Seed harvesting

The fruits of bamboo and cypress usually mature in November, but some bloom and bear fruit twice a year, and some mature in March. It is suitable to select 20-50-year-old bamboos and cypresses with good growth without diseases and pests for seed collection. When it is observed that the outer skin of bamboos and cypresses turns from green to yellow, they can be harvested. The collected fruits should be placed in a cool and ventilated place, and the post ripening can be completed in about 10-20 days. When the peel turns purple and the pulp is soft, wash the pulp and dry the seeds in the shade before sowing. Or adopt the method of sand accumulation. One layer of seeds is covered with one layer of sand. Each layer is generally about 10cm thick, and the total height should not exceed 1m. Seeds can be taken and sown in the next spring

Seeding and seedling raising

It is suitable to choose fertile sandy loam with short sunshine, convenient water source and good permeability as bed seedling. Make a deep ditch high bed, and open a ditch on the bed for on-demand sowing. The ditch distance is about 25cm, the ditch depth is 3cm, and the seed distance is generally about 5cm. 15kg seeds are usually used per mu

After sowing, it is necessary to build a shade shed with a transmittance of about 30% - 50%. At the same time, in the process of management, timely weed, loosen the soil and top dressing, drainage and irrigation. If the seedlings are 20-30cm high in that year, they can go out of the nursery for afforestation. If they are used as seedlings for street trees, it is best to stay in the nursery for more than 1-2 years

Management after sowing

After sowing in that year, it is necessary to do a good job in intercropping, weeding, topdressing and other work. In case of drought, it is necessary to water to cool down and cover the grass to preserve moisture. After that, it is necessary to carry out intercropping and weeding once or twice a year until the bamboo and cypress are closed into a forest or the height grows to more than 3 meters. In addition, bamboo and cypress need to be trimmed to maintain a good tree shape and improve its ornamental
