Variety introduction:

It will bear fruit in the second year after grafting and start production in 3-4 years. The tree growth is moderate and the mother branch has strong branching ability. , (1:5.5), the fruiting branch force ratio reaches 90.4, the lateral flower bud rate reaches 81.7, the average width of the fruiting branches is 6 cm, the thickness is 0.8 cm, mainly medium and short branches bear fruit, the average fruit setting rate per fruiting branch is 1.3, the fruit setting rate higher. During the peak season in Shandong, the conservative yield of a single plant is generally 8-12 jins. With good management, water and fertilizer, it can produce 12-15 jins. The specific yield is related to management and geographical conditions, and is suitable for intensive and dense planting cultivation.

The tree is of medium vigor, upright, with a cylindrical crown, strong branching force and secondary growth. It is a male-first type and a medium-maturing variety. It begins to bear fruit in the second year of planting and enters the fruiting period in the fifth year. If dense planting and high-yield cultivation are carried out and scientifically managed, the yield per mu can reach more than 1,000 kilograms. The fruiting branch rate is 85.7, the lateral fruiting plant rate is 88.9, and the average fruit set per fruiting branch is 1.6. Nuts are oblong in shape. The weight of a single fruit is 9.5-15.4 g, the shell surface is smooth, the sutures are flat, and it is not easy to crack. The kernels are very easy to extract, and the kernel yield rate is 61.2. The kernels are light in color, plump and have good yield performance. This variety is suitable for forest-grain intercropping and edge planting of mountain terraces. Nuts become smaller in thin soil, in arid areas and when there is too much fruit. The nuts are round in shape, with a flat base and a slightly pointed top, with a longitudinal diameter of 3.94 cm and a transverse diameter of 3.29 cm. The average nut weight of the Xiangling walnut variety is 12 grams. The shell surface is smooth and beautiful, light yellow, with narrow and flat sutures and tight integration. The shell thickness is 0.9 mm. For the Xiangling walnut variety, whole kernels are available. The kernels are plump and full, with a fragrant and non-astringent taste. The kernel yield of the Xiangling walnut variety is 65.4. The fat content of the kernel is 65.5, the protein content is 21.6, the crude fat is 65.8, the carbohydrate is 9.8, Vb1 0.5mg, Vb2 0.08mg. The kernel color is light yellow, the flavor is excellent, and there is no astringency. Xiangling walnut variety nuts are of high quality.

Variety name: Guanhe No. 1

Dried fruit weight: 15-18g

Skin thickness: 0.7-0.8mm

Male and female Attributes: Monoecious

Time of production: Fruits appear in the same year, three years of profit, five years of high yield

Variety source: Guanhe No. 1 is Zibo Guanhe Agricultural Development Co., Ltd. in 2004 After the introduction of "8518" for planting, bud changes on a single plant were discovered in 2006. In 2011, a thin-skinned and early-fruiting walnut variety was successfully bred! Variety name: Xinxin No. 2

Variety type: early-fruiting variety, late-maturing type Male and female type: male-first variety Source: Developed by Xinjiang Forestry Department and others in 1979 from Wuzong Khaqi, Yixilik Township, Xinhe County It was selected from the real trees in the village and further cultivated by the Xinjiang Academy of Forestry Sciences to form a variety. In 1989, it was identified and promoted by the Ministry of Forestry. In August 1990, it passed the national appraisal and was named a new walnut variety. High-yielding characteristics: Xinxin No. 2 is a high-yielding variety, with stable tree vigor after fruiting. The flowering plant rate of grafted seedlings in the second year is more than 40, the flowering plant rate in the third year is 80, and the flowering plant rate in the fourth year is 98. In Xinjiang, the yield per plant during the fruiting period is 15-20 kilograms, and the maximum yield per plant reaches 25 kilograms. , the specific output is related to management and geographical conditions.

Phenological period: The female flowering period is from late April to early April. The female flowers bloom about 10 days earlier, and there are secondary male flowers. The nuts mature in early September and the leaves fall in early November. In southwest China, buds sprout in early March, female flowers are in full bloom in late March, male flowers are in full bloom in early to mid-April, fruits mature in mid-August, and leaves fall in late October.

Stress resistance: relatively drought-resistant, disease-resistant, barren-resistant, and able to withstand cold temperatures of -25°C.

General comments: This variety has medium tree vigor, an open crown, strong adaptability and stress resistance, strong early yield, high yield in the fruiting period, excellent quality, and is suitable for dense planting cultivation. Xinxin No. 2 is an early-fruiting variety. In the first three years, the tree type should be mainly cultivated, and attention should be paid to picking flowers and fruits! Fruit should not be hung, otherwise it will affect the growth of the tree and affect later yields.
