近年来,呼和浩特市郊区利用塑料大棚提早生产黄瓜,用蜂窝煤防冻已被菜农采用,并取得了一定的效果。但是部分菜农还没有掌握防冻的方法,吃了冻害的苦头。为使广大的菜农更好的掌握防冻的方法。现介绍三招措施。一、风窝煤在大棚内安放的部位根据我站多年观测和实践,一般1亩大的塑料大棚把蜂窝煤放在大棚的四周,距离棚边2米为好。蜂窝煤数量的多少,应根据天气的变化降温的强度而定。一般晚间最低温度在零下4度左右时,按放6—8个蜂窝煤点,每点12块蜂窝煤。
In recent years, the outskirts of Hohhot early production of plastic greenhouses cucumbers, with honeycomb antifreeze farmers have adopted, and achieved some results. However, some vegetable farmers have not yet mastered the antifreeze method and ate the frost damage. In order for the majority of vegetable farmers better grasp the method of antifreeze. Now introduce three measures. First, the wind briquettes placed in the shed parts According to my station for many years of observation and practice, the general 1-acre plastic shed to briquettes around the shed, 2 meters away from the shed as well. The number of briquettes should be based on the intensity of the cooling changes. The general evening minimum temperature of about minus 4 degrees, press release 6-8 honeycomb points, each point 12 briquettes.
