Abstract
The invention discloses a substrate for culturing pecans and a method for preparing the same. The substrate comprises edible fungus residue, loess and urea. Water accounts for 50-60% of the total mass of the substrate. The method for preparing the substrate comprises mixing the edible fungus residue and the loess according to the volume ratio of (2-4):1, adding the urea accounting for 0.5% of the mass of the substrate by mass percentage and evenly mixing the mixture; adding carbendazim or potassium permanganate solution, maintaining that water accounts for 50-60% of the total mass of the substrate; and then covering the substrate with a film for 7-10 d. A whole set of small container seedling culture system for the pecans is provided; formula ingredients of the substrate are simple, the substrate is convenient to prepare and low in cost, a certain amount of slow-release fertilizer is added to provide nutrient for seedling growth at a later period; the practice proves that the height of seedlings cultured by the substrate and the ground diameter growth amount are higher than those of a control group, and the survival rate of the seedlings is also greatly improved. In addition, the pecans are deep-root trees, main roots are robust, the pecans grow rapidly, and the size of a seeding culture container can meet the root growth of annual pecan seedling roots.
Description
Technical field
The present invention relates to forestry field of planting, relate in particular to a kind of pecan tree culture medium and preparation method thereof.
Background technology
Pecan tree (
carya illinoinensiskoch), have another name called apocarya, pecan, belonging to Juglandaceae hickory, is the Eco-economic Type seeds integrating high-grade dry fruit, afforestation, high-grade timber.Pecan tree introduces China's history of existing more than 110 year; but so far; do not form industrialization yet to produce; one of wherein main technical reason is that the breeding technology of nursery stock is broken through at all; growing-seedling period is long; reproductive efficiency is low, is difficult to form large-scale production, seriously limits the Industry Promotion that apocarya is produced.
The cultivation of current domestic pecan tree seedling mostly adopts traditional field seeding seedling raising manners (bare-root seeding), and because these seeds have deep-rootedness, the bare-root seeding side root of incubation is few, and seedling quality is poor, and transplanting survival rate is low, and transplanting seedling time is long.Container nursery can overcome the above-mentioned shortcoming of bare-root seeding, have that growing-seedling period shortens, unit surface produce seedling amount high, save the area and use the advantages such as kind.Compare with Jian Yuan with exposed root and shoot forestation, container seedling have high, the slow seedling of transplanting survival rate, characteristics and advantages that Afforestation Time can extend or change.The trend having expansion is cultivated in China's container nursery in recent years, but the preliminary stage that the science that is also in generally is produced, lack container for plant growth type, substrate formula and cultivate container seedling technical study.
Summary of the invention
Goal of the invention: the object of this invention is to provide pecan tree culture medium that a kind of composition is simple, easy to prepare, seedling replanting surviving rate is high and preparation method thereof.
Technical scheme: in order to realize foregoing invention object, a kind of pecan tree culture medium of the present invention, comprise edible mushrooms residue, loess and urea, in matrix, water accounts for 50 ~ 60% of total mass.
Described edible mushrooms residue comprises straw rotting fungus class residue or wood rotting fungi residue, to comprise in bisporous mushroom, Coprinus comatus, straw mushroom, mushroom, needle mushroom, Grifola frondosa, flat mushroom, Hypsizygus marmoreus the combination of any one or multiple residue.
Wherein, needle mushroom, flat mushroom, Hypsizygus marmoreus are wooden rotten class fungi, containing trace elements such as higher iron, calcium, zinc and magnesium, are more suitable for as pecan tree culture medium.
The volume ratio of described edible mushrooms residue and loess is 2 ~ 4:1.As preferred version of the present invention, the volume ratio of described edible mushrooms residue and loess is 3:1.Add a certain amount of loess in seedling medium, matrix Water-saving effect can be improved, and not easily loose.Edible mushrooms residue is a kind of stable long-acting fertilizer, and source is wide, is of high nutritive value.
Described urea accounts for 0.5% of matrix gross weight by mass percentage.
A kind of preparation method of pecan tree culture medium comprises the steps:
(1) by the edible mushrooms residue of volume ratio 2 ~ 4:1 and loess mixing, the urea adding total matrix mass percent 0.5% mixes;
(2) add derosal 500 ~ 800 times of liquid or mass content is the potassium permanganate solution of 0.05%, keep water in matrix to account for 50 ~ 60% of total mass;
(3) step (2) gained material is mixed, plastic film covering 7 ~ 10 d.
The nutrition pot that above-mentioned small vessels seedling medium is used, be uncovered cylindrical structural, wherein, diameter is 15cm, and height is 26cm.The NM technology of the present invention is prior art.
beneficial effect:the present invention is directed to a complete set of culture system that pecan tree proposes small vessels nursery, the system component of matrix is simple, easy to prepare, with low cost, adding a certain amount of long-acting fertilizer for later stage seedling growth provides nutrient, facts have proved that the height of seedling and height growth that utilize this matrix to cultivate are all higher than control group, seedling is also improved greatly in surviving rate.In addition, pecan tree is deep-rootedness seeds, and main root is flourishing and growth is rapid, and the size of container for plant growth can meet the growth of annual pecan tree seedlings root.
