Problems solved by technology

[0004] The existing poplar planting method mainly adopts the branch seedling raising method to carry out the cutting cultivation of seedlings in the nursery. The three-year-old seedlings in the nursery are transplanted and planted on the mountain after cutting the stems at a high position. Using this method for planting, the poplar trees will grow after 3 to 5 years. Unable to grow normally, the trunk and crown of adult trees aged 5-6 years are prone to moth disease, resulting in low yield rate, high planting cost, low economic efficiency, and not suitable for regeneration
After planting with the existing planting method, the output per mu of 4-year-old poplar is about 10 tons. The stem borer disease is serious, which directly leads to a decrease in yield and low wood quality. The planting of ordinary fast-growing poplar usually uses pesticides to kill insects, prevent disease, treatment, serious environmental pollution

Embodiment 1

[0034] The cultivation process of the bagged seedlings of GKT88 poplar is as follows: at the end of February, get 2-year-old robust seedling trunks (cutting seedlings) from the GKT88 poplar seedling nursery, soak them in 0.01% sodium naphthalene acetate solution for 24 hours, and treat the cuttings with roots The cutting seed value is in the nutrition bag. When the cutting is planted, cut the end of the cutting into the soil by 20-25cm, cut it into a slope with an angle of 40-50°, and cut the top into a plane, and the plane is 2cm away from the reserved sprout; After reaching about 150cm, the bagged seedlings of GKT88 poplar are obtained;

[0035]Step (1) GKT88 poplar bagged seedlings are transplanted and planted in the planting hole. The planting hole is 60 cm wide and 50 cm deep; 10 kg of organic fertilizer, 200 g of superphosphate and 100 kg of soil are mixed and filled in the planting hole; planting 2 After ~4 months, apply 200g of urea to each sapling; the spacing between...

Embodiment 2

[0039] The cultivation process of the bagged seedlings of GKT88 poplar is as follows: at the beginning of March, get 1-3 year-old strong seedling trunks (cutting seedlings) from the GKT88 poplar seedling nursery ground, soak 2h in solution with ABT1 rooting powder 120 mg / kg, After the rooting treatment of the cutting seedlings, the value of the cutting seed is in the nutrient bag. When planting the cutting, cut the end of the cutting into the soil by 20-25 cm, cut it into a slope with an angle of 40-45°, and cut the top into a plane. The distance between the plane and the reserved The sprouts are 2 to 3 cm long; after they grow to 130 to 150 cm, the bagged seedlings of GKT88 poplar are obtained;

[0040] Step (1) GKT88 poplar bagged seedlings are transplanted and planted in the planting hole. The planting hole is 60cm wide and 60cm deep; mix 5kg-10kg of organic fertilizer, 250g of superphosphate and 80kg of soil, and fill it in the planting hole; After 3 months, 300g of urea w...

Embodiment 3

[0044] The cultivation process of bagged seedlings of GKT88 poplar is as follows: at the beginning of March, take 3-year period 1-year-old robust seedling trunk (cutting seedling) from GKT88 poplar seed nursery at the beginning of March, use ABT1 No. rooting powder 150 mg / kg, soak in solution for 1.5h, and cut After the seedling rooting treatment, the cutting seed value is in the nutrition bag. When the cutting is planted, cut the end of the cutting into the soil by 20-25cm, cut it into a slope with an angle of 45-50°, and cut the top into a plane, and the distance from the plane is reserved for emergence. The buds are 2-3cm; when they grow to 160-180cm, the bagged seedlings of GKT88 poplar are obtained;

[0045] Step (1) GKT88 poplar bagged seedlings are transplanted into the planting hole. The planting hole is 70 cm wide and 60 cm deep; mix 5 kg of organic fertilizer, 300 g of superphosphate and 80 kg of soil, and fill in the planting hole; plant 15 days after urea 100g, 300...

Abstract

The invention discloses a new planting method for white poplar (poplar GKT88). The method includes the following steps of firstly, digging planting pits during the rainy season each year for planting seedlings of poplar GKT88; secondly, conducting low-position rod cutting on the portion, above tree roots, of stem rods of poplar GKT88 in the period between the first ten days of February and the first end days of March in the second year after plantation; thirdly, conducting watering to promote the seedlings to sprout after low-position rod cutting is conducted on the seedlings of the poplar GKT88, implementing fertilizer applying, watering and weeding management after 1-5 leaves of each seedling come out, and growing the seedlings into adult poplar GKT88 3-4years later. The new planting method is easy to operate, short in growth period, capable of lowering cost, fewer in plant disease and insect pest, high in yield and high in economic benefit.

Description

technical field [0001] The invention belongs to the field of planting technology of poplar "Northern tree and south species", in particular to a kind of poplar [0002] (GKT88 poplar) new planting method. Background technique [0003] Poplar (Populusalba in Latin name) belongs to the northern species of broad-leaved forest. After domestication and breeding, it can be planted in the south. After planting, it can grow fast and can regenerate ten times after felling. It belongs to the "North Tree South Species" of the State Forestry Administration As a popularization project, poplar trees require little water after domestication and breeding, and the water absorption is only 20% of that of ordinary species. After they become mature, the main trunk above 15m has no branches. It is suitable for planting in areas below the altitude of 2500m in the south. [0004] The existing poplar planting method mainly adopts the branch seedling raising method to carry out the cutting cultivat...
