The technical solution adopted for the present invention to solve the technical problems is: with farmyard manure is main fertilizer, in the rice field, put duck in a suitable place to breed and play the effect of loose seedling root, promote the development of rice shoot root system, the duck excrement is effective organic manure simultaneously, duck is very big in the effect that Tanaka destroys plant diseases and insect pests in addition, and the consumption of chemical fertilizer and agricultural chemicals is used in a large amount of minimizings.Realized that green rice is of fine quality nuisanceless, reduced harm, realized high yield, increased peasant's income human body.

Effective effect of the present invention is can reduce the consumption of using chemical fertilizer and agricultural chemicals in a large number by the present invention, cultivation of realization high-grade rice and growth.Overcome the defective of using chemical fertilizer and agricultural chemicals that human body is endangered, while green rice nutrient component height, people are to its prestige height, and price is also high, increases the peasant economy income significantly, is the promotion project that country has design for development.

Description of drawings

The present invention is further described below in conjunction with the technological process in the accompanying drawing.

Technological process is among Fig. 1:

Seed selection-bubble kind-whole seedling pond-sowing-seedling cultivation-lifting-choosing system Honda-rational close planting-plant-field management

Embodiment

Technological process with reference to the accompanying drawings illustrates respectively.

1. seed selection

With selected high-quality seed rice, in the natural wind of 3-4 level or blowing under the choosing of Yang Zhongji, remove the not full grain of rice in leeward, then seed rice is put in the cylinder of 5% limewash, the capacity of limewash is 3 times of seed rice quality, manually stir with waddy, soak after 20 minutes, the not full grain of rice that swims on the water surface is removed, pull the full grain of rice out, use flushing with clean water, remove the limewash that attaches on the grain of rice.

2. bubble is planted

Seed rice after cleaning is placed in the cylinder or soaks after 24 hours in the bucket and pull out, do not have pour into when dripping take off with hand in the bucket flat, lotus leaf or rush bag on the upper cover.Sprayed water smoke at interval in 4 hours, turn seed rice by hand, continue after 6-7 days, can move when 1 millimeters long is germinateed at the seed rice tip and broadcast the seedling pond.

3. whole seedling pond

Ground, seedling pond must flatten wide 1 meter, the long 5-6 rice in single pond.Miao Chi paves with plastic film, sprinkles the humid soil that 3 centimeters thick farmyard manures and dried fine earth and ash stir on plastic film uniformly, and its humidity hand is grabbed agglomerating, loose naturally being advisable when unclamping.Dig dark 15 centimeters, wide 20 centimeters ditch around the Miao Chi, spread 1 centimeter thick drystone ashes in the ditch, prevent that insect such as earthworm from entering Miao Chi and damaging the rice shoot root system.

4. sowing

After the Miao Chi arrangement specification of symbols, the seed rice that germinates is sprinkled into Miao Chizhong equably, general density is that every square centimeter of 6-7 grain is moderate, accomplishes light seeding, even broadcasting.Light seeding, even broadcasting can make the rice shoot individuality that uniform standing area and space are arranged, and make the rice shoot ventilation and penetrating light, increase sunshine, improve the photosynthetic rate of rice shoot.This increases nutrient accumulation to promoting the balanced growth of acrial part and under ground portion, the population growth neat and consistent, and reducing interindividual variation all has tangible effect.Have only light seeding, spare and broadcast, could really reach the purpose of the strong seedling of tillering, after planting must in time press and plant, be pressed in above the seed, do not reveal seed and get final product with the fine particulate farmyard manure.

5. seedling cultivation

The normal growth phase of rice shoot is about 24 days, and general 6-7 leaf is transplanted to Honda.The tradition seedling growth phase is 30 days.Soil moisture will remain on about 75% among the Miao Chi.

1 leaf is before 1 heart stage, based on moisture management, mainly with vaporific moistening soil, promotes to take root upright seedling, also helps suppressing harm such as Homonemeae, earthworm and prevents the infection of pythium rot, bacterial leaf-blight germ.

1 leaf is between 1 heart stage and behind 1 leaf, 1 heart, sprays with the globule to keep the moistening of soil, promotes that the rice shoot root system is healthy and strong to grow.

On Miao Chi topdressed, based on farmyard manure, earlier light back was dense, from less to more, and " having many meals but little food at eath ".Before transplanting 3-5 days, the heavy dressing fertilizer of standing up.

