Abstract

The present invention relates to a method for controlling deserts by planting Jerusalem artichokes, which belongs to the technical field of the desert control of agricultural planting. The present invention is characterized in that the Jerusalem artichokes are planted in holes in the deserts, the method is divided into three parts of a splitting chopping method for making a seed, late seeding in spring and harvest, tubers are chopped into a size larger than 1cm <3>, and the tubers are mixed by plant ash, covered and disinfected. The tubers are planted into the dug holes in the late spring, depth is from 10 to 20cm, a planting region is divided into a main zone and an auxiliary zone, no harvest exists in the first year, sampling harvest is carried out in the second year, and the harvest does not influence sand fixation. The Jerusalem artichokes have the advantages of cold resistance, drought resistance, strong reproductive capacity, wind sand resistance and no diseases and pests, and are planted in bulk. The underground tubers and roots are used for tightly fixing sand due to the growth of self string roots, and terrestrial stems and leaves form a wind blocking zone, and thus, the method is the good method for controlling the deserts.

Description

The method that the plantation jerusalem artichoke is administered the desert

(1) technical field:

The present invention relates to utilize agricultural planting to administer the method in desert.

(2) background technology:

The desert area accounts for world land area 1/4 in the world today, and China land is 1/3 occupied by the desert, and also will enlarge 2464 square kilometres every year, and the desert is given the Nature and humanly brought huge disaster, make the earth lose the ecological balance, administering the desert is the task of top priority.China drops into large quantities of human and material resources sand controls already, adopting commonplace method is to break into grid with straw, corn stalk and other paddy grass on the desert on the desert, fixed the sand very big effect, but its cost height, waste many human and material resources, also to go year after year to do, only play sand fixation, can not change desert soil.Also have and in the desert, plant trees, herbage, adopt scientific method that it is survived, make the desert become the oasis, but its cost height is difficult for promoting.

(3) summary of the invention:

The invention solves the problem of administering the desert, sand control is effective, prevents that effectively the desert from enlarging, and changes the desert soil environment, and once plantation is permanent is benefited.

Technical scheme of the present invention is: cave kind jerusalem artichoke in the desert.Because jerusalem artichoke (ginger is not peppery) is cold-resistant drought-enduring, anti-blown sand, well developed root system string root, fertility is strong, and the plant of no damage by disease and insect can grow in the desert.

The invention has the beneficial effects as follows: the jerusalem artichoke tolerance to cold is strong especially, and the stem tuber hibernation below subzero 40～50 ℃ of sand is not dead, can continue spring to germinate.Drought-resistance ability is strong, when serious drought, and the death of jerusalem artichoke terrestrial stem, subterranean stem can grow new talent again in 1 year, and extremely strong vitality is arranged.Anti-blown sand, particularly spring and autumn, dust storm is serious, is no more than 50cm as long as cover sandy soil, and jerusalem artichoke normally germinates.Rely on their terrestrial stem density to autumn, highly form a slice shelter belt, stem tuber and root system are caught sandy soil, reach the purpose of fixing the sand.Fertility is extremely strong, annual speed increment with 20 times, and process of growth is without any need for management, no damage by disease and insect.Jerusalem artichoke grows year in year out, and its leaf, stem, the every death of root system have once just increased a large amount of detritus things to the desert, soil composition reaches change, when being fit to other crop of plantation, replant other crop, the stem tuber of jerusalem artichoke does not have chemical contamination, no poisoning is extraordinary pollution-free food, terrestrial stem, leaf are the good feeds of animal, and pollen is helpful to the honeybee class, and seed is the cuisines of birds, form new ecologic balance environment, bring huge economic benefit.

(4) embodiment:

Embodiment 1

The method in this improvement desert is a cave kind jerusalem artichoke in the desert, cuts apart the production of hybrid seeds of chopping method, spring late sowing and gather in the crops three parts.

Cut apart the production of hybrid seeds of chopping method: the jerusalem artichoke stem tuber is cut apart be cut into 1cm ³Above stem tuber stirs with ash, and pulp is sealed, and forms a kind of skin of similar epidermis, keeps seed moisture content, carries out disinfection simultaneously, and every mu of ground needs 10～15 kilograms in stem tuber seed.

Spring late sowing: in late spring, the jerusalem artichoke stem tuber grows the bud of leaf and pulls up from the stem tuber base portion, directly plants in the sand, make leaf expose the husky compacting of Shamian Island or leaf loam cake 2～3cm, remaining stem tuber is cut apart the chopping method and is made seed, digs the cave plantation, planting depth is 10～20cm, and wherein 15cm is best.Plantation divides master tape and subband, master tape is vertical with local prevailing wind direction, subband is vertical with master tape, master tape box haul bandwidth is narrowed down by wide by 100m～50m, spacing strengthens between 20～30m gradually between master tape and the master tape, plantation row, strain spacing 30cm～50cm, and the main air port master tape is wide, suitably strengthen density during plantation, subband density is rare.According to various places dust storm situation difference, the sowing time can be adjusted.

Results: the plantation jerusalem artichoke was not received in 1 year, was used to fix the sand.Because the jerusalem artichoke hibernation, germinate 1 year spring, and underground stem tuber and root system do not destroy, the jerusalem artichoke in 1 year can increase by 20 times, firmly fixes the sand by stem tuber and the root system of jerusalem artichoke, and is withered to 1 year stem, leaf, take to take out the receipts method, suitably take out receipts at major and minor band, reaching results does not influence and fixes the sand.Autumn, seed maturity was cut fruit, beat gently, promptly got seed, was beneficial to machine sowing.Sand control is effective.

Embodiment 2

The method in this improvement desert is a cave kind jerusalem artichoke in the desert, can directly the seed of autumn harvest be planted in the desert, and all the other are identical with embodiment 1.

Embodiment 3

The method in this improvement desert is a cave kind jerusalem artichoke in the desert, directly the jerusalem artichoke of results is cut apart in the chopping seed sand in autumn after the autumn harvest, and all the other are identical with embodiment 1.

Jerusalem artichoke also has resistance to overhead flooding injury, can plant on the mountain range, around the headwater, island, prevents erosion.
