Abstract
The invention discloses wax for plant seed pretreatment and a preparation method and an application method thereof. The wax consists of the following components in percentage by weight: 80-90% of wax substances, 10-20% of humectant and 1-2% of bactericide. According to the wax disclosed by the invention, when the soil temperature is lower than the minimum temperature 8-10 DEG C required for plant seed germination, the wax substances form a dense solid protection film which effectively cuts off substance exchange between seeds and the outside to avoid bacterial infection, and the seeds can be protected from frost damage in the low-temperature soil in early spring while seed powder is avoided; when the soil temperature reaches the minimum temperature 8-10 DEG C required for plant seed germination, the wax substances are molten to form a liquid-state hydrophobic protection layer which is adhered to the surface of a plant seed and can inhibit the evaporation of moisture in the plant seed so that the seed contains proper moisture and the seed germination is promoted; after seed germination, the protection film formed by the wax substances is broken through, and the plant growth is not influenced.
Description
One, technical field
The invention belongs to wax work technical field, be specifically related to wax and preparation method thereof and using method for a kind of plant seed pretreatment.
Two, background technology
Corn, soybean, Chinese sorghum, millet are annual gramineae herbaceous plant, are important cereal crops and important feed resource.Begin sowing in good time be make crop from seed sprouting, emerging obtains favourable weather conditions, full stand strong sprout, plant normal growth, ripe important measures in good time to each breeding time of maturation.The sowing optimum period of Different Crop, depends mainly on breediness, temperature, moisture, cropping system, soil property and physical features.The vegetative period of above-mentioned plant is shorter, sows whether suitable the growing and output of crop that directly affect.The temperature range that various crops germinate required is different, and minimum temperature is also different.The germination minimum temperature of corn, soybean, Chinese sorghum, millet is 8～10 ℃, and when 12 ℃ of temperature, 5～10cm ground temperature are stablized by 8～10 ℃, sowing is advisable.Plant seeding have the saying of " in spring every day counts, in summer every hour counts ", " summer sowing is striven early, more early better ".Early sowing in good time has a lot of benefits: the one, and the accumulation of the material that has additional nutrients; The 2nd, be conducive to seedlings root growth; The 3rd, avoid or alleviate soil insect causing harm.But cross planting early enough, plant seed does not germinate under low temperature, under the effect of water, easily cause courses of infection.The capricious area of very cold and spring temperature particularly.Plant is very sensitive to the reaction of temperature, during spring sowing, as low temperature, the unequal factor of drought and waterlogging, causes powder seed to be short of seedling, or after seed sprouting, temperature declines to causing suddenly and freezes seedling, and these factors are very large to the yield effect of plant.
For solving the contradiction between the drawback that benefit that in good time early sowing has and climatic variation may bring, conventionally the seeding technique that adopts top layer plastic film to cover at present, but use top layer plastic film covering can cause air capacity of soils poor, affect the aerobic respiration situation of seed germination, meanwhile, using in a large number mulch film is also the main cause that causes white pollution.Patent CN200910072511.3 discloses a kind of physical root-growth-promotion preparation of rice seedbed seedlings and method, that to take the long-chain materials such as oil or wax be membranous base material, evenly spray on kind of bed, then sowing, the method has been improved seedling development oxygen status, but also need excessive use, long-term use meeting brings many adverse effects to soil.
Three, summary of the invention
The object of this invention is to provide a kind of suitable phase transition temperature that has, can be used for the front pretreatment of plant seed sowing, make plant early sowing in good time, avoid plastic film to cover and spray wax and preparation method thereof and the using method for plant seed pretreatment of many deficiencies that kind of bed brings.
For achieving the above object, the technical solution used in the present invention is: this pretreatment is comprised of following compositions and percentage by weight thereof with wax: Wax 80%-90%; Humectant 10%-20%; Bactericide 1%-2%; Above-mentioned each component percentage by weight sum is 100%.
The phase transition temperature of above-mentioned Wax is 5-7 ℃, and wherein normal paraffin content is more than 90%.
Above-mentioned humectant is dihydroxylic alcohols and/or polyalcohol.
Above-mentioned bactericide is metconazole and/or cyazofamid.
Pretreatment of the present invention by the preparation method of wax is: take by weight percentage each component, be at room temperature stirred to and mix and get final product.
Pretreatment of the present invention by the using method of wax is: the plant seed of processing according to a conventional method at room temperature immerses this pretreatment with in wax; filter and remove after unnecessary wax liquid; plant seed is placed in to the cold storage plant of 0 ℃ 0 ± 1 ℃; until the surface of the seed wax liquid, be frozen into after fine and close diaphragm, can sow according to a conventional method.
Above-mentioned plant seed comprises corn seed, soya seeds, jowar seed or Millet Seed.
Seed pretreatment wax of the present invention, select Wax, humectant and bactericide that phase transition temperature is suitable as the main component of inorganic agent, at soil temperature during lower than 8～10 ℃ of the required minimum temperature of plant seed germination, Wax forms fine and close solid diaphragm, effectively blocking-up seed and extraneous mass exchange, avoid courses of infection, and early spring low temperature soil can protect seed not to be damaged by frost, not powder seed, so comparable normal sowing dates can shift to an earlier date (ground temperature is stabilized in 2 ℃ and can sows) about 10 days; When soil temperature reaches 8～10 ℃ of the required minimum temperature of plant seed germination, Wax fusing, forms liquid hydrophobic protective layer and sticks to plant seed surface, can suppress the moisture transpiration in plant seed, make seed contain suitable moisture, promote seed sprouting; After seed sprouting, break through the diaphragm that Wax forms, can not affect the growth of plant; After seed sprouting, if environmental temperature declines suddenly, Wax solidifies again, discharges certain heat in the time of 5～7 ℃, can effectively alleviate the adverse effect that environmental temperature declines plant seed is brought.The selected material of the present invention can not produce injury or impact to the surface of the seed, and can play a protective role.Meanwhile, because seed pretreatment of the present invention is less with wax consumption, and can natural degradation, long-term use can not damage soil and environment.Plant seed is sowed after pretreatment of the present invention, is the effective measures that drought resisting is prevented waterlogging again, can sow ahead of time, increases number of growing days, can premature ripening 5～6 days, improved agricultural performance.
