光照强度对金桔果皮品质的影响

Effect of Light Intensity on the Quality of Kumquat Peel

为研究光照强度对金桔果皮品质的影响,利用长安镇农田小气候站2021年8—9月逐日的光照强度、空气温度等气象资料,结合在同株脆蜜金桔上分别在东、南、西面观测金桔果皮的日灼情况。结果表明:日灼果的发生只有光照强度是不明显的,在光照强度的同时必须有高温天气。因此,光照强度只是日灼发生的必要条件之一,日灼发生必须同时存在高温和光照强度,得出融安县脆蜜金桔发生日灼的临界条件为:在融安县气候条件下,连续10 d内的光照强度均值在50 000 1x以上,平均气温在33℃以上,日最高光照强度在82 000 1x以上,日最高气温达35℃以上。

To find out the effect of light intensity on the quality of kumquat peel.Using the daily meteorological data such as light intensity and air temperature from August to September 2021 at the farmland microclimate station in Chang’an Town, and combining with the crisp kumquat of the same plant, select one branch in the east,south and west respectively to observe the sunburn of kumquat peel. The results showed that the occurrence of sunburn fruit was not obvious only in light intensity, but also in high temperature weather. Therefore, light intensity was only one of the necessary conditions for the occurrence of sunburn, which must be accompanied by high temperature and light intensity. Therefore, the critical conditions for the occurrence of sunburn of crisp honeyed kumquat in Rong’an County are as follows:under the climate conditions of Rong’an County, the average light intensity is more than 50 000 lx, the average temperature is more than 33℃, the maximum daily light intensity was more than 82 000 1x, and the maximum daily temperature was more than 35℃.
