Do winter wheat fields need to be fertilized? What is the best base fertilizer?

Some people say that the bottom fertilizer immediately with compound fertilizer can be, and some people propose the application of diamine, because the actual effect of compound fertilizer is not very good, compound fertilizer, compound fertilizer itself is very common, more than 2 nitric oxide synthase can be called compound fertilizer, but in the specific planting process, we often say that compound fertilizer has nitrogen, phosphorus and potassium, and now the content of compound fertilizer on the market is many. For example, the nitrogen, phosphorus and potassium content is the same, each with 15 or 18, and the content is also different.

Many farmers choose the same amount of compound fertilizer as the base fertilizer for wheat, with a total content of 45 (15 for nitrogen, phosphorus and potassium), but it is better to prepare it effectively. Generally speaking, the ratio of high nitrogen and low potassium depends on the condition of each land, and since many investors do not have professional testing equipment, the most effective decision is based on the specific situation of each land. In addition, the land that uses compound fertilizer, if there is a standard, it is best to integrate the application of organic fertilizer, without this standard, it is impossible.

How about diamine for wheat base fertilizer? Diamine is what everyone calls calcium phosphate diamine. Compound fertilizer with two factors of nitrate and nitrogen (also a type of compound fertilizer).

At this point, if the bottom fertilizer can not only rely on diamine, must be potassium fertilizer, you can choose ammonium sulfate, diamine also has nitrogen, but the content is too small, you must add some medical ether, so you don't need compound fertilizer, therefore, in the process of wheat growth and development, nitrogen, phosphorus, potassium three water-soluble fertilizers are indispensable. The base fertilizer is best compound fertilizer. Ammonium is not unusable, but it can be used in conjunction with other chemical fertilizers.

According to strict regulations, this type of ammonium is in fact a compound fertilizer. Due to the specification of compound fertilizers is more common. The compound fertilizer not only includes three elemental compound fertilizers, two elemental compound fertilizers, and in fact belongs to compound fertilizers, but farmers subconsciously call the three elemental compound fertilizers compound fertilizers in specific planting, which has established a correlation, but the actual practical significance needs to be understood.

Nowadays, there are many types of compound fertilizers on the market, including compound fertilizers that can be used for various crops, and there are also special compound fertilizers for wheat, which can be roughly divided into two types. First, compound fertilizers with the same nitrogen, phosphorus and potassium content, such as 3 compound fertilizers with 15 total content and 45 total content, or 3 compound fertilizers with 16 compound fertilizers with total content of 48 and 18 with a total content of 54.

To plant wheat, on the basis of deep ploughing and fertilization, it is necessary to harrow and level the soil, harrow the land to make the large soil clods smaller, and cultivate the soil to make the soil clods broken. Studies have shown that the effect of applying about 10,000 kg of farm fertilizer will be better if the field with a yield of 800 kg per mu is generally used. In order to eliminate underground pests (grubs, needleworms, ground tigers, etc.), soil disinfection can be carried out in combination with land preparation, and methyl powder is generally applied 2 3 kg per mu.

The land preparation of dryland wheat should be based on the basis of increasing the deep ploughing 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 multiple cropping forms. 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.

Wheat fertilizer requirements: fertilizer should be used general-purpose or low-nitrogen and high-phosphorus compound fertilizer 60-80 kg. According to this principle, urea, diammonium and potassium fertilizers can also be applied. 20-30 kg of urea should be added to the field where the straw is returned to the field to speed up the decay of the straw.

Need; It is best to use the three elements of nitrogen, phosphorus and potassium, and such a base fertilizer is the best, because it is an organic fertilizer, which can effectively increase the yield of winter wheat.

Yes, it is necessary to apply plantar fertilizer; Generally speaking, organic fertilizer can be chosen, but it must have nitrogen, phosphorus and potassium.

Yes, it is necessary to apply plantar fertilizer at the time of this winter wheat; You can choose the most basic base fertilizer, which can meet the nutrients required by wheat.

