我场现有果树24万余株,其中有5～8年生国光幼树17万株,结果晚、产量低,还有部分10余年生的成龄果树,单产只有三五斤。为了使这些幼树和成龄寡产树尽快丰产,我们与中国农科院果树研究所协作,用植物生长调节剂喷洒树冠,抑制营养生长,促进花芽形成。经过4年的多点试验,已筛选出两个最佳处方,增产效果十分明显
There are more than 240,000 fruit trees in our field, among which there are 170,000 guoguang trees aged 5 to 8 years old. The results are late and the yield is low. There are also some mature fruit trees with some 10 years old and only yielding 35kg. In order to make these young trees and mature widowed trees yield as soon as possible, we collaborated with the Institute of Fruit Trees of Chinese Academy of Agricultural Sciences to spray canopy with plant growth regulator to restrain vegetative growth and promote flower bud formation. After 4 years of multi-point test, the two best prescriptions have been screened, and the stimulation effect is very obvious
