Description

Rejuvenation and repair method for potted miniature Chinese roses

The technical field is as follows:

the invention relates to a rejuvenation and repairing method of potted miniature Chinese roses, and belongs to the field of plant cultivation.

Background art:

the Chinese rose is an ornamental plant of rosa of rosaceae and is widely applied to garden cultivation. China rose is one of ten major flowers in China, is popular with people, but plants are easy to be attacked by diseases and insect pests. Because the miniature Chinese rose is short and has dense branches and leaves, once Chinese rose plants are infected with plant diseases and insect pests such as black spot and red spider, the spread speed is high and is difficult to control; some plants show polished rod blooming after falling leaves, and Chinese rose plants are seriously damaged. Therefore, in the growing season, it is necessary to rapidly rejuvenate the miniature rosa chinensis which fall leaves after flowering.

The invention content is as follows:

the invention mainly solves the technical problem of providing an effective plant rejuvenation and restoration method after blooming aiming at the problems that the miniature Chinese rose is attacked by diseases and insect pests, most leaves fall off, and only a few plants with weak growth vigor are left.

The purpose of the invention is realized by the following technical scheme:

a rejuvenation and repairing method for potted miniature Chinese roses comprises the following steps:

the method comprises the following steps of firstly, pruning a miniature Chinese rose for the first time, shearing off residual flowers, diseased branches, diseased leaves and withered and yellow branches, cleaning the residual leaves in a pot, loosening the soil, removing soil on the surface layer of the pot, adding mixed soil (humus soil: sandy soil: garden soil = 3: 1: 1) into the pot, irrigating the root 1 time by using a carbendazim solution added with trace rooting powder, and transferring the potted Chinese rose to a growth environment (I): the ventilation is good, the temperature is 20-26 ℃ in the day/12-16 ℃ at night, the time for directly irradiating the plants by sunlight every day is 4-6 h, and the plants are in an astigmatic environment in the rest of the day; after 3 d, the roots were irrigated 1 time with a solution of soluble compound fertilizer a (nitrogen: phosphorus: potassium = 15: 10: 30) for 7 d growth.

Adding biological bacterial manure into the pot soil, irrigating the roots for 1 time by using a soluble compound fertilizer B (nitrogen: phosphorus: potassium = 30: 20: 20) solution, spraying a 0.1% urea solution for 1 time on the branches to promote the buds to emerge on the branches, and irrigating the soluble compound fertilizer B solution for 1 time every 7 days; after a plurality of new buds grow on the branches, carrying out secondary pruning, cutting off 1/3-2/3 of the height of the branches, cutting off weak branches and overlapped branches, thinning and shearing cross branches, and reserving 1-3 buds on each branch; after pruning, the roots were irrigated 1 more time with soluble compound fertilizer B solution.

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

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

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

The invention has the following beneficial effects:

according to the rejuvenation and restoration method for the potted miniature Chinese rose, provided by the invention, the branches of the Chinese rose are subjected to secondary pruning and primary light pruning, the growth environment is improved, and the growth of plants is facilitated; spraying the branches with diluted urea solution to promote the germination of new buds on the branches, and performing secondary pruning and shaping after a plurality of new buds emerge on the branches; in the initial rejuvenation period, potassium fertilizer is mainly applied to strengthen roots and stems, biological bacterial fertilizer is used for improving soil, and then nitrogen fertilizer and phosphate fertilizer are added in due time to promote the robust growth of Chinese rose plants. The method is simple to operate and convenient to popularize, and can promote the rapid rejuvenation of the Chinese rose plants.

The specific implementation mode is as follows:

one embodiment of the invention is further described below:

the rejuvenation and repair method of potted miniature China roses mainly aims at the problems that most leaves of the miniature China roses are attacked by diseases and insect pests and fall off, and only a few plants with weak growth vigor are left.

In the middle and last ten days of 5 months, the miniature monthly rose is trimmed for the first time, residual flowers, diseased branches, diseased leaves and withered and yellow branches are cut off, the residual leaves in a pot are cleaned, soil is loosened, soil on the surface layer of the pot is removed, mixed soil (humus soil: sandy soil: garden soil = 3: 1: 1) is added into the pot, the root is irrigated for 1 time by using 800 times of solution of 50% carbendazim wettable powder added with trace rooting powder, and the potted miniature monthly rose is transferred to a growth environment (i): the ventilation is good, the temperature is 20-26 ℃ in the day and 12-16 ℃ at night, the time of directly irradiating the plants by sunlight every day is 4-6 h, and the plants are in an astigmatic environment in the rest of the day time; after 3 d, the roots were irrigated with 1000-fold solution diluted with soluble compound fertilizer a (nitrogen: phosphorus: potassium = 15: 10: 30) (No. 12 flowers) 1 time and grown for 7 d.
