Problems solved by technology

Affected by climatic conditions, grafting period, grafting method and other factors, the survival rate of grafted walnut seedlings is extremely unstable, reaching more than 90% when high, and less than 10% when low, and it is prone to variation, affecting the commerciality of the fruit
However, the tannin content in the walnut branch skin is high, and the grafting interface is easy to form an isolation layer during grafting. In some areas, the temperature in spring is low, and the healing of the grafting interface is slow. During the high temperature season in summer, the scion needs to be stored for a long time, resulting in poor survival rate of grafting. After surviving, the growth in the year is small, and the quality of seedlings is poor, which cannot meet the purpose of high-quality strong seedlings required for production

Embodiment 1

[0022] A kind of rapid cultivation method of walnut tree grafted seedling, specifically comprises the following steps:

[0023] ①Nursery site selection: choose a hillside with a flat altitude, leeward to the sun, deep soil, pH 7.5-8, and a hillside with a slope of 20-22° as the nursery base;

[0024] ②Nursery disinfection: deep plow the soil 20cm, mix wolfberry grass, houttuynia cordata, and scutellaria baicalensis leaves in a weight ratio of 2:1:1, and bury them after high-temperature carbonization treatment, then rake the soil finely; Leaves, Andrographis paniculata, and dried forsythia flowers are mixed in a weight ratio of 1:1:3, and then buried after high-temperature carbonization treatment, finely raked soil, covered with plastic film, and set aside;

[0025] ③Nursery field treatment: 15-20 days before sowing, remove the plastic film, turn over the soil, combine with turning over the soil to open horizontal ditches, the ditch depth is 40cm, and the distance between the d...

Abstract

The invention discloses a rapid cultivation method of Juglans regia grafted seedlings, and belongs to the technical field of agricultural planting. Before cultivation of the Juglans regia grafted seedlings, a nursery with alkaline soil is selected for cultivation of the Juglans regia grafted seedlings, and meanwhile disinfection, land preparation and fertilization are conducted on the nursery, sothat after the Juglans regia grafted seedlings are transplanted into the nursery, the seedlings absorb more nutrients, it is ensured that the Juglans regia grafted seedlings provide sufficient nutrients for scions, the survival rate of grafting is improved, and disease and pest resistance of the Juglans regia grafted seedlings is enhanced. The Juglans regia grafted seedlings undergo pot culture and then are transplanted to the nursery for sound seedling cultivation, so that not only is the wound healing capacity of the Juglans regia grafted seedlings improved, but also the stress resistance ofthe Juglans regia grafted seedlings is further reinforced, and the survival rate and disease and pest resistance of transplantation of the Juglans regia grafted seedlings into the alkaline soil afterlifting are improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, in particular to a rapid cultivation method for walnut tree grafted seedlings. Background technique [0002] Walnut (Juglans regia), also known as walnut, is a plant of the genus Juglans. Walnut seeds are rich in nutrition. According to measurements, every 100g of seed kernels contains 63.0g of fat, 15.4g of protein, 10.0g of carbohydrate, 5.8g of crude fiber, and 1.5g of ash. In addition, it also contains calcium, phosphorus, iron, potassium and other minerals and vitamins. The medicinal value of walnut is very high. Modern medical research believes that walnuts are warm in nature, sweet in taste, non-toxic, and have the effects of invigorating the stomach, nourishing blood, moistening the lungs, and nourishing the mind. Phospholipids in walnuts have a good health care effect on brain nerves; walnut oil contains unsaturated fatty acids, which can prevent and treat arterioscleros...
