不同补光时段对日光温室草莓生长的影响

Effects of Different Supplemental Light Periods on Strawberry Growth in Greenhouse

为了解决设施草莓栽培在冬季低温寡照引起的品质和产量下降的问题,选用红蓝相间的LED灯对日光温室草莓补光问题进行了试验,选用4个时间段补光,以不补光为对照,测定4个补光处理对2个草莓品种的农艺性状、草莓产量、品质、抗病虫害的影响。结果表明,2个草莓品种选用处理2(4:00—8:00补光),草莓植株生长适用,花枝数、花蕾数显著增加,草莓品质及产量明显提高,抗病虫性优于其他处理。

To solve the problem of quality and yield decline caused by low temperature and low illumination of strawberry cultivation in greenhouse in winter,red and blue LED lamps were used to supplement the light of strawberry in solar greenhouse.Four methods of providing supplemental light was applied and the effect of each was compared with that of strawberries without any supplemental light.The agronomic characteristics,yield,quality and resistance to pests and diseases of two varieties of strawberries growing under the circumstance of utilizing four different light-supplement methods was measured.The result showed that when treatment 2(4:00-8:00 supplemental light),was applied to the two types of strawberries,the overall effect was considerably better than that of others.Specifically,the growth of plants was appropriate,the number of blossom branches and buds had remarkable increase and the fruit quality and yield were improved significantly.Additionally,the resistance of diseases and pests was stronger than those using other methods.
