Green onions, as a common vegetable in people's daily diet, are not only rich in nutritional value, but also have a wide range of application value. It stands tall in the mountains and fields, with green leaves like jade, white stems like silver, and a beautiful posture; Lying on the kitchen board, willing to add color and flavor to the dishes, the aroma is overflowing. With the rapid development of China's economy and the improvement of people's living standards, the green onion consumer market is becoming increasingly huge, the demand is increasing year by year, and the planting area of green onion is also expanding, becoming a pillar industry in some areas.
Although compared with the past, the current green onion planting technology has been greatly improved, and the yield area has also been significantly improved, but in the actual planting process, due to the lack of water and fertilizer management, the existence of diseases and pests, etc., still restricts the improvement of commodity attributes. In order to solve these problems, the scientific and efficient planting methods of green onions will be introduced from the aspects of environmental requirements, seed selection and planting, water and fertilizer management, pest management, and harvest management of green onions, so as to achieve the goal of high yield and high quality.
We need to understand the environmental requirements of green onions. Temperature is one of the important factors affecting the growth of green onions. Generally speaking, the temperature range of green onion germination is 2-20, and the higher the temperature, the faster the germination speed of green onion seeds; The suitable temperature for plant growth is 12-25. In addition, green onions have a strong ability to withstand cold and survive at low temperatures.
The soil also has a great influence on the growth of green onions. Green onions are adaptable and can be grown in most soils, but due to the weak ability of their roots to absorb water and nutrients, they need to be planted in fertile soils with loose soil, good drainage and irrigation conditions, and rich in organic matter. At the same time, it is necessary to avoid planting on land that is too clayey and poor, and where green onions are planted continuously.
Light and moisture are also important conditions that affect the growth of green onions. Green onions do not have high requirements for light, and normal natural light can meet their growth needs; However, when the light is too strong, it will cause the green onion leaves to age severely, and the light intensity can be adjusted by building a shade net. In addition, green onions love moisture and are not tolerant to waterlogging, so when the soil is too dry, it is necessary to water in time to keep it moist; In the event of continuous rainfall, it is necessary to open a ditch and drain the water in time to avoid the root rot caused by the rainwater soaking of the green onions.
Seed selection and planting is a key step in the process of green onion planting. When selecting green onion varieties, priority should be given to varieties with strong stress resistance, disease resistance, and ability to adapt to the local environment. When introducing new varieties, it is necessary to conduct trial varieties before expanding the scale. The selection of sowing time should be reasonably arranged in combination with the actual local situation.
Water and fertilizer management is an important part of ensuring the high yield and quality of green onions. When watering, it is necessary to flexibly grasp the actual situation and do a good job in drainage and irrigation; When fertilizing, we should pay attention to the application of basal fertilizer and top dressing according to the situation; At the same time, it should be coordinated with water and fertilizer management and soil cultivation.
Pest management is one of the key links to ensure the yield and quality of green onions. There are many kinds of diseases of green onions, such as downy mildew, soft rot, yellow dwarf disease, etc.; Pests include allium thrips, beet leaf moths, etc. It is necessary to take different control measures for different pests and diseases; Otherwise, once the pests and diseases become serious, it will cause serious consequences such as yield decline and quality decline.
Finally, there is the harvest management link. When the length of the green onion is more than 30 cm and the stem thickness is about 2 cm, it is ready to be harvested. In the process of harvesting, it is necessary to pay attention to the principle of light digging and deep planing; hierarchical management of harvested green onions; Pay attention to market demand in a timely manner and establish a combination of online and offline sales channels; Pay attention to maintaining a large customer base to avoid the emergence of unsalable.
In order to achieve the goal of high yield and high quality of green onions, it is necessary to start from the details and comprehensively manage each link; Only in this way can a satisfactory outcome be ensured in the end. Of course, sales work is equally important, because no matter how high the quality of the product is, there is no good economic profit without a smooth sales channel.
