Description

A kind of tea tree antifreezing agent and preparation method thereof
Technical field
The invention belongs to Plant antifreezer technical field, and in particular to a kind of tea tree antifreezing agent and preparation method thereof.
Background technology
When early spring temperature over the years is mutated, the lighter causes the underproduction for crops freeze injury, heavy then have no harvest.
Southern Jiangsu tea area includes peaceful township domain（Nanjing, Zhengjiang City）With Su Xichang regions（Suzhou City, Wuxi City, Changzhou City）.Tea tree breed successively introduces nonlocal breeding based on local leaflet kind.Because southern Jiangsu tea area early spring temperature shows Unstability, first warm up and first tremble with fear, along with daily temperature range is big, Late frost weather often occurs, and is caused damage to tea place.Tea tree it So by freeze injury be due to caused by low temperature cell or tissue freeze and it is aggrieved.Low temperature is condition, is external cause, and cell or group Knit to freeze and be only the internal cause of freeze injury.When temperature is down to zero it is following when, tea tree space between cells moisture starts to freeze, now if after Continuous cooling, intracellular cell Free water are permeated also with icing, cellular contraction, cell moisture to space between cells, and cell liquid is dense Degree increase, cause plasm dehydration, solidify and lose vigor, it is then dead.
Research in terms of the spring Spring frost of tea place at present, mainly from breeding high frost resistance tea tree breed, Spring frost Remedial measure after precautionary measures and freeze injury is studied.The precautionary measures of freeze injury mainly from tea place covering and heat insulating measure, are adjusted with water Warm moist keeping measures, fumigation are dispeled cold measure, fan practice of frost protection.Directly existed using materials such as sunshade net, straw, films before frost Tea clump surface or built are covered to prevent spring Spring frost from having certain effect；But these technologies need certain facility, into This is higher, and some labor intensity is big, or even also pollutes the environment.Therefore, develop a kind of easy-to-use blade face antifreezing agent for It is significant to prevent and treat tea tree Spring frost.
The content of the invention
It is an object of the invention to provide a kind of tea tree antifreezing agent suitable for southern area of Jiangsu Province tea place spring Spring frost and its Preparation method, the antifreezing agent can effectively prevent freeze injury.
