Abstract
The invention discloses a method for cultivating fast-growing bamboo willow, and relates to the field of fast-growing tree planting technology. The method mainly comprises the following seven steps: (1) selection of cultivation land, (2) site preparation and fertilization, (3) planting of seedlings, (4) management of water and fertilizers, (5) trimming of branches, (6) soil loosening and weeding, and (7) pest control. According to the invention, the method not only overcomes defects that the previous fast-growing bamboo willow is insufficient in moisture and nutrients, undeveloped in root system in the plough layer, low in survival rate, irregular in growth and poor in quality, but also reduces the cultivation cost, shortens the growth cycle and improves the quality of trees.
Description
Technical field:
The present invention relates to fast growing tree planting technology field, be specifically related to the cultivation method of a kind of fast-growing bamboo willow.
Background technology:
Fast-growing bamboo willow has another name called U.S. bamboo willow, to be trembled with fear willow, korean willow, osier willow, mao bamboon assortment of genes selection cross by the U.S., there is the forest rising star of new generation of polynary genetic germplasm gene, it has the features such as hypervelocity life, resistance, material are good, high density, be one urgently high-quality hypervelocity leaved for development give birth to new forms of energy seeds.Within its very short till now time of being born, be just subject to showing great attention to of woods industry experts and scientific research institution, the everybody being more subject to urgently getting rich fast pursues.
China scientific research personnel, in Energy Conversion Technology, has carried out the technological development such as solid molding fuel, alcohol fuel, biodiesel, biomass power generation/heat supply, and has developed the technical matters utilizing cellulose castoff ethanol production to fast-growing bamboo willow.Fast-growing bamboo willow has the feature of high heating value, high C/N ratio, high-biomass, the most applicable cutting cycle to energy seeds, rotation and specific yield requirement, is outstanding energy seeds.
Although China is since the end of the year 2007 introduced fast-growing bamboo willow kind, goes through and within 7 years, carried out cultivating, plant, study, apply and promoting, in the nursery of fast-growing bamboo willow, cultivation and plantation process, still had technical problem much to be discussed.For soil property and the climatic condition of China, invention describes a kind of Cultivation method of fast-growing bamboo willow.
Summary of the invention:
Technical problem to be solved by this invention is to provide the cultivation method of the fast-growing bamboo willow that a kind of growth cycle is short, damage by disease and insect is few.
Technical problem to be solved by this invention adopts following technical scheme to realize:
A cultivation method for fast-growing bamboo willow, comprises the following steps:
(1) selection of milpa: select soil effective layer thickness degree at more than 60cm, soil pH below 8.5, salt content divide lower than 15000ppm, non-lack of water saline land, beach ground, ait, continent, the middle of the river, marshland, wetland, not busy wasteland, border and the not substantially farmland of man-made irrigation or annual rainfall can be carried out in the hillside fields of more than 1000mm;
(2) site preparation and fertilization: basal dressing of first turning over before plantation, ploughing depth is 50-60cm, execute the farmyard manure 2000-2500kg that becomes thoroughly decomposed, soya-bean cake 45-50kg, Nitrogen, Phosphorus and Potassium 30-40kg and zinc sulphate 1-1.5kg for every mu, then grade, furrow are done by the wide 2-3m of furrow, furrow width 1-1.5m, ditch depth 25-30cm;
(3) Seeding planting: carry out Seeding planting in about 10-15 days before bamboo willow nursery stock fallen leaves, before field planting, naked seedling base portion half is soaked 12-24h in water, again seedling is put into limewash during field planting and soak 10-15min, plantation density is determined according to the diameter of results growth timber, and sufficient normal root water is watered on field planting limit, limit;
(4) water and fertilizer management: in good time water after field planting, the direct water content of woodland guarantees more than 18%, early growth period every mu imposes urea 20kg, superphosphate 30kg, growth every 15-25 days in mid-term waters a water, every mu imposes urea 30kg or carbon ammonium 100kg, superphosphate 20kg, Later growth every mu imposes potash fertilizer 20kg, imposes 2-3 time;
(5) branch is pruned: carry out the winter to the coming year before germination after fallen leaves in autumn and cut, and the main top side shoot pruned middle and lower part side shoot and affect tree-shaped, carries out the summer and cut between May to August, main pruning eugonic side shoot, close branch and damage by disease and insect branch;
(6) weed with a hoe: carry out intertillage in good time and loosen the soil and weeding, keep soil from packing together, increase the gas permeability of soil and prevent weeds and nursery stock from fighting for soil nutrient and moisture;
(7) extermination of disease and insect pest: during newborn branch one month, control once, high temperature season control once, cloudy weather for several days running seasonal control once, with chlorophos 800-1000 times of liquid high-pressure fog pest control, have rot and canker can on limb scab in length and breadth interval 0.5cm cut the tool marks deeply reaching xylem, then be coated with soda water or the thiophanate methyl of 15% caustic soda or 1:10-12, late November, upwards 0.5m was high with quicklime brushing trunk Horizon.
Nitrogen, Phosphorus and Potassium containing 3-5% in normal root water in described step (3).
Plantation density in described step (3) plants 300 plants/acre for gathering in the crops bamboo willow big-diameter wood standard, and central diameter material standard plants 400 plants/acre, over-short-fell plantation 2000-5000 plant/acre.
The invention has the beneficial effects as follows:
(1) solve in the past fast-growing bamboo willow moisture and oligotrophy, plow layer root system is undeveloped, survival rate is low, it is irregular to grow and material is poor shortcoming;
(2) according to different growing stage feature, suitably topdress, thus reduce cultivation cost;
(3) according to results bamboo willow diameter determination plantation density, thus sufficient solar radiation is ensured;
(4) strict milpa is selected to shorten growth cycle, improves trees quality.
