Embodiment 1

[0024] (1) Grafting time: February 2-5, 2012.

[0025] (2) Marriage site: Liujia Mountain, Xialiujia Village, Wenquan Township, Changning County, Yunnan Province.

[0026] (3) Prepare peat moss: Harvest peat moss manually in the wet forest or marsh wetland around the grafting ground, and remove impurities such as sediment, dead branches, fallen leaves, and weeds. On the day of grafting, wet the peat moss with natural spring water or river water, so that the moisture content of the peat moss reaches 10-15%.

[0027] (4) Scion cutting: Select the 1-year-old branch of "Dapao walnut" as the scion, choose the branch with full bud body, full and strong, small pith, and no pests and diseases, and cut it with small branch shears or tall branch shears. The branches are wrapped in sphagnum moss and can be picked the same day without wax sealing.

[0028] (5) Grafting: cut the iron walnut rootstock with a diameter of 3-8cm at a distance of 50-60cm from the ground with a hand saw, selec...

Embodiment 2

[0036] (1) Grafting time: February 17, 2013.

[0037] (2) Marriage site: Youwen Village, Tianyuan Town, Changning County, Yunnan Province.

[0038] (3) Prepare sphagnum moss: Harvest sphagnum moss artificially in the wet forest or marsh wetland around the grafting ground, and remove impurities such as sediment, dead branches, fallen leaves, and weeds. On the day of grafting, wet the peat moss with natural spring water or river water, so that the moisture content of the peat moss reaches 10-15%.

[0039] (4) Scion clipping: Select "Xianxiang Walnut" 1-year-bearing branch as the scion, choose branches with full buds, full and strong, small pith, and no pests and diseases, and cut them with small branch shears or tall branch shears. The branches are wrapped in sphagnum moss and can be picked the same day without wax sealing.

[0040] (5) Grafting: Saw the iron walnut rootstock with a diameter of 8-12cm at a distance of 60-70cm from the ground with a hand saw, and cut a grafting...

Embodiment 3

[0048] (1) Grafting time: February 22, 2013.

[0049] (2) Place of marriage: Wanggang Village, Datianba Township, Changning County, Yunnan Province.

[0050] (3) Prepare sphagnum moss: Harvest sphagnum moss manually in the wet forest or marsh wetland around the grafting ground, and remove impurities such as sediment, dead branches, and weeds. On the day of grafting, wet the peat moss with natural spring water or river water, so that the moisture content of the peat moss reaches 10-15%.

[0051] (4) Scion cutting: Select the 1-year-old branch of "Xianxiang walnut" as the scion, choose the branch with full bud body, full and strong, small pith, and no pests and diseases, and cut it with small branch shears or tall branch shears. The branches are wrapped in sphagnum moss and can be picked the same day without wax sealing.

[0052] (5) Grafting: Saw off the iron walnut rootstock with a diameter of 10-15cm at a distance of 60-70cm from the ground with a hand saw, select a straigh...

Abstract

The invention discloses a method for absorbing bleeding exudation of walnuts through sphagnum palustre to increase the stem grafting survival rate. The method comprises the following steps of (1) selecting grafting time; (2) preparing the sphagnum palustre; (3) scissoring a scion; (4) performing graft; (5) wrapping the grafting position by the sphagnum palustre; (6) arranging a guide bar; (7) binding up the grafting union; (8) processing a stock; (9) unbinding a grafting membrane. By wrapping the grafting position by the sphagnum palustre and arranging the guide bar, bleeding exudation can be absorbed and discharged effectively, injury to the grafting union and the scion due to gathering of a large amount of the bleeding exudation is avoided, temperature and humidity suitable for growth of callus are provided, and the stem grafting survival rate of the walnuts is increased. Tests prove that under the same grafting technological level, the grafting survival rate of the method reaches 91.2 percent- 94.7 percent and is 8 percent- 13 percent higher than that of the traditional grafting method, the bleeding exudation affecting grafting survival of the walnuts is effectively removed, and therefore, the method has wide application prospect in production.

Description

technical field [0001] The invention belongs to the technical field of fruit tree grafting, in particular to a method for absorbing walnut wounds with sphagnum moss and improving the survival rate of walnut grafting. Background technique [0002] Injury is the main reason for the low survival rate of walnut grafting. Excessive wound fluid will cause hypoxia at the grafting interface, inhibit the respiration and callus formation at the rootstock-ear interface, and reduce the survival rate of grafting; The interface and scion are moldy and rotten, and the callus is difficult to form, resulting in graft failure. Therefore, solving the wound problem is the key to improving the survival rate of walnut grafting. [0003] At present, the method for overcoming walnut tree injury has been documented, and a kind of is to cut deep at the base of the rootstock and carry out water treatment, so that the injury flow flows out from the bottom of the rootstock; Buds, thereby reducing wou...
