The cause of "Cucumber rotten bibcock" in Farmers' planting Cucumber and its Control Plan

The total planting area of cucumber in the greenhouse is large, and the production capacity is high, but there are also many kinds of diseases. In the cold winter, the problem of towel gourd rotten faucet produces more, which seriously harms all the normal growth and development of towel gourd. And there are many reasons for towel gourd rotten faucet, resulting in farmers can not identify, prevention is difficult coefficient. What is the direct cause of towel gourd rotten faucet? How to match the prevention plan in order to completely eliminate this problem?

Explanation of symptoms:

Calcium deficiency is the root cause.

There are two key reasons for towel gourd rotten faucet: one is the typical symptom of calcium deficiency, which occurs in the early stage of blooming melon. When the main stem grows to 0.5-2 meters, it is mainly manifested as the withering of the stem tip of the heart leaf, and the foundation of the leaf stem is asymptomatic. The arch shed is very extensive when it is produced, and it usually breaks out on a large scale in the whole shed. The second is caused by infectious diseases, the key are vine blight, bacterial infection blight, scab and so on. When this kind of disease occurs, the leaves and stems usually have typical symptoms of the disease, such as vertical cracking of stem and V-shaped spots on leaves. The condition of the rotten faucet caused by the disease is usually produced independently in the early stage, dots are everywhere, and slowly expands in the middle and later stage. Farmers can distinguish the causes of the disease and take medicine for prevention according to the production of rotten faucets in the arch shed.

Speaking of, many diseases will also lead to rotten faucets, why is it said that calcium deficiency is the root cause? Here we need to start with the main manifestations of calcium deficiency. Typical symptoms of calcium deficiency, such as umbilical rot, all occur when calcium deficiency is already very serious, such as the late symptoms of human lung cancer are more significant, although the early stage has not caused significant symptoms, but the damage caused by deficiency still exists. Not long ago, people mentioned that the dark spots on the reverse side of leaves on cloudy days are a major manifestation of calcium deficiency, but it does little harm and can still be repaired. Generally speaking, the new buds around the bud eye, like newborn babies, have strong disease resistance, low infection probability of pathogens and less disease. However, when calcium deficiency in the main stem is not serious and does not mainly show the typical symptoms of calcium deficiency, calcium deficiency will still endanger the normal development of the main stem, resulting in low cell mitotic activity of calcium-deficient parts such as heart leaves, fruit tips and tooth roots. the effects of cytoplasm and cell wall are affected, and the ability to adapt to extreme standards such as high temperature, ultra-low temperature and dark light is poor, and the ability of stress and disease resistance is reduced. It is very easy to be infected by pathogenic bacteria. It can be said that the new buds around the bud eyes are often infected by pathogens, which may be due to calcium deficiency in the main stem and poor disease resistance of new buds.

The plan is highly recommended:

Supplement calcium and zinc to prevent diseases

1. Calcium fertilizer is difficult to supplement, so it is important to choose the right way.

It is said that the rotten faucet is lack of calcium, but I sprayed calcium fertilizer several times, how to fail? It is the concern of many farmers. If you want to master this, you must first master the characteristics of calcium fertilizer. Calcium is the laziest of all trace elements, and it is difficult to digest and absorb. It is very easy to be fixed before and after digestion and absorption, and the activity is poor.

To apply calcium fertilizer, farmers choose more ionic calcium fertilizer, such as calcium nitrate and so on. After the application of ionic calcium fertilizer, it can be fixed by * loam colloid solution in about 2 hours, which can not be transported like other elements, and it is difficult to digest and absorb the rhizome. Solution: select high active calcium fertilizer and strongly recommend floating calcium in Taurus, which is not easy to be fixed, high activity and stronger actual effect.

When the leaves are sprayed with calcium fertilizer, it is mainly the mature leaves that digest and absorb the calcium fertilizer. One of the characteristics of calcium fertilizer is its poor activity, and the calcium fertilizer entering into the leaf is limited in the leaf and can not be migrated out and used again, and the calcium fertilizer digested and absorbed by the leaf can not reach the bud eye where there is a real lack of calcium. As a result, the actual effect of calcium and zinc supplement in leaves is weak. Solution: change the habit of the sprayer, spray new buds, bud eyes, fruits and other parts of the sprayer, and add modifiers such as an Rongle, which can enhance the activity of calcium fertilizer in the main stem, so that the calcium fertilizer in yellow leaves can be shipped out and used again.

two。 Disease prevention

After the production of rotten faucets, it is very easy to be infected by pathogens, so it is necessary to improve disease prevention. Farmers should take medicine according to the disease and symptomatic treatment, so that the actual effect is more guaranteed. If you can't tell the difference, here we strongly recommend a universal secret recipe, which can prevent vine blight, bacterial infection, scab and so on.

Highly recommended secret recipes: Fushuai 1500 times, thiazole zinc 400 times, Ishiyuan Taurus floating calcium 1000 times, alginic acid 700times.

Fushuaide has a broad spectrum of bacteria, and has a good control effect on blight, vine blight, scab, gray mold and so on. Zinc thiazole has a special animation effect on bacterial infection diseases, and can also prevent a variety of Candida diseases. Broad-spectrum high efficiency, can prevent most of the pathogens infecting bud eyes. Calcium fertilizer and alginic acid can improve the drought resistance of crops, promote the growth and development of heart leaves, reduce drug damage, help pesticide fungicides, and achieve stronger control effect.
