Seed selection
When planting palm trees, it is advisable to choose plants that are more than 15 years old, grow robust, develop normally, dry and straight, and have no pests and diseases as the mother tree. The fruit of the palm tree is generally mature in December. When the peel changes from yellow-green to yellow-brown, the seed can be harvested. After the fruit is harvested, it must be fully dried, and the fruit pods are chopped to remove the edge of the pod to obtain the seed. The flower seed of the flower is generally about 70%. On average, there are 3,550 to 4,500 seeds per kilogram. Flower palm seed can not be placed for a long time, it is best to follow the seeding, otherwise it will affect the emergence rate and germination rate.
Seedling cultivation
The seedbed should be leveled before sowing, and the seedbed should be sprayed with potassium permanganate or thiophanate for disinfection.
Pear seeds are easy to germinate. Soak seeds in water for 24 hours before sowing. After drying out, spread the seeds evenly on the bed surface, then cover the soil with a thickness of about 1cm, then cover with a layer of thin grass, or use a shade net to shade the shed. After the seeds are sown, they should be drenched in the morning and evening. Keep the bed wetting properly and germination for about half a month. The germination rate of fresh and full seeds is over 90%.
Seedling transplant
When the cotyledons of the flowering seedlings turn green and the true leaves begin to grow (about 20 to 30 days after the seeds are germinated). It can be transplanted into a nutrition bag.
Seedling management
About half a month after the seedling transplant, the urea can be applied thinly. Maintain sufficient water and nutrients, usually pay attention to the prevention and control of seedling pests and diseases. It is mainly to spray thiophanate or chlorothalonil every 7 to 10 days to prevent disease. If properly managed, the 1-year seedling diameter can reach 1.5 to 2.0 cm. When the seedling height is 50-60cm, the low-cut dry seedlings are used for afforestation.
Afforestation technology
Afforestation land selection: Afforestation can be carried out on barren hills and semi-sun slopes of barren hills and wasteland below 600m above sea level. Site preparation: land preparation in the winter before the afforestation, so that the soil is fully weathered. At the same time, some pests are eliminated. It is best to take a mountain refining operation. If the slope of the mountain is more than 20°, the horizontal belt should be opened, and the afforestation should be acupuncture. The specification is 50cm×50cm×40cm. Afforestation with nutrient cups. Not only the survival rate, but also the preservation rate is high (90% PA).
Cultivation density: The plant spacing is determined by the site conditions, 3m×3m in the water and fertilizer conditions, and 3m×2m or 2m×2m in the arid areas. Should be the base of the base fertilizer. Each point can be applied 2.5 ~ 5 kg of farmyard manure and more than 2509 nitrogen, phosphorus and potassium fertilizer mixed.
Cultivation Techniques
The afforestation season is best chosen in March and April. At the latest, it should not be more than June. It should be planted after light rain or rain. The seedlings stop fertilizing and reduce the number of watering 10 days before going up the mountain, and classify and spray the seedlings to prevent pests and diseases. Carefully tear the film bag off, straighten, and compact when planting.
Tending management
After the afforestation, the seedlings were small and easily inhibited by weeds. Tending or not is the key to success or failure in afforestation. After two months of cultivation, weeding should be carried out once in a timely manner, and weeding and loosening the soil once the weed seeds mature in autumn.
You have to raise twice in the following year. Complete removal of weeds, loose soil, expansion and topdressing. 1 time before and after the rainy season, combined with tending to fertilize 1 time before the rainy season (100-200 grams of compound fertilizer per plant to promote the growth of trees, promote its early canopy.
The flowering palm tree has lower branches and thick side branches. When tasting, it is necessary to pay attention to plastic pruning and cultivate excellent dry shape. The flower palm wood is easy to fall, and the tending management should also be inserted into the bamboo seedlings next to the seedlings to promote the vertical growth of the trunk and form excellent dry materials.
