1, the first year is mainly to tree transformation. Focus on catching heads, digging and retracting. Falling down refers to the selection of a suitable site for the tall and empty trees to remove the tree head, lower the tree height, and solve the lower light, which lays the foundation for the cultivation of the neonatal twigs of Nei. In general, plants that are more than 4.5 meters high in the center should be left in the place of 4 meters in height to leave a happy and strong branch to head over and be happy. They should peel off the "top cover" to facilitate the growth of the lower branches and restore growth. Thinning refers to the elimination of upright large sticks on the back. This promotes balanced development of the branches and is full and full. In addition, drooping branches, diseased and diseased branches, dead branches, slender branches and cross branches should be removed to improve light, improve photosynthetic efficiency, and promote leaf growth and flower bud differentiation. The retraction is all moderately cut for all kinds of branches, the strong branch stays with the Zhongyong branch, and the weak branch group selects the strong branch, so that the growth potential can be adjusted, the nutrient transportation distance can be shortened, the nutrition can be concentrated, the branches can be cultivated, and the result can be enhanced. .
2. In the second year, pruning mastered the principle of “one sparse, two stays, three promotionsâ€. Due to heavier pruning in the previous year, the entire branches were strongly stimulated, so more new branches could be drawn. For new branches that were peripherally pumped in the same year, all but the main branches were left to be removed to increase the light in the inner chamber; the new branches in the current year should be properly preserved to form a branch outside the crown and a new branch in the crown should be kept. The whole tree grows in balance. And make nutrients concentrated in the crown, prompting budding germination to produce new branches, increase the growth of new shoots, so that the fruit tree sub-subsidiary shoots increased significantly, and some become growing branches. As a result, the old tree grows weaker, stronger, more balanced and balanced.
3. In the third year, the neonatal twigs were cultured. Start training the new shoots that were picked up in the previous year and leave more for early cultivation. The large, medium and small branches of pears are all easily uniaxially stretched, so they should be made as many branches as possible to form a fan-shaped unfolding group, increasing the area of ​​results. Afterwards, the branches and branches are continually updated and rejuvenated, and the robust branch groups are cultivated to achieve the goal of high quality and high yield for consecutive years.
In addition, attention should also be paid to soil improvement, prevention of soil erosion, application of base fertilizers and topdressing fertilizers, and comprehensive control of pests and diseases to achieve increased production, stable production, and high quality of old trees.
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.
