摘要
为了探讨育苗期间不同的环境因子对西瓜幼苗素质的影响,研究了不同光照处理、营养钵大小及磷酸二铵用量对西瓜幼苗的形态指标及生理指标的影响。结果表明,在2/3光照、直径8 cm营养钵育苗、磷酸二铵用量0.5 kg/m3的条件下,西瓜幼苗的形态指标及生理指标最好,即西瓜幼苗脯氨酸含量最低,根系活力最大,壮苗指数最大,经济效益也较高。
For the purpose of investigating the effects of different environmental factors on the quality of watermelon seedlings, the influences of different treatments in natural lighting, nutrition pot volume and diammonium phosphate rate on the physiological and morphological indices of watermelon seedlings were studied. The results indicated that under the conditions of 2/3 natural lighting, 8 cm of nutrition pot and 0. 5 kg/m3 of diammonium phosphate, the physiological and morphological indices of watermelon seedlings were the best, i. eo the lowest praline content, the highest root activity and seedling index, and also the better economic benefit.
