Technical Field

The invention belongs to the technical field of agriculture, and particularly relates to fruit tree cold-proof and anti-freezing solutions and application thereof in cold and freeze proofing of fruit trees.

Background

In subtropical humid monsoon climate regions, especially in areas in the southeast coast of south China, the temperature is variable, and the temperature difference between day and night is large.

Subtropical fruit trees such as longan, litchi, loquat and the like have poor cold resistance and are not frost-resistant, and when the temperature is lower than 8 ℃, cell division activity is in a basic stagnation state to resist stress by a short dormancy peculiar to plants. Slight cold injury can occur at 4-8 deg.C. However, when the temperature is below 5 ℃ for a long time, sporadic yellow frostbite can occur on leaves, and buds, tender shoots and even partial mature shoots can be frostbitten and killed.

The measures for preventing the fruit trees from being frozen mainly comprise a ① covering and heat preserving method, a plastic film, a sunshade net, a grass felt and the like are used for covering the whole plants, particularly seedlings, soil can be planted at the base part to protect the root systems, the plants are prevented from being in direct contact with cold air, frost, fog, ice and the like, a ② trunk whitewashing method is adopted, common anti-freezing measures are adopted, the current anti-freezing measures are commonly used for south-north fruit trees, the root systems can not be whitewashed by the tree due to the fact that the trunk whitewashing can not be whitewashed by the tree, branches on a frame are not whitewashed by adopting a trunk whitewashing mode, photosynthesis is not influenced, side effects are generated, a whitewashing agent is prepared by 10 parts of quicklime, 1 part of sulfur powder, 1 part of salt, 0.1 part of vegetable oil and 20 parts of clear water, a ③ smoking method is adopted, when frost, the method is adopted, a fire piles can be burned, dry firewood can be put on dry plants, moist straws and the like, heat and smoke are generated, the root system can be used for supplementing, the root system can be used for the root system after the dry straw is burnt, the straw is used for preventing soil, the straw moisture and the straw soil is used for the straw soil, the straw is used for the root system can be recovered, the straw trees, the straw is used for the straw trees, the straw system can be used for the straw trees, the straw system can be used for preventing the straw system can be used for the.

The measures have definite effects on preventing the freezing injury of the fruit trees, but the effects are obviously different in different regions and different climatic conditions, and in addition, the measures need a large amount of labor and time, and are labor-consuming to operate, and the measures cannot be quickly implemented to protect the fruit trees in the whole orchard when the air temperature suddenly drops.

Disclosure of Invention

Therefore, fruit tree cold-proof and anti-freezing solutions capable of quickly, simply and conveniently preventing the freezing injury of fruit trees are needed to be provided, and the cold-proof and anti-freezing solutions can be quickly applied to the fruit trees in the whole orchard before the temperature suddenly drops, so that the cold-proof and anti-freezing effects are achieved.

In order to achieve the purpose, the inventor provides the following technical scheme:

fruit tree cold-proof and anti-freezing liquid, the effective components of which include more than two of diethyl aminoethyl hexanoate, algin foliar fertilizer and potassium dihydrogen phosphate.

, the cold-proof and anti-freezing liquid is prepared from diethyl aminoethyl hexanoate, algin leaf fertilizer, potassium dihydrogen phosphate and water in a mass ratio of 1 (40-60) to (4 x 10)⁴-6×10⁴). The preparation method comprises the steps of 1 part of diethyl aminoethyl hexanoate pure raw medicine, 40-60 parts of algin foliar fertilizer, 40-60 parts of monopotassium phosphate and 4-6 ten thousand parts of water, and stirring until the materials are completely dissolved.

, the fruit tree cold-proof and anti-freezing liquid is applied to fruit tree cold-proof and anti-freezing.

The application method is that when the future temperature of the weather forecast is lower than 3-5 ℃, or 2-3 days before cold tide comes, the fruit tree cold-proof and anti-freezing liquid is uniformly sprayed on the whole body of the fruit tree, including the front and back surfaces of the branches and the leaves, and times of spraying can be repeated at intervals of 5-6 days.

The spraying amount of the cold-proof anti-freezing liquid is determined according to the size of a tree body, 1.2-1.3kg of anti-freezing liquid is sprayed on each tree of a three-year-old fruit tree, 2.0-2.5kg of anti-freezing liquid is sprayed on each tree of a five-year-old fruit tree, and 4.5-5.5kg of anti-freezing liquid is sprayed on each tree of an eight-year-old fruit tree.

The fruit trees are subtropical fruit trees, including citrus trees, longan trees, litchi trees, banana trees, loquat trees or dragon fruit trees.

The invention has the beneficial effects that:

(1) the invention solves the problems that the fruit trees are frozen to cause the death of the trees or the weak growth vigor of the trees under the condition of continuous low temperature or extremely low temperature, so that the yield of the fruit trees in the next year is low and the like.

(2) The cold-proof and anti-freezing liquid is simple to prepare, low in cost and remarkable in cold-proof and anti-freezing effects of fruit trees.

(3) The invention can effectively prevent the fruit trees from being frostbitten, obviously reduce the death rate, and enhance the disease resistance of the plants, so that the plants have better overall growth vigor and high yield, and the economic benefit is improved.

(4) The cold-proof anti-freezing liquid is simple to use, is sprayed by a self-suction pesticide sprayer, is convenient to operate, has long shooting range and high efficiency, and is time-saving and labor-saving.
