Onion cultivation techniques:

10 days before sowing, plough first, apply fully decomposed, mashed and sieved farmhouse fertilizer, the amount of fertilizer per mu does not exceed 2000kg, and then plough twice, about 20cm deep, so that the fertilizer and the soil are fully mixed, and then use a flat rake to level the furrow surface for sowing.

The transplanting period can be divided into: the suitable transplanting period for mulched fields is from November 15 to 20 (before and after the beginning of winter); The suitable transplanting period for fields without mulching is October 20 (before and after frost). The regular density should be increased or decreased accordingly according to the soil fertility, fertilization level and management level, and the general planting row spacing is 20cm, the plant spacing is 16 17cm, and the density per mu is 20,000 plants.

6.Firmly tamp the soil on top of the onion.

7.To maintain an onion burning orange field, use a hoe to cut off the tops of any weeds that appear.

If the moisture can not meet the requirements of seedling emergence after sowing, you can use a watering can to spray water to promote seedling emergence, or you can sow after germination. Soak seeds in cold water, the time is not more than 12 hours, wrap it in a damp cloth and place it in a cool place of 20 24 for germination, wash it with water once a day, and sow it in time when the seeds are just "exposed", if not sown in time, the growth of radicle will cause inconvenience to the work of sowing rubbers.

Autumn planted onion seedlings will enter the overwintering period after survival, and in order to ensure the safe wintering of planted onion seedlings, it is necessary to water wintering water in a timely manner. After wintering, it returns to green and enters the growth period of stems and leaves, and the requirements for water at this stage are not only watering to promote growth, but also to control watering to prevent growth. The method of controlling watering is called "squatting seedlings", squatting seedlings should be mastered according to weather conditions, soil properties such as roundness and growth conditions after planting, under general conditions, squatting seedlings for about 15 days.

When the outer leaves of the onion seedlings are dark green, the wax increases, the mesophyll becomes thicker, and the color of the heart leaves becomes darker, the squatting seedlings start to be watered. After that, water every 8 9 days to make the soil dry and wet, so as to promote the growth of plants and prevent the growth of plants. Watering should be stopped 7 to 8 days before harvesting.

Onions will bloom, and it contains a lot of nitrogen compounds, as well as phosphorus and potassium and other elements, can add a lot of nutrients to the flowers, generally in the spring in May or summer in July for flowering, the flowering time is relatively long, there should be sufficient sunlight during the maintenance period, when flowering, the inflorescence is umbrella-shaped, and there are a lot of buds, its pollen is generally white, there are about 5 petals, it is more beautiful.
