摘　　要：为了筛选出适宜旱砂田西瓜栽培的育苗基质配方,以西瓜品种硒砂瑞宝为供试材料,以V_(草炭)꞉V_(蛭石)=2꞉1的传统育苗基质为对照,在此基础上添加0.3%的保水剂、不同比例的有机肥和缓释肥配成9个处理,研究了不同配方基质对西瓜穴盘苗生长的影响。结果表明,西瓜幼苗生理生长指标总体表现出随有机肥比例的增加而提高、随缓释肥比例的增加先提高后降低的变化趋势。其中,T8处理的西瓜幼苗生理生长指标最优,与CK相比,植株茎粗、茎叶鲜质量分别显著提高15.45%、82.49%;总根长、根表面积分别显著提高42.73%和95.57%,壮苗指数显著提高79.78%。因此,T8(V_(草炭)꞉V_(蛭石)=2꞉1,10%鸡粪+0.6%缓释肥+0.3%保水剂)为旱砂田西瓜最优育苗基质配方。The effect of different soil mix,standard soil mix with 0.3%water-retaining agent,organic fertilizer and slow-release fertilizer proportionally added,on seedling quality for dry sandy land watermelon production was tested using watermelon variety XiSha RuiBao and standard soil mix 2 peat:1vermiculite as the control.The results showed that the seedling physiological growth index improved with the increase of organic fertilizer proportion in the soil mix.Slow-release fertilizer was beneficial at lower rate.Compared with CK,seedling stem diameter,fresh weight,root length,root surface area and seedling strength index grown on T8 soil mix were increased by 15.45%,82.49%,42.73%,95.57%and 79.78%,respectively.Therefore,T8 mix(2 Peat꞉1 vermiculite,10%chicken manure,0.6%slow-release fertilizer,0.3%water retaining agent)is the best mix formula for seedling for watermelon production on dry sandy land.
