Description
Technical field
The present invention relates to a kind of plant growth regulator composition and uses thereof, especially a kind of plant growth regulator composition that contains maleic hydrazide is used to regulate the application and the composition composition thereof of cultivated plant growth.
Background technology
In recent years, China's plant growth regulator is used area and is constantly enlarged, the output of plant growth regulator and consumption are also improving year by year, though the plant growth regulator of single variety is fine to the regulating effect in some crop field, but because the application of single plant growth regulator is narrower, crop-selective is stronger, and effect is undesirable, also some crop is existed potential poisoning danger simultaneously.Therefore, use exploitation with complex preparation with between the plant growth regulator, become one of main developing direction of plant growth regulator industry, use with and the composite decapacitation of plant growth regulator enlarge adjustable range, improve outside drug effect and the selectivity, can also reduce the dosage of plant growth regulator, reduce drug cost relatively, and the longevity of residure of shortening medicament, avoid poisoning, make crop safety, thereby the composite and application of plant growth regulator has become the main developing direction of plant growth regulator industry developmental research.
Maleic hydrazide is a kind of selectivity and temporary plant growth inhibitor, and medicament can enter plant by cuticula from the blade face.It has conduction in plant corpus. and can suppress cell division and do not enlarge cell, reduce photosynthesis of plants, osmotic pressure and evaporation; Suppress the growth of bud and the elongation of stem consumingly; Improve cold tolerance; Prevent that potato, garlic etc. from germinateing in storage period; Induce fruit parthenocarpies such as citrus, form stenospermocarpy.Mainly use on a small quantity, and the face that uses is also narrower in pressing down on the tip of garlic, onion, tobacco and some fruit tree.And paclobutrazol, uniconazole P, chlormequat, the first piperazine, triapenthenol, daminozide, the independent use of conditioning agents such as ethrel, still there is drug effect worse and worse, pharmaceutical quantities is used bigger and bigger, various problems such as drug cost is high, China more and more payes attention to cultivation and the management of ornamental plant in addition, isolate and play boundary, the hedgerow of zoning scope and beautifying and decorating effect is one of indispensable part in the greenery patches, gardens, along with planting of a large amount of gardens hedge plant and lawn, especially the fast and hedge plant that needs to keep aesthetic appearance of growing way, its artificial pruning workload is very big.Simultaneously fruit tree (particularly tropical fruit tree), vegetables, economic crops, cereal crops, oil crop, control its apical dominance, to nourish and grow is converted into reproductive growth, promotes to blossom and bear fruit, and all needs plant growth regulator to replace artificial pruning and adjusting growth.So study the compound botanical growth regulator new varieties of safety, efficient, low consumption, low cost, easy use, labor savings and enlarge its purposes and application technical research, be an urgent demand that current plant cultivation is produced.And existing plant growth regulator, there is no the plant growth regulator composition of maleic hydrazide, with and cultivated plant: the example of using as hedge plant, lawn, ornamental plant and fruit tree, vegetables, economic crops, oil crop, cereal crops, the growth of herbage adjusted.
Summary of the invention
The object of the invention provides the application that a kind of plant growth regulator composition that contains maleic hydrazide is regulated the cultivated plant growth, it is characterized in that, use 1-8000mg/kg, be preferably the plant growth regulator composition that contains maleic hydrazide of 50-5000mg/kg, water or soil are diluted to desired concn, by pouring, broad irrigation is with the water dispenser, spray, spraying, spray, smear, injection, transfusion, seed dressing, spread fertilizer over the fields or processing cultivated plant such as distribution: for example hedge plant (comprises glossy privet, common box, little leaf boxwood, spindle tree, Buxus bodinieri, Chinese juniper, pittosporum tobira, sweet viburnum, fernleaf hedge bamboo, serissa serissoides, fujian tea, thousand pollard Chinese ephedras, kamuning, juniper, arbor-vitae, podocarpus, little cured, Chinese ilex), the lawn, ornamental plant, fruit tree (comprises grape, apple, pears, peach, Lee, apricot, cherry, claim the monkey peach, jujube, oranges and tangerines, lichee, longan, banana, mango), vegetables (comprise custard squash, cucumber, wax gourd, pumpkin, watermelon, muskmelon, capsicum, eggplant, tomato, pinto, day lily, potato, carrot, leek, shallot, onion), economic crops (comprise beans, tobacco, cotton, tealeaves, rubber, coffee, flax), oil crop (comprise rape, peanut, sesame), cereal crops (comprise wheat, corn, paddy rice) and herbage crops such as (comprising clover).
Another object of the present invention provides applied widely, cost is low, effective, the plant growth regulator composition that contains maleic hydrazide with synergistic effect, except the inertia processing aids of routine, contain as following active components and make up: A) maleic hydrazide and B) at least aly be selected from following plant growth regulator: paclobutrazol, uniconazole P, chlormequat, the first piperazine, triapenthenol, daminozide, ethrel, chlorpropham, 6-benzyl aminopurine, CPPU, Thidiazuron, salicylic acid, indolebutyric acid, indolebutyric acid, Tianjin quinoline difficult to understand, kinetin, gibberellin, methyl, triacontanol, fulvic acid, 2,4-drips, drop-proof agent (p-chlorophenoxyacetic acid sodium), diethyl aminoethyl hexanoate, nitro humic acid and jasmonic, wherein component A) and weight ratio B) be 1: 300 to 500: 1.It can be mixed with any one formulation that allows on the agricultural chemicals with known auxiliary agent and excipient.For example liquid preparation and solid pharmaceutical preparations such as soluble liquid, aqua, aqueous suspension, microemulsion, aqueous emulsion, dispersible agent, finish, ultra low volume liquids, ultra low volume microcapsule suspending agent, missible oil, suspending agent, paste, dense glue (cream) agent, liniment, plastics, wetting powder, soluble powder, water-dispersible grain (sheet) agent, effervescent agent.
