Embodiment 1

[0044] Step 1. Slotting bed preparation: Choose a water-proof container with a width of 2m, a depth of 15cm, and an unlimited length for the slotting machine. Spread 5cm of fine river sand on the bottom of the slotting bed, and then put in clear water to a depth of 3cm to form a water bed.

[0045] Step 2, selection of seedlings: select the branches on the 1-year-old seedlings of the excellent variety of river willow, with a diameter of 0.4-1.5cm, the seedlings or branches are strong and free of diseases and insect pests, and the side buds are full.

[0046] Step 3, cutting cuttings: cut the seed strips short to make cuttings, each cutting is 6.0-8.0cm long. The upper part of the cuttings is truncated, retaining 1 leaf bud, the bottom is truncated or obliquely cut, and the cut is smooth.

[0047] Step 4. Cutting: Insert the cuttings of the river willow into the fine river sand of the water bed for 3-5cm, and the terminal buds shall be exposed to the water surface. The cuttin...

Embodiment 2

[0052] Step 1. Slotting bed preparation: Choose a water-proof container with a width of 2m, a depth of 20cm, and an unlimited length as the slotting machine. In the greenhouse, dig soil directly to build a low bed, with a width of 2m, a depth of 20cm, and any length, and a plastic film is used to pad the bottom and side of the bed to prevent water seepage. Spread 4cm of fine river sand on the bottom of the slotting bed, and then put in clear water to a depth of 4cm to form a water bed.

[0053] Step 2, selection of seedlings: choose the branches on the 2-year-old seedlings of the excellent variety of river willow, with a diameter of 0.4-1.5cm. The seedlings or branches are strong and free of diseases and insect pests, and the side buds are full.

[0054] Step 3, cutting cuttings: cut the seed strips short to make cuttings, each cutting is 6.0-8.0cm long. The upper part of the cuttings is truncated, retaining 1 leaf bud, the bottom is truncated or obliquely cut, and the cut is...

Embodiment 3

[0060] Step 1. Slotting bed preparation: Choose a water-proof container with a width of 1m, a depth of 15cm, and an unlimited length for the slotting machine. Spread 3cm of fine river sand on the bottom of the slotting bed, and then put in clear water to a depth of 3cm to form a water bed.

[0061] Step 2, selection of seedlings: choose the branches on the 2-year-old seedlings of the excellent variety of river willow, with a diameter of 0.4-1.5cm. The seedlings or branches are strong and free of diseases and insect pests, and the side buds are full.

[0062] Step 3, cutting cuttings: cut the seed strips short to make cuttings, each cutting is 6.0-8.0cm long. The upper part of the cuttings is truncated, retaining 1 leaf bud, the bottom is truncated or obliquely cut, and the cut is smooth.

[0063] Step 4. Cutting: Insert the cuttings of the river willow into the fine river sand of the water bed for 3-5cm, and the terminal buds shall be exposed to the water surface. The cuttin...

Abstract

The present disclosure relates to a method for improving the rooting rate of cutting of salix chaenomeloides. The method comprises the following steps: (1) preparation of a cutting bed: selecting a leakage-proof container as a cutting bed, laying fine river sand at the bottom of the cutting bed, and pouring water to form a water bed; (2) selection of nursery stock: selecting the branches of 1 to 2years-old nursery stock of the salix chaenomeloides and having a diameter of 0.4 to 1.5 cm; (3) preparation of cutting slips; (4) cutting; (5) management after cutting; and (6) nursery stock transplant. The method can fully utilize the hydrophilic characteristics of the salix chaenomeloides, improves the rooting rate of cutting and the seedling survival rate of the salix chaenomeloides hydroponiccutting, overcomes the low rooting rate of cutting of the salix chaenomeloides in the soil, overcomes the problem in the traditional hydroponic cutting that the cutting slips are difficult to fix soas to cause time-consuming and labor-intensive issues, improves the rooting rate of cutting of the salix chaenomeloides to over 90%. Because of asexual reproduction, the method can fix the traits of salix chaenomeloides, and is very suitable for the rapid expansion of new varieties of salix chaenomeloides with less nursery stock.

Description

technical field [0001] The disclosure relates to the technical field of cutting propagation of seedlings, in particular to an asexual propagation technology for improving the rooting rate of cuttage seedlings of the difficult-to-root willow species Helius chinensis. Background technique [0002] The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] There are more than 500 kinds of willows. Different willow species have different degrees of difficulty in rooting cuttings in the soil. Cuttings such as white willow, weeping willow, and salix are easy to root, and the rooting rate is generally over 90%, while cuttings in river willow are more difficult to root in soil. , The rooting rate is generally between 50-60%. The use of seeds for the propagation of river willow seedlings has problems such as difficult collection of seeds, short storage time of seed vigor, large variation in the...
