Abstract

A watermelon seed treatment method being high in germination rate comprises following steps: (1) pre-treatment of seeds: soaking watermelon seeds in an acidic soaking solution with flat seeds rejected; (2) preparation of a seed soaking liquid: mixing ammonium nitrate, sodium phthalate, sodium humate, an nutrient additive liquid and gibberellins to obtain a mixed aqueous solution; (3) seed soaking: soaking the pre-treated seeds in the seed soaking liquid; (4) sterilization treatment: treating the treated seeds under an infrared light lamp and sowing the seeds after sterilization. In the invention, the seeds are subjected to the pre-treatment so that dormant period of the watermelon seeds is broken, thereby promoting germination of the watermelon seeds. The seed soaking liquid is rich in nutrients so that the watermelon seeds can go through the dormant period with a short time, so that the speed of germination and seedling of the watermelon seeds is increased. The irradiation of the infrared light achieves the sterilization effect and can enhance disease resistance of the seeds, thereby increasing the cultivation successful rate of watermelon and achieving a high germination rate.

Description

technical field [0001] The invention belongs to the technical field of seed treatment, and in particular relates to a watermelon seed treatment method with a high germination rate. Background technique [0002] In the prior art, the general method for accelerating the germination of watermelon seeds is: put the wet seeds after soaking into a cloth bag, swirl them vigorously a few times to remove excess water on the seeds, or spread the wet seeds to dry until the seed coat Put it in a wet cloth bag when it is not wet. Put the seed bag into the germination box or put it in a pot, put the pot next to the stove or on the heated kang, cover it with a quilt to moisturize, and carry out germination at a suitable temperature. The optimum temperature for germination is 25 to 32 degrees Celsius. In order to prevent the seeds from losing water too quickly, during the germination period, several layers of damp cloth should be covered on the seed bag after wringing out the water, other...
