Although thin-skinned walnuts have the advantages of early results, rapid increase in early production, and high kernel yield, relatively speaking, their ability to resist low temperatures is relatively poor, and cold-proof measures must be taken in winter.
1. Trees under 3 years old should be coated with polyvinyl alcohol. The ratio of polyvinyl alcohol: water=1:15～20 is boiled. The method is to first boil the water to about 50℃ in a pot, then add polyvinyl alcohol, stir with the addition until the pot is boiled, and then simmer for 20～30. After a few minutes, the trunk and branches of the tree can be evenly painted after the temperature is warm.
2. Trees over 3 years old should be painted white to prevent cold. The formula is: 6 parts quicklime, 18 parts water, 1 part lime sulfur mixture, 1 part salt, 0.2 parts edible oil. When preparing, first use half of the hydration to dissolve the lime and salt, then add the lime sulfur mixture, edible oil, and water, and mix well. When painting white, both the main stem and main branches should be painted.
3. In order to prevent the saplings from sprawling in winter, spray 150 times of dimethylol cellulose twice in January and February, pay attention to spray after the sun is out.

- Protein (e.g. protein powder)

- Various vitamins (such as vitamin A, B vitamins, vitamin C, vitamin D, vitamin E, etc.)
- Minerals (e.g. calcium, iron, zinc, selenium, etc.)
- Dietary fiber
- Other specific nutrients, such as Amino Acids, enzymes, probiotics, plant extracts, etc
The purpose of nutritional supplements is to meet the nutritional deficiencies that individuals may have due to special needs, dietary habits, digestive and absorption problems, health conditions (such as disease, pregnancy, aging, etc.) or other reasons. They are usually available in the form of tablets, capsules, oral liquids, powders, etc.
When choosing a nutritional supplement, one should consider an individual's physical condition, diet, and possible side effects. Although nutritional supplements can provide additional nutrients, it does not mean that they are a substitute for a balanced diet. The best strategy is usually to get most of your nutrients through a varied diet and use nutritional supplements when necessary under the guidance of a medical or professional. In addition, excessive consumption of certain nutritional supplements may also pose health risks, so it is recommended to consult a professional before use.
