We often think of agriculture as planting seeds and harvesting crops. But many crops do not come from seeds. Many kinds of trees and plants are grown from【D1】______cut from existing trees and plants. This is called grafting (嫁接).
Farmers cut branches or young growths, called【D2】______, from one plant and place them on a related kind of plant. The branch or bud that is grafted is called a scion (接穗). The plant that【D3】______the graft is called the rootstock. Over time, the【D4】______from the two plants grow together. The grafted plant begins to【D5】______the leaves and fruit of the scion, not the rootstock.
A graft can be cut in several ways. A cleft graft (割接,劈接), for example, requires a scion with several buds on it. The bottom of the scion is cut in the【D6】______of the letter V. A place is cut in the rootstock to accept the scion. The scion is then【D7】______placed into the cut on the rootstock. Growth medium is put on the【D8】______to keep it wet and help the growth.
Grafting can join scions with【D9】______qualities to the rootstock that is strong and resists disease and insects. Some common fruit trees such as sweet cherries have to be grafted.
In an age of high-technology agriculture, grafting is a low-technology method that remains【D10】______important.
A) accepts F) desirable K) parts
B) agreeable G) extremely L) pieces
C) blossoms H) gradually M) produce
D) buds I) grow N) securely
E) composes J) joint O) shape [br] 【D9】
选项
答案
F
解析
根据句子结构可知,此处可填入形容词,修饰后面的名词qualities。由句意可知,此处讲的是嫁接的好处,结合后面提到砧木的抗病和抗虫,推出接穗要具有某些好的特性,故F)desirable为答案。
