松土促根剂对土壤质地、冬小麦产量和淀粉糊化特性的影响
Effects of Soil Root Promoter on Soil Texture,Gain Yield and Starch Pasting Traits of Winter Wheat:a Result from a Field Experiment
摘要
Abstract
In order to solve the problem of too shallow topsoil ,bad condition of soil texture ,poor root develop-ment and decrease of yield and quality in wheat field due to years of rotary tillage in North China , based on bal-anced fertilization,a field experiment was conducted to study the effect of a soil root promoter named Agri-star on soil texture ,gain yield and starch pasting traits of winter wheat .Results showed that the application of soil root pro-moter and deep tillage could reduce soil bulk density and increase the volume of wheat root mass ,resulting in impro-ving soil physical and chemical properties .In addition ,the application of soil root promoter could improve the spike number and grain number per spike of winter wheat that caused the increase of wheat grain yield ,and the 1 soil root promoter combined with fertilizer had the highest grain yield with 7 925 kg/ha increased by 12 .9%compared with the single fertilizer application .The study also found that the treatments of formula fertilizer application , soil root promoter or deep tillage could improve starch quality of wheat grain with the best effect in the 1 soil root promoter combined with fertilizer .In a conclusion ,the application of soil root promoter-Agri-star can improve the soil texture , increase the yield of wheat ,improve starch quality of wheat grain in a certain extent ,and has broad application pros-pects under the conditions of no tillage or rotary tillage in the wheat field in North China .关键词
