摘要
为研究遵辣9号的较佳种植密度,采取随机区组设计,开展不同种植密度对遵辣9号产量与效益的影响研究。结果表明:随着种植密度的不断加大,遵辣9号产量成曲线变化趋势,峰值出现在2500株/667 m^(2),此时鲜椒产量达1471.85 kg/667 m^(2),比CK 2000株/667 m^(2)高5.7%,比处理3000株/667 m^(2)高9.5%,比处理3500株/667 m^(2)高13.17%,比处理4000株/667 m^(2)高34.76%,比处理4500株/667 m^(2)高44.98%。2500株/667 m^(2)时,经济效益达到最高,为5298元/667 m^(2),减去投入成本后,纯收入最高为2208元/667 m^(2),纯收入产出投入比最高为1∶0.715。结果表明,2500株/667 m^(2)是遵辣9号较佳的群体结构和种植密度。
In order to get the optimal planting density of Zunla 9,the effects of different planting densities on the yield and economic benefits of Zunla 9 were studied using a randomized block design.The results showed that the best planting density was 2500 plants/667 m^(2) with the yield of 1471.85 kg/667 m^(2),which was 5.7%,9.5%,13.17%,34.76%,and 44.98%higher than the densities of 2000 plants/667 m^(2),3000 plants/667 m^(2),3500 plants/667 m^(2),4000 plants/667 m^(2),4500 plants/667 m^(2),respectively.The economic benefit reached up to 5298 Yuan/667 m^(2) at the density of 2500 plants/667 m^(2),which was the highest.The net income was 2208 Yuan/667 m^(2) and the ratio of output and input was 1∶0.715 under the best planting density.As a result,the choice of appropriate planting density can improve the economic benefit of planting Zunla 9.
