Embodiment 1

[0010] A method for preventing sunburn of citrus, comprising the following steps: (1) Appropriately spraying calcium, potassium, magnesium and other elements before and after flowering and young fruit stage from March to June to increase resistance and reduce sun-drying, cracking and falling of fruit; 2) Put some late summer shoots in early July, which can expand the canopy and save labor without wiping the buds, and can also shade the sun to reduce sunburn; (3) From July to September, use light calcium carbonate, pure acrylate latex, Mix it with water, and apply white to the fruit once for sun protection, so as to prevent severe weather such as heavy rain and eliminate the white application. Preferably, light calcium carbonate, pure acrylic latex, and water are in a weight ratio of 10:5:1; (4) in In the high-temperature and dry August-September, the weather is sunny for 7 consecutive days and the soil is dry, so water it in time to prevent cracking, especially for tribute oran...

[0012] A method for preventing sunburn of citrus, comprising the following steps: (1) Appropriately spraying calcium, potassium, magnesium and other elements before and after flowering and young fruit stage from March to June to increase resistance and reduce sun-drying, cracking and falling of fruit; 2) Put some late summer shoots in early July, which can expand the canopy and save labor without wiping the buds, and can also shade the sun to reduce sunburn; (3) From July to September, use light calcium carbonate, pure acrylate latex, Mix it with water, and apply white to the fruit for 2 times to prevent sunscreen, so as to prevent bad weather such as heavy rain and eliminate the white application. Preferably, light calcium carbonate, pure acrylate latex, and water weight ratio are 11: 6: 1; (4) in In August-September, when the weather is hot and dry, the soil is dry for 10 consecutive days, and the soil should be watered in time to prevent cracking, especially for tribute oran...

Abstract

The invention discloses a method for preventing oranges from being sunburned. The method comprises the following steps of 1, appropriately spraying calcium, potassium, magnesium and the like around the flowering period and in the young fruit period from March to June; 2, releasing some late summer shoots in early July; 3, mixing light calcium carbonate, pure acrylic ester latex and water to whitenthe fruits once or twice in July to September; 4, timely spraying water when it is continuously sunny and soil is dry for 7-10 days in August to September when the temperature is high and it is dry;5, using colored paper or paper pieces to be attached to the surfaces of the fruits; 6, appropriately cultivating unripe grass in an orchard. The method can lower the temperature on the surfaces of the oranges, the occurrence of the situation that the oranges are sunburned is reduced, and the cracked fruits are reduced.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a method for preventing citrus from sunburn. Background technique [0002] Entering September, the temperature in most of the citrus areas in the south is still high, but the rainfall has decreased. Under the attack of high temperature and drought, citrus in the fruit expansion period is easy to sunburn, resulting in a decrease in the commodity rate. [0003] Sunburn is a kind of high temperature heat damage to citrus. If the temperature rises above 35 degrees in a short period of time, the temperature of fruit trees and tree bodies exposed to direct sunlight can reach above 45 degrees. And other varieties are very easy to be burned. In the early stage of damage, the fruit showed that the larger oil bag ruptured, and the pericarp around the oil bag turned green and showed light yellow spots, and then expanded into flakes. As the burn increases, the necrotic oil bag turns black, and ...
