By adopting the invention, soils can be built in the bare purple rock sloping fields, and orchard is built; the purpose of recycling and highly-efficient utilization of the lands difficult to use in purple rock areas is realized.
Description
Technical field
The present invention relates to the naked rock of a kind of purple rock hillside fields soil building method, especially relate to the method that the naked rock of a kind of purple rock hillside fields soil building is built the orchard.
Background technology
The purple soil mountain and hill is China south and one of main land type in southwest, and wherein Sichuan Basin purple rock distributes extensively, and area is maximum.Purple soil calcic and phosphorus, potassium are than horn of plenty, and parent rock is prone to smash weathering.In the open weathering speed test after Soil Dept. of Chengdu Branch, Chinese Academy of Sciences once made purple rock and smashes, the result shows, the fastest rock of weathering in the purple rock can be weathered into soil in 1 year after smashing.Therefore, the purple soil renovation is fast, is the exclusive valuable land resources of China.Particularly hillock, the purple soil hills gradient is little, and general dried up source is nearer, is convenient to irrigate, the comparatively suitable woods fruit of developing the economy.
But for a long time, purple soil massif district forest cover is seriously damaged; Cause vegetation sparse, soil layer is shallow mostly, even parent rock is exposed; Severe water and soil erosion, and seasonal weather high temperature and drought is arranged, forestation planting grass is difficulty very; Especially the most typical with purple mound hillock, make hillside ground, mound, most of purples soil become the naked rock of purple rock hillside fields.
The rural area, Sichuan adopts the half-naked slope of revealing of blasting method exploitation purple rock to make the purple rock fragmentation be weathered into the soil, plant crops and trees (Li Zhongming, Chinese purple soil, the first volume, 1991).Because the domatic type gradient of selecting is bigger, though or the gradient little, the parent rock of explosion is the purple sandstone, difficulty is weathered into soil, the mineral nutrient content is abundant, or technology do not match, aspect work as north wind, thereby effect is not remarkable, this method application study ten minutes is limited.
The Liu Tang township, Hengyang County of Hengyang Basin in the seventies in 20th century, adopts the explosion thin purple mound hillside ground of moat method exploitation soil layer of raising, and plants Chinese tallow tree, and survival rate is higher, but economic flow rate is very low; Tan Zi mountain area, Hengnan County well village peasant adopts the explosion moat method of raising, the plantation citrus that cuts into a mountain in the domatic naked rock of purple sandstone hillock mixed type hillside fields, and death rate reaches 100% (Xie Tingsheng, 1983).Over nearly 10 years, raising with explosion at Hengyang Basin, moat method exploitation purple rock is half-naked to be revealed drought-resistant firewood forest seeds and herbaceous plant such as hillside fields plantation giantreed, perverse Chinese scholartree, China tree and obtains certain effect (Wang Chenglin, 2003).
But reveal purple rock hillside fields plantation economic forest and all successes of fruit tree with the raise semi-nudity of moat method exploitation soil layer thin (soil thickness is below 10cm) of explosion, especially develop the naked Yan Po of purple rock hillside fields and plant economic fruit and do not see successfully.
Summary of the invention
The objective of the invention is to overcome the above-mentioned defective that prior art exists; A kind of purple rock hillside fields that both is fit to naked dew is provided; The method that the naked rock of the purple rock hillside fields soil building in the purple rock hillside fields that suitable again soil layer is thin is built the orchard is utilized the soil to make full use of the uncultivated in a large number difficulties of purple soil massif, develops distinctive agricultural undertakings; Alleviate the people ground contradiction of purple soil area, revitalize local economy.
