Description
Technical field
The present invention relates to desertification district cultivation method, be specially the ecological protection cultivation method of a kind of district asparagus of desertifying.
Background technology
Soil desertification refers to that good soil or available soil become the process even becoming desert containing husky a lot of soil or soil.Soil desertification main process is wind erosion and wind deposit process.In surrounding area, desert, due to vegetation deterioration or meadow heavy grazing or open up wasteland as farmland, soil becomes dry because of dehydration, grogs disperses, and is lost by wind, and fine particle content reduces.And after wind-force or the location of weakening, dust storm particle is piled up in upper soll layer gradually and makes soil desertification.Therefore, soil desertification comprises the wind erosion process of grassland soil and the aeolian sediments process in location far away.
China endangers one of the most serious country by soil desertification in the world.At present, national desertification area reaches more than 170 ten thousand square kilometres, accounts for about 18% of area.And the expansion rate of soil desertification is fast, developing state is severe, and soil desertification causes the slump of disastrous proportions of productivity of land, exacerbates the deterioration of ecotope, becomes current great environmental and social concern.
At present, main following 2 kinds of methods of having checked winds and fixed drifting sand: (1) is fixed the sand by engineering measure, and the most frequently used is that mechanical sand barrier fixes the sand.Mechanical sand barrier as tackling quicksand leading measure or as plant be difficult to grow heavy sand damage district independently Sand-fixing Measures be widely used in vast husky district of China.But because of the difference of the material of mechanical sand barrier, specification, kind, in the investigation and application of mechanical sand barrier, also there is obvious problem.Wheat straw sand-protecting barrier as commonplace application in practice is perishable to be buried with sand, branch vertical sand barrier is then subject to wind erosion and lodges, thus make sand-protecting barrier ineffective, having to carry out reseting of sand-protecting barrier to continue tackling quicksand, causing the waste of the resource such as increase and human and material resources of cost.Therefore, there is the problem of the permanent and high expensive of control efficiency in mechanical sand barrier.(2) fixed the sand by biological control measure, mainly plant shelter belt.Vegetation can form protection by number of ways to earth's surface; especially the deserta of desert edge has important function to prevent desertification expansion; tackling quicksand effective measures the most; but its construction period is long; performance benefit is slow; can not meet the requirement that highway controls rapidly sand damage, thus normal and mechanical sand barrier uses jointly.Wherein, the seeds of the desertifications such as plantation Populus Euphratica, red building, sacsaoul, elm, pine tree, caragana microphylla, sea-buckthorn are more common sand consolidation with biologic methods, but the required cycle is long, deficiency in economic performance.
Summary of the invention
In order to solve existing machinery sand-protecting barrier and sand consolidation with biologic, the present invention exists that the cycle is long, cost is high, the problem of deficiency in economic performance, provide the ecological protection cultivation method of a kind of district asparagus of desertifying.
The present invention adopts following technical scheme to realize: the ecological protection cultivation method of desertification district asparagus, adopts following steps to realize: a, select purple passion, champion, well ridge 701 kind to carry out plug media nursery; B, carry out ditching field planting, the ditching degree of depth is 20-25cm, does not apply fertilizer, plantation density 800-1000 plant/acre, field planting degree of depth 15-20cm; C, field planting were respectively watered once the same day, the 3rd day, the 7th day, and stayed little grass to keep ground coverage rate; D, stay 4-6 female stem when gathering all the time.
Ditching depth; choosing of plantation density, the degree of depth is all that test by a large amount of draws; choosing of this scope; effect of checking winds and fixing drifting sand is better; cost is also relatively low; be the suitable ditch depth of ecological protection type asparagus cultivation, the field planting degree of depth and density range, overcome that the cycle that existing machinery sand-protecting barrier and sand consolidation with biologic exist is long, cost is high, the problem of deficiency in economic performance.
The present invention plays and can play good sand break and fixation function, can reduce wind speed 18-22%, and resistance sand act as 0.6-0.7.Compared with plantation shrub species, can greatly shorten the cycle of checking winds and fixing drifting sand, and good economic benefit can be produced, increase local farmers income.

In specific implementation process, the selection of asparagus kind is the result of 8 varietal yield tests.Variety comparative test establishes 8 kinds (purple passion, Da Baoli, holy knight, well ridge 701, Glan moral, champion, Grace, Feng Teli), repeats for 3 times; Line-spacing 1.2m, spacing in the rows 25cm; Zone leader 10m, wide 1.2m, plot area 12 ㎡, the gross area 288 ㎡ is taken up an area in test.The result of the test of 3 years shows, the strong stress resistance of purple passion, champion, these 3 asparagus kinds of well ridge 701, product are of fine quality, output is high, is all suitable for producing as ecological protection type asparagus in desertification district.
