Editor's note: At the moment, wheat is in a critical period of growth. In the southwestern region, winter wheat has entered the jointing and booting stage, and wheat in the middle and lower reaches of the Yangtze River, Huanghuai and other places have gradually returned. This is an important period for strengthening field management. In view of the characteristics of this year's wheat seedlings, the technical points of the field management in spring are: Highlight the word “earlyâ€, base on the word “defense,†and manage the land due to seedlings. Freezing damage to wheat as early as possible to promote early management Wheat freeze injury is one of the major disasters that affect wheat production, and it is also an inadaptability reaction of wheat itself to the external low-temperature environment. It occurs frequently, has a large area and causes serious damage. At present, the wheat in the irrigated area has entered the jointing stage, and the dry land gradually enters the returning green period. Affected by the recent low-temperature weather, wheat in some areas suffers from freezing damage. If it is not controlled in time, the yield and quality will be affected. Zhang Rui, a professor at the Agriculture College of Northwest Agriculture and Forestry University, reminded him to constantly pay attention to the changes in the weather and manage it according to local conditions. Zhang Rui pointed out that the current management of wheat is very crucial to avoid the freezing of wheat caused by the late spring. One is to moderately inhibit the growth of excessively prosperous wheat fields. The main measure is the spraying of chlormeson chloride during the start of wheat growth. The second is that irrigation can prevent freezing damage. The third is topdressing nitrogen fertilizer and foliar spraying after frost damage. Once the cold injury occurs, Wang Miao should be treated as weak seedlings and immediately apply fertilizer. In general, 7 to 10 kg of urea can be applied per acre. At the same time, spray foliar fertilizer. After the occurrence of freezing injury, spraying wheat plants with potassium dihydrogen phosphate and foliar fertilizers has a good effect on promoting the recovery of wheat. “In the wheat fields that had already been jointed before freezing, the main stem and the Oita were able to freeze, but they could no longer inhibit growth.†Zhang Rui emphasized that since the main stem and the growing point of Oita suffered freezing damage, the growth center has begun to shift to still survive. There is no chance of further growth. If restraining measures are taken, it will cause harm and adverse effects on the growth of small tillers, so it is important to promote the growth of small tillers. Watering early in droughty wheat fields When wheat was sown last year, the weather was relatively dry in most areas. In some areas, there was a long period of drought and lack of rain, and there was also a lack of irrigable conditions. This caused poor wheat moisture. Although there was little rainfall at a later stage, some farmers sow late and were affected by temperature. At this stage, the return of wheat to the young seedlings is poor. "If the spring irrigation is not appropriate, the development of drought will have a certain impact on the stable production and high yield of summer grain," said Zhang Rui. Taking Shaanxi Province as an example, since March, the average rainfall has fallen by 30% from the average annual value. According to the prediction of the Shaanxi Meteorological Department, the first flooding rain will occur in the latter part of mid-April, and it is easy to form spring drought disasters. The growth of crops and the production of spring plowing have caused adverse effects, and the drought situation is not optimistic. In response to the drought, Zhang Rui reminded the growers that they must seize the wheat to return to the green period, water and protect the seedlings, and resist drought promptly. Zhang Rui pointed out that it is necessary to supplement irrigation in time after soil thawing, drought protection seedlings, watering after the timely scratching, breaking the consolidation, and further improve soil moisture. If the wheat field with poor watering conditions should be repressed in the early spring soil thawing, reduce water evaporation and promote root growth. Focus on scratching and repression The management measures for spring wheat fields should be appropriately moved forward, and the weak weak seedlings should be strengthened. At the same time, it is necessary to highlight the classification management, construct a reasonable group structure of various types of wheat fields, and establish a high-yield shelf. Zhang Rui said that it is important to focus on repression, security, warming and promoting early development. The field management in the three wheat fields should be based on promotion. In particular, "a needle" wheat field, through "early strokes, early fertilizer," and other measures to promote the transformation and upgrading of seedlings. The focus of field management in spring wheat in the second category is to promote spring delivery, consolidate tillering before winter, and increase the percentage of tillers in winter and spring tiller. In the management measures of a kind of wheat field, it is necessary to highlight the backward shift of nitrogen fertilizer, and the spring wheat management of the prosperous wheat field should be based on the control measures. Prevent pests and diseases as soon as possible With the gradual increase in temperature, wheat pests and diseases begin to occur, and great attention should be paid to early prevention and treatment. Focus on prevention and control of wheat full-blown disease, wheat spiders, and midgeworms; after wheat heading, it is necessary to prevent and control wheat aphids and powdery mildew in a timely manner. Full wheat rot disease: use 12.5% ​​wolfberry fruit 30 to 40 g/mu or 15% triadimefon 200 g, and weigh 200 kg of water along the base of the stalk. Wheat spiders: Spray 40% dimethoate 1000 times or 1.8% abamectin 3000 times per acre. Wheat midge: Use 5% chlorpyrifos granules 600-900 grams per acre or 2% methyl isofluosone powder 2 kg, and spread fine soil 25 kg evenly on the surface. Immediately after application, water was applied and adults were sprayed with 2.5% deltamethrin EC 4000x. Wheat Powdery Mildew: Use 20% Tetrafen 50 ml per acre to spray 30 kg of water. Wheat aphids: Spray with 10% imidacloprid 1000 times or 2.5% deltamethrin 3000 times per acre. Although corn is sweet, it is important to note that it is a medium glycemic index food, which means that the sugar content is not very high, so why does it taste sweet? This is a question for many people. In fact, corn tastes sweet because it contains soluble new sugar substances, but in general, its carbohydrate content is actually not high, so it is still suitable for people with high blood sugar to use as a staple food to help control blood sugar.

Corn can control blood sugar, but you have to be careful how you eat it
But the doctor is to remind everyone that although corn can help control blood sugar, but it is recommended that we corn food life or need to eat the right only important, if a single consumption of corn, as a medium glycemic level of food, corn will still lead us to elevated blood sugar please, in addition will lead to indigestion, body flatulence, etc., resulting in our body's nutrient supply is insufficient, so life we for eating duo to pay attention to.
