Effects of film partition on yield and fruit quality of mountain bayberry in facility cultivation

Abstract

Abstract:

Taking the Biqi variety of bayberry in mountainous facilities as the test object，a 0.66 hm² integral multi-span arched greenhouse was vertically divided by plastic film into three（upper，middle and lower）or two（upper and lower）individual greenhouses，thereby changing the internal microclimate and achieving the goals of increasing yield，improving quality，and enhancing benefits. The results shows that the film partition is conducive to increasing the temperature and relative humidity of individual greenhouses. Specifically，compared with the non-partitioned treatment（CK），the temperature and humidity in the upper individual greenhouse can be raised by 1.2-7.8 ℃ and 0.8-12.4 percentage points，respectively. The maturity period is advanced by 5 to 8 days，and the harvest and supply period is extended by at least 1 to 2 days. Compared with CK，the single fruit weight of the film-partitioned treatment significantly（p<0.05）increased by 14.26%-17.63%，and the soluble solid content significantly increased by 1.26-2.35 percentage points. For the film-partitioned treatments，intrinsic qualities such as total sugar，flavonoids，and vitamin C contents were significantly improved. In the treatment divided into three individual greenhouses，the contents of these three components were 119.38 mg·g^-1，0.95 mg·g^-1 and 295.37 μg·g^-1，respectively，which were 31.17%，26.67% and 27.76% higher than those in CK. Total acid decreased by 21.09%-22.61%. There was no significant difference in average yield between the film-partitioned treatments and CK，while the commercial fruit rate and premium fruit rate were 85.81%-90.25% and 66.55%-72.34%，respectively，which were significantly higher than those of CK by 10.14-14.58 percentage points and 12.86-18.65 percentage points. The output value of the film partition treatments was 777 800-791 900 yuan·hm^-2，which was 43.11%-45.70% significantly higher than that of CK. The film partition of facilities for mountain bayberry production is simple，resulting in stable yield，excellent quality，and high benefits，thereby making it suitable for promotion in mountainous areas.
