Embodiment 1

[0023] Embodiment 1: A kind of substrate formula of hickory nut container seedling cultivation, comprising peat soil, perlite and yellow heart soil. The volume ratio of peat soil, perlite and yellow core soil is 3:1:1. The yellow heart soil is the yellow heart soil that is 30-50cm deep from the surface. The sand content of yellow heart soil is 30-50%.

[0024] In this embodiment, the sprouts are transplanted into the matrix, and the yellow heart soil component contained in the matrix can prevent the seeds of the sprouts transplanted into the matrix from rotting and deteriorating and affecting seedling growth. At the same time, the yellow heart soil can reduce the incidence of pests and diseases during the growth of sprouts. The yellow core soil 30-50 meters deep from the surface is used to provide the necessary sand content for transplanting sprouts. At the same time, the yellow core soil has the functions of water and fertilizer retention through the yellow core soil with ...

Embodiment 2

[0027] Embodiment 2: a kind of preparation method of the substrate of hickory nut container seedling cultivation, comprises the following steps:

[0028] 1) Preparation of matrix raw materials, adding yellow heart soil into a pulverizer and pulverizing into fine particles. The purchased perlite is screened and subdivided through a leaky sieve to obtain perlite raw materials suitable for plant transplanting substrates. Remove the purchased peat moss and send the peat moss into a container for later use.

[0029] 2) Mix the matrix raw materials, mix the peat soil, perlite and yellow core soil in the matrix raw materials prepared in step 1) according to the volume ratio of 3:1:1, and mix the peat soil, perlite and yellow core soil by stirring Uniform, prepared as a matrix.

[0030]In this embodiment, the yellow heart soil is added into a pulverizer and crushed into fine particles, which facilitates the mixing of the yellow heart soil and other components in the matrix. The pur...

Embodiment 3

[0031] Embodiment 3: a kind of application method of the substrate of hickory nut container seedling cultivation, comprises the following steps:

[0032] A. Fill the matrix, fill the prepared matrix into the container bag, and the distance between the top surface of the matrix and the opening edge at the top of the container bag is 3-5cm.

[0033] B, transplanting of seedlings, root-cutting of unearthed sprouts after vernalization, main root retaining 2-6cm, and transplanting of sprouts into container bags filled with matrix, and the depth of planting is the depth of just exposing seeds. The substrate is compacted, and the sprouts are compacted. Then, water it slowly once.

[0034] C. Post-management, according to the specified time interval cycle, water the container bag to ensure that the soil is moist. Regular hand weeding of seedlings growing in container bags. Then according to the season months, the seedlings growing in the container bag are poured with fertilizer, an...

Abstract

The invention discloses a substrate formula of thin-shell hickory container seedling cultivation and a preparation method and application thereof, and relates to the technical field of cultivation. According to the technical scheme, the substrate formula comprises peat soil, perlite and yellow core soil, wherein a volume ratio of the peat soil to the perlite to the yellow core soil is 3: 1: 1; theyellow core soil is the yellow core soil with a depth of 30-50cm from a ground surface; a sand content of the yellow core soil is 30-50%; the preparation method of the substrate comprises the following steps of: 1) preparing substrate raw material; 2) mixing the substrate raw material, mixing evenly the peat soil, perlite and yellow core soil in the substrate raw material prepared in 1) accordingto the volume ratio of 3: 1: 1 to prepare the substrate; and the application of the substrate comprises: A substrate loading; B seedling transplanting; and C post management. The substrate formula ofthe thin-shell hickory container seedling cultivation and the preparation method and application thereof have the advantages that a transplanting survival rate of sprouts and a grafting rate of rootstocks are obviously improved, a seedling cultivation period is shortened, and a fibrous root system of seedling roots formed by seedling cultivation is developed.

Description

technical field [0001] The invention relates to the field of cultivation technology, more specifically, it relates to a substrate formula and a seedling raising method for container seedling cultivation of thin-shell hickory nuts. Background technique [0002] Thin-shelled hickory, also known as American hickory, is a species of Juglandaceae and Hickory. Native to the United States and Mexico, it is one of the most important oil-bearing dried fruit tree species in the world. Its shell is thin and easy to peel, its kernels are thick and fleshy, and it has a delicious taste and high nutritional value. The trunk is straight, the tree shape is beautiful, the roots are deep and the leaves are luxuriant, and it is an excellent tree species for greening and gardening around. At the same time, the wood is tough and dense, with dark red heartwood, yellow-white sapwood, high elasticity, and is not easy to deform and crack. It is an excellent timber tree species for construction and h...
