Description
Technical field
The present invention relates to a kind of rice cultivating technique, particularly wet kind of the culture technique of paddy rice furrow ridge formula.
Background technology
Paddy rice is the staple food crop of China, and rice is the staple food grain of Chinese 60% population, and the peasant household of about 50% is engaged in rice and produces, and it is China first farming that rice does.Have a large population and a few land the fundamental realities of the country of Shui Shaoshi China, how to utilize limited land resources and freshwater resources, ensureing China's grain security, is the principal proposition that rice does scientific and technological progress.
Researcher of the present invention think last century paddy rice Dwarfing gene and sterile gene study and utilization success, scientific and technological progress is done to promote the rice that paddy rice short-stalked variety and hybrid rice are core technology, always produce for making China paddy rice and increase by 265% than in the early days of foundation, per unit area yield improves 226%, for China's grain security makes tremendous contribution.When affirming fully the positive effect of above-mentioned " green revolution ", also introspect its negative effect: rice work is to the Progressive failure of ecological resources and high cost thereof.This invention makes based on a new round rice technical concept reformed, and the rice technology of innovation environment close friend, safeguards that grain security and Environmental security are laid equal stress on.
1, one of the drawback of traditional rice technology: freshwater resources high flow rate.
China's regimen is very fragile, is one of country of 13 lacks of water in the world.The world is year freshwater resources 10,000 m per capita
3, China only measure for this reason 20.8%.Plough and occupy fresh water amount 35295m every year in the world
3ha
-1, China be only its 57.6%.China is large agricultural country, and agricultural water accounts for 88% of national water consumption, and Rice Production water accounts for 65% of agricultural water, is the first rich and influential family of social all trades and professions water.According to authorities' prediction, the year two thousand thirty will be China's lack of water peak period, and the annual water resource per capita of China is only 1760m when the time comes
3, close to the 1700m that FAO (Food and Agriculture Organization of the United Nation) is assert
3critical poor-water level.
Rice is made for China all trades and professions water first rich and influential family do activity, and habitual Deep irrigation (basining irrigation) is main cause.Basining irrigation is the water management traditional approach of Chinese rice technology, and is considered as the basic measures of rice high yield.According to the study, disregard atmospheric precipitation, paddy fields in south china per hectare irrigation water about 7500 tons, northern irrigation water needs 15000 tons.Paddy fields in south china cropping index is high, by per hectare rice field water requirement 1.2 × 10
4ton meter, national existing rice field 2880 × 10
4ha (4.32 hundred million mu), wherein about has 666.7 × 10
4though ha rice field possesses the irrigation system that development rice does, receive because insufficient water sources is difficult to protect, actual have Irrigated paddy field about 2213.3 ten thousand ha.Annual this part Irrigated paddy field water consumption 2,656 hundred million tons of China (in average every mu of rice field water consumption 1200 tons), account for 53.3% of (4,987 hundred million tons) of whole nation year water consumption, namely China plants the freshwater resources that rice consumes half every year.Add the loss of engineering and non-engineering, the production efficiency of water per ton is very low, is only 0.6-0.8 kg/tonne, is equivalent to " ton water jin grain ".
2, the drawback two of traditional rice technology: fertilizer and pesticide high investment.
Fertilizer and pesticide is given prominence to stable and the area output effect of rice office of raising China.But since the seventies in last century, improve rice and more and more rely on fertilizer and pesticide, for asking high yield luxury to use chemical fertilizer, the bad habit of unordered applying pesticides have been looked normally.China's chemical fertilizer applications of pesticide amount remains high, and compared with international chemical fertilizer applications of pesticide level, than FAO (Food and Agriculture Organization of the United Nation), fertilizer amount assert that unit are chemical fertilizer safety using amount exceeds standard 40%.The average per hectare of various agricultural chemicals uses 9900g, and about containing each effective constituents 3000g, Yangtze River Delta developed regions rice makes dosage per hectare and reaches 13110g, for Europe, 2 ~ 3 times of American States' dosage.
