用小粒种咖啡栽培品种SL28,以5种种植密度,分灌溉与不灌溉处理,对每条第一分枝的总节数、结果节数、每节结果数和每条第一分枝的结果数等产量组分作比较。在树冠的上、中、下三层测定这些产量组分。从树冠的上层至下层,每节结果数和每条第一分枝结果数逐渐减少。灌溉导致树冠中、下层的结果节数、每节结果数和每条第一分枝的结果数减少。每节结果数、每条第一分枝的结果数和种植密度呈负线性相关。讨论了灌溉和种植密度对产量组分的影响。结论是灌溉和密植加强了植株的营养生长,从而减少了树冠的透光度。这导致产量参数减少。
With the small-grain coffee cultivar SL28, the total number of nodes, the number of results, the number of results per section and the result of each first branch were calculated for each first branch with five planting densities, irrigated and not irrigated Number of other production components for comparison. The yield components were measured at the upper, middle and lower levels of the canopy. From the top to the bottom of the canopy, the number of results for each section and the number of results for each first branch gradually decrease. Irrigation led to lower and middle canopy results section number, the number of results for each section and the number of results for each first branch decreased. The number of results for each section, the number of results for each first branch, and the planting density were negatively correlated. The effects of irrigation and planting density on yield components were discussed. The conclusion is that irrigation and close planting enhance the vegetative growth of the plant, thereby reducing the light transmittance of the canopy. This leads to a decrease in yield parameters.
