What vegetables can be grown on the north balcony

1. Lettuce. Lettuce is a cold-tolerant vegetable, which likes cold climates and is not resistant to high temperatures. The germination temperature is 4 or more.

15-20 is best, if the temperature exceeds 30, it will not sprout. Its seedlings can tolerate sub-zero low temperatures, the seedling growth temperature is 15-20, and the stem growth temperature is 11-18. Lettuce likes a large temperature difference between day and night, and requires a higher temperature for flowering and fruiting, and the suitable temperature is 19-22.

2. Leeks. Leeks like cold and cool, cold and heat tolerant, the seed germination temperature is more than 12, the growth temperature is 15 to 25, and the underground can tolerate lower temperatures. Medium light intensity, strong resistance to negatives.

However, if the light is too weak, the accumulation of photosynthetic products is less, the tillers are less and weak, the yield is low, and it is easy to premature aging. The light is too strong, the temperature is too high, there are many fibers, and the quality is poor.

3. Asparagus. Asparagus is highly adaptable to temperature, hardy and heat-tolerant, and can be cultivated from the subarctic zone to the subtropics. However, it is most suitable for temperate cultivation with four distinct seasons and a pleasant climate.

In the alpine zone, when the temperature is -33 and the thickness of the permafrost layer reaches 1 meter, it can still safely overwinter, and although the yield is low, the quality is good.

The germination temperature of asparagus seeds was 5, and the appropriate temperature was 25 30, which was higher than 30, and the germination rate and germination potential decreased significantly. It can be continuously grown for more than 10 years by propagating with seeds. In winter, the shoots in the cold areas withered, and the rhizomes and fleshy roots entered the dormant period for overwintering. In warm winter areas, the dormancy period is not obvious.

4. Toon. Toon likes temperature, is suitable for cultivation in areas with an average temperature of 8-10, and its cold resistance increases with the increase of seedling age. Seeded annual seedlings can be frozen around 10.

5. Fungus vegetables. It is resistant to high temperature, drought, humidity and high nutritional value. Fungus vegetables are fed with seedlings, young shoots or young leaves, which are soft and smooth in texture and have high nutritional value.

It can be used as soup, stir-fry, hot food, cold dressing, etc., its taste is fragrant, and it is crisp and refreshing when chewing.

1. Carrots.

The seeds of carrots germinate easily at 20 25 temperatures, which takes about 5 days; The stems and leaves were most suitable for growing under the condition of 23 25, and the seedlings could tolerate high temperatures above 27. The suitable temperature for the straight root expansion stage is 13 18. Carrots have high requirements for light, especially during the hypertrophy of fleshy roots, it is necessary to ensure that it has sufficient light, otherwise it will reduce the yield and affect the quality.

During the planting period, it is necessary to ensure that the soil is moist, especially in the germination period, there can be no shortage of water, if the soil is too dry during the plant formation period, it will cause the fleshy roots to be small, rough, the appearance is not correct, and the texture is rough and hard. Carrots are suitable for growing in deep, fertile, well-drained loam or sandy loam soils. In order to have ample space for the roots to grow, the cultivation container should be at least 40 cm wide and 40 50 cm high.

2. Onions. Onions are more adaptable to temperature. Onion is a long-day crop that requires more than 14 hours of sunshine during bulb swelling and flowering. Onions should be supplied with sufficient water during the germination stage, the peak growth period of seedlings and the bulb expansion stage.

Onion has strong adaptability to soil, and it is suitable to be fertile and loose, neutral loam with good aeration, sandy loam is easy to obtain high yield, but clay loam has full bulbs, good color and luster, and is resistant to storage.

3. Baby cabbage.

Chinese cabbage is a mustard cultivated plant, the stems and leaves are edible, often cultivated as an annual, it is the most mineral-rich and vitamin-rich vegetable in vegetables.

4. Bracken, also known as water spinach.

Native to the south, it prefers warm, humid climate, is resistant to heat and frost, and can grow in all provinces in the Yangtze River basin in April and October. Native to China, it is widely cultivated as a vegetable, or sometimes in the wild. It is commonly cultivated in the central and southern provinces of China.

It is found throughout tropical Asia, Africa and Oceania.

5. Artemisia chrysanthemum. Artemisia chrysanthemum is a semi-cold-tolerant vegetable, which does not have strict light requirements, and is generally better to have weaker light. It is a short-day vegetable, which is conducive to its growth in a cold and mild environment, and the relative humidity of the soil is kept at 70%-80%. Under long sunshine conditions, vegetative growth can not be fully developed, and soon enters reproductive growth and flowering and seed bearing.

