The arrangement of the lamp tubes under the ears is schematically shown in figure 1,
3. one week before initial stage to harvest stage
The light supplement is carried out one week before the initial ripening period of the 'Jingxiangyu' fruit (Brix is approximately equal to 4) until the fruit is ripe (the light supplement time is about 50 days, and the variety takes about 88 days from flowering to fruit ripening). Supplementing light for 6 hours every day, wherein the setting time is 03% before sunlight is emitted into the greenhouse every day: 00-06: 00 and 20 after sunset: 00-23: 00. the fruit grains at the upper position of each cluster of fruit ears receive the light intensity of about 45 mu mol.m-2·s-1The light intensity at the central position is about 55. mu. mol. m-2·s-1The light intensity at the lowermost part (i.e., the position closest to the lamp tube) is about 70. mu. mol. m-2·s-1As shown in fig. 3.
After the blue light is supplemented to the fruit clusters, the content of soluble solids in the fruits is obviously improved: the TSS of the fruit subjected to light supplement is 14.3 +/-0.5%, and the TSS of the fruit not subjected to light supplement is 12.2 +/-0.3%.
The blue light supplement treatment is carried out on the fruit clusters, so that the content of total volatile aroma substances in the fruits is remarkably improved: volatile aroma substance content per kilogram of fresh weight of fruit: 300 +/-15.0 mu g of light is not supplemented, and 500 +/-25.0 mu g of light is supplemented;
as shown in fig. 4 and 5, the content of volatile terpene compounds, which are aroma-generating substances with rose aroma in fruits in the mature period, was increased by about 8 times after the light supplement for 40 days, and the content of volatile terpene compounds per kg fresh weight of fruits was: the number of fruits not supplemented with light is 15.5 +/-1.0 mu g, and the number of fruits supplemented with light is 142 +/-5.0 mu g; the content of the volatile terpene compound linalool with the highest content is increased by nearly 8 times after light supplement: the light supplement amount in the fruits is 10.3 +/-0.7 mu g, and the light supplement amount in the fruits is 92 +/-7.0 mu g. In the mature period after the light supplement of 50 days, the content of volatile terpene compounds and linalool in the light supplemented fruits is still 2.89 times of that in the fruits without light supplement (the content of volatile terpene compounds in each kilogram of fresh fruits is 94.21 mu g in the fruits without light supplement and 272.99 mu g in the fruits with light supplement; the content of volatile linalool substances is 64.8 mu g in the fruits without light supplement and 187.49 mu g in the fruits after light supplement).
The analysis shows that the method can obviously improve the quality of the Jingxiangyu fruit in the mature period: can remarkably improve the content of soluble solid in the 'Jingxiangyu' fruit in the mature period and remarkably improve the content of total volatile aroma substances in the fruit, in particular volatile terpene compounds (the highest content is linalool).
