【摘要】：為合理運用熱帶農(nóng)業(yè)廢棄物改良酸性土壤,采用室內(nèi)培養(yǎng)試驗研究了加入15 g/kg和45 g/kg的椰炭、蔗炭、膠炭和蕉炭對橡膠園土壤酸度及交換性能的影響。結(jié)果表明:除加入蔗炭15 g/kg在培養(yǎng)第9 d、30~60 d和蔗炭45 g/kg的處理在培養(yǎng)第45 d外,四種生物質(zhì)炭在兩種添加量下在各培養(yǎng)時間內(nèi)土壤pH均顯著高于對照,土壤p H提升效果為蕉炭膠炭椰炭蔗炭,且不同生物質(zhì)炭處理之間土壤p H提升效果差異顯著;除添加蔗炭15 g/kg的處理外,其余三種生物質(zhì)炭兩種加入量均顯著降低了土壤交換性酸和交換性鋁含量,而土壤交換性氫僅在加入蔗炭45 g/kg和蕉炭15 g/kg、45 g/kg的處理上顯著低于對照;此外,蕉炭、椰炭、蔗炭顯著提高了土壤陽離子交換量和土壤鹽基飽和度,但膠炭僅提高了土壤鹽基飽和度。上述結(jié)果表明,蕉炭、膠炭、椰炭和蔗炭等熱帶農(nóng)業(yè)廢棄物生物質(zhì)炭能提高橡膠園土壤p H,降低土壤交換性酸和交換性鋁含量,從而改善橡膠園土壤酸度條件。同時,以上生物質(zhì)炭也能提高土壤陽離子交換量和土壤鹽基飽和度�？梢�,蕉炭、膠炭、椰炭和蔗炭等熱帶農(nóng)業(yè)廢棄物生物質(zhì)炭可用于改良熱帶橡膠園酸性土壤,但不同種類生物質(zhì)炭及其用量在土壤改良效果上存在差異。
[Abstract]:In order to improve the acid soil with tropical agricultural waste, the coconut charcoal and sugarcane charcoal of 15 g / kg and 45 g / kg were studied by indoor culture experiment. The effects of gum charcoal and banana charcoal on the acidity and exchange properties of the soil in rubber plantation were studied. The results showed that the addition of 15 g / kg of cane carbon at the 9th day of culture and 45 g / kg of carbon on the 9th day of culture were carried out on the 45th day. The soil pH of the four kinds of biomass carbon was significantly higher than that of the control under the two kinds of biomass carbon addition, and the effect of soil pH enhancement was significantly different among different biomass carbon treatments, and the effect of increasing soil pH was as follows: (1) the soil pH of the four biomass carbon was significantly higher than that of the control under the two kinds of biomass carbon addition. Except for the treatment of 15 g / kg sugarcane carbon, the content of exchangeable acid and exchangeable aluminum in soil was significantly decreased by adding the other three kinds of biomass carbon, while the content of soil exchangeable hydrogen was significantly lower than that of the control in addition of 45 g / kg sugarcane carbon and 15 g / kg Canna carbon (45 g / kg). In addition, banana charcoal, coconut charcoal and cane charcoal significantly increased soil cation exchange capacity and soil base-base saturation, but rubber charcoal only increased soil base-base saturation. Biomass charcoal, a tropical agricultural waste such as coconut charcoal and cane charcoal, can improve soil pH, decrease exchangeable acid and exchangeable aluminum content, and improve soil acidity. The above biomass carbon can also improve the cation exchange capacity and the saturation of soil base. It can be seen that some tropical agricultural waste biomass carbon, such as banana charcoal, gum charcoal, coconut charcoal and cane charcoal, can be used to improve the acid soil of tropical rubber plantation. But different kinds of biomass charcoal and its dosage have different effects on soil improvement.
