Description

Arid and semi-arid area forest collection rain anti drought cultivation method
Technical field
The invention belongs to Forestry Engineering technical field, is related to the Tree Drought Resistance cultivation that a kind of arid and semi-arid area collects the rain moisture Method.
Background technology
The Arid&semi-arid area in China accounts for the 2/3 of territory total area, and drought and water shortage not only has a strong impact on China Agricultural development, and also contribute to the development of ecological environment and forestry.Rational polywater soil moisture conservation technology is to improve woodland market effect The key link of rate.Water saving has been the inevitable choice of national sustainable development, therefore, during Society has become The current or even later long-term target of state.China just explored always in the Agriculture developing history of thousands of years using water and soil conservation as Main rainwater shortage technology, the microhabitat ecosystem how being applied to using technology of water catchment under crop supplementary condition, solution Certainly well between " rainfall-crop-environment " unified relationship Optimal regulation and control, be to realize the key that rainwater efficiently utilizes.Nearly more than ten Nian Lai, China obtain the technologies such as many collection rain achievements, particularly the Northwest's collection rain are drunk water, collection rain is irrigated in terms of rainwater utilization Important function is played.At present in Forestry Engineering, forest land collection rain measure has the conventional arts such as fish-scale pit, horizontal ditch, contour bench Measure.There is these technical measures preferably collection rain to infiltrate effect, and still, generally existing effective time is short and evaporation water loss is serious The problem of.Therefore, collection rain enters the pursuit for blending that the function measure that soil moisture conservation is provided simultaneously with is always vast forestry technical personnel on the spot Target.For example patent of invention CN103461070A discloses a kind of arid growing area hillside fields collection rain drough-relief method and structure, the party Method is to be provided with the field in arid plantation slope area with slope aspect identical alley, is spread in the furrow between alley and two alleys Mulch film, and collection rain rill is opened up at the bottom of slope in field, Ji Yukeng is opened up in one end of collection rain rill, while in horizontal plane less than collection rain Multiple Sheng rain bags are set at hole, the one end for containing rain bag is connected by plastic flexible pipe with Ji Yukeng, and the other end is provided with controllable water discharging hole.Again Such as patent of invention CN103556672A, CN102524014B, CN102246628B, relate to cover the collection including mulch film The rain collecting layer face of rain sheet material is come the technology that collects the rain moisture.For such technology for peasant, cost is of a relatively high, and operating procedure is numerous It is more, it is time consuming;The gathering surface of forest individual is small, and rain water distribution is uneven.
The content of the invention
The present invention in view of the deficienciess of the prior art, provide it is a kind of suitable for arid and semi-arid area it is easy to operate, without dirt The Tree Drought Resistance cultural method that dye, low cost, high efficiency, long timeliness collect the rain moisture.
To achieve these goals, the present invention is achieved using following technical scheme:
Arid and semi-arid area forest collection rain anti drought cultivation method, comprises the following steps:
(1), in the Forest-tree culture ground that soil property is sandy soil or loam, suitable tree goes, collects rain rill, furrow width along the horizontal excavation of contour 2m, planting tree row flatten the two sides of ditch on the center line of ditch, and in " V " type, the side grade of ditch is 10 °~45 °, Ditch is divided into Bamboo-shaped segmentation ditch with soil by the length of spacing in the rows, at every Duan Gou areas 1~1.5m of the separation ridge closer to the distance, excavated One 0.5~1m of diameter, depth 10cm circular planting hole, one plant of the trees of plant per cave;
(2) to select thickness be 0.008~0.01mm, the anti-aging mulch film that width is 1.2~1.5m, and double films docking longitudinal direction is covered Lid Bamboo-shaped " V " type collection rain rill region, joint are suppressed with soil and suppress mulch film with soil on tight, the horizontal Bamboo-shaped separation ridge, The infiltration aperture that 1~3 diameter is 1cm is being made a call at plant pit on mulch film;
Before rainfall, moisturizing irrigate when can in plant pit dressing fertilizer.
Described anti-aging mulch film is one kind in colourless transparent film, coloured mulch film, the preferably anti-aging mulch film of black.
Described Tree Drought Resistance cultural method, all kinds of commodity trees on the hillside fields, level land suitable for arid biogeographic zone semiarid region Building well is cultivated and urban landscaping trees, rare rare trees, the big seedling cultivation of Woody flower, is also applied for ecological forest Anti-drought afforestation, the cultivation of the earsh at the arid biogeographic zone economic forest building well of being particularly suitable for use in initial stage.Described Tree Drought Resistance cultivation side Method more carries out man-computer cooperation implementation using pure artificial implementation using rotary cultivator, ditcher, laminating machine.
Compared with prior art, beneficial effects of the present invention:
(1) the present invention can effectively improve precipitation utilization ratio, soil moisture content;Greatly improve forest planting survival rate, protect Deposit rate, increment;Be obviously prolonged the tree growth phase, accelerate forest growing process, shorten nursery stock be bred as out the garden time limit, can promote through Ji forest formed ahead of time high yield it is tree-like, into the best fruiting period, orchard per unit area yield improves more than 30%;Irrigation frequency is greatly decreased, irrigates Water, effectively reduce production cost.
(2) " V " type film surface structure water catchment efficiency is high, while the accumulated temperature of soil, the area that heats of individual plant plant also increase under mulch film Add, promote the development of root system;Bamboo knot shaped structure ensures that forest individual can obtain evenly distributed rainwater, prevents from forming earth's surface Runoff, effectively conserve water and soil;Can be that individual plants have built wide 2m, be long equal to spacing in the rows (m), catchment area (m2)=spacing in the rows (m) × 2 (m), forest is set to obtain larger phototrophy space;Average annual individual plant plant theory afflux total amount (m3)=spacing in the rows (m) × 2 (m) the average annual rainfall (m) in × locality.
(3) earth volume is small, and labour cost is cheap, and one time overlay film can at least be used continuously 2 to 3 years.
