Abstract
The invention relates to a controlled irrigation inducing method for root growth of a perennially deep rooting plant. The method provided by the invention is finished by the following steps of configuring a subdistrict, configuring water-blocking tapes, configuring a controlled irrigation system and configuring a soil water observing system. Through utilizing the method provided by the invention to carry out the controlled irrigation on Alhagi plants, the result shows that: under the drought condition, the growth depth of roots of an annual seedling of the Alhagi is the maximum and the depth can reach 200 cm at the end of the growth season; under the suitable irrigation condition, the growth depth of the roots of the annual seedling of the Alhagi reaches 120 cm at the end of the growth season and few new divided plants are generated in the second year of growing; under the sufficient irrigation condition, the growth depth of the roots of the annual seedling of the Alhagi is the minimum and the depth is only 80 cm in the growing season; and a lot of new divided plants and a blooming phenomenon are generated in the second year of growing. The method provided by the invention is applied to the root growth of the Alhagi of Qira National Station on the south rim of the Tarim Basin and provides technical supports on regulation and control of the root growth of the perennially deep rooting plant in drought regions and an analysis of a settling process of roots, so that the invention provides a new way for repairing deep rooting plants under environmental conditions of the drought regions.
Description
Technical field
The present invention relates to a kind of control at the perennial deep rooting plant root growth of arid biogeographic zone and irrigate abductive approach, the promotion and application of the method will provide technical guarantee for the regulation and control of arid biogeographic zone deep rooting plant root growth and the processor establishment analysis of root system, thereby provide new approach for the reparation of deep rooting plant under the arid biogeographic zone environmental condition.
Background technology
The root system of plant ecological study is the Focal point and difficult point of current ecological study, particularly the ecological processes research of the dark root system plant of arid biogeographic zone more and more is subject to numerous scholars' extensive concern.But because the restriction of research means and technical method, the root growth in the research of root system ecological processes dynamically observation is " bottleneck " in the present ecological study with the analysis of root system processor establishment.Therefore, the observation procedure of exploring and set up the Root-development that can generally use (eremophytes that particularly can be applicable to be grown in arid biogeographic zone) seems most important.
Camel thorn is perennial dark root herbaceous plant, and the distribution of certain area is arranged at the Oasis-desert Ecotone of south, Tarim Basin edge.Camel thorn is the main vegetation of checking winds and fixing drifting sand; they not only have the characteristics of strong adaptability, drought-resistant, Salt And Alkali Tolerance; and be the important component part of oasis protection system; it is the important ecological protective screen of improving the ecological environment, protect farming and animal husbandry to produce; camel thorn is again a kind of important plant resources simultaneously, occupies certain status in livestock breeding is produced, has the irreplaceable effect of artificial measures.But for a long time, owing to artificially utilize unreasonably and livestock destruction, the nearly peripheral camel thorn vegetation in Nan Yuan oasis, Tarim Basin is seriously damaged.Accelerate the reparation of camel thorn vegetation, good feed and pasture both can be provided, promote animal husbandry development, increase masses' income, will make up safety curtain for oasis farmland again.This technological achievement will provide hands-on approach and technological approaches for the reparation of south, Tarim Basin edge camel thorn vegetation.Therefore, has important using value.
Edge zone, south, Tarim Basin is Extreme Dry/drought-hit area and the place threatened by wind and sand of Chinese Famous, and sandstorm is frequent, annual mean wind speed 1.9m/s, because the granularmetric composition of sand material is partially thin, under the wind friction velocity greater than 4m/s, can play sand, annual wind speed greater than the number of days of 4m/s more than 90 days.Spring, summer much wind weather, annual strong wind 3-9 time more than eight grades.Mean annual precipitation 35.1mm, a year evaporation discharge reaches 2595.3mm, and aridity is 20.8.Under such extreme environmental conditions, it is the major issue that merits attention that the habitat of camel thorn plants root system adapts to feature (particularly Root growth process), and is the key content of present technique exploration to the method for Root-development observation with approach.
Camel thorn is a kind of deep rooting plant, and some its root system of zone of southern edge can reach about 15 meters deeply in the Tarim Basin.For for deep rooting plant and clone plant the camel thorn, it is very difficult inducing and stimulate its root growth by surface irrigation under natural environmental condition.Therefore the control irrigation inductive technology that must inquire into a kind of suitable deep rooting plant growth characteristic could realize.We irrigate inductive technology around these basic ideas to the control of deep rooting plant root growth just and explore.The characteristic of present technique is: the different times in the camel thorn growth is regulated and control the root growth of camel thorn plants by the method for Artificial Control irrigation time and irrigation volume in good time, be grown to the master, be grown to main, also in good time generation plant division with horizontal branch afterwards with vertical root in early days to reach camel thorn, realize enlarging the purpose of population, thereby accelerate the process of growth of settling down of camel thorn plants.
Summary of the invention
The object of the invention is, under the arid biogeographic zone environmental condition, provide a kind of control of perennial deep rooting plant root growth to irrigate abductive approach, the method is to be finished by residential quarter setting, waterstop setting, control irrigation system setting and soil moisture observation system setting steps, after by the method for the invention camel thorn plants being controlled irrigation, its result shows: arid treatment conditions: the growth degree of depth of the annual seedlings root of camel thorn is maximum, can reach 200cm at the growth end of the season; The appropriateness irrigation conditions: the root growth degree of depth of the annual seedling of camel thorn reaches 120cm at the growth end of the season, in a small amount of new plant division of Second Year generation of growth; Abundant irrigation conditions: the root growth degree of depth of the annual seedling of camel thorn is minimum, season only has 80cm in growth, produces in a large number new plant division and Flowering Phenomenons at the Second Year of growing.The method is used in the irrigation regulation and control of the camel thorn root growth that Nan Yuan Qira, Tarim Basin country stands, to provide technical guarantee for the regulation and control of arid biogeographic zone deep rooting plant root growth and the processor establishment analysis of root system, thereby provide new approach for the reparation of deep rooting plant under the arid biogeographic zone environmental condition.
