Description

Cultivation method for increasing planting survival rate of tabebuia avellanedae in yellow soil hills

Technical Field

The invention relates to a method for cultivating tabebuia avellanedae. In particular to a cultivation method for improving the planting survival rate of tabebuia avellanedae in yellow soil hills.

Background

The yellow soil hills in the south China are barren, have medium soil viscosity and are poor in air permeability. The tabebuia avellanedae is a new domesticated variety introduced in China in recent years, and has yellow flower color, cluster inflorescence and bright color. However, most of the planting of the tabebuia flavedo is in the field, which is not in accordance with the national policy of farmland protection. The sycamore is planted in the yellow soil hills in south China, the root system grows badly, the survival rate is low, and the quality of planting in the same batch is uneven.

The existing planting technology of the tabebuia avellanedae in the yellow soil hilly land comprises the following steps: selecting tabebuia avellanedae with a breast diameter of 4-5 in 1-4 months, cutting a stem at a position of 2m, digging up a soil ball of the 20 tibetan seedlings, digging a tree hole in a yellow soil hilly land, placing the soil ball of the tree in the tree hole, backfilling the tree hole with original soil, and digging fixed-root water to fill the soil ball.

The prior planting technology has the defects that: 1. the trunk is cut into the rod without leaves. The plant loses the ability of synthesizing auxin by terminal buds, loses the advantage effect of the terminal buds and influences the germination and growth of root systems. 2. The soil ball before planting is not sterilized and root-promoted, and the germination and growth of a small part of viable root systems carried by the soil ball are completely depended, so that the root systems grow slowly. 3. The original soil is used for backfilling, the soil is barren, the soil is heavy in viscosity, after the rooting water is beaten, the soil is easy to be pulped and hardened, the soil ball is poor in air permeability, and the root system growth is not facilitated. 4. The secondary transplantation needs to dig earth again, causes destruction to hills soil layer structure, is taken place soil erosion and water loss easily by the rain wash. 5. The cultivation is limited to 1-4 months.

Disclosure of Invention

The invention aims to provide a cultivation method for improving the planting survival rate of tabebuia avellanedae in yellow soil hills.

The technical scheme for realizing the invention is as follows: a cultivation method for improving the planting survival rate of tabebuia avellanedae in yellow soil hills comprises the following steps:

(1) And (3) sterilizing the root system of the seedling: removing the original soil of the soil ball of the seedling, reserving the root system, and disinfecting the root system of the seedling;

(2) Planting in a planting bag: filling part of the matrix at the bottom of the planting bag, putting the disinfected nursery stock into the planting bag, and continuously filling the matrix until the matrix is 5cm away from the bag opening; wherein the matrix consists of decomposed herbal traditional Chinese medicine residues and dry farmyard manure;

(3) Transplanting: transplanting to the planting point after the root system of the seedling is stable.

In the step (1), selecting the seedlings from the tabebuia avellanedae with the diameter at breast height of 4-6cm, keeping the top tips, trimming most annual branches and leaves, and keeping branches over 2 years. The soil ball is dug with the diameter of 30cm and the thickness of 25cm. The soil ball is dug with the diameter of 30cm and the thickness of 25cm.

In the step (1), the mixed solution of hymexazol and rooting agent is used for disinfecting the root system of the nursery stock. Specifically, 300 mg of 32% hymexazol and 60 g of 40% rooting agent are mixed and added with 30L of water, and the root system of the seedling is put into the solution to be soaked for 5 minutes.

In the step (2), the mass ratio of the decomposed herbal traditional Chinese medicine residues to the dry farmyard manure in the matrix is 80: 20.

In the step (2), the substrate is filled to the bottom of the tree planting bag with the thickness of 20cm, then the planted nursery stocks are placed into the planting bag, the substrate is filled by a water flow stamping method when the planting bag is filled with the substrate with the thickness of 10cm, the root system and the substrate are fully combined, and no empty drum is left.

In the step (2), 1mm of micro-sprinkling irrigation is additionally arranged on each tree, and under the condition of high temperature, the micro-sprinkling irrigation is started for 5 minutes in the morning and 2 minutes in the afternoon, so that the trunk is wet during the daytime in sunny days, and the soil ball is wet and does not run. The sprinkling irrigation method lasts for 2 months. In non-high temperature weather, irrigation is carried out according to the principle that 'no dry and no irrigation, and irrigation is thorough'.

In the step (2), the nursery stock is supported and fixed by a bamboo pole with the length of 1.5m and the diameter of 3cm by a triangular supporting method.

And (3) arranging the planting points on hills, planning according to the row spacing of 2 x 2m, and leveling the planting points, wherein the leveling area of each planting point is 0.5 square meter.

Compared with the prior art, the invention has the following beneficial effects:

1. by using the planting technology, the survival rate of the tabebuia avellanedae is improved to more than 95%, and the growth uniformity is excellent.

2. Before planting, the root system of the seedling is disinfected and promoted to grow, and the root system is promoted to germinate and grow.

3. The decomposed herbal traditional Chinese medicine residues and the dry farmyard manure are used for forming the matrix, the plant roots are more stable, concentrated root packing is more uniform through cultivation of the tree planting bag, and the subsequent transplanting survival is stable.

4. The planting bag is used as a container for cultivation, secondary digging and damage to a root system are avoided, transplanting is convenient, and the survival rate of the subsequent engineering seedlings is improved.

5. The invention can cultivate the lilac tabebuia in 1-6 months and 10-12 months in south China. The cultivation time is longer than that of the traditional planting technology. And the cultivated tree forms can be standardized more easily through management.
