不同施肥处理对甜瓜钙、锌、硒营养元素含量和品质的影响

Effects of Different Fertilization Treatments on the Content and Quality of Calcium,Zinc and Selenium Nutrients in Melon

为了改善甜瓜品质,以“莎妃”甜瓜为试验材料,在土壤施肥的基础上,配合9个不同浓度水平叶面喷施钙、锌、硒肥的处理,并以喷施清水作为对照,研究施用不同浓度钙、锌、硒肥对设施甜瓜品质和果肉钙、锌、硒含量的影响。结果表明,3次施肥后,Ca3(叶喷钙肥0.500 g/L+667m^(2)土壤施钙5 kg)处理效果最佳;Zn2(叶喷钙肥0.870 g/L+667m^(2)土壤施锌800 g)处理较对照含锌量增加了45.9%,富锌效果明显;Se2(叶喷硒肥0.010 g/L+667m^(2)土壤施硒200 g)、Se_(3)(叶喷硒肥0.005 g/L+667m^(2)土壤施硒100 g)处理不仅能够改善甜瓜品质,而且果肉富硒效果显著;综合各项指标及成本,考虑推荐施用Ca3、Zn2和Se_(3)处理双补施肥方法分别为富钙、富锌和富硒最佳配比。

In order to improve the quality of melon,'Shafei'was used as the test material,and the soil application was combined with 9 different concentration levels of foliar spraying calcium,zinc and selenium as treatments and spraying water as control,to study the effects of different concentrations of calcium,zinc,and selenium fertilizers on melon quality and the contents of calcium,zinc and selenium in flesh.The results showed that after three fertilizations,Ca3(foliar spraying calcium 0.500 g/L+soil calcium 5 kg per 667m^(2))treatment had the best effect,Zn2(foliar spraying zinc 0.870 g/L+soil zinc 800 g per 667m^(2))treatment increased the content of zinc by 45.9%compared to the control,the zinc-rich effect was obvious.Se2(foliar spraying selenium 0.010 g/L+soil selenium 200 g per 667m^(2)),Se_(3)(foliar spraying selenium 0.005 g/L+soil selenium 100 g per 667m^(2))treatments could not only improve the quality of melon,but also had a significant effect of selenium-rich in flesh.Taking into account the various indicators and costs,it recommended Ca3,Zn2 and Se_(3) treatments as the best calcium-enriched,zinc-enriched and selenium-enriched fertilization methods.
