What fertilizer to use for farming with corn no till machine for high yield

1. Corn-based fertilizer is mainly organic fertilizer, phosphorus and potassium fertilizer, and micro fertilizer.

2. Organic fertilizer is mainly used on plants and (or) animals, and is applied to the soil to provide plant nutrition as its main function of carbon-containing materials. It is processed from biological substances, animal and plant wastes, and plant residues, eliminating toxic and harmful substances, and is rich in a large number of beneficial substances, including: a variety of organic acids, peptides, and rich nutrients including nitrogen, phosphorus, and potassium.

It can not only provide comprehensive nutrition for crops, but also has long fertilizer effect, can increase and renew soil organic matter, promote microbial reproduction, improve the physical and chemical properties and biological activity of soil, and is the main nutrient for green food production.

3. Crush the (phosphorus) potassium ore to a fineness of about 100 mesh, and the sieve residue is less than 15%, and then be enriched and sterilized at high temperature; With peat, agar, glucose, sulfate, ammonium salt, molybdenum salt, fungus and other auxiliary materials, the proportion of mineral powder auxiliary materials = 85 95 2 2 5;After batching, the biochemical reaction is carried out in the reactor. After the reaction is completed, granulation is made according to the ratio, and after granulation, biological (phosphorus) potassium fertilizer containing more than 20% P2O5-K2O can be made.

3. Micro fertilizer is the abbreviation of trace element fertilizer.

Generally speaking, the top dressing of corn is mainly urea and compound fertilizer, but can not be casually top dressing, to be determined according to the soil situation, growth stage and soil characteristics, such as acidic soil can generally be used urea to top dressing, and for the sandy soil with poor water and fertilizer retention ability, you can use non-volatile ammonium nitrate for top dressing, the seedling stage can not be prematurely top dressing, after the corn enters the male and female flower formation stage, generally can not be too late.

Generally speaking, compound fertilizers should be chosen. This can be a good supplement of trace elements, and can also promote the growth of plants, which can improve the disease resistance of plants.

It is better to choose compound fertilizers. Such a fertilizer will have more nutrients, and it can also ensure the yield, which can make the growth very good.

Corn and Natucha are not suitable for no-top dressing for the following reasons:

Problems with the manuscript when applying without top dressing:

1. If the fertilization depth is not enough, the phenomenon of burning seedlings will occur in corn;

2. The uneven application of mixed topdressing-free fertilizer leads to excess or insufficient nutrients of corn;

3. The use of fertilizer does not distinguish between soil quality, resulting in seedling burning, loss of fertilizer, premature senescence and defertilization, etc., which affects the yield and income of crops.

No top dressing needs to be applied deeply, and no top dressing can not provide nutrition when corn seedlings are just out, which makes the early nutrition of corn insufficient, and the growth is affected, which in turn affects the yield. According to the test, the use of no-top dressing will reduce the yield by 15%.

Corn no-tillage planting is a planting method that directly sows corn on the basis of the previous crop of the current year without land preparation. In our northeastern region, no-till seeders are now also used to sow corn directly on top of last year's crop. The ability of soil to absorb fertilizer and water is closely related to the content of organic matter in the soil and the porosity between soil particles.

Under the premise that there is no big difference in organic matter content, the fertilizer and water retention capacity of the farmland after deep ploughing will be better than that of the no-tillage plot.

Corn no-tillage sowing technology operation process: 1065 combine harvester harvests wheat Weeping claw wheat straw crusher crushes wheat straw and spreads straw at the same time (baler bales the plot with more straw to prevent the straw from clogging the no-tillage seeder) No-tillage seeder sowing corn no-tillage corn field is based on loose soil, no trees and other plant roots compete with corn for fertilizer land, it is possible to sow corn without tillage, and the yield is as high as that of plowing corn field. In the case of muddy or acidic compacted soil, and land with a large number of tree roots.

No-tillage corn is not high yield, because the seedling root system and seedling emergence rate have an impact, in our local is subsoiling plus rotary tillage combined with special fertilizer and high-yield corn varieties and later management, can achieve a good yield of this no-tillage sowing corn, because the cultivation is relatively shallow, the depth can not reach the nutrients required by corn seedlings, in addition, even if you fertilize, the fertilizer will also be affected because it is too close to the root system, and the watering will not be as deep as the ordinary cultivated ground.

The first is to rush to broadcast early. Because summer maize is suitable for growing for a short time, once sown late, it is likely to encounter low temperatures at the maturity stage, resulting in reduced yield. Therefore, it should be sown as soon as possible after harvesting wheat.

Today's farmers all know that the corn grown in wheat fields is no-till. And all of them have achieved the purpose of high yield and stable production. Spring no-tillage will also become the development trend of new agricultural planting.

Subsoiling can effectively break the hard bottom layer of the plough, increase soil permeability, promote the root system of crops, improve the ability of soil water storage and moisture conservation, drought and flood resistance and lodging resistance, and is conducive to the up and down conduction of water, fertilizer, gas and heat in the soil, and improve the crop growth environment.

