Embodiment 1

[0029] A method for afforestation under a bamboo and cypress casuarina forest, the technical method comprising the following steps:

[0030] 1) Selection of forest land: choose casuarina near-mature forests, stands that are dominated by sandy and slightly acidic soil, with a gentle terrain, a slope of ﹤15°, facing a semi-sunny slope, a forest age of more than 25 years, and located at the back edge of the coastal backbone forest belt. Canopy density 0.6;

[0031] 2) Woodland cleaning and site preparation: In October, weeds in the casuarina stand were partially cleaned according to the planting point, all diseased and rotted trees were removed, the distance between the planting hole and the casuarina trees was kept at 1.5m, and the utilization rate of the forest land was 42%. , Dig holes according to the density of 2.5m×2.5m (45 plants / mu), the hole size is 50cm×40cm×30cm (hole surface×hole depth×hole bottom). Mix the surface soil and core soil thoroughly, backfill to 10cm abov...

Embodiment 2

[0041] A method for afforestation under a bamboo and cypress casuarina forest, the technical method comprising the following steps:

[0042] 1) Selection of forest land: choose casuarina near-mature forests, stands that are dominated by sandy and slightly acidic soil, with a gentle terrain, a slope of ﹤15°, facing a semi-sunny slope, a forest age of more than 25 years, and located at the back edge of the coastal backbone forest belt. Canopy density 0.5;

[0043] 2) Forest land clearing and site preparation: In November, the weeds in the casuarina stand were partially cleared according to the planting point, and all diseased and rotted trees were removed. The distance between the planting hole and the casuarina trees is kept at 1.8m, and the utilization rate of the forest land is 46%. The hole is dug according to the density of 2.5m×2.5m (49 plants / mu), and the size of the hole is 50cm×40cm×30cm (hole surface×hole depth × hole bottom), the topsoil and core soil are stacked sep...

Embodiment 3

[0053] A method for afforestation under a bamboo and cypress casuarina forest, the technical method comprising the following steps:

[0054] 1) Selection of forest land: choose casuarina near-mature forests, stands that are dominated by sandy and slightly acidic soil, with a gentle terrain, a slope of ﹤15°, facing a semi-sunny slope, a forest age of more than 25 years, and located at the back edge of the coastal backbone forest belt. Canopy closure 0.7;

[0055] 2) Forest land clearing and site preparation: in December, weeds in the casuarina stand were partially cleaned according to the planting point, all diseased and rotted trees were removed, the distance between the planting hole and the casuarina trees was kept at 2.0m, and the utilization rate of the forest land was 50% , dig holes according to the density of 2.5m×2.5m (53 plants / mu), the size of the hole is 50cm×40cm×30cm (hole surface×hole depth×hole bottom), when digging, the surface soil and the core soil are stacke...

Abstract

The invention relates to the field of under-tree forestation methods, and provides a podocarpus nagi casuarina under-tree forestation method. The defects that in the prior art, a podocarpus nagi plannting method is low in forest space utilization rate and low in yield, and the single creature can survive under the same forest are overcome. The method comprises the following steps of 1 forest selection, 2 forest cleaning and soil preparation, 3 nursery stock selection, 4 planting technology, 5 fertilization, 6 weeding and hole enlarging, 7 pruning, 8 flower and fruit management, 9 pest controland 10 fruit harvesting and storing.

Description

technical field [0001] The invention relates to the field of understory afforestation methods, in particular to an understory afforestation method of bamboo and cypress casuarinas. Background technique [0002] Bamboo cypress (Podocarpus nagi), also known as spinosa fir, mountain fir, bamboo leaf cypress, etc., is an evergreen tree species of Podocarpus nagi in the family Podocarpus. The roots, stems, leaves and seeds of bamboo cypress contain multiple chemical components and have high medicinal value. The seed oil of bamboo cypress can be converted into biodiesel through methyl esterification or ethyl esterification, the starch contained in the seeds is an excellent raw material for the production of bioethanol (biogasoline), and the utilization degree of comprehensive fuel oil (biodiesel, biogasoline) of the seeds It can reach more than 60%. It is an important fuel oil tree species in my country with high economic value. Bamboo and cypress have a long lifespan, and centur...
