Description
Technical field
The present invention relates to agricultural fertilizer production technical field, more particularly to a kind of rice fertilizer inhibiting ineffective tillering.
Background technology
Only angle gold lactone in Levant Cotton Root juice initially by separating, it is considered to be what unipods seed metallization was sprouted
Stimulant.Its another effect is exactly a kind of essential chemistry coupled with arbuscular mycorrhizal fungi as plant rhizosphere
Signal, other than above-mentioned effect, witchweed lactone or its metabolite can also be with as a kind of novel plant hormone
Inhibit plant branching.
The standard of rice jointing be stalk base portion first extend panel length reach 1~2cm (dwarf type kind reaches 1cm,
High stalk type kind reaches 2cm), when field has 50% plant to reach jointing standard, as jointing stage.Rice internode elongation is certainly
It is sequentially carried out one by one on down, extends general 4~7 of internode.Jointing stage is all gone out in rice formalness and internal physiological
The period of existing great change.Corresponding field management is taken according to the Morphology And Physiology changing rule of rice jointing stage in cultivation
Measure lays sufficient fringe, big fringe basis for high yield.
Rice stem is using jointing as boundary to the nutrient supply of its tiller.It is main in the case where growth conditions is suitable
Stem has more nutrient supply tiller growth before jointing, and after jointing, since Leaves on main stem, stalk, fringe mushroom out
Itself needs a large amount of nutrition, will drastically be reduced to the substance supply of tiller, at this moment less than the tiller of three leaves due to can not
Individual absorption nutrient can stop growing because of subalimentation, become ineffective tillering.The tiller root system for reaching three leaves being capable of absorbent earth
Earth nutrient, and the growth and development needs of itself can be supplied by photosynthesis with enough leaf areas, it has eventually become
Imitate tiller.Therefore, according to leaf tiller Synchronous relationships, tiller must extract out for 15 days or so before stem jointing, could be in stem jointing
When reach three pieces leaf, and then it is effective fringe to develop.Tiller occurs more early, and in stem jointing, the number of blade is more, and root system is also more
It reaching, the ability of autotrophy is stronger, and percentage of earbearing tiller higher, spike of rice also can be bigger, so promote tiller early growth and quick tiller in production, it is more
Strive for that the tiller of low tiller position occurs, be to improve rate of tillering panicle, ensures the key of sufficient fringe.
Jointing, the field management in boot stage are adjusted to by promoting the early field management measure for sending out, striving more fringes by tillering stage of turning green
Field management technology centered on promoting to strengthen stalk, strive big fringe, does a good job of it dry field moderately and at the right moment, sees that seedling ingeniously applies the measures such as ear manuer, control tiller,
Strong stalk, promoting root growth, disease-control increase Floret differentiation number, reduce grain husk flower degeneration number, reach that stalk is strong, fringe is big, the high yield target more than grain.
There is research and utilization growth regulator adjusting and controlling rice tillering on Production of Large Fields at present, but these grow
Conditioning agent is mostly the promoted types hormones such as gibberellin (GA3), in enhancing rice apical growth advantage, inhibits the same of tiller generation
When, blade will be generated, leaf sheath, internode shorten or it is elongated, even change the side effects such as Rice Growing process, increase runt seedling or fall
The risk of volt.Under the premise of not influencing rice normal growth, how to efficiently control ineffective tillering and have become rice control skill
The difficult point of art research and application, there is an urgent need to explore the new way of the adjusting and controlling rice tillering unrelated with apical growth advantage.
In addition, the management of rice jointing stage at present needs to draft Elymus excelsus measure according to the form after rice jointing.It pulls out
After the section phase, there is " three become " in rice formalness, and leaf color becomes light green from bottle green, leaf to become upright from hanging down loosely, stem foot
Portion is rounded by flat.If leaf color and it is leaf do not change, illustrate over growth, to take control rich water measure:Do not apply or
Shaoshi ear manuer, weight dry field or multiple dry field make leaf color fade to light green, leaf to become straight and upright, and rice strain growth is delicate and pretty, steadily and surely energetically.
Smoothly occur the field of " three become " to rice formalness after the jointing stage, then cannot control rich water, and will be by normal fertilizer and water management
Dry field moderately and at the right moment is carried out, sees that seedling applies ear manuer.These management are high to the technology and skill requirement of operating personnel, in jointing key
If the phase not correctly according to the growth of cereal crop seedlings control rich water, very likely result in the underproduction, for large area Rice Cropping person this
Complicated operation in one stage is time-consuming and laborious, reduces the economic benefit of Rice Cropping.
