磷钾肥配施对嫁接西瓜黑翡翠产量及品质的影响

Effects of Phosphorus and Potassium on the Quality and Yield of Grafted Watermelon Heifeicui

采用大田随机区组设计,研究了同等施氮条件下,不同磷、钾肥配比对嫁接西瓜黑翡翠产量及品质的影响。研究结果表明,施尿素为417kg/hm2的条件下,磷钾肥用量对黑翡翠茎粗、主蔓长度、产量及品质均有较大的影响。其中以A1B1组合(钙镁磷682kg/hm2,硫酸钾504kg/hm2)的产量最高,达36390kg/hm2,较对照A3B3(钙镁磷367kg/hm2,硫酸钾252kg/hm2)增产4800kg/hm2,增产幅度为15.2%,且A1B1组合的可溶性固形物含量也为各处理间最高。

The effect of different quantity of phosphorus and potassium on the quality and yield of grafted watermelon Heifeicui using the randomized and grouped design of wide field was studied. The results showed that the quantity of phosphorus and potassium have significant effect on the stem diameter, the main vine length, the quality and yield of Heifeicui. Among them the highest production is A1B1 treatment （which is mixed by 682 kg/hm2 calcium magnesium phosphate and 504 kg/hm2 potassium sulfate）. The yield reached 36 390 kg/hm2, compared with A3B3 treatment （which is mixed by 367 kg/hm2 calcium magnesium phosphate and 252 kg/hm2 potassium sulfate）, increased by 4 800 kg/hm2 and the increasing rate is 15.20%. The soluble solids content of A1B1 treatment is the highest among all treatments.
