激素乙烯利是一种植物生长调节剂,由于它能被植物的茎、叶、果实等器官很快吸收,并释放出乙烯,从而能调节果树的代谢、生长和发育,达到优质丰产的目的,国外已在生产上广泛应用。据国内外报导,它在果树方面有减少顶端优势、催熟、增产等作用。乔化砧苹果的矮化密植栽培首先就要研究如何控制缩小树冠,以达到密植的要求;同时还必须做到在密植的条件下,早结果、多结果,产量稳定,省工,适于机械化操作。乙烯利能否有助于达到上述要求,我们遵照毛主席“一切经过试验”的教导,开展了这方面的试验,现将试验情况总结如下。
Hormone ethephon is a plant growth regulator, because it can be plant stems, leaves, fruits and other organs quickly absorbed and release of ethylene, which can regulate the metabolism of fruit trees, growth and development, to achieve high yield and quality purposes, Abroad has been widely used in production. According to reports both at home and abroad, it has the effect of reducing the top advantage, ripening and increasing yield in fruit trees. First of all, we should study how to control the shrinking canopy so as to meet the requirements of close planting. At the same time, we must also make the early result, the multi-result, the stable output, the labor saving and the mechanization operating. Whether ethephon can help meet the above requirements, we follow Chairman Mao’s “all tested” teaching, carried out in this area test, the test is summarized as follows.
