以Galia甜瓜为试材,春季试验设在以色列北部,秋季试验设在西部的约旦河谷地。研究结果表明,春季应用2～4mg/1 PP333对混合基质移栽苗浸根,并结合使用乙烯利,在不同栽植密度下可增加甜瓜产量15%～20%,只是减少了早期产量。产量的增加归因于单个瓜重的增加,并非瓜数的增多。总的看法是,PP333改善了商品瓜产量,使产量集中,纯收入增加。秋季使用浓度为250mg/1,从开花期到果实成熟期进行喷布,以喷10mg/1 BA 作对照,并结合喷 N、P、K 营养元素。研究结果显示:秋季喷 PP333减少了早期叶色变黄症状,而 BA 对此没有影响。此外,秋季喷布对甜瓜产量或产量构成没有影响,但对甜瓜的可溶性固形物含量有明显增加,而其他品质保持不变。
Galia melon was used as test material, the spring test was located in northern Israel, and the autumn test was located in the western Jordan Valley. The results showed that the application of 2 ~ 4mg / 1 PP333 in spring mixed root transplanting seedlings root, and the combination of ethephon, at different planting densities can increase the yield of melon 15% to 20%, only to reduce the early yield. The increase in output is attributed to a single increase in weight, not the increase in the number of melons. The general idea is that PP333 improves the yield of commercial melons, concentrates the output and increases the net income. The concentration in autumn was 250mg / 1, which was sprayed from the flowering stage to the fruit ripening stage, sprayed with 10mg / l BA as the control, and sprayed with N, P and K nutrients. The results showed that spraying PP333 in autumn reduced the symptoms of early leaf color yellowing while BA had no effect on it. In addition, fall spray had no effect on melon yield or yield composition, but significantly increased soluble solids content of melon, while other qualities remained unchanged.