Asparagus seedling growth stage needs to keep rational soil temperature and humidity, but desertification district water retention is poor, fertility is low, difference variation is comparatively large, is not suitable for asparagus nursery.Therefore, seedling medium is adopted to be very important.Conventional asparagus seedling-cultivating method easily hinders root when lifting, and after field planting, seedling-slowing stage is long, is unfavorable for growing of asparagus.And adopt point disk seedling growing to compare science.
In seedling raising process, asparagus seeds temperature scalds method for soaking seed process, and 25-30 DEG C of water seed soaking 48h, every day washes seed 2 times with clear water.
Sowing after the seed of 25-28 DEG C of constant temperature vernalization 3-5d, 10-30% shows money or valuables one carries unintentionally.
Matrix is loaded cave dish, every bunch planting kind 1 seed, above covers matrix 1-1.5cm.According to actual conditions, pour water under adopting cave dish or the upper water spray of cave dish.
Before emerging, daytime keeps 25-30 DEG C, and night keeps 15-18 DEG C; Soil humidity keeps the 70-80% of matrix maximum water-holding capacity.
After emerging, day temperature keeps 25-28 DEG C, and nocturnal temperature keeps more than 15 DEG C, and soil humidity is advisable with " see dry see wet ".
When there is the 2nd terrestrial stem, mend and execute foliage fertilizer, every about 2 weeks once, 5-7 days before field planting, and what adopt protecting field nursery should strengthen day and night temperature, progressively adapts to ambient temperature condition.
General production asparagus field planting ditch depth 30-40cm, and execute a large amount of fertilizers and make base manure.In the present invention, ecological protection type asparagus cultivation method adopts the ditch depth of 20-25cm, does not apply fertilizer, and is to stress ecological benefits, investment reduction cost.
General production is 2000-2800 plant/acre by the plantation density of asparagus.In ecological protection type asparagus cultivation process, mainly consider to check winds and fix drifting sand effect and cost of investment, be auxiliary, checking winds and fixing drifting sand under effect same case with economic benefit, least density investment is the most reasonable at least.From checking winds and fixing drifting sand and cost of investment consideration, the density of 800-1000 plant/acre, effect of checking winds and fixing drifting sand is better, and cost is also relatively low, is the Suitable Density scope of ecological protection type asparagus cultivation.
The general field planting degree of depth is 10-15cm, considers in ecological protection type asparagus cultivation process, does not substantially water after surviving; in the present invention; field planting depth ratio conventional depth adds 5cm, and this just can make full use of the moisture of deep soil, and soil temperature change is less than the soil temperature change of 0-10cm.Adopt these 2 kinds of degree of depth of 10-15cm and 15-20cm to carry out field planting, do not rewater after surviving.Field planting 60d " Invest, Then Investigate ", the asparagus plant height of the 15-20cm field planting degree of depth is 37cm, and significantly increase 5cm than 10-15cm field planting degree of depth asparagus plant height, strain width is corresponding increase also.
Field planting same day, field planting 3 days, field planting are respectively watered once for 7 days, do not rewater later; But, in case of continuous 30d does not have the situation of precipitation to water.The poor water retention property of desertification ground soil, in order to ensure the high-servival rate of bamboo shoot seedling, waters once more between the field planting same day and 7 days.
The large grass of field planting First Year removing, stays little grass to keep ground coverage rate; Second Year optionally can be no-tillage.In ecological protection type asparagus cultivation, do not cultivate intensely, also do not interplant, so First Year needs to leave little grass and keeps ground coverage rate, and the evaporation reducing surface water is scattered and disappeared.But, large grass be removed, in order to avoid large grass and asparagus competition for nutrients and moisture.Second Year, asparagus starts quick growth, as long as the growth of weeds does not produce nutrient and moisture keen competition with asparagus can retain weeds, realizes the object of asparagus and the common protecting ecology of weeds.
The mode of " Liu-Cai-Liu-Cai " is adopted to gather.In earlier stage (the 4-6 month), stay 4-6 female stem, later tender stem is gathered and is done commodity bamboo shoot; In mid-term (the 7-8 month), stay 4-6 female stem, later tender stem is gathered.Different regions suitably can adjust according to weather conditions.
This picking methods takes full advantage of local weather conditions, reaches the object of checking winds and fixing drifting sand, also can obtain certain economic benefit.General antecedent precipitation is less, and when not watering, Quality of asparagus is poor, now, protects retain the stubble accumulation nutrient component, for checking winds and fixing drifting sand; After June, precipitation increases, and now adopts bamboo shoot, and Quality of asparagus is excellent, commodity good, high efficiency.After July, 4-6 female stem is stayed in every strain, and for checking winds and fixing drifting sand, the tender stem later grown again is all gathered.Like this, while checking winds and fixing drifting sand, the mu stem number in unit are can be reduced on the one hand, reduce the generation of the diseases such as stem wilt, on the other hand, because Quality of asparagus is excellent, later stage price is high, significantly can increase economic benefit.
