Embodiment Construction
[0020] Specific embodiments of the present invention will be further described below. It should be noted here that the descriptions of these embodiments are used to help understand the present invention, but are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
[0021] A method for grafting walnuts, comprising the steps of:
[0022] S1, rootstock selection: choose fertile walnut seedlings that grow vigorously, are strong, and have no pests and diseases for more than two years as rootstocks; walnuts have strong affinity, strong growth potential, adapt to subtropical climates, and are suitable as rootstocks for walnut grafting.
[0023] S2. Scion selection and collection: select Yunxin 90301 walnut trees with high water content, full bud eyes, small pith core, high lignification, robust grow...

Abstract
The invention belongs to the technical field of fruit tree grafting, and particularly relates to a walnut grafting method. The walnut grafting method comprises the following steps: S1, rootstock selection; S2, scion selection and collection; S3, rootstock treatment; S4, scion treatment, S5, grafting; S6, management after grafting. In the grafting method, juglans sigillata which has high affinity and strong growth and adapts to subtropical climate is taken as a rootstock, so that the survival rate of grafting is increased; cut scion branches are placed at a shady place for 5 to 10 hours, so that tannin substances in the branches flow out, and the content of the tannin substances in the scion branches is reduced; the rootstock is scratched before grafting, so that the content of the tannin substances in the rootstock is reduced; during grafting, a composite plant growth regulating agent is sprayed onto a notch of the rootstock, and scions are dipped into the composite plant growth regulating agent, so that the formation of healing tissues is facilitated. By adopting the method provided by the invention, the survival rate of walnut grafting is increased remarkably, and the walnut grafting survival rate is up to 97 percent.
Description
technical field [0001] The invention belongs to the technical field of fruit tree grafting, in particular to a walnut grafting method. Background technique [0002] Walnut (Juglans regia), also known as walnut and Qiang peach, is a plant of the genus Juglans. Together with almonds, cashews and hazelnuts, it is called the "four major dried fruits". Walnut is a dried fruit with high nutritional value and rich in nutrients. According to the measurement, every 100g of walnut kernel contains 63.7g of high-quality fat, 14.6g of protein, 10.3g of carbohydrate, 280mg of phosphorus, 85mg of calcium, 2.6mg of iron, and 3.0g of potassium. mg, vitamin A 0.036mg, vitamin B 1 0.26mg, vitamin B 2 0.15mg, niacin 1.0mg and nicotinic acid 1.0mg, in addition, it also contains minerals such as manganese, chromium and vitamin K, etc., and is rich in lecithin, amino acids and unsaturated fatty acids, and does not contain cholesterol. Every 100g of walnuts can produce 268kJ of heat, which is ...
