Description
Technical field
The invention belongs to field of agricultural production technologies, and in particular to a kind of rice high yield section fertilizer implantation methods.
Background technology
Modern rice high yield plantation science it has been determined that rice yield per unit area depend on effective panicles per unit area,
Number of grain per ear and mass of 1000 kernel, three are referred to as rice yield constituent element.Between three factors, there are delicate restrictive function,
In Rice Production, it is necessary to coordinate the correlation of three factors so that the product maximum of three factors is possible to realize rice
High yield.
Under normal conditions, since the degree of stability of three factors is different, there is also poor for their actual influences to yield
It is different.In contrast, grain number and grain weight more stable (luffing is smaller), and spike number is then easier to change.Therefore, in Rice Production,
On the premise of grain number and grain weight is not significantly affected, it is rice height to obtain maximum number of productive ear (Reasonable population structure) as far as possible
The key of production.Rational group is much, how to build be the problem of rice high yield technical system is most crucial.
Traditional Rice Cropping theory thinks that rice high yield to be realized must early tiller, more tillers required for reach high yield
Spike number, that is, promote tiller be realization high yield premise.However, rice tillering is not unlabored into fringe,
Process is influenced by many factors, such as kind, date of seeding, density, transplant depth, water layer thickness, nutritive water equality.In these factors
In, trophic level is unquestionably most basic condition, because without most basic material guarantee, all measures are all to be difficult
It plays a role.Rice science research has illustrated, and rice wants tiller, in vivo Nitrogen Nutrition should more than 3.5%,
Otherwise, tiller will not smoothly occur.But rice seedling root system is few, absorbability is weak, relies solely on normal soil nutrient supply
It is the nitrogen nutrition demand that can not meet rice tillering, fertilising is just into the unique selection for promoting tiller.So existing rice
High yield it is theoretical it is believed that the method for capturing high yield should be apply base, fetilizer for tillering, nitrogen content in Rice Seedlings body is increased to
More than 3.5%, to increase available tillering, otherwise, spike number is inadequate, can not realize high yield.The emphasis of this Rice Cropping theory
It is " realizing high yield to promote individual structure yielding Populations ", corresponding measure is heavy dressing base, fetilizer for tillering, thus carries and significantly " pull up seedling
Encourage " the characteristics of.Under this theoretical direction, the phenomenon that Rice Cropping density is relatively low, chemical fertilizer overuse, is universal (usually
In the case of, per 667m2, Nitrogen Amount few about 10~12kg, typically about 15kg or so, highest is even up to 20~
24kg).This it is theoretical with technology there are the problem of, it is most important to have：
(1) underestimate the Nitrogen releasing amount of soil, ignore being acted on for nitrogen for soil.Since density is low, rice root quantity is few,
Small with soil contact product, the nitrogen quantity absorbed from soil is also just few.This can give people one illusion, i.e., no matter soil has
It is much to imitate Nitrogen Determination value, soil does not all provide how many nitrogen, and the application of nitrogenous fertilizer need not consider the confession nitrogen status of soil.It is this
Phenomenon all largely exists in scientific research or production practices.
(2) over-evaluate utilization rate of nitrogen fertilizer, weaken the problem of excessive applied nitrogen triggers.After fertilising, in rice aerial
While amount increases, underground increment also can accordingly increase, and especially early period, dose was big, and underground part increment increase is brighter
Aobvious, the nitrogen quantity that root system is absorbed from soil necessarily increases, even if the utilization rate of nitrogen fertilizer calculated using minusing is caused to exclude
The priming effect of instant nitrogenousfertilizer, it is still higher.This causes many people to believe, under existing situation, the method for application of nitrogenous fertilizer is
Acceptable.However, it in the recent period, uses 15NTracer study the result shows that, utilization rate of nitrogen fertilizer with amount of nitrogen increase and reduce, it is preceding
Phase fertilizer ratio is bigger, and utilization rate is lower.Illustrate that traditional nitrogen management pattern is implicitly present in problem.
(3) nitrogenous fertilizer is excessively applied, and causes the unreasonable application of phosphorus potash fertilizer.Although most people is thought, soil quick-effective phosphor potassium
Measurement result to guidance fertilising be of practical significance, but soil quick-effective phosphor potassium measurement result very it is high still apply phosphorus potash fertilizer the phenomenon that
Also it is very universal.To find out its cause, still because excessive applied nitrogen causes serious nutrient imbalance, in order to correct nutrient injustice
The adverse effect of weighing apparatus can only be adjusted using phosphorus potash fertilizer, phosphorus potash fertilizer application occurred and also surveyed substantially without considering soil quick-effective phosphor potassium
The strange phenomenon of test result.
