If you want to plant green onions for high yield, how to manage green onions to achieve high yields?

We all know that now for many farmers, they need to learn a lot of precautions when planting each crop, and now many people want to have high yield when planting green onions, but some people will have such questions, that is, how to manage the planting of green onions to achieve high yield? For this problem, in my opinion, the first thing should be reasonable fertilization, and the second is to prevent pests and diseases.

1 Proper fertilization

In our real life, in fact, when planting each kind of crop, we need to apply a certain fertilizer, because many times these plants are far from enough to absorb those nutrients from the land, so when we see that the leaves of these green onions are relatively yellow, we can reasonably apply a certain fertilizer to them. This can provide them with some nutrients for their growth.

2. Prevent pests and diseases

In the process of planting green onions, sometimes it is likely to suffer from this situation, this phenomenon is very common in our real life, so when we see such a phenomenon, we should promptly call a certain pesticide to the green onion, some pesticides themselves are to prevent and control the invasion of pests and diseases. For example, pesticides. These are some of the high-end technologies that are available today.

And it is also targeted to crops.

Therefore, in ordinary life, we should pay more attention to this aspect of the problem, for everyone, when we are planting these crops, we should observe some of his current situation, if there is any abnormal phenomenon, we should take some effective measures to prevent it in time. So as not to bring us certain economic losses, because in many cases, if there is such an invasion of pests and diseases, it is likely to lead to a reduction in yield, and will seriously affect his normal growth. That's it for some of my knowledge on this issue.

It is divided into three stages of management: the first stage is to apply enough fertilizer to the land during the period from picking onions to ambushing, so that the green onions can absorb nutrients well; The second stage is from mid-July to early August, when the prevention and control of insect diseases should be done; The third stage is the period from mid-August to mid-October, when proper topdressing is required and the corresponding fertilizer is sprayed, which can increase the yield.

During the planting period, you should do a good job in land management, and then during the planting period, you must pay attention to water and fertilizer management, water more water on the green onions, and apply more potassium fertilizer to it, so that the planted green onions will be particularly high-yielding.

Attention should be paid to the spacing of planting, and should also be timely watering and fertilization, strengthen the management of water and fertilizer, but also should choose organic fertilizer, and should also be timely loosening of the soil, to ensure that the soil is fertile and transparent, and should also be sprayed in time with some pesticides.

Be sure to fertilize more, and be sure to choose winter when planting, choosing nutrient-rich soils.

I would choose sandy soils. We will also pay attention to the pH value of the soil, try not to make the soil breathable, and apply it widely.

When planting green onions, we should talk about those dead seedlings, sick and weak seedlings, etc., to avoid consuming too many nutrients, the planting depth of green onions should not be too shallow but not too deep, and then one is the problem of planting density needs to grasp the scale. Soil is the key to the healthy growth of green onions. We need to choose a suitable soil before planting.

Ensuring that the soil is thick and soft, rich in organic matter, and good moisture can ensure the healthy growth of green onions, which is of obvious help to improve its yield. Pest control is very important for most crops, and if you don't do it properly, it can lead to a bad green onion harvest. Therefore, we must pay more attention to the prevention of pests and diseases on weekdays, and carry out prevention and control in a timely manner according to the specific situation.

That's how I grow green onions.

It is best to choose sandy soil, which should be very fertile, and should be watered in time to ensure the moisture of the soil.

In the last argument about four weeks before the frost, you can plant the seeds or bulbs, if it is a seed, the depth of sowing is centimeters, the distance between columns is about 30 centimeters, if it is a bulb, the roots are planted, the distance between each other is 5 centimeters, the depth is centimeters, the edible part of the green onion is fat green onion white and young leaves. Green onion seedlings should be raised before planting, and the seedling land should be selected with loose soil, rich organic matter, flat terrain and convenient sandy soil, and the ground should be turned deep and whitened before seedlings, which can kill some germs and insect eggs.

