"Pig does not make money, look back at the field," this rural proverb has what enlightenment?

Thank you for the invitation! Like it, please remember to like and follow!

In rural areas, the traditional sense of family-style pig farms, pig farming, pig manure circulation, there is no pollution problem! In the past, China was dominated by a small-scale peasant economy, and land was the basis for settling down. And raising pigs can only be regarded as "alternative"! Raising pigs is not for pigs, but for raising fields with pig manure! This is also the malpractice of our traditional agricultural development for thousands of years! In the new era, pig farming is no longer limited to the interests of the pig itself, for the benefits of manure composting has been recognized!

Raising pigs doesn't make money. Look back at the fields.

In recent years, with the rapid development of China's economy, the material and cultural life of the people has gradually improved! The requirements of the quality of life are also constantly improving! The supply of meat products is also increasing! In comparison, the scale of pig farming is also constantly expanding, especially in recent years, pig prices continue to rise, and the phenomenon of raising pigs in rural areas is serious! However, pig farmers in some areas have little awareness of environmental protection, and there are many pollution problems in pig farms. Since 2016, a "storm" against breeding pollution control has swept through the pig industry! The vast number of retail pig farmers in rural areas are going and staying complicated and confusing! The only thing that is certain is that the pig farm waste must be disposed of!

In fact, isn't this the same truth contained in the rural proverb "raising pigs doesn't make money, look back at the fields?" The only difference is the scale of raising pigs! The traditional pig industry takes the family as the unit, the breeding scale is small, the pig manure is easy to deal with, and the farmland at home can be absorbed directly! Today, most pig farmers no longer farm, and farmers do not raise pigs! On one side, resources are stacked to pollute the environment, while the other side is looking forward to the lack of fertilizer on the land! What is missing from this phenomenon is the resource treatment and utilization of pig manure!

At present, the mainstream manure resource treatment modes in pig farms are roughly divided into two types:

First, the cycle of planting and breeding, returning ecology to the field!

This kind of pig manure resource treatment model and the traditional pig farming, pig manure returned to the field is roughly the same, but the difference is the scale! Large-scale pig farms must have matching land pollution bearing capacity! After "two-thirds conversion and reuse" in pig farms, pig manure microorganisms are anaerobic fermented and biogas is used for daily life or biological power generation! And biogas residue and biogas slurry are used in agricultural cultivation to give full play to the economic and social and ecological benefits of raising pigs!

Second, "turn waste into treasure" aerobic composting

Pig manure is a high quality raw material for the production of organic fertilizer! Pig manure composting is not only a zero discharge project of pig farm manure, but also another channel to broaden the income of pig farm. Not only in large-scale pig farms, but also in rural retail pig farmers have been widely promoted! This article will not be described in detail, there are unclear pig friends can pay attention to me, there are some techniques of ectopic fermentation bed composting made a few days ago!

In short, most of the proverbs in rural areas are rough and reasonable. For our contemporary pig farmers, whether in rural areas or large-scale pig enterprises, "raising pigs does not make money, looking back at the fields" still has practical significance! If pig manure is handled well, it is impossible not to make money! In fact, this is also the key to the sustainable development of pig-raising economy in the "integration of planting and breeding, the cycle of agriculture and animal husbandry".
