Description

Influence of the different tillage to growth and development of jujube trees

Technical field

The present invention relates to tillage method, more specifically for, more particularly to different tillage pair The influence of growth and development of jujube trees.

Background technology

Tillage method is modern word, is a proper noun, refers to the mode on kind of ground.

Irrigation canal system engineering

Build canals and meet the moisture needs of crop, boiling water ditch excludes the unnecessary water in farmland, is farmland The main task of water conservancy.So irrigation canals and ditches engineering is a kind of most common pattern.Business, all period agricultures The ditch ditch of Tanaka plays a part of to farmland diversion, water delivery, water distribution, poured water and draining respectively. The Warring States Period, countries' contention for hegemony, to reach purpose of making one's country rich and build up its military might, water conservancy is extremely paid attention to, greatly Type Canal System Construction is rapidly growing.Zhang water ten is built with hosting in Wei state west gate Bao Jin Hebei Linzhang one Two canals, are Chinese earliest large-scale canal system.From between the following centuries of the Western Han Dynastry, this area is always Important political economy region.3rd century BC, another name for Sichuan Province keeps Li Bing hostings and has built well known Dujiang Weir project, two thousand yearses are lasted so far without useless, benefit is growing on and on.Dujiang weir is built It is diversion without dam canal system in Ming River alluvial fan landform.Canal engineering is main by Yu Zui, Aguarius Mouth and the part of blown sand weir three composition.Whole project planning is rationally distributed, and design concept is ingenious, pipe Reason uses science, working drawing review economy, is rare outstanding in ancient Chinese irrigation canal system Engineering.After building up, Sichuan Plain satisfies that " non-irrigated then diversion infiltrates, floods and droughts that rain then stops up water valve ... From people, do not know famine, when the self-sufficient and strategically located region without famine year, all over the world meaning ".Zheng state on the central Shaanxi plain Canal is a largest ditch system project, is presided over and built by water conservancy project Zheng state.Jing Shui is drawn in canal west, In east note Luo Shui, trunk canal total length more than 300, plan irrigated area is up to 40,000 hectares.Ssu-ma Chien is evaluated Effect of the Zhenggou canal played in Qin Tongyi causes is said：" just, the water that silt is filled out with note irrigates damp halogen to canal Ground more than 40,000 hectares, receive all clocks of mu one.Then the Central Shanxi Plain is fertile field, no year of crop failure or famine.The Qin with rich and powerful, Soldier and nobility ".During the Western Han Dynastry, irrigation canal system engineering continues have development, and Guanzhong area has been built up in vain Canal, six auxiliary canals, Cheng Guoqu, illiteracy verdant canal, Ling Zhiqu etc.；In the modern Hetao area and Hexi Corridor " all irrigation channel and Chuan Gu (water) to irrigate field "；Xinjiang Gu Luntai (modern Luntai County), canal plough are (modern Ku Leer counties), Yi Xun (the modern band of Qarkilik County one), Che Shi, Lou Lan (the northern bank one in modern Lop Nur Band) and the ground such as Yiwu (near modern Hami) also more engineering irrigation.After the Western Han Dynastry, irrigation canal It is that the development of engineering lies substantially in dead state, simply slightly has construction in few places.

Pond irrigation works

Pond pool system is using nature physical features, the water storage engineering by manual sorting, and its function is retaining Irrigate field.The record of pond pond irrigated farmland is utilized in document before two thousand yearses：" Biao Chi Bei Stream, soaks that rice field." Chinese herbaceous peony pond was built in the Spring and Autumn and the Warring States Periods, was an earliest large-scale fill Catchwork irrigation engineering, " there are five, Tu Na rivers stream in pond ".In diameter about hundred, surrounding about three In more than hundred, on the south the modern Shouxian County, Anhui Province of perfusion 40,000 hectares of fields between Pi Shui and rich water.The peace of today Feng Tang is exactly its remnant.Han dynasty, the pond pool is emerging to build very common, after the Eastern Han Dynasty, pond Tang Shui Sharp accelerated development.Dyke Water Conservancy appropriate building originates in Basin of Huaihe River, Runan, the Chinese in knob Middle area is also quite flourishing.From the unearthed Eastern Han Dynasty's pottery pond pool model in Yunnan, Sichuan, it can be seen that at that time Breed fish, comprehensively utilized in the pond of pond.《Huainan says that woods is instructed》In be related to the pond pool The calculating of irrigated area quantity：" ten hectares of pond can fill 40 hectares." the middle-size and small-size pond pool is suitable to The peasant household of small peasant economy builds, and southern area rainy season retaining when arid in case use, and build is outstanding more. Yuan Dynasty Wang Zhen《Agriculture book Nongqitupu irrigates door》Say：It is " only southern ripe in water conservancy, official pond The official pool has it everywhere.Among the people is small stream Dam, pond certainly, it is difficult to number meter ".The Ming Dynasty only Jiangxi one Just there is tens thousand of of the pond pool on ground.In a word, the pond pool that ancient times spread all over the world, the effect to agricultural production It can not underestimate.