6. lifting

For shoot transplanting equipment is turned green soon to this Tanaka, early balled transplanting is wanted in recovery, and band fertilizer is gone to the field.Therefore the soil of Miao Chizhong must be shoveled out with rice shoot during lifting, be placed on the plank, discharge farmyard manure, phosphate fertilizer and potash fertilizer on the plank, these fertilizer are attached on the rice shoot root soil.

7. choosing system Honda

Choosing system creates that the water conservancy condition is good, irrigation and drainage convenient, sun-drenched first-class fertility field, after the ploughing and weeding that discharges water, the colony in about one month duck age is placed on this Tanaka removes insect pests such as earthworm, reduces transplanting the damage of back rice shoot root system.

Make the field piece and will use sufficient base manure according to field block manure power situation, base manure will be executed a certain amount of quick-acting fertilizer again based on farmyard manure, turns green fast for rice shoot and creates a good soil environment.

8. rational close planting

Rational close planting, increase the basic seedling amount on the unit are, though the individual plant The mean tillering has been lacked, the individual plant number of productive ear is also corresponding to have lacked some, because the basic seedling amount of inserting is many, so the total number of productive ear in full field greatly increases, suppressed tillering of later stage simultaneously, heading relatively concentrates, neat, shortened from time of the here fringe of beginning fringe, under the situation of flower synchronization, be very favourable to improving output.General seeding row spacing adopts 12 centimetres of 12 cm x.

9. plant

The rice shoot of Honda will adhere to accomplishing shallow slotting, even inserting, and inserts straight, slotting steady.The degree of depth of rice transplanting is about 1.8 centimetres, with floating be principle, because of tillering node between 1.8-2.3 centimetre, shallow slotting ventilation is good, soil temperature is higher, low joint potential energy is enough sprouted to become to tiller, rice shoot is sent out early, sends out soon, it is many to tiller.And tillering of these low joint positions takes place early, and vegetative growth phase is longer, and blade is more, thereby seedling growth is sturdy, heading in good time, big panicle many grains per panicle is very beneficial to improving output.If rice shoot is inserted dark, situation is opposite fully.Tillering node is in poor aeration, nutrition condition is poor, temperature is low soil layer, tillers and do not send out, will lean on tillering of Gao Jiewei in low joint position.So the seedlings of cereal crops just for a long time send out to get up, the quantity of tillering is few, and the time is slow, and is of poor quality, and heading is late, the result must be fringe little, less, yield poorly.

10. field management

Getting hold of field management, is the important step that realizes good quality and high output, is the key that obtains high yield.

Concrete measure is: early execute the heavy dressing tillering fertilizer, the diligent filling of shallow water urgees to tiller.Insert the back and chased after fertilizer for the first time in 4-5 days, finish to topdress for twice in 18 days and weed the fields.Early stage, topdressing amount should reach about 80% of total topdressing amount.Fertilising mainly makes graininess with animal manure and nitrogen, phosphorus, potash fertilizer rationally are used.

In the time of seedling growing 15-16 days, the field is put the group duck weeding about 0.5 kilogram, loose seedling root, fertilising in a suitable place to breed.Specific practice is: shallow water is answered in the field, depth of water 1.5-2 centimetre, and every mu is sprinkled into through rose 15 kilograms of wheats of bubble, then the group duck is put in the paddy field, and duckbilled stretches in the soil He in the seedling root and eats wheat, the effect that has played effective pine stump, taken off the seedling root.Simultaneously, the duck excrement has been made the once fertilization effect of high fertilizer efficiency, promotes the quick growth of rice shoot root system, has increased the function of tillering.

Rice shoot entered after mid-term, and control measures are transferred fertilizer based on water with water, suitably the open field.Particularly execute ash, better effects arranged strong bar is solid.This moment is nitrogen fertilizer application again, in order to avoid cause remaining green when it is due to become yellow and ripe excessive growth, postpones the florescence, and easy sick worm reduces ripening rate.Field management this moment suitable " doing wet ".Just at this moment, sick worm is taken place more, strengthen control.The group duck is placed Tanaka eliminate disease over 1-2 days, because of the group duck can eat up most of insect Tanaka, in addition because the smell of duck excrement and duck body can suppress the generation of damage by disease and insect.Simultaneously can also carry out good florescence regulating action.

Later stage is a heading flowering period, and field management enters attacks a stage, can be described as the final stage of capturing high yield this period.Main direction is to improve outcrossing seed-setting rate, and measure is to strengthen removal of impurities, runs the field water layer well, prevention and elimination of disease and pests etc.
