Is it possible to plant wheat in a large area and only use controlled fertilization without top dres

If wheat, only use controlled fertilization yield will be reduced, wheat planting to hoe, fertilization, spraying, later observation of wheat growth, additional fertilizer, to ensure the yield and quality of wheat!

No, if you don't top dress, the later growth will not be good, and the harvest will not be good.

I don't think so, because growing crops is to increase yields, and without topdressing, crop yields will be greatly reduced, and the gains outweigh the losses.

No. Moreover, this method of fertilization is also very incorrect, and it will also affect the problem of yield.

Summary. It is not right to apply only plantar fertilizer without topdressing. In the previous year, wheat development will consume a lot of nutrients, excessive base fertilizer will cause wheat seedlings to grow, and in the later stage, no top dressing will make wheat seriously lack of fertilizer, so the final wheat yield must be low.

This practice only saves labor, but the fertilizer is not used less, and it will reduce the yield of wheat, at least not increase it. First, it is easy to cause frost damage due to vigorous growth in the previous year, and second, there is a serious nitrogen deficiency in the later stage of wheat growth, which will definitely affect the final yield.

Hello, I have seen your question and am sorting out the answer, please wait a moment No. It is not right to apply only plantar fertilizer without topdressing.

It's okay to read it wrong.

Didn't use base fertilizer in the early stage.

You can also add more fertilizer later.

Summary. Dear, I'm honored to have your question The information that the teacher found for you here is: wheat sowing plus phosphorus and potassium fertilizer does not need to increase the sowing amount:

Wheat sowing with phosphorus and potassium fertilizers does not need to increase the sowing amount. Seed dressing method (1) dry mixing: put the sample powder in the seed dresser or other utensils, and then stir the seeds upside down and evenly.

2) Wet mixing: dilute the seed dressing agent into liquid medicine or fertilizer solution with water in a certain proportion, and then spray the liquid medicine or fertilizer solution on the seeds, use a shovel to stir it evenly, so that the surface of the seeds is evenly covered with a layer of film or fertilizer, and then the seeds can be sown after drying.

Summary. Hello, I have helped you find the result; Sufficient use of wheat base fertilizer can reduce the need for top dressing, but it cannot completely replace top dressing. The base fertilizer is mainly to provide the nutrients required in the early stage of wheat growth, while the top dressing is to meet the nutrient needs of wheat in the later stage of growth.

Therefore, if the base fertilizer is used sufficiently, the frequency and amount of top dressing can be reduced, but the appropriate amount of top dressing is still required according to the growth of wheat. I hope I can help you and wish you a happy life <>

Dear, hello has helped you to inquire about the results of Chang Shi; Sufficient use of wheat base fertilizer can reduce the need for top dressing, but it cannot completely replace top dressing. The base fertilizer is mainly to provide the nutrients required in the early stage of wheat growth, while the top dressing is to meet the nutrient needs of wheat in the later stage of growth. Therefore, it is resistant to slag, and if the base fertilizer is used sufficiently, the frequency and amount of top dressing can be reduced, but it is still necessary to carry out the appropriate amount of top dressing according to the growth of wheat.

Is it okay to apply enough low fertilizer for wheat and spray foliar nitrogen fertilizer in the later stage?

Hello, I have helped you find the result; OK. Wheat needs nutrients at different stages during growth and development. The application of low fertilizer can provide the nutrients required for the early growth of wheat, while the application of foliar nitrogen fertilizer can provide the nitrogen required for the later growth of wheat, promote grain filling and residue tolerance, and improve yield and quality.

However, it should be noted that the concentration of foliar nitrogen fertilizer should not be too high to avoid burns and leaves. At the same time, it is also necessary to fertilize scientifically and reasonably according to the specific growth situation and soil conditions. I hope I can help you and wish you a happy life <>

Summary. In two months, wheat has undergone earth-shaking changes, and by topdressing wheat, three effects can be achieved: balanced nutrition.

Wheat has different nutrient requirements at different growth stages, and wheat has a large demand for nitrogen before winter, resulting in a decrease in the proportion of nitrogen in the soil. By applying fertilizer in spring, the nitrogen in the soil can be replenished, and the nitrogen fertilizer demand of wheat can be guaranteed at the jointing and heading stage. Help the weak and promote the strong.

Before winter, field management, water and fertilizer management, disease management are not in place or suffer from frost damage, resulting in sluggish growth of wheat, and the problem of weak seedlings and yellow seedlings is prominent. By applying fertilizer in spring, the growth of weak seedlings can be improved, so that weak seedlings become normal seedlings, and normal seedlings grow vigorously. Increase the number of spikes.

