Greenhouse thermometer has exquisite

At present, most farmers for PengShi temperature monitoring relies mainly on the suspension of greenhouse thermometer on the wire, and the position of the thermometer suspension and height is not random, more is not fixed. The temperature of the main function is able to reflect the vegetables leaf as the best monitoring temperature. So, different height of vegetables position is different, its function leaf area with the growth of plants, temperature monitoring location will change too. Vegetables mainly the function of the upper leaf area refers to the three young leaf, lower more than three leaflets of leaf area, leaf development mature, the region most photosynthetic capacity, is a major place of synthetic organic nutrition, therefore, control the temperature of the region to make vegetable quality is better, more productive. So, PengShi the suspension of the thermometer, not higher than the plant growing point, also cannot be under fresh mouth, and to hang in the PengShi near the middle of the position ( North and south) In hundred meters PengShi suggest hanging 3 root, hundred meters PengShi hanging 4 - 5 root. Thermometer hanging high up, with the growth of plants and constantly during seedling, the thermometer can be hanging in the upper part of the plant, when the plants grow to 40 cm, thermometer to hang in the upper position in the plant, with the growth of plants, thermometer, ensure that the position of the thermometer in the plant leaf area in the middle or upper function. The temperature monitoring is accurate. Thermometer, moreover, the best hanging in the planting industry, or can also be planted close to the line, if the operating line, thermometer by sun exposure can lead to errors.