It is really cost-effective and high-yielding, it has disadvantages, the soil is compacted for large mechanical operations, which will lead to slow emergence in the early stage, and the ability of the soil to absorb water and nutrients after compaction will also decrease.

Corn no-tillage sowing technology has also been promoted in recent years, the advantage of no-tillage technology is to save labor costs, as some feed corn types are used more. Although no-tillage technology saves costs, it still has a certain impact on the growth of corn seedlings.

Really, but there are also disadvantages, the soil is heavy and hard, and there are many roots left in the soil from the previous crops, so it is not conducive to the increase of corn roots and deep rooting (underdeveloped roots).

Hello, I have helped you find the result; The disadvantages of no-tillage precision application side fertilizer seeder are as follows: 1: High installation and maintenance cost of concealment flushing: The installation and maintenance of no-tillage machines usually require professional technology and equipment, and the stove will increase a certain cost.

2: High initial investment cost: Compared with traditional seeding machinery, no-tillage precision fertilization seeder has a higher level of production and requires a higher initial investment.

3: High requirements for soil quality: The machine is suitable for relatively good soil conditions, non-acidic soil, so if the soil quality of the farmland is poor, the adaptability to the machine will be reduced.

There are many advantages of no-tillage, precision fertilization and seeding tools, which can improve agricultural production efficiency while protecting the soil environment and reducing energy consumption.

Urea is nitrogen fertilizer, nitrogen is very active, quick effect, fertility concentration, but the fertilizer effect is short, so it is suitable to do top dressing, throw fertilizer to the ground to cover up in time to avoid nitrogen molecules with the air and reduce fertilizer efficiency.

Most of the corn we grow here is mixed with fertilizer, and four plants are piled up at a time. The sky was overcast and very hot, my wife and I worked tightly, and when there was a third of the two acres of land left, the rain was pouring down, and my wife and I only took the box and sprinkled it into the ground. After half a month, I went to the first trembling ground to take a look.

A few days ago, I also talked about the problem of crop topdressing, which also talked about urea, of course, some netizens said that potassium dihydrogen phosphate can be used, which is okay, and some say that compound fertilizer can be used, which is also correct, mainly to see what the crops lack, we will chase. Generally speaking, in the crops in Dalian, the top dressing is also directly put on the ridge of the corn with urea, close to the corn roots, the average person divides the top dressing many times, each time a handful of urea can chase 3 to 4 corn. If the moisture is good, the soil is relatively soft and moist, and the utilization rate of chemical fertilizer has a good absorption effect, on the contrary, if encountered.

<> first time, when the seedlings have grown to a height of 30 to 50 centimeters, urea is cut into the ground at a depth of 10 centimeters, about 20 centimeters away from the plant. The fertilization speed with this kind of furniture is fast, the amount of fertilizer is uniform, and the effect is good. There is also a disadvantage of fertilizing with a rake, the plant grows to a meter high to dissolve quickly, even if it is sprinkled for a few days to see, if there is no urea dripping from the corn leaf dew, it is still not dissolved after a few days, and by the high temperature evaporation of the sun, urea nitrogen will definitely volatilize a part, so it is not only a waste of fertilizer and a waste of money, and corn is notFirst of all, it is analyzed according to the nature of urea.

The nitrogen content is 46%, the chemical properties are extremely unstable, and it is easy to decompose and volatilize. If you fertilize corn, you will throw urea directly into the ground, and the nitrogen fertilizer will volatilize after dissolving in moisture, resulting in the loss of fertilizer, which will not have the effect of fertilization and cause economic losses.

In the spring, when sowing, apply some farm fertilizer, then when the corn grows to 20 cm, apply some organic fertilizer, and when it is 40 cm, apply some fertilizer. Disorderly.

According to the yield level of maize, consider the soil fertilizer supply capacity to determine the reasonable total amount of fertilizer. The amount of fertilizer required by corn is different at the end of the year, so it is necessary to do a good job of topdressing at the ear stage, and reapply fertilization at the big bell stage. To reduce losses, fertilizers should be applied deeply.

Phosphate fertilizer has poor mobility, and phosphate fertilizer should be applied intensively. Choose a suitable elemental fertilizer or a compound (mixed) fertilizer with a reasonable ratio, and inject the sparrow liquid to supplement zinc and other trace element fertilizers.

Sufficient fertilizer, not too much fertilizer each time, otherwise it is easy to cause the corn to be burned to death.

Corn fertilization principle: basal fertilizer should be based on organic fertilizer, supplemented by chemical fertilizer, basal fertilizer is a fertilizer for slow rolling before sowing, also known as base fertilizer, its important role is to fertilize the soil, loosen the soil, slowly release nutrients, and supply the needs of corn seedling and later growth and developmentNongqing's household fertilizer (3000 kg to 5000 kg per mu of high-quality farmhouse organic fertilizer), supplemented by chemical fertilizer, and nutrition to meet the fertilizer needs of corn growth and development.

Generally, corn formula fertilizer formulas are diverse, which can meet the growth needs of corn in various places and the fertilization habits of local farmers. Compound fertilizer: nitrogen, phosphorus, potassium compound fertilizer or diammonium phosphate is the best seed fertilizer, 10 kg to 15 kg per mu.
