摘要:以‘戴多星’水果型黄瓜为试验材料,采用椰糠无土栽培方法,行距为150cm,株距分别为25cm、33.3cm、50cm(1m长的栽培袋分别定植4株、3株和2株),以研究光伏温室下不同栽培密度对黄瓜生理代谢、品质及产量的影响。结果表明,随着种植密度的减小,黄瓜生长指标的隶属函数值、净光合速率和气孔导度、单株总产量都显著增加,果实品质的灰色关联度为每袋3株的种植密度较优,而种植密度对叶绿素a、叶绿素b、胞间CO2浓度和蒸腾速率的影响不显著。说明1米长栽培袋每袋2株的种植密度较适用于光伏温室黄瓜的栽培生产。29796 毕业论文关键词:光伏温室;黄瓜;种植密度;品质

Abstract:With the 'deltastar' fruit cucumber as experimental material, using coir soilless cultivation method of row spacing is 150cm, spacing are respectively 25cm, 33.3cm, 50cm (1m long cultivation bags were planted in 4 strains, 3 strains and 2 strains), with different planting density on physiological metabolism of Cucumber under the influence the quality of photovoltaic greenhouse.and yield.The results show that with the decrease of planting density, the growth indexes of cucumber membership function value, net photosynthetic rate and stomatal conductance, yield per plant increased significantly, grey correlation degree of fruit quality is the best planting density of 3 per bag line, and planting density on chlorophyll a, chlorophyll b, effect of intercellular CO2 the concentration and transpiration rate was not significant.The results showed that the planting density of 1 rows of 2 bags per bag was more suitable for the cultivation of Cucumber in Solar Greenhouse
