Method for promoting young branch cuttage seedling cultivation of Nata oak

Abstract

The invention discloses a method for promoting young branch cuttage seedling cultivation of Nata oak, relating to the technical field of propagation of Nata oak. The method mainly comprises the following steps: 1) establishing a cuttage pool; 2) cutting, namely selecting the morning of a rainy day or a sunny day, cutting the branches which are semi-lignified in the current year from a harvesting garden, and cutting the branches into 8-12 pieces of cuttings; 3) treatment of cutting: soaking the cut cutting with rooting agent prepared from mixed solution of 500mg / L indolebutyric acid, 250mg / L naphthylacetic acid and 50mg / L phloroglucinol for 1h; 4) cuttage: cutting the treated cuttage, and watering the cuttage to ensure that the base of the cutting is tightly combined with the matrix; 5) management after cuttage. After rooting, the plastic films at the two ends of an arched shed are opened, and the cuttage seedlings can be transplanted to a field or a container in the spring of the nextyear. The cuttage method is simple and rapid to operate, can cultivate a large number of high-quality Nata oak seedlings in a short time, has wide application prospect, has good practical applicationvalue, and can generate good economic benefits and social benefits.

Description

technical field [0001] The invention relates to the technical field of Quercus nata propagation technology, in particular to a method for promoting the cutting seedling cultivation of Quercus nata twigs. Background technique [0002] Quercus nuttallii is a deciduous tree of the Fagaceae Quercus genus, native to the low-lying coastal plains from west Florida to southeast Texas. Its trunk is upright, the bark is gray or brown, the crown is tower-shaped, and the tree shape is beautiful. The leaves begin to turn red or yellow in early November every year. It is an excellent color-leaved tree species in autumn and winter and has great ornamental value. In production, Quercus nata is mainly propagated by seeds, but its seeds have obvious dormancy, and it takes more than 3 months of low-temperature stratification to release dormancy, which brings certain difficulties to the production of seedlings; on the other hand, Its seeds all rely on foreign imports and are expensive, resulti...
