Description

Rice seedling small plant combination transplanting method

Rice seedling small plant combination transplanting method of the present invention relates to the new rice transplanting method of a kind of paddy rice.

Traditional rice transplanting method all is that many strains rice shoot is combined into a root and stem of certain plants, inserts simultaneously in the lump down, though this rice transplanting method helps to improve rice transplanting speed, be unfavorable for the development of rice shoot root system, be unfavorable between the rice shoot strain ventilated, influence rice shoot and tiller and send out a root and stem of certain plants, thereby influence the rice high yield stable yields.

The object of the present invention is to provide a kind of rice transplanting method of the obvious effect of increasing production of having improved.

Rice transplanting method of the present invention is that the density of transplants seeding row spacing is generally 6 * 7 cun to 6 * 8 cun.During rice transplanting, every root and stem of certain plants can be inserted 2 strains, 3 strains or 4 strain rice shoots, and several strain rice shoots of every root and stem of certain plants will distinguish a strain one strain and insert down, and the interval is about 2 centimetres each other.When every root and stem of certain plants was inserted 2 strain, rice shoot is alternate 2 points that are each other; When every root and stem of certain plants was inserted 3 strain, rice shoot was each other alternate triangular in shape; When every root and stem of certain plants was inserted 4 strain, rice shoot is the alternate square that is each other.Can't scheme to save trouble soon, several strain rice shoots one of every root and stem of certain plants are following inserting simultaneously.What will decide according to rice varieties and fertilizer and water condition concrete every root and stem of certain plants rice transplanting.When general cross kind or fertilizer and water condition are better, can be suitably rarer, every root and stem of certain plants can be inserted the 2-3 strain, when relatively poor for conventional variety or fertilizer and water condition, can be suitably closeer, every root and stem of certain plants can be inserted the 3-4 strain.The temporary called after rice seedling small plant combination transplanting method of this rice transplanting method.Adopt this rice transplanting method, greatly promoted the development of rice shoot root system, improved Partial little climate environment between the rice shoot strain, the field is ventilated good, turns to blue or green fast after rice shoot is inserted, and root of hair early and many, tiller early and soon seedlings of cereal crops stalwartness, percentage of earbearing tiller height, both help to promote ontogeny, be conducive to again the highest seedling number of control, and can effectively coordinate the contradiction of individual and group, be convenient to field management, reduce the generation of disease and pest, fringe is many, fringe big, grain is full, the purpose of stable high yield thereby reach.General per mu yield can reach about 1000 kilograms, can extensively be suitable for the paddy rice producing region and be applicable.It is important to point out, adopt the seedling small plant combination transplanting method, because severals strain rice shoots of every root and stem of certain plants will be distinguished an alternate strain one strain and insert during rice transplanting, seeming at first view wastes time and energy.Actually this is not so, rarer because of the density of this rice transplanting method own, and seedling is plugged for disposable, do not resemble existing " two two is big " cultivation, two sections seedling, posts the rice transplanting seedling, former root and stem of certain plants transplanting etc., and rice transplanting comparatively bothers.Particularly the field is ventilated good, and the seedlings of cereal crops later stage is easily controlled seedling, the growing way stalwartness, and relative disease insect pest generation is few, and the field is easy to management, and is therefore as a whole still comparatively time saving and energy saving, and its profit is much larger than " fraud ", and is especially true as remarkable take effect of increasing production.

For guaranteeing rice seedling small plant combination transplanting method stable high yield of the present invention, it is corresponding plants that to amass wealth by heavy taxation technical essential as follows:

One, cultivates strong seedling.The seedling seed-grain will be basked seeds, chooses seeds, soaks seed and be sterilized.Water seed soaking must not surpass 30 ℃, must not be above 40 ℃ during warm water vernalization.Want the finishing rice seedling bed, use sufficient base manure, 20 kilograms of nitrogen-phosphorus-potassium compound fertilizers can be executed in common every mu of rice seedling bed, or suitable fertilizer with it.Begin sowing in good time, generally pass through 12 ℃ as sowing safe period so that mean daily temperature is stable.Should note " cold period " seed soaking, " the warm head of cold tail " robs fine sowing.After planting to strengthen management, note topdressing, and carry out work such as weeding, deinsectization, irrigation and drainage.The railway carriage or compartment face will often keep the shallow water more than 5 centimeters, and heavy rain is wanted waterflooding, in order to avoid break seed-grain.Can insert kind when rice shoot is tillered to the 3-5 leaf, seedling age is preferably 30 days, generally must not be above 40 days.

