生物炭对番茄幼苗生长及养分吸收的影响
Effects of Biochar on Growth and Nutrient Uptake of Tomato Seedlings
摘要
Abstract
The experiment studied the effects of biochar addition on tomato seedling growth and nutrient uptake by adding biochar with different ratio (1:1 mixture of wheat straw and peanut shell carbonized by high temperature)into tomato nursery substrate. The result indicated that adding biochar (10%-30%) could improve vent ability,reduce unit weight,increase pH value and EC value of nursery substrate. Compared with the contrast,adding 20% biochar could significantly improve the stem thickness,healthy seedling index,root-shoot ratio,chlorophyll content and root system activity of tomato seedlings by 24.29%,62.87%,31.29%,54.87% and 26.86%,respectively.Besides,biochar addition in nursery substrate could also increase the absorption and accumulation of N,P and K nutrients by tomato seedlings,which was very helpful for tomato seedling growth.关键词
