Hunan 26cm diameter tree transplanting Luan, Luan tree skeleton 30 cm, 35 cm entire Koelreuteria

Hunan 26cm diameter tree transplanting Luan, Luan tree skeleton 30 cm, 35 cm entire tree management Luan Luan tree plantation management (1) shade: shade time, shade should be considered at the time of the local temperature and weather conditions, and to ensure its seedlings for the degree of harm from sunburn. To be gradually extended into the fall photoperiod and light intensity, until accept full light, in order to improve the degree of woody seedlings. (2) thinning, fill the gaps: the seedlings grow to 5 ~ 10cm high, to be thinning, with spacing of 10 to 15cm thinning combined with water after applying fertilizer, Liumiao about 12 per square meter. Between thinning requirements of small to stay big, stay superior to inferior, between dense stay thin, all seedlings equidistant and rainy days as well. Combined with thinning, carried on Quezhu Bumiao treatment to ensure seedling distribution. (3) the daily management: Always tillage, weeding, watering, keep the bed moist, late fall after the leaves most of the seedlings can be up to 2m, coarse diameter of about 2cm. The rise seedling grading, second transplant in the spring, before the transplant will slightly cut some roots, truncated after the transplant seedling roots stem from the place, from the surface of the stubble, then irrigated. After germination should always Maya, leaving only the strongest buds develop into the trunk. Growing often loose soil, weeding, watering, fertilizer, to fall straight through the trunk can develop. (4) Migration: shoots transplanting seedlings can promote root development, seedlings a year high 50 ~ 70cm. Koelreuteria deep-rooted trees, should be repeated to form a good and effective transplant roots. Seedlings in the year after the leaves fall into the ditch heel to rise, planted next spring equinox. Luan Luan tree tree trunk is not easy because of the long straight, the first transplantation should cut dry stubble, and to strengthen the management of fertilizer. Spring sprout from the base of the branch, choose to stay straight, robust person trained to the trunk, the trunk growing fast, straight. The first cut stem mainly the second year in the spring can be re-cut dry processing. After the transplant once every three years or so, when transplanted to the appropriate cut taproot and lateral coarse to trigger new roots. Luan tree saplings grow slowly, twice before transplantation should be appropriately high density, helping to train straight trunk, saving land. After that should be appropriately sparse, culture intact canopy. (5) Fertilization: Fertilization is an important measure of nurturing seedlings. After seedling root length, should be combined with watering fertilization. In year growth period, should be subject to the nitrogen-based fertilizer quick result, promote vegetative growth of plants. Autumn, to stop nitrogen, increasing phosphorus, potassium, in order to improve the degree of woody plants to improve cold tolerance of seedlings. Winter, farm organic fertilizer should be applied as basal provides both holding effect of nutrients, but also played insulation, soil improvement role of seedling growth. With the growth of seedlings, to gradually increase the amount of fertilizer to meet the demand for nutrients seedling growth. The first volume should be less fertilizer per acre of nitrogen fertilizer 2500g to 3000g, separated 15 days after a fertilizer, fertilizer may be slightly larger.
