Description

The Rice Powder ridge cultivating method
Technical field
The present invention relates to the tillage cultivation method of crops, is the tillage cultivation method of a kind of paddy rice specifically.
Background technology
Paddy rice is one of most important cereal crops of people, for thousands of years, human plantation to paddy rice has had the ripe methods of cultivation of a cover, from whole ground, seed selection, grow seedlings, rice transplanting, intertill and clean tillage, fertilising is to harvesting, theory and practice has a lot of Experiences, as if no longer include necessity of research, ancient books literature record from the successive dynasties, people have been familiar with the wet rice cultivation method very early has very important must a relation to the good quality and high output of its growth, for example the Dai Tianfa that comes into one's own of Middle West Han Dynasty and Qu Tianfa adapt to the soil one crop system and the cropping pattern that produces, recovery for the ease of soil fertility, change the original casual system of removing for field system, play the ridge culture ditch between fields in the farmland, the ditch of Crop Species under the ridge is in the ditch between fields, the ditch between fields reciprocity of Second Year ridge, soil fertility obtain local rest and reorganization.Open premodern agriculture textbook and Agricultural Periodicals, we also know present wet rice cultivation method deep ploughing, shallow plowing, the method that no-tillage and several farming combine, traditional rice transplantation by hand also becomes rice transplanting gradually, live, before modern mechanical dissolves now, owing to being limited to the tool of production, peasants use hoe, shovel, plough, rake, farming is a kind of effort and arduous work, therefore shallow plowing and no-tillage be Main Means, its shortcoming performance has the following aspects: 1, with manpower or animal power farming, general tilling depth only has 10 to 15 centimetres, continue to use manpower or animal power ploughs throughout the year, between plow layer and real soil layer, just formed the approximately tillage pan that hardens more than 5 centimetres of one deck, the root growth of crop is subject to certain restrictions.The permeability of soil is bad, is unfavorable for the growth of crop root, lower bundle; 2, irrigation of paddy fields mostly is flood irrigation, string is filled with, and fertilizer efficiency easily runs off and volatilizees; 3, soil shallow, water retention property is relatively poor, and the surface runoff loss of water is large, and efficiency of water application is not high; 4, because soil shallow, dry field easily hardens, and permeability is poor, and difficult growth of rice root and causing yields poorly, poor quality, and farmers' income just reduces.Although in recent years, the artificial farming such as hoe, shovel, plough, rake has become tractor or other farm machinery farming gradually, plough deeply and also be increased to 20 centimetres by 10 to 15 centimetres, but deep ploughing only only limits to mellow soil layer, multi-purpose plough is smashed earth after turning over, if earth viscosity is difficult to more greatly smash; In addition, even ridging also is simple furrow, so that technology is ploughed deeply in present soil is unfavorable to the growth of paddy rice, can not satisfy the demand of rice root.
From as seen above-mentioned, suitably deep ploughing is paddy rice and the innovation of other crops tillage cultivation method and the important measures that are conducive to crop yield, but, the subsoiling of how deep ploughing, a lot of agricultural experts are also studying, and also do not form unified standard, therefore on the basis by practice and further investigation, find a kind of technology of the subsoiling of deep ploughing according to Different Crop, will bring a larger promotion to agricultural from now on.
The inventor carried out some researchs to the deep ploughing subsoiling of proportion of crop planting, for example applied in 2009 " method for planting dryland crops by crashing soil ", application number: 2010010125942.4 Chinese patent, summary, the tillage cultivation method of this dry land crop adopts rotary tillage screw type mechanical deep pine ditch, silt, plow layer and tillage pan is loosened the soil pulverize and the soil moved in to improve the original floating of part tillage pan becomes the ridge naturally with the soil mixing of plow layer, after machine ditch silt becomes the ridge, can sow or plant.Can determine to adopt different line-spacing and ditch depth specification according to Different Crop plantation demand.Adopt this inventive method, the soil cultivation holostrome is rarefaction, and played the soil moved in to improve the original effect of improving the soil in the zanjon rotary tillage, preserve moisture and fertility ability and the permeability of soil have been improved, be conducive to the dark utilization of pricking liquid manure of crop root, disease is relative with weeds to be reduced, and crop yield increases substantially, generally can increase production more than 20%, high reaches more than 100%.
Summary of the invention
The purpose of this invention is to provide a kind of paddy rice deep ploughing subsoiling and the tillage cultivation method of random soil layer not, can overcome existing shallow plowing process to cause land quality day by day to degenerate, soil compaction is serious, and the problem that permeability descends improves the output of paddy rice.
Technical scheme of the present invention is achieved in that

Embodiment 4
Test site, Beiliu City, Guangxi, in February, 2011 the powder ridge, March 6 sowing, 12-13 day in April transplants, kind is Y two excellent No. 1.Subsoiling 20-30 centimetre, the row's of filling ditch is set between railway carriage or compartment (ridge), according to the cultivation strategy of " do powder ridge, field; subsoiling native (the suitable tillage pan of protecting) alive, ditch is established in a minute railway carriage or compartment, and water saving is irrigated through furrow; alternation of wetting and drying, and the oxygenation of breathing freely is conducted heat with gas; support the root mulch, realizes increasing " source " expansion " storehouse ", and strong bar increases production " and the cultivation theory of " outstanding take root as this; as to educate root and support the root mulch; root is strengthened body by force, promotes production with root ", implement.Transplant after 30 days, find that powder ridge cultivation well developed root system and powder ridge soil still keep graininess after soaked, do not harden.The plant strain growth situation as shown in Figure 3.
