Of all the vegetables, ginger needs the least sunshine. The light compensation point of its growth is as low as 500 lux, and it can grow well even if it is planted on a balcony with only a few hours of light. What surprises you even more is that ginger, which is growing vigorously, is a beautiful potted plant. Ginger, which has both ornamental value and edible value, is a good choice for growing vegetables on your balcony.
1, the cultivation method of ginger seedlings
You can buy some ginger with small buds and soil in the market. These fresh ginger can germinate in the shade for a few days (choose the kind with full and firm tubers).
2. Potting method
Cut the sprouted stem into small pieces, each piece should have more than three small buds. Potted soil should be loose, fertile and well-drained humus soil, and compost soil is better.
It is best to choose a wide and shallow pot for the container. Ginger can be planted in the soil about 3 cm, and the bud eyes should be facing up.
3. Growth time of ginger
Keep the container in a warm place, keep the soil moist, and make sure not to get too much sunlight. Ginger grows slowly.
It will be several weeks before you can see the buds sprouting from the soil. At this time, it is still necessary to water regularly, and often spray it with a spray bottle after germination. At this time, you should start to give some light.
4. Water demand
Ginger needs water very much for its growth. Don't let the soil dry thoroughly and don't water it too much. Potted soil cannot accumulate water.
Ginger needs high humidity and should be sprayed frequently to keep the environment moist. Air-dried spider mites should be applied with organic fertilizer or decomposed manure every 3-4 weeks.
Step 5 harvest ginger
The whole process down, maybe just for fun at first, the sprouted ginger will be planted in pots at will, but in fact, the kind of ginger on the terrace above can also be harvested. It usually grows in 4 months. Of course, the longer you keep it, the greater the harvest. When it is raised for 4 months, it can be pulled up, cut and eaten, and the buds will continue to be cultivated.
Do you think it's easy? There is a pot at home. Maybe, today you can start the first step of growing vegetables on your balcony! The following are the steps of planting ginger in the field, which are shown together for learning reference:
Step one, preparation of ginger planting area:
Ginger is planted in two ditches 180 cm wide and 10 cm deep on the border, and the bottoms of the ditches are covered with livestock manure. Apply 75 kg of cake fertilizer every 667 square meters, and apply compound fertilizer 15-20 kg as seed fertilizer. After application, the soil should be covered with 3-4 cm for planting.
Step 2, planting density of ginger:
The planting density of ginger must comprehensively consider various factors. According to the production experience and test results of netizens from all over the world, considering the fertility of ginger fields, the size of ginger planting, management level and other factors, the planting density of ginger is generally divided into the following three types:
1. If the ginger fields and planting pieces with low fertilizer and water content are less than 50g, the row spacing is 48-50cm, the plant spacing is 14- 15cm, the number of plants per 667m2 is about 9000, and the yield is about 1500kg.
2. Medium-fat ginger field, 50-75g ginger, 50cm row spacing, plant spacing16-17cm, about 8,000 plants per 667m2, and the output1500-2,250kg.
3. For example, the high-fat ginger field is 50-75g, the row spacing is 50cm, the plant spacing is 19cm, the number of plants per 667m2 is 7,000, and the yield is more than 2250kg.
In the above three types, if any factor fails to meet the requirements, the planting density should be increased accordingly.
Step 3, the planting method of ginger:
Ginger cultivation can be divided into three forms: open cultivation, flat cultivation, pit cultivation and ridge cultivation, or small arch shed cultivation; Plastic film mulching cultivation can also be carried out.
It is suggested that the plastic film mulching cultivation method should be adopted, because it has the functions of warming temperature, preserving fertilizer, preserving water and loosening soil, which can promote the early emergence of ginger, make the seedlings in Miao Zhuang grow well and vigorously, and increase production by more than 30%-50%.
Precautions for planting ginger: When planting ginger, it is best that the ginger buds are in the same direction and each row is in a straight line; When pasting ginger, the ginger buds are facing up, which is convenient for quick excavation; After planting ginger in the field, cover it with seed fertilizer and fill the ditch slightly higher. If there is not much seed fertilizer, soil can be used instead.