Tang Pu low-lying paddy fields system

Sui, Tang, Song's period, water conservancy construction is throughout on both sides of the Changjiang River, the Tang Pu low-lying paddy fields of Taihu Lake basin Build on a large scale especially prominent.Ancient times TAI HU AREA working people is in shallow water marsh, or river lakeshore Ground fill of fetching earth is enclosed and cultivated and wards off field, and fill is fetched earth part, ditch ditch necessarily occurs.In order to solve ponding Problem, and this kind of embankment, ditch ditch are extended, then gradually become pool Pu.Work as development To crisscross pools close proximity, when gate control irrigation and drainage are set, the pool as checkerboard type is just developed Pu low-lying paddy field system.Song Dynasty model is secondary to be flooded《Answer emperor's autograph edict and state one item after another ten things》Road described in (1043)： " in the old low-lying paddy field in the south of the River, each country fair number formulary ten, such as big city, in have rivers and canals, have gate outside, It is non-irrigated then open a sluice gate to draw the profit of river, it is hasty and careless, the evil that lock refuses river is closed, drought and waterlogging are too late, are Nong Meili.” The Tang Pu low-lying paddy fields of TAI HU AREA were formed at after middle period the Tang Dynasty.During five generations Wu Yue State using army and Impress labour husband and dredge river levee, maintenance system of strengthening management sets up " all Shui Ying fields make " government post, Combine harnessing the river with controlling field.Development and consolidation of these measures to Tang Pu low-lying paddy fields serve good Good effect.At the beginning of the Northern Song Dynasty, Taihu Lake basin Tang Pu low-lying paddy fields are useless without controlling, and mid-term sets about repairing and renovate again.South It is big during Song to contain, make many dredging ports Pu and levee-surrounded field puts the engineering of lock etc.

Maritime work

Zi Han, Tang Qi, river, Zhejiang, the ALONG COASTAL FUJIAN people start to build for defence tidewater disaster Jiang Haidi prevents.Seawall is occupied quite important during the economic development of Area In The Coast of Southeast China Status.Develop into Shitang from Tu Tang, Building technology level is not from part to even being aligned in seawall It is disconnected to improve.When five generation Wu Yueguo money Liu are in place, flood gate and Tongjiang were once waited in Hangzhou, and ponding is prevented outdoors Tide, " stone stores up timber method " used, using paling as lattice, masonry is filled into lattice, after filling silt through the sand that rises, Just turn into the native Shitang firm more than the native pool.It may be said that this is the transition from Tu Tang to Shitang.North Song Shi, the technical once reform in Shitang is exactly to employ " slope stick together method ", i.e., seawall is slope Stone step formula, pool body stability acts the power that disappears again better than formula seawall of standing like a wall, slope rank.When bright, clear, Maritime work is more paid attention to, and as many as human and material resources of input and technical progress are above Other periods of history.

Well irrigation

This is a kind of engineering pattern using underground water.The origin of Chinese well is very early.According to archaeology money With regard to having excavated out well in material, the Longshan culture ruins before more than 4,000 years away from the present.The many places in the north Surface water is not enough, therefore payes attention to development well irrigation.Since the Warring states, northern well irrigation is fairly popular, the successive dynasties Government also advocates sinking shaft.When bright, clear, in modern Guanzhong, Shanxi, Shanxi Fen is swum under water, Hebei, Henan plain area forms well-irrigated area.Fang Chengguan《Cotton is schemed》Middle theory：" plant cotton must sinking shaft, One well can irrigate Tian Sishi mus." karez, it is that Xinjiang region utilizes Tianshan Mountains, Altai Mountains, elder brother The snow-broth of snow melting leaks into the underground stream or diving of gravel layer and irrigated by the foot of a mountain on logical sequence mountain A kind of unique forms.Karez just has in the Western Han Dynastry.People are rare according to local rainfall, gas Wait hot, vertical shaft in column is dug in the characteristics of dust storm is big, the area communicated in subsurface flow, its Under have horizontal canal (closed conduit), then water is sent in farmland by open channel (irrigation canal).This Sample water row underground, can reduce evaporation.The Qing Dynasty, Lin Zexu once widelys popularize in the band of Turfan one, Turfan agricultural development to hot arid has played great role.

