生长受阻的英文
例句与用法
- In most plants, the terminal growth is affected first .
大多数植物，先是顶端生长受阻。 - In view of it , when the day grain made up with existing fodder raw materials can t meet the nutrition balanced , we can add fish meal to guarantee day grain nutrient balance , make the growth obstruction be avoided or reduced to minimum extent because of the lack of nutrient
基于此点，当用已有的饲料原料不能配合出营养平衡的日粮，添加鱼粉即可确保日粮养分的平衡，使由于养分缺乏造成的生长受阻或限制得以避免或降低到最小程度。 - The am fungus could obtain adequate carbon resources for itself , thus ensuring normal growth and metabolic activit y owing to the efflux of carbohydrate from the plasma membrane of the host root cortical cells to the interface of the symbiosis . thirdly , the structure and composition of the root cortex cellular plasma membrane kept good integrity and the leakage of carbohydrate maintained at low level when the plant obtained enough p and metabolizes normally . although enough carbohydrate was synthesized by plant , the am fungi could not obtain enough energy , resulting in inhibition of growth of the extraradical hyphae and decreased metabolic activity of the am fungi
由此，我们认为植物磷营养状况调控菌根真菌生长和代谢活性的机制是：当植物处于严重缺磷胁迫时，不能合成足够的碳水化合物供给自身生长的需要，也不能向真菌提供额外的碳水化合物，因而菌根真菌生长受阻，代谢活性较低；当植物中度缺磷时，根皮层细胞质膜的组成和结构不完整，通透性大，碳水化合物通过质膜向外的渗漏量大，菌根真菌因而获得充足的碳源，保证真菌正常的生长和旺盛的代谢；当植物获得足够的磷而使体内磷营养代谢正常时，其细胞质膜组成和结构完整，碳水化合物的渗漏量保持在较低的水平，尽管此时植物合成了足够的碳水化合物，但菌根真菌仍不能获得足够的能量，导致真菌生长受阻和代谢活性降低。 - Because there are a great quantity ' s heterotrophic bacteria in the breeding pool , which will have the repulsion action to the insufficient quantity ' s nitrifier and prevent the nitrification , the situation will bring the accumulating of nitrite which is the middle substance of nitrification in water , the long term accumulated nitrite can debase fish and shrimp ' s disease - resistant and decrease the growth and even die
由于养殖池中存在大量的异养菌，受到异养性细菌排斥，本身无足够数量的硝化菌，硝化作用往往受阻，结果就会引起硝化作用的中间产物亚硝酸盐在水体内的累积、亚硝酸盐长期蓄积会使鱼虾等抗病力降低、生长受阻、严重者中毒死亡。
