刺槐、棉槐是适于盐碱地造林的两个主要树种。但在缺少淡水灌溉的情况下,旱地育苗,春播易受干旱盐碱危害,雨季又怕大雨淤积和水涝,多造成缺苗断垅,出苗不齐,产苗量很低。近几年我们采取雨季后期育苗,因这时气温高,土地湿,盐分轻,种子发芽快,出苗齐,拿苗容易。一年半生的苗出圃,质量也高。不仅解决了本场造林用苗问题,而且大量的支援了周围社队。为迅速扩大苗木来源,今将具体作法介绍如下,供大家参考。
Robinia pseudoacacia, cottonseed is suitable for saline-alkali afforestation of two major tree species. However, in the absence of freshwater irrigation, nursery crops in the drylands are susceptible to drought and salinization in the spring, and are afraid of heavy precipitation and waterlogging during the rainy season. In recent years, we take nursery later in the rainy season, because of the high temperature, wet land, salt, seed germination, germination, easy to take seedlings. One and a half years of seedlings nursery, the quality is high. Not only solved the problem of afforestation seedlings, but also a large number of support for the surrounding community. In order to rapidly expand the sources of seedlings, we will introduce the specific practices as follows for your reference.
