Soil moisture is a necessary external factor for crop growth. Different crops and watering during different growth periods are characterized by regularity and need to be determined according to actual conditions. Taking cucumber as an example, on the basis of ordinary pouring water, each plant will be planted with 1.5 to Zkg of planting water, and 5 to 7 days after planting, the plant will be irrigated with osmotic water, and about 70% to 80% of plant roots will grow long. To about 10cm, the melons are blackened, and the melons are quickly watered when they grow rapidly. This way of watering depends to a great extent on empirical judgment and is not suitable for modern precision agriculture. For this reason, if a soil moisture measuring instrument is used to measure and analyze soil moisture, then the watering measures will be more accurate, and it will be more conducive to the growth of the crop.
After measuring the soil moisture by a soil moisture quick tester, if the water content is good, the water in this period can be extended to watering before root melon harvesting. If the melon plants are dwarf, the amount of transpiration of the leaves is small, the number of melons is also small, and the ventilation is also small. Usually, the water is poured once every 5 to 7 days, and the water must be poured under the membrane; the transpiration of the melons increases as the amount of transpiration increases. The number of results increased, ventilation increased, usually 3 to 4 days, pouring water, and increase the amount of water; tail melon plants tend to aging, should reduce the number of watering and watering as appropriate.
Greenhouse greenhouses play an important role in modern agricultural cultivation. In terms of greenhouse vegetables, high temperature, high humidity, or low temperature and high humidity are all important causes of the occurrence and spread of vegetable diseases. The traditional method of flood irrigation is used. It is easy to cool and increase humidity. Therefore, in the greenhouse vegetable growing process, the soil moisture quickness meter has a very important guiding role in the determination of soil-related moisture content. Normally, the water temperature is required to be as close as possible to the local temperature, and it is generally best to use well water for irrigation. Avoid using river water or cold water in the pond.
