"I had a lot of wilts in the summer cucumbers I planted in June, and I have serious problems in places where water can easily accumulate. How to solve this problem." During an interview with the reporter on the Gucheng Street in Shouguang City, reporter Liu Zhongsheng asked the reporter.

Master Liu's gherkin has been 13 days since it was planted until June 18th, because the cucumber has been exposed to dry hot air during the colonization and the temperature inside the greenhouse is high. After the watering, the soil dries quickly. In order to prevent the lack of cucumber in the shed, but also to reduce In the greenhouse temperature, he took a method of diligent watering and watered it 4 times in 13 days. It is understood that Master Liu watering was completed before 9 o'clock, and because watering was too busy, it also caused serious water accumulation in many places in the shed.

To understand the answer more accurately, the reporter briefly tested Liu's temperature and soil temperature. The test results are as follows: 9 points (that is, the time when Master Liu watered off), the temperature in Master Liu's greenhouse is 28°C, the soil temperature is 5° to 6cm, and the ground temperature is 26°C; and the temperature of the well water used for watering At around 14°C.

Knowing this, the reasons for the wilting of the cucumber planted by Master Liu also surfaced. The first was water-cooled, deep-fried roots, and the other was the roots of the water.

Because the temperature difference between the water temperature and the ground temperature is relatively large, each watering will cause the cucumber to have a certain degree of deep-fried roots, and Master Liu pours water every 4 days. When the root system of the cucumber has not recovered, the phenomenon of deep-fried roots occurs again. As a result, the function of the cucumber root is reduced, and the absorbed water cannot satisfy the need of transpiration, thereby causing wilting. Due to the accumulation of stagnant water in the shed, the suffocation of roots caused anoxia and rooting occurred, adding to the degree of wilting.

Then, how can a vegetable farmer be suitable for watering when planting summer cucumbers? The author believes that when the farmers are planting cucumbers, the first water should be completely immersed in the operation line and planting line. When the interval is about 4 days, the vegetable farmers should pour the second water in time, that is, easing the seedling water. This water only Just plant the plant. After pouring the osmotic water, the vegetable farmer should pay attention to timely ploughing, thereby cutting off the soil capillary, reducing the evaporation of soil moisture, in order to extend the watering interval to 7-8 days, which is conducive to the cucumber root system. The growth. When pouring the third water, the vegetable farmer can only pour small water, and pay attention to timely scratching. It is necessary to pay special attention to the fact that the current watering should be completed before 8 o'clock, so that the ground temperature is close to the water temperature, not to cool the roots. Before the cucumbers were poured into the fourth water, when the cucumbers were planted for about half a month, the vegetable growers started to hang the cucumbers. The roots of the cucumbers had grown bigger and deeper. The stems and leaves on the ground also formed shade on the ground. Because the sun can not directly make the evaporation of soil moisture reduced, so even without scratching, cucumber watering interval can reach about 7 days, and the planting ground temperature is maintained within the range of about 25 °C, vegetable farmers can Appropriately relax the last time limit of watering, but it is better to finish before 8 o'clock so that the chance of deep-fried roots of cucumbers will be greatly reduced. But also be careful not to water.
