Aksu, with the reputation of "hometown of walnuts", as early as in the "History of the Museum" in the Jin Dynasty, there is a record of "Zhang Yu's Western Region, but also the walnut species."

Aksu walnut quality technical requirements (a) variety. "Warm 185", "New 2", "Zha 343". (2) Site conditions. The cultivated soil, sandy loam soil and aeolian sandy soil with higher fertility and lighter texture in the protected area are selected as the cultivated soil. The thickness of the soil layer is more than 1.5 meters, the pH value is between 7.0 and 7.8, and the total salt content is less than 0.2%. Below 2 meters, the surface organic matter content is ≥1%. No pollution, there are irrigation conditions. (3) Cultivation techniques. 1. Seedlings: Choose grafted seedlings of “Xinxin 2”, “Wen 185” and “Zha 343”. 2. Planting density: Depending on the soil condition and variety traits, ≤44 plants per 667m2 (mu). 3. Fertilization: The main fertilizer is ≥2500kg/667m2 (mu). 4. Plastic trimming: comprehensively use the methods of sparse, cut, pick and pull, so that the branches inside the canopy are even, ensuring sufficient illumination and good ventilation. Shu Xiong, planted in the current year and the second year of the plant, all female and male flowers are sparse. The result tree strips out 3/4 or 2/3 male flowers, reduces nutrient consumption, promotes fruit setting, and increases yield. 5. Environmental and safety requirements: The use of pesticides, fertilizers, etc. must comply with relevant national regulations and must not pollute the environment. (4) Harvesting. 1. Harvesting time: The green peel turns from green to yellow, and the whole tree 2/3 green fruit is naturally cracked. The green peel is easy to be harvested when it is peeled off. 2. Post-harvest treatment: After removing the green skin by hand, rinse with damp water, then dry the washed nuts for 5d to 7d (sunny day). When the nut touches the sound, the sound is crisp and the diaphragm is easy to be chopped. Milky white can be light yellowish brown. Chemicals are strictly prohibited during peeling. (5) Quality characteristics. 1. Sensory features: (1) "Warm 185": the nut is round or oblong, the fruit base is round, the fruit top is tapered, the shell surface is smooth, the suture is flat or slightly protruding, and the combination is tight, easy to take the whole kernel, core The kernel is full and full, milky yellow and fragrant. (2) "Xinxin No. 2": the nut is oblong, the fruit base is round, the fruit top is slightly smaller, flat or slightly round, the shell surface is smooth, light yellowish brown, the suture is flat, the combination is tight, the kernel is yellowish brown, easy Take the kernel, the seeds are full and the flavor is fragrant. (3) "Zha 343": the nut is oval or oval, the shell surface is light brown, smooth and beautiful, the suture is flat, the combination is tight, the color is yellowish brown, easy to take the kernel, the kernel is full and the flavor is fragrant. 2. Physical and chemical indicators: the project index Wen 185 new new No. 2 343 average fruit weight, g ≥ 12 ≥ 10 ≥ 13 out of the rate, (%) ≥ 55 ≥ 43 ≥ 45 uniformity, (%) ≥ 90 ≥ 90 ≥ 90 fruit rate, (%) ≤ 4 ≤ 4 ≤ 4 shell fruit rate, (%) ≤ 3 ≤ 3 ≤ 3 broken fruit rate, (%) ≤ 0.3 ≤ 0.3 ≤ 0.3 water content, (%) ≤ 6.5 ≤ 6.5 ≤ 6.5 shell thickness, (mm) ≤ 0.8 ≤ 1.2 ≤ 1.23. Safety requirements: product safety indicators must meet the relevant provisions of the state for similar products
