本文通过大田试验,总结出台农4号菠萝在不同种植密度和不同基肥水平综合作用下的生长和产量变化规律,看出种植密度的主要作用在于增加单位面积的结果数量,而基肥水平则有促进菠萝生长发育以提高的单果重的作用.提出福建南部采用亩植4400株,配合每造施用优质有机肥料2000公斤,可获得密植连造亩产2000-3000公斤的产量.为进一步推广台农4号菠萝提供了科学依据.
In this paper, field trials were conducted to summarize the changes of the growth and yield of pineapple under the combined effects of different planting densities and basal fertilizer levels. The main effects of planting densities were to increase the number of fruit per unit area and the basal fertilizer level Pineapple growth and development to improve the role of single fruit weight.Used 4400 acres planted in southern Fujian, with each application of high-quality organic fertilizer 2000 kg, dense planting can be obtained with a yield of 2000-3000 kilograms per mu .To further promote Taiwan agricultural 4 No. pineapple provides a scientific basis.