If you need base fertilizer, you should use farmhouse fertilizer with compound fertilizer, the ratio of the two fertilizers is five to one, sprinkle them on the surface of the land, turn the land deeply, and then plant wheat.

Wheat is divided into several knots such as returning to green, jointing, flowering, filling, and maturity in the life of wheat, first apply plantar fertilizer, three fifteen compound fertilizer plus organic fertilizer or add soil miscellaneous fertilizer more than 2000 kilograms, return to green jointing can be completed at one time, on the basis of applying plantar fertilizer, apply urea 30-50 kg per mu or 40 kg of high-nitrogen compound fertilizer, apply urea about 25 kg per mu of grouting, and water the grouting water. Potassium dihydrogen can also be sprayed twice every five to seven days.

Yes, from the perspective of wheat growth before wintering, it also needs a certain amount of water and fertilizer, and sufficient water is conducive to better tillering and seedling growth of wheat before wintering.

In order to promote good roots, fast greening, early tillering, the formation of enough strong tillers, to achieve high yield of growth, to scientific water and fertilizer management as the center. In order to meet the physiological water demand requirements of rice, water should be used to regulate the growth and development of rice plants, and the water management at the tillering stage should achieve "inch water returning to green", "thin water tillering" and "timely tillering control".

Hello dear, I am honored to receive your question to make you wait for a long time, hello dear, when wheat is sown, the bottom fertilizer is best to choose ternary compound fertilizer (such as nitrogen, phosphorus, potassium content is 15), you can also use diammonium and potassium fertilizer matching, of course, you can also use urea, phosphate fertilizer and potassium fertilizer respectively to apply the base fertilizer These fertilizers are very good wheat base fertilizer Thank you for your trust, the above is my reply, I hope to help you, I wish you a happy life Work smoothly, give a thumbs up if it is convenient, thank you.

Wheat fertilization in winter is good in spring, what is the best fertilization in wheat in winter.

Kiss. Hello, wheat fertilization in spring is better! Wheat fertilization time 1

Base fertilizer, wheat planting process of the rationality and adequacy of the bottom fertilizer is directly related to the growth and yield per mu, the amount of fertilizer accounts for more than 60% of the entire growth period, the bottom fertilizer is recommended to farm fertilizer-based, but to go through fermentation treatment, 2000kg per acre, at the same time with the application of vine microbial agents, can effectively improve the soil, plough high land, if there are conditions, you can take soil testing formula fertilization to improve the effect 2Late topdressing (1) nitrogen fertilizer, spring and winter wheat into the regreening period, at this time to supplement nitrogen fertilizer, for wheat tillering, jointing and other two periods to provide sufficient nutrients 2) booting fertilizer, wheat jointing booting stage nutrient demand is high, which is related to the yield and quality of wheat, under conventional circumstances, growers to irrigation water-soluble fertilizer to supplement nutrition, with the realization of land transfer planting scale, more use of foliar spraying to top dressing, foliar top dressing is not only high efficiency and nutrient replenishment fast, can choose vine leaves containing amino acids foliar fertilizer to spray.

Winter wheat is the main food crop, and it needs to go through seedling, tillering, regreening, jointing, booting, grain filling and maturity throughout its life. The winter wheat area in northern China needs low temperature and dry weather in winter and spring, and the growth period is long, which is one of the crops that need more fertilizer. The results showed that under general cultivation conditions, about 3 kg of nitrogen, kg of phosphorus pentoxide and 2-4 kg of potassium oxide should be absorbed from the soil for every 100 kg of wheat, and the ratio of nitrogen, phosphorus and potassium was about 3:

In addition, the fertilizer requirements of winter wheat were different at different growth stages, and the nutrients absorbed more at the tillering stage before winter, less nutrients at the overwintering stage, and more nutrients absorbed after regreening. The peak period of nutrient uptake in winter wheat is from jointing to flowering. The jointing phase is a period when reproductive growth and vegetative growth go hand in hand, and there is a great demand for nutrients.

