2010-2020年鲁西南粘质潮土区小麦玉米周年秸秆还田粮食产量与土壤养分数据集

A dataset of grain yield and soil nutrient of wheat and maize in fluvo-aquic clayey soil region of Southwest Shandong Province based on the annual straw returning to the field from 2010 to 2020

潮土是鲁西南黄河冲积平原主要土壤类型,其中粘质潮土占比近20%,具有土壤质地粘重,结构性差,有效含水量低,适耕期短,养分矿化慢等特征,需要进行改良。目前其常规改良措施主要是靠增施有机物。秸秆还田作为增施有机物的手段,是改良粘质潮土的重要措施。本数据集依托实施沃土工程项目,选择菏泽市牡丹区农作物原种场(现为菏泽市牡丹区种子资源开发保护中心,下同),在常规生产的条件下,连续11年跟踪监测小麦玉米轮作周年秸秆还田土壤养分变化,以期探索大田秸秆还田条件下鲁西南土壤养分与粮食产量的变化规律,为黄淮海平原推广秸秆还田,培肥土壤肥力,稳定粮食生产提供科学依据。

The fluvo-aquic soil is the main soil type in the Yellow River alluvial plain in Southwest Shandong Province,among which the clayey fluvo-aquic soil accounts for nearly 20%.The fluvo-aquic clay soil needs to be improved,as a result of inferior quality,such as heavy texture,poor soil structure,low effective water content,short cultivable period,slow process of nutrient mineralization,etc.At present,the conventional improvement has to rely on the application of organic matter.Straw returning,as a means of increasing organic matter,is an important measure to improve clayey fluvo-aquic soil.Based on the implementation of the fertile soil project,we selected the Original Crop Seed Farm in Mudan District,Heze City(now,the Seed Resource Development and Protection Center of Mudan District,Heze City)to monitor the changes of soil nutrients in wheat and maize rotation based on the straw returning to the filed for 11 years under the condition of conventional production.The dataset is aimed to explore the change law of soil nutrients and grain yield under the condition of straw returning to the field in Southwest Shandong Province,and to provide scientific basis for promoting straw returning to the field,increasing soil fertility and stabilizing grain production in the Huang-Huai-Hai Plain.
