Seedling raising by cutting method of taxodium 'Zhongshansha' in green house containers, and substrates

Abstract

The invention discloses a seedling raising by cutting method of taxodium 'Zhongshansha' in green house containers. The seedling raising by cutting method comprises the steps of preparing seedbeds, performing cutting and performing management after cutting. The invention also discloses substrates for seedling raising by cutting of taxodium 'Zhongshansha' in green house containers. The substrates consist of the following components of 76-84% of turf, 7-9% of perlite, 5-7% of carbonized rice chaff, 3-5% of vermiculite and 1-3% of controlled-release fertilizers. A high bed cultivation mode is combined with adjustment of components of the substrates, control of temperature and humidity during the seedling raising period is guaranteed, and the substrates consisting of the turf, the perlite, thecarbonized rice chaff, the vermiculite and the controlled-release fertilizers are combined for use, so that the survival rate can be greatly increased, cutting seedlings of the same year can be sold in the same year to generate economic benefits and can be completely sold before plum rain season the next year, production of next batch of cutting seedlings of the taxodium 'Zhongshansha' in glass green houses is not influenced, transformation and upgrading of a conventional seedling raising manner of forestry seedlings to high-quality development are realized, and a high-efficient development mode of being short, stable and fast, of the forest seedling industry can be realized.

Description

technical field [0001] The invention relates to a Zhongshan fir seedling raising method and a substrate, in particular to a Zhongshan fir greenhouse container cutting seedling raising method and a substrate, belonging to the technical field of plant asexual propagation. Background technique [0002] At present, Zhongshan fir has been listed as the preferred tree species for coastal afforestation. It is planted all over the country, and its market prospect is very promising. Most of the seedling cultivation of Zhongshan fir in the prior art is carried out on the ground using open-air sunshade net steel frame facilities and ordinary plastic film greenhouse facilities combined with flat ground. The conditions are relatively simple, the survival rate of cuttings is only about 20%, and the commodity rate is only 50% to 60%. %, leading to poor production efficiency, failing to achieve the expected goal of stable production and increasing efficiency, unable to effectively respond t...

Problems solved by technology

Most of the seedling cultivation of Zhongshan fir in the prior art is carried out on the ground using open-air sunshade net steel frame facilities and ordinary plastic film greenhouse facilities combined with flat ground. The conditions are relatively simple, the survival rate of cuttings is only about 20%, and the commodity rate is only 50% to 60%. %, leading to poor production efficiency, failing to achieve the expected goal of stable production and increasing efficiency, unable to effectively respond to market order production, and greater market risk

At the same time, the substrate soil used by most Zhongshan fir cultivation manufacturers on the market is general-purpose substrate soil, which cannot meet the needs of Zhongshan fir seedling cultivation, resulting in defects such as low survival rate and slow growth of seedlings, and cannot adapt to the current Zhongshan fir cultivation.
