Problems solved by technology

[0003] At present, teak plastic container seedlings and bare-root seedlings are mostly used for afforestation in the society. Due to the serious root damage of bare-root seedlings when they emerge from the nursery, and the relatively extensive afforestation techniques mastered by the masses, the survival rate of afforestation is usually about 80%, which is relatively low.
Most of the plastic container seedlings use yellow heart soil, ponds and other seedling substrates. The root system of the teak seedlings cultivated is not developed enough, and the weight of the substrate is heavy. When afforestation, the container must be removed, which is easy to cause the soil mass to be broken. The labor intensity of afforestation on rocky desertification mountain land Large, low afforestation efficiency, low survival rate, and a large number of plastic film bags are discarded on the mountain, which has a negative impact on the ecological environment
Teak is an exotic tree species, and its afforestation technology is constantly being explored and improved. The existing seedling afforestation technology is not completely suitable for application in rocky desertification areas

Embodiment 1

[0032] In March 2006, the teak seeds were put into the mortar, and the peel was smashed while pounding, taking care not to injure the seed core. After removing the impurities, the clean seeds were obtained. The plump teak seeds were selected and soaked in water at 48°C Let the seeds swell for 18 hours to fully absorb water, then remove the seeds from clean water and drain the water. Sow the drained teak seeds evenly and densely on the sand bed that has been routinely disinfected. When sowing, every 1m 2 Sow 800 g of teak seeds and cover with a layer of river sand with a thickness of 0.5 cm. A degradable non-woven seedling bag with a size of 10 cm×12 cm was selected as the seedling container. Use huangni and conventionally treated coconut bran to prepare a substrate in a volume ratio of 7:3, put it into a seedling container, place the seedling container into a furrow, and cultivate it with fine soil around it to keep water and fertilizer. Disinfect with 0.5% potassium permang...

Embodiment 2

[0038] In April 2012, put the teak seeds into the mortar, turn them while pounding, smash the peel, be careful not to damage the seed core, and get clean seeds after removing impurities. Select plump teak seeds and soak them in water at 45 ℃ Let the seeds swell for 18 hours to fully absorb water, then remove the seeds from clean water and drain the water. Sow the drained teak seeds evenly and densely on the sand bed that has been routinely disinfected. When sowing, every 1m 2 Sow 800 g of teak seeds and cover with a layer of river sand with a thickness of 0.5 cm. A degradable non-woven seedling bag with a size of 10 cm×12 cm was selected as the seedling container. Use Huang Ni and conventionally treated coconut bran to prepare the matrix at a volume ratio of 5:5, put it into a seedling container, place the seedling container into a furrow, and cultivate it with fine soil around it, so as to retain water and fertilizer. Disinfect with 0.5% potassium permanganate solution the ...

Embodiment 3

[0044] In April 2013, the teak seeds were put into the mortar, and the peel was smashed while pounding. Be careful not to damage the seed core. After removing the impurities, the clean seeds were obtained. The full teak seeds were selected and soaked in water at 40 °C. Let the seeds swell for 20 hours to fully absorb water, then remove the seeds from clean water and drain the water. Sow the drained teak seeds evenly and densely on the sand bed that has been routinely disinfected. When sowing, every 1m 2 Sow 800 g of teak seeds and cover with a layer of river sand with a thickness of 0.5 cm. A degradable non-woven seedling bag with a size of 10 cm×12 cm was selected as the seedling container. Use Huang Ni and conventionally treated coconut bran to prepare the substrate by mixing the volume ratio of 3:7, put it into the seedling container, place the seedling container into a furrow, cultivate it with fine soil around it, so as to retain water and fertilizer. Disinfect with 0.5...

Abstract

The invention discloses a seedling cultivation and forestation method for rare tree species tectona grandis L.f. in a rocky desert area. The method is characterized by comprising the procedures of strong seedling cultivation, careful land preparation, seedling planting and management after planting, wherein strong seedlings are formed by performing container seedling cultivation on tectona grandis L.f. seeds, then a land is carefully prepared, the seedlings are planted when soil is wet after rain in February to March, and fertilizer and water management and pest prevention and control are required to be ensured after planting. According to the forestation method, the one-time forestation survival rate of tectona grandis L.f. in a karst rocky desert area is increased from 80 percent to over 95 percent, tectona grandis L.f. can be forested at one time without replanting, the forestation efficiency is improved, the vegetation recovery process of the karst rocky desert area is accelerated, the economic incomes of people in the karst rocky desert area are increased, and remarkable economic benefits, social benefits and ecological benefits are created.

Description

technical field [0001] The invention belongs to the technical field of forestry cultivation, and in particular relates to a method for growing seedlings and afforestation of precious tree species teak in rocky desertification areas. Background technique [0002] Teak ( Tectona grandis L.f.) also known as: annatto, chai teak, belongs to the verbenaceae teak genus deciduous or semi-deciduous large trees, the height of the tree can reach 40~50 m, and the diameter at breast height is 2~3 m. Naturally distributed in tropical countries or regions such as India, Myanmar, Laos and northern Thailand. It is famous all over the world for its excellent wood properties, and is known as the most important tropical timber tree species in the world. It enjoys the reputation of "King of Ten Thousand Trees", and it is even regarded as "National Treasure" in Myanmar and Indonesia. Since 1850 teak was popularized as plantation in tropical areas, its plantation scope has rapidly expanded to mo...
