四、植物生长分析根据许多试验结果,无论是植物的个别器官或整株植物的生长过程,都表现出“慢——快——慢”的基本规律,即开始时植物生长有一个迟滞期,此时生长缓慢;迟滞期以后,生长速度加快,直到达最大生长速度,称为对数生长期;在对数生长期之后,生长速度又减缓,最后达到稳定期,此时植物或器官进入成熟和衰老(也有人称为衰老期)。一般把生长的这三个时期总 4. Plant Growth Analysis According to many test results, the basic law of “slow-fast-slow” is displayed whether it is the growth process of an individual organ or whole plant of a plant, that is, there is a lag phase of plant growth at the beginning, At this time slow growth; after the lag phase, the growth rate to accelerate until it reaches the maximum growth rate, known as the logarithmic growth phase; in the logarithmic growth phase, the growth rate slowed down and finally reached a stable period, when plants or organs into the mature And aging (also known as aging). The general growth of these three periods
