Abstract
The invention discloses a special antifreezing agent for walnut saplings, which consists of water and polyvinyl alcohol, wherein the water is a liquid phase medium of the antifreezing agent, and the adding ratio of the water to the polyvinyl alcohol is 15-20: 1. The antifreezing agent is suitable for preventing freeze injury of young 1-3 year old walnut trees, and has the advantages of obvious antifreezing effect, long lasting time, simple preparation method, high biological safety and obvious economic benefit.
Description
Technical field
The present invention relates to a kind of antifreezing agent, refer in particular to the special-purpose antifreezing agent of a kind of walnut treelet.
Background technology
Antifreezing agent is again antifreeze, is applied to can significantly improve on all kinds of plants green plants and each planting fruit-trees, the disease-resistant anti-low temperature of nursery stock, the freezing tolerance of cold in the late spring, prevents that effectively early late frost attacks, and avoids or alleviate being subjected to freeze injury.Be applied at present the synthetics that mostly is on fruit tree, cost is high, and material stability is low, and general for walnut treelet antifreezing effect.
Hebei province is traditional walnut producing region, and cultivation history is long, is about more than 7000 year according to the unearthed walnut fossil in textual criticism magnetic mountain, Wuan City, and famous crossdrift walnut originates from the Lulong, Hebei in history.At present, there is thousands of a century to give birth to above walnut in the borders of the county such as She County, Laiyuan, Lulong.Taihang Mountain walnut area under cultivation in 2007 is more than 870,000 mu, 40273 tons of gross yields; Hebei province's walnut area under cultivation in 2011 is 14.4 ten thousand hm
2(2,200,000 mu), 9.69 ten thousand tons of output.But, the generation of walnut freeze injury is seriously restricting the development of our province Walnut Industry, especially the She County in Handan, Hebei, to the north of Wuan, the walnut treelet often suffers freeze injury in the winter time, the Second Year stripping is serious, even whole strain is freezed to death, and the freeze injury in time of the year when autumn changes into winter in 2009 makes Hebei province's walnut nursery stock cold mortality reach 70%.Therefore, produce at present the special-purpose antifreezing agent of upper new and effective walnut treelet in the urgent need to pre-frost damage prevention.
Summary of the invention
The technical problem to be solved in the present invention is: disclose the special-purpose antifreezing agent of a kind of novel, efficient walnut treelet, with the reply walnut treelet difficult problem of surviving the winter winter, for the development of China's Walnut Industry provides powerful guarantee.
The technical solution adopted for the present invention to solve the technical problems is: the special-purpose antifreezing agent of a kind of walnut treelet, formed by water and polyvinyl alcohol, and the interpolation proportioning of water and polyvinyl alcohol is 15～20: 1.The liquid phase medium of the special-purpose antifreezing agent of this walnut treelet is water.
The preparation method of the special-purpose antifreezing agent of walnut treelet is: will mix according to two kinds of compositions of said ratio, then boil, namely obtain finished product.
The invention has the beneficial effects as follows: the special-purpose antifreezing agent of this walnut treelet is specially adapted for walnut treelet preventing freeze in winter.This antifreezing agent antifreezing effect is obvious, and efficiency time is long, and the preparation method is simple, biological safety is high, remarkable in economical benefits.
Embodiment
The special-purpose antifreezing agent of a kind of walnut treelet is comprised of water and polyvinyl alcohol, and the interpolation proportioning of water and polyvinyl alcohol is 15～20: 1.
The preparation method of the special-purpose antifreezing agent of walnut treelet is: will mix according to two kinds of compositions of said ratio, then boil, namely obtain finished product.
Below list the embodiment of the special-purpose antifreezing agent of walnut treelet of preparation.
Embodiment one: the different regions result of the test
Embodiment two: the impact of different disposal method on survival rate
As can be seen from the above table: the autumn plants not to be coated with and does and be coated with the dry treatment significant difference, shows that the autumn cultivation is not coated with dried winter protection weak effect, and survival rate is minimum, can not satisfy need of production.
Embodiment three: the different disposal method is drained the impact of height on the walnut treelet
Described test is the ratio situation of draining highly shared whole height overall after the early April rudiment of walnut treelet, as can be seen from the above table: the autumn cultivation is not coated with the dry treatment treelet and drains highly long, have a strong impact on the normal shaping of treelet, extremely significantly be longer than and be coated with dry treatment autumn, reason is to plant the alternate freezing and thawing of rear trunk through a winter autumn, cause serious dehydration, Tu Ganhou forms one deck water conservation film on trunk, has stoped scattering and disappearing of moisture.
Claims (2)
1. the special-purpose antifreezing agent of walnut treelet, is characterized in that, the special-purpose antifreezing agent of described walnut treelet is comprised of water and polyvinyl alcohol, and the interpolation proportioning of water and polyvinyl alcohol is 15～20: 1.
2. the special-purpose antifreezing agent of a kind of walnut treelet as claimed in claim 1, is characterized in that, the liquid phase medium of the special-purpose antifreezing agent of described walnut treelet is water.
