施用生物炭对灰漠土养分及棉花生长的影响
Effects of Biocar Application on Nutrient and Cotton Growth in Gray Desert Soil
摘要
Abstract
[Objective] As a kind of organic matter rich in carbon, highly aromatic and stable, biochar serves as an important way to improve soil and maintain and improve soil fertility.[Method]In the study,the cotton stalk-char(BC)was carbonized by 1 hour at 450℃ as the test material and mixed with gray desert soil under different rates of addition levels(0,1.5%,3.0%and 6.0%)to research the effect on the growth of gray desert soil nutrients and cotton.[Result]The results showed that the effect of adding cotton stalk on the whole nutrient was not obvious,but the contents of available N and available K in ash were increased by 31. 27%-44.10%and 36.4%-98.5%(P <0.05).Compared with NPK,the content of available potassium was increased by 29.4%-88.3%.CEC increased with the increase of the addition amount.The addition of cotton charcoal reduced the pH value of the soil,the decrease of 1.5 BC was more obvious and decreased by 0.13 unit;In addition,the addition of cotton stalks increased the yield of cotton significantly,which was 7. 9%-21.3%higher than that of the CK,while that of NPK was 12.4%higher than that of the CK.[Conclu-sion]The addition of cotton stalk charcoal increased the organic carbon storage and the cation exchange per-formance,soil fertility and improved the soil productivity in gray desert soil in Xinjiang.关键词
