摘要

有机施肥有利于改善土壤的物理和化学属性,并促进将被丢弃在环境中的废物的利用。本研究旨在确定兔粪堆肥(RMC)在生菜基质生产中的适当水平。试验采用完全随机设计,每10个重复,采用0%、25%、50%、75%和100% RMC与商业基质混合5个处理,在塑料盆中植入。分析变量为单株叶片数、茎部绿物质、根绿物质、茎部干物质和根干物质。随着基质中RMC掺入量的增加,叶片数量增加,达到59.46%。茎部绿物质对RMC的61.42%响应最佳。之后,这两个变量都出现了下降。在RMC剂量为36.14%时,根部绿物质开始增加,随后下降,再次增加,但没有达到曲线开始时的相同值。茎部干物质随RMC添加量的增加而增加,最高可达45.09%,随后下降。根部绿色物质增加到RMC的25%左右,稳定在堆肥的75%。一般来说,接近60%的RMC与基质混合呈现出最好的效果。我们可以得出结论,RMC可以用来促进更多的叶片,这是生菜栽培中经济上可行的部分。

Use of rabbit manure in lettuce culture: an alternative option
ABSTRACT Organic fertilization favors the physical and chemical attributes improvement of the soil and promotes the use of waste that would be discarded in the environment. This study aimed to identify the appropriate levels of rabbit manure compost (RMC) from rabbit farming in the production of substrates for lettuce. The experiment was implanted in plastic pots using 5 treatments: 0%, 25%, 50%, 75% and 100% of RMC mixed with commercial substrate, in a completely randomized design with 10 replications. The analyzed variables were number of leaves per plant, shoot green matter, root green matter, shoot dry matter and root dry matter. There was an increase in number of leaves with the increase of the RMC doses incorporated into the substrate, up to the dose of 59.46%. The shoot green matter had its best response on 61.42% of RMC. In both variables there was a decline afterwards. The root green matter started with an increase up to the dose of 36.14% of RMC, followed by a decline, and another increase, not reaching the same values obtained at the beginning of the curve. An increase was observed in the shoot dry matter as the amount of RMC increased, up to the limit of 45.09%, and then declined. The root green matter showed an increase until approximately 25% of RMC, stabilizing on 75% of the compost. In general, values close to 60% of RMC mixed with the substrate presented the best results. We can conclude that the RMC can be used to promote a greater number of leaves, which are the economically viable parts of lettuce culture.
