New Plant Growth Regulator Emistim C AS used on Watermelon in Field Evaluation

Most plant growth regulators available are synthesized and tend to be dangerous if used inappropriately. Emistim CAS is a natural plant growth regulator, with less side-effect. The research performed an assessment on Emistim CAS application in watermelon cultivation in a greenhouse. The results showed that 0.11% Emistim CAS increased reducing sugar by 15.49%, soluble solid by 13.7%, Vc content by 3.72%, titratable acid by 18.1%, and yield per hectare by 18.01%, so that watermelon quality and yield were both improved. Emistim CAS can be widely promoted in watermelon cultivation in future.

植物生长调节剂“爱密挺”对花生生长及产量的影响

大田条件下,以花生品种花选14号为试材,研究了纯天然植物生长调节剂"爱密挺"对花生生长及产量的影响。结果表明,(1)各处理对花生个体和群体生长均有不同程度的影响,T4处理"爱密挺拌种+爱密挺开花期喷雾"的株高、单株叶面积和群体生长率最大,其次是T2处理"爱密挺拌种,"T3处理"爱密挺开花期喷雾"效果最差,但三指标也均高于对照T1。(2)各处理单株总荚数、单株果仁重和单株荚果重均较对照有所提高,百仁重降低,千克果数增加,即平均单果重降低;产量由高到低的顺序为T4>T2>T3>T1,且T4处理的产量与对照的差异达到了显著水平。表明纯天然植物生长调节剂"爱密挺"在花生上有推广应用的价值。

新型植物生长调节剂爱密廷在西瓜上的田间应用评价

[目的]明确自然源植物生长调节剂爱密廷对西瓜产量和品质的影响及其使用技术,为其田间应用提供参考。[方法]评价新颖植物生长调节剂爱密廷在温室大棚栽培西瓜上的田间应用效果。[结果]与清水对照相比,0.11%爱密廷AS 10 mg/kg能够使西瓜还原糖含量提升15.49%、可溶性固形物含量提升13.70%、VC含量提升3.72%、可滴定酸含量降低18.10%、产量提升18.01%。[结论]爱密廷对西瓜品质和产量的提升效果较显著,值得在西瓜种植上大规模推广。
