For solving the contradiction between benefit that in good time early sowing has and the drawback that climatic variation may bring, usually the seeding technique of top layer covered rearing with plastic film is adopted at present, but use top layer covered rearing with plastic film that air capacity of soils can be caused poor, affect the aerobic respiration situation of seed germination, meanwhile, a large amount of use mulch film is also the main cause causing white pollution.Patent CN200910072511.3 discloses a kind of physical root-growth-promotion preparation of rice seedbed seedlings and method, for film quality base material with long-chain materials such as oil or waxs, evenly spray on kind of bed, then sow, the method improve seedling development oxygen status, but also need excessive use, Long-Time Service can bring many adverse effects to soil.
Three, summary of the invention
The object of this invention is to provide and a kind of there is suitable phase transition temperature, can be used for the front pretreatment of plant seed sowing, enable plant early sowing in good time, avoid covered rearing with plastic film and the plant seed pretreatment wax spraying many deficiencies that kind of bed brings and preparation method thereof and using method.
For achieving the above object, the technical solution used in the present invention is: this pretreatment wax is made up of following compositions and percentage by weight thereof: hydrocarbons 85%-90%; Humectant 10%-15%; Bactericide 0.1%-2%; Above-mentioned each component percentage by weight sum is 100%.
The phase transition temperature of above-mentioned hydrocarbons is 5-7 DEG C, and wherein normal paraffin content is more than 95%.
Above-mentioned humectant is dihydroxylic alcohols and/or polyalcohol.
Above-mentioned bactericide is metconazole and/or cyazofamid.
The preparation method of pretreatment wax of the present invention is: take each component by weight percentage, is at room temperature stirred to and mixes and get final product.
The using method of pretreatment wax of the present invention is: the plant seed processed according to a conventional method at room temperature immerses in this pretreatment wax; filter after removing unnecessary wax liquid; seed is placed in the cold storage plant of 0 ± 1 DEG C; be frozen into after fine and close diaphragm until the surface of the seed wax liquid, put into the papery overpack stored under refrigeration extremely sowing that proper proportion chemical fertilizer is housed.
Above-mentioned plant seed comprises corn seed, soya seeds, jowar seed or Millet Seed.
The chemical fertilizer that above-mentioned papery overpack has been equipped with can be in nitrogen, phosphorus or the potash fertilizer such as potassium dihydrogen phosphate, ammonium dihydrogen phosphate (ADP), urea one or more; The ratio of various chemical fertilizer, can determine according to the soil fertility height of ploughing.
Hydrocarbons, humectant and the bactericide that phase transition temperature is suitable selected by pretreatment wax of the present invention; it is the main matter of protection corn seed; when lower than minimum temperature needed for seed sprouting 8 ~ 10 DEG C of soil temperature; hydrocarbons forms fine and close solid diaphragm; effective blocking-up seed and extraneous mass exchange; avoid infection process; and early spring low temperature soil seed can be protected not to be damaged by frost; not powder seed, therefore comparable normal sowing dates can shift to an earlier date about 10 days (ground temperature is stabilized in 2 DEG C and can sows).When soil temperature reaches 8 ~ 10 DEG C of minimum temperature needed for seed sprouting, hydrocarbons melts, and is adsorbed in external packing made of paper, form the protective layer that hydrophobicity is suitable, the moisture transpiration in seed can be reduced, do not affect again the water in the neutron absorption external world and various nutrient, promote seed sprouting; Meanwhile, hydrocarbons needs absorb or discharge more heat in fusing or process of setting, and during can reducing seed sprouting, environmental temperature declines suddenly the adverse effect brought.After seed sprouting, break through external packing made of paper, the growth of plant can not be affected.During seed sprouting, if environmental temperature declines suddenly, hydrocarbons solidifies again, 5 ~ 7 DEG C time, discharge certain heat, effectively can alleviate environmental temperature and to decline the adverse effect brought seed.Material selected by the present invention all can not produce injury or impact to the surface of the seed, and can play a protective role.Meanwhile, because pretreatment wax consumption of the present invention is less, and can natural degradation, Long-Time Service 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 sows ahead of time, increases number of growing days, can premature ripening 5 ~ 6 days, improves agricultural performance.
