Description
Technical field
The present invention relates to and belong to field biological material being applied to proportion of crop planting, specifically a kind of corn seed coating agent with strong root, strong sprout and water retaining function and preparation method thereof.
Background technology
Semen Maydis, as second-biggest-in-the-world crop, is most important food and feed resource.China is second-biggest-in-the-world Maize Production state, produces Semen Maydis more than 6,750 ten thousand tons per year.Semen Maydis is that China has the call and application one of staple food crop widely.
North of China Spring maize seeding district, based on three provinces in the northeast of China, the Inner Mongol and Ningxia, cultivated area is stable at more than 650 ten thousand hectares, accounts for the whole nation about 36%；Total product more than 2,700 ten thousand tons, accounts for about the 40% of the whole nation.During due to sowing, weather conditions are poor, and particularly drought and water shortage causes that corn seed germination rate is on the low side and seedling growth is weak, thus finally have impact on the yield of Semen Maydis.Therefore how to enable north dry land corn seed after planting have sufficient moisture and nutrition to promote that it is sprouted and seedling growth, be the key improving this area's corn yield.Still lack effective ways to solve this problem at present.
Poly-aspartate is the polymer substance of synthetic, have superpower water retention characteristic and can in soil environment the feature of enriched in nitrogen, phosphorus, potassium and trace element, there is nontoxic, nuisanceless and fully biodegradable characteristic simultaneously, if sprouting and the growth of seed can be transformed and be applied to, then it is likely to play more positive effect.
Summary of the invention
It is an object of the invention to provide a kind of corn seed coating agent with strong root, strong sprout and water retaining function and preparation method thereof.
The technical solution used in the present invention is for achieving the above object:
A kind of corn seed coating agent with strong root, strong sprout and water retaining function, coating materials is made up of poly-aspartate, cross-linking agent and shinyleaf yellowhorn fruit shell powder, and wherein, the weight ratio between poly-aspartate and cross-linking agent is 200:(1～6)；The ratio of shinyleaf yellowhorn fruit shell powder and poly-aspartate is 1:(15～45).
Described poly-aspartate is the water-soluble high-molecular substance formed after biofermentation, chemical polymerization；
Shinyleaf yellowhorn fruit shell powder is fineness is the shinyleaf yellowhorn fruit shell powder of 50-150 order.
A kind of preparation method of the corn seed coating agent with strong root, strong sprout and water retaining function, according to the above ratio poly-aspartate and cross-linking agent are sufficiently mixed and make mixture of viscous form, mixture is spread evenly across corn seed surface, then it is coated with shinyleaf yellowhorn fruit shell powder again, dry, dry when gravity-flow ventilation,.The corn seed coating agent that the present invention obtains, can make the corn seed being planted in arid, semiarid climate Soil Under Conditions obtain more sufficient moisture and nutrient, thus being greatly improved percentage of seedgermination and promoting the growth of Maize Seedlings.
Between described mixture of viscous form and corn seed, mass ratio is 1:(0.5～2).
Described poly-aspartate is the water-soluble high-molecular substance formed after biofermentation, chemical polymerization；
Shinyleaf yellowhorn fruit shell powder is fineness is the shinyleaf yellowhorn fruit shell powder of 50-150 order.Described shinyleaf yellowhorn fruit shell powder is for pulverizing (repeating pulverizing 3～5 times) after 50-150 mesh sieve by shinyleaf yellowhorn shell through pulverizer, stand-by.
Described cross-linking agent is common cross-linking agent, such as ethylenediamine.
Present invention have the advantage that
Coating materials of the present invention utilize superpower Water-saving effect that poly-aspartate has and can enriched in nitrogen, phosphorus, potassium and trace element to supply the feature of plant nutrient, there is without phosphorus, nontoxic, nuisanceless and fully biodegradable characteristic simultaneously, additionally a certain amount of cross-linking agent of proportioning and shell powder make it not only have water retention around corn seed in arid, semi-arid soil, to ensure corn seed germination rate, and there is strong root strong sprout, increase the effect of Semen Maydis resistance, specifically:
1, coating materials of the present invention has the multiple-effects such as water-retention, water conservation, seedling-protection.Around seed, form moistening " little reservoir " there is bigger water absorbing capacity and good water retaining function.Ensure corn seed germination rate.
2, coating materials of the present invention has significant strong root effect.The growth of maize seedling root system can be promoted, grow root system, increase root system fresh material and root system dry.
3, coating materials of the present invention can increase soil root vigor, improves soil enzyme activities, improves ecological environment of soil.
4, coating materials of the present invention has effect in significant strong sprout, dramatically increases that Seedling Height, Ye Kuan, leaf length, stem be thick, stem Fresh Yuxincao and stem quality.
5, coating materials of the present invention improves plant polyphenol oxidase and catalase activity, increases plant resistance.
6, the former employing agricultural wastes-shinyleaf yellowhorn fruit shell of the inventive method, with low cost, resource recycles, yield increase effect is notable.
