含油污泥对三种作物出芽率和幼苗生长的影响

论文利用光照培养箱栽培实验分别研究了不同浓度含油污泥对小麦、绿豆和黄豆的出芽和幼苗期生长的影响,结果表明,高含油量的污泥抑制作物的出芽,而对绿豆影响较小,比对照样本低5%,中低浓度的含油污泥对绿豆和出芽有一定的促进作用,对黄豆的抑制作用最大,高浓度时所有黄豆幼苗死亡;低浓度的含油污泥对绿豆、小麦幼苗生长具有促进作用,含油污泥浓度高时,对三者都有不同程度的抑制作用,浓度越高,抑制作用越强;含油污泥对黄豆出芽率和幼苗生长率影响最明显,将直接影响黄豆的产量.

The Influence of Oily Sludgy on the Budding Percentage and Seedling Growth Rate of Three Crops

The influence on budding and growth of wheat, mung bean and soya bean in the seedling stage by the oil of different concentrations in the oily sludge was studied by the planting experiment in illumination box. The results indicate that the oil of high concentration in oily sludge restricts the crop to bud. The effect on the budding of mung bean is smaller, which is 5 % less than that of the comparison sample. While the oil of middle and low concentration in the oily sludg can promote the mung bean buding, and restrict the budding of soya bean mostly. The oily sludge of low oil concentration promotes the growth of the mung bean and wheat seedling. Restriction of different levels against the growth of three seedlings is represented by the oily sludge of high oil concentration. The higher the oil concentration is, the stronger the restriction is. The influence of oily sludge on the budding percentage and seedling growth rate of soya bean is most obvious, which can affect the output of the soya bean directly.
