Pentagonal maple tree tall, beautiful tree, excellent material, autumn leaves are very beautiful, excellent viewing and timber species. The main points of its seedling technology are as follows:
Seed breeding mothers must be strong, strong and high-quality plants. From September to October, the seeds of the Pentagonal Maple tree grow from green to yellow-brown. After the seeds are sunned for 2 to 3 days, the bag is hidden after being mixed.
Soil preparation sites for bed nurseries should be lands with flat terrain, convenient irrigation and drainage, deep soil layers, and fertile soil. Saline-alkali land and ponds should not be used as nurseries. During site preparation, apply fertilizer 3000 to 5000kg of fertilizer or soil miscellaneous fertilizer per mu, cake fertilizer 100kg, urea or diammonium 40kg, and build a flat bed.
Sowing more than sowing in the spring. Before sowing, soak in seeds with warm water at 50°C for 10 minutes, then add cold water to soak for a day and night, remove the seeds and put it in a pouch, place it in a leeward place, rinse it once with warm water once a day, and stir evenly until 50% of the seeds break. You can sow. When drilling, the spacing is 20~30cm, sowing depth is 2cm, sowing 15~20kg per acre and covering earth 1.5~2cm. Cover grass after sowing to keep the soil moist.
The seed can be germinated and unearthed after 15 to 20 days after sowing. The grass should be removed. When the seedling height is 10cm, it needs time and seedlings, and the seedling height is 10~15cm. After Dingmiao, every 10 to 15 days of irrigation, fertilization 1 times, each time the application of fertilizer per acre 5 ~ 8kg or excrement 500 ~ 750kg. Timely cultivating, weeding, pest control. In September, nitrogen fertilization and irrigation were stopped to promote the lignification of seedlings and increase their ability to withstand cold in winter. When the seedling height was about 1m, the seedlings could be transplanted and cultivated for greening purposes.