The objective of the invention is to realize that through following technical scheme it may further comprise the steps: (1) on slope, the southeast, purple boss hillock, selects the gradient less than 15 ° the naked rock of purple sand shale alternating layers or ground, the naked rock of purple shale gentle slope, as the object of orchard soil building; (2), delimit detonating fuse and borehole point along contour in selected soil building hillside fields; (3) spring, carry out 2 secondary clearing directional blastings, first collaring makes direction heap rubble direction inclination on the borehole, so that land the directed location of rubble; A glance 2 big guns are blown out fried broken top layer parent rock for the 1st time, the fried broken bottom parent rock of the 2nd big gun; Carry out thin layer and stack (promptly only pushing away 2 layers of gravel), form trench, wide 1.1-1.3m on the trench (preferred 1.2 m); Following wide 0.9-1.1m (preferred 1.0 m) 1m; Dark 0.9-1.1m (preferred 1.0 m), the long 6-20m of ditch links to each other with the drain ditch; (4), stirred thin heap gravel 1-2 time, and promoted that gravel was weathered into soil in every month at autumn in summer high temperature season; (5) autumn Mo in next year is with the gravel of detrition and half waste, waste backfill, first backfill rubble and coarse granule waste, back backfill fine grained waste; And insert organic manure; (6) high level ladder soil such as build, to the gradient domatic less than 10 °, 2 trenches of explosion are 10-15 ° domatic to the gradient, and 1 trench of explosion builds up horizontal ladder soil then respectively; (7) by standard soil moved in to improve the original fertilising, to 2mm particle ratio 23.5% below≤the table soil of 50cm and native at the middle and upper levels, the visitor goes into ten thousand kilograms/hectare of (promptly mixing) fine grained soil 4.0-5.0, and ten thousand kilograms/hectare of organic fertilizer 2.0-2.5; (8) plant fruit tree after, the topsoil of turning over quickens waste Cheng Tuhua mud at the middle and upper levels; (9) plant crop between, culture fertility is planted watermelon, legume in the period of 2, and fertilizing soil, a kind watermelon, per 667 ㎡ are executed and done 1500 kilograms of animal dung 1000 ﹣.
In said (1) step, the said gradient is less than 15 ° naked rock of purple sand shale alternating layers or ground, the naked rock of purple shale gentle slope, be the domatic ground of linear pattern, stepped ramp type ramp face ground, matrix slope the bottom surface or the sloping end face of convex ground.
In said (2) step, distance between adjacent two detonating fuses and the distance between the adjacent borehole are 4m.
In said (3) step, after borehole was accomplished fluently, the handle that spreads straw of the ground around the borehole in the 4m scope was pressed trunk again, strengthening explosive to the horizontal force of explosion of rock, and prevented that rubble from disorderly flying to hurt sb.'s feelings.

In said (7) step, the earth that the visitor goes into is acidity and the sticking heavy soil of quality; Said acidity and quality are glued the heavy preferred four discipline laterite red soil of soil, plate shale red soil or limestone red soil, or open grave mud and/or ditch mud, or the paddy soil that is become by these soil developments, and four discipline laterite red soil are first-selected earth.
Said (9) step is when planting watermelon in the period of the orchard 2, at the straw of table earth mulch one bed thickness 1-3cm; Between when planting other erect type annual crops, also broadcast sowing red clover or white Russian red clover section herbage.
Further improved preferred version:
After raising fruit trees, show native the covering: available straw covers table soil, or plants red clover, white three foliage cover tables soil, to reduce table soil temperature degree, reduces soil water evaporation, the saving irrigation water.The straw cladding thickness can be 3-7cm.
Also should plant the Chinese alpine rush bank protection in the outside, the terraced ridge (claiming terraced wall again), from the terraced ridge outer lower portion to top the capable Chinese alpine rush of kind 2-4, form plant hedge bank protection, with further reduction table soil temperature degree, reduce soil water evaporation, save irrigation water.The preferred 40cm of said Chinese alpine rush line-spacing, spacing in the rows 20cm.
