Description
Technical field
The present invention relates to the antifreeze field of plant, particularly relate to a kind of Plant antifreezer and preparation method thereof.
Background technology
In northern China, often occur that the injuries of surviving the winter such as trees experience freeze injury cause dry slightly even dead phenomenon.Introduce in cultivation also there will be Similar Problems in Chinese chestnut, fruit tree such as hybridization fibert, apple etc.Also usually can there is Bud Cold Damage in apricot pear tree etc. in spring cold in the late spring.Except by except the strong improved seeds of seed selection frost resistance, also need suitably to adopt the antifreezing measures of trees to carry out integrated control.
Existing trees means to prevent freezing mainly contain physics antifreeze and use Plant antifreezer.Adopt trunk parcel straw screen or mat to comparatively cold area majority, straw screen or mat wraps up Polypropylence Sheet outward again and carries out antifreeze, this mode troublesome poeration, and labour intensity is large, and also needs spring in the coming year to take apart again, causes the wasting of resources comparatively serious.Using the traditional approach of Plant antifreezer to whitewash limb for using lime to add lime sulfur, the injury that sunny slope skin zone is subject to because day and night temperature is excessive can be reduced, and some damage by disease and insect of surviving the winter can be killed.Whitewash the time generally between late October to mid-November, can not delay the time of whitewashing, the too low meeting of temperature causes whitewashes material fall in flakes.After trunk whitewashing, decrease and set the absorption of body to solar thermal energy early spring, reduce the speed that tree temperature promotes, tree body can be made to sprout and postpone 2-3d, thus effectively prevent from setting the frost that body meets with Hui Han in early spring.To the seeds that bud is sprouted early, carry out trunk and whitewash, also can late blooming, to avoid the harm of late frost.Also there are some other antifreezing agents in prior art, but substantially all have harmful effect to environment.In view of the problems referred to above of prior art, need to develop a kind of proportioning simple, easy to use, significantly can reduce the freeze injury loss of trees, a kind of preparation and method preventing plant frozen injury of good freezing protection effect.
Based on the above-mentioned defect of prior art, propose the present invention.