The growth rate of wheat in spring is fast, the nutrients required are large, and the nutrients are not timely, and the tillering, the number of ears and the number of grains of wheat will decline. Through spring topdressing, wheat tillering can be promoted, and the number of spikes and grains per spike per unit area can be increased.

Can wheat be topdressed now.

I'll send you the answer right away.

Wheat can now be topdressed by pro-kisses.

Spring is the critical period for wheat growth, and top dressing can be used for regreening, rising and jointing. From mid to late February to early March, wheat turns from yellow to green for new clothes, which is regarded as returning to green; From mid-March to early April, the wheat is seen as rising from prostrate to erect; From early April to mid-April, wheat jointing is upward, which is regarded as jointing.

In two months, wheat has undergone earth-shaking changes, and by topdressing wheat, three effects can be achieved: balanced nutrition. Wheat has different nutrient requirements at different growth stages, and wheat has a large demand for nitrogen before winter, resulting in a decrease in the proportion of nitrogen in the soil.

By applying fertilizer in spring, the nitrogen in the soil can be replenished, and the nitrogen fertilizer demand of wheat can be guaranteed at the jointing and heading stage. Help the weak and promote the strong. Before winter, field management, water and fertilizer management, disease management are not in place or suffer from frost damage, resulting in sluggish growth of wheat, and the problem of weak seedlings and yellow seedlings is prominent.

By applying fertilizer in spring, the growth of weak seedlings can be improved, so that weak seedlings become normal seedlings, and normal seedlings grow vigorously. Increase the number of spikes. The growth rate of wheat in spring is fast, the nutrients required are large, and the nutrients are not timely, and the tillering, the number of ears and the number of grains of wheat will decline.

Through spring topdressing, wheat tillering can be promoted, and the number of spikes and grains per spike per unit area can be increased.

You can grow wheat without chemical fertilizers, and you can make your own farm manure.

The process of making manure is as follows:

In autumn, the corn stalks are cut into small pieces and then piled up in a warp and weft shape in the order of upper and lower levels.

Pouring feces and urine on it must achieve the effect of making it soak for a long time.

It is then allowed to ferment, or it can be added to the potash-rich plant ash or charcoal after burning.

In the spring of the following year, it will be dried into small pieces of gray-black fertilizer or gray-black fertilizer water with water quality, which is manure;

Wheat straw stacks can also be used to make manure.

In the process of manure making, the stems, vines, and leaves of other plants or the branches of dead trees picked up by cleaning the garden are always added to the straw stack.

What should I do with this question?? If you don't pursue yield and the soil is very fertile, you can do without chemical fertilizers, but China's agriculture is basically predatory production, do not pay attention to nutrient return, the soil will be poorer, it is easy to desertify over time, and the yield is decreasing year by year, personal advice is not only to use chemical fertilizers, but also to use organic fertilizers, farm fertilizers. --Shi Kefeng, Ministry of Agrochemistry, Wang Military Commission.

Yes, yes, but the yield will be very low!

First, top dressing and protection of sin Late sowing wheat seedlings in the three-leaf dew, to promote the formation of early sins, strive for 4 leaves not vacant, to protect the survival of tillers. Therefore, it is necessary to apply seedling and tillering fertilizer in advance, apply 5 kg of urea per mu of wheat field after seedlings are ready, and spray 800 times of new high-fat film in a timely manner to improve the utilization rate of active ingredients in fertilizer.

2. Anti-freezing and seedling protection Late-sown wheat has few overwintering leaves, and the secondary roots form an independent system, which is susceptible to frost damage. Apply wax fertilizer early. Before December 31, combined with weeding and loosening soil roots, apply about 50 quintals of soil and miscellaneous fertilizer per mu of wheat field to protect the tillering joints.

Third, the central control of the prevention of late sowing wheat in spring is fast, and the leaf emergence speed is faster in the case of sufficient fertilizer and water. From the rejuvenation stage to the basal internode elongation period, lightly press 1 time with a wooden stool to control the tillering after spring, promote the tillers into ears, and the jointing fertilizer should be timely and appropriate, and a certain amount of phosphorus and potassium fertilizer should be applied, and the amount of urea applied per mu of wheat field should not exceed kilograms.

