Analysis on the main points of walnut seedling raising technology! How much is a walnut seedling? What high-quality varieties do you have?

Walnut, also known as Qiangtao, Hetao and Wanshizi, belongs to the walnut family. It has high nutritional value and is mainly cultivated in plain and hilly areas. In walnut production, walnut seedling raising is a key step. What are the walnut seedling raising techniques? How much is it per plant?

1. Techniques for raising walnut seedlings

1. Seed selection: seed quality is the basis for determining the success or failure of raising seedlings, so walnut seedlings should first select good seeds, and walnuts with full growth should be selected for seed use.

2. Seed treatment: the selected walnut seeds should be soaked 7-10 days before sowing. During the treatment, the selected walnut seeds were soaked in cold water, changed water every day, soaked for 2-3 days, exposed to the sun for 1-2 hours, and then soaked. After 7-10 days, almost all the walnut seeds could be cracked, and the seeds could be sowed at this time.

3. Soil preparation: walnut is suitable for growing in the soil with flat terrain, fertile soil and good drainage. The soil should be ploughed deeply before sowing, and the general tillage depth should be between 30cm and 40cm. At the same time, throw away stones, grass roots and other sundries that affect the growth of walnut, and finally flatten it into a seedbed.

4. Fertilization: combined with deep ploughing, 4000kg of soil fertilizer, 15kg of urea, 20kg of diammonium phosphate, 15kg of ferrous sulfate and 2.5 kg of 3% phoxim were applied per mu.

5. Sowing: autumn sowing generally sows from late October to early November, while spring sowing usually sows in early April.

6. Sowing method: the general row spacing of walnut sowing is kept at 30cm to 50cm, the ditch depth is 10cm to 15cm, and one seed is sown every 15cm to 20cm. When sowing, the walnut seeds are graded according to the size of walnut seeds, and the suture line is better vertical to the ground, which is beneficial to seedling emergence.

7. Covering soil: after sowing, covering soil is about 5cm. If it is too thin, it will affect the emergence of seedlings, and if it is too thick, it will not help to emerge seedlings.

8. Seedling emergence management: from the emergence of ① walnut seedlings to August, the seedlings mainly do a good job of rodent and frost damage in winter, and disease and insect pest control in summer. ② weeding in time All ③ seedlings should be topdressing and watering, and topdressing watering should be carried out according to the principle of a small number of times, the first topdressing should be about 5 kg of urea per mu, and the maximum amount of urea should be controlled within 10 kg per mu, and it is best to take advantage of rain or watering; ④ should pick out the heart in time when the seedling height is about 30 cm; ⑤ should pay attention to control the supply of nitrogen fertilizer and water after August to improve tree resistance.

Second, how much is a walnut seedling?

1. Walnut seedlings

1.3 yuan under 30 centimeters

1.6-2 yuan of 30-75 cm

3-4 yuan for 0.8-2.5 meters

5-10 yuan for 1.8-2.5 meters.

2. Grafted walnut seedlings

2 yuan less than 30 centimeters

5 yuan of 30 to 45 centimeters

6 yuan in 50-75 centimeters

7-10 yuan for 0.8-2 meters.

Third, what are the high-quality varieties of walnut seedlings?

1. Fragrance

Qingxiang is an excellent variety of walnut presented to Hebei Agricultural University by Japanese walnut experts in the early 1980s. it is a variety with early fruit and high yield in late bearing walnut. Fragrant walnut has the advantages of medium demand for fertilizer and water, easy management, 3-year fruit and 5-year high yield. it is an excellent variety between early-bearing walnut and late-bearing walnut.

2. Xiang Ling

Xiangling walnut was bred by Shandong Fruit Tree Research Institute. Xiangling walnut is cold-resistant, drought-resistant, wind-resistant and disease-resistant. It is suitable for planting in areas with deep soil layer, and can be developed in a large area in North China, Northwest, Southwest and South Northeast.

3. Liaohe No.1

Liaohe No. 1, also known as Liaoning No. 1, was bred by Liaoning Economic Forestry Research Institute. It blossomed in the first and middle of May and the nuts matured in late September. Liaohe No. 1 has strong adaptability, high yield and high quality, which is an early fruiting variety with strong branching ability and early fruit. it is not suitable to bear fruit in the period of tree cultivation in the first three years, and began to produce fruit in the fourth year, which is most favorable for development in gentle slope and hilly areas.

4. 8518 walnut seedlings

8518 walnut seedling refers to the 18th bud variety selected in 1985. 8518 Walnut seedlings have strong high yield, and the yield in the later stage is also very stable. The yield in the high yield period is as high as 1100 jin. The nuts are of good quality, easy to manage, disease resistance, storage resistance, disaster resistance and convenient to eat.

5. Shaanxi Nuclear No.5

Shanhe No. 5 is an early fruiting variety, which was selected by Shaanxi Fruit Tree Institute. Shanhe No. 5 tree is strong, more tolerant to drought and barren, with oblong nuts, large fruit and smooth fruit surface.

6. Guanhe No.1

Guanhe No. 1 is a thin-skinned walnut variety, which was successfully cultivated in 2011. The kernel rate of Guanhe No. 1 is more than 65%. It has strong early fruiting and high yield, and has the excellent quality of wind resistance, sun resistance, freezing resistance, disease resistance and less fruit drop.

7. Guanhe No.3

Guanhe No. 3 is characterized by a large head (slightly flat and round) with thin skin, full and beautiful kernels, oval nuts and full nucleoli. This variety has high fruit setting rate, disease resistance and high yield, so it is a variety with good development prospects.

Conclusion: the seedling technology of walnut is introduced here. If you want high yield of walnut, early management is very important. We must manage scientifically, select the right variety and cultivate according to the standard technology.
