Detailed Description
The technical solution of the present invention is further described in detail by the accompanying drawings and embodiments.
The present invention provides an ecological afforestation method suitable for semi-bare rocky mountainous regions, as shown in fig. 1, in which a preferred embodiment of the present invention is shown.
Specifically, the ecological afforestation method suitable for the semi-bare rock mountain land comprises the following steps:
A. cleaning root systems of the seedlings which are suitable for growing, aligning root systems, bundling the seedlings into small bundles, and dipping the treated seedlings which are suitable for growing into roots by using yellow mud for later use.
Preparation before planting: cleaning soil particles and stones attached to the root system of the nursery stock suitable for seedling growing, cutting off overlong fibrous roots, main roots and weak roots, aligning root systems, bundling the nursery stock into small bundles, and positioning the bundling ropes at the upper parts of the roots and the stalks. Then the treated seedling is treated by the yellow mud root dipping technology for standby.
Preferably, the step of dipping the root in the yellow mud comprises the following steps:
a. uniformly stirring a starch grafted acrylate water-retaining agent and the alien soil according to the proportion of 1 (200-300); b. after being uniformly mixed, 600-700 kg of water, 2-3 kg of phosphate fertilizer, 8-10ml of PT mycorrhiza preparation and 100g of rooting powder are added into per cubic meter to be mixed into slurry; c. dipping the treated bare-rooted seedling root system of the seedling suitable for growth into the slurry, and taking out the root system after the root system is completely wrapped by the slurry.
The starch grafted acrylate water-retaining agent is a high-molecular water-absorbing material and has strong water-retaining property. After rainfall or irrigation, the water-retaining agent absorbs and stores redundant water in the soil including fertilizer dissolved in water, and slowly releases the water when needed by the plant, so that the water required by normal growth of the plant can be ensured, evaporation, leakage and loss can be prevented, the water is wasted, the service life of the plant-growing water-retaining agent is as long as 2 years, and the plant-growing water-retaining agent can repeatedly absorb and release water and is slowly used by the plant.
Further, the PT mycorrhiza preparation is prepared according to the principle that the plants form mycorrhiza under common conditions, and the beneficial plants survive and grow robustly under natural conditions. It is a broad-spectrum biological promoter, and has the functions of inducing and promoting plant to form mycorrhiza, raising plant's ability to absorb water and fertilizer, raising plant's disease resistance and stress resistance, raising soil activity, increasing soil organic matter content, improving soil, preventing water loss, protecting ecological resource and promoting ecological balance.
Before planting, the root system of bare-rooted seedling is dipped in slurry to wrap the root system of seedling with slurry and form a yellow slurry dipping layer 1 on the root system. The method can protect the seedling root system, enhance the bonding capacity between the root system and the soil, prevent the seedling root system from losing water for a long time and improve the planting survival rate.
B. And 2 hours before planting, watering the half-bare rock mountain land thoroughly to loosen the parent rock of the base layer. After 2 hours, digging a cylindrical planting pit with the diameter of 80cm and the depth of 50cm at the watering position, and removing bedrock gravels at the bottom of the pit. According to the characteristic that the bare rock cliff of the mountain of the semi-bare rock is irregularly distributed, the planting pit distance does not need to pit at fixed points according to the conventional standard specification, and the pit digging position can be flexibly changed and selected.
C. And placing a polyurethane sponge matrix barrel 2 which is 10cm thick and matched with the planting pit in shape into the planting pit, filling the polyurethane sponge matrix barrel 2 with the first-pass soil with the thickness of 10-15 cm to form a first soil layer 3, and flattening and compacting.
The polyurethane sponge matrix barrel 2 is a novel environment-friendly light matrix which is organically combined by matrix materials, nano materials and high-molecular materials, and has the advantages of reasonable pore structure, water retention, air permeability, no plant diseases and insect pests, high rot resistance and survival rate of plant root systems, light weight, degradability, long service life, no need of fertilization within 5 years and the like.
Preferably, the polyurethane sponge matrix barrel is prepared by reacting water-retaining filler, water, polyurethane polymer and polyol, wherein the mass content of the water-retaining filler is 45-50%, and the water-retaining filler is coconut shells, rice hulls, plant compost or pearl stones. The polyurethane polymer and the polyalcohol react and solidify to obtain a fixed structure of the matrix barrel, and meanwhile, the water-retaining filler is added to obtain the polyurethane sponge matrix barrel with both water absorption and shape retention so as to be used as a planting container for semi-bare rock mountain lands.
D. Putting the seedlings which are treated by dipping the yellow mud into roots and are suitable for growing into planting pits, filling soil with the thickness of 30-35 cm for the second time to form a second soil layer 4, righting the seedlings for planting, filling soil in layers and compacting, wherein the planting depth is 3-5 cm deeper than the top of the tree roots;
E. after planting, water is enlarged and poured thoroughly, a polyvinyl chloride weather-proof dripless dustproof film 5 is covered on the hole surface of the planting pit, and then daily maintenance is carried out.
According to the principle of 'properly fitting trees' to the growing seedlings, perennial seedlings which are fast in growth, good in protection performance, strong in stress resistance and suitable for growing in local climatic environments are selected. Preferably, the healthy nursery stock is one or more of drought-resistant and barren soil such as pinus sylvestris, spruce, white birch, juniper, white bark pine, platycladus orientalis, persimmon tree, jujube tree and tamarix chinensis, and is slightly influenced by climatic factors such as climatic altitude. Preferably, in the middle mountain area, the scierogenous seedlings are one or more of acer pentandra, acer negundo, wild peach, ulmus davidiana and sea buckthorn. Preferably, in the low mountain area, the economic tree species are suitable for growing, and the suitable seedling is one or more of wild apricot, narrow-leaved oleaster, hawthorn, crabapple, apple and amorpha fruticosa.
The ecological afforestation method suitable for the semi-bare rock mountain land can realize quick afforestation, improve the stress resistance of plants, enable the adaptability of the plants to severe environments, promote the growth of the plants and improve the survival rate of nursery stocks in the semi-bare rock geological region.
