Abstract
The invention discloses a compound agent for preventing and controlling cotton premature senility, which consists of solid powder and liquid preparation, wherein the solid powder comprises borax, urea and potassium dihydrogen phosphate; the liquid preparation is ethanol solution of brassinolide. The compound agent can improve the physiological activity of cotton plants and increase the nutrition supply in the growth of cotton, thereby solving the problem of premature senility control of cotton to the maximum extent and obviously improving the final yield of cotton.
Description
Technical field
The present invention relates to a kind of built agent, particularly relate to a kind of can the built agent of prevention and control cotton premature senescence, belong to pesticide field.
Background technology
Along with applying of transgenic cotton against pests, the pest-resistant performance of cotton achieves marked improvement, but comes with it, before cotton volt peach ratio increase, growing process in advance, early ageing phenomenon increases the weight of, and become the important factor of restriction Cotton Production development.Slightly there is the time in early ageing, the per hectare unginned cotton underproduction can reach 225kg ~ 300kg, causes China's financial loss to be about 7,500,000,000 ~ 10,000,000,000 yuan, and can more than 15,000,000,000 yuan in the time loss of early ageing severe generation.
Cotton premature senescence, namely " becomes old and weak before one's age ", is due to self or external cause, makes cotton plant body local or overall premature end vital movement and affect the phenomenon of output of cotton and quality responses within the effective breeding season.The factor of the generation of cotton premature senescence is a lot, and comprising the factor of cotton variety itself, weather condition, edaphic condition and cultivation management measure during also comprising cotton growth, is the result of a series of internal and external factor comprehensive action.
With regard to himself reason, may be the hormonoprivia owing to promoting plant strain growth, the shortage of tethelin can affect plant to resistance that is biological and abiotic stress, causes the aging of blade; Also may be the shortage of trophic factor, such as nitrogen nutrition shortage can cause the chlorophyll of integral blade, content of soluble protein significantly declines, mda content raises, the senescence process of speeding-up blade; Potassium ion shortage can cause plant water-retaining capacity to weaken, and have impact on the absorption of potassium ion during olighydria, and the poor potassium state of aggravation cotton plant, accelerates early ageing process.
Increase because transgenic cotton against pests forms bell number, improve the absorbed dose to potassium, cotton is to the soak time Relatively centralized (mainly at flowering and boll-setting period, reaching about 80% of whole growthdevelopmental stage absorbed dose) of potassium simultaneously, the early ageing that factor easily causes later stage potassium deficiency and occurs.The research such as Wright is thought, high-withdrawal area cotton premature senescence problem is more reasonably interpreted as high cotton buds and bolls load and causes with adverse environmental factor (running into accumulated water, cooling or soil salt as the become the bell phase to accumulate) acting in conjunction of interference potassium absorption.
Cotton is boron nutrition critical period before and after buddingging simultaneously, the shortage of boron nutrition element can cause pollen quantity to reduce and fallen flowers bud drop falls peach, aggravation early ageing problem.
Although the early ageing mechanism of this area to cotton defines certain understanding, up to now, the technical scheme of desirable solution early ageing problem is not yet formed.Existing research normally directly goes to solve pathologic early ageing, and be not concerned about long-term nutrition shortage, especially the cotton that not enough, the middle and upper part nutrition supply deficiency of later stage nutrition supply causes continues early ageing, and such as, employing oligochitosan disclosed in CN102613197A/CN201210058543 is used for the purposes of premature senescence resistance and method just exists above-mentioned defect.
Summary of the invention
For the defect of prior art, the invention discloses a kind of built agent of prevention and control cotton premature senescence, according to the main limiting factor that cotton premature senescence is formed, Multiple components is carried out composite, supplement the nutritive ingredient be badly in need of its middle and upper part in the cotton growth later stage in mid-term, to delay early ageing, improve output.
For achieving the above object, the present invention is achieved through the following technical solutions:
The built agent of prevention and control cotton premature senescence, is made up of solid powder and liquid preparation, and wherein solid powder comprises borax, urea and potassium primary phosphate; Liquid preparation is the ethanolic soln of brassinolide.
By above-mentioned composition, brassinolide is utilized to improve the content of plant endogenous growth hormone, regulate synthesis and the metabolism of the protein relevant with growth, the distribution of regulating plant endotrophic material, affect the metabolism of nucleic acid material, thus improve the physiologically active of plant, delay the aging of Vitro Plant cell; By solid powder, early ageing cotton plant middle and upper part nutrition supply can be solved and reduce aggravation early ageing problem, delay early ageing.Composite by above-mentioned two kinds of compositions, solves the early ageing problem of cotton plants to greatest extent, especially uses brassinolide as growth regulator, defines significant synergy, significantly improve the ultimate capacity of cotton with nutritive element.
Wherein, for the different growing states in cotton planting field and the soil fertility of soil, can adjust the composition of solid powder, normally borax, urea and potassium primary phosphate mass ratio are 120 ~ 220:250 ~ 320:200 ~ 320; In the good situation of soil productivity, preferred borax, urea and potassium primary phosphate mass ratio are 180 ~ 220:280 ~ 320:280 ~ 320.
In the present invention, the consumption of brassinolide is relevant to solid powder, in liquid preparation, the quality of brassinolide is the 0.06-0.15% of solid powder total mass generally, and the quality being preferably brassinolide in liquid preparation is 0.1% of solid powder total mass.
Preferably, the concentration of liquid preparation brassinolide used is 0.06g/ml, according to this concentration, in conjunction with the restriction of above-mentioned consumption, and can the volumetric usage of corresponding rearrange liquids preparation.
On the basis of the above, the invention discloses the using method of described built agent, be added to the water by solid powder adds liquid preparation after solid dissolves completely, stirs.
Wherein, every premium on currency solid powder consumption is 5-15g.
Accordingly, can according to solid powder consumption, liquid preparation concentration rearrange liquids preparation add-on.
In order to optimize the absorption of plant to built agent, preferably spray in fine day morning or dusk.The cycle that sprays is about two weeks 1 time, terminates to the term of opening bolls.
The above-mentioned frequency that sprays combines the needs of cotton plants process of growth to tethelin and Nutrient Absorption, is conducive to the equilibrium keeping cotton plants growth.
Above-mentioned pact biweekly, refers to equispaced 12-16 days once.
