Taxodium Zhongshanha cutting medium and seedling raising method thereof

Abstract

The invention belongs to the technical field of agriculture, and discloses a taxodium Zhongshanha cutting medium and a seedling raising method thereof. The taxodium Zhongshanha cutting medium is prepared by mixing and fermenting taxodium waste, pine waste and loess according to the mass ratio of (2-5): (3-6): 2, and then adding with perlite. The method specifically comprises the following steps: S1, taxodium waste, pine waste, loess and perlite are collected; S2, the taxodium waste, the pine waste and loess are mixed according to the mass ratio of (2-5): (3-6): 2 and subjected to stack retting, and the mixture is rotted; S3, unrotten sundries in the S2 are picked out, and humus soil of taxodium and pine is obtained; S4, the humus soil and perlite are evenly mixed according to the volume ratio of 8: 2, and the taxodium Zhongshanha cutting medium is obtained; and S5, the medium in the step S4 is placed into a container bag for later use. According to the technical scheme, different preparation methods are adopted for the taxodium Zhongshanha cutting medium, so that the seedling culture process is simplified, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a Zhongshan fir cutting substrate and a seedling raising method thereof. Background technique [0002] Zhongshan fir is an excellent interspecific hybrid of three tree species native to North American bald genus, bald cypress, pool fir and Mexican bald cypress. Its trunk is straight, the tree shape is beautiful, it has the characteristics of long green period of leaves, salt and alkali resistance, water and humidity resistance, strong wind resistance, less pests and diseases, and fast growth rate. Zhongshan fir is a semi-evergreen tall tree, and its roots often grow strange knee roots in humid environments. Zhongshan fir can grow in water for a long time, which can effectively remove total nitrogen and alkaline phosphorus in water, and can also effectively remove heavy metal elements in soil , to restore the soil. [0003] Because the mature seeds of Zhongshan fir do not ...

AI Technical Summary

Problems solved by technology

[0003] Because the mature seeds of Zhongshan fir do not germinate, asexual reproduction has to be adopted. At present, the cutting propagation of Zhongshan fir in China mostly uses the substrate to be made into ridges, and then the cuttings are inserted on these substrates. Most of the substrates are peat soil, river sand, and pearls. The mixture of rocks, so the production cost of the substrate is relatively high, and it needs to be transplanted many times when rooting and cultivating large seedlings, the seedling cultivation process is cumbersome and the production cost is high
