Problems solved by technology

[0004] The purpose of the present invention is to solve the problem of seed powder, death of chilling injury and difficulty in germination due to lack of water under low temperature conditions, and delayed chilling injury will occur when crop seedlings encounter cold currents, resulting in delayed maturity of 10 to 15 days, resulting in a substantial reduction in production and food production. degraded quality, and a cold-resistant spray provided

specific Embodiment approach 1

[0007] Specific Embodiment 1: In this embodiment, the cold-resistant and drought-resistant seed coating agent consists of 5% to 50% of cold-resistant nutrients, 10% to 70% of polymer water-absorbing agent, 0.1% to 10% of bactericide, and 0.1% ~10% preservative, 0.01%~2% plant growth regulator, 0.02%~2% penetrant and 0.2%~20% oxygen release agent.

[0008] Put 20 g of the anti-cold and drought-resistant seed coating agent of this embodiment into 1 kg of water, swell into a hydrogel, add 10 kg of seeds and stir, mix the seeds and dry them before sowing in the field.

[0009] Comparative Experiment:

[0010] Sow the 3 groups of corn seeds treated with the cold-resistant and drought-resistant seed coating agent and the 3 groups of untreated corn seeds in an environment with a water content of 21% and -3°C to 7°C, and raise the temperature to 15°C to 22°C after 72 hours After emergence, the emergence rate, plant fresh weight, root fresh weight and root length were counted. The st...

specific Embodiment approach 2

[0013] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is: the anti-cold and drought-resistant seed coating agent consists of 10% to 45% of cold-resistant nutrients, 20% to 60% of polymer water-absorbing agent, 1 %~8% fungicide, 1%~8% preservative, 0.1%~1.5% plant growth regulator, 0.1%~1.5% penetrant and 0.5%~18% oxygen release agent.

specific Embodiment approach 3

[0014] Specific embodiment three: The difference between this embodiment and specific embodiment one is: the cold-resistant and drought-resistant seed coating agent consists of 41% cold-resistant nutrients, 54% polymer water-absorbing agent, 1% fungicide, 1 % preservative, 0.8% plant growth regulator, 0.2% penetrant and 2% oxygen release agent.

Abstract

A cold-resistant sprayer agent relates to a sprayer agent, which solves the problems of maturation period delay, output reduction and grain quality decline resulting from powder seeds under a low temperature condition, chilling injury death, difficult germination and delayed chilling injury in case of encountering the cold current in the seedling stage. The cold resistant sprayer agent is prepared by the weight percent as follows: 30%-80% of cold resistant nutriment, 4%-40% of antifreeze liquid, 0.02%-2.0% of surfactant, 0.001%-1.0% of plant growth regulator and water of the rest. The cold-resistant sprayer improves the cold resistance of the plant at a molecular level and is capable of reducing the mechanical damage formed by the ice crystal in the protoplasm at a low temperature.

Description

[0001] The patent application of the present invention is a divisional application separated from the invention patent with the application number 200610151161.6, the application date is December 19, 2006, and the invention name is "a kind of anti-cold and drought-resistant seed coating agent and a kind of anti-cold spray agent" . technical field [0002] The present invention relates to a spray agent. Background technique [0003] Northern China accounts for one-half of the country's arable land. Due to the cold climate and short frost-free period, other field crops except spring wheat cannot be sown in early spring with low temperature and moisture retention (returning pulp and water to preserve moisture). Imbibulous or germinated seeds in the soil under low temperature conditions are likely to cause powder seeds due to the action of microorganisms, or die due to cold damage; if there is insufficient rain in spring, if the seeds are planted too late in winter, the returned...
