Cultivation characteristics
-start time of cold treatment: October 15-November 15
-Cold storage / rooting chamber or natural cold treatment cycle: 20-21 weeks "wet cold" treatment (after planting)
-Cold treatment temperature: the root system developed to a low temperature of 9 °C, and then, according to the growth of the bulb, the temperature dropped to 5 to 1 °C (the same as the cold treatment of tulips).
-the number of weeks of the cold cycle + the earliest date of admission: see table below
-planting period: October 15-November 15
-Matrix: a matrix or standard matrix soil with good drainage and strong water retention, with a PH value of about 6-7.
-number of bulbs per pot: see table below
-planting depth: the bulb is covered with 1-2 cm of soil
-watering: after planting in the normal wet matrix soil, watering the right amount, and then watering until the bulb begins to sprout.
-Natural cold treatment: in areas where the temperature is very low in winter, a controlled temperature cold storage is needed.
The method of natural cold treatment: bury the flowerpot in the soil and cover the bud with about 5 cm of soil.
Frost prevention: natural cold treatment of flowerpots buried in the soil must be in good contact with the soil and cover the surface with a layer of straw (at least 10 cm thick). Plastic or blister film should also be covered during frost, and then covered with extra straw. Remove plastic film and extra straw after the frost period.

Reproduction: commonly used ramet and sowing reproduction. Ramet, dig when the leaf or flower stem has just withered, separate the bulb. The depth of planting is 10 cm, and the depth of the bulb can be adjusted automatically with telescopic roots. Sow and reproduce, sow immediately after seed collection, sow in autumn to the following spring, young roots germinate and form.

Efficient cultivation techniques of rotation of ginger and spring onions
Ginger has a special spicy flavor because it contains gingerol, gingerone and gingerol, and it is a seasoning vegetable widely used by the people. at present, the annual sales volume of the whole country has exceeded 400000 tons, and the export momentum is very good; green onion is a tonnage vegetable exported to Japan in China. it is of great practical significance to study the efficient cultivation techniques of these two kinds of vegetables. After years of exploration and research, we have come to a set of efficient rotation technology. 1 early ripening cultivation techniques of ginger in greenhouse (previous) 1.1 Variety selection
