Problems solved by technology

In recent years, the provenance source of Dalbergia japonica introduced and planted in Pingtan County is relatively chaotic, and some Hainan Dalbergia ( D. hainanesis ) tree species are also introduced as Dalbergia dalbergia, and some have poor growth, many side branches, and inconspicuous main stems due to different provenances, which bring great losses to production.
The second is that the management is relatively extensive, and most of the planters have low cultivation technology content. Some forest farmers and professional afforestation households are eager to let Dalbergia dalbergia grow fast. While topdressing a large amount of fertilizer, excessive pruning promotes the high growth of the tree, resulting in weak tree stems. Weakness, without the support of cables and anchors, it will fall here and there, and the growth and development will be uncoordinated. Diameter shape is extremely unfavorable

Embodiment 1

[0026] A kind of cultivation method of large-diameter material Dalbergia japonica, comprising the steps:

[0027] Step 1, base fertilizer application before planting. Aiming at the problems such as many branches of the main stem and bent branches in the growth of Dalbergia Dalbergia, a new method of management and fertilization for Dalbergia Dalbergia seedlings was invented, that is, before the Dalbergia Dalbergia seedlings are planted Dig and plant a 60×60×60cm planting hole. When planting trees, dig a hole to loosen the soil and use 20 kg of organic fertilizer for backup (the hole surface is 30cm higher than the ground pad when planting in front of the house and behind the house), every ten days from June to September in the first year Dissolve 0.15 kg of compound fertilizer in 1000 g of water and apply it 20 cm away from the saplings after 12 hours.

[0028] Step 2, after planting, set a fixed cable above the Dalbergia japonica sapling to fix its tree pole and guide its gro...

Embodiment 2

[0038] A kind of cultivation method of large-diameter material Dalbergia japonica, comprising the steps:

[0039] A. Aiming at the problems such as many forks of the main pole in the soft and curved growth of Dalbergia japonica, a new method of cultivation and fertilization of young Dalbergia japonica seedlings was newly invented. Before transplanting the Dalbergia japonica seedlings, planting holes were dug in the wild mountainous areas and in front of and behind houses 80 × 80 × 80cm, when planting trees and digging holes to loosen the soil, use 20 kg of organic fertilizer and loosen the soil to mix evenly for later use. Consider plant ash and weeds with a thickness of 20-30cm at the bottom of the hole in the dry season.

[0040] B. The height of Dalbergia Dalbergia tree is 3 meters, and the side branches of the lower part cannot exceed 1.5 meters in length. The survival rate of Dalbergia Dalbergia seedlings is 98%. The forest will be formed in the next year, reducing the co...

Abstract

The invention relates to the field of nursery stock planting, and particularly relates to a method for cultivating large timber dalbergia odorifera. The method comprises the following steps: digging planting holes before dalbergia odorifera seedlings are planted, putting plant ash and weeds at the bottom of the planting holes, and planting; setting fixed cables above the dalbergia odorifera seedlings to fix trunks and guide growth of the seedlings; obliquely inserting a tripod into the ground on the side face of the dalbergia odorifera seedlings after the diameter at breast height of the dalbergia odorifera seedlings are more than 10cm, and the seedling height is more than 8m, adding a brick at the tube foot, and fixing the dalbergia odorifera trunks with the tripod. The method has the beneficial effects that mixture of plant ash and weeds is put at the bottom of the planting holes to avoid water shortage of seedlings in dry season; the fixed cables are matched with cable anchors and other supports to fix the trunks of dalbergia odorifera to achieve the effects of reinforcing and preventing dalbergia odorifera breakage caused by typhoon damage; and the effect of positioning and guiding growth of dalbergia odorifera.

Description

technical field [0001] The invention relates to the field of planting seedlings, in particular to a method for cultivating large-diameter wood Dalbergia japonica. Background technique [0002] Dalbergia ( Dalbergia odorifera T.Chen), also known as Hainan Huanghua pear, rosewood, etc., belongs to the leguminous plant Papilionaceae Dalbergia genus, and is a rare tree species unique to Hainan. It is listed as a national second-class protected plant and is a national standard 5. It belongs to one of 33 species in 8 categories. Its material texture is staggered, its structure is dense, it is hard and heavy, its pattern is beautiful after finishing, its luster is oily, it has a fragrant smell, it will never crack or deform after drying, it is extremely resistant to corrosion, humidity and salt. Alkali is not resistant to frost, so it is the first-class material for making expensive furniture, exquisitely carved handicrafts and garden greening. At present, most of the tree speci...
