粘红酵母菌肥对蓖麻生长性状及其种子含油量的影响

摘要

In order to study the effect of Rhodotorula glutinis fertilizer on the quantitative characters and seed oil content in seed,three treatments such as Rhodotorula glutinis microbial fertilizer,chemical fertilizer of compound elements and control were carried out both in pot and field experiments. Plant height and diameter during the growth period,seed size and its water content in fresh seed and oil content in dry seed after harvested were detected. The results demonstrated that Rhodotorula glutinis fertilizer promoted the Ricinus communis sprout growth and the seed oil content,and inhibited the mature plant,seed size and its fresh weight. The seed oil content of Ricinus communis treating with Rhodotorula glutinis microbial fertilizer was 40.33%,significantly higher than that in control treatment.%为了解粘红酵母菌肥的施用对蓖麻植株生长、种子性状及其含油量的影响，分别测定了菌肥施用组、化肥施用组和空白对照组的蓖麻植株株高和茎粗、收获期种子籽粒大小、鲜重、鲜籽粒含水量和干籽粒含油量。结果表明：粘红酵母菌肥对盆栽蓖麻苗期的株高增长有不显著的促进作用，而化肥则表现出显著的抑制作用；粘红酵母菌肥对田间蓖麻植株生长中后期的株高和茎粗均有显著抑制作用；粘红酵母菌肥对蓖麻种子大小和鲜重增加也有显著抑制作用，而对种子鲜籽粒含水量和干籽粒含油量的积累有显著促进作用；菌肥施用组所得蓖麻种子含油量可达40.33%，显著高于对照。
