茶树扦插密度的生物学效应与经济效益

以中叶种碧云为材料,设计了15种扦插密度,对扦插密度的生物学效应和经济效益进行了研究。结果表明,扦插密度与成活苗数呈正相关,与成活率、出圃率呈负相关,对茶苗的质量影响不显著。在穗价和苗价分别为1.2元/500区和10.09元/株,行距为10 cm 时,以每666.7m~2扦插29.92万株的利润最高,扦插26.98万株的成本产值率最高,扦插12.59万株的插穗利润率最高,扦插25.54万株的综合效益最优。穗价和苗价对经济效益都有一定的影响,以苗价影响较大。在穗价和苗价发生变化后,最佳扦插密度也将改变。文中

Studies on the Biological Effect and Economic Benefit of Tea Cutting Density in Nursery

The author applied 15 cutting densities by using cv Biyun in order tostudy the biological effect and economic benefit of tea cutting density innursery.The results showed that the cutting density was positively relatedto the survival number of cutting nurselings,but negatively to the survivalpercentage and commercial percentage.It had no influence on the qualityof cutting nurselings.If the prices of cutting wood and cutting nurselingwere 1.2 Yuan/500g and 0.09 Yuan/cutting nurseling respectively,and therow distance was 10 cm,the optimum cutting densities of profit and outputvalue/cost and profit/500g cutting wood and total benefit would be 299200,269800,125900 and 255400 cuttings per 0.0667hm~2 respectively.Both the pricesof cutting wood and cutting nurseling can affect the economic benefit,howeverthe price of cutting nurseling will bring larger influence on the benefitthan the cutting wood price.The optimum cutting density should be flolowedwith the change of the prices of cutting wood and cutting nurseling.Thecorelation equations were described in the paper.
