为了获得苹果、杏、梨及其他果树的新的改良品种,很多园艺家们很久以前就在他们的工作中应用了嫁接。伟大的苏联学者米丘林便利用嫁接培养了二百多种果树的新品种。最近不仅有木本的嫁接,就连草本的嫁接也成为农业的实践。由於利用嫁接,培育了许多番茄和马铃薯的新品种,提高了很多种蔬菜的产量,把甜瓜、西瓜的种植区域向北(指苏联——译者注)推进了,获得了隐固的抗病的品种,缩短了各种不同植物的开花和结实的期限。当我们每个人在学校植物园中、在学校生物角中、在集体农场的实验田中或在自己家里的庭
In order to obtain new and improved varieties of apples, apricots, pears and other fruit trees, many horticulturalists have applied grafting to their work long ago. Michurin, a great Soviet scholar, used grafting to cultivate more than 200 new varieties of fruit trees.

Thanks to grafting, many new varieties of tomatoes and potatoes have been cultivated, yields of many kinds of vegetables have been raised, and planting areas of melons and watermelons have been pushed northwards to obtain secular disease resistance The breed shortens the flowering and fruiting periods of a variety of different plants. When each one of us is in a school botanical garden, in a school biology corner, in a field experiment in a collective farm, or in our own home