Agriculture tool of production

Agriculture tool of production has been referred to as " field device ", " agriculture device " and " agriculture since the period in Spring and Autumn and Warring States Tool ".The raw material of farm implements is manufactured, is stone, bone, freshwater mussel, angle etc. earliest.Business, Zhou Shidai occur Bronze farm implements, species has Ben, Cha, axe, Qiang, Bo, shovel, weeding hoe, sickle, plow-shape device etc.. This is a major progress in Chinese farm implements history.The metallurgy technology invention of Chinese iron is started from the latest Spring and autumn.When period in Spring and Autumn and Warring States, smelting iron technology successively occurs in that pig iron metallurgy, steel-making and the pig iron are soft Change three technology, ironware is turned into the sharp tool more rich in wide future, accelerate iron farm implements Instead of wood, stone, bronze farm implements processed historical progress.The use of iron farm implements is in agricultural production One turning point, it can remove large stretches of forests, be allowed to be changed into arable land, pasture, also make large area Field farming be possibly realized；Even plant agricultural production relation, soil cultivating system and crop A series of change also occurs for training technology etc..The farm implements of ancient Chinese can be divided into following several by function Class：

Intake equipment

Diversion irrigation, it is most important that try the water of lower to guide eminence into.In this respect, in There were many dexterous inventions ancient times in state.Familiar waterwheel, is also named " overturning ", " dragon Bone car ", " kyllinga brevifolia ".When it comes across the Eastern Han Dynasty, three states, initially only it is used for pouring garden Ground, it is widely used by the peasant in paddy field area later, nearly over 2,000 years, risen always in production Larger effect.Cylinder car, is also shown in many places, goes through within about more than thousand today History.This is, a big runner, around to fasten many thick bamboo tubes or wooden cylinder, be placed in waterside, A runner part is not in water, current excitement runner, and the cylinder on wheel is just drawn successively in a stream In the field of water note ashore.Yuan Dynasty Wang Zhen《Agriculture book》In the water recorded turns to overturn, ox turns to turn over Car, donkey turn overturning, high rotating cylinder car, and construction is more complicated, and efficiency comparison is high, is all from overturning Change out with cylinder car.High rotating cylinder car can guide to water in more than ten zhang high places.In order to Water is guided at a distance, then has the invention of even cylinder and rack slot.Even cylinder is in thick bamboo pole is removed The section in face, is connected one by one, below with physical features relative superiority or inferiority, is erected with lifeless thing, can be crossed over Jian Gu, guides to water in far place.The design of rack slot substantially connects together as cylinder, simply uses What it is with diversion is trogue.This appliances, as described in Wang Zhen：" it can moisten down in thousand hectares greatly, Gao Kefei is flowed in hundred chis, and frame then far reaches, then logical, four rescued invariably in this world that dive in cave, on the ground Have can be emerging rain." reflect ancient Chinese this respect creativity and innovation it is ingenious, efficiently and It is practical.

Plough smooth farm implements

Plough-like farm tool used in ancient China is to plough the main tillage implements before generally use.Spades, iron that its similar modern times also uses Spade, also You Jiao Cha's.The cultivated plough drawn using farm animal, China since period in Spring and Autumn and Warring States just gradually Used in some area popularizations.The wooden ox plough specification of a model in Gansu Mo Zui unearthed Western Han Dynastry's last years of a dynasty or reign Han dynasty is ploughed plough and finalized the design almost.Zhao crosses the coupling plough of popularization " two N of three people ploughs " during Emperor Wu Di of the Han dynasty, has The parts such as beam, the plough tip (plow stick), plough bottom (plough bed), plough weighing apparatus, plough arrow.Mouldboard is (again It is mouldboard or plough bowl) it is widely used in Han dynasty.The plough of Han dynasty is the long shafts plough of straight shafts, during arable land Later turn underaction, play that soil is laborious, efficiency is not bery high.By updating, to the Tang Dynasty New crooked shaft plough has been formulated, work " east of a river plough " is called.Testudo elongata was covered at that time《Plough-like farm tool used in ancient China is passed through》In in detail Carefully describe its part, size and effect.This plough is by Li Chan made of iron, mouldboard and wooden Plough bottom, Ya Chan, plough plan, plough arrow, beam, the plough tip, plough comment, plough build, soil shoe etc. 11 Individual part composition.Whole plough of ploughing is quite complete, advanced, is that the cultivated plough of China develops into comparative maturity The typical case in stage.China's plough is ploughed also referred to as frame shape, is because plough body is by bed, post, handle, shafts Constituted Deng part, in the cause of frame shape.Shafts plough, the square plough of Germany, Russia are hooked compared with Mediterranean Ross is to plough, India's plough, Malaysia plough etc., and plough body can be swung when its advantage is operation, rich Have mobility, be conveniently adjusted tilling depth, working width, and it is light and handy it is soft just socialized beneficial to revolution, be suitable to The farming on small area plot.In addition, using curved surface mouldboard, not only can preferably hack, Upturned soil can also be played and make ridge, drilling is carried out, operate and manage beneficial to field.Song Dynasty invented step on plough and Several manpower ploughs have been invented again by colter, the Ming Dynasty, but all application is not wide.Turning in addition to plough Soil working tool also has Dong and an iron rake with three to six teeth etc..After farmland is ploughed, hack must be passed through and smooth.Smooth agriculture Have earliest You Harrow (vertebra), flog later, labor (a kind of farm tools), rake, stone roller etc..Gansu the Jiayu Pass There is the image of rake and a kind of farm tools in the Wei Jin mural painting in tombe chambers that city is found.It is unearthed in the Western Jin Dynasty tomb of Guangdong Tao Shuitian plow harrow models, plough and rake are all drawn with ox.The harrow-like implement for pulverizing soil that paddy field is operated with, Wei Jin Shinan Side has also more generally been used.

