Balcony new favorite turnip cabbage soilless cultivation method

Balcony new favorite turnip cabbage soilless cultivation method, turnip cabbage is radish shortly after the emergence of the leaves to reach four or so when the plant, this time the seedling can be boiled in soup, stir-fry, but also can be pickled, the taste is very good. Introducing the new favorite of the balcony turnip cabbage soilless cultivation method.

1, variety selection

Choose faster growing radish varieties, to use the full grain, no damage, strong germination, high germination rate of the year of production of new seeds.

2, the production site

Radish production on the temperature, humidity conditions are not high, generally do not need too much light, but requires fresh and smooth air. Put on the balcony ventilation, or terrace can be.

3, the specifications of the foam box

Various specifications of the foam box can be, generally choose the length of 60 centimeters, 40 centimeters wide, 25 centimeters high box, the bottom of the box is required to be flat, there are drainage ventilation holes.

4, sowing

First, the seeds are scrubbed, the chaff floating in the water and impurities removed. Then placed in 20 ℃ of warm water soaked 12-17 hours, the middle of the panning for fresh water 1 time. Put a layer of newspaper on the bottom of the foam box, spread 2 cm thick clean river sand, the soaked seeds evenly sprinkled on the sand surface in the box, and then covered with a layer of black plastic film on the foam box to heat preservation, moisturizing, shading. The temperature inside the box is kept at 23-28℃, and water is sprayed 2-3 times a day.

5, cultivation management

Turnip vegetable growth temperature of 18-25 ℃, summer to more water spray cooling, winter to strengthen insulation. During the growth period 3-4 times a day, to clean well water is appropriate, each time the amount of water to sprouts all wet, substrate wet to the degree. Cultivation period indoor should be kept dark, not light, otherwise it will make the peanut buds turn green, affecting the appearance and taste.

6, harvest

In the normal cultivation environment, from sowing to harvest, summer, fall 7-8 days, winter, spring 8-10 days, when the sprouts are 12-15 cm long, the top petal unfolded without cotyledons now exposed, No rotten stems, no odor, no need to root, can be harvested.

The new favorite of the balcony radish vegetables. Soilless culture method 2

First, the choice of varieties of radish seedlings

Sowing Seed Select new seeds for hydroponic production of radish seedlings. The seeds are picked out of impurities and soaked in water overnight, skimming off the floating seeds, then fishing out the seeds and loading the tray. The seedling tray is lined with a layer of paper, the purpose of which is to prevent the roots from sticking into the holes of the tray, which is difficult to clean.

After sowing, cover the seeds with another layer of paper to prevent the seeds from moving when watering. The amount of seeds sown is 50-100 grams per tray (dry seeds).

Second, planting radish seedlings temperature and humidity management

Radish seeds can germinate at 2-3 ℃, germination temperature 20-25 ℃. Seedlings can withstand -2 - 3 ℃ low temperature and 25 ℃ high temperature, 5-25 ℃ can be better growth, growth temperature 15-20 ℃. The temperature is too high radish seedlings are easy to mold, too low radish seedlings grow slowly or even stop growing. The goal of temperature management is to control the ambient temperature in the radish seedlings growth temperature range (15-20 ℃), can not exceed the range of 5-25 ℃.

Radish seedlings are easy to mold under high humidity (especially in the high temperature season), so the humidity of the growing environment needs to be controlled at less than 70%, mainly by strengthening ventilation to reduce humidity.

Third, the water management of radish seedlings

After sowing, water two times a day, in case of cloudy rainy and snowy days can be discretionary water once. The cotyledons just unfolded immediately removed the paper covering the upper layer. Start watering the nutrient solution after the plant is 3 centimeters tall. If you use old seeds for hydroponics, it is especially important to water the nutrient solution at a later stage, otherwise the radish seedlings will grow slowly and easily rot seedlings.

A simple recipe for the nutrient solution is: a bucket of water (15 liters) with 5 grams of urea and 7 grams of potassium dihydrogen phosphate.

Four, radish seedlings hydroponic notes

Radish seedlings cultivation, the choice of varieties can be determined according to need. The seeds will be soaked for 3-5 hours, after which the water is dried and wrapped in moisture-absorbent paper into the germination box, maintaining a temperature of 22 ℃, relative humidity of 70% -75%, and often turned to promote air flow, to be the embryonic root is born, the seed will be sown in a perforated polyester foam board sowing holes, so that it is floating in the nutrient solution of the seedling bed. No nutrient solution is applied on the first day after sowing, and when the roots elongate and the cotyledons unfold, the nutrient solution is poured, preferably in combination with ultrasonic mist cultivation, to accelerate their growth.