The inventor draws following cognition through the experiment of two Rice Powder ridge cultivations in season:
Rice seedling transplanting and throwing plantation behind the slurry rake that will pass through plough, harrows or turn over of tradition rice cropping, the paddy rice of powder ridge cultivation, then adopt disposable vertical turnery to pulverize, subsoiling and not random soil layer, topsoil thickens with soil structure and improves, and water saving economizes fertile, the breeding good method, to educate the strong root of root as basic, can realize minimal tilling abridged edition, saving of labor energy-conservation, break through normal purpose of producing.
By test and perfect, reform existing traditional rice cropping pattern, make the cultivation of Rice Powder ridge drive transformation and the optimization of rice field tillage method, cropping system, thicken paddy field plow layer, reduce the mechanical work number of times and realize energy-saving and emission-reduction, necessary water saving is irrigated and efficiency cultivation technology for high, improve paddy field water either resource and utilization rate of fertilizer, improve the planting benefit of rice field integrated production capacity and crop thereof, shift and Ensuring Food Safety for adapting to China rural laborer, explore the crop yield new approach such as paddy rice.
The direction of exploring: the one, by the cultivation of powder ridge, thicken paddy field plow layer and improve ecological environment of soil, for paddy rice and other plant growths provide new good soil condition, realize the fertile abridged edition high yield of water saving joint.The 2nd, by powder ridge cultivation, can try early the crops such as season powder ridge cultivation super hybridization rice+season in evening no-tillage cultivation paddy rice+autumn and winter cultivation no-tillage cultivation potato, rape; Powder ridge plantation in winter potato+season morning no-tillage cultivation super hybridization rice+season in evening rice of no-tillage; Utilization season morning powder ridge cultivation super hybridization rice well developed root system and the stronger advantage of vigor, the development ratoon rice is results ahead of time, and then the circulation tillage method such as development autumn and winter cultivation crop and reduce the mechanical work number of times, realize driving the optimization of multiple tillage method and cropping system and efficient with the cultivation of powder ridge.The 3rd, by the cultivation of super hybridization rice powder ridge, exploration whole field, powder ridge, fertilising, sowing, weeding are equal to machine integrated operation, realize increasing substantially of mechanization production efficient, and the labor amount significantly reduces.
The inventor thinks, the cultivation of Rice Powder ridge is different from planting dryland crops by crashing soil, is a kind of brand-new rice cultivating technique.Powder application ridge machine was disposable when it referred to the rice field dry ground pulverizes and naturally suspends into railway carriage or compartment (ridge) with the vertical turnery of topsoil, the row's of filling ditch is set between railway carriage or compartment (ridge), subsoiling and not random soil layer are in the planting season of rice cultivation and keep powder ridge soil structure, the water saving oxygenation gain of heat, support the culture technique that root mulch etc. matches on the face of railway carriage or compartment (ridge).
The cultivation method that the inventor proposes has three kinds of Rice Powder ridge planting patternss: under (1) wet condition, directly sow the powder ridge direct sowing culture of plantation on the face of railway carriage or compartment, powder ridge.(2) throwing-seedling cultivation behind rice field, the powder ridge backwater immersion weak soil; (3) rice transplanting was cultivated after rice field, powder ridge backwater soaked weak soil.
The basic principle of Rice Powder ridge cultivation is: take full advantage of paddy field plow layer and the long-term deposition of following part " decrepit and behind the times soil " and natural rainfall, realize subsoiling (more than 20 centimetre) soil moved in to improve the original and not random soil layer, naturally soft and do not starch knot after backwater soaks, Zang Shui and do not affect ventilative (soil is spongy); Water saving furrow irrigation regulation and control realize the oxygenation gain of heat, improve water and fertilizer utilization, grow and have created the ecological environment of soil of " soil, water, fertilizer, gas, heat, bacterium etc. are completely newly coordinated " for satisfying super hybridization rice.
This technology, fundamentally solve and overcome the traditional cultivation paddy rice will through plough, harrow or the slurry rake of turning over could throw the soil layer shallow (mostly being 15 centimetres) that exists in the mode such as (inserting) seedling, fall to doing easily harden, long-time flood irrigation string filling easily causes clay fertilizer water seriously to run off, the waterflooding anaerobism easily causes root system few and mostly be sepia and peculiar smell is arranged for a long time, is difficult to the significant drawback of increasing production again.
The cultivation of Rice Powder ridge is different from traditional rice cropping fully, and its basic principle is: outstanding take root as this, and to educate root and support the root mulch, the strong stalk of strong root is promoted production with root.
The cultivation of Rice Powder ridge has broken through traditional rice cropping pattern, and its elementary tactics is: do powder ridge, field, subsoiling is lived native (the suitable tillage pan of protecting), ditch is established in minute railway carriage or compartment, water saving furrow irrigation, alternation of wetting and drying, ventilative oxygenation, conduct heat with gas, support the root mulch, realize increasing " source " expansion " storehouse ", strong bar volume increase.
According to above-described embodiment, the technical essential that the inventor sums up the cultivation of Rice Powder ridge is:
1, whole field, powder ridge: ditch (waiting to plant) is established on dry ground powder ridge, a minute railway carriage or compartment;
2, transplant cultivation: the backwater weak soil, shallow water is thrown (inserting) seedling; (direct sowing culture: moistening live, alternation of wetting and drying)
3, the management of turning green: the solid root of shallow water, very seedling is turned green;
4, tiller early stage: shallow wet short root, low position tiller;
5, tiller the Sheng phase: ditch-water is supported root, makes every effort to promote the seedling number;
6, control seedling control tiller: reveal the ditch depth root, make up colony;
7, the strong bar of dry field: hondo oxygenation, the strong bar of strong root;
8, strong stalk nourishing the fetus: backwater is moistening, the strong tire of the root of living;
9, heading is solid: moistening guarantor's root, Wang Genbaoye.
