Description
Technical field
The present invention relates to pesticide fields, more particularly, to a kind of Compositional type seed coat agent and its preparation method and application.
Background technique
Mainly improve the cold tolerance of cotton in seedling stage in production from the following aspects at present: first is that traditional agriculture method makes
With film and fertilizer is applied, planting early enough is realized by the method for heating and increasing fertility of land, is early emerged, resistance low temperature, but this side
Method operating difficulties, waste of resource, pollution environment, influence the sustainable development of agricultural；Second is that the Cold exposed of plant, in low temperature environment
Lower induction plant generates cold-resistant defense mechanism, and feature is the gene for relying on crop itself, therefore is related to bio-screening technologies, mesh
Preceding bio-screening technologies are cross-breeding, screen cold-resistant product by genetic engineering culture cold-resistant kind or by tissue cultures
System, the method have that complicated for operation, limitation is big；Third is that using external source biochemical substances, to seed or seedling
Reason enhancing crop cold resistance, this method is easy to operate, at low cost, is lacked using artificial, meets the agriculture of Rural Areas at Present labor shortage
Industry production status.
Using in external source biochemical substances approach using it is more be seed coat agent.Will dry or moisture state seed, with containing
There is the composition pesticide of binder to be wrapped, makes to form the protective layer that there is certain function and coat intensity, this mistake outside seed
Journey is known as seed pelleting, wraps the combination substance outside seed and is referred to as seed coat agent.
Seed pelleting has become the important technology for solving the problems, such as that cotton germination phase and seedling stage damage to plants caused by sudden drop in temperature in cotton in Xinjiang production and arranges
Apply, many scholars have conducted extensive research sead coating agent for cotton seeds seedling protecting effect, but primarily focus on controlling disease, can only prevent and treat because
Disease pest caused by low temperature etc. cannot improve the low temperature tolerance ability of cotton seed itself.
Summary of the invention
In view of the problems of the existing technology, the present invention provides a kind of Compositional type seed coat agent and its preparation method and application,
The Compositional type seed coat agent is while the insect pest and soil-borne disease for effectively preventing cotton germination phase and seedling stage, moreover it is possible to improve cotton seed
Germination percentage and emergence rate, enhancing cotton germination period and seedling stage low temperature tolerance ability.
The present invention provides a kind of Compositional type seed coat agents, including medicament A and medicament B, the medicament A include following parts by weight
Active constituent: 15-25 parts of Diacloden, 2-5 parts of fludioxonil and 5-10 parts of Metalaxyl-M, the medicament B includes following parts by weight
Active constituent: 10-20 parts of salicylic acid.
In above-mentioned technical proposal, salicylic acid (SA) i.e. septichen, as one of potential endogenous plant hormone,
It is a kind of simple phenolic compound.In recent years, discovery SA has the plant abiotic resistance effect that improves successively, such as improve
Salt-resistance, drought resistance, winter resistance and the heat resistance of plant；When plant is by ultraviolet irradiation, ozone stress, endogenous SA is in product
It is tired, and have pathogenesis-related proteins generation.Production at present it is upper for salicylic acid improve cotton seed anti-seismic design be by soaking seed or
Mode is sprayed, but both modes can not be applied in cotton in Xinjiang production, because cotton in Xinjiang production model is, with sowing
Machine first sows seed, when same day temperature degree is suitable, carries out trickle irrigation, belongs to emergence of dripping, and seed soaking discomfort shares machine sowing, takes
Expenses of labour power is not suitable for the production model in Xinjiang；The mode sprayed, acts only on aerial part, is not suitable for Their Seed Germinating Period.
So the present invention proposes new approaches, bactericide compounded with insecticide with salicylic acid, each component plays synergistic effect, improves cotton seed and exists
Germination percentage and emergence rate under cryogenic conditions promote plant growth and increase cotton seed resistance to low temperature, while enhancing cotton and existing
The ability of germination period and the disease and insect resistance in seedling stage.
Preferably, the mass ratio of the salicylic acid and the Diacloden is 1:0.8-2.5.
In above-mentioned technical proposal, salicylic dosage it is excessive or it is very few can all influence its efficacy exertion, by many experiments
It was found that obtained Compositional type seed coat agent using effect is best when salicylic acid and Diacloden amount ratio control within the above range.

In above-mentioned technical proposal, containing there are three types of pesticide original medicine and a large amount of dispersing agent and carrier in medicament A, various objects are needed
Matter is uniformly dispersed in carrier, and it is low that aqua or wettable powder will appear solubility, and missible oil causes serious pollution to the environment and insoluble
Yu Shui cannot be mixed with medicament B, so medicament A is preferably made to suspending agent.Main action component is water in medicament B
Poplar acid, is a kind of fat-soluble organic acid, and salicylic acid cannot be added directly into medicament A, because of uncertain ternary built desinsection
Whether the medicament A of agent fungicide will affect salicylic activity, so the present invention, which individually comes out salicylic acid, is made into a kind of dosage form,
Also it is conducive to accurately control salicylic dosage simultaneously, and aqua nonhazardous is made, and the drug effect of raw medicine can be given full play to, moreover it is possible to
Play the role of diluting medicament A (high concentration medicament) when use, so medicament B is preferably made to aqua.

Application examples
Seed pelleting processing: selecting health cotton seeds full, of uniform size, pours into prepared seed coat agent sufficiently
It stirs evenly, every 100 kilograms of seeds are corresponding to use seed coat agent 1-2 liter, can sow after drying in the shade.
Low temperature germination test: by seed sowing in seedling-raising box, matrix is fine sand, is placed in incubator, and the photoperiod is
12h/12h (day night), day night temperature are respectively 20 DEG C/8 DEG C, incubator intensity of illumination 12000lx, and relative humidity 70%~
75%.Here eight groups of tests are carried out, first group is blank control (to seed without any processing), in second group to the 8th group
Seed be coated processing with the seed coat agent in embodiment 1-5, comparative example 1-2 respectively, every group test process 30,3 weights
It is multiple.
Investigation method:
With bud it is long be more than 0.5cm, color is white, non-rot and without negative sense growth bud is normal bud.After planting observation kind
The sub- talent arch soil time counts germination number in after planting the 4th day daily, calculates germination percentage.It emerges in the 12nd day statistics
It counts, and randomly selects 10 plants of cotton seedling of different disposal, measure seedling seedling overall length with graduated scale.
Field trial (is pacified in Henan Province on April 19th, 2018 in experiment station of the Chinese Academy of Agriculture Science and Technologys Cotton Research Institute base
Yang Xian) carry out.In 60 loose types are coated as material to be tested, by cotton seed according to dosage, 2 row areas of each processing, the long 8m of row,
Using randomized complete-block design, 3 repetitions.It is investigated in cotton tri-leaf period, 5 points of samplings, 20 plants every, totally 100 plants, system
A situation arises for meter cotton seedling blight and cotten aphid, and calculates diseased plant rate and leaf roll strain rate.Above-mentioned each investigation result is as shown in table 1.
Table 1 uses the growing state and field disease pest investigation result of the cotton seed of different seed coat agents
