Tung tree cultivation method

Abstract

The invention discloses a tung tree cultivation method. The method comprises the steps that 1, seedling raising is conducted; 2, when planting is conducted in spring, gentle slopes which are loose in soil, exposed to sun, good in drainage and high in content of organic matter are selected, and the height above the sea level is controlled to range from 300 m to 900 m; 3, soil preparation and planting are conducted; 4, when planting is conducted, lifting is conducted gently after oil covering is conducted twice, covering is conducted till soil exceeds the portion 2-3 cm away from a mud door heart, and watering is conducted in time; 5, crops such as soybeans and peanuts are planted between the lines of planted tung trees; 6, when the height of oil tree seedlings reaches one meter, apical dominance is removed, first level branching is promoted at about one meter, the centremost branch is selected as a trunk of second level branches, when the height reaches 60 cm to 80 cm, second-level branching is promoted, the centremost branch is reserved to serve as a third level branch, when third level branching is completed, topping is conducted on all the branches, and the branches are controlled to longitudinally grow; 7, according to growth vigor and land masses of different plants, before flowering, a nitrogenous fertilizer and a potash fertilizer are mainly applied, and an appropriate amount of micro-element fertilizers are matched.

Description

technical field [0001] The invention belongs to the field of tung tree, in particular to a cultivation method of tung tree. Background technique [0002] Energy shortage and environmental pollution have become the main bottlenecks for the sustained and rapid development of the world economy today. Exploring, developing and utilizing renewable clean energy has become a global hotspot. Energy plants are a renewable and clean energy source, usually referring to plants that can produce products that are close to petroleum components and can replace petroleum or are rich in oil. Energy plants are processed to obtain biodiesel. Tung oil is a world-renowned industrial oil tree species, and it is also a very good energy plant. The oil squeezed or extracted from the seeds of Tung oil is called tung oil. Tung oil is a high-quality raw material for processing biodiesel. my country is the country of origin and main producer of tung tree, with a long history of cultivation and utiliz...

Problems solved by technology

At present, one of the bottlenecks restricting the development of tung oil industry is the low output of tung forest, with an average yield of tung oil per mu of 15-20 kg, which is still far from the reported maximum yield of 90-100 kg per mu. The main reason is that the suitable planting area is narrow , poor plant nutrition production, low survival rate

On the other hand, the traditional tung farming method has exacerbated hilly soil loss, decreased soil fertility, and reduced tung yield, causing serious harm to agricultural production and the ecological environment.
