Experienced cucumber cultivators often judge whether the management is appropriate through the external morphological characteristics of cucumber plants, and formulate the basis for scientific management based on the appearance of cucumbers. Overwintering of cucumbers takes a long time, and abnormal appearance often occurs during the result period. Judging from the shape of the melons and the opening of the female flowers, it is judged whether the cucumbers are normal. The normal position of cucumber during flowering period is 40 to 50 cm from the top of the plant, and the melon strip to be harvested is 80 to 90 cm from the top of the plant. During the period, there are 6 to 7 pieces of expanded leaves, which are abnormal under or above the standard. . If the flowering node is more than 50 centimeters away from the top of the plant, it is a performance of the plants. The plant type is formed in the case of sufficient fertilizer and water, excessive nitrogen fertilizer application, poor sunshine, and high night temperature. For this type of greenhouse cucumber management to increase the temperature difference between day and night, to maintain the night temperature of 12 °C ~ 15 °C, the early cover of the opacity covering grass cover and other cover to increase the light within the shed, while controlling the amount of nitrogen fertilizer, and by combining the whole vine Make growth point flat to adjust growth. Winter cucumbers are prone to growth failure during production. If the flowering node is less than 40 cm from the growing point, the melon part is closer to the top than the old one. It is due to the lack of nutrients, water supply, or supply of nutrients but the roots of the plant can not be absorbed normally due to fatigue of the squash, is a manifestation of the growing weakness of the plant. In severe cases, the flowering node reaches the top of the vine, and the flower is topping. This indicates that the nutrition of the plant is extremely weak, and this phenomenon occurs when the soil is too wet, too dry, low temperature, and the root system is weak or damaged. Cucumbers that have been debilitating should be promoted by roots. To improve the temperature inside the shed, in particular to strengthen the night insulation, to maintain the night temperature of 15 °C ~ 18 °C, to properly eliminate some of the young melon and female flowers; to apply topdressing nitrogen fertilizer and humic acid type of fertilizing materials; to spray leaf surface Fertilizer (such as Tianda 2116, calcium magnesium foliar fertilizer, too fat, etc.) or regulators (such as Yunda-120, chitin, etc.). The slow growth of melon and guarana is the most common physiological disease phenomenon during the overwintering cucumber period. It is mainly due to insufficient nutrients, low temperature and low light, high temperature during the day and night, excessive reproductive growth, excessive number of female flowers, too dense yards, overburdened plants, and competition among various organs for nutrients. In management, while strengthening the management of temperature, fertilizer, and water, reasonable flowering and fruit retention, adjusting the ratio of leaf to fruit between 2 and 3, artificial pollination or Paul Gualing treatment to ensure fruit set and accelerating melon strip expansion. The increase of malformed melons is also a sign of declining growth. At this time, it is necessary to strengthen the management of fertilizers and waters in order to maintain the roots, and to supplement the foliar fertilizers in a timely manner to supplement the deficiency of nutrients. Looking at female flowers can also diagnose whether cucumber growth is normal. The normal female flowers are large and long, and the downward opening is normal; the female flowers of the cucumber open horizontally, indicating that the growth of the plants is relatively weak; the opening of the cucumber female flowers upwards indicates that the growth potential of the plants is very weak. In the production of cucumber, we must observe and adjust the plant growth and flowering results as well as the length of the female melon in order to formulate scientific and reasonable management methods according to the situation to maintain the robust growth of cucumber and achieve high yield and quality of cucumber.
