The application of Amygdalus pedunculata in sand control and sand stabilization
Technical field
The present invention relates to the application of Amygdalus pedunculata in sand control and sand stabilization, be specifically related to the application of Amygdalus pedunculata in sand control and sand stabilization through growing nursery and culture.
Background technology
China is a more serious country of local desertization degree, and desert and desertification land area have reached 165.3 ten thousand km
2, and just with annual 2460km
2Speed development, so the desertization problem of preventing and treating is subjected to the great attention of party and country ' s leader and governments at all levels, and has adopted various measures and actively prevented and treated.Through the desertization research and control of nearly half a century, the desertization control of China still faces the severe situation of " local improvement, the whole deterioration ", in four countermeasures that central authorities propose calendar year 2001, will recover and protect husky district vegetation to mention space of top prominence.In recent years, the artificial ecology woods has played significant effect in sand control.Yet, select the ecological forest to be difficult to make husky district vegetation to keep for a long time merely.The economic forest of how selecting to have an economic benefit carries out control of desert, and plantation and industrialization development are organically combined, thereby control of desert is dropped into by simple country to be carried out the transition to Sha Yangsha, and finally can obtain considerable economic well-being of workers and staff, it is new control of desert thinking, to accelerating control of desert, realize the sustainable development of control of desert, flourishing husky district economy is significant.
Amygdalus pedunculata has another name called wild cherry, be the machaka of rose family Amygdalus, once be distributed widely in the north, Shaanxi and Inner Mongol sand ground, cold-resistant drought-enduring, well developed root system, have good desert adaptability and sand control effect, and life cycle century-old above, almost do not have damage by disease and insect, management simply.
Amygdalus pedunculata is cold-resistant drought-enduring, and moisture capacity is good, has extremely strong desert survival ability.Under water stress and cold conditions, the polyphenoils enzymic activity in the Amygdalus pedunculata body significantly improves, and illustrates that these seeds have very strong drought resisting, cold tolerance.Conductance measurement shows: Amygdalus pedunculata low temperature semilethal temperature can reach-31 ℃, and is more cold-resistant than-21 ℃ of common almond.The Amygdalus pedunculata florescence is longer, blooms successively from tailo to Schattenseite, and the cold spell in spring in northern Shensi, area, Inner Mongol is had tolerance preferably.
The Amygdalus pedunculata well developed root system, wide accommodation, growth cycle is long, in case grow into forest, can protect soil for a long time and fix the sand, prevents sandstorm and water and soil loss, and can accelerate to desertify and the reverse process in desertification soil.Acrial part is the Amygdalus pedunculata about 90 centimeters only, and subterraneous root is crawled to spread and reached more than 30 meter, and is deep-rooted mutually, holds on to the sand dune as grid.
Summary of the invention
The purpose of this invention is to provide a kind of Amygdalus pedunculata and grow seedlings and do not have the irrigation water culture technique, use this technology domestication's Amygdalus pedunculata can be used for sand control and sand stabilization.
Implementation procedure of the present invention is as follows:
Amygdalus pedunculata is grown seedlings:
With 80~95 ℃ water logging kind, steeped 24~48 hours, mix 2/3rds sand, plastic mulching is waken up and is planted, and the back sowing of germinateing in 5~7 days grows to 50~80 centimeters of heights of seedling, and leading thread can be planted more than 0.3~0.8cm.
Amygdalus pedunculata does not have the irrigation water cultivation:
Plant in the fall, seedling is cut bar to more than the leading thread 35~45 centimeters, convert 3~8% potassium dihydrogen phosphate, 1.5~4% zinc fertilizer, 0.5~2% potassium permanganate in mud, dip in root with the mixed mud of converting, slip consistency is as the criterion to protect root; The depth of planting is cheated dark 40~50 centimeters, and leading thread is above buries 25~40 centimeters in soil, expose 5~12 centimeters, the hole is added flat.
Advantage of the present invention: wild Amygdalus pedunculata runs its course, and is distributed widely in the north, Shaanxi and Inner Mongol sand ground, and the kind shoot survival percent is very low, is difficult to play the effect of sand control and sand stabilization.Adopt the seedling growing process and the no irrigation water culture technique of Amygdalus pedunculata of the present invention, survival rate is more than 90~95%.Germinate early generally in early April, after surviving, 0.5~1 meter of average annual growth rate, part was bloomed in 2 years, bore fruit after general 3 years.After the commerial growing, can be used as the pioneer tree species of control of desert, play the sand control and sand stabilization effect.But this tree is normal growths all kind in desert and loess Qiu Lin gully district, and as machaka, both can cover sand ground and desertification soil life cycle more than a century, can produce a large amount of humus again, improvement desert and desert soil.
Embodiment
Embodiment 1 Amygdalus pedunculata is grown seedlings and anhydrous culture technique
Amygdalus pedunculata is grown seedlings: with the boiling water seed soaking of 90 degree, steeped 36 hours, mix 2/3rds sand, plastic mulching is waken up and is planted, and germinates in the 6th day, and the back sowing of germinateing is whenever broadcast 28 kilograms, 4.5 ten thousand strains of per mu yield seedling.Breed then, 65 kilograms of heights of seedling, leading thread is more than 0.5cm, and for well, the mid-term of growing seedlings can not lack of water, otherwise occurs the taproot seedling easily with many lateral roots for root, and influence is carried to plant and is survived.
The anhydrous irrigable culture process of Amygdalus pedunculata: plant in the fall, before and after the Beginning of Winter, seedling is carried bar to 40 centimeter (more than the leading thread), convert 5% potassium dihydrogen phosphate, 2% white vitriol with mud, 1% potassium permanganate is converted to become to mix mud and dip in root, and slip consistency is as the criterion to protect root.The depth of planting is cheated dark 45 centimeters, to bury 30 centimeters more than the leading thread in soil, exposes 10 centimeters, the hole is added flat, survives 92%.Germinate early generally in early April, after surviving, 0.78 meter of average annual growth rate, part was bloomed in 2 years, bore fruit after general 3 years.
Embodiment 2:
Husky district adopts annual kind of shoot survival percent of embodiment 1 anhydrous irrigable culture planting technology, stays the seedling rate can reach 90% in Shenmu County, shows good drought resisting performance.There is wax on the leaf surface, and moisture is difficult for distributing in the plant corpus.
30,000 mu of plantation Amygdalus pedunculatas, 50 mu of breedings, survival rate of seedling is cultivated survival rate 90% more than 95%.
