Description

Rejuvenation and repair method for potted miniature China rose

Technical field:

the invention relates to a rejuvenation and repair method for potted miniature China rose, and belongs to the field of plant cultivation.

The background technology is as follows:

china rose is an ornamental plant of Rosa genus of Rosaceae family, and is widely used for garden cultivation. China rose is one of ten flowers in China, is popular among people, and plants are vulnerable to attack by diseases and insect pests. As the miniature China rose is shorter and the branches and leaves are dense, once the China rose plant is infected with diseases and insect pests such as black spot disease, red spider and the like, the spreading speed of the China rose plant is higher and the China rose plant is difficult to control; some plants are polished rod flowering after fallen leaves, and China rose plants are severely damaged. Therefore, during the growing season, it is necessary to quickly rejuvenate the fallen leaves of China rose after flowering.

The invention comprises the following steps:

the invention mainly solves the technical problem that aiming at most of the leaves of the miniature China rose affected by plant diseases and insect pests to fall off, only few plants with weak growth vigor of the leaves remain, and an effective plant rejuvenation and repair method is provided after flowering.

The aim of the invention is achieved by the following technical scheme:

a rejuvenation and repair method for potted micro China rose comprises the following steps:

step one, pruning the miniature China rose for the first time, cutting off residual flowers, diseased branches, diseased leaves and withered and yellow branches, cleaning the residual leaves in a pot, loosening soil, removing the surface soil of the pot, adding mixed soil (humus soil: sandy soil: field soil=3:1:1) into the pot, irrigating the root for 1 time by using a carbendazim solution added with trace rooting powder, and transferring the potted China rose into a growing environment (1): the ventilation is good, the temperature is 20-26 ℃ in daytime and 12-16 ℃ at night, the time of directly irradiating the plants with sunlight every day is 4-6h, and the plants are in a light scattering environment in the rest daytime; after 3d, roots were irrigated 1 time with a solution of soluble compound fertilizer a (nitrogen: phosphorus: potassium=15:10:30) and grown 7 d.

Step two, adding biological bacterial fertilizer into pot soil, irrigating roots 1 time by using a solution of a soluble compound fertilizer B (nitrogen: phosphorus: potassium=30:20:20), spraying urea solution with 0.1% on branches 1 time, promoting the branches to emit new buds, and irrigating the solution of the soluble compound fertilizer B1 time every 7 d; after a plurality of new buds grow on the branches, carrying out secondary pruning, shearing 1/3-2/3 of the height of the branches, shearing weak branches and overlapped branches, thinning cross branches, and reserving 1-3 buds on each branch; after pruning, roots were watered 1 more time with the soluble compound fertilizer B solution.

Transferring the potted miniature China rose to a conventional growth environment after one week, and irrigating the roots with a solution of a soluble compound fertilizer C (nitrogen: phosphorus: potassium=20:20:20) for 1 time every 7-10 d; and spraying the plants for 1 time by using a foliar fertilizer solution containing medium and trace elements; the pesticide is sprayed conventionally.

The medium trace elements in the third step comprise magnesium, iron, calcium, zinc and boron.

Step four, moderately thinning buds in a bud period, adding a small amount of decomposed organic fertilizer into pot soil, and irrigating roots with a solution of a soluble compound fertilizer D (nitrogen: phosphorus: potassium=10:30:20) for 1 time every 7-10D; and the plants are sprayed with 0.1% potassium dihydrogen phosphate solution for 1-2 times, and the pesticide is sprayed conventionally.

The invention has the following beneficial effects:

the rejuvenation and repair method for potted miniature China rose provided by the invention is used for carrying out secondary pruning on the China rose branches, carrying out light pruning for the first time, improving the growth environment and being beneficial to plant growth; spraying diluted urea solution on the branches to promote the germination of new buds on the branches, and pruning and shaping for the second time after a plurality of new buds emerge on the branches; in the initial rejuvenation period, potash fertilizer is mainly applied to strengthen roots and stems, biological bacterial fertilizer is utilized to improve soil, and then nitrogenous fertilizer and phosphate fertilizer are timely added to promote the robust growth of China rose plants. The method is simple to operate and convenient to popularize, and can promote the quick rejuvenation of the China rose plants.

The specific embodiment is as follows:

an embodiment of the invention is further described below:

the rejuvenation and repair method for potted micro China rose provided by the invention is mainly used for solving the problem that most of the leaves of the micro China rose are affected by plant diseases and insect pests and fall off, and only few plants with weak growth vigor of the leaves are left.

In middle and late 5 months, the miniature China rose is trimmed for the first time, residual flowers, diseased branches, diseased leaves and withered and yellow branches are cut off, residual leaves in a pot are cleaned, soil is loosened, the soil on the surface layer of the pot is removed, mixed soil (humus soil: sandy soil: field soil=3:1:1) is added in the pot, roots are irrigated for 1 time by using a solution 800 times of 50% carbendazim wettable powder added with trace rooting powder, and the potted miniature China rose is transferred to a growing environment (1): the ventilation is good, the temperature is 20-26 ℃ in daytime and 12-16 ℃ at night, the time of directly irradiating the plants with sunlight every day is 4-6h, and the plants are in a light scattering environment in the rest daytime; after 3. 3d, the solution was diluted 1000 times with a soluble compound fertilizer a (nitrogen: phosphorus: potassium=15:10:30) (12 more flowers), and roots were irrigated 1 time and grown 7. 7 d.
