Problems solved by technology

Soilless cultivation of container seedlings is also a key technology to solve the severe seasonal restrictions on peony seeding, breeding and transplanting. Usually peonies can only be sown in autumn, and can only germinate and grow in the following spring. Sowing in other seasons can only wait until the next spring to germinate, and the land is abandoned for at least One year; transplanting peony seedlings is easy to survive only in autumn, which is contrary to the afforestation operation in the rainy season and severely restricts the production of enterprises. The transplanting of seedlings in containerized soilless cultivation will not affect survival anytime and anywhere, which is conducive to the greening and development of peony groups. application promotion

Embodiment 1

[0012] Preparation of Soilless Cultivation Substrate of 'Fengdan'

[0013] Use river sand, charcoal, perlite, and ceramsite as raw materials, and prepare according to the method described in one of the above-mentioned invention points, river sand; charcoal, 5, 5-10, 10 mm in diameter; ceramsite, 2-5 mm in diameter; pearl Rock, 1-3 mm in diameter; its volume ratio is 1:1:0.5:0.5, mixed evenly (the following matrix formulations all contain this proportion of river sand, for the convenience of description, the river sand is omitted). The parameters of the matrix are: bulk density 0.320g / cm3, saturated water content 43%, total porosity 88%, ventilated porosity 78.8%, pH 7.52, cation exchange capacity 306.mmol / l, in line with the characteristics described in the first point of the invention.

[0014] Charcoal is ordinary wood, litter and fallen leaves are fired in ordinary charcoal kilns; after washing with water for 30 minutes, the pH can drop to about 7.25; according to the parti...

[0018] 'Fengdan' containerized soilless culture nutrient solution to irrigate plants

[0019] A peony 'Fengdan' ( Paeonia ostii T. Hong et J. X. Zhang var. lishizhenii B. A. Shen) plants are cultivated in containers. In order to ensure the normal growth of the plants, it is necessary to supply the necessary nutrients and water for the growth of the plants. The plant is a 1-3-year-old seedling, and its root system is removed from soil and cleaned, and the soilless potted plant is carried out according to the method described in Example 1, and the following nutrient solution is poured. KNO per liter of nutrient solution 3 606 mg, Ca (NO 3 ).4H 2 O 827 mg, (NH4)2H 2 PO 4 115mg, MgSO 4 .7SO 4 493 mg, FeSO 4 .7H 2 O 27.8 mg, EDTA 37.2 mg, H 3 BO 32.86 mg, CuSO 4 .5H 2 O0.08 mg, ZnSO 4 .7H 2 O 0.22 mg, MnSO 4 .4H 2 O 2 mg, H 2 MoO 4 .4H 2 O 0.09 mg, CoCl 2 0.025 mg, 2-(N-morpholine) ethanesulfonic acid (MES) 3 mmol, the rest is water, and the pH is adjuste...

[0022] Induction of Root System in Containerized Soilless Cultivation of ‘Fengdan’

[0023] The root system of peony is a fleshy root, which stores rich nutrition. Peony plants transferred from the field to potted pots usually rely on the nutrients stored in the fleshy roots to maintain growth and complete the flowering process, but with the depletion of nutrients, the growth gradually declines. In order for potted plants to continue to grow normally, new absorbing roots must be induced to absorb and synthesize new nutrients from the substrate for the plants to grow vigorously. A peony 'Fengdan' ( Paeonia ostii T. Hong et J. X. Zhang var. lishizhenii B. A. Shen) The roots of 1-3 year old plants, wash the soil, soak the rooting agent mentioned in the third invention point above and keep it moist for 30-50 minutes (it can be realized at room temperature without sunlight). The rooting agent contains IBA 80 mg, CCC 50 mg, NAA 50 mg, among them, IBA and NAA are dissolved with a...

Abstract

The invention belongs to the field of forestry seedling cultivation, and in particular relates to a soilless cultivation method of peony. After surface disinfection treatment, the peony plants are planted in the artificially prepared soilless substrate, watered with nutrient solution, and carried out daily management and maintenance. The plants grow and develop normally under soilless conditions. The invention provides a peony soilless cultivation substrate, which satisfies the physical conditions for root growth and development; a peony soilless cultivation nutrient solution, which satisfies the chemical conditions such as water, nutrition and pH required for plant growth and development; a peony soilless cultivation The daily management and protection method of cultivated plants, the root system of the plant obtains the best water, air, liquid ratio and nutrient ratio; the fleshy root system produces fibrous roots with absorption function in the soilless culture medium, which solves the key problem of the survival of peony potted plants and realizes Containerized soilless cultivation.

Description

technical field [0001] The present invention relates to a kind of peony ( Paeonia ostii T. Hong et J. X. Zhang var. lishizhenii B. A. Shen's soilless culture method. Specifically, the present invention relates to a soilless cultivation substrate capable of cultivating peony in a container, a nutrient solution that satisfies the nutrients and water required for the growth of the plant in the container; a pH adjustment method that stabilizes the pH of the plant root system within a certain range ; a compound rooting agent that promotes the growth and development of the root system; the process, conditions and steps for cultivating peony seedlings with soilless culture substrates, nutrient solutions, and rooting agents, for indoor cultivation of peonies for long-term viewing, overcoming the autumn restrictions of sowing and transplanting, and reducing nakedness. The key technology for slowing down the death of root seedlings and carrying soil pathogens. Background techniqu...
