施用不同配方有机肥对土壤物理性状及油茶生长影响

Abstract

为了进一步验证生物有机肥肥效，准确筛选出油茶有机肥配方，并为进一步优化有机肥配方提供依据，将9种配方有机肥进行油茶大田肥效试验。经过2年连续试验后，分析油茶林地土壤物理性状，比较生物量增长及产量相关指标，结果表明：在0~40 cm土壤物理性状方面，施配方5有机肥土壤容重较小(1.33 g/cm3)，土壤含水量最高(13.03%)，土壤最大含水量最高(25.40%)，土壤田间持水量最大(19.96%)；在生物量增长方面，施配方7有机肥油茶地径的增长最迅速，施配方8有机肥高与冠幅增长最明显；在产量方面，施配方9有机肥茶果大小和籽重都最大，施配方1有机肥果重和籽水量都最大，施配方5有机肥籽含水量较低，出仁率较高，施配方6有机肥出籽率最高，施配方8有机肥仁出油率最高。综合分析来看，配方5和8有机肥油茶大田实验表现较优。 In order to verify the bio-organic fertilizer effect, filtrate formula of organic fertilizer for Camellia oleifera and optimize the formula of organic fertilizer further, the experiment applied 9 kinds of organic fertilizer on Camellia oleifera. After 2 years of continuous test, we analyze the soil physical properties, and compare the growth and yield of the biomass or other related indicators. The result shows: in the aspect of soil physical properties (0 - 40cm), when fertilized with formula 5, there was smaller soil bulk density (1.33 g/cm3), highest Soil moisture content (13.03%), the highest soil maximum moisture content 25.40% and the soil field capacity is the largest 19.96%. In the aspect of production: when fertilized with formula 9, the fruit size and seed weight of organic tea was the biggest. When fertilized with formula 1, fruit weight and seed water is the largest. When fertilized with formula 5, seed moisture content is low and the kernel percent is higher. When fertilized with formula 6, the cone rate of seed is higher. When fertilized with formula 8, the oil yield efficiency is highest. In summary, formula 5 and formula 8 of or-ganic fertilizer for Camellia oleifera field have a better experimental performance.
