Greenhouse fig cutting propagation seedling nursing method

Abstract

The invention discloses a greenhouse fig cutting propagation seedling nursing method. A fig current-year semi lignification branch with 15cm long work as a cutting slip; the lower end of the cutting slip is disinfected and immersed into ABT root growth prompting agent with concentration of 800mg/L; in an optimized daylight greenhouse, an electric heating wire is paved on the internal bottom of a bed, so temperature difference of 10 to 15 DEG C can be achieved between the bottom and external environment; the well-processed cutting slips are inserted into cutting slip base material mixed by turf, decomposed cow dung, vermiculites, perlites and bone meal; after the cutting, water content of the greenhouse can reach 20 to 25% due to full-light exposure mist spraying management; after cutting, leaf fertilizer is sprayed once to No.45d, No.60d and No.75d cutting slips; and then normal management is conducted. Survival rate of the fig seedling can reach over 95% by the use of the greenhouse fig cutting propagation seedling nursing method; cutting slip callus and adventitious root apparition is shortened; in particular, the method most favors the cutting slip seedling callus; rooting numbers, root length and rooting rate can be improved; seedling stress resistance capability can be enhanced; and fig seedling healthy growth can be prompted.

Description

technical field [0001] The invention belongs to the field of fruit tree cultivation, and relates to a method for growing seedlings of fig cuttings in a greenhouse. Background technique [0002] Fig (Ficus carica L.) is a perennial fruit tree of the genus Ficus genus Moraceae. It is native to Mediterranean countries and is one of the oldest cultivated fruit trees in the world. It has a long history of cultivation in Xinjiang, Shandong and other places in my country. Inflorescence head, so it is called "fig". Its fruit, stem, leaf and other vegetative organs are rich in various amino acids, vitamins, polysaccharides and other important components of human balanced diet. It has edible, medicinal and ornamental values, and has broad prospects for development and utilization. As a traditional fruit tree seedling breeding method, cutting propagation is an important way for fig seedling breeding, especially with the artificial synthesis of auxin and the application of automatic spr...
