Abstract
The invention relates to a cultivation method of seedlings of limonium gmelinii of saline-alkali soil in an arid region. The method comprises the steps of digging parallel shallow ditches in the saline-alkali soil, and making rectangular pieces of land in the field according to a certain area; carrying out flood irrigation and furrow irrigation on the rectangular pieces of land in the field, eluting salinity to enable a seedbed to be in a low-salt state, and further simulating the naturally occurring conditions of the seedlings; guaranteeing the successful planting of the seedlings of the limonium gmelinii by 'furrow irrigation and seeding in water'. The cultivation method is respectively used for planting tests in Karamay Xiaoguai township, Fukang desert ecology station of Chinese academy of science and Karamay carbon sink forest base, and the tests prove that the seedling rates of the limonium gmelinii are more than 70%, so that the technological reserve is accumulated for greening and beautifying the saline-alkali soil in the arid region.
Description
Technical field
The invention belongs to ecologic planting field, relate to arid region saline-alkali soil halophytes limonium gmeliniiKuntze seedling breeding method.
Background technology
China's saline-alkali soil area is large, and the national all kinds of saline-alkali soil gross area reaches 1,000,000 km
2, about have 100 cities and towns to have saline land to distribute.Expand along with city size and industrial pattern needs, some new cities and towns, infant industry garden, processing trade district and logistics center are also constantly built on saline land, but the saline and alkaline greening to cities and towns in soil, beautify and bring very large difficulty.Generally speaking, when upper soll layer salt content is more than 0.6%, most plants can not normal growth, only have some idioadaptations could grow in the plant of solonchak when soluble-salt content is more than 1.0%, therefore, the selection of saline land greening material and cultivation management are very important.Salt And Alkali Tolerance greening seedling has become the topic that relevant nursery stock production enterprise is concerned about with greening unit most.
Naringi crenulata is born in salination desert more, resistance to salt marsh and barren, is excellent ground cover plant and cut-flower material that is dry, fresh flower dual-purpose, has very large Development volue and market potential.Naringi crenulata special habitats determines its special economic worth, very worth at saline land greening, beautify in construction and apply.Although Xinjiang has abundant wild naringi crenulata resource within the border, also report is rarely had to the exploitation of the naringi crenulata having higher ornamental value.Although naringi crenulata can in salt marsh ambient growth, the seed germination under salt marsh environment is the key that grows of halophytes and sensitive stage with emerging, and salt stress causes its percentage of seedgermination to decline.
The present invention is based on Halophyte Resources to develop and cultivation practices, sum up wild naringi crenulata saline land nursery key technology, to providing basic data for promotion naringi crenulata industrialization cultivation and deep development.
Summary of the invention
The object of the invention is to provide a kind of arid region saline-alkali soil limonium gmeliniiKuntze seedling breeding method, the method is opened parallel to shallow ridges in saline land, furrow are done by certain area, first by furrow flood irrigation, furrow irrigation drip washing salinity, seedbed is made to be in less salt state, and then simulation seedling naturally-occurring condition, the successful planting of limonium gmeliniiKuntze seedling from seed is ensured with " furrow irrigation+overboard sow ".The method of the invention be arid region saline-alkali soil greening, beautify and have accumulated technological reserve.The method is by technical combinations such as structure furrow mima type microrelief, furrow flood irrigation, furrow irrigation, and suitable soil environment is created in the planting for limonium gmeliniiKuntze, to realize its large-scale planting.Method of the present invention, respectively in little Guai township, Kelamayi, Chinese Academy of Sciences Desert of Fukang ecology station, Tan Huilin base, Kelamayi carried out planting experiment, test shows that limonium gmeliniiKuntze planting percent is all more than 70%, for arid region saline-alkali soil greening, beautify and have accumulated technological reserve.
A kind of arid region saline-alkali soil limonium gmeliniiKuntze seedling breeding method of the present invention, follows these steps to carry out:
A, selection of land and whole:
Select the smooth plot of 0-20cm soil layer salt content 1.5-2.5%, plow harrow ensures that sowing soil is in small, broken bits smooth;
B, structure furrow landform:
By parallel to ditching, ridging, bottom of trench spacing 0.6m, dark 0.2-0.3m, ridge face width 0.2-0.3m, slope, floating ridge, structure furrow landform, with long 5.0m, wide 3.0m does furrow, and the furrow surrounding low bank of earth between fields is higher than face, ridge in furrow;
C, irrigation water management:
The water treatment of sowing advance wardrobe, head water open fire is poured water for the 2nd time after disappearance 3-5 days completely, trickle irrigation in after planting interval 2-3 days, the water yield covers sowing line for degree with the water surface, maintain ground moistening in ditch, after naringi crenulata emerges aobvious row, regularly pour water and keep ground moistening in ditch;
D, sowing:
After pouring water for 2nd time, in good time " overboard sow " is sowed.
Flood irrigation process in head hydromining furrow in step c, in furrow, water will cover face, ridge.
After in steps d, sowing selection is poured water at the 2nd time, in ditch, open fire disappears to about 1/2 place on slope, ridge, broadcasts sowing along waterline.
A kind of arid region saline-alkali soil limonium gmeliniiKuntze seedling breeding method of the present invention, the feature of the method is:
The flood irrigation of reform traditional and the sowing of border irrigation seedbed formula, by the combination of ditch ridge landform and furrow flood irrigation, furrow irrigation, effectively control soil salt to the suppression of seed germination and seedling distribution at random.Furrow flood irrigation can alleviate suppression to seed germination by drip washing surface soil salinity; Furrow irrigation can reduce irrigation water consumption, and the face, ridge of furrow mima type microrelief can carry the soil salt assembled by evaporation; In accordance with limonium gmeliniiKuntze seedling pests occurrence rule, adopt " furrow irrigation+overboard sow " to ensure seedling planting success.Adopt method of the present invention, limonium gmeliniiKuntze can be realized in the successful planting on the ground of severe saline soil.
