Be used for the growth regulator of fruit tree flower-promoting and fruit protecting at present and domestic paclobutrazol arranged, than waiting so long, excellent health azoles (Uniconazole is abroad arranged, S3307) claim uniconazole P again, promptly (E)-1-rubigan-2 (1,2, the 4-triazol-1-yl)-4,4-dimethyl-1 amylene-3-alcohol, excellent health azoles is the efficient plant growth delayer, can be by suppressing fruit tree body inner gibberellin (GA
3) synthetic, the growth of the fruit tree nutrition of inhibition is arranged, prevents effects such as shoot growth is prosperous excessively, stunted tree type, thereby promote the fruit tree reproductive growth, improve stress resistance of plant, promote flower bud differentiation, improve percentage of fertile fruit, finally improve output.The functioning efficiency of excellent health azoles is more contour than paclobutrazol, alar-85, working concentration only is 1/10~1/6 of a paclobutrazol, its accretion rate in soil is fast simultaneously, residual quantity is low, can be as paclobutrazol, more residual for many years in soil than waiting so long, therefore continuous action more meets environment and pollution-free food production requirement.Yet other fruit tree growth such as present excellent health azoles and nucleotide, rare earth element is regulated being used in combination of active substance, yet there are no report both at home and abroad.
The object of the invention is to utilize the advantage of excellent health azoles, makes it and other combinations of substances with plant growth regulating activity, develops a kind of complete function, and the effect that improves fruit yield and quality is better than a planting fruit-trees flower-promoting and fruit protecting element of excellent health azoles.By a large amount of experiments, preferred compositions goes out a planting fruit-trees flower-promoting and fruit protecting element and a complexing agent thereof, has reached purpose of the present invention.
Fruit tree flower-promoting and fruit protecting element of the present invention is characterised in that its composition is the excellent health azoles of 4.5%~55% (weight) and 2.5%~40% (weight) nucleotide and 10%~80% (weight) water dissolvable rare earth compound, and it always consists of 100% (weight).
Said nucleotide domestic production producer is numerous, is mainly derived from the microorganisms such as oil or saccharomycete, generally is made up of adenylate and cytidylic acid and uridylic acid and guanylic acid, and ratio is complexing agent arbitrarily between it, and its composition is different because of producer, can use.
Said water dissolvable rare earth compound is that all water solubles are in the water rare earth compound that does not endanger human and livestock health free from environmental pollution.Domestic production producer is numerous, generally is the compound of rare earth element mineral salt such as lanthanum, cerium, yttrium, can be nitrate, chloride etc., and its composition is different because of producer, can use.
The plain best composition of fruit tree flower-promoting and fruit protecting of the present invention is the excellent health azoles of 18% (weight) and 12% (weight) nucleotide and 70% (weight) soluble ree compound.
Fruit tree flower-promoting and fruit protecting element of the present invention can be made wetting powder or granula by usual method, dilutes the back in the fruit tree foliage-spray by quality with 1000 times of water during use.
Fruit tree flower-promoting and fruit protecting element of the present invention can with all one or more water dissolvable fertilizer as the fruit tree nutrition agent, compound with any ratio, become the plain complexing agent of fruit tree flower-promoting and fruit protecting of the present invention.
Described fertilizer is nutritional agents such as the urea that is applied to fruit tree usually, superphosphate, carbonic hydroammonium, potassium sulphate, potassium chloride, magnesium sulfate, ammonium molybdate, borax etc.
According to magnesium, the zinc element of lacking in the Southern Red Soil, can select for use magnesium sulfate and zinc sulphate as the fruit tree nutrition agent more.
The best composition of the plain complexing agent of fruit tree flower-promoting and fruit protecting of the present invention is plain and 21.5% (weight) magnesium sulfate and 68% (weight) zinc sulphate composition of 10.5% (weight) fruit tree flower-promoting and fruit protecting of the present invention, and it always consists of 100% (weight).Described fruit tree flower-promoting and fruit protecting element is preferably described best the composition.
The plain complexing agent of fruit tree flower-promoting and fruit protecting of the present invention can be made wetting powder or granula by usual method, after diluting with 1000 times water by quality during use, in the fruit tree foliage-spray.
Fruit tree flower-promoting and fruit protecting of the present invention is plain owing to excellent health azoles and nucleotide and rare earth element combination had both been kept the advantage of excellent health azoles, the nutrition of nucleotide performance and the effect that hormone haves both at the same time are arranged again, can obviously improve plant leaf blade photosynthesis level, minimizing children flower, young fruit come off, and improve fruit quality; Rare earth element in the composition can improve fruit tree resistance, and under adverse circumstance situations such as high temperature, arid, the fruit tree defensive ability/resistance ability strengthens, so it is a kind of growth regulator for fruit tree of complete function, it can suppress fruit tree nutrition and generate control shoot, raising leaf photosynthesis level; Promote flower bud differentiation, improve flower matter and female flower ratio; Alleviate physiological fallen fruit, improve percentage of fertile fruit, improve output.Moreover, and because portfolio ratio is through preferred between plain each component of flower-promoting and fruit protecting of the present invention, and amount of application is accurately control easily, so that produce synergy between component, and make their effectiveness bring into play better, activity is lower.
The plain complexing agent of fruit tree flower-promoting and fruit protecting of the present invention is except the advantage with above-mentioned fruit tree flower-promoting and fruit protecting element, since growth regulator and nutrition built in component and between it ratio aspect passed through preferred compositions, use conveniently, and can accurately control amount of application, so that produce synergy between component, and the bigger effectiveness of performance, working concentration reduces.Contain the essential magnesium of growth and development of plants in the complexing agent of the present invention, zinc element can excite metabolic enzyme activity, promotes the tree bulk-growth.
Fruit tree flower-promoting and fruit protecting element of the present invention and complexing agent thereof are applied on the fruit trees such as shatian pomelo, longan, the result shows: the fruit tree chlorophyll content increases by 19.2%~24.1%, photosynthetic rate increases by 20.7%~39.2%, the shoot growth amount reduces 31.5%~77.1%, the superoxide dismutase of fruit tree leaf, catalase and ascorbic acid peroxidase activity rise 72.5%~132.7% respectively, 58.2%~81.0% and 25.0%~66.4%, show that the degeneration-resistant border of fruit tree ability improves; The one-tenth spray tip rate of longan raises 15.1%~148.3%, and male and female flowering is than rising 35.7%~64.2%.Flower spike length and flower branch of the ear of grain spacing reduce 44.3%~70.5% and 10.5%~41.9%; Shatian pomelo strain output increases by 17.4%~42.2%, and the sugar content of fruit increases by 10.5%~19.2%; Longan strain output increases by 32.1%~103.8%, and the sugar content of fruit increases by 14.8%~26.6%.
Fruit tree flower-promoting and fruit protecting element of the present invention and complexing agent thereof are applicable to each fruit trees, especially tropical and subtropical zone fruit trees such as oranges and tangerines, shatian pomelo, longan, lichee, mango, the effect that itself and excellent health azoles, nucleotide, solubility sulfuric acid rare earth complexing agent (abbreviation compound rare-earth) use separately respectively relatively sees embodiment and table 1 for details.
