Method for improving watermelon seed germination rate

Abstract

The invention discloses a method for improving the germination rate of watermelon seeds. The method comprises the following steps that 1, full and undamaged seeds are selected and naturally dried, ultraviolet sterilization is performed under the airtight condition of the temperature of 20-25 DEG C, and then a fast neutron source is used for irradiation; 2, temperature change treatment is conductedon watermelon seeds in the step 1, magnetization treatment is performed, the seeds are soaked in germination promoting liquid for 12-14 hours and then are air-dried under the room temperature condition, and then the seeds are put on a wooden screen for steaming; 3, the steamed seeds in the step 2 are treated under the low temperature condition and then are uniformly spread under the sun for natural drying, and seeds with improved germination rate are obtained. By adopting the method for improving the germination rate of watermelon seeds, the germination rate of seeds can be improved, and meanwhile the disease resistance capability of the seeds can be improved. The method is friendly to the environment and has higher use value and a good application prospect.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for improving the germination rate of watermelon seeds. Background technique [0002] Watermelon likes a warm and dry climate, and is not cold-resistant. The optimum temperature for growth and development is 24-30 degrees, the optimum temperature for root growth and development is 30-32 degrees, and the lowest temperature for root hairs is 14 degrees. Large temperature difference between day and night, watermelon is resistant to drought and humidity, when there are many rainy days, the humidity is too high, it is susceptible to disease, watermelon likes light, and the growth period of watermelon is long, so it needs a lot of nutrients. As the plant grows, the amount of fertilizer required for watermelon gradually increases , When the fruit grows vigorously, it reaches the maximum value. It has strong adaptability. The sandy soil with loose soil, deep soil l...

Problems solved by technology

[0003] In the prior art, the soaking method is often used to improve the germination rate of seeds. This method leads to low germination rate of seeds and serious infestation by pathogens. Chinese patent literature (publication number: CN104025837B) discloses a method for accelerating germination of watermelon seeds, including seed selection and seed soaking agent. Soaking seeds, soaking seeds in microwave nutrient solution, magnetizing in a magnetizing machine, storing seeds at variable temperature in a refrigerator, dressing seeds with rare earth, and finally accelerating germination, this method is not very effective in improving the germination rate of seeds, and further improvement is still needed to increase the germination rate of seeds
