Method for quick cultivation of stock of long-stem tree-like rose and quick cultivation of long-stem tree-like rose using cutting with long shoots

Abstract

The invention relates to a method for quick cultivation of long-stem standard rose using cutting with long shoots. A stock of the long-stem standard rose to be cultivated by the method is a shoot of rosa multiflora Thunb. var. carnea Thory, which is dipped with rooting powder for cuttage, the rooting powder is made of IBA (indole-3-butyric acid) 0.8-1.0% and thiophanate-methyl 2-5%, mass water content of substrate soil is maintained to be 60-65% after cuttage, relative humidity of air in a seed bed is 60-80%, the relative humidity of the air is reduced to 50-60% after a cutting seedling rootsand sprouts, daytime temperature is controlled to be 25-26 DEG C, night temperature is controlled to be 10-14 DEG C, a black shade with light transmittance 50% is used for covering from 11 O'clock to17 O'clock in two weeks after rooting and sprouting, the black shade is removed after two weeks, daytime temperature is then controlled to be 26-28 DEG C, and the rose shoot or bud is grafted to the stock. The stock has average height 120cm and only requires 135-150 days, and cultivation of the long-stem standard rose only requires 225-270 days, so that production cycle is short.
