Technical Field
The invention relates to the field of fruit and vegetable sunburn preventing complexes, in particular to a rosin-based metal complex and application thereof.
Background
China is one of the important native areas of citrus, and the citrus has abundant resources, various excellent varieties and more than 4000 years of cultivation history. In recent years, the citrus planting area of China is enlarged year by year, and the annual rate of growth is close to 3%.
In the southwest citrus producing area of China, the damage of sunscald diseases rises year by year under the influence of high-temperature weather, particularly in the noon and afternoon of the high-temperature weather, the local temperature of citrus trees directly irradiated by sunlight rises sharply, when the temperature rises to be more than 40 ℃, chlorophyll of leaves is gradually decomposed, the color of the leaves becomes light or yellow, a large amount of leaves fall after rain, and if the local temperature is too high and air is dried and evaporated too fast, local cell death leaves can generate a local scorching phenomenon. The fruit surface has abnormal color, such as scorched yellow or browned color, and the color change part has sunken peel and hardened. The sunscald seriously affects the appearance of citrus fruits and even causes serious consequences such as fruit drop.
At present, in the actual production process, the sun protection agent is mainly used for preventing the sunscald of the citrus in the modes of manual bagging or smearing a whitening agent (mostly calcium carbonate) and the like, the time and the labor are wasted, and the good sun protection effect is difficult to obtain. In the prior art 1, the citrus sun-proof and sun-proof material is prepared from light calcium carbonate, an ultraviolet blocking agent, surfactant, paraffin oil and the like, and the formula of the material contains a large amount of light calcium carbonate, and the material is easy to precipitate and agglomerate due to high density of the light calcium carbonate, so that the use is influenced; in the prior art 2, a sodium polyacrylate solution and sodium carbonate are mixed, a calcium chloride aqueous solution, a polyacrylic acid component in a formula and the ordinary industrial glue are added, and the material is used for sun protection of oranges, is difficult to completely decolor in the later period, and the surfaces of the oranges often have white residues which are difficult to remove, so that the appearance and the quality of the oranges are seriously influenced.
At present, more manual bagging or whitewashing agent smearing modes are adopted to prevent sunburn, and all other types of whitewashing agents also appear, so that the problems that time and labor are wasted, the adhesion of the glue whitewashing agent is strong, the washing is not easy and the like exist, the appearance of the fruit is influenced, and further the income is influenced.
