With the development of the aquaculture industry, there are more and more pig farmers, so how can the pig farms achieve the combination of breeding and breeding? How can pig manure be treated to avoid burning crops? Is there a way to quickly ferment pig manure into organic fertilizer? These problems must be also concerned by the majority of pig farmers. Hui Nongwang Xiaobian published some opinions on the above points for farmers to understand.
Let me talk about the combination of breeding and breeding. This is an ecological recycling agricultural production mode that the country has been vigorously advocated in recent years. Specific to the pig farm, the performance is: the pig farm ferments the pig manure and urine produced daily into organic fertilizer, and then applies the organic fertilizer to the crops. The crops using organic fertilizer are generally safer and healthier, and the harvest is also more. The harvested crops can be made into pig feed and fed back to the farm. They can also be sold to the market to obtain income. The straw left after the crop is harvested can be used to make pig feed, litter, etc. It can also be fermented into organic fertilizer with pig manure and re-entered into the field. All in all, the core concept of planting and breeding is to recycle resources, not to produce a trace of waste and pollutants, and to realize the ecological protection of modern agriculture.
The pig farm wants to achieve the combination of breeding and breeding. The first and most crucial step is to ferment organic fertilizer. People who have some experience in agricultural production know that livestock manure such as pig manure cannot be directly applied to the field for fertilizer use for the following three reasons:
First, the current pig manure contains a large number of bacteria and parasites and antibiotics and other drug residues. Direct application will lead to the spread of pests and diseases, crop disease, and affect the health of people who eat agricultural products.
2. Untreated pig manure contains a large amount of undigested organic matter. Once the temperature, oxygen and water are suitable, it will be fermented. The heat generated by the fermentation will affect the growth of the crop, causing root burning, burning seedlings and even plants. death.
Third, the unfermented and decomposed pig manure is mostly macromolecular organic matter, which cannot be directly absorbed and utilized by crops, and has low fertilizer efficiency.
In order to avoid the above harmful effects, pig manure must be fermented into organic fertilizer. However, fermented organic fertilizer is not so simple. The traditional fermentation method is composting, which uses the natural fermentation of manure. However, this method takes a long time and often takes three to six months. During the fermentation process, the smell is large and air pollution is easy to occur. This method is forbidden in places.
The most common and economical fermentation method nowadays is the use of specialized fertilizer starters. In general, 1 kg of fertilizer starter can fertilize 1.5 tons of pig manure (about 3 tons of fresh manure). The fermenting agent should be mixed and diluted with rice bran (or corn flour, wheat bran, etc.) in a ratio of 1:5, and evenly sprinkled into the pig manure material pile, mix evenly, and adjust the moisture content of the fermentation material between 60 and 65%: Hold a hand tightly on the material, and see the watermark on the fingertips, but do not drip the water. Then, the pig manure mixed with the fertilizer starter should be piled up, not too small (1.2~1.5 meters high, 2~2.5 meters wide, 2~4 meters long), and should be overturned 2~3 times during the fermentation process. The control temperature is about 65 degrees, and the fermentation can be completed within one week.
Although the starter is very convenient, the fermentation agents sold on the market are varied and have different effects. When you choose, it is best to choose a well-known product that has withstood the test of the market, beware of being deceived.
The combination of breeding and breeding of pig farms can not only be environmentally friendly, but also bring good economic benefits. It can be said that they have two birds with one stone. Therefore, the farmers have to take a quick look. The above is the rationalization of pig farms combined with pig manure and urine. Use method!
There are many kinds of raw materials and different properties of cosmetics. According to the properties and uses of raw materials, cosmetics can be generally divided into two categories: substrate raw materials and auxiliary raw materials.
The former is a kind of main raw material of cosmetics, which occupies a large proportion in the formula of cosmetics, and is the substance that plays the main function in cosmetics. The latter are responsible for forming, stabilizing or giving color, fragrance and other properties of cosmetics, which are used in small amounts in cosmetic formulations but are extremely important. Cosmetics are chemical mixtures made from natural, synthetic or extracted substances with different functions, which are processed by heating, stirring and emulsifying.
