Effects of Different Soil Amendments on Root Traits of Foxtail Millet
摘要
Abstract
To alleviate the obstacles of continuous cropping of foxtail millet,the effects of different soil conditioners on the root characteristics of foxtail millet planted in continuous cropping soil were investigated.The test was conducted with 4 soil conditioners and 1 non-fertilized control treatment.Four soil improvers include self-developed formula treatment(including seaweed essence,polyglutamic acid and EDTA chelated trace elements),earthworm polysaccharide treatment,microbial agent treatment and chitooligosaccharides treatment.For each soil conditioner treatment,two fertilization gradients were set as the common dose in agriculture and the equivalent dose,a total of 9 treatments.The experiment measured the plant height,dry and fresh weight,root traits,and other related indicators of different treatments during the 7-leaf stage and booting stage.The results showed that compared to the unfertilized control(CK),all soil conditioners improved the growth of foxtail millet in continuous cropping soil.Among them,chitooligosaccharides and earthworm polysaccharides had the best effect on promoting the growth of foxtail millet roots.After treatment with chitooligosaccharides,the total length of roots increased by 87.4％to 120％,the average diameter of roots increased by 21.7％,and the total number of root tips increased by 93.8％to 144％.During the booting stage after treatment with earthworm polysaccharides,the total length of roots increased by 128％to 161.3％,the average diameter of roots increased by 4.3％to 8.6％,and the total number of root tips increased by 151.4％to 183％.In summary,chitooligosaccharides and earthworm polysaccharide could promote the growth of foxtail millet roots and alleviate obstacles to continuous cropping.This study provided a certain scientific basis for alleviating continuous cropping obstacles in production.关键词