For four-season cultivation, choose cold-tolerant, drought-tolerant, heat-resistant, adaptable, long, and non-tillering varieties, such as Chinese giant onion, Zhangqiu green onion (tall leg white) or local farm varieties whip scallion. Onion varieties are not suitable for cultivation in four seasons. Digging and planting ditches:

Generally, the depth of the ditching stool is the height of green onion white - the height of soil cultivation - 1 4 green onion white height. 1 4 The height of green onion white is the white part of the green onion above the soil to below the five prongs of the green onion leaves. Before ditching, it is necessary to first understand the general white height of the selected green onion varieties.

After the planting ditch is excavated, apply well-rotted organic fertilizer and fast-acting fertilizer at the bottom of the ditch, and loosen the bottom soil of the ditch to fully mix the soil with fertilizer. Planting: Before seedling, moisten the surface of the seedbed with an appropriate amount of water.

Pull up the seedlings, shake the soil, and remove the diseased and weak plants. The cultivation method is generally sown from January to March, and the way used is the way of sowing, and then it can be marketed in May, if it is sown in March, then it can be marketed in June, and it can also be transplanted in June.

Select the type of green onion you want to plant. Onions or shallots are some green seedlings that appear before the shallots form. They are extremely immature green onions.

Look for heart-shaped green onion seeds, such as shallots, or simply choose your preferred white, red or yellow shallots to grow up in deep soil, the deeper the soil, the longer the shallots will be whiter and the straighter the shallots. Another point is that after the onion sprouts and grows, it must be transplanted. Such onions are strong and not easy to attract diseases and insects.

Planting green onions should be planted in the soil with strong fertility, and the drainage should be good enough, and then add nitrogen fertilizer every day, and water at night, so that the green onions can grow well.

During the planting process, you should pay attention to the surrounding environment, maintain the temperature and humidity of the soil, and pay attention to watering more often.

Usually, green onions are still very good to survive, so there is no need for additional management, apply some fertilizer to the eggplant regularly, and remember to replenish water.

1.Autumn planting timeIt is planted in early to mid-September in the autumn of the first year, and planted in early to mid-May of the following summer, so it can be obtained before winter and can be cultivated in kilns or in the open field.

Generally in the early spring planting, and to carry out after the soil thaws, it can be used as a green onion supply before the arrival of the hot summer, after the green onion is planted, you can choose the dry onion or furrow onion obtained at the beginning, and can also be used as a wintering horn onion or seed plant.

It is mostly planted from mid to late July to early to mid-August, so it is also called Fu onion. At the beginning of wintering, the main stem is relatively large. It is easy to carry out the whole process of vernalization, it sprouts early in the next spring, and can quickly sprout and flower, so it is generally sold after the horn onion.

As a green onion planted in all seasons, it is best to choose a cold tolerant one. Drought. High temperature resistance. Adaptable. The green onion root is long. Species that do not tassel, such as Chinese giant onions. Zhangqiu green onion (high leg white) or regional farmhouse variety whip green onion.

1.Plough early, plant early

Reasonable dense planting is an important experience gained from many years of planting, and the production of early planting of onions is significantly higher than that of late planting. In addition, reasonable dense planting is the key countermeasure for high-quality and stable yield of green onions, and the general plant spacing is 4 6 cm, and the row spacing is 25 30 cm.

2.Soil weeding should be done immediately

Prevent root rot caused by waterlogging and improve the aeration of the soil, and the shallot is planted at a time when the temperature is high. When there is a lot of precipitation, there are many kinds of wild grasses, so we must hoe the grass immediately to avoid grass shortage; The moon is the period of concentrated precipitation in the north, which is easy to cause shallots to soak. Scorch.

In addition to doing a good job in draining and storing water, it is also necessary to break the surface moisture early, so that the rhizomes of shallots can carry out a variety of normal theme activities.

3.Base fertilizer topdressing should be appropriate

Generally, the first fertilizer is carried out after the cold dew, according to the conventional fertilizer situation, about 2000kg of fertilizer is needed for 1 mu, or 200kg of peanut bran, plus 20kg of urea solution. Until the second fertilization is carried out after the summer heat, about 15 kg of urea solution is required for this fertilizer.

