How to carry out simple soilless seedling cultivation How to do this soilless cultivation of seedlin

Soilless seedling cultivation is also called nutrient solution seedling, that is, the solid matter with good aeration and water absorption such as gravel, slag, rice husk, etc. is used as the substrate without soil, and the method of spraying nutrient solution is used to meet the requirements of seedlings for nutrition and water.

1) Preparation of culture medium: The sowing culture medium of nightshade fruit can be prepared with 90% perlite and 10% culture soil. The culture soil must be disinfected.

2) sowing and seedling promotion and seedling emergence are carried out in the room (for the sealed chamber), the volume is generally 8 10 meters 3, and the indoor is provided with multi-layer seedling tray frames.

3) Greening should be carried out in a greening greenhouse with good thermal insulation performance. When the sown seeds are partially just emerging, the seedling tray is moved to the green room in time, and the seedlings are irradiated by sunlight in the green room, and the color of the cotyledons turns green. The greening period is generally until the cotyledons of the seedlings are fully planted and greened.

It takes 6 days for tomato seedlings to green.

4) Seedling transplanting is carried out in the seedling transplanting shed, and its type varies according to the conditions, and can be carried out in greenhouses, greenbeds, plastic beds and plastic large and medium sheds.

Summary. Hello dear. There are many kinds of soilless seedlings.

1.Seedling management of soilless seedlings: use containers and air for temperature and humidity management, control outdoor temperature, humidity and light, keep indoor and outdoor temperature, humidity and light mild and stable, achieve a certain temperature increase or cooling, and air circulation.

2.Fertilization of soilless seedlings: According to outdoor experiments, an appropriate amount of compound inorganic fertilizer is applied in the nursery to control the regular drip irrigation of water and nutrient ions to avoid the disease of seedlings caused by excessive nutrient concentration.

3.Pesticide management of soilless seedlings: semi-open management in the container is adopted to maintain indoor air circulation, and some effective ingredients with low toxicity, low residue, safety and efficiency are selected to control pests and diseases, so as to achieve the goal of soilless seedlings.

4.Soilless seedling potting: in the seedling planting or seedling season, choose fresh materials to prepare pots, that is, the growth environment of the plant is the pot, the internal temperature and humidity of the pot are required to be consistent with the outdoors, keep ventilation and light, and use it to transplant seeds or young seedlings.

Soilless seedling potted plants: in the seedling planting or seedling season, choose fresh materials to prepare pots, that is, the growth environment of the plant is the pot, the internal temperature and humidity of the pot is required to be consistent with the outdoor thick and wide fingers, and the rock is equipped with ventilation and light, and the seeds or young seedlings are transplanted with it.

This could be hydroponics, where plants are planted in a specific nutrient solution, which is changed regularly, and different plants have different formulations of nutrient solutions.

Soilless cultivation What are the specific steps for planting vegetables?

Vegetable selection: Fruits and vegetables that can be cultivated without soil are: tomatoes, cucumbers, bitter gourds, strawberries, cherry radish.

Leafy vegetables include lettuce, celery, coriander, bok choy, rape, water spinach, lotus artemisia, etc. The ripening period of these dishes varies. Fruit and vegetables are generally 3 to 5 months, and leafy vegetables are generally 2 to 3 months.

The temperature of fruits and vegetables is about 10 25 degrees, and the light is seen all day, and the requirements for leafy vegetables are relatively small, and the average family is suitable for planting. Agricultural research institutes and seed companies in various places have vegetable seeds for sale.

Utensils preparation: discarded plastic cups, the bottom of the cup is pierced for seedlings. Plastic flower pots or styrofoam boxes (with holes in the bottom) with a tray at the bottom.

Don't use clay pots. 0 5 kg of gravel and 1 2 kg of perlite (available in building materials stores), vermiculite, peat, rock wool. There are two kinds of concentrated nutrient solution, No. 1 and No. 2, which must be used for comprehensive dilution.

2 empty plastic bottles (for diluting nutrient solution).

Seedling: Seed invasion. Seeds should be soaked in warm water at 32°C for 6 hours.

Soak the substrate. Soak the gravel and perlite in water and set aside. Sow.

Seedlings are filled with soaked substrate in plastic cups, fingers dig holes, 2 seeds per hole of fruits and vegetables, dig ditches for leafy vegetables, and sow seeds along small ditches. Cover with a substrate and press lightly, cover with a plastic bag or film and wait for the seedlings to emerge.

Management: Pouring. After the emergence of seedlings, water the diluted nutrient solution 1 2 times a day, and the exudative liquid in the tray is appropriate. The nutrient solution can be selected as Bika potassium dihydrogen phosphate.

Introduction of soilless culture greenhouse: According to the varieties of planting, the place of use and the use, we divide the artificial light plant factory into leafy vegetable plant factory, seedling plant factory, fruit and vegetable plant factory, fungus plant factory, Chinese herbal medicine and high value-added plant factory, research plant factory and plant factory used in special places. With the improvement of people's requirements for food quality and the needs of human survival in special areas, the application of artificial light plant factories will become more and more extensive.

