Embodiment 1

[0021] See Table 1 for the pH, organic matter content and nitrogen, phosphorus and potassium content of the seedling substrate of Example 1.

Embodiment 2

[0023] A seedling raising substrate is prepared by mixing the following components by weight: 35% of peat soil, 25% of perlite, 5% of vermiculite, 10% of sand, 10% of deep glue soil and 15% of waste fungus sticks. ;

[0024] Among them, the waste bacteria sticks have been sterilized and fertilized by centralized composting in advance. The specific operations are as follows: put the waste bacteria sticks into the composting tank, where the stacking thickness of the waste bacteria sticks is 100cm, and then spread a Layer carbon ammonia, the amount of carbon ammonia (that is, the amount of spreading) is 3kg / ㎡ (calculated by the area of ​​the treatment tank), and then covered with plastic film and sealed for 6 months;

[0025] Mix the above components uniformly in proportion, and then press 2kg / m 3 The proportion of slow-release fertilizer is added, and the seedling substrate is obtained by further mixing evenly.

[0026] The pH, organic matter content and nitrogen, phosphorus a...

Abstract

The invention relates to the technical field of seedling raising, and specifically relates to a seedling-raising substrate for nursery stock. The seedling-raising substrate provided by the invention aims to overcome the disadvantages of poor air permeability, deficient nutrients, and poor fertilizer and moisture retention abilities of seedling-raising substrates in the prior art. The substrate is prepared from the following components by weight: 30 to 40% of peat soil, 15 to 25% of perlite, 5 to 25% of vermiculite, 10 to 15% of sand, 10 to 15% of deep-seated puddle clay and 15 to 45% of waste mushroom-sticks. The substrate provided by the invention has rational formula and adequate nutrients; and the added sand can significantly improve permeability of the substrate and meet the need for oxygen needed by breath of a root system of a raised seedling, so that the roots of the raised seedling are insusceptible to rot, and the survival rate of the raised seedling is greatly improved.

Description

technical field [0001] The invention relates to the technical field of seedling raising, in particular to a seedling raising substrate for seedlings. Background technique [0002] The substrate is one of the important components of cultivating seedlings. It can enable broad-leaved tree seedlings to grow under root control conditions, provide sufficient nutrients, make seedlings grow rapidly, and improve seedling raising speed. [0003] Most of the existing seedling matrices at home and abroad are humus, that is, the mixture of litter and soil. This kind of matrices cannot be used for root-controlling seedlings, because there are many bacteria and air permeability, which is easy to cause the root system of seedlings to rot. , resulting in low survival rate of seedlings. In addition, the lack of nutrients in conventional seedling substrates makes the growth of seedlings relatively slow. [0004] Chinese patent CN102106248A, dated August 8, 2012, discloses a soilless cultivati...
