用特效植物营养素(SPNE)对果实有核的龙眼、无核的柿和桑果树进行不同处理,研究了SPNE在几种果树上的应用效果。结果表明,SPNE能提高果实的产量和品质,使果实增大但果核大小和重量却略有降低。SPNE在提高果实产量的同时,还提高了果实的可溶性固形物含量;能提高果树扦插生根率,使扦插难生根的鸡心柿生根成苗,而且在3年后扦插树结的果实明显大于未用SPNE处理的同龄嫁接树;用SPNE处理桑果树1年后,其果实产量及生长都全面超过清水对照,SPNE的效果具持续性。
The effect of SPNE on several fruit trees was studied by using SPNE to treat the longan fruit with nuclear, non-nuclear persimmon and mulberry fruit tree. The results showed that SPNE can increase the yield and quality of fruit, increase the fruit size but slightly reduce the size and weight of the kernel. SPNE can increase the soluble solid content of fruit while increasing the fruit yield. It can increase the rooting rate of cuttings, and make the cuttings of hardwood root persimmon take root, and the fruit of cutting cuttings after 3 years is obviously larger than the unused SPNE treatment of the same age grafting tree; with SPNE treatment of mulberry tree 1 year after the fruit yield and growth are more than clear water control, SPNE effect is persistent.
