Abstract

The invention provides a rice plant growth regulator in a tillering stage. The rice plant growth is prepared from the following components in proportion: 0.02-0.05ppm of BR (brassinolide), 12-25ppm of GA3 (gibberellin 3), 12-25ppm of NAA (naphthylacetic acid), 2-8ppm of ABA (abscisic acid), 1-2ppm of paclobutrazol, 200-250ppm of tricyclazole, 150-200ppm of buprofezin wettable powder, 1500ppm of ethanol and 800ppm of diethyl ether, wherein a carrier is distilled water.

Description

A kind of tillering stage the rice plants growth regulator

Technical field

The invention belongs to the plant growth regulator field, particularly relate to rice plants growth regulator in a kind of tillering stage.

Background technology

Paddy rice in China's most areas always all as staple food, the raising of its quality and yield is the direction that people study and make great efforts always, for a long time, we improve output by insect protected and the diseases prevention that the agricultural chemicals with the high poison of high concentration carries out paddy rice, in recent years engineered research can improve the yield and quality by gene engineering directed change paddy gene us, but, the environment of having used severe contamination in a large number of agricultural chemicals, even the injury that some soil reclamations can't be reversed, and advanced gene alteration paddy rice its whether have also final conclusion not of potential hazard, many people are also worried edible;

Rice plant of tillering stage (tillering stage) is to tiller since the birth of the 4th leaf, stops until jointing is tillered, and is divided into three periods: period of seedling establishment, effective tiller and ineffective tillering; Be the important period that determines that spike number also lays the foundation for Development of ear and grain this period, and main management objectives are to promote that root of hair is good, and it is fast to turn green, tiller early, form enough strong tillers, prevent stiff seedling, rice plant of tillering stage,, Major Diseases had simultaneously: rice blast, the rice sheath blight, the rice Huang leaf disease etc. of stunting; Insect pest has: borer, rice fulgorid etc.;

Since the forties in 20th century, plant growth regulator (plant growth regulators) is widely used in regulating and control crop growth, and plant growth regulator is the material that a class and plant hormone have similar physiology and biological effect; For target plant, plant growth regulator is the non-nutritive chemical substance of external source, usually can conduct to site of action in plant corpus, just can promote or suppress some link of its life process with very low concentration; Can be used for nucleic acid, protein and Enzyme Production in the regulating plant body such as plant growth regulator, can to the different phase in the plant growth and development process as germinate, take root, cell elongation, Organ Differentiation, flower bud differentiation, bloom, result, fallen leaves etc. play the regulation and control effect, make it to meeting human needs development.

Summary of the invention

The purpose of this invention is to provide a kind of rice plants growth regulator in tillering stage that output shortens vegetative period that improves, this growth regulator can promote root system development, and it is fast to turn green, and tillers early, forms enough strong tillers, prevents stiff seedling, also can improve resistance and prevent damage by disease and insect;

For addressing the above problem, the invention provides rice plants growth regulator in a kind of tillering stage, each component in this rice plants growth regulator is made by following proportioning, and carrier is distilled water:

The BR(study on brassinolide) 0.02～0.05ppm, GA3(gibberellin 3) 12 ~ 25ppm, NAA(methyl α-naphthyl acetate) 12 ~ 25ppm, ABA(abscisic acid) 2 ~ 8ppm, paclobutrazol 1 ~ 2ppm, tricyclazole 200～250ppm, buprofezin wetting powder 150～200ppm, ethanol 1500ppm, ether 800ppm.

The invention provides the method for the above-mentioned reproductive stage rice plants growth regulator of preparation:

Take by weighing each raw material for standby by proportion of composing; BR, GA3, NAA, paclobutrazol are dissolved in the ethanol, and ABA, tricyclazole, buprofezin wetting powder dissolve in the ether; More than both mix, stir the adding distil water constant volume.

Tillering stage, the application process of rice plants growth regulator was:

Adopt the method for foliage-spray; After the fertilising, respectively spray once in rear the 4th day of rice seedling transplanting and primary tiller phase, each every mu sprays this plant modifying agent of 50kg, and the fine day that is chosen in 25～30 ℃ sprays.

This in tillering stage each component of rice plants growth regulator best optimum ratio:

The BR(study on brassinolide) 0.032ppm, GA3(gibberellin 3) 18ppm, NAA(methyl α-naphthyl acetate) 18ppm, ABA(abscisic acid) 4.5ppm, paclobutrazol 1.25ppm, tricyclazole 235ppm, buprofezin wetting powder 175ppm, ethanol 1500ppm, ether 800ppm.

Useful effect: this, each factor ratio of rice plants growth regulator was reasonable in tillering stage, had various mutual works, and their effect is relative opposition, again organic connections, can promote root of hair good, it is fast to turn green, and tillers early, increase and tiller, form enough strong tillers, increase photosynthesis, prevent stiff seedling, the many tillers of favourable cultivation are strengthened seedling, also can improve resistance, add the function that insecticide can increase prevention and elimination of disease and pests; The present invention is easy to use, absorbs rapidly, instant effect and lasting;

BR has and promotes cell elongation and division to improve chlorophyll content, promotes photosynthesis and strengthens anti-adversity ability, makes the real grain of paddy rice heavy, thousand kernel weight has obvious increase;

GA ₃Have and promote cell division, cell elongation, bolting to bloom, improve plant height, the spike of rice regularity of tillering tassel, increase the tongue phase and tiller into fringe, improve solid;

NAA is the broad spectrum type plant growth regulator, can promote cell division and expansion, induces to form the adventive root increase and bear fruit, but stimulating growth, increases and tiller; Through the tender epidermis of blade, branch, seed enters in the plant, and to complete stool, NAA is cheap with the nutritional flow transporting;

ABA is the key factor of balance plant endogenous hormones and relevant growth activity metabolism; Have the ability that promotes plant Balance Absorption water, fertilizer and coordinate internal metabolism, but the root of Effective Regulation plant/be preced with and nourishing and growing and reproductive growth has important function to quality, the output of raising crops; Also effective degeneration-resistant immune system in the activated plant body has the training source and consolidates, and strengthens the ability of comprehensive plant resistance (drought resisting, heat resistanceheat resistant, cold-resistant, Resistant, anti-saline and alkaline etc.);

Paclobutrazol has retarding of growing speed, the growth of control cauline leaf, prevents excessive growth, promotes root growth, and increase is tillered, and strengthens photosynthesis, is conducive to cultivate the strong seedling of many tillers, can strengthen seedling age elasticity;

Tricyclazole, buprofezin can be prevented and treated leaf blast and snout moth's larva, and the two is large diseases of rices plant of tillering stage two.
