Seed treatment method capable of increasing direct seeding emergence rate of loofah

The invention belongs to the technical field of loofah planting and particularly relates to a seed treatment method capable of increasing the direct seeding emergence rate of loofah. The method specifically comprises the steps as follows: (1) loofah seeds are immersed in a monopotassium phosphate aqueous solution to be soaked at the constant temperature and fished out, and the obtained loofah seeds are placed in a refrigerator to be frozen; (2) the frozen loofah seeds are immersed in a seed soaking agent to soaked at the constant temperature and fished out, and microwave drying is performed until the water content is 15%-17%. The seed soaking agent is prepared from raw materials as follows: borax, zinc sulfate, a griffonia seed extract, resveratrol, luteolin and water. Seeding can be performed after treatment without germination acceleration, the method is quick and convenient, quick germination and seedling emergence of loofah seeds can be effectively promoted, so that the emergence rate reaches 98.5% or above; besides, seedlings grow vigorously, root system growth and elongation capacity is high, the nutrient absorbing capacity of seedlings can be effectively promoted, the disease resistance and drought resistance are high, germs and viruses can be resisted effectively, and the seedling rate can be effectively increased to 96.5% or above.
