| Abstract: |
| To explore the effects of a kind of new soil conditioner（ named by Tebeigai，made from oyster shell
powder） on peanut yield and soil acidification in red soil，field experiment was conducted，which included four rates of soil conditioner（ 0，750，1 500 and 2 250 kg/hm2），then，peanut yield，yield components，soil chemical
properties were analyzed. The results showed that： the peanut yield in application of soil conditioner increased than
CK（ no soil conditioner） by 10.2%-23.8%， their plant height，grain number and 100-grain weight were improved
significantly. Meanwhile，compared with CK，soil available N，P and K of soil conditioner treatments increased by
21.65%-118.1%，118.1%-74.1% and 22.6%-74.1%；while the soil pH and exchange calcium of soil conditioner
treamnets increased significantly than CK by 0.18-0.33 units（ 4.0%-7.3%） and 12.9%-18.8%，and exchange
hydrogen and aluminum contents reduced than CK by 19.6%-62.5% and 34.7% 84.2%，respectively. Therefore，this
new type of soil conditioner could attain higher yield of peanut in red soil，improve soil available nutrient and reduce
soil acidification. |
