Description

Technical Field

[0001] The invention relates to a cultivation method for synchronously cultivating nutrient branches of cut roses during the flowering period, and belongs to the technical field of flower planting. Background Art

[0002] Rose( Rosa hybrida ) is a woody plant of the genus Rosa in the Rosaceae family and is the world's largest fresh cut flower variety. Matrix cultivation of cut roses is currently generally considered a high-input, high-output production model and is also the main means for producers around the world to achieve high-yield goals.

[0003] Usually, during the matrix cultivation of cut roses, layering is required to form branches that are tilted to the side of the plant, only perform photosynthesis, and provide nutrients for the plant. These branches are called nutrient branches in the industry. Under the efficient production mode of matrix cultivation of cut roses, the water and fertilizer supply operation, the continuous prevention and control operation of pests and diseases, and the flow of field management personnel under the year-round flowering state will cause a certain degree of damage to the nutrient branches, thereby restricting the efficient utilization of the nutrient branches, resulting in unsatisfactory product quality, yield, and production efficiency of flower branches during the flowering period. The state and quantity of the nutrient branches of cut roses directly affect the growth, yield, and product quality of the plants, especially the healthy and reasonably distributed nutrient branches, which directly affect the yield and quality of cut roses. Therefore, how to maintain the proper state, quantity, and reasonable distribution of nutrient branches during the flowering period during the matrix cultivation of cut roses is a key and difficult problem that needs to be solved urgently for high input and high output of matrix cultivation of cut roses. Summary of the invention

[0004] In order to achieve high-quality, high-yield and stable yield of flower branches, the present invention provides a method for culturing nutrient branches synchronously during the flowering period of cut rose substrate cultivation.

[0005] The present invention is achieved through the following specific technical scheme: a method for culturing nutrient branches synchronously during the flowering period of cut rose substrate cultivation, characterized by comprising the following steps:

[0006] 1) Growth of flower branches and nutrient branches: During the cultivation of cut roses in the matrix, the branches with a thickness of less than 0.3 cm and a length of less than 35 cm that sprout from the base of the rose plant are layered to form first-level tilted nutrient branches. Planting and management are carried out according to the routine until the first batch of flower branches grow and mature;

[0007] 2) Cut the first batch of flower branches. Cut the first batch of flower branches in step 1) at 0.5-1.0 cm above the 5 leaflets at the base of the flower branches. Then, the second batch of flower branches will sprout and grow from the cutting point of the first batch of flower branches due to the apical growth advantage, and thin new branches will sprout and grow around the base and lower position of the 5 leaflet axillary buds. Plant and manage according to the routine until the second batch of flower branches grow and mature;

[0008] 3) Cutting of the second batch of flower branches: Cut the second batch of flower branches 0.5-1.0 cm above the 5 leaflets at the bottom of the second batch of flower branches in step 2). Then, the third batch of flower branches will sprout and grow from the cutting point of the second batch of flower branches due to the apical growth advantage, and thin new branches will sprout and grow around the base of the 5 leaflet axillary buds and below. Plant and manage according to the routine until the third batch of flower branches grow and mature.

[0009] 4) The third batch of flower branches are cut. The third batch of flower branches are cut 0.5-1.0 cm above the top of the 5 leaflets at the bottom of the third batch of flower branches in step 3). At the same time, flower branches with a thickness of less than 0.3 cm and a length of less than 35 cm are selected from the weak new branches around the base of the 5 leaflet axillary buds below the cutting point of the third batch of flower branches and below. They are twisted along their bases and lie on the side of the plant to form secondary tilted nutrient branches. After that, the fourth batch of flower branches sprout and grow at the cutting point of the third batch of flower branches due to the apical growth advantage. Planting and management are carried out according to the routine until the fourth batch of flower branches grow and mature;

[0010] 5) Repeat steps 2), 3), and 4) to form three-level dumping nutrient branches, and carry out planting and management as usual until the sixth batch of flower branches grow and mature;

[0011] 6) Repeat this process until multiple levels of nutrient branches and multiple batches of mature flower branches are formed;

[0012] 7) To promote the cultivation of a new batch of flower branches and nutrient branches, when the height of the base of the plant after cutting a number of flower branches is 40-45 cm above the moisture surface, choose to carry out a lowering pruning in mid-to-late March. Specifically, the height of the base of the plant after cutting the flower branches is 40-45 cm above the moisture surface to 20-25 cm, and at the same time, cut off the nutrient branches that are more than 20-25 cm above the moisture surface;

[0013] 8) For the plants in step 7) that are more than 20-25 cm away from the moisture surface, carry out a new round of multiple batches of flower branch cultivation and cutting according to steps 1)-6), as well as a new round of multi-level tilted nutrient branch cultivation and secondary stake lowering pruning, so that the height of the stake at the base of the plant is continuously raised to obtain high-yield, high-quality cut roses.

[0014] The cut rose substrate cultivation process in step 1) is conventional cultivation.

[0015] The conventional planting management includes: conventional water and fertilizer application management, conventional pest and disease control management, and conventional lighting, ventilation, and temperature management.

[0016] The present invention has the following advantages and effects: according to the germination characteristics of rose flower branches, after each batch of flower branches are cut, the present invention makes full use of the plant top advantage to germinate and grow the next batch of flower branches, and at least performs dumping nutrient branch cultivation every two batches to guide the nutrient branches to germinate on branch piles at different plant bases, so that new flower branches are continuously cut and sprouted, dumping nutrient branches are continuously formed, and the pile mouth at the base of the plant is continuously raised, so that the growth point of the flower branch is always kept at the upper part of the nutrient branch, ensuring that the base of the flower branch is ventilated and breathable and is not affected by the previous batch of nutrient branches, effectively reducing the occurrence of diseases at the base of the flower branch, supplying sufficient nutrients to the flower branch, continuously maintaining the best growth and development state of the flower branch, and realizing high-quality, high-yield and stable-yield cut rose substrate cultivation.
