All along, when vegetables are grown on a vegetable cover line, they are all arched, that is, they are supported by bamboo poles or iron wire to form a small arch. The purpose of doing so is to facilitate the smooth watering under the membrane, the second is to help increase the temperature in the cold season. However, in the past two years, drip irrigation has gradually been used in some greenhouses, which is certainly worth promoting. But at the same time, the reporter found that some vegetable growers no longer arched when they were covered with drip irrigation and watering on the cucumber planting line, and they directly covered it on the planting line and allowed it to be attached to the land. The reporter believes that there are drawbacks in this practice and hopes that the farmers will correct it immediately. Why do you say this? The reason is very simple, although the installation of drip irrigation in the line, no longer need to water under the membrane. But after all, there is a benefit after the film is arched. It is to increase the temperature. Most of the growing seasons of autumn quinoa and winter glutinous vegetables are in the cold season, the temperature is low, and the temperature is not high naturally. If the mulch film on the planting line is arched, the ground temperature in this “small arch shed†will inevitably be much higher than the direct ground cover, and the vegetables will grow faster and produce more output. Maybe some farmers would disapprove of it, thinking that the temperature difference between the arches would not be much. Then you were wrong. A vegetable farmer had experimented. The earth temperature under the bulging arch and the undulating plastic film was at least 5°C during the day. If you don't believe it, you can measure it yourself with a thermometer. In the winter, what is the concept of a 5°C difference in ground temperature? It must have been clear to the heart of a vegetable farmer. Therefore, from now on, we must attach great importance to this matter. After all, when vegetables cover the mulch after planting, it will not cost much to increase the cost of the veil, but it will not be very troublesome. But it can play a big role. Not fun for it?
