Onion planting methods and precautions, onion planting skills and management methods

There are two ways to plant green onions: seed seeding and seedling transplanting.

Sowing with seeds is around mid-September in autumn.

When sowing, it is necessary to plough the plot in advance and add bottom fertilizer before sowing. The seeds that are sown are not easy to be too dense.

The emergence time is about 7-10 days. Green onions sown in autumn can be sold in the following spring.

However, in my hometown, the green onion leaves are harvested once or twice in the spring, and then the seedlings are transplanted in the summer.

When transplanting, it can be transplanted by ridge or flat.

I think that ridge transplanting is more beneficial for the future growth of green onions.

Because the ridge transplanted green onion can grow a relatively long green onion white, and at the same time, it can be planted symmetrically on both sides of the ridge.

When transplanting, it is still the same as direct planting, the soil needs to be dug deeply, sorted out, and fertilized in advance to make the soil in a soft state, so that the transplanted green onions will be able to achieve the joy of a bumper harvest.

As for the precautions, it is necessary to turn the land deeply, and the additional base fertilizer is mainly farmhouse fertilizer, and only fertilization and chemical fertilizer can be applied if there is no farmhouse fertilizer. In my hometown, the fertilizers used for base fertilizer are diammonium, organic fertilizer, etc.

Secondly, it is the field management in the process of growth, timely hoeing, timely observation of pests and diseases, timely prevention of management measures and so on.

Qingying said Nongda.

Hydroponic chives need to be changed once a day, which can ensure that the growth environment of the plant is clean and tidy, and an appropriate amount of nutrient solution can be added to the water of breeding chives, which is conducive to the growth of chives, but pay attention to the concentration should not be too high, otherwise it will affect the growth of the plant.

Chives like cool climate, cold and heat resistance are strong, daily need to maintain it in the environment of 25 30, winter temperature is too low, plant growth will be affected, need to move it to a warm place for maintenance. Chives require moderate intensity under light conditions, and the tissue is easy to age, increase fiber, and deteriorate in quality under strong light conditions.

The best time to plant onions is in spring and autumn, and you need to choose flat land for planting. Onion management methods: water and fertilizer management, keep the soil moist, can be topdressed 1-2 times during harvesting; Soil management, soil cultivation and watering can be carried out with each other, which can speed up the growth rate of green onions; Pest control can be controlled with pesticides with low toxicity and low residue.

Onions are suitable for growing in a cool environment, and the best growing temperature is about 20 degrees, so the best planting time is spring and autumn. Choose fertile, deep, flat soil for planting, and the density is generally 1.5 million plants per hectare. The temperature is low and the germination is slower during spring sowing, so it is necessary to keep the soil moisture content sufficient and the surface not compacted.

1. Water and fertilizer management

The soil before and after the emergence of green onions should be kept moist and watered several times, with only a small amount of water each time. Watering should be controlled at the seedling stage and after transplanting, during which the soil should be loosened 1-2 times, and watered every other week in the later stage. In addition, if the harvest period is too long, it is necessary to sprinkle the rotted and puffed chicken manure into the field and top dressing 1-2 times.

2. Soil cultivation management

During the growth of green onions, soil cultivation and watering need to be carried out with each other. After watering, the soil becomes semi-dry, and it is necessary to pay attention to watering after soiling, which is conducive to improving the growth rate of green onions, and the higher and higher they rise, they can speed up the harvesting process.

3. Pest control

Onions are susceptible to downy mildew, purple spot, gray mold, etc., which can be effectively controlled by agricultural control and physical control. When the occurrence of pests and diseases is more serious, it is necessary to use low-toxicity and low-residue pesticides for prevention and control, and pesticide additives such as anti-resistance solution can be added to increase the propagation of leaves.

Spread the green onion seeds into the furrow at a distance of 5-8 cm, and cover the soil with water. 3. Field management: dig and build drainage ditches in the field in time during the rainy season.

4. Precautions: pay attention to controlling the humidity and temperature in the field, and spray chlorothalonil liquid immediately after the onion seedlings become ill.

1. Organize the plot

When planting green onions, you can choose a plot close to a water source, easy to drain and irrigate, rich in organic content, loose and breathable soil, and then plough it for 20 cm, remove weeds and crop residues in the soil, then break up the clods, and finally apply enough farm fertilizer.

2. Reasonable planting

The suitable planting time of green onions is generally in May and June every year, in the plot according to the distance of 30 cm per row of ditch, and then the seeds are sown into the ditch according to the distance of 5-8 cm plant, after sowing it is covered with fine soil, and watered enough.

3. Field management

After the onion planting is in the season of abundant rainfall, it is necessary to dig drainage ditches in the field in time, prepare for waterlogging and drainage, and carry out tillage immediately after heavy rain to avoid soil compaction, and apply 1-2 times of diluted manure water at the seedling stage.

4. Precautions

During the growth of green onions, it is easy to suffer from the threat of purple spot, onion rust and thrips, leaf miner flies and other pests and diseases.
