Fertilizer is a very important one for crops. Because fertilizer is the source of crop nutrition, we must not only understand their effects when fertilizing, but also understand the choice of fertilizer and how to use it. Some farmers' friends may not be aware of some of the use of fertilizers, so today Xiaobian talks about some of the knowledge about how to use all kinds of farmyard manure properly.

1. Poultry manure: Poultry manure has high nutrient content and can be used as seed fertilizer and top dressing. It is most suitable for vegetables.
2. Human excrement: Human excrement can be used directly after fermenting and fermenting, or it can be mixed into the soil to make large manure for top dressing.
3. Composting: Composting is a fertilizer that is made up of weeds and garbage as raw materials. It is best to combine spring and autumn tillage to make base fertilizer.
4. Green manure: Green manure generally uses the base fertilizer or top dressing of legume crops, and uses the nitrogen fixation effect of rhizobia to improve soil fertility.

5. Sheep manure: Sheep manure can be mixed with pig manure. Sheep dung can be used in cool soil and on sloping land.
6. Pig manure: The organic matter of pig manure and the content of nitrogen, phosphorus and potassium are used for various soils, especially the hot soil with good drainage performance.
7. Horse manure: Horse manure has high content of organic matter, nitrogen and cellulose, and contains high-temperature fiber-decomposing bacteria. The fermentation speed is high and the heat generated is high in the accumulation. Therefore, horse manure is often used in agricultural production. On the sticky land, there is a sloping land.
8. Cow dung: The nutrient content of the cow's manure is not very high, but the cow dung can be dried in the sun, and a small amount of grass ash or horse manure can be added for fermentation, which can improve the fertilizer effect of cow dung, so when the cow dung is used Can be combined with hot fertilizer, or applied to sandy soil and sunny slopes.
These are some of the ways in which various types of farmyard manure should be used correctly. You can take a serious and careful look, because this can be used when we grow crops ourselves, and we know more about some fertilizer knowledge, to a certain extent. It can also be applied to agricultural production.

Real Time fluorescence quantitative PCR system is a variation of the standard PCR technique that is commonly used to
quantify DNA or RNA in a sample.
Using sequence-specific primers, the number of copies of a particular DNA or RNA sequence can be determined.
By measuring the amount of amplified product at each stage during the PCR cycle, quantification is possible.
