Zinc deficiency in wheat is a physiological disease caused by lack of zinc in the soil, which often leads to a decline in the grain weight of wheat, which generally affects about 10% of wheat yield. When wheat lacks zinc during the growth period, the internodes are shortened, the leaves are clustered, the leaf margins are wrinkled, and the veins are whitish-white, showing yellow, white, and green three-colored stripes, and the white seedlings and yellowing seedlings appear. Severe dead seedlings appeared in severe cases, and the earing was delayed and the spikes were small. In recent years, the disease has continued to expand and there has been a trend of spread, which should attract the attention of various parties. A cause of the high incidence of zinc deficiency in wheat in recent years: (a) The zinc content in the soil has decreased. The high yield of crops in successive years and the decrease of zinc content in soil are the main factors leading to the high incidence of zinc deficiency in wheat. (2) Excessive application of chemical fertilizers for nitrogen and phosphorus. As people's pursuit of crop yields is getting higher and higher, the use of chemical fertilizers is increasing, especially the use of nitrogen and phosphorus. The first is to increase the concentration of soil solution and increase the difficulty of absorbing and aspirating wheat. It is the antagonism of absorption of zinc fertilizer and phosphate fertilizer. In the soil with high effective phosphorus content, zinc deficiency is often induced. Reasonable soil phosphorus, zinc ratio of 25:1, the greater the ratio of phosphorus and zinc, the lower the chance of wheat absorption of zinc; Third, high soil nitrogen content, but also inhibit the effectiveness of soil zinc. (c) Increased soil organic matter, increased activity of soil microbes, and complexation of available zinc in the soil, thereby reducing the effectiveness of soil zinc, indicating temporary zinc deficiency. This symptom usually disappears after a period of time after the growth and development of wheat. (d) The increase in soil multiple cropping index has taken away a large amount of soil that would have been effectively lacking in soil. Second, prevention and control measures (a) actively use formula fertilizer. The Wooli brand wheat formula fertilizer containing trace elements "Zinc" necessary for wheat growth and other nutrients will not cause physiological diseases. It will not only save labor and time, but also save time, price, and economic benefits. (b) promote balanced fertilization. It is based on balanced fertilization. First, do not apply a single long-term fertilizer; Second, based on fertility and target yield reasonable fertilization; Third, according to the characteristics of wheat during growth to determine a reasonable proportion and methods of sub-fertilization, to eliminate a shelling fertilization habits. (C) application of basal. Each hectare uses 1 to 2 kilograms of zinc sulfate heptahydrate, and the mixed fertilizer or sandy soil is applied to the soil during site preparation. Generally, it is applied once every 3 to 5 years. (d) Soaking. Place the selected wheat seeds in a 0.05% zinc sulfate heptahydrate solution, soak for 12 to 24 hours, remove and dry them. (five) spraying foliar fertilizer. Can be used 0.30% ~ 0.40% of the zinc sulfate heptahydrate solution sprayed foliar, continuous spray 2 ~ 3 times, separated by time 5 ~ 7 days, preferably mixed with amino acid and humic acid foliar fertilizer spraying. Third, pay attention to zinc fertilizer as a base fertilizer when the amount of application of not more than 2 kg per mu, spray concentration should not exceed four thousandths of a thousandth, otherwise it will cause poisoning, but adverse to crop growth. Zinc fertilizer has poor mobility in soil and is easily fixed by soil. Therefore, be sure to spread evenly and spray evenly on the leaves. It is best to spray on the front and back sides of the crop leaves, otherwise the effect is not good. Do not mix zinc fertilizer with alkaline fertilizers or alkaline pesticides, otherwise it will reduce fertilizer efficiency. Zinc fertilizer has a post-effect. It does not need to be used as a basal fertilizer for consecutive years. Generally, the effect of application is good every other year. At present, there are many fake zinc fertilizers on the market. Most of them are replaced with magnesium fertilizers. Please pay attention to authenticity.

For the treatment of diseases of the Digestive System:

Many symptoms can signal problems with the GI tract, including: abdominal pain, blood in the stool, bloating, constipation, diarrhea, heartburn, incontinence, nausea and vomiting and difficulty swallowing, according to the NIH.


Among the most widely known diseases of the digestive system is colon cancer. According to the Centers for Disease Control (CDC), 51,783 Americans died from colon cancer in 2011 (the most recent year for available data). Excluding skin cancers, colon and rectal cancer, or colorectal cancer, is the third most common cancer diagnosed in both men and women in the United States, according to the American Cancer Society.


Polyp growth and irregular cells, which may or may not be cancerous, are the most common development paths for colorectal cancers (also referred to as CRC), and can be detected during a routine colonoscopy, according to Dr. John Marks, a gastroenterologist affiliated with the Main Line Health health care system.


[The best news is that, if caught early enough, they can also be removed during the colonoscopy - eliminating the possibility that they grow further and become cancer," Marks said.


For those patients whose cancer has already spread, there are various minimally invasive surgical options that have extremely good prognoses. It is recommended that asymptomatic patients without a family history begin getting tested regularly between the ages 45 and 50, according to Marks. [Symptoms which may suggest that you need a colonoscopy at an earlier age include rectal bleeding and stool/bowel habit changes which last for more than a few days."


While CRC gets a great deal of attention, many diseases and conditions of the digestive system - including irritable bowel syndrome, diverticulitis, GERD (acid reflux) and Crohn`s disease - can be chronic and are difficult to diagnose and treat, according to Dr. Larry Good, a gastroenterologist affiliated with South Nassau Communities Hospital. [With many of these diseases, blood work and colonoscopies all looks normal, so there is an absence of red flags."


Many of the diseases of the digestive system are tied to the foods we eat, and a number of sufferers can reduce their symptoms by restricting their diets, Good said. [Of course no one wants to hear that they can`t eat certain foods, but many times, eliminating acidic things from the diet, such as tomatoes, onions, and red wine, can have an impact," Good said.


There are a number of tests to detect digestive tract ailments. A colonoscopy is the examination of the inside of the colon using a long, flexible, fiber-optic viewing instrument called a colonoscope, according the American Gastroenterological Association. Other testing procedures include upper GI endoscopy, capsule endoscopy, endoscopic retrograde cholangiopancreatography and endoscopic ultrasound.
