Embodiment 1

[0029] Collection and storage of plum leaf holly seeds, and sowing seedlings:

[0030] (1) Seed collection: From May to June every year, when the seed coat of the holly holly fruit turns black, select a robust plant without pests and diseases, and pick the fruit.

[0031] (2) Seed treatment and storage: remove the peel and pulp of the fruit, rinse it, remove the diseased and shriveled seeds, and press the pure seeds with wet river sand (the water content is 20%, no water can be squeezed by hand, it is suitable for forming and feeling moist) 1:2 mass ratio mixing, low temperature storage for 9 months.

[0032] (3) Establish seedbeds for sowing: hoe the seedbeds and turn them in the sun for 3 days, spray evenly with 50 times dilution of formalin, cover with plastic film and seal them for 2 days, remove the cover, level the land, and sow after 2 days.

[0033] (4) Seed treatment: Take out the seeds in February of the second year, remove river sand, sundries and moldy and shrivel...

Embodiment 2

[0038] Planting under the forest of Acacia mazhan in a field experiment station

[0039] When the holly holly seedlings are 30cm high, move them into the Acacia japonica forest with a canopy density ≤ 40% for planting (cut down the weeds and shrubs under the Acacia japonica forest before planting, and keep the plant species that can be used as medicine or have other uses), along etc. The high line opened a planting belt of about 30cm in the gap between trees, and dug holes in the planting belt. The size of the hole was 30×30×30cm, the spacing between plants and rows was 1×1m, and the compound fertilizer was applied at 0.1 kg / plant. No tending management was done after planting. grow naturally. The undergrowth that was not planted with holly was used as a comparison.

[0040] The average height of the surveyed plants in 5 years is 2.3m, and the average diameter at breast height is 1.3cm, forming a good understory plant layer. According to the harvest method, the root weight pe...

Abstract

The invention discloses a method for economic planting under southern low-efficiency artificial forests. The method comprises the following steps: collecting ilex cornuta seeds in May to June of the first year, removing peel and pulp, mixing the seeds with wet river sand according to a ratio of 1:2, and storing at low temperature; taking out the seeds in February to March of the next year, sowingand carrying out seedling raising after the seeds are treated through gibberellin, transplanting seedlings into nutrition cups when seedlings have 3-4 true leaves, transplanting the seedlings into theforest with a certain canopy density when the seedlings are 30 cm high, wherein holes are dug along contour lines, the hole size is 30*30*30 cm, the planting spacing is 1*1 m, and 0.1 kg of compoundfertilizer is applied per hole. The method is simple in planting, convenient to operate, easy to apply and popularize, and capable of harvesting in the fifth year and increasing forestry operation benefits, and therefore the purposes of quality improvement, efficiency improvement and sustainable operation of the low-efficiency artificial forests are achieved.

Description

technical field [0001] The invention belongs to the technical field of forestry and forest management, and in particular relates to a method for economical planting of low-efficiency artificial forests in southern China. Background technique [0002] In order to facilitate forestry operations, reduce pests and diseases, and the competition of shrubs and grasses for nutrients and resources, and increase the utilization efficiency of trees for light, water, and nutrient resources, traditional forestry operations such as smelting and chopping have become common forest management measures and have been widely used for decades. With economic development, global climate change and other ecological issues have become the focus of attention. Mountain smelting and chopping destroy soil structure, cause soil organic matter and nutrient loss, affect aboveground and underground species composition and richness, change soil microenvironment, reduce soil microbial activity and its decompo...
