小编摘要:Particularity of contradictions ----treat different things and persons with different manners.Not all the plants or vegetables need so much sunshine .


Not all vegetables need lots ofsunshine. Mark Hoffman and his wife, Guia, own a bed-and-breakfast guest house in rural Kempton, Illinois. They often serve their guests produce fresh fromthe garden.


The Hoffmans have been growing food and flowers for twenty-five years. For almost ten of those years, Mr. Hoffman hasbeen experimenting and working with shade plantings. He says visitors to hiswebsite -- -- often ask how to plant in shade spaces.


MARK HOFFMAN: "The bottom linehere is that most plants will produce more in full sun. But if you do not havefull sun, there are other options."


For example, he grows tomatoes near oaktrees. Oak trees can produce a lot of shade. But Mr. Hoffman says his tomato plants grow as long as they get five hours a day of direct sunshine, especially morning sun.


Not only does this go against the traditional advice that tomatoes need six, eight, even twelve hours a day offull sun. It also shows how plants and tree roots can share nutrients andwater.


Mr. Hoffman also planted asparagus around a tree at its drip line, the area below the outer limit of the branches.


MARK HOFFMAN: "Now the asparagusis in partial shade. It has been there for six years now and is doing wonderfully. It is right at the drip line of the tree. So when it rains, allthe rain drips down right on the asparagus."


The Hoffmans' website includes a listof vegetables, flowers and herbs that have produced acceptably for them inpartial shade. Besides tomatoes and asparagus, these include broccoli,daylilies, horseradish, Irish potatoes, oregano and winter onions.


Mr. Hoffman says plants with widerleaves seem to do better in shady environments. He also found that his potatoes did better in partial shade than in full sun.


Moving them out of the sun helpedcontrol an insect problem with leaf hoppers. Mr. Hoffman does not use pesticides. Instead, he planted the potatoes at the drip line, especially onthe east side of the tree.


The potatoes get morning sun, but theyare shaded during the hottest part of the day. Leaf  hoppers dislike shade, and the hottest part of the day is when they do the worst of their damage.


Time of day. Brightness of the sun.Shadows from trees, walls and buildings. These all influence how much sunlight falls, or does not fall, on plants. And extension agent Curtis Swift atColorado State University says people interested in shade planting should alsoremember something else. The term "shade" can describe differen tamounts of darkness. He says it can even mean different things in different parts of the world.

一天中的时段,阳光的强度,树木、墙壁和建筑的阴凉,这些都影响到植物的日照情况。科罗拉多州立大学推广员柯蒂斯·斯威夫特(Curtis Swift)表示,对荫凉种植有兴趣的人们还需要记住其它一些事情。他说,“荫凉”还分不同程度,它甚至意味着世界上不同的地方各有不同。