(4) rice redundancy growth increases, and is unfavorable for the performance of variety yield potentiality.Existing research illustrated already, used
Downward trend is presented in traditional Rice Cropping pattern, harvest index.The basic reason for causing this phenomenon is base fetilizer for tillering amount of application
Greatly, nutrient growth is excessively prosperous, and the dry matter of accumulation early period can not be converted into the yield in later stage；Secondly, later stage trophosome
Vital movement is also required to consume a certain number of dry matters, so, showing redundancy growth increases, and influences variety yield potentiality
It plays.
In conclusion the planting technology that current Rice Production generally uses, is difficult real although realizing the high yield of rice
The efficient utilization of existing nutrients resource, there are more serious nutrients resource waste and problem of environmental pollution, be unfavorable for society can
Sustainable development, it is necessary to be changed.
The content of the invention

Advantages of the present invention：
1. the present invention difference most basic with traditional rice high yield implantation methods is the utilization to rice tillering.Traditional water
Rice high yield technique will utilize rice tillering, and it is the key technology that it realizes high yield to promote tiller technology.The present invention and tradition side
The theory of method is significantly different with technology.Conventional method reaches high yield using agronomy demand as foundation, by promoting seedling structure yielding Populations
Spike number, early stage amount of nitrogen usually substantially exceeds the requirement of paddy growth so that rice strain over growth, this had both been caused each other
Keen competition (competition between rice strain and between tiller), the later stage is also required to heavy dressing to maintain the metabolism of rice strain.This side
Method, it is necessary to which high yield could be realized by relying on a large amount of nutrient supplies, and the contradiction of high yield and nutrition efficient is difficult to reconcile, the result is that resource is unrestrained
Fei great, agricultural non-point source pollution are serious.The method of the present invention is using the nutritional need that rice individual growth is developed as according to (rice individual is raw
Growing the nutritional need developed is：The uptake of nitrogen, transplanting~jointing are about the 30% of gross absorption, and jointing~heading is about
40%, about 30%), by dense planting heading~maturation builds yielding Populations (yielding Populations size, specifically namely spike number is more
It the problem of few, is mainly obtained by experimental study.At present, it is believed that under usual conditions, rice will obtain high yield, often
667m2About need 25 universal effect fringes.By this standard, row hill spacing 25cm × 5cm is planted in this method design, per 5 plants of cave, then per 667m2Always
Seedling number is 667 ÷, 0.25 ÷, 0.05 × 5 ≈ 26.6 ten thousand, reaches yielding Populations requirement), do not promote seedling demand, the supply of nutrient is only
Ensure individual normal growth and development, thus only apply chemical fertilizer in right amount and make base manure (dose need to according to rice individual early stage
Nitrogen quantity and the content of inorganic nitrogen in soil determine.Under normal conditions, it is averaged with every 667m2 production paddy 600kg, per 100kg paddy
Rice nitrogen requirement is needed before nitrogen 2.5kg, jointing to account for average content 10mg/kg of total nitrogen requirement 30% and inorganic nitrogen in soil etc. to estimate
It calculates, then 600kg rice yields always need the 100 × 2.5=15kg of ÷ of nitrogen=600, and amount of nitrogen sucking is 15 × 30%=4.5kg before jointing,
Nitrogen rate provided by soil be 10 × 0.15=1.5kg, Nitrogen Application amount=rice absorbing amount-Nitrogen rate provided by soil=4.5-1.5=3kg),
Do not apply tillering fertilizer.The key of this method is " to build yielding Populations with dense planting, do not apply tillering fertilizer, maximal efficiency phase (i.e. rice institute
The nitrogen of absorption can play that time of its maximum yield potential, that is, jointing stage) it applies fertilizer and strives grain number, heading, grouting
Phase fertilising increase grain-weight ".This method, each stage of the entire growth and development process of rice all need not excessively apply fertilizer, greatly
The big fertilizer amount that reduces is (per 667m2, 5~8kg of Nitrogen Application amount), and the restriction between spike number and grain number and grain weight is smaller,
Be conducive to the rice high yield under the conditions of weight-reducing.
2. the present invention payes attention to the burst size of soil nitrogen during paddy growth, this and the nitrogen pipe in current Rice Production
There are a great differences for reason.At present, Rice Production easily causes nitrogen unrestrained wholly or substantially without considering soil nitrogen release conditions
Take.In the agricultural production of reality, many crop productions are all so.It is presently believed that soil nitrogen, which is crop, absorbs nitrogen
Important sources, as long as this part nitrogen is made full use of, you can reduce nitrogen fertilizer amount on the premise of rice yield is not reduced.
Therefore, it is necessary to pay attention to the effect of soil nitrogen and accurately grasp soil nitrogen burst size as far as possible.The definite and nitrogen of dose
Fertilizer, which is planned strategies for, must take into full account the supply situation of soil alkali-hydrolyzable nitrogen and inorganic nitrogen.
On the premise of 3. the present invention can even increase production ensureing high yield, fertilizer amount is greatly reduced, really realizes water
Rice high yield and high-efficiency nutrient resource utilization reduce the wasting of resources, prevent the pollution of the environment, and ensure the sustainable development of society.
