Do you know how to plant a tree? Once you’ve chosen a tree, you’ll need to prepare your place for planting.
Planting the Tree
Dig a hole a foot deeper than and twice as wide as the root ball of the new tree. Loosen the soil at the bottom and sides of the hole, so roots will be able to easily enter the soil.
Gently remove the tree from the container and guide the tree into the hole. Build soil up and around the roots if necessary, so the tree is at the same soil level as it was originally grown.
Straighten the tree in the hole. Before you begin filling, have someone view the tree from several directions to confirm that the tree is straight. You should fill the hole with existing soil that has been mixed with rich materials. At this time you can also add bone meal and then water the tree.
Caring for the Tree
Caring for the tree once it is planted, is an important step so you should provide regular watering. Always feel the soil before watering, as over-wearing can also harm the tree. When soil is dry below the surface of the covering, it’s time to water. You will probably need to water at least once a week. Continue until mid-fall, when lower temperatures call for less-frequent watering.
When to Plant a Tree
Now that you know how to plant a tree, the next step is deciding when to plant. Spring and fall are generally the best times to plant a tree. This gives the tree time to adjusts(调整)before summer heat or winter cold arrives. In areas without cold winters, trees may be planted during the winter.

Researchers who use animals in psychological experiments must make every effort to minimize (最小化) discomfort, illness, and pain. And procedures that cause animals great suffering are permitted only when no other procedure is available. Moreover, there are federal regulations stating how animals art to be housed, fed. and preserved. Not only must researches try very hard to avoid causing physical discomfort, they are also required to promote the psychological well-being of some species of research animals, such as monkeys.
Why should animals be used for research in the first place? Is it really possible to learn about human behavior from the results of research employing rats and pigeons? The answer is that psychological research that does employ animals has a different focus and is designed to answer different questions than research that uses humans. For example, the shorter life span of animals (rats live an average of two years) allows researchers to learn about the effects of aging in a much smaller period than they could by using human participants. Moreover, some principles of behavior are similar across species, and so some basic behavioral phenomena can be studied more simply in animals. Finally, some studies require large numbers of participants that share similar backgrounds or have been exposed to particular environments—conditions that could not practically be met with human beings.
Research using animals has provided psychologists with information that has greatly benefited humans. For example, it provided the keys to noticing eye disorders in children early enough to prevent permanent damage
Despite the value of research with animal participants, the use of animals in psychological research is highly controversial. For example, some critics believe that animals have rights no less significant than those of humans, and that because animals are unable to agree to participation in studies, their use is not moral. Others object to the use of animals on methodological (方法论的) grounds, saying it is impossible to generalize from finding on nonhuman species to humans.