In the end, it is to look at the growth of green onions, if the leaves of green onions are thinner, and there are more mixed barbs, then we must also top dressing appropriate potassium fertilizer. Moreover, in each growth of the green onion, I add chemical fertilizer appropriately and fill the nutrients needed for the growth of green onion.

The main reason is that we growers are using phosphorus at the wrong time. Green onions are very sensitive to phosphorus, so the best time for us to use phosphate fertilizer is the stunt of green onions, that is, the seedling period of green onions. In this period, the roots of green onions are particularly developed in the future, which can effectively improve the cold resistance of green onion plants in the later period, promote the early maturity of green onions, and increase the yield and commerciality of green onions is eye-catching.

If the green onion stunt lacks the use of phosphate fertilizer, and the phosphate fertilizer is supplemented after the green onion transplantation, it is actually too late, and the yield of green onion has been greatly affected. Now that growers who plant green onions in autumn have started planting seedlings, this is the best time to use phosphate fertilizer.

In fertilizer, it is necessary to ensure the balance and sufficiency of various mineral nutrients, and secondly, according to the characteristics of nutrient demand at each growth stage, targeted fertilization should be applied to meet the fertilizer preferences of plant growth. According to the growth law of green onions, there are four most prominent fertilizers for high-yield and high-quality cultivation of green onions, which also have the greatest impact on the quality and yield of the final product of green onions once the supply exceeds demand. The basic fertilizer is the basic support of nutrients in the growth process of green onions, is an important source of nitrogen, phosphorus and potassium, and is the main source of medium and trace elements.

In the composition of basic fertilizer, the main fertilizer is fully rotten, the yield of green onions is high, and the use of farmhouse fertilizer should also be increased accordingly, the appropriate amount per mu is 4000-5000 kg, the role of farmhouse fertilizer in addition to improving the performance of soil structure, can also ensure the balance of various essential nutrients in the growth process of green onions, and prevent deficiency. In addition to organic fertilizer, the plot with appropriate soil fertility should also be sprayed with about 35 kg of calcium phosphate per mu, and the superphosphate can be effectively used, and can be sprayed together after mixing with organic fertilizer, so as to improve the utilization rate of the effect is obvious. In addition, the basic fertilizer needs to add an appropriate amount of potassium fertilizer, and potassium fertilizer can be applied with 150-200 kg of plant ash rich in sugar and potassium carbonate or 20-25 kg of potassium sulfate.

In addition, green onions are sensitive to boron deficiency. If the availability of boron is insufficient, the leaves will narrow, affecting photosynthetic capacity and reducing yield and quality, so kilograms of borax can be applied to the base fertilizer. The amount of borax should not be too large.

Otherwise, it is easy to be toxic to the roots of green onions.

Green onions are a sensitive period for the demand for personnel costs. Because the speed of the sapling after the green onion is planted, the growth rate after the sapling is directly related to the growth and absorption capacity of the root. Phosphate fertilizer can promote the growth and function of green onion roots.

Green onions are understaffed in the seedling stage, the roots of the seedlings are not good, the growth is slow, and the micro-resistance of the plant decreases, so the seedling of green onions ends.

What fertilizer is good for green onion fertilization? How to fertilize green onions for high yield?

When the green onion seedlings are small, some phosphorus fertilizer and nitrogen fertilizer should be applied, and after growing taller, compound fertilizer can be applied and watered frequently, and the green onions that grow are particularly tall and particularly stout.

When planting, it is necessary to choose appropriate fertilizers, and organic fertilizers and compound fertilizers should also be chosen, and fertilizers should also be applied in a certain proportion, and they should also be watered in time.

Top dressing during the growth period.

In the growth stage of green onions, timely topdressing can meet the needs of green onion growth and development, which is important to obtain high yield and high quality of green onions.

Measure. In the different growth stages of green onions, the demand for nutrients is also different, and topdressing should be carried out in combination with different stages.
