Method for cutting and propagating creeping stems of primula pseudodenticulata pax view

Abstract

The invention provides a method for cutting and propagating creeping stems of primula pseudodenticulata pax view. The method comprises the following steps of: cutting the creeping stems picked from the primula pseudodenticulata pax view plant into 1 / 3 leaves, cutting the young seedlings with the stem length of 5 to 6cm into the matrix with the thickness of 8 to 10cm and the following mass ratio: garden soil: humus soil: perlite is equal to 1:1 to 2:1 to 2, the cutting depth is controlled to 3 to 4cm, the cutting density is better to non-overlap the leaves of the cutting young seedlings, the matrix is watered thoroughly after cottage, plastic films and sunshade screens are used for covering, management after cottage is carried out according to the conventional manner, and the hardening offof the seedlings can be carried out after 20 to 25 days. The method not only has easy seedling cutting and large amount, but also has easy cuttage, fast propagating speed, obtains strong hardened-offseedlings with strong insect prevention and disease resistance, has the survival rate of 60 to 70 percent after transplantation, is beneficial to industrial development of the primula pseudodenticulata pax view and has wide market prospect.

Description

technical field

[0001] The invention relates to a method for cutting and propagating stolons of Dianhai sea nymphs, belonging to the technical field of plant cultivation. Background technique

[0002] Primula pseudodenticulata Pax is a perennial herb of Primulaceae Primulaceae, and the whole plant is glabrous. The rhizome is very short, and stolons can grow from the top.
