How to keep warm greenhouse greenhouses in winter

How to insulate and heat up greenhouse insulation in winter greenhouses has always been a key issue for growers, especially in northern China, and even affected the healthy development of the vegetable industry. In response to this problem, agricultural experts and the majority of growers have thought of many methods, such as multi-layer insulation, heating by lamps, heating by heating lines, and heating by hot air ovens. Although it has achieved certain results, it has also exposed many of its shortcomings and deficiencies, such as the need to increase equipment, increased costs, and some hidden dangers. There are no more economical, convenient, and ecologically friendly alternatives.
In fact, there are new methods that are more economical, ecological, and simpler. They are called "natural heating methods" or simply called "land air-conditioning methods", that is, the use of microbial fermentation to warm up and heat. The so-called "natural heating method" or "land air-conditioning method" is not that the temperature in the shed or the ground temperature will really increase for no apparent reason, but because of the innumerable behind-the-scenes heroes' hard work, this behind-the-scenes hero is a functional microbiological activity. Bacteria, such as actinomycetes, yeasts, filamentous fungi and other functional microorganisms in the fermentation auxiliaries. The specific method is: in the preparation of soil preparation, sorghum or seedbed, fill the soil with Fresh Chicken manure, pig manure, cow dung, fresh garbage, manure and cut short or crushed straw, straw, and then add the appropriate amount of starter, and finally The garden soil is buried so that the functional microbial species in the fermentation aid can be fermented using the above raw materials as nutrients. These raw materials are fermented and decomposed by actinomycetes, yeasts, filamentous fungi and other functional microorganisms in the fermentation aids. With a series of complicated biochemical reaction processes, they can slowly release heat and gradually increase the temperature of the soil and air to ensure the plants. The normal growth; also produced a large number of enzymes, humic acid and metabolites of functional microorganisms, these substances can loosen the soil, inhibit harmful bacteria, stimulate the development of the root system, and some can also convert the ineffective nitrogen in the air into absorbable The effective nitrogen will activate the invalid phosphorus and potassium elements in the ground as active phosphorus and potassium nutrients for crop absorption, thereby promoting the healthy development and growth of crops. This working principle is the same as the principle of using fermentation auxiliaries to produce a pig-spinning fermentation bed for heat preservation, deodorization and fertilizer production.

The nutritional value of chicken
1. Chicken protein content is high, and easily absorbed into the body to use, there is to enhance physical strength, strong body function. In addition, chicken also contains fat, calcium, phosphorus, iron, magnesium, potassium, sodium, vitamin A, B1, B2, C, E and niacin and other ingredients.
2. Chicken potassium sulfate amino acid content is also very rich, it can make up for lack of cattle and pork.

3. Chicken has more vitamin A than other meat, but its content is worse than that of vegetables or liver, but the content of vitamin A is much higher than that of beef and pork.


The efficacy and role of chicken
1. Chicken sex, warm, sweet, spleen, stomach; can be warm, supplement essence and marrow; for the treatment of Consumption thin, the less virtual diet, diarrhea, dizziness, palpitations, irregular menstruation, postpartum milk less , Diabetes, edema, frequent urination, tinnitus and other deafness.
2. Chicken on malnutrition, cold chills, fatigue, irregular menstruation, anemia, weakness and so have a good therapeutic effect. Chinese medicine believes that the chicken has warm, tonic fill fine, spleen and stomach, live blood, strong bones effect.
3. eat chicken cooking flowers can enhance the liver's detoxification function, improve immunity, prevent colds and scurvy.
