Ridge cultivation can be widely used by vegetable growers in recent years due to its ability to increase ground temperature, increase soil permeability, and promote the growth of vegetable roots. In vegetable ridge cultivation, the ridge height is appropriate, and most of the vegetable growers are upset.
Many vegetable farmers believe that the higher the ridge is, the better the vegetables are. Some farmers even set the ridge height to 40-60 cm. This practice is wrong. When the ridge is too high, it can significantly increase the temperature of the ground and the permeability of the soil, but watering becomes a problem. If there is too little watering, the water will not flood the ridge, and the moisture needed for normal vegetable growth will not be guaranteed. If watering is too much, the water in the field will take a long time, which will easily cause the roots and germs of the vegetables to spread, causing the vegetables to rot. . Is it right? When the ridge is too low, a little more watering will diffuse over the roof of the ridge, and the ridge roof will be impregnated, making it impossible for ridge cultivation to increase the permeability of the soil.
In the ridge cultivation, the most reasonable ridge height? The author believes that under normal circumstances, ridge height is about 25 cm more appropriate. If the water flowing southwards of the greenhouse is not very smooth, increase the ridge height to 30 cm to prevent the water in the ditch from flowing over the ridge roof; if the water flowing southward from the greenhouse is very smooth, the ridge height can be reduced to 20 cm. In order to prevent the water within the ditch from reaching the top of the ridge, the ridge surface is too dry, which affects the growth of vegetables. In short, the standard that should be mastered is that the water depth should reach 2/3 of the ridge height when watering, so that ridge cultivation can exert its proper effect.
