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