In the winter greenhouse cucumber production, there are many kinds of physiological diseases of cucumber fruit, mainly including curved melon, thin waist melon, big belly, melon, melon, melon, zucchini, bitter melon and so on. There are two main reasons for the cucumber melon: First, because the cultivation techniques are not in place, the management is extensive, especially in the flower bud differentiation period, which is affected by some measures. After the fruit is expanded, the melon is formed. Second, the cucumber is growing. During the development process, it is formed by various physiological obstacles (including temperature, moisture, light, gas, fertilizer barrier) and hormone poisoning. In addition, continuous cultivation, adversity cultivation, improper application of pesticides, etc. can also lead to the emergence of physiological gems. Once this happens, not only is the yield and quality of the cucumber reduced, the commodity is poor, and there is a large economic loss in production. Therefore, this special issue issued a technical article on the prevention and control of cucumber melons written by Liu Daoxiu, the agricultural service center of Qiaolou Township, Ningling County, for readers' reference.

Forming reasons Linyi Fertilizer Network Copyright

A strange - curved melon Linyi fertilizer network copyright
Linyi Fertilizer Network Copyright
It is manifested as a ring-shaped bend from the melon stage. Causes of formation: When the inflorescence begins to develop, it encounters continuous yin weather, continuous low temperature, insufficient light, and lack of nutrient water, which makes the growth of cucumber seedlings bend, which makes the formation of juveniles extremely easy to bend; or due to high temperature management, nutrient excess water It causes the growth of stems and leaves to flourish. Even if the plant grows normally, if a seat is too much, it will form a curved melon. Linyi Fertilizer Network Copyright

Second blame - zombie Linyi Fertilizer Network Copyright

It is characterized by the uniformity of the melon strips, the short melon strips, the less moisture of the melon meat, and the dullness of the melon skin. The reason for the formation: the first water is poured too early after the seedlings are delayed, the seedlings grow too vigorously, the nutrients are transported to the reproductive growth less, and the growth stops prematurely after the formation of the melon strips; when the melon strips expand, the water is not sufficient, and the nitrogen fertilizer is applied. Potassium fertilizer; under high temperature and dry conditions, the water and fertilizer are seriously insufficient, the spraying times are many, the plants are prematurely aging, and the zigzag is formed.

Three blame - fine waist melon Linyi fertilizer net copyright
Linyi Fertilizer Network Copyright
The performance of the melon strip is uneven, the central part of the fruit shrinks and becomes thinner, the melon and the melon end are thicker, and the thinned part is easy to break. Causes of formation: imbalance of nutrient supply, continuous high temperature drying; or lack of supply of boron before flowering and melon or boron to the melon transport is inhibited.

Four stranges - abortion melon (chemical melon) Linyi fertilizer network copyright
Linyi Fertilizer Network Copyright
It is characterized by yellowing, wilting, and even symptoms of dryness and wilting when the immature is in the early stage of expansion or when the fruit grows to a certain stage. Reasons for the formation: the flower is high and the rate of sitting is high, and the varieties that can sit on the melon can easily turn the melon, while the fruit of the melon is also easy to turn the melon.

Five strange - big belly pointed melon Linyi fertilizer net copyright
Linyi Fertilizer Network Copyright
The performance showed a significant change in the thickness of the melons. The central part of the fruit was thick and thick, and the tip of the melon was thick and the tip of the melon was thin. Causes of formation: female pollination is poor, part of the seeds form part of the nutrients and enlarge, and some of the nutrients that do not form seeds are less and do not expand; if the nutrient supply is insufficient or the watering is too late, it is prone to appear big belly .

Six blame - double body melon Linyi fertilizer network copyright
Linyi Fertilizer Network Copyright
The double-body melon sees two melons growing together when they are flowering. Causes of formation: caused by abnormal factors in flower bud differentiation, especially when high temperature, excessive application of nitrogen and potassium fertilizer, drying and other conditions are combined, it is easy to occur double-body melon, and after the absorption of boron is restricted, the incidence of malformed melon is also Greatly improve.

Seven strange - bitter melon Linyi fertilizer net copyright
Linyi Fertilizer Network Copyright
The melon has a bitter taste when eaten. Reason for formation: mainly determined by the characteristics of the variety. However, phosphorus and potassium fertilizers are insufficient. When the nitrogen fertilizer is too much, it will also cause bitter melon; the old plants are generally easy to bear bitter melon; when the room temperature is high, the nutrient consumption is high, and when it is dry, it is easy to cause bitter melon.

Prevention and control measures Linyi Fertilizer Network Copyright

To do early check and pick up Linyi Fertilizer Network Copyright
Linyi Fertilizer Network Copyright
It is necessary to check early and before the flowering of the female flower, and then remove it as soon as possible after the discovery, so as not to affect the normal growth of the upper part of the fruit. Linyi Fertilizer Network Copyright

Adjusting the temperature and humidity and light fertilizer Copyright Linyi
Linyi Fertilizer Network Copyright
Strictly follow the four-stage temperature-changing measures for cucumber growth and development, control temperature and humidity, strive to meet the temperature and humidity requirements of cucumber growth and development, and prevent premature aging; when the weather is insufficient, the artificial light-filling measures should be taken; When vines and vines are vines, it is necessary to prevent the stalks from being pulled and smashed; remove the old leaves and diseased leaves without growth function to ensure that the plants grow robustly.

Formulated fertilization measures Linyi Fertilizer Network Copyright
Linyi Fertilizer Network Copyright
From the application of the base fertilizer, it is mainly based on organic fertilizer, applying 15,000 kg of high-quality farmyard manure per mu, 300 kg of oil residue, and applying fertilizer with a ratio of 5:2:6 of NPK, the total amount of chemical fertilizer per It is advisable to apply about 120 kilograms per mu, and apply boron fertilizer in the right amount during the fruit setting period.

Pest Control Linyi Fertilizer Network Copyright
Linyi Fertilizer Network Copyright
Apply symptomatic symptoms after the occurrence of pests and diseases. The concentration of spraying should be appropriate, the number of times should not be too much. The foliar fertilizer should be sprayed once on the second day after spraying. The dosage is 0.2% potassium dihydrogen phosphate + 0.2% urea + 0.1% ternary compound fertilizer. +0.2% white sugar + vinegar to improve the plant's resistance to stress and prevent premature aging of plants.
