Embodiment 1

[0018] A planting method of plant tung tree, the steps are:

[0019] (1) Land preparation and soil collection: Before the winter comes and the soil freezes, dig holes in the selected afforestation land at a distance of 3m×3m. As the slope increases, the distance between plants and rows should also increase accordingly; The length is 0.8-1.2m, the width is 0.4-0.6m, and the depth is 0.4-0.6m; the excavated soil is stacked under the hole, dried, and stones, grass roots, and plant seeds are picked out, and large soil blocks are crushed; There are relatively few grass roots, seeds and gravel, so the soil taken out from the hole can be used directly, while the newly developed wasteland has relatively more grass roots, seeds and gravel, so a deeper soil layer should be selected when collecting soil.

[0020] (2) Preparation of nutrition package: select the old purchased or directly process new 1m×1m sack, put the soil taken out in (1) into it, and add water retaining agent (grafted ...

Abstract

The invention discloses a method of planting a tung tree, which comprises the following steps: (1) land and soil preparation: digging a hole according to the spacing span, piling the soil dug out below the hole, drying the soil, and removing stones, grass roots and plant seeds in the soil; (2) preparation of nutrition package: filling the dried and crushed soil into gunny bags, adding starch typewater retention agents, biological carbon particles and crushed corn straws into the gunny bags, and mixing the substances in the nutrition packages; (3) placement of the nutrition packages: scrapingthe surface vegetation in the position with the piled soil below the hole, placing the scraped turf in the dug hole, and putting the nutrition packages on the bare land with the vegetation scraped; (4) seed treatment: selecting large and plump seeds, soaking the seeds in warm water, and selecting the seeds settling into the water for use; (5) planting: planting the treated seeds at the center of each nutrition package; and (6) supplementing and thinning: filling up the gaps and thinning the thick seedlings after the seeds come out of the land. The invention solves the problems in the traditional method of planting the tung tree, such as narrow appropriate planting areas, poor nutrition and growth, low survival rate, and the conflict of cultivation and weeding against water loss and soil erosion.

Description

technical field [0001] The invention belongs to the technical field of ecological planting, and more specifically relates to a method for planting tung tree (Tunga trinidae), which is suitable for planting tung tree in hilly areas in southern China. 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. [0003] 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 p...
