Every year when the kiwi fruit is to be picked and harvested, it is also the key season for citrus sun-proof fruit, although the weather temperature is not as bad as in the early days, but the fruit sunburn is more likely to occur during this time. #Sannong Squad#
Citrus fruit sunburn in addition to the sun is related to the sun's poisonous, but also related to the growth and development of the fruit, which also shows that the early stage of such a high temperature, so fierce sun, sunburned fruit is not a lot, because the pulp of the citrus fruit at that time and the skin oil bubble growth rate is slower, the resistance to the high temperature of the sun is also stronger.
In addition to using foliar calcium fertilizer to enhance the resistance of the epidermis layer of the fruit, the prevention of citrus sun fruit mainly adopts the technical measures of white reflection of the fruit surface to prevent and control.
Most growers use several measures:
First, spray anti-sun protection agents on the surface of the fruit;
Second, sticker sunscreen;
The third is to cover the shade net for sun protection. #New Farmer Creation Contest#
In the past, there were stickers containing glue on the market, which were directly stained on the surface of the fruit, but the glue would have some problems in the later stages of the surface of citrus fruits, and it was not suitable for use on citrus varieties such as raking mandarin oranges and Ehime.
The fruit farmers of Pujiang local fruit growers have made some improvements to the stickers, using the method of rice soup and toilet paper to use on the fruit, and it plays a role in sun protection, and it will not harm the fruit, nor will it affect the growth of the fruit tree. Especially in areas with severe high temperatures, it is worth a try.
The sun protection effect of the citrus cover shade net is better, but the impact on the growth of fruit trees is greater, and the shade net needs to be removed in time after the high temperature to avoid affecting the growth of fruit trees.
In addition, there are also the use of citrus orchards in the sky and underground spray water cooling and sunscreen method, but the use of conditions are higher, one-time investment is also large, to the current citrus market situation, the use of the crowd is not much.
