Abstract
The invention discloses a low-temperature protective agent for vegetables. The low-temperature protective agent is prepared from the following components in parts by weight: 1.5-4.5 parts of multivita-glucose, 0.5-2.5 parts of choline chloride, 0.1-1.5 parts of calcium chloride, 0.1-0.5 part of tea saponin, 0.05-0.35 part of chlormequat chloride, 0.05-0.25 part of plant antifreeze protein, 0.01-0.04 part of glycerinum, 0.02-0.05 part of a film-forming agent and 95-98 parts of distilled water. The low-temperature protective agent for vegetables disclosed by the invention is capable of preventing and retarding loss of the vegetables caused by low temperature, and is simple, feasible, relatively low in cost, and significant in low-temperature resistance.
Description
Technical field
The present invention relates to a kind of vegetable cryoprotective agent, belong to field of crop production.
Background technology
Winter-spring season utilizes facility cultivation vegetables, will damage to plants caused by sudden drop in temperature or freeze injury when the useful lower temperature limits of ambient temperature lower than vegetables normal growth, show as following several respects: (1) blade is injured: being injured at cotyledon period shows as cotyledon margin chlorosis, occur " white edging ", as short-term low temperature or cold wind invasion and attack after field planting, the influenced meeting of plant part blade edge, in dirty-green, is then dried up gradually; (2) root system is injured: show as root growth and stop, can not occurring newly to follow, and the old root of part starts jaundice, dead gradually.Even if temperature is gone up very soon, plant also can show wilting growth rate and slow down; (3) growing point is injured: when comparatively serious freeze injury occurs, terminal bud is endured cold, and does not send out young leaves; (4) flowers and fruits are injured: vegetables meet the impact of microthermal climate in flowering stage, and Pollination Fertilization rate reduces, and can form a large amount of fruit drops or malformed fruit after a while.
At present, in vegetable production in green house, the measure of anti-low temperature is taked to have: (1) adopts kind that is low temperature resistant, the low light level; (2) take facility inside holding, add the gentle impact increasing the measures such as illumination and to slow down low temperature, facilities vegetable is grown; (3) adopt suitable field management measure to alleviate low temperature to the impact of facilities vegetable, as adopt bilayer, multilayer to cover method, adopt the way of many organic fertilizers and adopt drip irrigation technique to reduce each irrigation amount to prevent the measures such as reduction ground temperature; (4) adopt foliage spray growth regulator, change the physiological property of vegetables, strengthen anti-low temperature function.Above-mentioned anti-low temperature measure can play a role to a certain extent, but still there is the problems such as cost of investment is high, use complexity is dangerous, effect is unstable.
Summary of the invention
The technical problem solved: for the deficiencies in the prior art, the invention provides a kind of vegetable cryoprotective agent, can prevent and slow down the loss that low temperature causes vegetables, simple, cost is lower, and anti-cryogenic effect is remarkable.
Technical scheme: a kind of vegetable cryoprotective agent provided by the invention; be made up of the component of following parts by weight: multivita-glucose 1.5 ~ 4.5 parts; Choline Chloride 0.5 ~ 2.5 part; 0.1 ~ 1.5 part, calcium chloride, Tea Saponin 0.1 ~ 0.5 part, chlormequat 0.05 ~ 0.35 part; plant antifreeze protein 0.05 ~ 0.25 part; glycerine 0.01 ~ 0.04 part, film forming agent 0.02 ~ 0.05 part, distilled water 95 ~ 98 parts.
Described Tea Saponin is the excellent auxiliary agent of aqua or soluble powder agricultural chemicals, can improve the physical property of agricultural chemicals, improves liquid at the adhesive force of plant surface, plays the synergistic effect to agricultural chemicals, saponin content >=30wt%.
Described plant antifreeze protein is the one in carrot, perennial ryegrass, winter rye albumen; Described film forming agent is the one in carboxymethyl cellulose, gum Arabic, gelatin, xanthans, starch.
Beneficial effect: vegetable cryoprotective agent provided by the invention, (1) is avoided suffering cold in the late spring in spring, autumn frost and ice and snow to the damage of vegetables, prevention low temperature freezing-disaster; (2) cover crop is subject to not to be subject to freeze injury during the critical point temperature decline 3 ~ 8 degree of freeze injury; (3) reducing vegetables can not Growth and anthesis result or poor growth phenomenon because of low temperature; (4) immunity and the safety of vegetables is improved.
