Cucumber is a common vegetable variety in our lives. Cucumber is highly adaptable, and many farmers like to plant it. However, some farmers do not pay attention to the balanced application of nutrients and the influence of soil conditions when planting cucumbers. Especially in the case of high temperature and high humidity in summer, cucumbers are prone to rotten roots and dead tops. Tell me about the common methods of controlling cucumber diseases. 1. Cucumber dead roots, rotten roots, weak roots The main reason is that the roots are damaged when the cucumber is transplanted, it is difficult to regenerate after the root is damaged, the absorption capacity is poor or the soil is compacted, the gas permeability is poor, and the soil alkaline film is fertilized by ammonia burning. Control points: (1) Choose loose and rich organic soil to maintain the permeability of the soil. (2) Increase the soil organic matter and beneficial bacteria, apply 150 to 200 kilograms of organic bacterial fertilizer per acre, and apply heart-to-heart humic acid water-soluble fertilizer in the growth stage of cucumber for 5 days per acre. 2, cucumber "fat weak", "top dry" Mainly due to excessive application of nitrogen fertilizer, as well as high temperature and rain, the shape of the upper leaf is small, and the edge of the top edge of the cucumber vine is curled and dead. Control points: (1) Reduce the application of a large amount of nitrogen fertilizer, watering at the right time to ensure sufficient water. (2) Apply micro-element water-soluble fertilizer (calcium-containing element), apply 5 kg once every 20 days or spray through the foliage. 3, cucumber melon strip is not straight, the yield is reduced The main reason is the high temperature and dry weather in the fruiting stage of cucumber flowering, or the uneven melon strips such as short, small, big belly melon and pointed melon caused by insufficient potassium nutrient. Control points: (1) Ensure soil moisture supply at the right time. (2) Ensure the supply of soil potassium fertilizer and calcium fertilizer, and ensure that 5 kg per mu is mixed with high potassium water soluble fertilizer and medium and trace element water soluble fertilizer before and after harvesting. 4, premature aging of cucumber, decreased yield Mainly because of high temperature, poor soil permeability, phytotoxicity and insufficient supply of trace elements in the fruiting period, the supply of magnesium and zinc is insufficient, and the leaves turn yellow, the plants shrink, the fruit grows slowly, and the lower parts are more deformed. Control points: (1) Ensure the permeability of the soil, do not over-watering to cause damage. (2) To ensure the supply of trace elements in the middle and the high-potassium water-soluble fertilizer and the medium-micro-element water-soluble fertilizer before and after the melon is mixed, 5 kg per mu. The above is the common disease of summer cucumber and its prevention and treatment method compiled by Huinong. I have learned it?
