Due to the strong rainfall that occurred during the wheat planting period around the eleventh year of last year, the wheat farmer began to plant seeds after the winter monsoon and formed late wheat. In addition, the rainfall at that time delayed the growth of the wheat planted at normal time and also formed late wheat. More than half of the 1.1 million mu of wheat planted in the city last year was late wheat. Fertility characteristics of late wheat are different from that of common wheat. Therefore, early spring management techniques are not the same. Late wheat generally refers to wheat sown after cold dew. Its fertility characteristics are different from that of wheat sown in the proper period. The main manifestations are: the wintering seedlings are young; the tillering is small; the secondary roots are few; the stems in the ground are short. The root mass of late wheat is mainly in the green period. The main reasons for the production loss caused by late wheat production are: first, insufficient number of acres; second, lack of phosphate fertilizer, emergence of young and old seedlings; third, the practice of early sowing and early tube management in early spring management, early watering, multiple watering, multiple fertilization . Due to the excessive water in the returning green period, it often causes cold, soil and alkali return, which is unfavorable to the development of the root system, delaying the birth of wheat and causing the earing to be late. Therefore, the early spring management of late wheat is mainly focused on increasing the ground temperature, maintaining ventilation, and promoting the early emergence of seedlings to take measures. 1. Divide the soil. After watering or after rain, remove the water and preserve the soil moisture. This is the main management measure for saving water and drought in early spring wheat. 2. Top Ling topdressing fertilizer, especially phosphate fertilizer. Due to the low temperature in early spring, the soil's ability to supply phosphorus is weak. At the same time, the wheat root group is small, and the ability to absorb phosphorus is weak. Therefore, early wheat is sensitive to phosphorus in the early spring. If the phosphorus is insufficient, small old seedlings will be easily formed, which will lead to a reduction of wheat production. Generally more than 400 kilograms per night wheat yield, the total amount of NPK fertilizer application of 35 kg of urea per acre, 25 kg of ammonium phosphate, 15 kg of potassium sulfate is more appropriate. And 60% of the total nitrogen and all of the phosphate fertilizer, potassium fertilizer as a base fertilizer application. For the wheat field with insufficient fertilizer, it can be used in the early spring to make use of the trenching fertilization method to top fertilizer and to make up for the deficiency. 3. Delay the time of spring fertilization and watering. For wheat fields with adequate ladle and adequate winter irrigation before winter, the suitable watering time for late wheat can be grasped. The new root (latent taro) is exposed, the new root grows about 1.5 centimeters, and the panicle differentiates into the digozoic phase. The general time is 4 In the middle of the month, 40% of the total nitrogen fertilizer is applied in combination with watering. If the soil moisture content is not enough, according to the growing situation of wheat seedlings, appropriate early management. 4. Prevent fall and weeding. Due to the relatively large amount of late wheat sowing, the root groups are small in early spring. If the management is not good, they are easy to fall down. Therefore, we must pay attention to prevent lodging and weeding during the jointing period.
