Embodiment 1

[0034] Embodiment 1, the preparation of modified sodium lignosulfonate

[0035] S1 Dissolve sodium lignosulfonate in water to prepare an aqueous solution of sodium lignosulfonate with a mass percent concentration of 35%, heat it to 95°C, keep the temperature at a constant temperature for 35 minutes, then add propylenediamine, the amount of propylenediamine added is lignin 50% of the total volume of the sodium sulfonate aqueous solution, then dropwise add glutaraldehyde, the addition of the glutaraldehyde is 85% of the total volume of propylenediamine, and react at a temperature of 80°C for 2h to obtain modified lignosulfonic acid sodium solution;

[0036] S2 extracts the modified sodium lignosulfonate solution obtained in step S1 with absolute ethanol to obtain an extract, washes the extract with petroleum ether, and freeze-dries after washing. The freeze-drying conditions are:- Pre-freeze at 6°C for 2 hours, then freeze at -18°C for 18 hours at a vacuum of 0.06mPa to obtain ...

Embodiment 2

[0037] Embodiment 2, nutrient soil of the present invention

[0038] Described nutrient soil is made up of following composition and parts by weight thereof:

[0039] 35 parts of sea mud, 8 parts of peat soil, 20 parts of activated sludge, 18 parts of plant ash, 8 parts of sodium alginate, 4 parts of loosening agent, 4 parts of phoxim, 8 parts of potassium dihydrogen phosphate and 10 parts of calcium chloride; The sludge sedimentation ratio of the activated sludge is 18-22%, the sludge volume index is 90-95ml / g, and the dissolved oxygen in the effluent of the secondary sedimentation tank is 1.2-1.8mg / L; the loosening agent is composed of tripolyphosphoric acid Sodium and modified sodium lignosulfonate are composed in a mass ratio of 4:3; the modified sodium lignosulfonate is the modified sodium lignosulfonate prepared in Example 1.

[0040] The above-mentioned sea mud, peat soil, activated sludge, plant ash and loosening agent are first mixed uniformly, then sodium alginate, ...

Embodiment 3

[0041] Embodiment 3, nutrient soil of the present invention

[0042] Described nutrient soil is made up of following composition and parts by weight thereof:

[0043] 40 parts of sea mud, 10 parts of peat soil, 25 parts of activated sludge, 22 parts of plant ash, 8 parts of sodium alginate, 6 parts of loosening agent, 5 parts of phoxim, 9 parts of potassium dihydrogen phosphate and 12 parts of calcium chloride; The sludge sedimentation ratio of the activated sludge is 18-22%, the sludge volume index is 90-95ml / g, and the dissolved oxygen in the effluent of the secondary sedimentation tank is 1.2-1.8mg / L; the loosening agent is composed of tripolyphosphoric acid Sodium and modified sodium lignosulfonate are composed in a mass ratio of 5:2; the modified sodium lignosulfonate is the modified sodium lignosulfonate prepared in Example 1.

[0044] The above-mentioned sea mud, peat soil, activated sludge, plant ash and loosening agent are first mixed uniformly, then sodium alginate,...

Abstract

The invention belongs to the technical field of plant cultivation, and particularly relates to a cultivation method for improving the survival rate of big bruguiear gymnorrhiza seedling transplanting.The cultivation method for improving the survival rate of big bruguiear gymnorrhiza seedling transplanting comprises the steps that mature bruguiear gymnorrhiza hypocotyl is placed in home-made nutrient soil andcultured into young seedlings, and the young seedlings are transplanted into a seedbed and cultured into the big seedlings, after root-cutting treatment, the big seedlings are subjected tobag cultivation for a time, and then the big seedlings can be transported and transplanted for afforestation. The plant height of a young bruguiear gymnorrhiza tree cultured by using the cultivationmethod for improving the survival rate of big bruguiear gymnorrhiza seedling transplanting is 1.6-1.8 m, the crown breadth reaches 50-80 cm, the survival rate of transplanting reaches 96% or above, the salt tolerance is good, planting and afforestation can be conducted on mudflat or hard beaches, the functions of shore protection, wave dissipating, disaster reduction and resisting, coastal environment optimization, biological diversity maintenance of bruguiear gymnorrhiza can be given full play to.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a cultivation method for improving the survival rate of transplanting large seedlings of oleracea. Background technique [0002] Mangroves are woody plant communities that grow in the intertidal zone of tropical and subtropical coasts and are periodically inundated by seawater. They have unique morphological structures and functional adaptability, such as forming pillar roots and various forms of respiratory roots. There are many Viviparous seedlings and xerophytic structure and salt-resistant adaptation. Mulan is the main arbor mangrove plant in the coast of South China. It usually grows from the upper part of the middle beach to the inner beach. Its well-developed root system can not only make the plant stand firmly on the beach, but also use the respiratory roots to absorb oxygen in the air and improve the water quality. Oxygen can be accommodated, there...