The present invention is owing to select to be positioned at southeast aspect; The gradient is built the object in orchard as soil building on purple sand shale alternating layers below 15 ° and ground, the naked rock of purple shale gentle slope; And take directional blasting, Bao Dui (promptly piling 2 layers of gravel), stir promotion purple rock rubble such as rubble and be weathered into soil and repair horizontal ladder soil, soil moved in to improve the original fertilising, straw and cover measures such as drought resisting, intercropping fertilizing soil, plant hedge bank protection; Produce soil with making the naked rock of purple rock gentle slope; Build up the orchard of fruit such as cultivation citrus, grape, pears, peach, Lee Blang; Realization purple rock area difficulty utilizes land resourcesization and efficient utilization the (per hectare can be produced ten thousand hectares of fruit 3-6,4.5 ten thousand yuan of the increase output values) to help changing local soil situations uncultivated in a large number and backward in economy, rural poverty.
Embodiment
Below in conjunction with embodiment the present invention is described further.
1. select ground
(1) selection of aspect.Research shows that province purple soil massif districts such as Hunan, Jiangxi, Zhejiang are in the big freezing period in year January in December, 2007 to 2008; The minimum air temperature reaches-10 ℃, has surpassed patient-7 ℃ of oranges and tangerines, the level land of flat area and hills area; Oranges and tangerines garden extremely tree rate reaches 10%, and the hillside fields orangery of hills area extremely tree rate is about 10%, and the equal frostbite not of the trunk of the orangery tangerine of 90% southeast aspect; Have only the part branch to receive slight frostbite, still normally yield positive results then.In the general time, slope, southeast percentage of fertile fruit is apparently higher than the slope, northwest.The survey showed that to the orangery percentage of fertile fruit for the oranges and tangerines garden that Tan Zi mountain, Hengnan County, Hunan town Song Qiao tree was built in 2002,2005 and 2006, and slope, the southeast is than the sloping high 18-4.5% in northwest (seeing table 1).The fruit tree of China's south purple soil massif district orchard planting mainly is oranges and tangerines, and its suitable aspect is slope, the southeast.Therefore, slope, the first-selected southeast is wanted in the orchard addressing.

Explain: the number fruit time is respectively on October 20th, 1993 and on October 25th, 1994.
(2) selection of parent rock rock-layers combination.The purple sand that thick-layer sandstone, the weathering of thickness sandstone alternating layers purple rock form is phosphorous, potassium, calcium are few; And mineral nutrients such as the purple soil that purple sand shale alternating layers such as the thin shale of thick sand, the thin shale of thin sand, the thin thick shale of sand, the thick shale of thick sand and thick shale, weathering form is phosphorous, potassium, calcium are more; Soil drought resisting performance is superior to the purple sand, and is very favourable to plant growing.Therefore, select purple shale and purple sand shale alternating layers.
(3) selection of domatic form.The top on the table top on the bottom that the gradient is domatic in the linear pattern below 15 °, matrix is sloping, stepped ramp type slope, convex slope all belongs to the gentle slope, and the gradient is less than 15 °; The domatic gradient that has is convenient to exposed parent rock and the half-naked parent rock explosion soil building that reveals below 7 °.
2. delimit detonating fuse and borehole point.
3. the directed secondary blasting of fixing a point spring.Elder generation's collaring makes direction heap rubble direction inclination on it, and ties into wisp with straw, is layered on around the borehole; Press trunk again, big gun is put in a glance No. 2 times, earlier fried top layer parent rock, the fried bottom parent rock in back; The gravel of scraping approaches heap (piling 2 layers of gravel) 1-2 layer gravel, and the trench that explodes is gone up wide 1.2m, following wide 1m; Dark 1m, every long 6-20m of ditch, and link to each other with the drain ditch.
