The planting method of scallions

Scallion is a kind of special vegetable, which is widely distributed in northeast China. The growth period is about two months, and the onion has a very high nutritional value. Can be used for the treatment of insomnia, pharyngitis and other diseases, but also can drop three high, now in our country also has a larger planting area. So how to grow shallot exactly? The following editor will give you a brief introduction, let's have a look!

1. Soil preparation and sowing

First of all, we need to choose a suitable soil for planting, mainly fertile, soft and permeable soil. Then do a good job of soil preparation, the soil depth of about 30 cm, its flat fine rake, and then apply sufficient base fertilizer, mainly farm fertilizer, supplemented by compound fertilizer. The sowing time of scallions is generally after Ching Ming Festival, and the main sowing method is border cultivation. Do the border digging stem, control the planting density before planting. If it is ridge farming, then be sure to dig a good ridge first, the ridge distance should be kept around 60cm.

2. Scientific fertilization

The root distribution of scallion is relatively shallow, so its nutrient absorption capacity is not strong, and its drought tolerance is poor. Therefore, in the growth period of scallion, we should do a good job of topdressing, promote the growth of scallions, promote the development of bulbs, and provide adequate nutrition for the growth of scallions. We should do a good job of topdressing according to the growth stage of shallot. For example, in the seedling stage of scallions, ammonium sulfate and potassium sulfate are the main fertilizers. After speeding up the speed of sending leaves, the amount of fertilizer should be increased to improve the quality and yield of scallion.

3. Rational watering

After sowing onions, if there is more water content in the soil, then the soil temperature can be increased without watering. If the soil water content is low, then watering should be done according to the actual situation. However, we should pay attention to control the amount of water to avoid excessive moisture leading to retting roots and rotten seedlings. Then when the bulb part of the scallion expands, it is necessary to appropriately reduce the amount of water to make the seedlings squat, and the squatting time is generally about a week. Like topdressing, the watering amount and frequency should be adjusted reasonably according to the growth stage of shallot.

4. Pest control

The prevention and control of diseases and insect pests of scallions is also very important. The common diseases and pests in the growth process of scallions are downy mildew, onion thrips and so on. No matter what kind of diseases and insect pests, we should give priority to prevention, spray disinfection properly about a week after emergence, and should not be carried out on rainy days. Different insecticides are sprayed according to different diseases and insect pests, for example, downy mildew is mainly chlorothalonil, purple spot is agricultural streptomycin, and onion thrips are chiefly EC.

The above is a brief introduction to the planting method of scallion. The planting method of scallion is very simple, but it can not be managed extensively, otherwise it will have a certain impact on the yield and quality, so we must pay more attention to it. That's all for today's introduction. This article is for reference only. I hope it can help you all.
