Embodiment 1

[0019] The first step of preparation before raising seedlings: choose loamy soil with fertile soil, thick soil layer, good irrigation and drainage. Before the seedlings are planted, apply fertilizer and then deep plow and ditch. The ditch distance is 60cm, the ditch width is 25cm, and the depth is 20cm. Spread fertilizer in the ditch, mix the soil and fertilizer evenly, and water heavily.

[0020] Step 2 Selection of seedlings: Select seedlings with a well-developed root system, 2 lateral roots with a diameter of 0.4 cm and a length of 15 cm, no pest damage and mechanical damage, a root neck diameter of 0.5 cm, and a seedling height of 90 cm.

[0021] The third step is planting of seedlings: the seedlings are planted obliquely along the ditch in the ditch, and the planted seedlings are at an angle of 20° to the ground. The distance between plants is based on the length of the seedlings, preferably 10 cm between the roots and shoots of adjacent seedlings. After planting, firm ...

Embodiment 2

[0025] The first step of preparation before raising seedlings: choose loamy soil with fertile soil, thick soil layer, good irrigation and drainage. Before the seedlings are planted, apply fertilizer and then deep plow and ditch. The ditch distance is 90cm, the ditch width is 35cm, and the depth is 35cm. Spread fertilizer in the ditch, mix the soil and fertilizer evenly, and water heavily.

[0026] Step 2 Selection of seedlings: Select seedlings with complete and well-developed root system, 6 lateral roots with a diameter of 1.0 cm and a length of 30 cm, no pest damage and mechanical damage, a root neck diameter of 1.2 cm, and a seedling height of 110 cm.

[0027] The third step is planting of seedlings: the seedlings are planted obliquely along the ditch in the ditch, and the planted seedlings are at an angle of 30° to the ground. The distance between plants is based on the length of the seedlings, preferably 15 cm between the roots and shoots of adjacent seedlings. After pla...

Embodiment 3

[0031] The first step of preparation before raising seedlings: choose sandy loam soil with fertile soil, thick soil layer, good irrigation and drainage. Before the seedlings are planted, sprinkle fertilizer and then dig deep and open a ditch. The ditch distance is 75cm, the ditch width is 30cm, and the depth is 28cm. , spread fertilizer in the ditch, mix the soil and fertilizer evenly, and water heavily.

[0032] Step 2 Selection of seedlings: Select seedlings with a well-developed root system, 3 lateral roots with a diameter of 0.5 cm and a length of 25 cm, no pest damage and mechanical damage, a root neck diameter of 0.8 cm, and a seedling height of 100 cm.

[0033] The third step is planting of seedlings: the seedlings are planted obliquely along the ditch in the ditch, and the planted seedlings are at an angle of 25° to the ground. The distance between plants is based on the length of the seedlings, preferably 12cm between the roots and shoots of adjacent seedlings. After...

Abstract

The invention relates to a layering propagation method for Folium Isatidis used as a rootstock of large cherry, belonging to the technical field of plant propagation. The method comprises the following five steps: preparation before seedling raising, seedling selection, seedling planting, seedling thinning, and soil covering and layering. The invention also further optimizes data involved in the above-mentioned steps. The Folium Isatidis seedlings obtained by using the method provided by the invention have the following advantage: the survival rate of transplanting is high and can reach 85% or more.

Description

technical field [0001] The invention relates to a layering propagation method, in particular to a method for propagation of a large cherry rootstock, Folium chinensis, and belongs to the technical field of plant propagation. Background technique [0002] Daqingye, which is used as a rootstock of big cherry, has the advantages of wide and dark green leaves, well-developed root system, more vertical roots, not easy to lodging, strong cold resistance, and high resistance to root nodule. The large cherries grafted with it as a rootstock have a high survival rate and rarely have "little feet". The young trees grow robustly and have high and stable yields during the full fruit period. It is one of the excellent rootstocks for large cherries. Layering propagation is its main propagation method, but Folium folium cuttings are not easy to take root, and the current layering propagation technology has a low emergence rate, which is far from meeting the needs of the market.
