When is ginger planted? How to plant it?

The planting time of ginger is generally from late April to early May, and it is appropriate to plant ginger in early and middle March in low-heat valley areas, and it can be earlier after germination or plastic film cultivation. Ginger likes warm and humid environmental conditions and is not resistant to low temperature frost. Germination begins above 16℃, the suitable temperature for seedling growth is 20~25℃, the suitable temperature for stem and leaf growth is 25~28℃, and the growth stops below 15℃.

Before sowing, carefully select ginger seeds and remove moldy, rotten and withered ginger slices. It is better to choose ginger with 50- 100g and 1-2 strong buds for planting ginger. Large Jiang Ye can be planted, but the amount of seeds is large and the cost is high. It can be cut with a knife or opened by hand, but the wound should be disinfected with plant ash or lime before sowing.

Before sowing ginger, it is best to soak the seeds with chemicals to accelerate germination. Methods The planted ginger was aired for 65,438+0-2 days, and then soaked in Bordeaux solution of 65,438+0:1:65,438+020 for 65,438+00 minutes. Then, after the ginger is taken out, it is layered with wet sand layer by layer, covered with a film with a thickness of about 30-40 cm, and the temperature is kept at 20-00. The amount of seeds used per mu is 300-500 kg.

Be sure to pay attention to watering when planting ginger. Ginger is not drought-tolerant, so the pot soil should not be too dry. Water it often, but remember not to accumulate water. There is also that ginger is not resistant to sunlight, so pay attention to shading if the light is strong.

Extended data

Ginger contains spicy and aromatic components. The irritating component is gingerol in the aromatic volatile oil. Among them, there are mainly gingerol terpenes, fennel, camphor terpenes, gingerol, eucalyptus oil essence, starch, mucus and so on.

Ginger can weaken the action of pepsin and enhance the action of lipolytic enzyme. Ginger can seriously destroy amylase in pancreatin and significantly reduce the digestion of starch by pancreatin. It can also inhibit β -amylase in amylase and hinder starch saccharification.

Ginger can act on sympathetic nerve and vagus nerve system, inhibit gastric function and directly excite gastric smooth muscle. The absorption promoting effect of sulfadiazine was studied by rat small intestine reflux method. The results show that the water extract of ginger has obvious absorption promoting effect, improves its bioavailability and gives full play to its curative effect.

Ginger extract can inhibit dog vomiting caused by copper sulfate. The gingerone and the mixture of gingerone isolated from ginger also have antiemetic effect, and the minimum effective dose is 3mg, but it is ineffective for vomiting caused by central apomorphine and pigeon vomiting caused by digitalis, so ginger is considered to have peripheral antiemetic effect.
