摘要

许多研究报道,褐藻是支持农田和园艺植物生长发育的肥料和生物刺激素的主要来源。本文报道了施用不同浓度的褐藻(sargasumpolysistum)对水稻生长和产量的影响。自水稻种植后21天起。分别用0、5、10、15、20%的皂荚提取物对植株进行喷施。这些植物在营养生长期间每周喷洒一次。结果表明,在最大浓度为10%之前,聚马尾草对水稻植株的生长有促进作用。然而,当添加量超过10%时,生长下降,在产量参数(如青霉数和种子重)中也表现出类似的现象。

Growth and yield of rice plants sprayed with Sargassum polycystum extracted with different of concentration
Many reserches reported that brown algae is main source of by fertilizer and biostimulant for supporting growth and development of agriculturaland horticultural plants. This article reports growth and yield of rice plant sprayed with different concentration of Sargassumpolysistum, one of brown algae species. Since the age of rice plant was 21 days after planting. The plants were sprayed with 0, 5, 10,15, 20% of Sargassumpolysistum extract. The plants were sprayed one a week during vegetative growth. The results show that concentration of Sargassumpolysistumincreased the growth of rice plants until maximum concentration 10%. However, when this extract applied in more than 10%, the growth was decreased similar phenomena was also demostrated in yield parameters, such as penicle number and seed weights.