The use of all facilities and equipment in the plant factory, and the implementation of high-tech are inseparable from power. Plant factory power usually chooses photovoltaic power generation, but the power is not stable enough, in order to make the voltage stable, 380V is chosen. For the sake of safety, it is advisable to take a dark line.

The load and distribution of wires should be determined according to the actual situation, and should be strictly calculated correctly, and there is room to ensure safe electricity use, normal electricity consumption, and electricity saving. The plant factory should be equipped with a full-time electrician technician and a backup generator to ensure the normal operation and safe operation of the plant factory.

Introduction to the column-based hollow cultivation system.

Pillar soilless culture is a kind of substrate cultivation, which aims to develop the planting to space through the erected garden pillar as a cultivation carrier without affecting the ground cultivation, so as to greatly increase the planting amount and harvest on the unit plane, give full play to the production potential of the limited ground, and improve the land utilization rate by 3-5 times and increase the unit yield by 2-3 times, which is a resource-saving agriculture and factory agriculture.

Column-type soilless cultivation has the following advantages:

1. Now there is a factory production mode with high yield.

2. It has the characteristics of economical and sustainable production.

3. Due to regional restrictions, production and cultivation can be carried out in an environment where there is no soil at all.

4. The column is suitable for the growth of a variety of plants.

Classification and composition of column-type cultivation system:

The column cultivation system is divided into foam column cultivation system and PCV column cultivation system, and the foam column cultivation system is divided into oblique foam column cultivation system and integrated foam column cultivation system. Among them, the oblique foam column cultivation system needs to be equipped with planting cups, each column cultivation bowl is equipped with 5 planting cups, generally each plant is 10-12 cultivation bowls, and 50-55 seedlings can be planted. Integrated foam column cultivation system, the system comes with planting cups, generally three to five, it is characterized by no external planting cups, but the shortcomings are very obvious, the planting cup can not be taken down to regret the erection, it is inconvenient to replace the substrate soil, and it is inconvenient to clean up the residual root system of plants.

The PVC column cultivation system is also divided into movable planting cups and immovable planting cups, which has the advantages of being easy to clean, not easy to change color, and has strong bearing capacity.

Foam oblique column cultivation system materials: 1, column cultivation bowl 2, oblique planting cup 3, isolation cloth 4, filler 5, auxiliary materials, etc.;

Foam integrated column cultivation system materials: 1, column cultivation bowl 2, filler fiber 3, auxiliary materials, etc.;

PVC column cultivation system materials: 1, cultivation body 2, planting cup.

Soilless seedling cultivation refers to the use of river sand, chaff ash, vermiculite and water as seedling media, which is called soilless seedling.

Nutrient solution is used to raise flowers, usually in containers such as plastic pots, and with substrates such as vermiculite. When planting, first mix various substrates in a certain proportion or put them separately into plastic pots, and then plant seedlings that have grown 3 5 leaves in pots**. Before planting, put the roots with soil in clean water, gently wash the root mud, and then soak the roots in a solution 5 10 times thinner than the normal concentration of nutrient solution for about 10 minutes, so that they can fully absorb the nutrients.

After planting, a layer of quartz sand or small stones is spread to fix the plants, and the nutrient solution is poured from all sides of the container immediately until the nutrient solution flows out of the drainage hole at the bottom of the pot.

Water every 1 3 days, water the dilute nutrient solution every 7 10 days, and then water the nutrient solution of normal concentration after the plant returns to normal growth. Generally, during the growth period of indoor potted flowers, large seedlings are watered with nutrient solution every 7 15 days, and small seedlings are watered every 15 20 days; During the dormant period of flowers, flowers are generally not watered with nutrient solution. The number of nutrient solution each time, generally the inner diameter of the pot is about 20 cm of positive flowers, each time about 100 ml, the amount of negative flowers should be reduced.

If you are using a long-acting flower fertilizer, please refer to the product instructions for its dosage. For beginners, it is necessary to pay attention to the appropriate amount when pouring the nutrient solution, rather less than too much. If it is applied too much, it is often easy to cause harm such as scorched leaves.

First of all, let's clarify a concept: soilless does not mean that soil is not used, but that plants are cultivated using artificially configured "soil".

So why: artificially configured "soil" is called soilless?

Plants grow by absorbing nutrients (i.e., nutrients and, of course, sunlight) from nature's soil. So what are the "nutrients in nature's soil"? To put it simply, there are two main categories:

1. Organic matter; 2. Fertilizer. However, natural soil not only contains organic matter and fertilizer, it also contains germs and pests. People just think:

According to the fertilizer characteristics of the plants planted, the soil is configured with organic matter + fertilizer + inorganic matter, which not only avoids germs and pests, but also is conducive to the growth of plants. The use of configured soil for cultivation and planting is called "soilless culture".

The use of configured soil for seedling raising is called "soilless seedling".

no soil seedling

Seedlings are raised by using non-soil solid materials as substrates without soil, watering nutrient solution, or using hydroponics or aeroponics without any substrate, which is called soilless seedling raising. According to whether the substrate is used, it can be divided into substrate seedling and nutrient solution seedling, the former is the use of vermiculite, perlite, rock wool and other substrates and watering nutrient solution seedlings; The latter does not use any matrix and only uses certain supports and nutrient solutions.
