How to do calcium deficiency in summer vegetables?
Most vegetable crops prefer calcium, which requires more calcium. The calcium absorbed by vegetables plays a variety of roles in the plant body, which can promote the development of its cell wall, reduce the extravasation of nutrients in the body, inhibit the infection of pathogens, improve the disease resistance of plants, and eliminate the harm of excessive organic acids in the body. Promote various metabolic processes in the body. Once the vegetables are deficient in calcium and the metabolism in the body is blocked, various calcium deficiency symptoms, such as tomato umbilical rot, will occur. The related problems and measures are as follows:
The general symptoms of calcium deficiency in vegetables: the new parts of the plant such as the top buds, root hair growth stagnation, atrophy and death, new leaves adhesion, the new leaves often open, the incompleteness; the top of the fruit is prone to depression, dark brown and necrosis.
Tomato, sweet pepper umbilical rot: In the early stage of the disease, the bud front of the young fruit (the end of the petal detached) is water-soaked, and the peel is intact. As the fruit expands, the affected part of the front of the fruit shrinks and dark browns, and the lesion is located. Often affected by secondary mold infection, showing a rotten top. There is no obvious tomato in the top of the sweet pepper, mainly brown and dead. Umbilical rot usually occurs when the fruit is near the size of the thumb, and the fruit of the inflated period generally does not occur.
Calcium deficiency is easy to occur: soil itself is deficient in calcium; soil salt content is high, inhibiting roots to absorb water and nutrients; soil drought, increasing soil solution concentration, reducing root water absorption, thereby inhibiting calcium absorption; excessive application of ammonium nitrogen It will inhibit calcium absorption, and the incidence of dry heart disease in Chinese cabbage will increase with the increase of nitrogen fertilizer application.
Corresponding control measures: To control the amount of fertilizer, it is not advisable to use too much fertilizer at one time, especially for chlorinated fertilizers such as ammonium chloride and potassium chloride; to irrigate in time to prevent soil drought; to spray calcium on the foliar surface, calcium chloride may be used. And calcium nitrate as a spray fertilizer, the concentration of 0.3% -0.5%. Generally, it is sprayed once every 7 days, and even sprayed 2 times - 3 times. Tomatoes should be sprayed with 2 leaves - 3 leaves above and below the flowering inflorescence; Chinese cabbage is sprayed with calcium at the beginning of the ball-forming period. In addition, the addition of auxin substances such as naphthalene acetic acid during calcium spraying can promote the absorption of calcium. The specific method is: calcium chloride 0.7%, plus naphthalene acetic acid 50ppm, sprayed after mixing; apply lime fertilizer, such as gypsum, Calcium phosphate, calcium magnesium phosphate fertilizer, etc., calcareous soil generally does not have to apply calcium fertilizer alone, usually calcium has been introduced when applying phosphate fertilizer.
There are two types of dietary fibre - soluble and insoluble - and sweet corn contains both.
According to the American Heart Association, dietary fibre as part of an overall healthy diet helps to lower blood cholesterol levels and may reduce the risk of heart disease. It is insoluble fibre that binds to cholesterol, preventing it from being absorbed into the bloodstream.
Insoluble fibre is responsible for promoting regularity and helping to prevent constipation by speeding up the passage of food and waste through the intestines and absorbing water to keep stools soft. Insoluble fibre has been shown to reduce the risk of haemorrhoids.
Fibre-containing foods such as sweet corn also help to provide a feeling of satiety and may therefore help to suppress appetite and aid weight management.
Dietary fibre has also been linked to a reduced risk of type 2 diabetes. A diet rich in fibre helps patients manage their disease.
Fibre is fermented by bacteria in the colon. Promising studies are underway to determine the health-promoting effects of fibre fermentation breakdown products, for example, short-chain fatty acids, which may help to maintain a healthy gut.
