Problems solved by technology

But its defect is that it is not cold-resistant, and can only grow in areas south of 26 degrees north latitude, where the climate is higher, and areas with lower temperatures between 26 and 30 degrees north latitude are rarely planted, and this area has abundant rain all year round, mountain ponds, There are many rivers, lakes and ports, and the land is fertile and slightly acidic, which is especially suitable for the growth of eucalyptus. If eucalyptus can be introduced to this area, it will make a significant contribution to the development of the local economy and the improvement of people's living standards.

specific Embodiment approach

[0014] [Specific embodiments] The present invention will be further described by the following examples.

[0015] The inventor used 200 acres of barren hills in Lixian County, Hunan Province to try to plant Dunn's eucalyptus and meranti. After three years of planting and management, it has grown into a large eucalyptus forest with a height of 13-15m and a thickness of 11-13cm. Lush and gratifying, its cultivation method comprises the following steps:

[0016] 1, species selection: the eucalyptus plant tree selected by the inventor is Eucalyptus durn and Eucalyptus meranti, because these two kinds of eucalyptus all grow fast, are more cold-resistant, strong to environmental adaptability, woodiness is good.

[0017] 2, seedling breeding: the breeding method of seedling raising and cutting seedling raising of the clone adopted by the inventor. Among them: Seedling multiplication is a seedbed picking nursery composed of nutrient bag seedlings. Put the original tissue-cultured se...

Abstract

The invention discloses a method for cultivating hardy eucalyptus forests suitable for climates at north latitude of 26-30 degrees. The method comprises the following steps: determination of the varieties of eucalyptus trees, wherein eucalyptus dunnii and meranti are selected as the varieties of eucalyptus trees; seedling raising: carrying out propagation of the seedlings by using a clonal cutting seedling raising method or a method for growing seedlings by using seedlings, when cut seedlings grow to 12-25 cm, taking the seedlings out of greenhouses for transplanting; transplanting; carryout out post-transplanting management; and preventing and controlling plant disease and insect pests. Because the climate of zones at the north latitude of 26-30 degrees are sunny, rainy and many rivers, reservoirs and ponds are located in the zones, the characteristics that eucalyptus trees are heliophilous and absorbs much water can be satisfied; in the process of planting, through artificially applying fertilizers containing nitrogen, phosphorus, potassium, calcium, magnesium, a large number of organic matters, trace elements, amino acids and microbes and some active substance fertilizers, the effectiveness of nutrients can be increased; and compound fertilizers suitable for the growth of eucalyptus trees are applied to surviving seedlings every year, so that the characteristic that the eucalyptus trees absorb more fertilizer can be satisfied, therefore, eucalyptus trees artificially planted by using the method disclosed by the invention can averagely grow 4-6m in height and 3-4cm in DBH(diameter at breast height) each year, the eucalyptus trees can be cut down in batches in 4-5 years generally, and the wood yield per mu is 10-12 m<3>.

Description

technical field [0001] The invention relates to a cultivation method of eucalyptus forest, in particular to a cultivation method of cold-resistant eucalyptus forest suitable for the climate of 26-30 degrees north latitude. Background technique [0002] Eucalyptus is an evergreen broad-leaved fast-growing tree of the family Myrtaceae. It is native to Australia and is one of the three famous fast-growing tree species in the world. use. Because of its rapid growth and hard and delicate wood, it has great commodity value. It is not only a good material for making furniture, artificial boards, railway sleepers and electric poles, but also the best raw material for pulp in the paper industry. But its defect is that it is not cold-resistant, and can only grow in the south of 26 degrees north latitude, where the climate is higher, and it is seldom planted in the region with a lower temperature between 26 and 30 degrees north latitude, and this area has abundant rain all year round,...
