Description
Technical field
The present invention relates to kind clothing agent and a kind of spray agent.
Background technology
The China north accounts for national arable area 1/2nd, and because of weather cold, frost-free season is short, other field crop except that spring wheat can not early spring low temperature lose no time in sowing while there is sufficient moisture in the soil (rob return pulp-water preserve soil moisture) sow.Under the condition of low temperature in the soil imbibition or the seed of sprouting because action of microorganisms easily causes the powder kind, or because of damaging to plants caused by sudden drop in temperature death; Spring the rainwater deficiency, if sow be collected in frozen soil layer too late winter return that just pulp-water is very fast can be evaporated totally, seed can be difficult to sprout because of lack of water.And crops seedling stage is met cold current and retardance can take place damaged to plants caused by sudden drop in temperature, and causes the maturing stage to be postponed, and causes the underproduction significantly, and grain quality descends.
Summary of the invention
The objective of the invention is for seed meal kind under the condition that solves low temperature, damage to plants caused by sudden drop in temperature death and be difficult to sprout and crops seedling stage is met cold current and retardance can take place damaged to plants caused by sudden drop in temperature because of lack of water, cause the maturing stage to be postponed 10～15 days, cause the underproduction significantly, the problem that grain quality descends, and a kind of cold-resistant draught-resistant seed coating agent that provides and a kind of cold-resistance spraying agent.Cold-resistant draught-resistant seed coating agent is made by 5%～50% cold-resistant nutrient, 10%～70% polymer water-absorbent, 0.1%～10% bactericide, 0.1%～10% preservative, 0.01%～2% plant growth regulator, 0.02%～2% bleeding agent and 0.2%～20% oxygen release agent by mass percentage.Cold-resistance spraying agent is made by 30%～80% cold-resistant nutrient, 4%～40% anti frozen liquid, 0.02%～2.0% surfactant, 0.001%～1.0% plant growth regulator and the water of surplus by mass percentage.
The cold-resistant draught-resistant seed coating agent of the present invention has suction, water conservation, extraneous root, cold-resistant, sterilization and corrosion-resistant effect, guarantee seed in low temperature environment not the powder kind, do not go rotten, when rising, soil temperature emerges as usual, effectively raise the ability of the cold-resistant and drought resisting of seed, do not postpone the maturing stage, have laid a good foundation for the high yields of crops increases income.
The rapid decline of temperature causes on the phytoplasm film and the bigger non-lipid space of saturating property to occur, and cell content matter is free permeation and cause cell death thus.Cold-resistance spraying agent of the present invention has strengthened the cold tolerance of plant from molecular level, also can reduce and form the mechanical damage of ice crystal under the low temperature in the protoplasm the film system, strengthen the cold tolerance of seedling and young leaves, do not postpone the maturing stage, established good base and go out for the high yields of crops increases income.
