1. Selection of varieties: In the vicinity of Longdong, wheat varieties with strong stress resistance should be selected. Such as: Jingdong No. 8, the winter of this species is stronger. 2, timely planting and cultivating strong seedlings: As the saying goes, Bai Lu early cold exposed late seeding wheat is the time. In recent years, the temperatures in late autumn in eastern Fujian are relatively high, and most of the farmers are cold and wheaty. According to the early and late sowing, strict control of sowing. Timely sowing, equinox - cold dew, species with 10-15kg per acre. Tens of thousands of pounds of seedlings, that is, l pounds of wheat can be planted after the broadcast of 10 000 wheat seedlings. If l0kg wheat seed is planted per acre, 200,000 mu seedlings will be planted. The lOcm see side has 3 basic seedlings, the single plant nutrient area is sufficient, the winter wolfberry is more, there is sufficient nutrient in the karmic section, easy to form strong seedlings. Strong seedlings can make at least 2 spikes. Calculated on the basis of 400,000 grains per acre, the number of grains per panicle is 35, and the grain weight is 40g, so the wheat yield per mu can reach 560kg. Seeding early seedlings is prone to leggy, and it is necessary to control its growth in time to avoid jointing before winter wheat to reduce the occurrence of frost damage. The late sowing of wheat, based on the application of organic fertilizer, appropriate application of a small amount of fertilizer, application of 7.5kg per acre diammonium phosphate, can promote the development of wheat roots, enhance the delivery force, is conducive to the storage of more nutrients at the tiller, enhanced Cold resistance. 3, to strengthen the fertilizer and water management: According to the growth of wheat seedlings to strengthen management, they will turn weak seedlings into strong seedlings. Weak seedlings have poor root absorption capacity and slow growth. Therefore, extra-root topdressing for weak seedlings can be sprayed with Huafu's plant growth promoting agent, potassium dihydrogen phosphate. Its purpose is to prevent the freezing of the tiller section of the wheat seedlings, which is conducive to the formation of high spawns. The purpose of winter wheat rolling is to compact the frozen cracks in the wheat field, prevent the roots of wheat from freezing, and reduce the occurrence of dead seedlings. 6, barred wheat grazing: wheat grazing in winter wheat can greatly reduce production, the reason is: after grazing, plant green area is greatly reduced, nutrient production and accumulation decreased significantly, ear differentiation began late, delayed maturity, ear, ear, Small grain and light weight. Grazing can also cause mechanical damage to wheat seedlings and accelerate water transpiration. At the same time, it reduces the coverage of tillering knots and aggravates freezing injury. 7. How to remedy the missed wheat season: (1) Seventy-seven Act: From the “winter solstice†day, the winter wheat Seeds are soaked in well water, taken out the next morning, dried in the 0-5 environment and processed once every 9 days. Totally processed 7 times. (2) Stuffy wheat method: Stir the germinating winter wheat seeds in a pot and treat it at a low temperature of 0-5 degrees for 40-50 days. After these two methods have been used to treat winter wheat seeds, they can be sown in the spring like spring wheat, and they can also normally bloom and grow.
