Improve the percentage of earbearing tiller, shorten early rice period of duration, favourable Oryza sativa L. Sustainable high yield and rice field, water source environment protection, promote Rice Cropping to
Efficiently, accurate and sustainable agriculture direction is developed.
The technical solution used in the present invention is:
A kind of fertile implantation methods of Indica Rice joint by artificial regulatory colony, when rice transplanting or throwing are planted, suitably increases
Add Honda Seedling number, artificial regulatory Oryza sativa L. early stage colony, saves dose, increases rice yield；Before described artificial regulatory Oryza sativa L.
Phase, colony was as follows with the relation saving dose:
Y (a-b) × [0.57 ‰+(0.5-X) ‰]
In formula, Y is for can save dose, unit K g；A is rice seedlings number after artificial regulatory, and unit is Seedling/mu；B is existing
The Seedling number of technology, unit is Seedling/mu；X represents the size of rice varieties tillering ability, is divided into 5 according to rice varieties tillering ability
Individual grade, 0.1 grade represents the kind that tillering ability is the strongest, and 0.3 grade represents the kind that tillering ability is stronger, and 0.5 grade represents tiller

0.1 or 0.3,0.5,0.7,0.9.
In technique scheme, after artificial regulatory, the difference (a-b) between rice seedlings number and prior art Seedling number controls
2000 5000 Seedlings/mu is advisable.
In technique scheme, it is preferable that while using the inventive method to execute ear manuer, carry out Deep irrigation and Pest organism
Evil preventing and treating.
In technique scheme, described fertilizer is that purity nitrogen is fertile.
The inventive method follows the dynamic principle of management of " selection kind promotees tiller, final singling Shuo Jian colony, joint nitrogenous fertilizer increase benefit ",
It substantially includes the content of following 4 aspects: 1. rice varieties selection, 2. increase Honda basic seedling amount, 3. by above-mentioned
Formula accurately calculates savable fertile amount, 4. Deep irrigation, timely prevention and control pest and disease damage.
Rice seedling to tillering regularity colony set up significant to the formation of later stage high yield, this period Oryza sativa L.
The absorbtivity of Fertilizer nutrient is accounted for the 26%-30% absorbing total amount the time of infertility, main is supplemented by base manure and tillering fertilizer.Honda base
This Seedling number number and the quality of seedling quality be to determine the key factor of colony quality in seedling stage, for high yield can be constructed in seedling stage
Colony, Rice Cropping person's conventional process adds fertilizer exactly, promotees tiller with nitrogen, by fertile upgrading.Though using the method can realize Oryza sativa L.
High yield, but if things go on like this, it is serious that the excess of fertilizer uses not only waste, but also pollutes rice field and water source.Artificial tune
The Oryza sativa L. fertile implantation methods of joint of control colony utilizes the principle of " with Seedling for nitrogen, increase tiller by Seedling ", according to breediness, is counted by precision
Calculate, suitable increase Honda Seedling number, so that the most single the depending on of the formation of yielding Populations enriches fertilizer, but more
Relying on and increase Honda basic seedling amount, the method is not only greatly reduced ineffective tillering, improves the percentage of earbearing tiller, is also effectively increased nitrogen
Fertile utilization rate and rice quality.
On the basis of Honda increases identical basic seedling amount, if the tillering ability of rice varieties is stronger or weaker, then may be used
The fertile amount saved is correspondingly improved or reduces, and the tillering ability of the rice varieties i.e. chosen seeds often shifts to an earlier date (or reduction) 1 grade, can
The fertile amount saved the most correspondingly increases (or minimizing) Honda and increases the 0.2 ‰ of Seedling number.Such as, if the stronger product of tillering ability
Kind, tradition Seedling number is 18000 Seedlings/mu, is 21000 Seedlings/mu after artificial regulatory, then can save fertile amount=(21,000 18000) ×
0.57 ‰+(0.5 0.3) ‰) ］=2.31kg purity nitrogen/mu；
Additionally, rice tillering contains phase leaf transpiration amount greatly, metabolic is vigorous, therefore needs Deep irrigation；Simultaneously as should
Period, colony's permeability was poor, will carry out disease, worm, the forecast of crop smothering and preventing and controlling in time, it is ensured that rice high yield high-quality.
Compared with prior art, the invention have the benefit that
First, prior art is mainly by blindly adding tillering fertilizer structure Oryza sativa L. early stage yielding Populations, and its topdressing amount is difficult to
Grasping, often lead to postpone vegetative growth phase, ineffective tillering increases, and seedling quality is the highest.This practical technique is according to rice tillering
Phase informative population Formation and characteristics, is increased transplanted seedling number by artificial and reduced fertilizer amount, ineffective tillering being greatly reduced, improves
The percentage of earbearing tiller；
Second, different rice varieties tillering abilities are different, and prior art is strong and weak regardless of kind tillering ability, thousand times one
The same recommended rate of fertilizer application of use of rule, does not scientifically propose rate of fertilizer computational methods accurately according to breediness.Should
Practical approach by being divided into 5 tillering ability rank order by rice varieties, and combines manually increasing Seedling regulation and control colony, effectively, closes
That manages decreases fertilizer amount；
3rd, this practical approach, while being effectively improved utilization rate of nitrogen fertilizer and rice quality, is also effectively shortened early rice
Period of duration 3-5 days, has striven for the quality time for double rush for harvesting and sowing busy farming season；On the other hand, this practical approach is ensureing yield and quality
On the premise of decrease fertilizer amount, the protection to the environment such as rice field, water source is significant.
In a word, by rice cropping experience for many years, and with a large amount of field tests as foundation, for current fertilizer blindly excess
The problem used, the present inventor proposes a kind of fertile implantation methods of Indica Rice joint by artificial regulatory colony.Should
Method has science, reliability and safety, Oryza sativa L. Sustainable high yield and environmental conservation is all had important guiding effect, helps
Develop to direction efficient, accurate, sustainable agriculture in promoting China's Rice Cropping.
