Abstract

The invention discloses compound anti-freezing liquid for vegetables and a preparation method thereof. The compound anti-freezing liquid is prepared from the following components: 50 to 70 parts of tea seed meal, 140 to 180 parts of biogas liquid, 15 to 20 parts of a plant growth regulator, 30 to 50 parts of polyglutamic acid, 5 to 8 parts of rare-earth micro-fertilizer, 20 to 35 parts of fulvic acid, 10 to 15 parts of a microelement additive, 8 to 12 parts of choline chloride, 16 to 20 parts of silicon fertilizer and 12 to 18 parts of polyethylene glycol 200. The compound anti-freezing liquidprepared by the preparation method is mainly applied when the temperature is 10 to 15 DEG C in late autumn, early winter and late spring coldness, and can be used for preventing the vegetables from freezing injuries after being applied; normal growth of the vegetables during an anti-freezing period is protected, and the photosynthesis time of the vegetables can be prolonged; meanwhile, various nutrient elements are provided for the vegetables and the vegetables are prevented from being invaded by external diseases.

Description

technical field

[0001] The invention belongs to the technical field of agriculture, and in particular relates to a plant compound antifreeze liquid and its preparation method and use. Background technique

[0002] In recent years, extreme climates have occurred frequently, and southern my country has encountered "cold winters" several times, and the high humidity has exacerbated the cold. Despite the protection of greenhouses, vegetables are not only vulnerable to freezing damage in low-temperature, high-humidity, and low-light environments, but also grow. It is blocked, and it is easy to be infected with diseases and insect pests, which greatly affects the yield and quality of vegetables. Therefore, the insulation and antifreeze measures for overwintering vegetables are particularly important. When late autumn is approaching, in order to improve the antifreeze ability of vegetables, it is generally temporarily heated, covered with plastic film, strengthened fertilizer and w...

Examples

Embodiment 1

[0020] A vegetable compound antifreeze liquid consists of the following raw materials in parts by weight:

[0021] 60 parts of tea meal, 160 parts of biogas slurry, 12 parts of abscisic acid, 6 parts of gibberellin, 42 parts of polyglutamic acid, 7 parts of rare earth fertilizer, 22 parts of fulvic acid, 12 parts of trace element additives, choline chloride 10 parts, 18 parts of silicon fertilizer and 20015 parts of polyethylene glycol.

[0022] The trace element additive is a compound of sodium molybdate, EDTA chelated manganese and borax, wherein the weight ratio of sodium molybdate, EDTA chelated manganese and borax is 3:3:1.

[0023] The preparation method of above-mentioned vegetable composite antifreeze comprises the following steps:

[0024] (1) Transport the biogas slurry to the sedimentation tank for multi-stage sedimentation and filtration to obtain the clear liquid of the biogas slurry for standby;

[0025] (2) Grind the tea meal into powder, wrap it in a non-wove...
