Potted podocarpus macrophyllus nutrient soil and preparation method thereof

Abstract

The invention relates to the technical field of podocarpus macrophyllus planting, in particular to potted podocarpus macrophyllus nutrient soil and a preparation method thereof. The nutrient soil is prepared from, by weight, 100-150 parts of fertile topsoil, 15-35 parts of humus soil, 10-40 parts of plant ash, 5-25 parts of pine sawdust, 3-15 parts of pine wood shavings, 1-10 parts of river sand,3-8 parts of pine park with particles being smaller than or equal to 1 cm, 4-16 parts of bentonite, 2-15 parts of vermiculite, 7-21 parts of humic dried cow dung, 1-10 parts of humic dried chicken manure, 1-9 parts of humic dried pigeon dung, 0.1-3 parts of 50% carbendazim wettable powder, 1-5 parts of azotobacter, 0-3 parts of bacillus subtilis, 1-8 parts of earthworm powder, 0.1-5 parts of borax, 1-8 parts of calcium superphosphate, 1-9 parts of plant acid salt and 1-5 parts of softener; the nutrient soil is prepared through the five processes of partial raw material dry mixing, wet freezing, high-pressure stirring, residual raw material mixing and wet sterilization. The processed nutrient soil can effectively prolong the soil energy supply cycle, the average growth vigour of podocarpusmacrophyllus is improved, soil porosity can be kept for a long time, and soil hardening is prevented.

Description

technical field [0001] The invention relates to the technical field of Podocarpus pine planting, in particular to nutrient soil for Podocarpus pine potting and a preparation method thereof. Background technique [0002] Podocarpus, alias Tushan, Podocarpus family, Podocarpus is an evergreen coniferous tree, up to 20 meters, diameter at breast height of 60 cm; bark gray or taupe, shallow longitudinal fissures, falling off in thin flakes; branches spread or slant , denser. Leaves spirally inserted, strip-lanceolate, slightly curved. Male cones are spicate and axillary, with several triangular bracts at the base; female cones are solitary in leaf axils, stalked, with a few bracts at the base. Seeds ovoid, round at apex, fleshy aril purple-black with white powder when ripe, seed receptacle fleshy cylindrical, red or purple-red. The flowering period is from April to May, and the seeds mature from August to September. [0003] Distributed in many provinces and regions in China...

Problems solved by technology

However, when potting Podocarpus pine, due to the limited volume of the pot, the amount of soil in the pot is effective, and the limited soil cannot provide sufficient nutrients for the long-term growth of Podocarpus pine, or the nutrients contained in the soil are absorbed by Podocarpus pine in a short time or automatically dissipate, resulting in too much or too little Podocarpus nutrient absorption
