general has been reminded of seed buds use this method of seedling, after about 5 days can grow 3 to 3.5 inches long seedlings. The benefits of steaming seedlings: 1. Completely get rid of the early spring low temperature and other adverse natural factors on the nursery, thus effectively preventing the early rice rotting seedlings. General planting rate can be increased to 90 ~ 95%. 2. Young seedling age, into seedling fast, early insertion can be timely. Transplanting is generally 15 to 30 days earlier than paddy seedling cultivation in paddy field. The japonica rice varieties with strong cold hardiness can be transplanted before and after the transplanting. At the same time, in the paddy seedling rotten seedlings or seedlings shortage, the use of steam seedling can be more timely remedial seedlings, to ensure the season, protect the area; 3. The whole process of seedling nursery room, without seedling, labor intensive and save , Less seed loss, seedling per acre can save 15 to 20 pounds of seed. Thus reducing the cost of rice production. 4. Equipment is simple, easy to manage. This new method of growing seedlings, although with the above advantages, but what exactly does it have on the growth and development of rice will have those effects, increasing yield? In the very short process of raising seedlings, seedlings is how
