Cucumber cultivation techniques: what is cucumber flower topping?

What is the topping of cucumber flowers? What harm does cucumber flower top have? Also ask experienced netizens to help introduce and guide the harm of cucumber flower topping and prevention methods can refer to the following list. The cause and harm of cucumber flower topping: if cucumber is not managed properly in early spring, late autumn or winter, it is very easy to burn root, rett root, low temperature at night and damage to root system, which will lead to the phenomenon of flower topping in cucumber. As a result, the cucumber can not blossom normally. Prevention and control methods of cucumber flower topping: daily reasonable watering, so that the soil water holding capacity reaches 22%, relative humidity reaches 65%, ploughing in time after watering, in order to strengthen ground temperature management, raise the ground temperature to more than 12 ℃ as soon as possible to prevent root burning or retting. It is found that when the root system appears gray-white water stains, stop watering, ploughing in time, and if necessary, dig ditches to dry the soil, increase the soil temperature and reduce the soil water content as much as possible. At the same time, the fruited melons were removed to reduce nutrient consumption and promote root growth. The temperature in the first half of the night in the greenhouse reached 15 ℃ and lasted for 4-5 hours, and the temperature was kept at about 10 ℃ in the second half of the night. When it is too low, the new high lipid film should be evenly sprayed on the plant and the ground, and the protective film should be formed rapidly, which can absorb heat and increase temperature, preserve soil moisture and seedlings, maintain the degree of soil and greenhouse, increase effective accumulated temperature to restrain water evaporation, improve water use efficiency, improve soil ventilation capacity, purify soil environment, improve crop growth environment, and increase soil organic matter. Inhibit the reproduction of soil diseases and insect pests. Pay attention to less root damage when ploughing, and take measures to protect seedlings and roots in time. In order to prevent the influence of water and malnutrition on root growth, vegetable and fruit Zhuangtieling was sprayed once before flowering, young fruit stage and fruit expansion stage of cucumber, and the nutrient water supply was increased by adding thick cucumber nutrition transport conduit to meet the physiological needs of fruit development. strong seedlings, balanced nutrition matching, strengthen photosynthesis, avoid the phenomenon of flower topping with nutritional disorders.
