Description
Technical field
The invention belongs to the Forestry Engineering technical field, relate to mountain region, hillside fields, orchard, hills, forest land collection rain utilization technology, be specifically related to the polywater method for preserving soil moisture that forest land, a kind of hillside collection rain infiltrates.
Background technology
China is a country that lack of water is serious.The arid and semi-arid area accounts for 2/3 of the gross area, and drought and water shortage has not only had a strong impact on the agricultural development of China, and affects the development of ecotope and forestry.China is the country on mountain more than, mountain region, hillside fields area be the Plain plough more than 2 times, and the mountain region, rainwater savings in hillside fields utilizes is the important channel of improving forest land production efficiency.Reasonably hillside fields polywater soil moisture conservation technology is to improve the key link of forest land moisture efficient; For the nervous country of a water resource; Water saving has been the inevitable choice of national sustainable development, and therefore, conservation-minded society's construction has become the current even later long-term target of China.Water and soil conservation is just being explored always by China in agricultural development history in several thousand be main rainwater savings utilization technology; There are a lot of collection rain achievements in China aspect rainwater utilization in recent ten years, and particularly technology such as the Northwest's collection rain drinking-water, the irrigation of collection rain has been brought into play important function.
In Forestry Engineering, the collection rain measure in the hillside jujube woods also has conventional art measures such as fish dace hole, horizontal ditch, horizontal rank at present.These technical measures have and collect rain preferably and infiltrate effect, still, have the short and serious problem of evaporation water loss effective time.Therefore, to go into to blend the function measure that soil moisture conservation possesses simultaneously on the spot be pursuing one's goal of vast forestry technology personnel to collection rain always.
Summary of the invention
The polywater method for preserving soil moisture that the object of the present invention is to provide forest land, a kind of hillside collection rain to infiltrate; This method can utilize collection rain to increase the soil moisture reserves in artificial afforestration; The gardens that mountain region, hillside fields are planted collect the whole ground of rain soil moisture conservation, and have simple to operate, easy construction, cheap, persistence strong, liquid manure utilizes characteristics of high efficiency.
Another object of the present invention is the polywater method for preserving soil moisture that provides a kind of forest land, hillside collection rain that is used for Chinese jujube garden to infiltrate.
In order to achieve the above object, the present invention takes following technical solution to be achieved.
(1) the collection rain polywater method for preserving soil moisture that infiltrates in forest land, a kind of hillside is characterized in that, comprises the following steps: at first, between two strains tree, along a polywater soil moisture conservation of domatic horizontal excavation ditch; Then, in the good polywater soil moisture conservation ditch of excavation, insert the organic plant material, and compacting.
A more step of technique scheme improves and is, utilizes the machine vegetable material to mix according to the arboreal growth phase and topdresses.
The characteristics of technique scheme are:
Said organic plant material comprises difficult humus material, and difficult humus material is a branch, and its average length is 1-5cm.
Said organic plant material comprises perishable vegetable material, and perishable vegetable material is leaf and/or comminuted plants stalk, and said perishable vegetable material weight content is less than 30%.
Said organic plant material comprises organic manure, and the weight content of organic manure is less than 15%.
The width of said polywater soil moisture conservation ditch is 30-40cm, degree of depth 30-40cm.
(2) the collection rain polywater method for preserving soil moisture that infiltrates in forest land, a kind of hillside is used for Chinese jujube garden, it is characterized in that, comprises the following steps: at first, between two strains tree, along a polywater soil moisture conservation of domatic horizontal excavation ditch; Then, in the good polywater soil moisture conservation ditch of excavation, insert the organic plant material, and compacting; Said organic plant material comprises difficult humus material, perishable vegetable material, organic manure; Said difficult humus material is a branch, and its average length is 1-5cm; Said perishable vegetable material is leaf and/or comminuted plants stalk, and its weight content is less than 30%; Said machine by weight of fertilizer content is less than 15%.
A more step of technique scheme improves and is, and utilize the machine vegetable material to mix according to the arboreal growth phase and topdress, wherein, and leaf renewal fertilising 1 time, the fertilizer that every strain jujube tree is used is: urea 1.0kg～2.0kg; Superphosphate 2.0kg～4.0kg, potassium sulphate 0.7kg～1.0kg; Apply fertilizer flowering stage 2 times, the fertilizer that each every strain tree is used is: urea 0.1kg～0.2kg, potassium sulphate 0.1kg～0.2kg; Fruiting period fertilising 2 times, urea 0.4kg～0.5kg is used in each every strain.
The characteristics of technique scheme are that the width of said polywater soil moisture conservation ditch is 30-40cm, degree of depth 30-40cm, and its bank is apart from trunk 30-50cm.
Among the present invention, the organic plant material mainly plays good permeable effect and rainwater and infiltrates the back and significantly reduced the evaporation loss of moisture by the covering effect; Compacting organic plant material in polywater soil moisture conservation ditch is passed and depression to prevent filler in time, forms bigger pit.
The present invention combines the domatic rainfall in mountain region down to produce the characteristics of runoff along the slope; To have water penetration strong with the organic plant material; Suppress significantly effect of evaporation, with polywater preserve soil moisture ditch with infiltrate soil moisture conservation material (organic plant material) and well combine, the most effectively the rainwash segmentation is retained; Make rainwater can be good at herein saving and good preservation, supply with the arboreal growth demand slowly.
Leaf or comminuted plants stalk itself are exactly a kind of material that nutrient is provided, and can also mix with fertilizer at this simultaneously and use, because polywater soil moisture conservation ditch has moisture preferably; Fertilizer can be brought into play the effect of water and fertilizer coupling herein; Compare with traditional fertilizing method, it is easy to operate to apply fertilizer, and the fertilising effect improves 2-3 doubly; Fertilizer is slowly discharged, improve fertilizer efficiency availability 26%; Simultaneously, also conveniently topdress.
The present invention is not only applicable to Chinese jujube garden, helps the high grade producing and adaptation mountain region, jujube tree garden, hillside fields change of soil fertility of jujube tree; Also be applicable to simultaneously other mountain regions, gardens, hillside fields.The present invention has crucial practical significance and practical value to promotion high-efficiency water-saving drip irrigation technique, development China commodity trees, the particularly fruit of mountain area areas of serious industry and forestry.
