秋冬季节如何使用PVC通风管

How to use PVC venting in autumn and winter

进入秋季，怎么协调好鸡舍温度和通风成了广大养殖朋友最头痛的一件事。新盖的保温鸡舍利用PVC通风管通风的越来越多， 特别是在沧州地区很常见。针对PVC通风管类型的肉鸡鸡舍的通风，合理科学的应用通风管很重要!可以有效的缓解冬季通风量小而引起的空气质量差的问题。

Entering the autumn, how to coordinate the temperature and ventilation of the henhouse has become the most troublesome thing for the vast number of breeding friends. The newly built thermal insulation poultry houses are increasingly ventilated by PVC ventilation pipes, especially in the Cangzhou area. According to the ventilation of chicken chicken house with PVC ventilation pipe type, the rational and scientific application of ventilation pipe is very important. It can effectively alleviate the problem of poor air quality caused by small ventilation in winter.

冬季与初春通风目的：1、提供肉鸡需要的氧气（全程）2、降低湿度(育雏七天后)与减少灰尘（全程）3、减少和稀释氨气和CO2的浓度（全程）4、排出多余的热量、降低温度（20天以后）。

The purpose of winter and early spring ventilation: 1, providing oxygen for broilers (Quan Cheng) 2, reducing humidity (seven days of brooding) and reducing dust (Quan Cheng) 3, reducing and diluting ammonia and CO2 concentration (Quan Cheng) 4, discharging excess heat, and reducing temperature (20 days later).

15天以前以保温为主（4天左右开启长通风管并逐渐增加长通风管的数量）；15天-30天逐渐增加其他长、短通风管的数量，并逐渐增加排风机数量与通风时间；30天以后以通风为主，当通风与保温相矛盾时，以通风为主，温度取下限保温（以肉鸡均匀分布、无扎堆为肉鸡满足温度）。

15 days ago with thermal insulation (4 days or so to open long ventilation pipe and gradually increase the number of wind pipe); 15 days -30 days gradually increase the number of other long and short ventilation pipes, and gradually increase the number of ventilator and ventilation time; 30 days after the ventilation mainly, when ventilation and thermal insulation, ventilation mainly, temperature is taken down Xian Baowen (evenly distributed by broiler, no broiler to meet the temperature for the broiler).

1-15天的育雏温度下降波动范围小，用通风管换气的关键是不能有冷空气直接吹到鸡体。在冬天、初春肉鸡通风要掌握好通风管的风速与负压。

The temperature of the 1-15 day brooding is small and the fluctuation range is small. The key to ventilate the ventilator is that no cold air can be blown directly into the chicken body. In winter and early spring, ventilation and ventilation should be well controlled.

注意：鸡舍内哪处温度低，就减少该处通风管的进风量或减少该处通风管数量，哪一处温度高就增加该处进风量或增加通风管数量。

Note: where the temperature is low in the chicken house, it will reduce the air intake of the ventilation pipe or reduce the number of the ventilation pipe in the place, which will increase the volume of air intake or increase the number of ventilation pipe.

鸡舍密闭性检查： 鸡舍密闭越好，通风效果越好。

Closed inspection of henhouse: the better the airtight cabin is, the better the ventilation effect is.

鸡舍负压管理： 13米宽的鸡舍，育雏期负压值为20-25Pa。30天-出栏负压值为10-15Pa。整个饲养周期合理的负压应以人进入鸡舍不憋闷，不压气为正常标准（尤其对饲养后期非常重要）。

Chicken house negative pressure management: chicken house with a width of 13 meters, negative pressure value is 20-25Pa during brood. 30 days - the negative pressure of the column is 10-15Pa. The reasonable negative pressure in the whole feeding cycle should be that people should enter the henhouse without being stuffy and not pressurized as the normal standard (especially for the later stage of feeding).

PVC通风管的管理：通风管要与风机大小，数量相匹配，避免负压过大，造成鸡舍内肉鸡缺氧（鸡舍温度不偏高，正常的情况下，依然有部分肉鸡张嘴，不是温度偏高造成，而是鸡舍内负压大，压气，肉鸡缺氧而出现张嘴）。

PVC ventilation pipe management: the ventilation pipe should be matched with the size and quantity of the fan, avoid the excessive negative pressure, cause the chicken anoxia in the chicken house (the temperature of the chicken house is not high, under normal circumstances, still have a part of the broiler's mouth, not the high temperature, but the big negative pressure in the chicken house, the pressure gas and the broiler anoxia).

通风环节中需要注意的细节：

Attention should be paid to the details in the ventilation link.

