(1) Protection of seedlings: spraying with new high fat film on the surface of wheat seedlings to prevent the infection of pathogens, improve the ability of natural disasters, increase photosynthesis, and protect the growth of wheat seedlings. Combined with surface spray (600-800 times liquid) sprayed on the soil surface, it can protect the water evaporation, evaporation, sun protection drought, insulation and antifreeze, prevent soil compaction, isolate pests and sources and suffocate destroy. (2) Fill irrigation with water to promote seedlings and feet. The suitable soil moisture for wheat emergence is 70%-80% of field water capacity. For those wheat fields that have not been watered or irrigated before seeding, and the surface moisture is poor, it is difficult to assure the emergence of wheat fields as soon as possible. The new high-fat membrane mist agent should be sprayed to strengthen the conservation step to promote seed germination and seedling growth to ensure the basic seedlings. the amount. (3) Check seedlings to replant and promote seedlings. During the emergence of wheat, check the seedlings in a timely manner. If the seeds of the same variety are immersed in the new high-fat membrane, reseeding the seedlings as soon as possible; or in the 3-4 leaf stage of wheat, transfer and thinning. When transplanting, the depth of soil covering should be controlled with “no pressure on the top and no whiteness on the bottomâ€. After filling the seedlings, watering is done practically, and appropriate fertilizers are supplemented so as to promote early-stage seedlings. (D) timely winter irrigation, seedling maintenance winter. For the wheat fields with straw returning, rotary tilling, soil vacancy and lack of crops, winter irrigation must be carried out to stabilize the soil, promote the development of wheat packing and bark, and keep the seedlings safe for winter. Winter irrigation time is generally carried out when the average daily temperature is around 3°C. It is completed before freezing and the water volume is generally 40 cubic meters per acre. Flood irrigation is prohibited, and loose soil is removed after pouring. Nootropics,Alpha-GPC,Choline , CDP-Choline , Coluracetam,Noopept PYSON Co. ,Ltd. , https://www.pysonbio.com
