在柑桔生产实践中,如何确定桔树的负担量,以达到连年高产、稳产、优质,这是一个十分重要的问题。 自1980年开始,笔者调查了黄岩县院桥压沙埠乡吕白洋村一片五年生山地温州蜜柑(枳砧)园的树体结构,探讨其适期投产及合理负担的树体形态指标。在调查中发现:柑桔树干周大小与树体生长量和结果量是相关的。即干周或其横断面面积越大,能负担的果量越多;而干周或其横断面面积越小,所能负担的果量亦越少。但它们的单位于横断面面积负果量却基本相同。 为了进一步研究柑桔主干横断面面积与产量之间相关性的密切程度,探索确定果树
In citrus production practice, how to determine the burden of orange trees in order to achieve high yield, stable yield and high quality in successive years is a very important issue. Since 1980, the author has investigated the tree structure of a five-year-old mountain Satsuma (Citrus aurantium) garden in Luobanyang village, Xupu-yang village, Xupuqiao, Huangyan County, and explored the morphological indexes of trees suitable for proper production and reasonable burdens. Found in the survey: citrus trunk circumference size and tree growth and the amount of results are related. That is, the larger the dry week or the cross-sectional area thereof, the more fruit it can afford; and the smaller the dry week or its cross-sectional area, the less fruit it can afford. However, their unit is basically the same in negative cross-sectional area. In order to further study the correlation between citrus trunk cross-sectional area and yield,
