Hezhang walnut is named after it was produced in Hezhang County, Guizhou Province. Because Hezhang County has a high altitude, long light, and large temperature difference. The highest altitude is 2900.6 meters (the highest point in Guizhou). The unique microclimate is especially suitable for the growth of walnuts. Therefore, although the Hezhang walnut is not big, its appearance is thin, the kernel is full, the kernel is full, the kernel is easy to take, and the flavor is delicious. Pure and other characteristics, is one of the export of agricultural special products.

"Hezhang walnut" is a geographical indication protection product. Because Hezhang County has a high altitude, long light, and large temperature difference. The highest altitude is 2900.6 meters (the highest point in Guizhou). The unique microclimate is especially suitable for the growth of walnuts. Therefore, although the Hezhang walnut is not big, its appearance is thin, the kernel is full, the kernel is full, the kernel is easy to take, and the flavor is delicious. Pure and other characteristics, is one of the export of agricultural special products. Hezhang walnut is abundant in Hezhang County, Bijie Prefecture, Guizhou Province, China. The county has a long history of walnut cultivation and is the distribution center of iron walnut in southern China. There are many native walnut germplasm resources in the territory. After years of screening and cultivation, it has formed wild wild treasures. Hezhang walnut seedlings are not afraid of dryness and are afraid of flooding. If it is planted on the ground, it is necessary to do a good job of dredging and dredging. Do not let the land accumulate water. Walnuts are happy. After entering the result period, more light conditions are needed. More than 5 hours, can ensure the normal growth and development of walnuts. When planting seedlings, the choice of garden, planting density, cultivation methods and plastic trimming must all consider the problem of daylighting. Hezhang walnut seedlings have strong adaptability. In rural areas, walnut trees are called “lazy trees”. Its management is very simple, and the work that needs to be done every year is not cumbersome. Three times a year, fertilization and chemical weeding, plus some Necessary pruning and shaping. Any walnut has no effect on altitude and temperature. For example, Lhasa, Xinjiang, Gansu, and more than 6,000 meters above sea level, can grow normally under minus 30 degrees, while Xinjiang walnut is very famous and has high yield, such as Hainan walnut in the tropics. Growth is normal. In 2006, Hezhang County was selected by the State Forestry Administration as the “National Walnut Forestry Standardization Construction Demonstration Zone”. The pollution-free and green walnut nuts produced in the demonstration area have more unsaturated fatty acid content and amino acid content than the average walnut content. On this basis, walnut sugar, walnut dew, walnut dishes, etc. have been developed, which has increased the added value of walnuts and brought rich benefits to local growers. In 2007, the walnuts selected by Hezhang County Forestry Bureau were selected as “Olympic Recommended Fruits” by 8 units including China Fruit Distribution Association. In June 2008, Hezhang County was awarded the honorary title of “Hometown of Chinese Walnuts” by China Fruit Distribution Association. .

Hezhang walnut quality technical requirements First, the source of iron walnut (Juglans sigllata Dode). Second, the site conditions The altitude of the production area is 1700 to 1900 meters, the soil types are mainly mountain shrub meadow soil, mountain yellow brown soil, yellow soil purple soil, lime soil. The soil pH is 6.2 to 7.5, the soil organic matter content is ≥3%, and the soil layer thickness is ≥1 m. Third, planting management Seedling: Take the walnut seedlings as the rootstock and graft and breed. 2. 41 strains / 667 m2 (mu). 3. Fertilization: After harvesting in autumn, combined with soil, the base fertilizer is applied, and each plant applies 100 to 150 kg of organic fertilizer and 3 to 5 kg of calcium, magnesium and phosphate fertilizer. When the saplings were planted, the saplings began to topdress after germination, once a month until August; in the second to fourth years, three times of fertilizer were applied in March, June and August; the adult trees were topdressed twice, the time was before germination. And fruit hard core period (6 to July). Before germination, the pig manure water per 667m2 (mu) is ≥1000kg, urea is ≥20kg; the fruit in the hard core period is ≥2000kg per 667m2 (mu), urea ≥30kg, potassium sulfate ≥20kg, superphosphate ≥20kg . 4. Plastic pruning: the combination of summer pruning and winter pruning, and winter pruning after the fruit is harvested and the leaves turn yellow before being cut off. The tree shape is mainly composed of sparsely dispersed and natural happy. 5. Fresh fruit harvest: Green fruit turns from green to yellow-green, and the skin of 2/3 or more fruits naturally cracks or falls off, which is the best harvesting period. 6. Pest Control: The common pests and diseases are mainly the cloud spotted beetles, and the prevention and control measures are based on the principle of “prevention first, comprehensive prevention”. In June, artificially catching adult insects, and timely use the drug to plug the insect holes, licking dead eggs and larvae, sprayed 40% of the insecticide net 500 times in August, the prevention rate can reach more than 90%. 7. Environmental and safety requirements: The use of pesticides, fertilizers, etc. must comply with relevant national regulations and must not pollute the environment. Fourth, processing De-greening: Can not peel off on the day of harvesting, peeling off in time after stacking. 2. Five, quality characteristics Sensory features: nuts nearly round or oval, fruit base round, fruit tip, shell surface slightly hemp, yellowish white or light amber; sutures narrow and convex, tightly combined; full, light white or light yellow, Easy to take whole kernels, pure flavor. 2. 3. Safety and other quality technical requirements: Product safety and other quality technical requirements must comply with relevant national regulations.
