Abstract

Fertilizers are essential for both crops and weeds, yet the combined effects of longevity and placement have not been studied extensively. Thus, a greenhouse study was conducted to test the effects of fertilizer longevity and placement on pentas (Pentas lanceolata) and Pennsylvania bittercress (Cardamine pensylvanica) growth. Five fertilizer longevity treatments [3-4 month (M), 5-6 M, 8-9 M, 12-14 M] were applied via top-dressing, sub-dressing and incorporating to the substrate. Plant and weed growth were recorded as well as nutrient leaching. The results showed neither fertilizer longevity nor placement had significant impact on pentas growth, yet sub-dressing fertilizer treatments produced the largest bittercress leaf area and shoot dry weight. Moreover, fertilizer longevity and placement both impact nutrient leaching. Overall, in this study, fertilizer placement exerted a greater influence on weed growth than fertilizer longevity.

肥料施用年限及对容器内苦菜生长及防治效果的影响

肥料对作物和杂草都是必不可少的，但寿命和施肥的综合影响尚未得到广泛研究。因此，进行了一项温室研究，以测试肥料寿命和放置对五角草（pentas lanceolata）和宾夕法尼亚苦菜（Cardamine pensylvanica）生长的影响。通过追肥、次追肥和与基质结合的方式施用5种肥料长寿处理[3-4个月、5-6个月、8-9个月、12-14个月]。记录了植物和杂草的生长情况以及养分的淋失。结果表明，施肥年限和施肥量对苦菜生长均无显著影响，但补肥处理对苦菜叶面积和茎干重的影响最大。此外，肥料的使用寿命和放置都影响养分的淋失。总体而言，本研究中，施肥对杂草生长的影响大于施肥寿命。

期刊介绍： Scientia Horticulturae is an international journal publishing research related to horticultural crops. Articles in the journal deal with open or protected production of vegetables, fruits, edible fungi and ornamentals under temperate, subtropical and tropical conditions. Papers in related areas (biochemistry, micropropagation, soil science, plant breeding, plant physiology, phytopathology, etc.) are considered, if they contain information of direct significance to horticulture. Papers on the technical aspects of horticulture (engineering, crop processing, storage, transport etc.) are accepted for publication only if they relate directly to the living product. In the case of plantation crops, those yielding a product that may be used fresh (e.g. tropical vegetables, citrus, bananas, and other fruits) will be considered, while those papers describing the processing of the product (e.g. rubber, tobacco, and quinine) will not. The scope of the journal includes all horticultural crops but does not include speciality crops such as, medicinal crops or forestry crops, such as bamboo. Basic molecular studies without any direct application in horticulture will not be considered for this journal.