Fourth, spraying phosphorus and strengthening grains Foliar spraying of phosphorus fertilizer can improve the seed setting rate of late-sown wheat, and spray strong panicle spirit at the booting stage of wheat to strengthen the physiological function of crops, improve the quality of pollination, fertilization and grain filling, and increase the weight of 1000 grains. At the same time, before and after heading, 2 3 times of potassium dihydrogen phosphate solution plus 800 times of new high-lipid film were sprayed continuously, with an interval of about 5 days each time, which also had a good effect on improving yield.

1. Due to the long-term flooding of paddy fields, the soil is compacted and the permeability is poor, so it is necessary to promote soil maturation through water-dry rotation and alternating dry and wet. The characteristics of land preparation are that when the previous crop is harvested earlier, it should be ploughed as soon as possible during the suitable cultivation period, so as to take advantage of the high temperature and sunny weather in early autumn, and then carry out shallow tillage and fine raking before sowing in the kang soil, so as to achieve deep and soft and fine, and the top is virtual and the bottom is solid; In the past, as a late rice or hybrid rice farming, due to the short spacing between harvesting and sowing, the ditch should be opened and drained when the rice seeds are scattered, and strive to dry the thin slices and short-term kang fields; On the premise of not delaying the timely sowing of wheat, it can also be shallow rotation to create a good seedbed and growth base for wheat.

2. The land preparation of dryland wheat should be based on the basis of increasing the deep tillage layer year by year, combined with the application of organic fertilizer, and improving the retention and storage of water and fertilizer, and the land preparation should be carried out according to different forms of multiple cropping. That is, the previous harvest is earlier, such as spring corn, sorghum, tobacco, etc., the harvest should first be shallow tillage to eliminate stubble, and then deep ploughing of the kang soil, so that the residue rots and accepts the autumn rain, shallow rake after the rain, reduce evaporation; The other category, such as sweet potato, cotton, etc., has a tight harvest time, and if the conventional method is used, it is bound to delay the sowing date, which is one of the important reasons for the low yield of wheat in southwest China. Therefore, on the one hand, the implementation of loosening soil and moisture between the rows in the previous crop and later period, and then plowing and leveling when planting wheat; On the other hand, it advocates continuous operations such as digging potatoes, leveling the ground, fertilizing, and sowing to ensure that wheat is sown in a timely manner.

High-yield technology: 1. Pay attention to the selection of high-fertilizer and water plots. High-yield and high-quality wheat varieties require that soil nutrients must be comprehensive and sufficient to meet the needs of high-yield cultivation, so it is advisable to choose plots with high soil fertility and good watering conditions, increase organic fertilizer, and adopt formula fertilization technology.

Second, pay attention to the appropriate period of late sowing, according to the characteristics of the variety, to determine the appropriate basic seedlings. It is necessary to prevent excessive sowing volume, resulting in passive post-management.

3. Pay attention to prevent lodging and reapply the high-quality wheat varieties promoted by getting up and jointing, some are not resistant to lodging, especially for wheat fields with too large groups, a chemical control treatment must be carried out before returning to jointing, and paclobutrazol or wheat Yefeng can be sprayed. It is necessary to reapply jointing fertilizer to control the formation of excess falling ears and promote large ears and more grains.

Fourth, pay attention to watering grouting water, wheat water, spraying foliar fertilizer, to prevent premature aging. Watering the grouting water plays an important role in increasing the weight of the grain and preventing dry and hot air. In dry weather, the use of wheat water is conducive to intercropping and preventing premature aging.

In the first half of May, combined with the prevention and control of pests and diseases, spray 2 or 3 times of foliar fertilizer, such as potassium dihydrogen phosphate, which can reduce the harm of dry and hot air and increase yield.

Fifth, pay attention to the prevention and control of pests and diseases. Generally speaking, high-quality wheat is more susceptible to pests and diseases, such as wheat sheath blight and powdery mildew, and aphids occur earlier and heavier than conventional varieties. It should be prevented and treated as soon as possible according to the forecast.

6. Spray wheat treasure once when the wheat [just breaks, before heading and flowering] reaches about 60-70% (as shown in the figure below), activates the activity of biological enzymes in wheat, promotes the development and coordination of female and male organs, enhances the photosynthesis of functional leaves, significantly reduces the empty stubble rate, improves the seed setting rate and 1000-grain weight, so as to achieve the effect of increasing yield.

The n in this fertilizer is enough, there is no need to mix urea, to the spring of next year, if the seedlings are weak when watering, apply some urea, 10kg per mu.
