Recently, a farmer friend asked why cucumbers are curved. Curved cucumber grows slowly, and although it also expands and enlarges, it reduces the yield of normal straight cucumbers, and reduces income due to poor quality.
According to a multi-point investigation and analysis, there are many reasons for the appearance of crooked cucumbers in cucumbers: First, some farmers are worried that the excessive vegetative growth of cucumbers in early stages will affect the growth of fruits, excessively control the water and nutrients, make the supply of fertilizer and water to the plants insufficient, and the development of young larvae This situation mostly occurred in the early stages of fruiting melon; second, partial application of nitrogen fertilizer and phosphate fertilizer, lack of large amounts of elemental potassium fertilizer and trace element boron fertilizer, so that the female flower development is not complete; the third is the previous removal of excessive leaves, or the field of melons, The slings, such as slings, that support the climbing of cucumbers and vines affect the elongation of the young cucumis; fourth, the flowering season encounters strong winds or continuous low temperature and rain, or lack of light, which causes poor fertilization of female flowers; Fifth, it is harmed by pests and diseases. It is very easy to bend at the affected part.
In order to improve the status of cucumber cucurbits and increase yield and quality, field management centered on fertilizer and water must be strengthened.
First of all, finely divide fertilizer and water management. The yield of cucumber is high, and it requires a large amount of fertilizer. However, it has a shallow root system and weak ability to absorb fertilizer and water. It is also a melon crop harvested by stages. The management of fertilizer and water must be completed in several stages. After transplanting cucumber seedlings, a small amount of planting water stable seedlings should be poured. The melon period should be followed by a fertilizer every 10 days or so. Alternately, the human feces and fertilizers can be used alternately. In the period of fruiting, appropriate quantities of chemical fertilizers should be applied. Special attention should be paid to the application of potassium sulfate fertilizer. At the same time, in combination with pest control, 0.3%-0.5% of urea and 0.2% of potassium dihydrogen phosphate were sprayed twice at the root, and boron-deficient soil should be sprayed with 0.1%-0.2% of sulphur twice. Watering should be carried out in the morning on a sunny day, and watering in the fields in the evening can cause diseases due to high humidity. After picking the melon should not be too much watering to avoid madness. In the middle and late stages, avoid flooding and prevent rot or blight from spreading.
Second, adjust the bracket to improve ventilation and light transmission. Cucumbers have the habit of climbing. Management uses bamboos to insert into the soil in a herringbone or trapezoidal shape to create high-yield living space conditions for the growth and development of cucumbers. At the same time, they use plastic ropes to fasten the "tap", and the time is usually adjusted once a week. The height of the "leading" should be basically the same, and the main branches of the melon should be removed immediately. The females with more collateral female flowers can retain 1-2 female flowers in the lateral branches. At the same time, the old leaves, diseased leaves, and excess tendrils in the lower part of the plant were randomly removed. In this way, the growth of cucumbers will be unimpeded and the permeability will increase.
Third, the dredging of the field ditch lowers the groundwater level. Cucumber likes water but is afraid of waterlogging. Poor drainage will increase the humidity in the field, and the root system will be damaged. At the same time, the humidity will breed diseases. Therefore, we often need to manage the gutters and remove the water in a timely manner to reduce the groundwater level to 1. Below m, promote cucumber root growth, improve resistance to stress.
