The purport of the application is to increase application rate per acre to promote the quantity of seedling and thus increase its closeness, with each
Kind of technological means reduces tillering tassel, including by artificial method, mechanical method, ecological method make tillering tassel removing or
Natural death forms the yield forming of rice per acre with more main fringe and less tillering tassel.An implementation wherein
In example, control tiller includes dry field, trimming and/or application bio-hormone.The control of dry field mode is used in one of the embodiments,
Tiller processed.And/or tiller is controlled using trim mode in one of the embodiments,.Further, using mechanical trimming side
Formula controls tiller, or controls tiller using artificial trim mode.And/or bio-hormone control is used in one of the embodiments,
Tiller processed.In each embodiment, tiller is controlled to prevent the generation of tillering seedling and keep tillering seedling dead.One embodiment wherein
In, the quantity of the target application rate, that is, seedling is arranged according to the effect of control tiller.The mesh in one of the embodiments,
Marking application rate and controlling the effect of tiller is in positive feedback relationship.Also that is, the more good then target application rate of effect of control tiller is higher,
The more high then specific yield of target application rate is higher, forms a positive feedback effect here, and can generate and preferably repel it
The growing space of the effect of his weed growth, the more high then weeds of target application rate is fewer, the more few then weeds in the growing space of weeds
Less and its growth is by bigger limitation.Therefore, control tiller is one of committed step of the application, and control tiller effect is got over
Good, then yield is higher, this is exceed those skilled in the art unexpected again, and well known to those skilled in the art is traditional
Hybrid paddy rice technology is to promote tillering tassel yield and its contribution rate, I had never expected that whole production could be promoted by needing to control tiller unexpectedly absolutely
Amount.Therefore, antipodal with conventional hybridization rice technology to be, the core technology point of the application is the target application rate increased per acre
To promote seedling concentration, and tiller is controlled, tillering seedling is promoted to wither death, this two technology bindings are implemented, and are formed mutual
The cluster combination technique that can not independently work is relied on, i.e. two technologies must bundle implementation, only implement one therein, then
As a result it will go over to the opposite side.The level that two technologies are implemented is also relevant to technical parameter, such as the technology water of control tiller
Flat height, the then amplitude for increasing application rate can increase, and overall effect of increasing production can be more preferable；If the technology for controlling tiller implements water
Put down low, then for the increasing degree of application rate with regard to smaller, technology yield potential will be smaller.In the experimental plot not optimized completely
In, it is more than 1500 public affairs that the higher level that present techniques are implemented, which can make rice yield especially hybridize the high quality paddy yield of low yield,
Pound/acre, due to being all main fringe, grain homogeneity and quality are all preferable, it is often more important that the rice for hybrid rice
Matter greatly improves.Further, it additionally aids on this basis and realizes that labor cost and other means of agricultural production costs decline to a great extent, and
The facilitation for moving towards fool cultivation is horizontal.
The control tiller includes but is not limited to following several in one of the embodiments:
Control nitrogen phosphorization potassium early period, tillering stage will after nitrogen dressing again；
Dry field controls tiller；
Inhibit tiller using bio-hormone class；And/or
Select the kind of not tiller or few tiller.
The important difference of hybrid paddy rice technology and main fringe advantageous combination technology is to treat tiller problem, is entirely in this problem
Opposite technical concept, for hybrid paddy rice technology in early period since density is very dilute, daylighting is insufficient, causes the waste of sunlight-heat reaources；And
The application is substantially the cultivation technique using main fringe advantage, can make up the heredity of single plant production capacity by increasing seedling quantity
Disadvantage makes the kind of high-quality low yield reach the identical yield level of high-yield variety, thus yield can greatly be cooperated to promote rice
Matter changes original high yield low-quality Hybrid Rice into high yield and high quality main fringe rice, is the advanced planting technology for improving rice matter, is conducive to
Improve the staple food rice quality of broad masses.
Further, control tiller in one of the embodiments, so that when tillering seedling death or before or after, it is described
Oryza plant implantation methods, which further comprise the steps of:, removes defect seedling；Defect seedling is sick and weak seedling in one of the embodiments,.Also that is,
Defect seedling is removed in planting process；Remaining embodiment and so on.Also that is, first a large amount of plantations, then remove some problem seedlings
Son avoids waste photo-thermal energy and fertility.Further, it is sowed in one of the embodiments, using target application rate,
So as at least there are 200,000 non-tiller Basic Seedlings per acre, and seedling closeness is at least 3 times of conventional closeness.A reality wherein
It applies in example, is sowed using target application rate, so as at least there are 200,000 non-tiller Basic Seedlings per acre, and seedling closeness is normal
At least 4 times for advising closeness.
The oryza plant is rice or upland rice in one of the embodiments,.Relative to hybrid paddy rice early period due to plantation
Density is very dilute, and seedling negligible amounts cause sunlight-heat reaources to waste, and each embodiment of the application has been taken full advantage of by increasing seedling quantity
The amount of solar heat of full cultivation phase, improves population photosynthesis efficiency, plays the role of certain effect of increasing production, maximum is that can increase original
The yield of the low yield fine quality rice of this hybridization disadvantage allows broad masses of the people that can be able to eat the higher rice of quality.Further,
When being sowed in one of the embodiments, using target application rate, using short bar seed rice with the sowing of high bar seed rice interval
