Embodiment 1

[0036] The experiment of proanthocyanidin treatment to promote the rooting and growth of Guimu No. 1 hybrid elephant grass cuttings under artificially controlled environmental conditions, the main steps are as follows:

[0037] 1) Selection and cutting of cuttings: On February 25, 2017 (sunny day), the seed stems of Guimu No. 1 hybrid elephant grass that were kept green in winter storage were selected as test materials, and one stem node was reserved for each cutting. Leave 1 / 3 for the lower part of the node, 2 / 3 for the upper part, and cut the segment into a bevel ( figure 1 );

[0038] 2) Cutting treatment: Cuttings are soaked in proanthocyanidin treatment solution with 5 concentration gradients (0, 50, 100, 150, 200 mg / L). Take out and filter dry; CK is the control of direct rooting without soaking; 100 cuttings per treatment;

[0039] 3) Cutting culture: The processed cuttings, each bundle of 10 cuttings, are placed in a plastic box (30cm×22cm×12cm) with 1 / 2 Hoagland’s c...

Embodiment 2

[0046] To verify the rooting test of proanthocyanidins in the treatment of Guimu No. 1 hybrid elephant grass seed stems under the natural environment conditions of the field, the operation steps are as follows:

[0047] 1) Selection and cutting of cuttings: It was carried out on February 25, 2017 (sunny day) at the grass industry base of Hunan Institute of Animal Husbandry and Veterinary Medicine, and the stems of Guimu No. 1 hybrid elephant grass that were kept green in winter storage were used as test materials , keep 1 stem node for each section of cuttings, leave 1 / 3 of the lower part of the stem node, leave 2 / 3 of the upper part, and cut the segments into oblique planes ( figure 1 );

[0048] 2) Cutting treatment: Cuttings are soaked in proanthocyanidin treatment solution with 5 concentration gradients (0, 50, 100, 150, 200 mg / L). Take out and filter dry; CK is the control of direct rooting without soaking; 100 cuttings per treatment.

[0049]3) On the same day, cuttage...

Abstract

The invention discloses a method of promoting fast and healthy cutting and rooting of hybrid napiergrass Guimu No.1 and relates to the technical field of vegetative propagation of herbage. The method comprises following steps: (1) selecting and segmenting of cuttage; (2) processing of cuttage; (3)-1 under natural field environment, processing the cuttage for rooting with proanthocyanidins; (3)-2 under manual control environment, processing the cuttage for rooting with proanthocyanidins. By means of the method of promoting fast and healthy cutting and rooting of hybrid napiergrass Guimu No.1 of the invention, there are more adventitious roots and newly grown capillary roots are promoted; the method greatly improves the rooting rate of cuttings, promotes the healthy growth of cuttings, increases the propagation rate of cuttings roots, and increases the transplanting survival rate. The method is simple, cheap, low cost and easy to operate, and is suitable for cuttage of asexual reproduction herbage such as the Chinese pennisetum series with high economic benefits.

Description

technical field [0001] The invention relates to the technical field of forage vegetative propagation, in particular to a method for promoting rapid and healthy cutting rooting of Guimu No. 1 hybrid elephant grass. Background technique [0002] Guimu 1 Hybrid Elephant Grass [(Pennisetum americanum×P.Purpureum)×P.Purpureumschum.cv.Guimu No.1] is a hybrid pennisetum (P.americanum×P.Purpureum) The female parent, Dwarf Elephant Grass (P. Purpureum cv. mott) is the male parent, which was bred by sexual hybridization. It was approved and registered by the National Forage Grass Breeding Committee in 2000 (variety registration number 211). Guimu 1 Hybrid Elephant Grass is a perennial herb species with tall erect stems, many tillers, large leaf volume, warm and humid climate, high yield, long useful life, and almost no pests and diseases. The main species of tall grasses cultivated in southern China are mainly propagated by the cutting method of cut stems. Before planting, select th...