Two, meticulous whole ground.It is in good time, meticulous and smooth that preparing soil in rice field will be accomplished, earth is soft, and ridge must not leak.Use sufficient base fertilizer, the rice field fertility substantially can divide, in, differ from three kinds of grades.50 kilograms of nitrogen-phosphorus-potassium compound fertilizers are executed for general every mu in the rice field of medium fertility, or with 50 kilograms of suitable fertilizers.Base fertilizer will be appended in the rice field of fertility difference more, does not apply fertilizer in the very good rice field of fertility.In a word, fertilising is wanted suitably, so as not to remaining green when it is due to become yellow and ripe late-maturing, affect high yield.

Three, shallow rice transplanting seedling.Guarantee that shallow slotting condition is, whole ground will put down, rot, spares, only.The shallow slotting degree of depth of early rice was covered seedling head mud for well with mud scum, and late rice can be controlled in 1 cun.Rice transplanting must be carried out according to above-mentioned " seedling small plant combination transplanting method ".

Four, intertillage is topdressed.Inserted the back 20-30 days when rice shoot, in time intertill and topdress, tiller urging.Execute 20 kilograms of 15 kilograms in urea or composite fertilizers for general every mu.Fertilising should be noted according to the paddy growth rule principle of " front heavy ", " middle control ", " rear light "." front heavy " be exactly from play the Sheng phase of tillering wholely, take basal dressing as main, fertilizer is main, early stage tillering fertilizer is auxiliary, with the short healthy tree of tillering, total its dose of this one-phase should account for the 80-90% of dose." middle control " just refers to that late tillering state arrives the joint phase of dialling, general nitrogen fertilizer application and enrich a small amount of phosphorus, potash fertilizer not, and be aided with the draining dry field, with short stiff rod diseases prevention." rear light " just refers to boot stage to the pustulation period, and this one-phase is on the basis of dry field, and is light if backwater posterior lobe look obviously moves back, and the performance fertilizer deficiency of can not naturally turning green should take the circumstances into consideration to impose foliage fertilizer.

Five, science Guan Shui.Turn to blue or green in rice transplanting, will keep the slime water rice transplanting tillering stage, shallow water is urged tiller.Ear differentiation should be take dry field as main to boot stage, and shallow water is filled with at the interval.Water thoroughly will be drained before the dry field, Tian Yaochong shines, and is generally 7-10 days, and the cold immersed field can be shone more than one month.Late growth stage of rice will be accomplished moistening guarantor's booting, and half cun water is taken out Qi Sui, does the wet grouting of protecting.Particularly pouring water behind the dry field preferably will often keep running water to fill with the field, do not worry the fertilizer of wandering away.Because only have this moment running water to fill with the field, could reach better reduce phlegm and internal heat, the purpose of diseases prevention worm, the root that relaxes, strong bar, strong seed.Should cut off the water supply in preceding 7 days in harvesting.

Six, insect pests.The rational application of fertilizer, science Guan Shui accomplish that early stage, the seedlings of cereal crops did not hail, and the later stage is not remaining green when it is due to become yellow and ripe again, and mid-term, in time saturating yellow strong bar was disease-resistant pest-resistant prerequisite.Paddy rice is not generally wanted the dispenser desinsection heading stage in seedling phase and flowering.General control worm for the first time about rice seedling bed seedling growth to 25 day; Control for the second time worm after the rice transplanting of land for growing field crops 10-20 days; Control for the third time worm and carry out in conjunction with intertillage, method is water to be put dried, with rod the small worm on the leaf, moth is all shaken to cause drop Tanaka, preferably tramps with one's feet under mud, can every mu mixes 2.5-3 kilogram furan Nandan in conjunction with topdressing simultaneously and executes down in the lump, mainly to prevent and treat the latent fly of rice straw; Controlling worm the 4th time should be after dry field be poured water, and carries out before the flowering heading.Special circumstances should be accomplished the in time anti-worm of curing the disease.

Embodiment: since nineteen eighty-three, the inventor adopts rice seedling small plant combination transplanting method of the present invention in this village and own farmland covered by contract, and its area size has 0.12-1.20 mu not wait, and stable high yield is every year amounted to per mu yield and can be reached more than 1000 kilograms.Wherein nineteen eighty-three is jumped 0.8 mu of field of plantation, stone village in Huanglong town, Xinning County, and real 1210 kilograms of the gulches of receiving are amounted to 1517.7 kilograms of per mu yields.Compare test in 1997 the odd amount in addition to the round number field at 0.1 mu of area (little place names), wherein 0.05 mu is adopted seedling small plant combination transplanting method, receives 50 kilograms of gulches in fact, and second half 0.05 mu adopted the conventional cultivation method, but only receives 25 kilograms of gulches, and the two output differs half.Inventor in 1998 in above 0.1 mu odd amount in addition to the round number field, all adopts rice seedling small plant combination transplanting method again, and paid gulch 105 kg is amounted to 1050 kilograms of per mu yields.