3, the drawback three of traditional rice technology: to environment high pollution.
Rice is multi-level as environmental pollution, and paddy rice is the model plant of Agricultural Tri-dimension Pollution.The first, rice field is greenhouse gases CH
4with N
2the main source of release of O; The second, superfluous agrochemical material remains soil, threatens quality of rice safety, and spoiled soil agricultural productive force; 3rd, pollute surrounding body, cause Water Eutrophication; 4th, circulating effect, worsens rice place of production eco-environmental quality.
According to environmental ecology research, Chinese agriculture is produced and to be run off pure N about 2,000 ten thousand tons to surrounding enviroment every year, about 4,300,000 tons, agricultural chemicals, not only annual direct losses 200 ~ 25,000,000,000 yuan, and serious environment pollution.First be pollute freshwater resources, China 407 monitoring stations are to the observational study of 92100km rivers, and the section of existing 49.7% is contaminated.Lake is also because of contaminated, and lake water eutrophication is serious, and the average leaded wastewater of lake water such as Taihu Lake, Dian Chi, Chaohu reach 3 ~ 5mgL
-1, on average containing P
2o
5amount reaches 0.1 ~ 0.35mgL
-1, be bio-diversityly subject to heavy damage, water quality is smelt as of rotten fish, and aquaculture declines.
Summary of the invention
The invention provides wet kind of the culture technique of a kind of paddy rice furrow ridge formula, adopt green manure to increase soil fertility, the wet kind of cultivation of furrow ridge formula, effective Limiting Irrigation water, with stable yields abridged edition for core, is aided with water saving and increases soil fertility as target, realize the energy-saving and environmental protecting of rice technology, ensure grain and ecological safety.
The technical solution used in the present invention is:
Wet kind of the culture technique of a kind of paddy rice furrow ridge formula, comprises the steps:
(1) fertile rice crop rotation, winter sows green manure: plant Chinese milk vetch or soybean or rape during slack season in winter, or straw-returning, and land used of increasing soil fertility combines, biologically rehabilitating soil fertility;
(2) bedding is live: water farming furrow, furrow face width 3-5 rice, furrow width and each 0.3-0.5 rice of ditch depth, and it is quantitatively live that bud paddy presses furrow, and hybrid rice seeding quantity is 0.8 ~ 1.5kg/ mu, and conventional Rice seeding quantity is 3 ~ 5kg/ mu; Described live comprising broadcasts sowing or drilling;
(3) rice is irrigated: adopt wet kind of non-irrigated pipe Irrigation, by water starch management breeding time: meet Rice Physiological need water prerequisite under control water utilization, utilize natural precipitation, irrigating except fertilising dispenser is formed except water layer, the time of infertility does not set up water layer, keep ditch-water continuous, guarantee furrow face ground moistening.
In step (1), spread fertilizer over the fields leguminous green manure Chinese Milk Vetch Seeds 1 ~ 1.5 kilogram during slack season in winter, before surviving the winter, clear up ditch, to protect face, field not ponding; The most prosperous, that biological yield is the highest initial bloom stage of nourishing and growing next year is turned over lower soil, uses quicklime 20-30 kilogram for every mu, for neutralization because Chinese milk vetch decomposes the decline of the P in soil H value caused.
Green manure Chinese milk vetch is poured water before containing and spending and is turned over, and accelerates fertilizer uniform decomposition, and water in field is not arranged and is left to the front corrugate bedding of sowing, and venting Soil surface water before sowing, wet soil is sowed.
Paddy rice, at after planting 7 ~ 10 days every mu of fertile urea 8-12 kilogram of supplementary wean, sows 20 ~ 25 days every mu of supplementation administration 10-15 kilogram urea, 20-30 kilogram potassium chloride, 15-20 kilogram superphosphate.
