Rice growth regulation agent and preparation method thereof
Technical field
The present invention relates to plant growth regulator technical field, and in particular to a kind of rice growth regulation agent and preparation method thereof.
Background technology
Rice is one of cereal crops important in the world, improves the main purpose that rice yield is always rice cropping.
Rice yield=mu spike number × fringe weight, mu spike number are rice mu available tillering, and the influence factor of fringe weight is mass of 1000 kernel and fringe grain
The empty flat grain rate of number, the i.e. grain plumpness of rice and fringe, therefore improve rice effective tillering and grain plumpness and reduce fringe
Empty flat grain rate is to improve the important cultivation step of rice yield.
Rice has shooting property, and rice tillering mostly occurs on the extremely short tillering node of basal internode.Evil position is lower, tiller
Generation is more early, and Cheng Sui possibility is bigger, and this tiller is referred to as effective tillering.The slow high evil position tiller of birth then largely can not
Cheng Sui, referred to as ineffective tillering.Tiller number, sooner or later with the rice transplanting depth, temperature, illumination, moisture, nutrient supply, rice transplanting live
Speed it is closely related, especially rice transplanting live a speed on rice effective tillering influence it is very big, rice transplanting is due to pulling up seedlings and moving
Rice shoot root system sustains damage and environmental change during cultivation, and 5~7 days even longer time root systems are usually required after transplanting can just sprout
New root and then restoration ecosystem are sent, is referred to as period of seedling establishment this period.Start tiller after rice striking root, early, low level point occurs for tiller
Tiller is more, so as to be favorably improved the rice tillering percentage of earbearing tiller, and increases the effective fringe of rice and fringe weight;And rice striking root work is slow, point
Tiller occurs late and effective tillering is reduced, then ineffective tillering increases, and rice yield reduces.Therefore rice Rapid Rooting, quick is promoted
Living is the important means for increasing rice effective tillering.
One of an important factor for rice lodging is the grain plumpness and fringe sky flat grain rate for influenceing rice, has become at present
The most important restraining factors of rice high yield stable yields.Lodging can cause photosynthesis and kernel grouting to stop, and greatly influence rice
The quality of rice, causes the flat grain of empty grain to increase, while is made troubles to harvesting threshing, or even threshing, fringe bud phenomenon occurs, increases rice
Paddy loss late, the underproduction caused by lodging are generally 10~30%, even as high as more than 50%.Rice lodging has two types:It is a kind of
It is that root falls, because paddy soil paste is rotten, or topsoil is shallower, and root system development is bad, takes root shakiness, is occurred by wind and rain invasion and attack flat
Lodging;Another kind is that stem falls, because stalk is high and thin and delicate, Basalinternodelength, can't afford top weight, thus the type that bends
The type that lodges or fracture lodges.Plant height is higher, and lodging tolerance is weak;Plant height is shorter, and lodging tolerance is strong.Therefore, hestening rooting, control
Plant height processed is the main path for solving rice lodging, and improves grain plumpness and reduce the important hand of the empty flat grain rate of fringe
Section.
It is to promote root growth, accelerate the promotion tiller of transplant survival speed and control plant height using plant growth regulator
Important means, it acts on obvious.A kind of prosperous dose of rice promoting root growth control of the inventions such as Zhu Chaoyin(CN106259355A), Feng frequently sends out very much
Bright anti-lodging invigorator formulation for rice(CN1504090A), the imitative inventions of Xie Yan a kind of promotion rice tillering granular preparation
(CN102503692A)A kind of and regulating composition of the prosperous anti-fall volume increase of rice control of the invention such as Zheng Xianfu
(CN102701858A)Deng mainly being taken root by using conditioning agent methyl α-naphthyl acetate, heteroauxin, paclobutrazol, Prohexadione calcium etc.
Rush tiller, control are prosperous anti-fall.
Except conditioning agent in itself, time, dosage and the method that conditioning agent is applied are also very crucial, in Rice Cropping concentration zones
Domain, because fertilization of rice dispenser is inconvenient, cost of labor is high, and peasant household is often carried out after rice transplanting when tillering fertilizer spreads fertilizer over the fields and rush of taking root
The prosperous product of tiller control is used together, and main application method, which has to spread fertilizer over the fields to take root after rice striking root work, promotees the prosperous product composition of tiller control;
Heavy dose of plant growth retardent is disposably sprayed after rice work;Individually multiple spray plant growth accelerator and plant
Thing growth retardant.
However, the prosperous product of rush tiller control of taking root at present is mostly to be simply mixed, causes conditioning agent use to go wrong, should take root
When, is controlled prosperous, and it is prosperous to promote tiller time control, between causing each composition conflict can not only play the work of volume increase so as to damage rice seedlings
With occurring underproduction problem on the contrary.
The mixture not only containing plant growth promoter but also containing plant growth retardent is spread fertilizer over the fields after rice striking root, is led to a conflict,
Drug effect is influenceed, damages plant, and the type product is used after essentially turning green on the market, rice striking root speed is not worked,
It can not play and accelerate a rice work effect, influence low position tiller, reduce later stage effective tillering.Rice spray plant growth delays
Agent, low dose control prosperous unobvious, and heavy dose does not meet plant and controls prosperous rule in growth, both inhibited the growth of stalk or pressed down
The growth of cauline leaf has been made, so that spike length is reduced, has caused later stage yield reduction.Occur excessively to cause Plant Height of Rice because control is prosperous more
Far below normal plant height, cause the underproduction.It is time-consuming and separately individually repeatedly spraying use causes cost of labor to increase.
Therefore, develop a kind of taken root stage by stage by paddy growth demand and promote the prosperous product of tiller control to increasing production of rice to closing weight
