黑龙江垦区玉米秸秆腐解规律试验研究
|
摘要
玉米种植在黑龙江垦区农业生产中占有重要地位,但垦区不同区域秸秆还田形式尚未形成共识,找到黑土条件下玉米秸秆还田腐解规律,对合理选择秸秆还田及玉米种植模式具有重要意义。为此,以土壤含水量、腐解时间、秸秆长度及翻埋深度为因素,设计正交试验用以确定黑土条件下秸秆腐解规律。试验结果表明:土壤含水量对秸秆腐解率影响显著;土壤含水量较低时,秸秆腐解率也较低;秸秆在秸秆翻埋早期腐解较快,90天后腐解速率下降;秸秆长度短于6cm后,腐解率提高幅度较小;随翻埋深度变浅,秸秆腐解率提高。
Corn planting is very important in agricultural production in Heilongjiang reclamation area. However,there is no consensus on the form of straw returning in different regions of the reclamation area. It is important to find the law of corn straw decomposing in the black soil for selecting the straw returning pattern. With the factors of soil water content,decomposition time,straw length and burial depth,the orthogonal test was designed to determine the rule of straw decomposition under the condition of black soil. The results showed that soil water content had significant influence on the decomposition rate of straw. Straw decomposed quickly at the early stage of straw burying,and the decomposition rate decreased after 90 days. After the length of straw was shorter than 6 cm,the decomposition rate increased slightly,and the rate of straw decomposition increased with the shallow depth of the burial.
