Embodiment 1

[0018] 1. Select new branches that grow robustly and uniformly, cut the base flat, remove the lower leaves, leave 2 leaves on the upper part, and cut branches with a length of 7 cm; the new branches have no forks and side buds.

[0019] 2. Dip the cuttings obtained in step 1 for 3S in the mixed solution of NAA and IBA, the concentration of NAA in the mixed solution is 300mg / L, and the concentration of IBA is 100mg / L.

[0020] 3. Insert the cuttings obtained in step 2 into a nutrient bowl filled with a matrix, pour water once, keep the temperature at 20°C, and keep the humidity at 70%, and then manage it as usual. The matrix is ​​peat, vermiculite and sand. The mass ratio is 1:1:1 mixed.

Embodiment 2

[0022] 1. Select new branches that grow robustly and uniformly, cut the base flat, remove the lower leaves, leave 3 leaves on the upper part, and the length of the cuttings is 8 cm; the new branches have 1 axillary bud.

[0023] 2. Dip the cuttings obtained in step 1 for 4S in the mixed solution of NAA and IBA, the concentration of NAA in the mixed solution is 350mg / L, and the concentration of IBA is 150mg / L.

[0024] 3. Insert the cuttings obtained in step 2 into a nutrient bowl filled with a matrix, pour water once, keep the temperature at 23°C, and keep the humidity at 80%, and then manage it as usual. The matrix is ​​peat, vermiculite and sand. The mass ratio is 1:1:2 for mixing.

Embodiment 3

[0026] 1. Select a vigorous and uniform new branch, cut the base flat, remove the lower leaves, leave 3 leaves on the top, and the length of the cutting is 9 cm; the new branch has 2 axillary buds.

[0027] 2. Dip the cuttings obtained in step 1 for 5S in the mixed solution of NAA and IBA, the concentration of NAA in the mixed solution is 400mg / L, and the concentration of IBA is 200mg / L.

[0028] 3. Insert the cuttings obtained in step 2 into a nutrient bowl filled with a matrix, pour water once, keep the temperature at 25°C, and keep the humidity at 90%, and then manage it as usual. The matrix is ​​peat, vermiculite and sand. The mass ratio is 1:1:3 for mixing.

Abstract

The invention discloses a method for prompting petunia cuttage rooting. The method includes the following steps: step 1, selecting a new branch which grows robustly and uniformly, cutting a base to be flat, removing leaves on the lower portion, reserving 2-3 leaves on the upper portion, and making a cutting of 7-9cm in length; step 2, dipping the cutting obtained in the step 1 in a mixed solution of NAA and IBA for 3-5S, wherein concentration of NAA in the mixed solution is 300-400mg / L, and concentration of IBA in the mixed solution is 100-200mg / L; step 3, inserting the cutting obtained in the step 2 in a nutrition bowl containing a matrix, watering sufficiently for one time, maintaining temperature at 20-25 DEG C and humidity at 70-90%, and managing according to common practice, wherein the matrix is formed by mixing peat, vermiculite and sand according to a mass ratio of 1:1:1-3. The method is simple, convenient in operation, low in cost, short in period and suitable for large-scale popularization.

Description

technical field [0001] The invention relates to the technical field of flower cultivation, in particular to a method for promoting rooting of petunia cuttings. Background technique [0002] Solanaceae, petunia, also known as petunia. Perennial herb, often cultivated as a biennial. It is suitable for indoor and outdoor cultivation and ornamental, or hanging pot planting. Petunias are large and colorful, with rich colors. They are vigorous-growing decorative flowers, and they can be reproduced on the market every year. They can be widely used in flower bed layout, planter configuration, scenic spot decoration, window sill decoration, and home decoration. [0003] Petunias are not easy to bear fruit, and the seeds are very small and difficult to obtain. The germination rate of ordinary seeds is about 60%, and the germination rate of hybrids is higher, but the seeds are more expensive. Moreover, the high cost, long period and troublesome operation seriously restrict the exte...
