不同管理措施对海南冬季辣椒生长及经济效益的影响

Effects of Different Management Systems on the Growth and Economic Benefits of Winter Pepper in Hainan

为探讨海南冬季辣椒高产施肥管理的适宜措施,以‘南方1号’辣椒为试验材料,研究稻草还田及其配施尿素和腐熟剂、移栽时间等综合管理措施对辣椒生长发育、产量及经济效益的影响。结果表明,不同处理对辣椒叶色、株高、茎粗、单果数、单果重、单株干重、总产量及辣椒经济收入均具有显著的影响,其中在稻草还田配施尿素和腐熟剂后30 d移栽辣椒的管理措施均表现最佳,与CK相比,净增收为3441元/hm^2。另外,采用稻草还田及其配施尿素和腐熟剂的条件下,辣椒总产和经济收入均随移栽时间的推迟而表现出增加的趋势。综上所述,海南冬季辣椒生产中,要考虑前茬水稻秸秆还田,并适当配施尿素和腐熟剂,同时还要考虑到适宜的移栽时间,以保证辣椒增产增效。

The effect of rice straw returning and combined with urea,decomposition agent and transplant time on the growth,yield and economic benefit of pepper was studied in order to analyzed the high yield fertilization management systems of winter pepper‘Nanfang No.1’in Hainan province.The results showed that the leaf color,plant height,stem diameter,number of single fruit,weight of single fruit,dry weight of single plant,total yield and economic income of pepper are significantly affected by different treatments.Meanwhile,the treatment of transplanting 30 d after straw returning combined with urea and decomposing agent is the best management measure,and the economic net income is 3441 yuan per ha.In addition,the total yield and economic income are increased with the delay of transplanting days.Therefore,it is necessary to consider returning of previous rice straw with applying urea and straw decomposing agent,as well as the appropriate transplanting time to guarantee yield and economic benefits for winter pepper production at Hainan Province.
