Problems solved by technology

[0006] The technical problem to be solved by the present invention is: at present, the cuttings of Zhongshan fir mostly use traditional simple substrates such as sand, garden soil, plant ash and peat, and the pH value, EC value, and There are great differences in porosity, etc., and there is no clear standard for substrate parameters. Not only the physical and chemical properties of the substrate are poor, but also lack of nutrients, which leads to problems such as low survival rate of seedling cuttings and weak growth of cutting seedlings.

Embodiment 1

[0033] Embodiment 1 prepares the organic fermented material of Zhongshan fir cutting substrate:

[0034] Mix tea dregs (with a water content of 80%, waste tea dregs from tea beverage factories), hulled chaff and mushroom dregs at a ratio of dry matter mass ratio of 13:3:1, and adjust the content of the materials by strip-stack fermentation. After the amount of water is added, tank fermentation is carried out to make the material ferment evenly:

[0035] Bar stack fermentation (quick dehydration): Stack the mixed material in bar stacks (width 200cm, height 100-120cm, length depends on the situation) and press 0.3kg / m 3The amount of inoculated fermentation bacteria agent (organic material decomposing agent, produced by Nanjing Ningliang Biological Engineering Co., Ltd.). Dehydration, ventilation and loosening, the same operation below), strip-stack fermentation for about 5-7 days, when the moisture content of the material is adjusted to 55%-60%, the strip-stack fermentation is ...

Embodiment 3

[0041] Embodiment 3 prepares the organic fermented material of Zhongshan fir cutting substrate:

[0042] Mix tea dregs (with a water content of 80%, waste tea dregs from tea beverage factories), husk chaff and mushroom dregs at a ratio of dry matter mass ratio of 14:3:1. After the water content is reduced, tank fermentation is carried out to make the material ferment evenly:

[0043] Bar stack fermentation (quick dehydration): Stack the mixed material in bar stacks (width 200cm, height 100-120cm, length depends on the situation) and press 0.4kg / m 3 The amount of inoculated fermentation bacteria agent (organic material decomposing agent, produced by Nanjing Ningliang Biological Engineering Co., Ltd.). Dehydration, ventilation and loosening, the same operation below), strip-stack fermentation for about 5-7 days, when the moisture content of the material is adjusted to 55%-60%, the strip-stack fermentation is completed;

Abstract

The invention discloses an ascendens mucronatum cutting medium and a preparation method and application thereof. The ascendens mucronatum cutting medium comprises the following components in parts by mass:36-72 parts of organic fermentation materials, 2-6 parts of peat, 8-30 parts of vermiculite and 2-8 parts of perlite; the organic fermentation materials are obtained by mixing tea residues, rice husk and mushroom residues according to the dry matter mass ratio of (9-18):(1-5):(0.5-3) and then carrying out fermentation. The ascendens mucronatum cutting medium is rich in organic matters, humic acid and various nutrient substances, can realize the labor saving and cost saving during seedling culture, save the non-renewable resources, protect the ecological environment and realize the low-carbon circulation by substituting for the traditional cutting medium. According to the medium, a hole tray is adopted for cutting seedling culture, so that the slip cutting and rooting rate and the survival rate are remarkably increased, seedling are uniform and strong, root systems are prosperous and the integrated cost, namely labor cost and the like, of seedling culture and seedling lifting cost can be saved by 700-1000 yuan per mu compared with that of the conventional seedling culture production.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a Zhongshan fir cutting substrate and a preparation method and application thereof. Background technique [0002] Zhongshan fir is a semi-evergreen tall tree with a tall and straight trunk and a beautiful tree shape. It was selected and bred by the Nanjing Botanical Garden of the Chinese Academy of Sciences after years of experimental research. The trunk is straight, the tree shape is beautiful, the leaves are green for a long time, salt and alkali resistance, water and humidity resistance, strong wind resistance, less pests and diseases, and fast growth. It is suitable for river beaches with pH < 8.5 and coastal wetlands with a salt content < 2.0%. Growth has the characteristics of wide adaptability, strong wind resistance, less pests and diseases, emerald green leaves, dense branches and leaves, tall and straight trunks, beautiful tree shapes, rapid growth, excellen...