In step (2), bask seeds before seed soaking, Seed soaking 36-48 hour, vernalization 36-48 hour after washing, bud paddy is sowed.
In step (3), keep shallow-layer ditch-water seedling stage, furrow face soil saturation water-holding capacity >=70%, meet the high and dry weather of high temperature, when morning, blade tip was without dewdrop, ditch is entered in instant moisturizing, to building the good soil environment of root growth.
In step (3), ear differentiation stage ditch-water is continuous, keeps the moistening no water layer in furrow face; The Qi Suizhi maturing stage keeps ditch-water continuous, must guard against and cuts off the water supply too early, to the dry yellow maturity of rice strain green grass or young crops, tall and straightly not to fall, full seed during results.
Wet kind of the culture technique of paddy rice " furrow ridge formula " is having the active water-saving technology under stable source of irrigation water condition, and its basic norm is: Limiting Irrigation water, utilizes natural precipitation as far as possible; Appropriateness Limited Irrigation, but do not limit physiological water requirement; Except fertilising medication is filled with except thin water layer, the time of infertility does not set up water layer.Concrete operations are the innovation irrigation programs by building breeding time:
" wet soil sowing ": green manure Chinese milk vetch is poured water before containing and spending and turned over, and accelerates fertilizer uniform decomposition.Water in field is not arranged and is left to the front corrugate bedding of sowing, and drain Soil surface water before sowing, wet soil is sowed.
" shallow water seedling-protection ": until 2 ~ 3 leaf phases, need shallow water seedling-protection, and it is fertile to execute wean, promotes early to send out.
" non-irrigated pipe Baconic ": seedling stage, ditch-water day by day reduced, but soil still keeps moistening, keeps >=70% soil saturation water-holding capacity, and rice strain blade morning " guttation " is normal.Weather as high and dry in high temperature, blade in morning " guttation " abnormal (blade tip is without dewdrop), ditch was entered in instant moisturizing, to building the good soil environment of root growth.
" ditch-water educates fringe ": ear differentiation stage ditch-water is continuous, can keep the moistening no water layer in furrow face.To ensureing that the paddy rice moisture-sensitive phase is not in life coerced because of lack of water, can ensure that again soil aqueous vapor balances, being beneficial to health of root growth.
" dry wet health care ": the Qi Suizhi maturing stage keeps ditch-water continuous, must guard against and cut off the water supply too early, does yellow maturity to rice strain is blue or green, does not tall and straightly fall, full seed during results.
Chinese milk vetch has another name called Astragalus sinicuses, Chinese milk vetch, grass seed, originates in China.Happiness warm and moist condition, has certain tolerance to cold, and Astragalus is annual or get over year sward basis, important green manure, feed dual-purpose crop.Because Chinese milk vetch nutrient content and feed value are all higher, so southern china is used as rice field green manure in winter plantation.Chinese milk vetch every mu fresh weight generally can reach 3000 ~ 3500 kilograms, converts every mu and produces 15 kilograms of N, 3 kilograms of P
2o
5with 12 kilograms of K
2o, its NPK output in theory substantially can meet one season high-yield rice fertilizer requirement.But the nutritive element slow releasing of organic green manure, timely modulability supplementation administration chemical fertilizer of still needing.Wet kind of the culture technique of paddy rice " furrow ridge formula ", advocate and supplement wean 10 kilograms, fertile urea after planting 7 ~ 10 days (about the paddy rice 3 leaf phase) every mu, sow 20 ~ 25 days (about paddy rice 5-7 leaf phase), every mu of supplementation administration 10-15 kilogram of urea, 20-30 kilogram potassium chloride, 15-20 kilogram superphosphate
Beneficial effect:
The present invention adopts green manure to increase soil fertility, and the wet kind of cultivation of furrow ridge formula, effective Limiting Irrigation water, with stable yields abridged edition for core, is aided with water saving and increases soil fertility as target, realize the energy-saving and environmental protecting of rice technology, ensure grain and ecological safety.