Therefore, jointing fertilizer should be reapplied to increase the number of grains per panicle. For the vigorous high-yield fields, 20 30 kg of high-nitrogen compound fertilizer was applied per mu at the jointing stage.

It can reduce ineffective tillering, promote stalk robustness, improve wheat lodging resistance, and strive for large spikes, plump and multi-grain weight. Fertilization technology points: apply special fertilizer to cultivate strong seedlings. As the agricultural proverb goes, "the wheat in the belly is rich, and the bottom fertilizer is the base".

The application of base fertilizer can promote the early growth of strong seedlings and roots, and there are a certain number of healthy tillers before winter, which lays the foundation for panicle growth, grain increase and weight gain after spring. Generally, before sowing, basal fertilizer is applied in combination with ploughing and land preparation.

In dryland, fertilizer can be applied deep to the bottom of the plough and then ploughed and mulched*; * Heavy soil plots, first apply fertilizer, then plough and turn fertilizer into *. The spring growth of winter wheat is a critical period for tillering, ear formation and dry matter accumulation, as well as a period of high nutrient demand. On the basis of understanding the growth and fertilizer demand of spring and winter wheat, it is of great significance to formulate a reasonable fertilization plan to improve the yield and quality of wheat.

As far as tillering is concerned, although some fields have good growth in the early stage and have more tillers, tillering does not mean full panicles. We call what can't be an ear invalid, and what can be an ear is called valid.

Be sure to ensure that the base fertilizer is sufficient, before planting must be supplemented with more base fertilizer, and then according to different growth conditions to supplement fertilizer, such as phosphate fertilizer, nitrogen fertilizer, potassium fertilizer, organic fertilizer, when using nitrogen fertilizer, we must choose the appropriate ratio according to the planting area, try not to use it when the temperature is relatively low or when it is snowing, and we must mix a variety of fertilizers together.

When hanging the paint, we must supplement organic fertilizer and foliar fertilizer in time, which can improve the drought resistance. Rejuvenation and jointing are also very important. Try to choose medium and low concentration fertilizers, try not to choose high concentration fertilizers, you can sprinkle more at the beginning, but also pay attention to timely watering.

It is necessary to fertilize reasonably according to the growth of plants, and in the early stage, some urea or compound fertilizer will be used in general, so that the plants can grow better.

Apply a bag of compound fertilizer per mu) as base fertilizer, apply 30 kg of urea in the green stage, and apply 20 kg of urea in the jointing stage.

The stalk is erect, and the morphological characteristics of wheat are clustered, with 6-7 nodes, 60-100 cm high, and 5-7 mm in diameter. leaf sheaths flaccidly phimosis, the lower ones are longer than the upper ones and the internodes are shorter; leaflingual membranaceous, about 1 mm long; The leaves are long lanceolate. Spikes erect, 5-10 cm long (except Miscanthus), cm wide; Spikelets contain 3-9 florets, the upper part is not developed; Glometrius ovate, 6-8 mm long, the main vein is ridged in the upper part of the dorsal part, extending to a tooth about 1 mm long at the apex, the dorsal ridge and parietal teeth of the lateral vein are not obvious; ectope oblong-lanceolate, 8-10 mm long, apex with or without mang; The inner and outer bars are several equal lengths.

The soil layer is deep, the structure is good, and the tillage layer is deep, which is conducive to water storage and fertilizer conservation, and promotes root development. Soil structure refers to the composition ratio of solid (organic and inorganic), liquid and gas, which is closely related to soil moisture, air, temperature and nutrients.

The average daily temperature of winter varieties was 16 18, semi-winter was 14 16, and spring was 12 14. The temperature of the sky is affected by the geographical latitude and altitude, that is, the higher the latitude and altitude, the lower the temperature, and the earlier the sowing date.

Wheat long day crops (8 to 12 hours of light per day) if the sun conditions are insufficient. It will not pass through the light stage, and it will not be able to tassel and bear fruit. The light stage of wheat is after the vernalization stage.
