Description
Technical Field
The invention belongs to the technical field of plant cultivation, and particularly relates to a water planting method for Debao-Su iron seedlings.
Background
Debao Su ironCycas debaoensisY.c.zhong et c.j.chen) genus Cycadaceae per.cycas linn.
Hydroponic cultivation refers to the cultivation method that the root system of the plant after the planting is directly contacted with nutrient solution, and the cultivation aims of ornamental, teaching, scientific research and the like are mainly achieved. The Debao cycas root system is divided into normal roots and coral roots, wherein the normal roots are fleshy roots, drought resistance and waterlogging resistance, and the soil is easy to rot when the humidity is too high; coral roots can be symbiotic with cyanobacteria to fix nitrogen, so that der-baofu Su Tieke can survive in barren and arid mountain areas. At present, soil cultivation is mainly adopted for cultivating Debao-cycas, and a slightly acidic cultivation machine with good ventilation and water permeability is needed in cultivation. There is no disclosure of planting debarking cycas seedlings in a hydroponic manner.
Disclosure of Invention
The invention aims to solve the problem of limitation of water culture of Debao-perilla-iron seedlings and provides a simple, convenient and easy-to-operate water culture planting method of Debao-perilla-iron seedlings.
In order to achieve the above object, the technical scheme of the present invention is as follows:
a water planting method for Debao-Su iron seedlings comprises the steps of root system treatment, plant fixation, water planting domestication and maintenance management, wherein after the Debao-Su iron seedlings are trimmed and the bactericide root systems are soaked, pebbles are used for fixing the seedlings in a field planting basket, the seedlings are placed in a container, clear water or culture solution is added, plant growth conditions are observed at proper time, and the liquid in the container is replaced every week; mainly comprises the following steps:
(1) Root system treatment: lifting the Debao storax seedling from the culture medium, cleaning the root residual medium or soil with flowing clean water, shearing off rotten roots, weak roots and broken roots, flattening the cut, and soaking the root system with bactericide to obtain sterilized plants for later use;
(2) Fixing plants: the cobble is used for fixing plants, a layer of cobble is firstly padded at the bottom of the field planting basket before fixing, so that the original root system is prevented from directly penetrating out of the bottom of the field planting basket, the plants subjected to pruning and sterilization in the step (1) are placed into the field planting basket, and the cobble is continuously added to fix the plants in the field planting basket;
(3) And (3) water culture domestication: sleeving the planting basket with the plants fixedly arranged in the step (3) into a container, adding clear water or culture solution into the planting basket, allowing the solution to flow through pebbles, dripping the solution into the container, and stopping adding the solution until the solution in the container is level with the bottom of the planting basket;
(4) And (3) maintenance management: the growth of plants is observed at proper time, and the liquid in the container is replaced every week.
Preferably, the Debao cymbidium seedlings in the step (1) are healthy seedlings without diseases and insect pests for 1-3 years; the bactericide is a potassium permanganate aqueous solution with the volume concentration of 0.05-0.1% or a water 800-1000 times solution of 50% carbendazim wettable powder; the soaking time is 30+/-5 min.
Preferably, the ventilation gap of the planting basket in the step (2) is larger than 8mm, the diameter of the pebbles is larger than that of the ventilation gap of the planting basket, and the pebbles are not easy to fall from the gap.
Preferably, the environment for curing management in the step (4) is 15-35 ℃ and 50-90% of humidity, so that direct insolation by sunlight in noon is avoided.
Preferably, if no root or root system of the water is soft and rotted in the maintenance and management process in the step (4), the condition of the root system in the field planting basket is checked by turning over the tray, the diseased root and the rotted root are timely sheared to a healthy place, the plants, the field planting basket and the pebbles are washed by flowing clean water, and then the steps (2), (3) and (4) are continuously repeated.
Preferably, the vessels and pebbles used are sterilized by soaking with 0.3% potassium permanganate by volume prior to plant fixation in step (2).
Preferably, after the planting basket in the step (3) is sleeved into the container, a gap of more than 5cm exists between the bottom of the planting basket and the bottom of the container.
The pebbles are paved at the bottom of the field planting basket, so that the condition that the original soil rooting system is directly soaked in water to directly necrose is avoided; the liquid in the container is flush with the planting basket, the whole planting basket forms an environment which gradually changes from dry to wet from top to bottom, the upper part is similar to barren and arid soil conditions in the original environment of the Debao-Su-iron, the survival of the as-planted Debao-Su-iron seedlings can be ensured, the lower part promotes the downward growth of the new root systems of the Debao-Su-iron seedlings to absorb water and nutrition, so that the planting basket is gradually suitable for the environment which is further stretched into water from wet, meanwhile, the Debao-Su-iron can form coral roots with the function of fixing nitrogen, so that water culture can be completed by using clear water, and the vigorous growth can be promoted if nutrient solution is added. The culture solution is commercially available general water culture nutrient solution, such as Shui Peiwang nutrient solution produced by Guangzhou Li Huajiang agricultural Co., ltd.
The invention has the following advantages and beneficial effects:
1. the invention breaks through the traditional concept that the cymbidium plants are drought-resistant and waterlogging-resistant, and the root system is not water-resistant, successfully applies the water planting technology to the culture of Debao cymbidium seedlings, and can ensure the survival rate of the cymbidium plants; the root system of the water-cultured Debao-Su-iron seedling can extend into water, can clearly and intuitively observe the growth and the form of the root system, is a good science popularization teaching material, can easily obtain a complete root system, can be used for scientific research, lays a foundation for protecting biodiversity, and has good ecological benefit and social benefit.
2. The Texaku is a evergreen pure-sun tree species, grows slowly, is suitable for being placed in indoor areas such as home, offices and the like, and the Texaku seedlings obtained by planting in a water planting mode are clean and clean, so that peculiar feather leaves can be observed, special root systems can be seen, the Texaku has unique value and charm, the living grade is improved, the market demands of Texaku gardening can be met, and good economic benefits are achieved.
3. The invention has the advantages of less material consumption, easily available materials, no need of special materials, low cost, simple operation and easy popularization and application.