Farm tool for sowing

Most important creativity and innovation is an animal-drawn seed plough, and the popularization of grain Zhao Duwei excessive forces is searched when being Emperor Wu Di of the Han dynasty One of new farm implements.According to Eastern Han Dynasty Cui Shi《Political comment》Say：" its method three ploughs totally one N, a people by it, Sow and draw an animal-drawn seed plough, all take it is standby here.Day plants one hectare, so far three auxiliary still Lai Qili." " three plough " be Three an animal-drawn seed plough pin.There is a people to sow drawing an animal-drawn seed plough on Shanxi Pinglu jujube garden Western Han Dynastry late period mural painting in tombe chamber, its An animal-drawn seed plough exactly three pin an animal-drawn seed ploughs.Sowed with an animal-drawn seed plough, one N of traction an animal-drawn seed plough a, people helps an animal-drawn seed plough, and seed is contained in an animal-drawn seed plough In bucket, an animal-drawn seed plough bucket is communicated with hollow an animal-drawn seed plough pin, and is gone and shaken, and kind is under.It can be completed simultaneously Ditch, sow, earth backing three process.Three rows are once sowed, line-spacing is consistent, sow uniform, Substantially increase sowing efficiency and quality.

Tillage and weeding farm implements

One class is money, shovel and small pot with a handle and a spout for boiling water or herbal medicine, and construction is similar, is substantially same farm implements.Ancient times text Offer and be often used for mutually annotation,《Origin of Chinese character》14：" money, small pot with a handle and a spout for boiling water or herbal medicine, Gu Nongqi.” This kind of farm implements need to be pasted ground grafter with wrist strength and be loosened the soil with weeding, it is also possible to dig.It is another Class is Nong, Bo and hoe, and just construction is said also similar, is all to exert oneself backward with thinning, weeding With the farm implements loosened the soil, than money, shovel, small pot with a handle and a spout for boiling water or herbal medicine progress a bit, still it is widely used so far.Spring and autumn Iron hoe is there has been during the Warring states；What the later iron hoe of Han dynasty and modern age used there is no that what is poor It is different.It is the weeding in paddy field to weed, loosen the soil farm implements.Wang Zhen《Agriculture book Nongqitupu Qian Bo》 In weed figure.When Song, member《Plant to transplant and speak out》Middle first time describes an animal-drawn seed plough hoe.This is one The tillage and weeding and ridging farm implements of kind animal-drawn.

Harvest farm implements

The Neolithic Age existing Sickle and sickle made of stones or clam shell for extracting cereal tassel and ligusticumic stalk. After metal occurs, then there are Sickle bronze and made of iron and sickle.For thousands of years, the shape base of Sickle and sickle There is no much changes on this.Song Yiqian, have also appeared and dial sickle, Chinese mugwort, screen sickle, push away sickle, scimitar Deng harvest farm implements.Wang Zhen《Agriculture book Nongqitupu》Described in constituted by wheat samarium, wheat are ample etc. Mow wheat device, be a kind of farm implements of more advanced harvest wheat.After grain harvest threshing, profit The method that not plump shell and seed are separated with proportion and wind-force is used very early.From《The Book of Songs》In Proof can be found：" Wei Nan has dustpan (one of skip bucket, star names, twenty-eight constellations), it is not possible to Winnow." the unearthed pottery windmill model of 1973 years Jiyuan, Henan Xian Si ravines ditch tomb of Han dynasty, illustrate at the latest Late period has been invented cleaning seed by the Western Han Dynastry, separates the effective tool of chaff.Windmill turns blade Dynamic raw wind and Seed weight are then sunk, the experience of chaff Qing Ze Yang is dexterously combined in same machinery, A kind of really novel creation.
