光碳核肥在大棚栽培草莓上的应用

Application of CO2 Capture Agent on Strawberry in Greenhouse Cultivation

为促进光碳核肥的推广应用,以“爱莎”草莓为材料,设T1(施商品有机肥4000 kg·667 m-2,氮磷钾复合肥30 kg·667 m-2)、T2(草莓生长过程中喷施6次光碳核肥)、T3(施商品有机肥3000 kg·667 m-2,草莓生长过程中喷施50%T2用量的光碳核肥)、CK(不施肥,喷施清水),调查不同处理下草莓株高、茎粗、叶面积、叶片SPAD、光合作用及产量情况。结果表明:在T3处理条件下,草莓株高茎粗均高于其他处理,其次为T2处理。T3和T2处理的净光合速率均显著高于对照。T3处理的气孔导度最大。T2处理的胞间CO2浓度和气孔蒸腾速率最大。T3处理的叶面积和SPAD值最高,产量也最高。可见光碳核肥和有机肥配施效果最好,可显著提高植株的株高、茎粗和产量等。

In order to promote the application of CO2 capture agent,“Esha”strawberry was used as the material,T1(4000 kg·667 m-2 of commercial organic fertilizer,and 30 kg·667 m-2 of NPK compound fertilizer),T2(six times of CO2 capture agent spraying during strawberry growth),T3(3000 kg·667 m-2 commercial organic fertilizer spraying 50%of T2 CO2 capture agent during strawberry growth)and CK(not fertilizer,spraying water).The plant height,stem diameter,leaf area,leaf PSAD,photosynthesis and yield of strawberry under treatments were investigated.The results showed that,under the condition of T3,strawberry plant height and stem diameter were all higher than other treatments,followed by T2.The net photosynthetic rate of T3 and T2 treatment was significantly higher than that of the control group.Stomatal conductance was the highest in T3 treatment.T2 treatment had the highest intercellular CO2 concentration and stomatal transpiration rate.T3 treatments had the highest leaf area and SPAD values.T3 treatment had the highest yield.The combination of CO2 capture agent and organic fertilizer had the best effect,which could significantly improve plant height,stem diameter and yield.
