Brief introduction of planting big hazelnut tree
Corylus heterophylla likes sunny environment. Maintaining it in the sunny place can promote its growth, development and fruiting. It can grow on sandy soil, loam, clay and light saline-alkali soil, and is suitable for growing in low-altitude terrain. It is often distributed in the land below 750 meters above sea level in the north of China.
Corylus heterophylla is widely distributed in China. It is planted all over the country except Xinjiang, Fujian, Taiwan Province, Guangdong and Guangxi, with the largest planting scale in the three northeastern provinces and the best planting in spring and autumn. The common varieties are Corylus heterophylla, Corylus davidiana, Corylus spinosa and Corylus yunnanensis.
The fruit of big hazel tree planted for several years.
Corylus heterophylla generally begins to bear fruit after 3-4 years. Corylus heterophylla has strong adaptability to soil, but it is best to plant it on loose, fertile sandy loam with good drainage. The soil layer is more than 50 cm thick and has strong adaptability to soil acid and alkali soil, and it can grow and bear fruit normally in the range of pH 5.5-8.0.
Grafted hazelnut trees blossom and bear fruit.
Generally, the grafted hazelnut can blossom and bear fruit in about 2 years, but the initial number of fruits is relatively small, and the life span of its clusters can usually reach more than 50 years. The yield of hazelnut trees will increase exponentially with the growth of tree age from fruiting to the fifth year of planting, and it can continue to grow and bear fruit for 30 to 50 years.
Why doesn't the big hazel tree bear fruit?
The reason why the big hazelnut tree doesn't bear fruit may be that the time is not up, so it can bear fruit after waiting patiently for a period of time. In addition, if it doesn't provide suitable fertilizer, water, temperature and light during the growth period, it will also affect the fruit, and it will affect pollination when it meets rainy or low-temperature weather during the flowering period.
Key points of planting hazelnut tree
Because the male flowers of Corylus heterophylla bloom earlier than the female flowers, when the stamens are open but there is no loose pollen, the inflorescence should be picked, and then collected and put in a bottle when the pollen is scattered, and then the pistil is opened and lit on it.
There should be sufficient nutrients in the development of Corylus heterophylla, whether during flowering, fruiting or fruit expansion, which can reduce flower and fruit drop, supplement the nutrients needed for fruit growth, protect flowers and fruits, and improve fruit expansion. During this period, urea and fertilizers containing potassium are mainly applied.
