Technical Field
The invention belongs to the technical field of plant protection, and particularly relates to a micro-film calcium fruit suntan protective agent and a preparation method and an application method thereof.
Technical Field
Sunscald is a physiological disease caused by solar radiant heat. In the high-temperature arid seasons of summer and autumn, the sunlight directly irradiates the naked branches and fruits of the fruit trees, and the burns can be caused when the surface temperature reaches more than 40 ℃. The bark damaged by sunburn falls off or cracks when it is severe. The surface of the fruit is exposed to sunburn, which turns white first and then browns. When the weather is extremely dry and continuously high temperature, the relative humidity of air is below 50 percent, the underground water supply is insufficient, and the transpiration is weakened, the direct strong light can also cause the leaves of fruit trees such as apples, pears and the like to burn.
In order to prevent sunscald, fruit growers mostly adopt ways of pasting paper, whitening fruits, pulling a sunshade net and the like, but the prevention effect is not very effective, sunscald cannot be completely prevented, and the eating value of fruits is influenced to a certain extent. In the prior patent, CN 109892330A discloses a crop sunscald control agent and an application thereof, the crop sunscald control agent takes sodium alginate oligosaccharide as an active component, the method can reduce sunscald and labor cost for sunscald control, but the agent needs to be applied every 7-10 days and cannot rapidly and effectively reduce sunscald. The invention researches a micro-film calcium protective agent which can form a layer of protective film on the surface of fruits after being sprayed, block and reduce ultraviolet rays in sunlight, reduce diseases caused by high temperature and sunburn, and increase crop nutrition.
