豫西南山前稻区属籼、粳稻过渡地带,特殊的气候条件、土壤类型和生产习惯等因素导致异地成熟的旱育壮秧技术不适应于本地。为解决水稻旱育秧秧苗素质差、水稻产量低且不稳的生产实际问题,研究了旱育秧田培肥、适期精量稀播、秧田覆膜、药剂浸种等旱育壮秧技术。结果表明,综合应用上述关键技术所培育的秧苗,成秧率达80%~90%,秧苗素质好,单株分蘖多,秧龄弹性大,抗逆性强,比习惯旱育秧增产28.17%,达极显著水平。 Southwest of Henan is a paddy region before Indica, Japonica transitional zone, special climatic conditions, soil types and production habits and other factors leading to off-season mature drought seedling technology does not adapt to the local. In order to solve the problem of low quality and instable production of rice seedlings in paddy field, the techniques of fertilizing and fertilizing in nursery field, seedling thinning in suitable period, seedling filming in seedling field and seed soaking with medicinal plants were studied. The results showed that the seedlings planted by the above key technologies were 80% -90% of the seedlings, the seedling quality was good, the number of tillers per plant was large, the seedling age was large, the resistance was strong, and the yield was 28.17% Very significant level.
