Embodiment 1

[0016] (a) Polyvinyl alcohol cooking method: use a pot to boil water to about 50°C, then add polyvinyl alcohol (polyvinyl alcohol: water = 1:15), stir as you add, until the pot boils, and continue to boil with a slow fire 20min, let it cool to room temperature before use.

[0017] (b) Period of polyvinyl alcohol smearing: in early November, after the leaves of walnut saplings fell and before freezing.

[0018] (c) Polyvinyl alcohol smearing method: use boiled polyvinyl alcohol to evenly smear the trunk of the young tree above the grafting joint (including the grafting joint).

Embodiment 2

[0020] (a) Polyvinyl alcohol cooking method: use a pot to boil water to about 50°C, then add polyvinyl alcohol (polyvinyl alcohol: water = 1:18), stir as you add, until the pot boils, and continue to boil with a slow fire 25min, let it cool to room temperature before use.

[0021] (b) Polyvinyl alcohol smearing period: in early November, after the young walnut trees have fallen leaves and before freezing.

[0022] (c) Polyvinyl alcohol smearing method: use the boiled polyvinyl alcohol to evenly smear the trunk of the young tree above the grafting interface (including the grafting interface).

Embodiment 3

[0024] (a) Polyvinyl alcohol cooking method: use a pot to boil water to about 50°C, then add polyvinyl alcohol (polyvinyl alcohol: water = 1:20), stir as you add, until the pot boils, and continue to boil with a slow fire 30min, let it cool to room temperature before use.

[0025] (b) Polyvinyl alcohol smearing period: in early November, after the young walnut trees have fallen leaves and before freezing.

[0026] (c) Polyvinyl alcohol smearing method: use the boiled polyvinyl alcohol to evenly smear the trunk of the young tree above the grafting interface (including the grafting interface).

Abstract

The invention discloses a winter freeze-proof method of a walnut sapling. The method comprises that a pot is used for burning the water to about 50 degrees, and then polyvinyl alcohol can be added. After that, the liquid is mixed until the liquid is boiled. Slow fire can be used for heating the liquid in 20-30 minutes. After the liquid is cooled to an indoor temperature, the liquid can be used. The boiled polyvinyl alcohol can be used for painting uniformly a main trunk of a sapling. The method can be used for prevent the walnut sapling form water loss and stripping so as to enable walnut saplings to be safe to overwinter.

Description

technical field [0001] The invention relates to the technical field of tree antifreeze protection, in particular to a winter antifreeze method for young walnut trees. Background technique [0002] Walnut tree, the general designation of the Juglandaceae Juglans (scientific name Juglans) plant, originates in Central Asia. Hebei Province is a traditional walnut producing area with a long history of cultivation. According to textual research, the walnut fossils unearthed in Cishan, Wu'an City are about 7,000 years old. The famous Shimen walnut in history is produced in Lulong, Hebei. At present, there are thousands of walnut trees over one hundred years old in Shexian, Laiyuan, Lulong and other counties. In 2007, the cultivated area of ​​pecans in Taihang was more than 870,000 mu, with a total output of 40,273 tons; in 2011, the cultivated area of ​​walnuts in Hebei Province was 144,000 ha 2 (2.2 million mu), with an output of 96,900 tons. However, the occurrence of walnut f...
