Winter wheat from the emergence to winter, fertility characteristics are long-rooted, long-leaved, long-term tillering, complete vernalization stage, that is, "three-year-long completion", the growth center is childbirth. The central task of field management is to build on the basis of conservation of seedlings, promote root growth, make weak seedlings grow stronger, and strong seedlings grow steadily to ensure that the wheat seedlings safely pass through the winter, laying a good foundation for the panicles and spikes in the coming year. 1. Seedling replanting due to leakage of seed, lack of earthworms, underground pests and other reasons, resulting in lack of seedlings broken ridge, timely check seedling reseeding, will replant the wheat seed soaked in cold water for 24 hours after drying to ensure seedlings Whole seedlings evenly. II. Elimination of seedling pests and diseases Common seedling pests include earthworms, planthoppers, underground pests, leaf rust, etc. Once they are detected and controlled in time. Third, overwhelming needle wheat into the three-leaf stage, the seed nutrient depletion in the endosperm, seedlings rely on their own photosynthesis, the production of nutrients for growth and development needs, which is the key period of promoting root augmentation. Overwhelming the needle is a powerful measure, that is, repressing it at the three-leaf stage to control the main stem, promote the delivery of tinea, control the ground and promote the role of the root system. 4. In the event of rain during the tillering period of the commissariat, the wheat sloping soil should be promptly scratched, which will help to eliminate the compaction and promote root growth. For Wang Miao, deep scratch (more than 7 cm), can play a role in root control. Saline-alkali wheat should be washed after rain and prevent back-salt from harming wheat seedlings. 5, pouring a good winter water, fertilizer fertilizer should be timely irrigation in due course, generally at an average temperature of 7 °C ~ 8 °C when the beginning of the time to about 5 °C, a time when the frozen night, the amount of winter water should not be too large, can be drenched the same day Infiltration is appropriate, avoid flood irrigation. For the wheat seedlings with insufficient or early seeding in the basic seedlings or unfertilized seedlings, combined with winter fertigation, 5 kg to 10 kg of urea is chased every 667 square meters, prompting the wheat to return to green as early as possible, consolidate the tillering before winter, and increase the number of tillers. Rate, so that winter fertilizer spring. Sixth, winter urine to prevent damage to the wheat seedlings after the winter to return to green can be poured before urine, with the plot with the pouring, generally urine 500 kg per 667 square meters, saline or alkali wheat or wheat fields should not be poured when the urine, pouring urine significant effect, About 15 kg of fresh urine can increase production by 1 kg. Seventh, the cover is said to be good by the farmer: "Mai eats lunar soil." The cover is protected against cold and seedlings. Technical points: After the wheat enters the overwintering period, the wheat seedlings will turn yellow after it is too early; when the leaves are too late, the leaves will be frozen and the operation will be difficult, which will not achieve the desired effect. After the winter irrigation, on the basis of the recalcitrant soil, bamboo shoots were used to cover the seedlings on the bamboo shoots in the Daxing Zhongrong, and the cover soil was about 2 cm. This technical measure can stabilize the temperature, reduce the evaporation of soil moisture, ensure that the wheat is green over winter, reduce the cracking of the ground, and make up for cracks. 8. After the repression cover is crushed, it is necessary to roll the wheat once or twice before returning to green, and crush and pulverize the waste to make the soil fine and compact. This will help eliminate compaction, cracking, heat preservation, and soil sealing, and prevent soil leakage. This is an important measure for the management of winter wheat in water-deficient wheat fields, and is another important means for drought resistance and cold-resistant seedlings. 9. It is forbidden to pass through the green leaves preserved during the overwintering period of the grazing in the wheat fields. Photosynthesis can be carried out after returning to the green. It is the main source of nutrients needed for fresh growth. Winter grazing will cause a lot of damage to this part of the green area, weakening the ability to resist cold and reducing yield.
Snacks usually refer to the food eaten outside the time point of three meals a day. Under normal circumstances, in people's life, except that three meals a day are called dinner food, the rest are called snacks. Canned fruit is a healthy snack.
