Delay in the release from the sigmoid-type HCRF-S70 is due to its larger amount of water requirement to start the nutrient release as compared to the exponential type HCRF-E50.

与指数曲线形的HCRF - E50相比较，S曲线形的HCRF - S70养分释放推迟是由于养分开始释放时所需水分量较大。

To initiate the release nutrients, a certain amount of water needs to permeate into the film-coated controlled release fertilizer, HCRF-S70 needs more water to permeate than HCRF-E50.

为了养分的开始释放，需要一定量的水分透入包膜肥料内，HCRF - S70需要透入的水比HCRF - E50的多。
