In the recent production, many cucumbers have dull and dull colors and have poor brightness, which seriously affects the value of commodities. What causes this?
If the phenomenon that the melon strips do not appear from the beginning of the root melon, it should be considered whether the rootstock selection is appropriate. The brightness of cucumber depends mainly on the ability of rootstock to remove wax. Commonly used rootstocks are mainly white pumpkin seeds and black pumpkin seeds. White pumpkin seeds are also divided into small seeds and big seeds. Among them, white pumpkin seeds are dewaxed. Powder is best. The dark-skinned squash has poor wax-removing power, and the surface of the squash is covered with a layer of wax powder. The melon surface is white and the brightness is poor. When selecting rootstocks, choose white-seed pumpkin varieties with high purity and strong wax removal power.
For the normal growth of the early stage melons, and the late appearance of the melon surface is not bright, the following two reasons should be considered.
The first is whether the scion cucumber is rooted again. After grafting and cutting off the roots of the cucumber, under the high temperature and humidity conditions of the greenhouse, the secondary roots are easily sprouted next to the grafted joints, and they will stick into the soil as time goes by. This will reduce the wax removal of the white-seed pumpkin. Ability to influence the color of melons. During the growth of cucumber, it is necessary to promptly check and cut off the new root of the grafted cucumber.
The second is whether the temperature and fertilizer management are appropriate. In winter, the greenhouse temperature is relatively low, affecting the absorption of nutrients by the root system, especially the absorption of trace elements in the roots, which may cause melons to glow. In daily management, it is necessary to pay attention to rational watering and fertilization. You can use good water-soluble fertilizers such as Lipu and Fangrun, and use Apollo 963 root-raising element, root good, etc., and regulate the temperature to avoid the above situations.
