檫树是我国南方特有的速生优良树种,它不仅生长快,材质好,是很好的用材林树种,而且树形优美,晚秋红叶,又是理想的风景树。现已被列入用材林基地主要造林树种,也广泛用作城市及四旁绿化。我省1970年前人工林只有4万亩,近年来已发展到一百多万亩。随着林业生产的不断发展,对檫树良种的要求越来越高,需要量也越来越大,但是,檫树结实率极低,根据我们调查平均仅5.4%,如何提高种子园的单株结实量,为生产提供更多的良种,已经成为进一步发展檫树必须解决的关键问题之一。檫树是我国特产,其分布中心又在我省,以前国内很少有人研究它,对其开花结实的规律等
Castanopsis tree is a unique species of fast growing superior species in southern China, which not only grow fast, good material, is a good timber forest species, and beautiful trees, late autumn leaves, but also the ideal landscape tree. Has now been included in the main timber plantation tree species, but also widely used as a city and surrounded by green. In our province, there were only 40,000 mu of plantations before 1970, and more than 1 million mu have been developed in recent years. With the continuous development of forestry production, the demand for the elm tree seed is getting higher and higher, the demand is also more and more, but the sturgeon tree rate is very low, according to our survey average only 5.4%, how to improve the single seed garden It is one of the key problems that must be solved to further develop poplar trees that the seed yield is strong and more seeds are provided for the production. Tamarix is our specialty, and its distribution center in our province, few people in the past to study it, its law of flowering and strong