4. at autumn in summer high temperature season, stir thin heap gravel 1-2 time, promote that gravel is weathered into soil; Carry out rubble and stack method test, handling 1 is thick heap, and ruckle is more than 4 layers; Processing 2 approaches heap in being, gravel pushes away 3 layers; Handle 3 and be thin heap (2 layers of ruckles), and stir 2 times in summer and autumn.Result of the test shows: thin heap and the gravel that stirs on the hot summer days, maximum with the air contact-making surface, weathering speed is the fastest, becomes native rate the highest with change mud rate, secondly is thick heap (4 layers of ruckles).The stone of thick heap and air contact-making surface are minimum, and weathering is the slowest.Total trend, during the particle after the weathering was formed, each particle diameter granule content all was from coarse to fine successively decreasing, and along with particle attenuates, changed the mud rate and become native rate all to rise.
The particle of the different stacking method wastes of crushed stone is formed unit after the purple rock explosion of table 2 somewhere: millimeter %
5. the purple rock clast backfill of explosion.Autumn end in next year is gone into trench, first backfill coarse granule waste, back backfill fine grained waste with the gravel of detrition and half waste, waste backfill; And fertilizer is inserted in layering: the difficult fertilizer straw that rots, stalk etc. are filled out at orlop, and more perishable fertilizer oil cake is filled out in the middle level, and the fertilizer that is prone to become thoroughly decomposed like animal dung, is filled out on the upper strata, the fertile lid layer waste of one deck.Earth-filling method is formed influence big (seeing table 3) to the native plow layer particle of ladder.Scree is in the trench both sides after the explosion of purple sand shale; Through weathering in 1 year, major part was weathered into the particle of particle diameter less than 10mm, and the fraction particle diameter is more than 10mm; On terraced soil, planted plant for 1 year, terraced native top layer (≤30cm) particle diameter is the bigger the better less than the particle proportion of 1mm.Therefore, when the backfill of purple sand shale waste, be with rake elder generation backfill coarse granule waste and gravel, crushed stone, after fill out the fine grained waste, improve the ratio of terraced native plow layer fine grained and native mud.
Table 3 earth-filling method is to the unit that influences of plow layer grain thickness: millimeter %
6. high level ladder soil such as build.The gradient domatic less than 10 °, 2 trenches of explosion are accomplished the horizontal ladder soil of wide 4m; Gradient 10-15 ° domatic, 1 trench of an explosion is built 1 the horizontal ladder soil that 2m is wide.Every block of horizontal ladder soil, tread will littlely to the inside incline, and injects the drain ditch so that the tread runoff is concentrated, and reduces interflow (water that runs off in soil), and clay fertilizer runs off in the minimizing soil layer.
7. by the fertilising of standard soil moved in to improve the original.The root system of a fruit tree and a kind crop, the overwhelming majority be distributed in≤the dark soil layer of 50cm in.The results showed that, ≤ 50cm soil layer of soil particle composition, less than 2mm granules 23.5% and 25.0% survival rate of 100 percent citrus, growth and development are normal, another difference is small, two-year-old citrus bud significant rate of 90%. less than 2mm particles accounted for 23%, but the rate was only 80% bud; less than 2mm diameter accounted for 20%, the survival rate of less than 90% of citrus, citrus 2 years old is not a bud, less than 2mm diameter accounted for 18%, the survival rate of less than 85 citrus %, 2-year-old is not a citrus bud (see Table 4), at the same time, through the new soil organic fertilizer, soil fertility, and in calcareous soil, purple soil pH, so that all of the decline, is conducive to crop growth.The visitor goes into four discipline laterite red soil, plate shale red soil, limestone red soil (claiming reddish yellow mud, yellow mud, grey yellow mud again), all can regulate soil acidity or alkalinity, especially goes into four discipline laterite red soil (reddish yellow mud) best results with the visitor.Apply animal dung, oil cake, nontoxic rubbish and open grave mud, ditch mud, can both increase the content of plow layer organic matter and nitrogen, phosphorus, potassium, slaking and cultivation soil.
