火龙果套种草莓栽培模式初探

Preliminary Study on Cultivation Pattern of Pitaya-Strawberry Relay Cropping

【目的】提高土地的利用率,增加火龙果园的经济效益。【方法】引进甜查理、章姬、冬香、书香和燕香5个不同草莓品种,采用随机区组排列方法,进行火龙果套种草莓栽培模式试验,分析对比经济效益情况,筛选出适合火龙果园套种的草莓品种。【结果】终收期最早的是章姬,其次是冬香;结果期最长的是甜查理,为118d;其次是书香,为114d;燕香和章姬的结果期相似,均为112d;冬香的结果期最短,仅为105d。各品种的单果重、株产、单产差异较大,依次为甜查理、书香、燕香、冬香和章姬。不同草莓品种的生长状况和植株形态差异较大,从株高和冠幅来看,书香最高大,其次是冬香,甜查理的株高最低。套种草莓模式亩净产值较单种火龙果最少多4900元,亩净产值最多的是套种甜查理,达8822元,其次是书香,亩净产值达8650元。【结论】火龙果园套种草莓可取得较为可观的经济效益,套种品种可选择产量表现较高的草莓品种甜查理和书香,每667m^2可获净收益8600元以上。

[ Objective ] It aims to improve the utilization rate of land and increase the economic benefit of pitaya orchard. [ Method ] Fivedifferent strawberry Zhangji, Dongxiang, Shuxiang and Yanxiang; a trial carried out with randomgroup arrangement ; varieties are screened out by analyzing economic benefits. bydongxiang;Sweet Charlie has the longest fruiting varieties are introduced, including Sweet Charlie, of pitaya-strawberry relay cropping in the orchard is of strawberry suitable for relay cropping with pitaya [ Result ] The earliest harvest is Zhangji, followed period, which lasts 118d; the second is Shuxiang, 114d ; and the fruiting period of Yanxiang and Zhangji are similar, both 112d ; Dongxiang has the shortest fruiting period, only 105d. The single fruit weight, plant yield and yield of each variety are relativelydifferent,with Sweet Charlie, Shuxiang, Yanxiang, Dongxiang and Zhangji indescending order Thegrowth status and plant morphology ofdifferent strawberry varieties are also various-in terms of hei and crown width, Shuxiang is the highest and the largest, followed bydongxiang, and Sweet Charlie is lowest.The net output value per mu of relay cropping pattern is at least ￥4,900 more than that of pitaya alone, and the largest net output value per mugoes to Sweet Charlie, which is ￥ 8,822; followed by Shuxiang, ￥ 8,650. [ Conclusion ] Pitaya-strawberry relay cropping brings about substantial economic benefits;favorable varieties of strawberry should be Sweet Charlie and Shuxiang with relatively high yield, ensuring net income of over ￥ 8,600 per 667m2.
