Method of root cuttage of fast-growing locust trees in greenhouse

Abstract

The invention discloses a method for root cuttage of fast-growing locust trees in a greenhouse. The method comprises the following steps of preparing a seedling bed, preparing and placing nutrition bags, preparing cutting slips, carrying out chemical treatment, cutting, and managing the greenhouse after cutting: shading, spraying water, controlling temperature, preventing and controlling insect diseases, and outplanting. The method provided by the invention selects river sand as a matrix so as to be economical and practical, the conditions of the seedling bed can be met, and water retention and ventilation are realized; the roots are cut, so that the survival rate is high; meanwhile, appropriate rooting hormone is compounded, so that the optimal concentration and the optimal treatment time are modulated, rooting can be carried out smoothly, and the large-scale breeding of the fast-growing locust trees is effectively realized.

Description

technical field [0001] The invention relates to the technical field of tree cutting propagation, in particular to a method for root cutting of fast-growing locust trees in greenhouses. Background technique [0002] Fast-growing locust tree is a deciduous tree of the genus Robinia in the family Fabaceae, 10-25 meters high; the bark is taupe to dark brown, lobed to deeply longitudinally lobed, thin and smooth. Branchlets grayish brown, with ridges when young, slightly hairy, then glabrous; with stipules, up to 2 cm; winter buds small, hairy. Pinnate compound leaves 10-25(-40) cm long; rachis covered with grooves; leaflets 2-12 pairs, often opposite, elliptic, oblong or ovate, 2-5 cm long, 1.5-1.5- 2.2 cm, apex round, slightly concave, with small pointed tip, base round to broad cuneate, margin entire, green above, gray-green below, pubescent when young, then glabrous. Corolla white, each petal with stalk, flag petal nearly round, 16 mm long, 19 mm wide, apex notched, base ro...

Problems solved by technology

[0016] At present, there are many methods for the propagation of fast-growing Sophora japonica, but there are still few methods that can ensure its high survival rate and achieve large-scale propagation.
