High-yielding planting techniques of spring onion

Scallion is a common root vegetable in people's home cooking. It can be seasoned in cooked dishes. It tastes delicious and is loved by the public. So, what are the high-yield cultivation techniques for shallots? Let's learn together!

I. Planting time

The suitable temperature for shallot is warm and cool climate, about 15-25 degrees is the best temperature, in North China generally divided into spring and autumn planting, spring is generally around Qingming, autumn planting is most suitable, other areas according to the climate to decide whether spring or autumn sowing, in addition, shallot cold resistance, can winter, so winter do not bother to manage.

II. Growth temperature

For shallot temperature as far as possible according to its growth habits, because shallot more like cold, so the appropriate temperature is basically 12 degrees to 22 degrees best, not too high temperature, because too high temperature will lead to shallot growth slow, so some farmers friends reflect, their own shallot is not long or long slow, there are a small number of factors are caused by temperature, summer time to pay attention to shade.

III. Watering skills

Appropriate watering can be carried out during the growth period of shallot. The watering amount should not be too large. Excessive watering will cause ponding phenomenon, which will lead to rot of shallot roots. Therefore, according to the characteristics of drought tolerance and waterlogging tolerance of shallot, proper watering can be carried out. In case of dry soil, proper watering can be carried out. It is not recommended to irrigate a large amount of water.

IV. Soil selection

The growth of shallot on the soil requirements are not harsh, shallot planting as long as the choice of fertile, loose, strong drainage, deep soil layer can be, for too alkaline soil to carry out acid-base neutralization before planting, because alkaline soil will affect the growth and development of shallot, soil PH value maintained at 6-7 is the most suitable shallot growth.

V. Fertilization management

In the seedling stage, phosphorus fertilizer should be supplemented in time, nitrogen and potassium fertilizer should be supplemented mainly in the growth stage, and then appropriate trace nutrients should be supplemented. In different growth stages, nitrogen, phosphorus and potassium fertilizer should be mainly used, and then combined with trace elements for fertilization, which is more conducive to the growth and yield of small onion.

VI. Harvest management

Shallots are vegetables that can be harvested like leeks. They can be harvested once every other month. It is necessary to pay attention here. Don't harvest them every 10 days because they can be harvested. Too short a time will lead to poor nutrition roots of shallots. It is better to harvest them once a month.

Seven, shallot fresh tips

Shallots are a kind of yang-loving vegetables. The more light and drought, the stronger the taste of shallots. On the contrary, less light and sufficient water will make the taste of shallots lighter and less spicy. Therefore, when the shallots are about to be harvested, you can reduce the light and keep the water, so that the shallots will be more tender and have a longer shelf life.

The above is the high-yield planting technology of shallot organized by the soil flow net, hoping to help you.
