不同有机物料对胡椒园土壤肥力性状及胡椒生长的影响

Effects of Different Organic Fertilizers on Soil Fertility and Pepper Growth in Pepper Plantation

有机肥是来源于植物或动物经发酵腐熟的含碳有机物料,因此不同有机肥养分含量存在差异,对胡椒园来说施用何种有机肥更有利于胡椒园的土壤肥力提升及胡椒生长是值得研究的一项课题。以4种有机物料为材料添加到胡椒园土壤中,研究不同有机物料对胡椒园土壤肥力性状及胡椒生长的影响。结果显示,各处理土壤pH值高低顺序为100g猪粪+4kg土(T2)>100g生物炭+4kg土(T4)>100g牛粪+4kg土(T3)>0g肥料+4kg土(T1)>100g商品有机肥+4kg土(T5),与T1相比,T2处理达显著水平;其他处理土壤有机质含量均显著高于T1;T2、T3处理对土壤碱解氮含量具有显著的提高作用;T2处理的土壤速效磷、有效钾含量极显著高于其他处理。不同处理有机肥施用对胡椒生物量、茎围、株高增加值的差异不显著,100g牛粪+4kg土(T8)处理新梢增加的数量显著高于0g肥料+4kg土(T6)处理。此项研究结果在胡椒农业生产中具有一定的指导意义。

Organic fertilizers are organic materials containing carbon that have been fermented and decomposed from plants or animals.Therefore,the nutrient content of different organic fertilizers is different,and it is worth studying which organic fertilizer is more conducive to the improvement of soil fertility of pepper plantation and growth.Four kinds of organic materials were added to the soil of pepper plantation,and the effects of different organic materials on plantation soil fertility and pepper growth were studied.The results showed that the order of soil pH values in each treatment was 100 g pig manure+4 kg soil(T2)>100 g biochar+4 kg soil(T4)>100 g cow manure+4 kg soil(T3)>0 g fertilizer+4 kg soil(T1)>100 g commercial organic fertilizer+4 kg soil(T5),while the T2 treatment reached a significant level compared with T1.And the soil organic matter content of different treatments was significantly higher than that of T1;T2 and T3 treatments had a significant effect on soil alkaline nitrogen content.The content of available phosphorus and available potassium of soil in T2 was significantly higher than other treatments.There was no significant difference in the added value of pepper biomass,stem circumference and plant height of different treatments of organic fertilizers.The difference in the number of new shoots increased between the treatment with 100 g cow manure+4 kg soil(T8)and the treatment with 0 g fertilizer+4 kg soil(T6)reached a significant level.The results of study had a certain guiding significance in the pepper agricultural production.
