Aren't the old farmers afraid of drowning cucumbers instead of draining the cucumber garden after the heavy rain?

The heavier the rain, the more cucumbers need to be watered. Such a view does not seem to stand up to scrutiny. This sentence should be correctly understood. From the point of view of many netizens on the Internet, because the heavy rain will submerge the cucumber, if it is soaked in the soil for a long time, it will suffocate due to the lack of oxygen in the cucumber root system, affecting the growth and development of the cucumber.

The irrigated water itself carries a considerable amount of oxygen. Pouring fresh water after the heavy rain has discharged Rain Water can make the root system rejuvenate and continue to grow! And the meaning of this I want to emphasize is drainage and oxygen exchange rather than watering! Watering is a measure, not an end!

If only from the surface of this sentence is not found, after watering, the soil will be submerged in the soil again, and the cucumber will fall back into a lack of oxygen? There is a great possibility! Therefore, after the rainstorm, watering is not the first choice. Science should first drain the water, and then loosen the soil.

Draining water

In fact, there are relatively few cases of waterlogging in the north, but there are a lot of waterlogging in the south. There will be heavy rain in two or three days. at this time, the first thing we should pay attention to is to do a good job of drainage in time after the heavy rain, so as to avoid the disturbance of root respiration caused by waterlogging in cucumber fields.

In terms of cultivation, Scientific Xingnong also suggests that we should adopt the plan of planting cucumbers from Gaolong when planting cucumbers, so that even if there is heavy rain, it will not cause excessive waterlogging to cucumbers. At the same time, Rain Water will flow out of the farmland along the ditch to avoid causing waterlogging in the deep ditch under Longxia.

Loose soil

First of all, the purpose of loosening the soil is to increase the air permeability of the soil, provide more oxygen for the roots, and make the root breathing more unobstructed; secondly, apart from loosening the soil, the weeds on the surface can also be cleaned up, which can be said to kill two birds with one stone.

As far as loosening soil is concerned, this is also a big choice after waterlogging, which is also called drying soil moisture in some places, so that the water content in the soil can be reduced rapidly, which is very helpful to improve soil permeability and soil nutrient utilization efficiency.

To sum up, the scientific development of agriculture does not agree with the so-called plan of quickly watering after torrential rain, which has no scientific basis. After heavy rain and waterlogging, do not rush to water, what is needed is drainage and loosening soil.

Here is science to promote agriculture, welcome to add attention, with you to grow knowledge.
