Ecological cultivation technology for promoting quick establishment of newly-planted bamboo forest

Abstract

An ecological cultivation technology for promoting quick establishment of a newly-planted bamboo forest mainly comprises planting land selection and preparation, parent bamboo selection, parent bambootransportation and planting and management of a bamboo forest after planting and is characterized in that a grass-earthworm system is introduced during planting. By adopting the system, soil ripeningis rapid, the physical and chemical properties of soil are obviously improved, the survival rate of afforestation is improved, the quantity of newly-planted bamboos is greatly increased, a promotingeffect is also played on ground diameter increase, quick forest establishment is achieved, and the planting time can be shortened for 2-5 years compared with conventional forest establishment throughcrown closure.

Description

technical field [0001] The invention relates to an afforestation technology, in particular to an ecological cultivation technology for promoting rapid forestation of newly planted bamboo forests. Background technique [0002] Bamboo is a kind of plant belonging to the Gramineae Bambusadea (Bambusadea). It is an important fast-growing forest resource and an excellent landscaping plant. The stems of bamboo plants growing horizontally in the soil have obvious divisions, roots take root on the nodes, and there are buds on the sides of the nodes, which can germinate and become new underground stems or shoots to emerge into bamboo. Bamboo shoots contain a variety of amino acids and trace elements. Nutritionists believe that bamboo shoots are natural health food. It has high fiber content and low fat content, which can promote gastrointestinal digestion and excretion. Regular consumption of bamboo shoots can reduce the retention and absorption of harmful substances in the body. It...

Problems solved by technology

[0003] In order to promote the rapid growth of bamboo forests, the following cultivation techniques are mainly used at present: (1) increase the density of afforestation; (2) select bamboo forests with deep soil layers and good soil fertility; (4) Treat the canopy and apply fertilizer every year after afforestation; this method has the following disadvantages: it consumes a lot of manpower and financial resources, the cost of afforestation is high, the fertility utilization rate is low, the improvement of soil condition is limited, and it is easy to cause water and soil erosion. Runoff increases, and even causes water pollution

However, there are few earthworms in the bamboo forest, especially when the original topsoil is severely damaged, the newly turned soil is barren, the soil aggregates are severely damaged, the number of soil microorganisms and soil animals is small, and there is almost no earthworm activity. The soil structure is compacted and the fertility is low. The survival rate of afforestation in this area is low. The time for canopy closure and afforestation usually takes 5-10 years. The cycle is long, the effect is slow, and the yield is low.
