Description
One, technical field
The present invention relates to a plant growth regulating control technology, be specially a kind of growth regulator of pinching and being used with cotton.
Two, background technology
In cotton planting,, limit it and nourish and grow in order to control plant height, promote reproductive growth, under limited photo-thermal resources supplIes and liquid manure supply level, obtain more relatively cotton boll, strive for obtaining high yield, (flowering and boll-setting period) removes cotton stem top (pinching) normally at later stages.The cotton deburring of in good time pinching is rationally to regulate and control cotton nutrition growth and reproductive growth, moulds reasonable plant type, improves the ventilation and penetrating light condition, alleviates disease, promotes cotton plant to tie bell, the effective high-yield culturing measure of the big bell of knot more, is widely used at present.
But after cotton was pinched, square and shedding were more serious, became the minimizing of bell number, bell heavily to reduce, and severe patient comes off in a large number at the blow-of-cottons front vane, produces the early ageing imagination, and output of cotton and quality are affected.Research report proof is arranged, can cause the growth of lateral bud behind the plant removal apical dominance, use exogenous auxin can replace the effect on plant top to suppress the growth (ThimannKV of lateral bud, et al.Pro Nid Acad Sci (Wash), 1933,19:714), growth hormone decision mineral element that the plant top produces and assimilation material transporting direction and distribution (DaviesCR.et al.JExp Bot thereof in vivo, 1987,38:203-210).Removed the apical dominance of plant owing to pinch, changed the organic centre of cotton plant, great changes will take place to make source, the original storehouse of cotton plant relation, has influence on the distribution of interior assimilation products of body and mineral nutrient, causes cotton premature senescence, and cotton buds and bolls are come off in a large number.Simultaneously people are slowing down and are eliminating and carried out research work aspect the negative effect of the generation of pinching, a lot of technical measures have been proposed, for example: 1, flowering and boll-setting period imposes nitrogenous fertilizer: can delay leaf senile, increase bell heavily after imposing nitrogenous fertilizer, but the effect of guarantor's bell is very not remarkable; 2, spray guarantor's bell growth regulator of steroids: although there is the research report can promote nutriment to the running of flower bell to smearing or spray exogenous hormones such as growth hormone, the basic element of cell division on flower, the bell, increase and protect the bell ability, be difficult to operation but aborning growth regulator is directly sprayed application to Hua Lingshang.Normally the steroids growth regulator is directly sprayed on blade, this has just caused nourished and grew prosperously, and leaf-area coefficient increases, and lower blade is sheltered from heat or light, and causes reproductive growth to slacken relatively; 3, Zhang Juansheng proposes can to a certain degree reduce cotton buds and bolls exfoliation with " encircling the embedding method ", but effect is limited, and should not be under the dense planting pattern implementation and operation; 4, application number is 01110350 the disclosed a kind of plant growth regulator that improves potassium content in tobacco leaf of Chinese patent specification, uses when pinching in conjunction with tobacco, but only is suitable for and tobacco.
In sum, also do not have at present the desirable method that prevents cotton buds and bolls exfoliation and eliminate early ageing, particularly pinching with cotton is used, and can eliminate negative effect, compensation plant corpus internal hormone level and keep the method for regulating source, original storehouse relation.
Three, summary of the invention
The objective of the invention is effectively to slow down the effective ways of cotton buds and bolls exfoliation and prevention early ageing for what provide a kind of and cotton to pinch to be used.
The technical scheme that the present invention proposes is a kind of growth regulator of pinching and being used with cotton, described growth regulator is made up of plant hormone, lanolin, OP-10, weight ratio between each component is 0.1-1.5: 2000: 100-200, and described plant hormone be methyl and gibberellin by 1: the mixture of 0.5-1 proportioning.
The using method of this growth regulator is: coat deployed growth regulator at the stem top surface of a wound immediately after cotton is pinched, applying amount is 0.5-1.0 gram/strain, then with tin platinum or reason position, the black paper bag dwelling of waterproof, until harvest home.
Because methyl is a kind of auximone, have the promotion plant growing, the effect that regulation and control plant nutrient substance and photosynthate move in plant corpus, it is mainly by the top generation of plant.After cotton is pinched, remove the growing point of plant, controlled plant height and nourished and grown, promoted reproductive growth and knot bell blow-of-cottons, helped the raising of crop yield.But after pinching, the synthetic growth hormone quantity of plant significantly reduces, can not keep original hormonal readiness, conveying to endotrophic material and photosynthetic product exerts an influence, make nutrient and photosynthetic product transportation and transfer diminishes to reproductive organs, thereby increase the weight of cotton buds and bolls exfoliation, and cause cotton growth the early ageing phenomenon to occur.After the invention process, pinch the back by the certain exogenous growth hormone of top wound surface smearing supply, can keep original hormonal readiness in the plant corpus in cotton, promote the supply and the conveying of nutrition, adjusting is nourished and grown and the balance of reproductive growth, can reduce fruit abscission rate, slows down the generation of early ageing.After gibberellin is absorbed by crop in addition, not only can induce the content that improves growth hormone in the plant corpus, and the division of pair cell also there is facilitation, can induced flowering, improve fruit-setting rate, promote fruit growth, the delayed fruit aging can significantly reduce fruit abscission rate.Lanolin and OP-10 (condensation product of alkyl phenol and oxirane) play the emulsification slow releasing function, make the hormone uniformly emulsify and keep slowly-releasing, effectively to be absorbed by crop.
After adopting method as above, fruit abscission rate significantly reduced after cotton was pinched, and became the bell rate to improve more than 20%, and output improves 13-40%.
