Abstract
The invention relates to a method for promoting the growth of a plant propagation material, wherein an effective amount of zinc thiazole is used for treating the propagation material, and the growth promotion of the plant propagation material is realized by means of increasing the germination rate and improving the quality of seedlings. Due to adoption of the method for treating the plant propagation material by using the zinc thiazole, the germination rate is increased by more than 5 percent, the germination potential is increased by 10-20 percent, the activity of a root system is increased by more than 8 percent, the dry weight of roots is increased by more than 12 percent, the thickness of stalks is increased by more than 10 percent, and the length and quantity of the root system are both obviously increased.
Description
Technical field
The present invention relates to a kind of method that promotes that plant propagation material is grown, particularly by use the zinc thiazole of effective dose to plant propagation material.
Technical background
On the earth, population is more and more, needs on the one hand more continuable resource to meet its demand, and it is exactly a kind of important resource that plant especially provides the crop of food.And the plant of occurring in nature is more and more subject to the environment challenge causing from human factor on the other hand, such as causing soil compaction, salinization of soil because of a large amount of chemical fertilizer that uses; Unreasonable applying pesticides causes that Pest rampancy, disease are complicated, weeds malignization; The anomalous weathers such as arid, damage or crop failure caused by waterlogging threaten and cause plant growth abnormal; Irrational pattern of farming, long-term continuous cropping is planted a kind of crop, huge to the destructive power of soil mineral and biotic population system.If the plants are germinating, the stage is subject to coercing of poor environment, and growth is suppressed, and weakens in occurring in nature competitiveness, blooms, result or ripe quality by having a strong impact on.In addition, some propagating materialss are departing from after parent, under new environment, sprout and growth of seedling, and also imperfection of root system and blade function, need to better take good care of, and therefore, neat germination, healthy and strong seedling are even more important to healthy plant growth.
Zinc thiazole is a kind of organic zinc bactericide.CN1152869C discloses zinc thiazole (Zinc thiazole) for preventing and treating the purposes of bacteriosis.Using bactericidal agent for preventing and treating disease is the important measure of protective plant yield and quality; and propagating materials is sprouted neat and seedling stalwartness; make plant just possess the ability of the extraneous poor environment of good opposing in the immature stage; further reduce the consumption of propagating materials; reduce the use of fertilizer and agricultural chemicals, alleviate environmental pressure.In research process, we delightedly find that zinc thiazole not only prevents and treats bacteriosis, and growth and development of plants is also shown to very strong effect, and this is that similar compound is not available.
Summary of the invention
The present invention is intended to solve the problem that promotes that plant propagation material is grown.For this reason, the invention provides a kind of method that promotes that plant propagation material is grown, it is characterized in that, by using zinc thiazole to plant propagation material.Described promotion plant propagation material is grown by raising germination rate, seedling quality and is obtained.
Germination rate of the present invention refers to the propagating materials quantitative proportion of actual rudiment in new tissue or soil within a certain period of time, can be with germinateing, the quantity of emerging weigh.Described germination vigor refers to speed and the regularity that propagating materials germinateed in the development stage.Germination rate is weighed germination quantity, and germination vigor is weighed germination quality.Described seedling quality refers to the variation contrast of the seedling physiology index after sprouting, as root system situation and sturdy degree, Physiology and biochemistry etc.
The usage amount of chemical substance is huge to ozone deplation.Use too much, not only injure plant, and affect surrounding enviroment and food security, usage amount is very few, fall flat, and waste resource.
Therefore, in one embodiment, plant propagation material is processed with the zinc thiazole that effective dose is 0.02-10g/L.In a preferred embodiment, the effective dose of zinc thiazole is 0.04-4g/L.
In the present invention, indication plant propagation material comprises plant complete stool or the part of cultivation, wild Gong breeding, as nursery stock (containing test-tube plantlet), fruit, seed, stock, scion, cutting, sprout, piece root, stem tuber, bulb, bulb, pollen, plant culture materials (containing genetically modified plants) etc.
In a preferred embodiment, propagating materials is selected from seed, piece root, stem tuber.
In a particularly preferred embodiment, propagating materials is selected from seed.
It is well-known that biology or abiotic stress cause via plant immunity to decline, be usually expressed as blade imperfect, a little less than receiving photosynthesis ability, plant growth is suppressed, and root system is undeveloped, and mineral absorption and transhipment are poor, plant nutrition is unbalanced, plant is short and small, and poor to the competitiveness of light, water, fertilizer, the systemic immunity ability of plant declines.
And root system is the vitals that plant absorbs and transport nutriment, mineral matter and water, strong and weak growth and the existence that directly affects plant of root system.According to the present invention, zinc thiazole can strengthen root system of plant vigor, active raising more than 8%, and root length, rugosity and quantity all obviously increase, and plant growing way is vigorous.
In one embodiment, improve plant seedlings extent of the root system, quantity and root dry weight by the zinc thiazole treatment of plant propagation material of effective dose.
The method according to this invention, uses zinc thiazole treatment of plant propagation material, not only pre-disease prevention, and strengthen plant seedlings autoimmunity, greatly strengthen the ability of plant competition light, water, fertilizer.Make plant just possess the ability of the extraneous poor environment of good opposing in the immature stage, the consumption of minimizing propagating materials, reduces the use of fertilizer and agricultural chemicals, alleviates environmental pressure, for high yield good harvest is laid a good foundation.The method of described zinc thiazole treatment of plant propagation material, improves germination rate more than 5%, and germination vigor improves 10-20%, and root system activity improves more than 8%, and root dry weight increases more than 12%, and stem stalk rugosity improves more than 10%, and root length and quantity are all significantly improved.
For ease of using, those skilled in the art can be prepared into zinc thiazole multiple formulation, as water dispersible granules, suspending agent, pulvis, suspension emulsion, seed suspending agent, microcapsule suspending agent, wafer, seed coating medicine, seed dressing etc., use the zinc thiazole of these formulations can more convenient bandwagon effect, only prepare 5% and 10% zinc thiazole suspension seed-coating agent below take suspension seed-coating agent as example.
For ease of describing, in following examples, use zinc thiazole concentration all to refer to active ingredient concentration, non-formulation concentrations.