Table 4? MIDDLE Tan Son Town Workers Union Village, different proportions of particles less than 2mm 2 years old citrus growth
Description: Each processing 10 citrus, after observing averaged observation time: 2003.
8. the table of turning over is native
After planting citrus in winter, combined with pig manure, plowing up the gravel and coarse sand pressure fertilizer; 2 years after the determination of 0-40 cm soil particle composition, the results showed that: treatment 1 (once every winter plowing) particles significantly change small, weathered the fastest, parent material into soil and mud is more; treatment 2 (two years plowing 1) followed; treatment 3 (2-year-tillage, not flip) weathered the slowest (see Table 5).
Table 5 is newly opened orchard the influence unit of number of times to the gravel weathering of turning over: millimeter %
Soil temperature changes and to reduce gradually from showing native deep layer, and gravel temperature effect in soil is less, is subject to temperature, rainwater, freezing effect and accelerates physical weathering outward and be exposed to, and makes gravel constantly broken.The also accelerated weathering of mechanism when turning in addition.
9. table soil covers
Orchard childhood of naked rock deserted mountain, purple mound hilllock exploitation, the stone gravel concentration is high in the soil, and particle is thick, and a little less than the water retention capacity, in 7-9 month high temperature and little rainfall seasons, table soil temperature degree is high, and soil water evaporation is strong.Cover with straw, can reduce soil temperature, reduce water consumption, save irrigation water; Volt fine noon in autumn, can reduce surface temperature 5-30 ℃, fall in the soil temperature 1-9 ℃, irrigation frequency minimizing 50%.Plantation Bai Sanye, red clover, July is the withered table soil that covers of blade during high temperature, and the cooling water-saving result is also arranged, and sends out seedling by the end of September again.But the Bai Sanye below the top fruit sprayer, red clover can be got over the summer safely, thus the consumption of aggravation soil moisture, and therefore, straw covers cooling water-saving result best (seeing table 6).
Table 6 Hengyang Basin 7-9 orchard childhood month table soil covers the cooling water-saving result
10, a kind crop, culture fertility improves the soil and utilizes benefit.
Between the species in the first year of citrus trees and thick trunk tree height basically similar, 10 higher than the average inter-planting trees is not room, it seems not only had no effect, but a slight role in promoting.Between planted the 2nd, the 3rd year, the height of tree of a kind watermelon and trunk slightly are significantly less than plants tree, be under some influence (referring to table 7) of growing between the end.
(3) plant the influence to soil fertility in 3 years between continuously
Find out from table 8, a kind 3 years and not between plant before relatively, soil pH value is relatively; Be that alkalescence weakens the content of organic matter and significantly improves, alkali-hydrolyzable nitrogen, rapid available phosphorus potassium are except that 1 year available potassium of a kind reduces; All the other all show a rising trend, and increase with a kind time limit, and each item index improves thereupon.It is thus clear that a kind watermelon has the effect of significantly improving the soil, generally speaking, a kind time limit is long more, to vegetable soil with build up fertility favourable more, because of between the kind watermelon need plowed soils and apply a large amount of pig dung fertilizers, improved soil fertility naturally.But with the main citrus crop age increases, crown volume expansion of aboveground and underground root system gradually developed, the absorption of fat absorption capacity growing, both intensified conflicts between water demand of fertilizer needed, affected the growth of citrus, watermelon yields declining, therefore, between the kinds of watermelons only two years ago, through a kind of watermelon, not only improved the soil, and increased income, can develop side side benefit, to "keep a short length, length of the combination" purposes.Therefore, kind watermelon or other economic crops also are the supplementary measures of a significant between orchard early stage (1-2).Usually, the orchard of planting crop between not, citrus is gone into operation the initial stage, per 667 ㎡ produce 50 kilograms on citrus, and through between the tangerine garden of planting, the operation initial stage, per 667 ㎡ produced 500 kilograms on citrus.It is thus clear that a kind has appreciable impact to citrus production.
