Example Embodiment

[0029] Embodiment 1: (Preparation 1 of the compound matrix of Qinggang container seedling raising)

[0030] The preparation of this compound matrix is ​​carried out according to the following steps:

[0031] (1) Carbonization of rice husks: Use bricks to surround a conical stove with an inner diameter of 150cm and a height of 80cm on the ground, leaving a gap of 1-2cm between the stove bricks, take an iron pipe with an inner diameter of about 10-12cm and place it obliquely In the stove, the high end rests on the brick edge on the upper part of the stove and sticks out of the stove wall, and the low end sticks out from the stove mouth and leans on the ground; first fill the stove with wood, and when the fire burns to the maximum, put a piece of The diameter is slightly larger than that of the stove, and an iron sheet evenly covered with holes of about 1.5 cm is placed on the stove; and then the dried rice husks discarded from local agricultural production are poured on the iron...

Example Embodiment

[0036] Embodiment 2: (Preparation 2 of the compound matrix of Qinggang container seedling raising)

[0037] The proportion of the prefabricated substrate in this example is: carbonized rice husk 29%, perlite 33%, peat 38%; the proportion of slow-release slightly soluble compound fertilizer is: commercially available slow-release nitrogen fertilizer and slightly soluble phosphorus, potassium and Iron and zinc micro-fertilizers, according to nutrient content N:P 2 O 5 :K 2 O:Fe:Zn=15:4:5:0.3:0.2, the specific slow-release and slightly soluble compound fertilizer can be composed of 722g of urea-formaldehyde nitrogen, 145g of diammonium phosphate, 200g of potassium sulfate, 25g of ammonium iron phosphate and 21g of zinc carbonate ; The ratio of compound matrix is: slow-release compound fertilizer and prefabricated matrix are 2.5kg: 1m 3 The proportions are mixed; the preparation technology and method are the same as those in Example 1.

Example Embodiment

[0038] Embodiment 3: (Preparation 3 of compound matrix of Qinggang container seedling raising)

[0039] The proportion of prefabricated substrate in this example is: carbonized rice husk 35%, perlite 27%, peat 38%; the proportion of slow-release slightly soluble compound fertilizer is: commercially available slow-release nitrogen fertilizer and slightly soluble phosphate fertilizer, potassium fertilizer and Iron and zinc micro-fertilizers, according to nutrient content N:P 2 O 5 :K 2 O:Fe:Zn=14:5:3:0.35:0.1, the specific slow-release and slightly soluble compound fertilizer can be composed of urea-formaldehyde nitrogen 672g, monoammonium phosphate 184g, potassium sulfate 120g, ammonium iron phosphate 29g and zinc carbonate 11g ; The ratio of the compound matrix is ​​that the slow-release compound fertilizer and the prefabricated matrix are 3kg: 1m 3 The proportions are mixed; the preparation technology and method are the same as those in Example 1.

Abstract

The invention discloses a compounded medium for Cyclobalanopsis glauca container seedlings, which belongs to the technical field of forest seedling cultivation. The medium can be prepared through the following steps: carbonized rice husks, perlite and peat are mixed into a preformed medium according to the volume ratio of 25 to 35:25 to 35:35 to 50; according to that the mixture ratio of nutrient content of N:P2O5:K2O:Fe:Zn is 14 to 16:3 to 5:3 to 5:0.2 to 0.35:0.1 to 0.25, slow-release nitrogen fertilizer, slightly soluble phosphate fertilizer, potassium fertilizer, iron, zinc trace fertilizer which are sold in markets are made into a slow-release slightly soluble compounded fertilizer; and then the fertilizer and the preformed medium are made into the compounded medium in the proportion of 2 to 3 kg:1m<3>. The medium has the advantages that the medium is simple and reasonable in formulation, stable in quality, convenient to get materials, low in cost, lower in peat consumption, sufficient in fertility, long in fertilizer effect, capable of meeting the demand of Cyclobalanopsis glauca seedlings for nutrients, 23 to 33 percent lower than the prior medium formulation in prices and high in cost performance, and can be popularized and applied in the production of Cyclobalanopsis glauca container seedlings.

Description

technical field [0001] The invention relates to the technical field of forest tree seedling cultivation, in particular to a compound substrate for container seedling cultivation of Qinggang. Background technique [0002] Cyclobalanopsis glauca is an evergreen broad-leaved tree species of Fagaceae. It is one of the main tree species in the humid evergreen broad-leaved forest belt in the subtropical east of my country. Tannin can be extracted, the wood is strong and rot-resistant, and the seed kernel can be extracted for starch consumption. It is the main tree species in water conservation forests and soil and water conservation forests. [0003] For a long time, green hills have been afforestation using la-grown field bare-root seedlings. The seedlings are taller, the tap roots are longer, and the fibrous roots are few. When the seedlings are raised, the roots and leaves are easily damaged, which directly affects the survival rate of afforestation and the growth of young fores...
