Causes and control of malformed cucumber
The formation of cucumber malformed melon greatly affects its commodity quality and economic benefits. In order to solve this problem, it is necessary to understand the causes of common malformed cucumber and its control measures.
First, pointed melon
The pointed melon, also known as the pointed melon, is a common type of malformed cucumber. Mainly caused by the following factors:
1. Cucumber is weakly parthenocarpic and female flowers are not fertilized during flowering. Because the ones are weak and weak, they are generally difficult to develop on their own, and because the female flowers are not fertilized, the seeds cannot be formed in the fruit, and the motive force that promotes the transportation of nutrients to the fruit is lacking, thus causing the fruit to be malnourished and forming a pointed melon. . Control measures: Create good pollination conditions during the flowering stage of cucumber, such as beekeeping and artificial pollination.
2. In the early stage of plant growth, the supply of nitrogen fertilizer is insufficient, which makes the stems of the plants thin and tough, and also produces pointed melons. Control measures: Apply fertilizers with high nitrogen content such as urea.
3, the plant growth potential is weak, especially in the late stage of fruit enlargement, insufficient fertilizer and water, so that the normal nutrient supply can not be obtained in the fruit. Control measures: ensure that sufficient mineral nutrients are transported to the fruit.
Second, big belly melon
This is also a common type of malformed cucumber, the main reasons for which are:
1. Cucumber female flowers are incompletely fertilized, and only seeds are produced at the apex of the melons, resulting in a particularly large flesh of the apex pulp, which is a large belly head. Control measures: create good conditions for flowering and pollination.
2, the plant is deficient in potassium and excessive nitrogen fertilizer, it will also produce big belly melon. Control measures: Apply potassium nitrate, plant ash, etc., or spray 0.3% potassium dihydrogen phosphate solution on the foliage of the plant.
3, the lack of water in the early stage of cucumber growth, and a large amount of water supply in the later period, will also produce big belly melon. This is because water has a strong influence on the growth of cells. When water is scarce, the cells grow slowly. When a large amount of water is supplied, the cells develop rapidly. Control measures: Balance the water supply throughout the growing season, keep the soil wet, and avoid excessive drought and water shortage or flood irrigation.
Third, curved melon
Cucumber fertilization is incomplete, and only the egg cells on the side of the ovary are fertilized, resulting in an unbalanced development of the entire fruit.
1. During the growth of cucumber, curved melons are produced by factors such as high temperature, high humidity and bad weather. Control measures: Take a toothpick, tie it on the cucumber vine that produces the curved melon, and then pour the water again. The next day, the melon can be straightened. At this time, the fine toothpick can be pulled out and the cucumber can still grow normally.
2. During the growth process, the cucumber is blocked by the foreign object and cannot be stretched normally, resulting in deformed bending. Control measures: After the cucumber is placed on the melon, remove the foreign matter that blocks the growth of the cucumber, so that the cucumber is normally elongated.
Fourth, bee waist melon
Cucumber female flowers are incompletely pollinated and easily develop into bee waist melons. After the cucumber is pollinated, the supply of nutrients in the plant is insufficient, and the dry matter accumulation is small, and it is easy to form a bee waist melon. Control measures: Strengthen nutrition, especially during the fruit setting period, increase the supply of fertilizer and water to ensure sufficient nutrient accumulation.
