Embodiment 1

[0043] Example 1 A method for cutting seedlings of the lignified middle branches of upright column fruit trees (compared with cutting seedlings of young branches)

[0044] The cutting operation of upright column fruit trees was carried out in late April in the glass mesh room of the Institute of Tropical Forestry, Chinese Academy of Forestry.

[0045] (1) Preparation of ear seedlings: select a healthy and straight-trunked wild upright columnar fruit tree (8.6 cm in diameter at breast height, 8.0 m in height), and remove the lignified branches with an end diameter of 1.6 cm as the source of cutting material;

[0046] (2) Preparation of mixed substrate and selection of container: Mix the volume percentage of peat soil 70% + perlite 25% + vermiculite 5% to obtain a mixed substrate; then put the mixed substrate into the cutting container, 2 days before cutting The matrix is ​​sprayed and disinfected with a potassium permanganate solution of 0.5% by mass, subject to the soaked matr...

Embodiment 2

[0051] The cutting operation of upright column fruit trees was carried out in the first ten days of September in the glass mesh room of the Institute of Tropical Forestry, Chinese Academy of Forestry.

[0052] (1) Preparation of ear seedlings: select a healthy and straight-trunk wild upright column fruit tree (diameter at breast height of 10 cm, tree height 8.5m), and take off lignified branches with a diameter of 1.2 cm as the source of cuttings material;

[0053] (2) Preparation of mixed substrate and selection of container: fully mix peat soil 65% + perlite 30% + vermiculite 5% to obtain a mixed substrate; then put the mixed substrate into the cutting container, and use the mass percentage 2 days before cutting Use 0.5% potassium permanganate solution to spray and disinfect the substrate, subject to the mixed substrate being drenched, the cutting container adopts a 50-hole seedling tray with a length of 540 mm, a width of 280 mm, and a depth of 500 mm;

[0054] (3) Preparat...

Embodiment 3

[0058] The cutting operation of upright column fruit trees is carried out in April, and the place is the glass mesh room of the Institute of Tropical Forestry, Chinese Academy of Forestry.

[0059] (1) Preparation of ear seedlings: select a healthy and straight-trunk wild upright column fruit tree (diameter at breast height of 8 cm, tree height 6.7m), and take off lignified branches with an end diameter of 1.8 cm as the source of cuttings material;

[0060] (2) Preparation of mixed substrate and selection of container: fully mix peat soil 74% + perlite 22% + vermiculite 4% to obtain a mixed substrate; then put the mixed substrate into the cutting container, and use the mass percentage 2 days before cutting 0.5% potassium permanganate solution is used to disinfect the substrate by sprinkling irrigation, and the mixed substrate shall be drenched as the criterion. The cutting container shall be a 50-hole seedling tray with a length of 540 mm, a width of 280 mm, and a depth of 500 ...

Abstract

The invention discloses a cutting seedling-raising method of a lignified middle branch of conocarpus erectus, and belongs to the technical field of vegetative propagation. The cutting seedling-raising method comprises the following steps: selecting healthy conocarpus erectus with straight trunk as a seed tree; cutting 8-15cm branches from a part 6-60cm away from the top end of the lignified branch as a cutting; soaking the cutting in water; disinfecting; soaking the lower part of the cutting through a plant growth regulating agent treating solution; then inserting into a mixed substrate to cultivate. With the adoption of the method for raising seedlings, the technical bottleneck that the branches of conocarpus erectus are hard to root due to high tannin content can be broken; the lignified middle branches of conocarpus erectus start to root 30 to 35 days after the cutting and inserting and can be transplanted after 4 to 5 months, so that the rooting time can be effectively reduced, the cottage rooting rate and transplanting survival rate can be obviously improved, and the cottage rooting quality is high; the method can maintain the good properties of the lignified middle branch of conocarpus erectus, is stable and reliable, beneficial for popularization, and has a good development prospect.

Description

technical field [0001] The invention belongs to the technical field of plant vegetative propagation, and in particular relates to a method for growing seedlings by cuttings of lignified middle branches of upright fruit trees. Background technique [0002] Upright columnar fruit trees ( Conocarpus erectus (L.)), for the Conocarpus tree species of Combretaceae, an evergreen tree. [0003] The upright column fruit tree is naturally distributed in America. It has a straight tree shape, a beautiful crown, and a moderate height (6-10 m). It can not only grow in tidal flats, but also settle on land to beautify the environment. Malaria, mainly for malaria), there are more plantations in Florida, Mexico, and the Gulf of California, Mexico, and are more cold-resistant. Especially on the trailing edge of Florida coastal beaches, there are neat and single upright cylindrica forests, which are mainly used as windbreak and wave dissipation forest belts to resist the attack of typhoon s...
