When is the latest planting time for ginger?

Ginger likes warm and humid environmental conditions, does not tolerate low temperature and frost, begins to sprout above 16 ℃, suitable temperature for seedling growth is 20: 25 ℃, suitable temperature for stem and leaf growth is 25: 28 ℃, and growth stops below 15 ℃, so ginger is generally planted from late April to early May, and it is suitable for early and middle March in low-heat valley area.

Ginger sowing time

The sowing time of ginger is usually from late April to early May.

Ginger species should be carefully selected before sowing, and weak pieces of ginger that are moldy, rotten and withered should be removed. Ginger should be planted with 50ml 100g ginger pieces with 1 Mel and 2 strong buds, too large ginger pieces can also be sown, but the seed quantity is large, the cost is high, and you can cut it with a knife or open it by hand, but the wound is disinfected with plant lime or lime before sowing.

Before sowing ginger, it is best to soak the seeds with chemicals to promote sprouting. The method is to spread the ginger to dry for 2 days and then soak the seeds with 1:l:120 Bordeaux solution for 10 minutes, then remove the ginger, stack it layer by layer with damp sand and cover it with a thin film, with a thickness of about 30 ℃, keep the temperature at 20 ml for 30 min, and sprout in 10 days, and sow according to the size, strength and strength of the buds. The amount of seed used per mu is 300 Mu and 500 kg.

Planting conditions of ginger

1. Temperature: ginger is native to tropical China and East India, and its sex likes warmth. Higher temperature is needed for rhizome (ginger) to grow. The ginger can only germinate when it is above 16-18 ℃, and the ginger develops rapidly at 20-27 ℃. The monthly average temperature is 24-29 ℃, which is the most suitable for rhizome differentiation. It stops growing below 15 ℃, and there is no hindrance to germination when it reaches 40 ℃. But below 10 ℃, ginger pieces are easy to rot.

2. Illumination: ginger is shady but not resistant to strong sunshine, and the requirement for sunshine length is not strict. Therefore, during cultivation, shade sheds should be built or crops should be used for proper shading to avoid strong sunlight.

3. Moisture: the root system of ginger is underdeveloped, and its drought and waterlogging resistance is poor, so it pays special attention to the requirement of water. During the growth period, too dry or too wet soil is disadvantageous to the growth and expansion of ginger, and it is easy to cause rot.

4. Soil nutrition: Jiang likes fertile and loose loam or sandy loam, grows poorly in clayey, moist low-lying land, and does not grow well in barren land with poor water retention. Ginger needs the most potash fertilizer, followed by nitrogen fertilizer and phosphorus fertilizer.
