Morphological characteristics of eucalyptus
Evergreen plants have periodic shedding of old leaves within a year. Most species are tall trees, a few are small trees, and few are shrubby. The shape of the crown is steeple, multi-branch, weeping branch and so on. Leaves simple, entire, leathery, sometimes covered with a thin waxy layer. Leaves can be divided into three types: young leaves, middle leaves and mature leaves. Most of the young leaves are opposite, smaller, heart-shaped or broadly lanceolate.

Early and delayed High-yield cultivation techniques of volvariella volvacea
The straw mushroom with poor ventilation is a high-temperature aerobic fungus, which needs enough oxygen in the process of growth and development. In the process of cultivation, in order to improve the stack temperature, sometimes the film covering time is too long, so that too much carbon dioxide in the stack leads to hypoxia, and mushrooms wilt because of poor ventilation, poor exhaust and difficult to grow up normally. Sow seeds.

Like light, good wet, drought-resistant, heat-resistant. Afraid of the cold, very sensitive to low temperatures. Some species originated in the tropics and can not withstand low temperatures below 0 degrees Celsius; some species originally grow in warm climates and can withstand temperatures of-10 degrees Celsius. Can grow in all kinds of soil, most species can adapt to both acidic soil and alkaline soil, and the most suitable soil.
