Onion planting time and method

Onion is one of China's traditional vegetables and is widely grown in various places. It is not very demanding on soil, but fertile, loose, well-drained loam or sandy loam is preferred. Below, the editor will introduce the time and method of planting onions, let’s take a look.

1. Onion planting time

1. Spring planting

It is usually between March and April, but it can be postponed to mid-to-late April in the northern region, and advanced to early or mid-March in the southern region. The temperature gradually rises in spring and the soil begins to thaw, which is conducive to the germination and growth of onions.

2. Summer planting

It is usually carried out between June and July, but it should be noted that a high temperature and high humidity environment is not conducive to the growth and quality formation of onions. Onions planted in summer need special attention to water management and disease and pest control to ensure the healthy growth of the onion plants.

3. Autumn planting

Usually between August and October, it is one of the main seasons for onion cultivation. The temperature in autumn is moderate and there is less rainfall, which is conducive to the development of the onion's root system and the growth of the onion's white part.

2. Onion planting method

1. Soil selection

Choose deep, well-drained, fertile and loose soil for planting. After deep plowing and land preparation, apply appropriate fertilizer according to soil fertility to provide adequate nutrition.

2. Seed selection

Choose healthy, disease- and insect-free onion seeds for sowing or transplanting. The seeds can be soaked for 2-4 hours in advance to promote germination.

3. Sowing and seedling raising

There are two methods of sowing: row sowing and spot sowing. When sowing in rows, the row spacing is kept at 30-40 cm, the hole spacing is about 10-15 cm, and 2-3 seeds can be sown in each hole. For spot seeding, seeds are directly sown on the plot and covered with about 1-2 cm of soil. Keep the soil moist after sowing, especially in the early growth stages, and avoid drought and waterlogging. If the seedling method is adopted, the seedlings can be raised in a warm environment after sowing, and transplanted after the seedlings grow to 10 cm in height.

4. Field management

Strengthen fertilizer and water management, and apply nitrogen, phosphorus and potassium compound fertilizers in a timely manner according to the growth needs of onions. Weed regularly to prevent weeds from competing for nutrients. Check the growth status of onions regularly, detect and deal with diseases and pests in time. Biological control or low-toxic pesticides can be used for prevention and control.

The above is an introduction to the time and method of planting onions. Onions have a short growth cycle and can generally be harvested about 3-4 months after sowing when the leaves grow taller and the stems become thicker. The fruits can be picked one by one as needed or harvested all at once.
