“桃三、杏四、梨五年,枣树当年就还钱”。桃树从播种开始一般需5—6年才能生产。1990年春,我们应用地膜覆盖技术快速育苗,一年成苗,二年定植,四年见果,五年丰产。我们并探讨,总结出四年丰产的快速丰产栽培法。 “Peach three, apricot four, pears five years, jujube tree on the money back.” Peach trees generally require 5-6 years from sowing to produce. The spring of 1990, we applied rapid plastic film mulching technology seedlings, one year seedlings, planting two years, four years to see fruit, five years of high yield. We also explored and summed up the four-year fast-growing method of high-yield cultivation.
