外温动物与植物的发育不仅需要一定的时间,还需要时间和温度的结合(称生理

The development of ectothermal animals and plants not only requires a certain amount of time, but also requires a combination of time and temperature (called physiological time), that is, a certain amount of total heat, called total accumulated temperature or effective accumulated temperature, can complete a certain stage of development. This rule The description of is the effective accumulated temperature rule: K=N (TC), K: effective accumulated temperature, N: developmental period, T: average temperature of the environment during development. C The developmental threshold temperature of the organism.

The development of external temperature animals and plants requires not only a certain time, but also the combination of time and temperature (called physiological time), that is, a certain total heat, called total accumulated temperature or effective accumulated temperature, can complete a certain stage of development The description of this law is the law of effective accumulated temperature: k = n (T-C), K: effective accumulated temperature, N: development period, t: average ambient temperature during development C development threshold temperature of the organism.

The development of ectotherms and plants not only needs a certain amount of time, but also needs the combination of time and temperature (called physiological time), that is, it needs a certain amount of total heat, called total accumulated temperature or effective accumulated temperature, in order to complete the development of a certain stage. The description of this rule is the rule of effective accumulated temperature: k = n (t-c), k: effective accumulated temperature, n: development duration, t: environmental average temperature during development. C should be
