Planting conditions of scalloped head

Allium chinense is a kind of onion plant. Generally, the rootstock skin is red or white. In addition to fresh food, it can also be pickled and eaten. At present, it is mainly planted in the Yangtze River Basin. Widely cultivated in southern regions. It can grow well in cold climates, but it cannot grow in cold or hot climates. The specific requirements for teammates 'growth environment will be described in detail next. Help us understand the requirements of the living environment.

I. Temperature

It grows at temperatures above 5 degrees below 30-degrees, grows slowly at 30 degrees, stops growing above 30 degrees, and then slows down at temperatures below 10 degrees and above 5 degrees, and dormancy occurs below 5 degrees. Therefore, it is suitable for planting in the spring and autumn of the southern subtropical region, when the temperature is more suitable. The optimum temperature for growth is 15 to 21 degrees.

II. Light

It grows well in short days, can adapt to weak light, strong light is easy to lose water and heat burns, so it does not adapt to strong light, but long days can also grow, and the requirements for light are not strict. Warm sunshine and light hours in spring and autumn are the best light.

III. Humidity

Allium chinense does not need too much water, as long as it keeps the stems and leaves standing upright on the ground and the water supply of underground rhizomes can be sustained. Therefore, the soil humidity is generally maintained at about 55%, and the air humidity is maintained at 60%. General requirements to water less before germination, to avoid seed stem rot, germination should start watering, once a day. When the seedlings grow to 10 cm, water them once a month. Water can be watered once a week during rhizome expansion and less before harvest.

IV. Soil nutrition

It is required to choose fertile soil, preferably soil with high humus content. The soil is required to maintain a good structural layer, good drainage and ventilation, and if it is wind-proof and sunny sandy loam. Before planting, you can apply some humus soil to improve the soil. Then, you should apply a lot of base fertilizer, 1000 jin compost or manure per mu. Do not use poultry manure. Poultry manure is hot and has a long decomposition time. Farm manure can meet the demand for macroelements, as well as the demand for a variety of trace elements. In addition, various trace element fertilizers should be sprayed during topdressing. There are also different amounts of compound fertilizer at various stages.

For these environmental factors necessary for plant growth, Allium chinense has its own unique needs, such as its preference for fertilizer, may need adequate supply when growing and supplementing nutrients, in short, according to its growth needs to make appropriate adjustments to these environmental components. A good growth environment can be met for Allium chinense.
