The formation of cucumber malformed melon greatly affects the quality of its products and economic benefits. To solve this problem, it is necessary to understand the causes of common malformed cucumbers and their prevention and control measures.
1. Tip Tips Tip Tips are also commonly known as malformed cucumbers. Mainly caused by the following factors:
1. The cucumbers are weakly parthenocarpic and the female flowers at the flowering stage are not fertilized. Because of weak unisexual varieties, it is generally difficult to grow fruit on their own, and because the female flower is not fertilized, seeds cannot be formed in the fruit, and the original driving force for the transportation of nutrients to the fruit is lacking. . Prevention and control measures: To create good pollination conditions during the flowering period of cucumber, such as bee feeding and artificial pollination.
2. In the early stage of plant growth, the supply of nitrogen fertilizer is insufficient, which makes the plant stems fine and tough, as well as cantaloupe. Control measures: Apply fertilizers with high nitrogen content such as urea.
3. The growth potential of the plants is weak, especially in the late stage of fruit enlargement. The lack of fertilizer and water makes it impossible to obtain normal nutrient supply in the fruits. Control measures: Ensure that there is sufficient mineral nutrients transported to the fruit.
Second, Daduguagua This is a common type of abnormal cucumber, the main causes of formation are:
1, cucumber female flower insemination is incomplete, only in the melon's apex to produce seeds, leading to apex pulp special tissue hypertrophy, was potbellied head. Control measures: Create good conditions for flowering and pollination.
2, plant potassium deficiency and excessive nitrogen fertilizer, will also produce big guagua. Control measures: Apply potassium nitrate, ash, etc., or apply 0.3% potassium dihydrogen phosphate solution to spray the leaves of plants.
3, cucumber lack of water in the early growth period, and a large number of water supply in the later period, will also produce big guagua. This is because water has a strong influence on the growth of cells. In the absence of water, cells grow slowly. When water is supplied in large quantities, cells develop rapidly. Control measures: A balanced water supply during the whole growing season, keeping the soil wet, and avoiding excessive drought or water flooding.
Third, the curved melon cucumber fertilization is not complete, only the ovary side of the egg fertilization, resulting in the entire fruit development is unbalanced into curved melon.
1. During the growth of cucumbers, the melons are produced by the influence of high temperature, high humidity, and bad weather. Preventive measures: Take a toothpick, tie in the cucumber vines that produce curved melon parts, and then pour water again. The melon strips can be straightened the next day. At this time, the fine toothpick will be pulled out and the cucumbers will still grow normally.
2. In the process of growth, cucumber is blocked by foreign matter and cannot stretch properly, resulting in malformed bending. Prevention and control measures: After the cucumber is sitting on the melon, the foreign material that blocks the growth of the cucumber is removed and the cucumber is normally elongated.
Fourth, the beeswax cucumber female flower pollen is not complete, easy to develop into a beak waist melon. After the cucumber is pollinated, the nutrient supply in the plant is insufficient, dry matter accumulation is less, and it is easy to form bee loincloth.
Preventive measures: Strengthen nutrition, especially in the fruit setting period, increase the supply of fertilizer and water, and ensure that there is sufficient accumulation of nutrients.