Native to the Mediterranean, it has been cultivated in China for more than 900 years and is widely distributed, but the cultivation area in the north and south is very small. It is distributed in Anhui, Fujian, Guangdong, Guangxi, Guangzhou, Hainan, Shijiazhuang, Hebei, Hubei, Hunan, Jilin, Shandong, Jiangsu and other provinces.

The north-facing balcony has almost no sunlight throughout the day and the widest selection of vegetables.

Small. Shade-tolerant vegetables should be selected for planting, such as lettuce, leeks, asparagus, toon, dandelion water spinach, fungus, onions, lettuce, rape, leeks, loofahs, coriander, radish, etc.

Some vegetables will be burned by the sun, and the light ones will lose their leaves, and the heavy ones will die, so it is best to plant vegetables with vines and high temperature resistance in the corner of the balcony. During the summer months, you will also have to try to defend yourself against the glare and radiant light reflected from the back floors.

Generally speaking, if space permits, most fruits and vegetables can be grown on the balcony. The so-called environmental conditions of the balcony are mainly the balcony orientation and the closure of the balcony. The orientation determines the light conditions of the balcony, while the enclosed condition of the balcony determines the temperature conditions of the balcony.

The temperature of the fully enclosed balcony is also higher in winter, and the temperature limit is smaller, and the range of vegetables that can be selected is also relatively wide, and vegetables can be grown all year round. Semi-enclosed or unenclosed balconies have low temperatures in winter, and it is generally not easy to grow vegetables in winterExtended Materials

Management of the growing season.

1) Moisture management. Keep the buds moist throughout the growing season. After sowing and before the upright growth of the buds, water 2 3 times a day, and after the upright growth of the buds until before harvesting, increase the amount of watering, 3 or 4 times a day.

The amount of water should be drenched each time so that all the buds are wet and the substrate is also wet, but not so that there is water at the bottom of the cultivation container.

2) Temperature management. In summer, ventilation should be strengthened, water spraying for cooling, and shading; In winter, indoor insulation should be strengthened.

3) Lighting adjustment. Pay attention to shading in the early stage of growth, and when the sprouts reach a certain height and are close to the harvest period, increase the light 1 day before harvest to make the sprouts green.

The south-facing balcony is full of sunshine and good ventilation, making it the ideal balcony for growing vegetables. Almost all vegetables grow best in full sunshine, so general vegetables can be grown on south-facing balconies all year round, such as cucumbers, bitter gourds, tomatoes, beans, goldenrod, apricots, mustard greens, zucchini, green peppers, lettuce, leeks, etc. In addition, aquatic vegetables such as lotus root, water chestnut and water chestnut are also suitable for planting on south-facing balconies.

In winter, most of the south-facing balconies can be exposed to direct sunlight, and simple insulation equipment can also create a good environment for the production of vegetables in winter.

The east-facing and west-facing balconies are half-sunshine, suitable for planting light-loving and shade-tolerant vegetables, such as onions, oily lettuce, small rape, leeks, loofahs, coriander, radish, etc. However, the temperature of the west-facing balcony is higher in the summer when the west is sunburned, so that some vegetables produce daily burning, the light ones fall leaves, and the heavy ones die, so it is best to plant vegetables with vines and high temperature resistance in the corner of the balcony. During the summer months, you will also have to try to defend yourself against the glare and radiant light reflected from the back floors.

The north-facing balcony has little to no sunlight throughout the day and a minimal selection of vegetables. Shade-tolerant vegetables should be selected for planting, such as lettuce, leeks, asparagus, toon, dandelion water spinach, fungus, etc. During the summer months, you will also have to try to defend yourself against the glare and radiant light reflected from the back floors.

I also have a north balcony at home, and I grow amaranth in the spring, fungus in the summer, and 2 lentils. Now prepare to plant greens, mustard greens, lettuce and lettuce.

1.Suitable for shade-tolerant vegetables in the area north of the Tropic of Cancer in China, the north balcony almost does not see direct light throughout the year, in the area south of the Tropic of Cancer, such as Guangdong, Guangxi and Yunnan and other provinces of some bridges and bend areas, the north balcony has a small amount of sunlight throughout the year, and there is sufficient direct light around June 21 in summer. Vegetables usually grow weak due to insufficient light on the north balcony, so shade-tolerant and short-day vegetables should be planted that do not require much light.

2.You can choose vegetables that are shade-tolerant vegetables such as ginger, shallots, garlic, lettuce, coriander, rape, rich cabbage, lettuce, leeks, asparagus, water spinach, fungus, beets and Taiwanese watercress, etc., and the north balcony can also grow sweet potatoes, peas and radishes to pick seedlings to eat.
