Thermostat raising technology
In the past, people mistakenly believed that the constant-temperature breeding and the constant-temperature culture of earthworms seemed to be the same thing. In fact, from the normal-temperature farming to the constant-temperature farming, it needs an evolutionary process. Through dissection, it was found that the same-age scorpion scorpion was filled before the transformation, the constant-temperature cultured quail was more than the normal-temperature breeding scorpion, and the surrounding cells were well-developed. This is an important reason for the rapid growth of the constant-temperature breeding quail. Multi-generation constant temperature breeding evolved. After distinguishing and grasping the characteristics of their own rearing, it is necessary to select their varieties according to their respective feeding forms. This is very important for improving the yield of artificially cultivated rice dumplings.
The so-called constant-temperature breeding refers to the method of artificial warming, so that the temperature of the breeding space is always kept within the range suitable for the normal growth and reproduction of the medlar, and is not affected by changes in the external environment and the season. Therefore, it is also called “winter raisingâ€. "Rapid breeding" and "no dormancy breeding."
Incubation, due to changes in the environmental conditions (mainly low temperature) of the adverse impact on the mother's growth and reproduction, that is to break the dormancy caused by the low temperature in the natural state, which can make the dumplings all year round Can normal growth and development and reproduction. At the same time, because it is in the relatively "constant temperature" (rather than the high temperature and low temperature), it can make the growth rate of the gardenia faster. The life cycle is shortened, that is, it takes 3 to 4 years at room temperature to develop into a loquat, and it can be shortened to only 8 months to develop into a loquat. The mature female loquat is also only produced annually under natural temperature conditions. After 1 time, it is increased to achieve stable yields twice a year. Therefore, raising temperature at a constant temperature is expected to obtain higher economic benefits than breeding at room temperature, and has a broader development prospect.
Compared with raising temperature at room temperature, there is no significant difference in breeding methods between the temperature-raising and the raising of earthworms, ie, there are mainly pond raising, raising, pot raising, and box raising; on the farming scale, they can also be divided into large, medium, and small, etc. These can be adapted to local conditions. However, in terms of breeding equipment, it is necessary to have warming measures in the cold season, which is the most important technical key for constant temperature culture.
The constant-temperature breeding quail is a fast-growing pod that has undergone several generations of regeneration, screening, and hybridization. The body has well-developed cell structures, accelerated physiology, and long-term high-circulation. In the breeding process, the dependence on the growth of the season is completely changed, and it is artificially cultivated according to the necessary conditions for the growth of the crickets of each age. Depends on the temperature, the response to sound, vibration and light is more stable. In terms of appearance, the temperature of the cultured alfalfa appendages was yellow and transparent, and the body was black and shiny with a wide, fat abdomen, which was 2 to 4 mm wider than the wild, and the temperament was mild. The average weight of each wild cricket is about 1.39 grams, while that of the constant-temperature breeding crickets is more than 0.17 grams per gram.
1 . The development and significance of raising the temperature at the constant temperature The current family breeding lice are mostly domesticated from wild scorpions, so the living habits of the two are basically the same. Scorpion as a kind of temperature-changing animal, it will go through 4 stages of life in a year in the wild: that is, from the convulsions to the Ching Ming for the recovery period; with the Ching Ming to Bai Lu for the growth period; from the white dew to the frost for the nutrient storage period; from the beginning of winter to Convulsions are hibernation. In these four stages, temperature and humidity are the main conditions that determine the survival of lice.
The nephew who lives in the wild takes about 3 years from Aberdeen to Chengju, and it takes a very long time. If we can artificially change the sleeping habits of Scorpion and let the Scorpion not hibernate, it means that the Scorpion's growth cycle will be shortened and the economic benefits will be greatly improved.
Since temperature is the primary factor influencing the growth and development of scorpion, we artificially control the temperature of mortuary house and make full use of various ecological factors to create a constant temperature environment suitable for the growth and development of scorpion so that the scorpions will not hibernate all year round. In the best state of a body activity, this is the temperature raising method.
The temperature-raising breeding system has made great progress compared with the conventional room temperature raising system. First of all, it solves the problem of the “winter floods†that are prone to occur at room temperature, prevents the death of the scorpions when they are released, greatly improves the survival rate of scorpions, and secondly, the temperature of scorpions is greatly shortened. The growth cycle, it is about 30 months shorter than normal temperature. The third increased the number of births, increased the number of births from 1 at room temperature to 2 to 3 times now, and the birth rate has also been greatly improved. In other words, the output of dumplings per area of ​​the practical unit is increased by 7 to 8 times per year compared with the normal temperature. The breeding practice in recent years has proved that the economic benefits of implementing scientific breeding, scientific management, and temperature-raising breeding methods are considerable. For this reason, the constant-temperature breeding technology has become a new hot spot for farmers to raise their alfalfa.
2 . The form and facilities of temperature-raising cultures (1) The form of raising turtles is only two types of constant-temperature farming: one is the constant-temperature breeding, and the other is the plastic cultivation of greenhouses. These two forms can be selected. However, no matter which method is selected, the following five conditions must be met: 1 Economical and practical; 2 Conditions for heating and heat preservation; 3 Good ventilation performance; 4 Reasonable building structure for easy observation and feeding;
(2) Housing facilities Room housing is a common form of farming. Because of the effects of human, the temperature and humidity are well controlled, and the sound insulation effect is good. The light is strong, and the amount of culture is large, but it only increases the heating energy. Under the economical conditions, a special breeding greenhouse can be built: the top of the house is built on the principle of solar heating, which can use sunlight and heat and make full use of space, so that the advantages of the two can be combined. From all angles, this can create a good condition for the scorpion to grow and reproduce.
