At present, the vast majority of wheat fields are seedlings, seedlings, and seedlings, and their growth is normal. However, there are also some problems that cannot be ignored: First, the number of individual sowing is still large and there are more basic seedlings. Second, in some places, peasants are eager to go out to work, robbing and planting sowing dates are too early. Third, a small number of wheat fields have poor quality of soil preparation, poor seeding, low seedling emergence, and lack of seedlings. Fourth, some wheat seedlings that were seeded in wheat fields in the evening were still single seedlings and could not form strong seedlings, which was not conducive to safe wintering. November wheat is in the stage of childbirth and is an important stage for the formation of strong seedlings. According to the current characteristics of wheat seedlings, it is necessary to scientifically manage fertilizer and water, strengthen field classification management, control wang and promote weak progress, promote seedlings early-onset, cultivate strong seedlings, ensure that the seedlings thrive in winter, establish a reasonable group structure, and build a high-yield shelf.
First, check seedlings to replant, dilute deficiencies wheat seedlings should be promptly check seedlings reseeding. First, we must do a good job in the investigation of the seedlings and master the dynamics of the seedlings, especially the wheat fields where the quality of the soil preparation is poor and the planting base is poor. We must carry out the seedling inspection work as soon as possible to understand the emergence of seedlings and manage seedlings. Second, we must do a good job of replanting and replanting the same species in a timely manner for ridge sections with 15 cm or more of ridges. Third, we must transplant the seedlings on the spot in wheat fields that are still short of seedlings. Where there are more basic seedlings, poor seeding quality, and seedlings in the wheat fields, they should be transplanted as soon as possible. When transplanting, wheat seedlings should be soiled and the roots should be compacted to ensure survival.
Second, timely cultivator cope with wheat in winter before a common cultivator, in order to break the consolidation, warming and protecting the earth, eliminate field weeds, and promote the development of roots and pods. Especially for wheat fields that have been flooded with headwaters, it is necessary to carry out early demarcation. For high-yield wheat fields before wintering, if the number of mu stems exceeds 1.5 times the number of planned panicles, a deep cultivator should be carried out in a timely manner to prevent the group from becoming too large in the later period.
Third, the fertilizer and water management without the application of base fertilizer or base fertilizer is insufficient, small groups, wheat seedlings grow thin wheat fields, should be in the pre-winter cropping period per acre topdressing urea 8 to 10 kg, watering after fertilization. For dryland wheat fields, cover with straw or soil to keep warm. The winter wheat field with sufficient base fertilizer, suitable population, and normal growth does not need to be top-dressed before winter.
Fourth, winter irrigation with winter irrigation can not only stabilize the temperature, promote the development of wheat roots, ensure the safe winter wheat, but also reduce the eggs of pathogens. At the same time, it can also prevent spring drought, creating favorable conditions for the management of spring wheat. Any wheat field where the soil is empty and lacks must be filled with winter irrigation.
V. Control and Prosperity Weak Weaknesses continued to be affected by the “greenhouse effect,†and meteorologists predict that the average winter temperature in China this year will continue to be on the high side. However, due to the influence of the “La Niña†phenomenon in the Pacific, it is expected that more frequent and intense cooling will occur in some regions this winter. Therefore, it is necessary to control the promotion of weak antifreeze and ensure the safe winter wheat. First, we must promote the early development of weak seedlings, speed up the transformation of the seedlings, and nurturing strong seedlings to achieve safe winter. The second is to control the length of the wheat seedlings as soon as possible. For wheat fields that are sown early and have a long growing trend, measures such as repression, deep-middle-cultivation, or chemical control should be taken in time to restrain the growth of wheat seedlings and control their growth. In order to control the fertilizer and water in the pseudo-prosperous Miao wheat field with large seeding volume, the weak seedlings shall be removed and the soil shall be kept dense. Third, before the onset of strong cooling weather, the wheat fields should be properly watered and protected against freezing. Fourth, it is necessary to formulate a plan to prevent freezing damage in wheat fields as soon as possible so that they can know what to do and deal with them scientifically.
VI. Preventing livestock from indulging green grass can reduce the photosynthesis area of ​​leaves and seriously affect the production and accumulation of nutrients in wheat seedlings. In addition, livestock bruises can also damage wheat seedlings, so that the ability of wheat seedlings to resist freezing and cold is greatly reduced. After the wheat seedling is damaged, although it can be re-emerged in the spring of the following year, the time for the initiation of tillering and young panicle differentiation is late, which will reduce the number of ears per mu and the number of grains per ear. At the same time, the stalks of the wheat seedlings are weak and prone to lodging, resulting in a significant reduction in the number of thousand grains and a serious reduction in production.
The medical protective shoe cover includes a coat, an inner bladder, a strap, a velcro surface, a non-slip bottom, and a velcro female surface. There is a sock-shaped inner liner that can be removed, and the anti-slip bottom is preferably provided with an anti-slip corrugated beef tendon bottom on the bottom surface; one side of the end of the strap is provided with a hook-and-loop fastener surface, and the other side is provided with a hook-and-loop fastener surface matching the hook and loop surface; the jacket Waterproof material is preferred, and elastic fabric is preferred for the inner liner; the jacket of the utility model is made of waterproof plastic material, and the anti-slip bottom surface adopts beef tendon bottom, which is strong and durable; The utility model can be reused after cleaning and disinfection, and can be used continuously after the inner tank is cleaned and disinfected; the arrangement of the straps enables the utility model to have the protection performance exceeding that of high-top shoe covers, but it is as convenient to wear as low-top shoe covers. Scope of application: used by medical personnel in medical institutions to prevent contact with potentially infectious patients' blood and body fluids, and play a barrier and protection role Instructions: Before use, unfold the isolation shoe cover, put on the shoe cover, put the socks and trousers into the isolation shoe cover, and fix it with straps. Through the actual operation of many people, it has been verified that Dongbei disposable non-woven isolation shoe covers are wear-resistant, waterproof, breathable, good isolation, and high-tube shoe covers do not slide down in one-time use.
