Suitable for ridge cultivation of vegetables
Rib cultivation is widely used by vegetable growers in recent years due to its ability to increase ground temperature, increase soil permeability, and promote root growth of vegetables. In vegetable ridge cultivation, the ridge height is appropriate, and most of the vegetable growers are upset. Therefore, ridging often occurs too high or too low in production.
Some farmers think that the higher the ridge, the better, some farmers even set the ridge height at 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. When the watering is too little, the water can not reach the ridge and the moisture needed for the normal growth of the vegetables cannot be guaranteed. If the watering is too long, 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 and die. When the ridge is too low, a little more watering will diffuse over the ridge roof, and the ridge roof will be impregnated, making it impossible for ridge cultivation to enhance soil permeability. It can be seen that high or low ridges are not conducive to vegetable production. Therefore, in order to make ridging cultivation really play its due role, the ridge height should be set reasonably.
Then, how much more reasonable is the ridge height in ridge cultivation? 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 in the ditch from filling the ridge roof, 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.