1、用通风管通风时，要检查鸡舍有无漏风地方：水帘要严密封闭：窗户要严密封闭；墙体无漏风直吹鸡的缝隙；大排风机用塑料布封严；进入鸡舍的PVC管斜向上，最好末端劈成45度斜角；1-30天鸡舍后面必须有两层塑料布遮挡并且塑料布左、右与墙体，塑料布下面与鸡架密闭良好。

1, when ventilating with a ventilator, check the air leakage of the chicken house: the curtain should be closed closely: the window should be closed closely; the wall has no air leakage and the chicken's crevice; the large exhaust fan is sealed with plastic; the PVC pipe entering the chicken house is inclined upward, the best end is split into 45 degrees angle; and the 1-30 days of the chicken house must be covered with two layers of plastic cover and cover the rear of the chicken house and cover the rear of the chicken house for 1-30 days and And plastic cloth left, right and wall, under the plastic cloth and chicken rack closed well.

2、通风管直径最好在20厘米以上，每隔2-3米远安装一根，打孔处位于网架边缘高50厘米以上，一面墙体以一米、两米、三米交错按序安装，对面墙体以三米、两米、一米交错按序安装。

2, the ventilation pipe diameter is better than 20 centimeters, each 2-3 meters far installed, the hole located at the edge of the grid is 50 centimeters high, one meter, two meters, three meters in a staggered sequence installation, the opposite wall to three meters, two meters, one meter staggered installment.

3、通风管内冷空气进入鸡舍一定要和鸡舍上方的热空气混合后再缓慢落下，落下后接触鸡的空气温度要满足该日龄所需正常温度，不要低于该日龄所需正常温度，避免冷风吹鸡，造成冷应激。

3, the air into the chicken house must be mixed with the hot air above the chicken house and then drop slowly. The air temperature of the chicken will meet the normal temperature of the day, and it should not be lower than the normal temperature of the day, avoiding the cold wind and the cold stress.

4、根据鸡舍内温度和风机个数来确定通风管开启数量，以先开启长通风管再开启短通风管的顺序(三米-两米-一米)。按肉鸡体重的逐渐增加合理依次开启。

4, according to the temperature in the chicken house and the number of the fan to determine the number of ventilation pipe to open, in order to open the long vent pipe and then open the short duct order (three meters - two meters - one meter). According to the gradual increase of the weight of broilers, they were opened in a reasonable order.

5、刮大风时，注意关闭全部或多数的迎风向PVC通风管。

5, when blowing strong winds, be careful to close all or most of the windward PVC ventilation pipes.

通风管通风需要的效果评估：感官判断：1、鸡舍空气清新、不闷、不压气、氨气味小或无。2、鸡舍内灰尘很少、无蜘蛛网。3、通风管下方，用手背或光膀子蹲在鸡架上感觉不冷，以肉鸡群鸡背上方无冷风，温度合理，无冷应激为标准。

Effect evaluation of ventilation pipe ventilation: sensory judgement: 1. The henhouse is clean, unstuffy, not compressed, and ammonia is small or not. 2, there are few dust in the chicken house and no spider web. 3. Under the ventilating pipe, squatting on the chicken rack with the back of the hand or the bare arm is not cold. The chicken has no cold air above the back of the chicken, the temperature is reasonable, and there is no cold stress as the standard.

关于PVC通风管与排风机如何合理、科学的配合使用，就需要养殖朋友自己慢慢摸索出适合自己鸡舍的一套方法了。（有的按最小通风量来通风；有的按所设下线温度控制排风机开启与关闭来通风；有的PVC通风管配合侧风机来通风；有的PVC通风管配合纵向风机来通风；有的把上诉方法结合起来通风；或其他等方法）凡是肉鸡能够到日龄正常出栏，料肉比在合理范围内的方法都是可行的。

With regard to how to use PVC ventilator and exhaust fan reasonably and scientifically, it is necessary for farming friends to find out a suitable method for their own henhouse. (some are ventilated according to the minimum ventilation amount; some are controlled by the set down temperature to open and close the ventilator; some PVC ventilation pipes are ventilated with the side fan; some PVC ventilation pipes are ventilated with the longitudinal fan; some are ventilated with the appeals method; or other methods) all the broilers can be normal to the age of age. It is feasible to slaughter raw materials in a reasonable range.

合理应用PVC通风管很重要，一定要科学的应用。通风的好坏，关系到这批鸡是否饲养成功的一个很重要因素；关系到这批鸡料肉比高低的一个重要因素；也关系到这批鸡挣钱多少的一个重要因素。

Reasonable application of PVC ventilation pipe is very important and must be applied scientifically. The good or bad ventilation is an important factor in the success of the chickens; it relates to an important factor in the ratio of the meat and meat to this batch of chicken meat, and is also an important factor in the amount of money the chickens earn.
