设施大棚铺设银色反光膜栽培杨梅试验研究

Experimental Study on Bayberry Plants in the Greenhouse with the Soil Covered with the Silvery Plastic Film

在设施大棚杨梅园铺设银色反光膜,试验研究大棚铺设反光膜对‘临海早大梅’物候期、果实品质及效益的影响。以大树移植3年的11年生‘临海早大梅’为试材,2013年1月11日对其进行大棚覆盖,并于2月13日大棚内铺设银色反光膜,以不盖为对照,观察记载棚内外温湿度、杨梅物候期的变化,测定果实单果质量、可溶性固形物含量和每公顷产量。大棚杨梅园铺设反光膜可显著增加棚内的温度和相对湿度,使杨梅的物候期显著提早,开花期提早16天,果实成熟期提早21天,果实单果质量增加10%,可溶性固形物含量增加2.1个百分点,每公顷产量提高45.6%,净增产值1265610元。设施大棚铺设反光膜栽培杨梅,可以显著提早成熟期,显著提高单果质量和可溶性固形物含量。

It was studied that the effect of the greenhouse with silvery plastic film on the soil on the phenology, fruit quality and economic benefit of ＇ Linhai zao da mei＇. The eleven-year-old trees were tested after the transplant for 3 years. The greenhouse and the soil were covered on January 11, 2013 and February 13, 2013 respectively. The temperature and humidity inside and outside of the greenhouse were detected real time. The phenology of the bayberry tree was observed. The average quality of single bayberry fruit, the content of soluble solids and the yield per hectare of ＇Linhai zao da mei＇ were tested. Compared outside the greenhouse, the temperature and humidity were significantly increased inside, and the phenology significant earlier, fowering period with 16 days, fruit ripe time with 21 days. The average fruit quality were increased by 10%, and the content of soluble solids increased by 2.1 percentage points, and the yield per hectare increased by 45.6%, and the net economic value increased with 1265610 yuan. The matureness of bayberry fruit were earlier, and the average single fruit quality and the content of soluble solids were increased significantly in the greenhouse withthe soil covered with plastic film.
