摘要

摘要猪液浆(PS)中所含的营养物质使其残渣成为一种潜在的有机肥,可用于树种的种植,用于木材生产,促进循环经济。本研究旨在评价连续3年施用PS的大桉杂交无性系土壤化学参数、营养状况及发育状况。评估的处理是不受精(C);矿物肥(NPK) - 02-30-10配方300 kg ha-1年1;200 m3 ha-1年(FPS200)施肥;以400 m3 ha-1年(FPS400)施肥。对叶片和土壤中的宏量元素和微量元素进行了评价。用胸径(DBH)和总高(Ht)分析树木发育情况。PS处理导致叶片K、P积累量增加,N、Ca、M、S、Cu和Fe积累量减少。FPS200和FPS400处理的胸径和Ht均等于或优于矿物施肥处理。施用NPK、FPS200和FPS400后,胸径分别比对照增加了16%、27%和30%。在土壤化学性质方面,与其他处理相比,施用磷肥降低了土壤pH值,提高了磷含量。微量营养素值足以维持生育力,未观察到潜在有毒元素积累达到被认为有害的水平。PS在杂交尤加利上的应用证明是一种有吸引力的提高木材产量的替代方法。

PIG SLURRY IMPROVES THE PRODUCTIVE PERFORMANCE OF EUCALYPT AND EXCEEDS THE MINERAL FERTILIZATION
ABSTRACT The nutrients contained in the liquid pig slurry (PS) make this residue a potential organic fertilizer for the cultivation of tree species for the production of wood, which can promote the circular economy. This research aimed to evaluate soil chemical parameters, nutritional status, and development of hybrid eucalyptus clone urograndis from PS application for three consecutive years. The treatments evaluated were without fertilization (C); mineral fertilization (NPK) – 300 kg ha-1 year1 of the 02-30-10 formulation; fertigation with PS of 200 m3 ha-1 year1 (FPS200); and fertigation with PS of 400 m3 ha-1 year1 (FPS400). Macronutrients and micronutrients from leaves and soil were evaluated. Tree development was analyzed using stem diameter at breast height (DBH) and total height (Ht). PS treatments resulted in leaves with higher accumulation of K and P and lower accumulation of N, Ca, M, S, Cu, and Fe. The treatments FPS200 and FPS400 presented DBH and Ht equal or superior to the mineral fertilization. Fertilizations with NPK, FPS200, and FPS400 resulted, respectively, in DBH increments 16, 27, and 30% higher than the control. Regarding the chemical attributes of the soil, the use of PS reduced the pH of the soil and increased the levels of P in comparison with the other treatments. The micronutrient values were adequate for fertility and no accumulation of potentially toxic elements at a level considered harmful was observed. The application of PS in eucalyptus hybrid urograndis proved to be an attractive alternative to increase wood production.
