specific example

[0023] A specific example of the three-dimensional cultivation method of elephant grass and eucalyptus of the present invention, comprises the steps:

[0024] 1) Basic situation of forest land and seedlings

[0025] The experimental forest land is located in the Wujia branch of the state-owned Qinlian Forest Farm in Guangxi, covering an area of ​​11hm 2 , the highest altitude is 120m, the terrain is flat, the transportation is convenient, the drainage is good, the mountainous yellow soil is loose and fertile, and the soil pH value is 5.6. The main vegetation in the forest are Bidenspilosa L., Eleusine indica (L.) Gaertn.), Bermudagrass (Cynodondactylon (Linn.) Pers.), Conyzaecanadensis (L.) Cronq.) And dandelion (HerbaTaraxaCi) etc. Eucalyptus seedlings are 'Guanglin No. 9' tissue-cultured light matrix seedlings cultivated by Guangxi Academy of Forestry, and elephant grass is an excellent variety 'Guimu No. 1 Hybrid Elephant Grass' provided by Guangxi Animal Husbandry Resear...

Abstract

A method for three-dimensional cultivating pennisetum purpureum and eucalyptuses includes the steps of preparing eucalyptus planting areas; three-dimensional cultivating pennisetum purpureum and eucalyptuses; tending management of pennisetum purpureum and eucalyptuses; and rear period management of pennisetum purpureum and eucalyptuses. Since eucalyptuses are tall, heliophile and deep-rooted, and pennisetum purpureum is low, shade tolerance and shallow rooted, pennisetum purpureum is planted between rows of an eucalyptus planted forest to establish a three-dimensional eucalyptuses and herbage ecological composite group, promote growth of eucalyptuses, and make full use of ground and underground nutrition spaces. The biological yield and land utilization efficiency per unit woodland area are improved, sand and soil are reserved, and water and soil loss can be reduced. Ecological sustainability is maintained, and eucalyptus industrial transformation and efficient construction are promoted.

Description

technical field [0001] The invention belongs to the technical field of compound planting of forest farmers and herbage, and in particular relates to a three-dimensional cultivation method of elephant grass and eucalyptus. Background technique [0002] Eucalyptus (Eucalyptus) is an evergreen tree of the Myrtaceae genus Eucalyptus. It is native to Australia and is the main tree species used as raw materials for industrial papermaking. a lot of uses. Eucalyptus plantations are developing rapidly in my country's Guangxi, Guangdong, Fujian and other related cities and counties. By 2015, the planting area in Guangxi has reached 50 million mu, ranking first in the country, and the amount of eucalyptus trees accounts for more than 70% of the country. Eucalyptus has played a major role in alleviating the contradiction between national timber supply and demand, promoting the development of the integrated wood pulp and paper industry, maintaining national timber security, increasing f...
