Problems solved by technology

[0003] The purpose of the present invention is to solve the problem of seed powder, chilling injury death 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 a delay of 10-15 days in maturity, resulting in a substantial reduction in production. The problem of quality decline, and provide a kind of cold and drought resistant seed coating agent and a kind of cold resistant spray

specific Embodiment approach 1

[0006] 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.

[0007] 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.

[0008] Comparative Experiment:

[0009] 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

[0011] 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

[0012] 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

The invention relates to a cold resistant packing agent, wherein it comprises 5-50% cold resistant nutrient, 10-70% macromolecule water absorber, 0.1-10% disinfector, 0.1-10% antiseptic, 0.01-2% growth adjuster, 0.02-2% cold resistant nutrient, and 0.2-20% oxygen releaser. And the cold resistant sprayer comprises 30-80% cold resistant nutrient, 4-40% cold resistant liquid, 0.02-2. 0% surface activator, 0.001-1. 0% plant growth adjuster and left water. The invention can seed at low temperature. And the cold resistant sprayer can improve the cold resistance of plant / .

Description

technical field [0001] The invention relates to a seed coating agent and a spraying agent. Background technique [0002] 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 slurry water accumulated in the permafrost layer will evaporate soon Exhausted, the seeds will be difficult to germinate due to lack of water. However, when crop seedlings encounter cold currents, delayed chilling damage will occur, leading to a delay in maturity, resulting in a substantial reduction in producti...
