摘要

摘要本研究旨在评价减小不同果枝数的“Roxo de Valinhos”无花果(Ficus carica)树间距对绿无花果产量的影响。无花果树有两个或四个结果枝,分布在四个地块上,行间距为2.5 m,行间距为3 m(0.50, 0.75和1.00 m),密度为每公顷8000株,5,333株和4,000株。实验分2020/2021和2021/2022两个周期进行。每周收获两次青果,量化每次收获的果实总数和每株总收获重量。计算每个评价周期的平均单株产量和估计产量。减少无花果树之间的间距可以增加产量。0.50 m的间距降低单株产量,但增产73%。有两根或四根结果枝的树在绿无花果的产量上没有差别。

Decreased spacing with different numbers of branches to enhance green fig production
Abstract The objective of this work was to evaluate the effect of decreased spacing between 'Roxo de Valinhos' fig (Ficus carica) trees with different numbers of fruiting branches on green fig production. Fig trees, with two or four fruiting branches, were distributed in four blocks, at a standard spacing of 2.5 m between rows, three spacing between plants in a row (0.50, 0.75, and 1.00 m), and densities of 8,000, 5,333, and 4,000 plants per hectare. The experiment was conducted during two cycles (2020/2021 and 2021/2022). Green fruits were harvested twice a week, and the total number of fruits per harvest and the total harvest weight per plant were quantified. The average production per plant and the estimated yield were calculated for each evaluation cycle. Decreasing the spacing between fig trees increases their yield. The spacing of 0.50 m decreases production per plant, but increases yield in 73%. There is no difference in the production of green figs between trees with two or four fruiting branches.
