Small onions are common spices of life, which are fragrances and onions that can be cultivated in four seasons, usually in spring. In modern times, many people in their homes grow a few basins of balconies and pick them up whenever they want. Here's to learn how and how to grow onions。
Timing of cultivation
(i) spring spring: cultivation in january, harvest in mid-april
(ii) summer: plantings were removed from late april to early june and harvests from may to late july。
(3) autumn: deplantation from august to late september, and listing from mid-september to november。
(4) winter: deplanted from october to november and collected from january to february。
Ii. Cultivation methods
1. Land block selection
Small onions have cold- and heat-resistant properties, and the land under cultivation is subject to choice of soil that will protect its fertility, as well as sandy soil, which must be drained。
Fertilizing the whole area
One acre needs 1,500 pounds of farm fat, and about 120 pounds of potassium nitrous phosphorus compound fat. Fertilizers are applied within 30 centimetres of the ground first, with more than 10 centimetres covered by the ploughing soil, and the whole soil is rotated, the land level is levelled and 1. 3 metres of wide seedbeds are constructed。
3. Choice of varieties
It is recommended to select a variety of purple or white flowers, which are rich and of high economic value. There are now sichuan onions and four-dimension onions。
Seed treatment
In general, 50 degrees of hot water is to be immersed for more than 20 minutes with constant mixing to avoid burns. This way we can disinfect the bacteria. After cleaning up, you can sow. You can't rush it. As long as the temperature is suitable to germinate。
Seed density
The pre-plant beds are soaked with water and then the seeds are distributed directly, and a square metre bed is used to sow 6 grams of seeds, which can also be spread less, if appropriate. Seeds are thin, so they are covered under 1 cm and do not affect seedlings。
6. Management of plantations
The seedlings are then selected to pick out the weak and underdeveloped seedlings and then cut the roots and plant the field from 8 to 10 centimetres to 15 to 20 centimetres and the caves from about 3 to 4 centimetres deep。
7. Fertilizer management
After planting, water is poured on a daily basis to ensure the survival of the seedlings, and some roots will occur in about a week, allowing the water to be poured over three days to encourage the seedlings to take root. For about half a month, the slow-growing seedlings are normal, and the roots are normal, so that the soil can be dry and watered, sometimes. Fertilizer recovery takes place once a month after planting and is combined with water application and can be followed up once a month later。
