Abstract
The yield-increasing composition for crops contains, by wt.%, nutrients (73.5-90.8), sodium hydrogen sulfite (1.48-3.0), broad-spectrum plant growth regulator (4.5-1.5), specific active substances (2.2-6.0) and surfactant (0.7-2.5), and serves to improve growing condition, raise chlorophyll content and increase resistance and yield with low cost and no pollution.
Description
The present invention relates to a kind of Yield increasing agent composition that is used for the crop foliage-spray, belong to plant nutrition and developmental regulation field.
In crop genetics, enriching foliage fertilizer is important measures that improve output.In recent years, the multiple fertilizer that is used for the crop foliage-spray has appearred.These foliage fertilizers as photosynthetic one little fertile leaf fertilizer (CN1020446C), foliar fertilizer specially used for peanut (CN1085884A), contain various macronutrient nitrogen, phosphorus, potassium, calcium, iron, sulphur etc. and the trace element of plant growth needs.Some foliage spraying agents are also arranged, contain common broad spectrum activity plant growth regulating substance, as gibberellin (GA), methyl (NAA), Daminozide (B
9), help strong plain (Pix), brassin lactones etc., thereby can improve nutrition status of the plant, regulate crop growth, improve photosynthetic efficiency, reached the purpose of volume increase.Yet these foliage fertilizers show that to the land for growing field crops large tracts of land operating position of vegetables, fruit tree and cereal crops though it can regulate and control the growth of crop plant, the quality of seed fails to significantly improve.And the crop specificity is relatively poor, causes effect of increasing production not really desirable.In addition, these foliage fertilizers need repeatedly spray in crop growth period usually, and are time-consuming.
The present invention aims to provide a kind of multi-functional Yield increasing agent composition for crops, and it can not only improve growth and the development condition of plant, improves photosynthetic efficiency, strengthens resistance, and can improve the quality of seed, improves output.Possesses advantage with low cost, easy to use, free from environmental pollution, as to be easy to large scale application in agricultural production simultaneously.
Yield increasing agent composition for crops of the present invention not only contains the necessary macroelement of crop growth and trace element and broad spectrum activity plant growth regulating substance, and contains crop activity specific material.Specifically, Yield increasing agent composition for crops of the present invention is formed by the reasonable assembly of following five class materials, they are respectively: the category-A material, be plant nutrient ingredient, category-B material, be that photosynthetic usefulness promotes composition, C class material, be broad spectrum activity plant growth regulating substance, D class material, i.e. crop activity specific material and E class material, i.e. surfactant.
Wherein, the category-A material contains necessary macroelement of crop growth and trace element, comprise nitrogen, phosphorus, potassium, calcium, sulphur, iron, zinc, manganese, boron, molybdenum, chlorine, sodium element composition, other composition exists with the form of sulphate, phosphate, boric acid and molybdate respectively except that urea, and contained ratio is different because of agrotype and region characteristic.Such material can improve the crop plant nutrition condition, promotes harmonic growth and growth, quickens the transhipment and the conversion of photosynthate.
The category-B material is a sodium hydrogensulfite, and this compound can promote the photosynthetic efficiency of blade under low light intensity condition under suitable concentration, increase organic matter accumulation.
C class material, promptly the broad spectrum activity plant growth regulating substance comprises Daminozide, paclobutrazol, casing coupling peace, 2.4-dichlorphenoxyacetic acid, their function is to regulate and control growth and the growth of crop.Because the physiological function of different growth regulatory substances has notable difference, and with a kind of growth regulatory substance for different crops, its effect is also variant, and, crop difference in residing vegetative period, kind of its needed adjusting material and concentration also are different.Thereby be necessary to adopt the short ＂ ＂ control of ＂ " combination, because of thing because of the time principle, can obtain desirable effect of increasing production.Select for use Daminozide, paclobutrazol, casing coupling peace to be all growth inhibitor in the Yield increasing agent composition for crops of the present invention, can both suppress plant height, improve strain shape, improve chlorophyll content in leaf blades, strengthen plant resistance.Daminozide and casing coupling peace also can promote the root system vigor.For Different Crop, the action effect of three kinds of inhibitor has evident difference.Can significantly reduce the plant height of paddy rice, peanut as paclobutrazol, and casing coupling is positioned on effect optimum in the control of cotton strain shape.2.4-dichlorphenoxyacetic acid is a plant growth promoter, the 2.4-dichlorphenoxyacetic acid of low concentration can promote cell division and plant strain growth, the 2.4-dichlorphenoxyacetic acid of high concentration can kill dicotyledon, and Different Crop is to the susceptibility difference of 2.4-dichlorphenoxyacetic acid.In a word, in order to obtain best effect of increasing production, need select for use different plant growth regulating substances to carry out reasonable combination according to crop species and region characteristic.
D class material, promptly crop activity specific material comprises resorcinol, (Jiao's property) gallic acid, P-hydroxybenzoic acid, sodium salicylate and carboxymethyl cellulose.Physiologic Studies shows, resorcinol [C

-3] in plant corpus, have the function of signaling molecule, can strengthen cell respiration intensity, be the precursor substance of synthetic lignin, the involved in plant defense response.Sodium salicylate (HOC
6H
4COONa) and carboxymethyl cellulose be the elicitor of plant defense, can strengthen plant drought, waterlogging-resistant and resistance against diseases, can strengthen the resistance of plant.P-hydroxybenzoic acid (HOC
6H
4COOH) and sodium salicylate the growth of certain plants is had the obvious suppression effect, can cause the cytoplasma membrane depolarising, increase the permeability of ion, and can stimulate the active of indoleacetic acid oxidase or constraint cell inner gibberellin, enhance metabolism and photosynthesis, improve the resistance of crop., spray this class active substance and can increase production in the phase at the suitable growth of some crop, spray resorcinol or (Jiao's property) gallic acid, can promote the peanut pin down of blooming, improve pod output as full-bloom stage at peanut.
E class material, it is surfactant, be to form by neopelex and lauryl sodium sulfate assembly, it makes the Yield increasing agent composition aqueous solution can stick on the leaf surface of crop preferably, has the function that alleviates or prevent and treat some virus and fungus-caused disease, and it is nontoxic to people and animals, and is free from environmental pollution.
