Method for preventing virus damage of applies planted in south

Abstract

The invention discloses a method for preventing virus damage of applies planted in the south. The method comprises the steps: mixing 10 parts of polypeptide mixed solution, 10 parts of monopotassium phosphate, 5 parts of urea and 1500 parts of water to prepare a conditioning solution in a plum rain season, and uniformly spraying the conditioning solution on two leaf surfaces of apple trees once every other 14-16 days, wherein the polypeptide mixed solution is prepared by mixing 100 parts of table vinegar, 4 parts of phethalanilic acid, 100 parts of amino acid and 1000 parts of water.

Description

technical field [0001] The invention relates to an apple planting method, in particular to a virus prevention method for southern apples. Background technique [0002] Apples have been grown in the north since ancient times, and it is extremely rare to grow apples in the south. There are many restrictive factors in planting apples in the south, among which multi-virus damage caused by climate is an important factor. [0003] The temperature and humidity in the south are higher than those in the north, and the sunshine time in the south is shorter than that in the north. Especially in the rainy season, there are many rainy days and the sunshine is seriously insufficient. Moreover, the roots of apples in the south often accumulate water because of the rain in the south. High temperature, high humidity and long-term overcast and rainy days are conducive to the spread of southern apple viral diseases, causing serious leaf and fruit drop, premature aging and even dead plants in ...
