What fertilizer is good for Dajing? What is Big Fertilizer?

The Great Shinobi is very adaptable, the choice of soil and climate is not strict, and the fertilization is mainly urea.

Red Triangle, Luxi, Yangfeng, etc. are all available. The quality of Sinochem is relatively stable, but it belongs to the mid-to-high-end price. If you are growing high value-added crops such as vegetables and fruit trees, then you can consider using high-end products such as Patian, Sakefu, etc.

If you are growing field crops such as wheat, corn, peanuts, and rice, you should use ordinary second- and third-tier fertilizer brands. 15-15-15s ** around 170-185 a bag.

I can't tell which one is the best quality, and it's not high.

It can only be said that the quality of those well-known brands is relatively good.

Cheap is not good, good is not cheap.

Good stuff is only going to get more expensive.

Liaoning Kaifeng fertilizer incident.

Organic fertilizer (but not chemical fertilizer), chemical fertilizer is compound fertilizer, the nutrients required by plants are available, and the disadvantage is that it is easy to make the soil compact, so it is best to use organic fertilizer.

The concept of man-made refers to the kind of fertilizer that is generally 40-50 kg packaged in large quantities in large quantities, which is the main means of production in agriculture, large-scale circulation operations, and relatively low single profit margins.

Corresponding to the so-called high-tech fertilizer of small packets of water-soluble fertilizer, liquid fertilizer, etc., the unit ** is higher, and the profit is also larger.

Chemical fertilizers are referred to as chemical fertilizers. Fertilizers made by chemical and (or) physical methods containing nutrients necessary for the growth of one or several crops. Also known as inorganic fertilizer, including nitrogen fertilizer, phosphate fertilizer, potassium fertilizer, micro fertilizer, compound fertilizer, etc.

They have the following common characteristics: simple composition and high nutrient content; The fertilizer effect is fast, and the fertilizer is strong; Some fertilizers have acid-base reactions; Generally, it does not contain organic matter, and there is no effect of soil modification and fertilization. There are many types of chemical fertilizers, and their properties and application methods are quite different.

Fertilizers are divided into organic fertilizers and chemical fertilizers.

The main content of organic fertilizer is organic matter, which improves soil fertility.

There are many types of chemical fertilizers, including single mineral element fertilizer or nitrogen fertilizer, as well as compound fertilizer.

It depends on what is lacking in the soil and the growth stage of the crop that has been planted.

1. During the rapid expansion of the fruit, nitrogen, phosphorus and potassium fertilizers should be applied together, especially phosphorus and potassium fertilizers. Too much nitrogen fertilizer is harmful, it can induce disease and reduce the coloring rate of the fruit. Only through reasonable fertilization, coordination of the proportion of various required elements, improvement of light and efficiency and metabolic function of fruit trees, can the need for fruit expansion be ensured.

2. In the peak peak of fruit expansion, it is the best policy to take fast-acting fertilizer for rapid supplementation. First, water-soluble fertilizer: you can choose high-potassium water-soluble fertilizer, water-soluble fertilizer is a fast-acting soluble fertilizer, which is indispensable in modern agricultural production, with good solubility and high absorption and utilization rate.

The second is foliar top dressing: foliar collapse spraying is carried out for some melon and fruit crops in the mature period, and potassium dihydrogen phosphate can be sprayed to play a number of roles such as expansion, coloring, and increasing taste sweetness.

The types and main functions of fertilizers are analyzed as follows: the types of fertilizers mainly include nitrogen fertilizers, phosphate fertilizers and potassium fertilizers, and their different types have different functions.

Nitrogen fertilizer is a component of chlorophyll, which accelerates the growth of plant roots, stems and leaves. Phosphate fertilizer can help seed germination, not only to help root growth, but also to promote tillering, branching, and flower and fruit. Potassium fertilizer is very helpful for the growth of bulbs, which can improve the cold and disease resistance of plants, and can also make the stems and branches grow stronger.

Because the plant initially absorbs nitrogen fertilizer, even if the same ratio of N p k fertilizer is applied, the plant will still prioritize the nitrogen fertilizer until it is excessive. Therefore, fertilizers with a low proportion of nitrogen fertilizer should be applied as much as possible.

In addition to the above three elements, trace elements such as iron, manganese, copper, and zinc are also important nutrients, which can regulate the physiological functions of plants. When cultivating plants, it is called "base fertilizer" mixed into the soil in advance; After potting, it is called "top dressing". Fertilizers can be divided into organic fertilizers and inorganic fertilizers.

Common organic fertilizers: there are fermented products such as poop, animal and plant residues, soybean cakes, oil residues, horseshoe, rice water, and leftover yogurt. Common inorganic fertilizers: urea, potassium dihydrogen phosphate, ferrous sulfate, ammonium bicarbonate, etc.

Most of the compound fertilizers belong to inorganic fertilizers, but there are also a small number of products that belong to long-lasting organic fertilizers.

Organic fertilizer and inorganic fertilizer have different ways to use, and only according to different fertilizers can be applied in a corresponding way to achieve better results. Otherwise, not only will it not have a good effect, but it will even cause fertilizer damage or fertilizer waste.

Garlic potassium sulfate compound fertilizer is good.

Planting garlic with nitrogen, phosphorus and potassium (15 15 15) potassium sulfate compound fertilizer has fast and many roots, developed roots, strong absorption capacity, good growth of garlic seedlings, strong stems and green leaves. Nitrogen, phosphorus and potassium fertilizers are also needed in the growth of nitrogen, phosphorus and potassium fertilizers, which need to be applied reasonably, and the demand for these three elements is different in different periods, so it is necessary to pay attention to the ratio of sulfur fertilizers.

In the general preparation of fertilizers, potassium sulfate, superphosphate, urea, monoammonium phosphate can be used as the main fertilizers, with the addition of some trace elements, you can meet the demand.

How garlic is grown

1. Choose good breeds

The selection requirements of garlic seeds are pure white without red tendons, no scars, no saccharification, no smooth skin, it should be noted that the size of the seeds is one of the key factors for high yield of garlic, generally speaking, the size and weight of garlic seeds is about 5kg.

2. Sow seeds at the right time

Garlic is a kind of cold and cool crop, with the characteristics of natural dormancy, sowing too early will be because it is still in the dormant period and the emergence of seedlings is slow, after the emergence of the seedlings will be due to the high temperature in the early stage, the growth before winter is too vigorous and the cold resistance of garlic seedlings is greatly weakened. If the sowing is too complete, it will lead to too little nutrient accumulation in the seedlings, which will shorten the growth period of garlic stems and leaves, and reduce the number of leaves, thus affecting the quality of garlic. Therefore, it is especially important to choose the right sowing thing.

3. Sowing density

When sowing, we should try to choose larger garlic cloves for seeding, which can fully ensure the nutrient absorption of garlic and is conducive to the growth and development of garlic. Generally speaking, you can choose 5g heavy garlic cloves for seeding, and the planting density is kept at about 10,000 plants per mu.

4. Prepare the land and sow seeds

In order for garlic to be of high quality and high yield, it is necessary to apply sufficient fertilizer when planting. In addition, every 3 furrows can also pick a high furrow with a height of 15 cm, which is convenient for watering and retaining water. After the garlic clove sowing is completed, it is also necessary to cover the soil in time, fill the ditch, and then water the root to prevent the garlic clove from being pushed out of the ground when the seedlings take root.
