Ginger like warm and humid environmental conditions, do not tolerate low-temperature frost, more than 16 ℃ began to sprout, seedling growth temperature 20 ~ 25 ℃, stem and leaf growth temperature 25 ~ 28 ℃, 15 ℃ below the stop on the growth, so the ginger planting time is generally late April to early May, the low heat valley area in March, the middle of March is appropriate, after the germination or with the film cultivation can be appropriate earlier.

Ginger sowing time ginger sowing time is generally late April to early May.

The ginger seed should be selected before sowing, remove mold, rot, shriveled pieces of sick and weak ginger. Seed ginger to choose 50-100 grams of 1-2 strong buds of ginger is good, too large ginger can also be sown but need a large amount of seed, high cost, can be cut with a knife or hand-feeding open, but the wound should be grass ash or lime disinfection before sowing.

Ginger sowing before the best use of agents to soak the seeds to promote germination, the method of seed ginger spread out to dry 1-2 days with 1:l:120 Bordeaux liquid soaked seeds for 10 minutes, then the seed ginger fish out, with the tide of sand will be stacked in layers to cover with a film, the thickness of about 30-40 centimeters, so that the temperature is maintained at 20 -30 ℃, 8-10 days can be sprouted, according to the size of the buds, strong and weak grading sowing. The amount of seeds used per mu 300-500 kg.

Ginger planting conditions

1, temperature: ginger is native to China's tropical and East India, like warm, rhizome (ginger) growth requires higher temperatures. Above 16 ~ 18 ℃ in order to germinate, in 20 ~ 27 ℃ when the rapid development of ginger, the average monthly temperature of 24 ~ 29 ℃ is the most suitable for rhizome division, below 15 ℃ to stop growing, up to 40 ℃ when the germination is still not impeded. But below 10 ℃ below, ginger pieces are easy to rot.

2, light: ginger shade tolerance and intolerance of strong sunlight, the length of sunlight requirements are not strict. Therefore, cultivation should take shade or use the appropriate shade between crops to avoid strong sunlight.

3, water: ginger's root system is not developed, drought and flood resistance performance is poor, so for the water requirements of extra attention. During the growth of the soil is too dry or too wet on the growth of ginger expansion are unfavorable, are prone to cause morbidity and decay.

4, soil nutrition: ginger like fertile loose loam or sandy loam, planted in the sticky wet low-lying growth is poor, poor water retention in the barren land growth is not good. Ginger needs the most potash fertilizer, nitrogen fertilizer followed by the least phosphate fertilizer.

1, the pre-preparation of the pre-preparation is generally selected to raise soil. There is a detail in the selection of this piece is that everyone in line with the ginger block fat, complete appearance, clear section of the descending fast to prioritize the selection of seedling with more. Many people think that the ginger block buds less, divided seed block is large, easy to live, in fact, the ginger seedling vigor is far less than the buds more. Nurture soil this piece of many people are to clean up the grass, and then pile up some fertilizer thought can be.

In fact, it is best to dry the grass pulled out of the sun and then buried back into the soil, because the grass itself rotting to provide the fertilizer is the most suitable for this piece of soil. Then the soil will be trimmed into a strip arrangement, the application of fertilizer in the soil about 5 cm below, sandy strong suddenly for the best.

2, planting maintenance ginger is a kind of warmth, refusing strong light crops, the soil must be fertile. When planting the weather is too cold can be covered with some straw, general ginger into the soil 3-4 cm deep, do not touch the fertilizer. The amount of planting per acre is about 300 pounds, and the spacing is about 15-20 cm. The whole need to keep the soil has a certain degree of wetness, followed by sprouting attention to observation, general growth is not as normal as the need for fertilizer. Under normal circumstances in the growth of ginger seedlings about 10 cm to start fertilizer.

3, field management daily attention to temperature control, when the direct sunlight is too strong, it is best to add shade to the field. The general production process requires fertilizer 4-6 times, according to the local soil fertility to grasp. The next thing is to focus on loosening the soil, usually every three months or so, loosening the soil distance into the soil about 4 cm. For the weeds in this regard, we do not have to worry too much, just need to clean up some of the larger grass, especially the kind of creeping weeds, other small grass due to shallow root system will not threaten the growth of ginger.
