Embodiment 1

[0013] Choose farmland with hillsides and good drainage, and the groundwater level is less than 80 cm. Fertilize the site in winter, apply basal fertilizer per mu to the field, including: 800-1200 kg of chicken manure, 80-120 kg of compound fertilizer, or 300-500 kg of decomposed cake fertilizer and 100-200 kg of compound fertilizer. Use an excavator to fully reclaim and plow the land to a depth of 60 cm, clean up the root piles, and dig the drainage ditches around and in the center. Plant and cultivate 1-2 year old magnolia magnolia grafted seedlings. When the grafted seedlings rise, the diameter of the soil ball is 10 times the diameter of the rhizosphere of the grafted seedlings, and they are tied with straw ropes to prevent the soil ball from being broken during transportation. The planting distance is 1.8m~ 2.5m, with a row spacing of 1.0m to 1.8m. After 2 to 3 years, the plant should be transplanted at intervals from late March to early April. When transplanting Magnolia...

[0016] Choose farmland with hillsides and good drainage, and the groundwater level is less than 80 cm. Fertilize the site in winter, use an excavator to open a planting ditch with a width of 60-100 cm and a depth of 60 cm, place the topsoil and core soil on both sides of the planting ditch, and spread 10-15 cm thick at the bottom of the planting ditch Fill the top soil into the ditch 20 cm after freezing and felling, and then apply the base fertilizer. The base fertilizer per mu includes: 800-1200 kg of chicken manure, 80-120 kg of compound fertilizer, or 300-500 kg of decomposed cake fertilizer. kg, 100-200 kg of compound fertilizer.

Abstract

The invention discloses a fast-growing cultivation method for Magnolia grandiflora Linn, belonging to the field of tree cultivation. The method comprises the following steps of: digging a farmland for 60cm deep to prepare the land in winter, conducting permanent planting cultivation to 1-year-old to 2-year-old Magnolia grandiflora Linn grafted seedlings, conducting spaced-plant transplanting within the last ten days of March to the beginning of April after two to three years, conducting pruning in spring and summer within three years after transplanting, keeping the height of a crown to be one third of the height of a tree, ensuring that a trunk does not have crotches at a position below 1.6m to 2.0m, pinching and removing unwanted sprouts in time and focusing on cultivating the trunk. By conducting scientific and effective cultivation management to the Magnolia grandiflora Linn through field planting, transplanting, water manure management, shaping and pruning, the survival rate of the grafted seedlings at an early stage can be well ensured, the development of the root systems of the grafted seedlings and the growth of the trunks are promoted at the same time and the growth speed and the seedling quality of the Magnolia grandiflora Linn are further improved through pruning. By adopting the method, the diameter of the cross-section of the tree trunk of the Magnolia grandiflora Linn can grow 2cm to 3cm every year and can grow to 12cm to 15cm when the Magnolia grandiflora Linn is 5-year to 6-year old.

Description

technical field [0001] The invention relates to a method for cultivating forest trees, in particular to a method for cultivating Magnolia magnolia. Background technique [0002] Magnolia grandiflora (scientific name: magnolia grandiflora linn) belongs to Magnoliaceae, also known as lotus magnolia and foreign magnolia. It is native to America and is a large evergreen tree with a height of 20-30m. Bark light brown or gray, cracked in thin scales. Magnolia magnolia grows light-loving and is slightly shade-tolerant when young. It likes a warm and humid climate and has a certain ability to resist cold. It has strong resistance to smoke and sulfur dioxide gas, and has few pests and diseases. Deep root system, strong wind resistance. Especially the sowing seedlings have tall and straight trunks, majestic trees and strong adaptability. Magnolia magnolia is an elegant tree, evergreen in all seasons, and has few pests and diseases. Therefore, it is an excellent street tree specie...
