Nowadays, people are increasingly demanding vegetables. When there are vegetables in the off-season, growers will find a way, but in the autumn, they grow green onions and the weather is very unstable. Therefore, the cultivation process is carried out. There is a need to strengthen management of the field so that higher yields can be achieved, and more attention is required in the selection of seedlings and soil.
Because it is a critical period for the formation of scallion at this time, and it has a close relationship with the surrounding environment. Therefore, if you want to improve the quality of green onions, then management in these areas needs to be more important.
1, watering
After the green onion is planted, it enters the high temperature season. At this time, it is necessary to control the amount of watering the green onions. Although it is after the rain, the weather is still hot, and the evaporation of water at this time is more serious.
If the watering is more frequent after the rain, it will cause the roots of the green onions to rot, and yellow leaves and dead seedlings will appear. However, if watering is not carried out in time, there will be drought and there is no way to ensure the growth of their normal roots.
Therefore, before the beginning of autumn, we must ensure that the water source is sufficient, so that we can get better nutrients. Then wait until it is basically long-formed and then gradually reduce the supply of water. At this time, it is only necessary to ensure the wetness of the soil and water. Wait until the real harvest, stop watering in a week or so, in order to ensure that after the harvest of green onions in the future, it will be more durable in the process of transportation.
2, top dressing
In addition to fertilizing at the beginning of planting, it is necessary to carry out regular topdressing in the future so that it can grow faster. In general, it is more effective to increase the foliar fertilizer, but in general, this fertilizer does not require any skill. Therefore, it can be implemented at any time during the later management.
3, soil
This operation is mainly to soften the sheath and also prevent lodging. Everyone knows that if Cong is doing planting, the soil is not so good and hard, it will lead to lodgings in the future, which will not only affect his harvest. Moreover, the quality of the rush will not be very good, so that it will not have high sales in the market, and it will affect its own consumption.
Therefore, it is necessary to do a good job of soiling, and the height is generally about 3 or 4 cm when its pseudo stem grows. Then, the soil is poured out to the outlet of the uppermost blade, so that not only the leaf core is buried, but also the leaf is prevented from decaying. It will be of great help to future production.
Vegetable growers want to plant green onions in the fall. It is necessary to pay attention to the above three aspects. For the selection of soil and onion seedlings, it is also necessary to ensure that the green onions are adequately fertilized.
