冬季补光对大棚火龙果开花结果的影响

Effect of Supplemental Lighting on Blossom and Fruiting of Pitaya in the Shed in Winter

以大棚内红肉系火龙果‘短芯’为试材,通过冬季夜间补光措施来诱导火龙果开花结果,研究其生长开花结果表现及花果生长期状况,探讨冬季补光对大棚火龙果开花结果的效应影响,结果显示,冬季夜间补光后,大棚‘短芯’火龙果补光处理植株于1月中旬即可成花,比对照提前3个批次开花结果,补光处理可有效地促使火龙果植株抽蕾成花。补光处理植株1,2,3,4批次花果生长期依次变短,果实单果质量及大小依次变小,差异显著,可为火龙果花期调控技术提供参考。

Taking the red pulp pitaya‘Duanxin’in the shed as the test material by applying supplement light measures to induce the flowering and fruiting of the pitaya in winter,the growth and development of pitaya flower and fruit were studied,and the effect after the implementation of supplementation lighting were explored.The results showed that‘Duanxin’pitaya could be flowered in mid-January after applying supplement light measures in winter.It could accelerate blossoming and fruiting for three batches.The supplemental lighting can promote flower buds of pitaya plants in the shed in winter effectively.The growth period of the first,second,third and fourth batches of flowers and fruits were shortened in turn,and the weight and size of Single fruit become smaller in turn,which can provide effective technical way to flowering regulation of pitaya.
