Planting time: Walnut is one of the most widely distributed economic tree species in China, and it is most suitable for planting in spring and autumn. It is cultivated in spring after soil thawing and before germination, and in autumn after beginning of autumn and before ground freezing, from beginning of autumn 10 to mid-April of the following year.

Distribution: Walnuts are widely distributed in China, including Liaoning, Tianjin, Beijing, Hebei, Shandong, Shanxi, Shaanxi, Ningxia, Qinghai, Gansu, Xinjiang, Henan, Anhui, Jiangsu, Hubei, Hunan, Guangxi, Sichuan, Guizhou, Yunnan and Tibet.

Growth cycle of walnut tree

Walnuts germinate in March, pollinate in April, bear fruit in May, accumulate oil in June, July and August, and harvest in September. It takes half a year to germinate mature fruits. Young walnut trees grow vigorously within 1-2 years after planting.

Cost and profit of planting walnut trees

The price of walnuts is relatively high. The fruit price of Carya cathayensis is higher than that of 40 yuan, and the grafted seedlings are higher than that of 30 yuan. In recent years, the yield of walnut is still very low. If you can't plant it well for five years, you'd better not plant walnuts.

The profit of planting walnut trees is about 3000 yuan per mu. If properly managed, the yield of walnut trees in full fruit stage is about 500-600 kg, the wholesale price of thin-shell walnut is about 10 yuan/kg, the income per mu is about 5000-6000 yuan, the investment per mu is about 2000 yuan, and the net profit is about 3000 yuan.

Key points of walnut tree planting technology

Fertilization: After walnut planting, if the demand for fertilizer is not great in July and August, low-nitrogen compound fertilizer can be used appropriately according to the tree potential, especially without additional nitrogen fertilizer, otherwise the flower bud differentiation will be insufficient, which will affect the next year's results.
