Otherwise, the newly sprouted new leaves will lose water and become light, and the color will be dim, and it will easily burn the leaf edge. The Lord needs to provide the Yangguan footing for photosynthetic rental.

Green radish culture temperature requirements

Although green radish does not like the hot sun, it is still very sensitive to temperature. If the temperature is too low, it is easy to be frostbitten. It can be around 20 degrees at room temperature. If heating equipment is installed, the green leaves cannot be too close to the room, and the indoor temperature is controlled above 10 degrees. Green radish can safely spend the winter.

Green carrot farming and fertilization management

Due to indoor farming, green radish does not have sufficient outdoor nutrients. It is recommended to apply fertilizer every half month. You can buy fertilizer for the green radish in the market. Or ask the florist owner to help him choose the fertilizer.

Fertilization is mainly based on nitrogen fertilizer, supplemented by potassium fertilizer. Before the spring green radish growth period, ammonium sulfate or urea 0.3% solution can be applied once every 10 days, and 0.5% o ~ 1% at the same time. The urea solution is used for foliar application for 1 time.

In the autumn and winter seasons in the north, plants grow slowly or even stop growing, so it is necessary to reduce fertilization. From May to September, it is the growth period of green radish. Fertilizer should be applied once every 2 months. In addition, a thinner liquid fertilizer is applied once every 10 days.

In addition, it should be noted that for smaller plants, only liquid fertilizer is applied.

Environmental requirements for green radish farming

Selection of green radish culture soil

Green radish is warm and humid, requiring loose, organic-rich slightly acidic and neutral sandy loam. Potted green radish should use fertile, loose, and well-drained soil. It is better to use acidic soil. It is best to use garden soil, decomposed horse manure and a small amount of peat to form a well-drained matrix; humus, peat and fine sand can also be used. Mix and change pots every 3 years.

Reproduction method of green radish

In the late spring and early summer, cut 15 to 30 cm branches, remove the leaves of the base 1 to 2 knots, and directly pot them with culture soil, 3 to 5 per pot, water the plants, plant in a cool and ventilated place, pay attention to keep The potting soil is moist, and it can be rooted and germinated in about 1 month, and in the same year, it can grow into a plant with ornamental value.

Green plant is very susceptible to problems with pests and pathogens. Typical pests affect green radish including powder scale insects, red spiders, and scale insects. Powder scale insects are usually the most common and can be killed by alcohol, cotton swabs, removed, or removed by hand.

Common diseases and insect pests

Typical pathogens (fungi and bacteria) of the green radish affect the range of green radish, usually leading to root rot, leaf spot and withering. Be careful not to over-water the water to prevent root rot. When choosing to buy a green plant, remove the plant from the pot and check its roots. See if it has a complete and healthy root.

Bacterial leaf spot

The disease occurs under high humidity conditions and affects viewing. In the early stage of the disease, there are water-stained brown spots on the leaves, and there are yellow halos on the periphery; after expansion, the lesions are nearly round, irregular, brown, with a ring pattern; the wheel marks on the leaf spots are more obvious at the late stage of the disease, yellow halo The circle exists from beginning to end.

The law of onset: the bacteria overwinter on the lesions; they are spread by water droplets. High humidity, heavy rain, spray watering, etc. are conducive to disease occurrence. The green radish is placed on the lower shelf, the ventilation is poor, and the lack of light increases the incidence.

Control method

(1) Cultivation techniques to prevent disease: Green radish should be placed on the middle basin to maintain; have higher humidity and certain light intensity; timely turn on the exhaust fan to dehumidify; spray watering is prohibited.

(2) Pharmacy protection: spray 20% ammonia copper, zinc water agent 400 times liquid, or 72% agricultural streptomycin 3000 times liquid, or 12% green milk copper emulsifiable oil 600 times liquid, or 2% added rice at the beginning of the disease. Wettable powder 2000 times liquid and the like.

Anthracnose

The pathogen is more harmful to the middle part of the leaf and can also harm the flower. At the beginning, the diseased part showed wet reddish-brown or dark brown pus-like spots. There were faint green halos around the spots. When enlarged, it showed long oval or long plaques, the edges were dark brown, and the interior was yellow-brown. A ring-shaped marking that is gathered by dark spots. It is also known as black spot or dark brown because of its dark brown color.
