瓜类种子进行播前处理,可防治病虫,增强抗旱、抗寒、提高产量和品质。 一、浸种。消灭种子表面病菌,缩短发芽和出苗时间,提高发芽率。 1.变温浸种。将瓜类种子放入53～56℃的温水中,不断搅拌15分钟,然后自然冷却并持续4～6小时,如果没有温度表,可根据种子多少用2份开水加一份室温下的冷水,水温大约为55℃左右。 2.恒温浸种。瓜类种子种皮厚,透水性差,播前可用25～30℃左右的温水,在
Melon seeds for pre-sowing can prevent pests and diseases, enhance drought, cold, improve yield and quality. First, soaking. Eliminate the germs on the seed surface, shorten the germination and emergence time, improve germination rate. 1. Variable temperature soaking. The melon seeds into 53 ~ 56 ℃ warm water, stirring constantly 15 minutes, and then naturally cooled and continued for 4 to 6 hours, without a thermometer, according to the number of seeds with 2 copies of boiling water plus a room temperature cold water, The water temperature is about 55 ℃. 2 soaking temperature. Melon seeds, seed coat thick, poor water permeability, available 25 ~ 30 ℃ before sowing warm water
