深松对土壤含水量和玉米产量的影响

摘要

s:The change of maize yield and yield components,the soil moisture content in deep loosing tillage. The result show that deep loosening of the soil moisture significantly higher than without loosing tillage,pro-duce more than 7.96%.Deep loosening under the conditions of kernel numbers and effective ear numbers were significantly higher than without loosing tillage,both reached the significant level.So deep loosening could increase soil moisture,the corn root absorption under the top layer of soil nutrients and moisture,also increase the ear of corn grain number and effedtive panicle number,so as to help improve the quality of pro-duction.%通过深松处理，研究其对土壤含水量、玉米产量及产量构成因素的影响。结果表明：深松处理的土壤含水量明显高于未深松处理，其产量也比未深松处理高，增产比例达到了7．96％，产量构成因素中穗粒数和有效穗数明显高于未深松处理，二者均达到了显著水平。由此可知，深松可以增加土壤含水量，改善土壤结构，有利于玉米根系对深层土壤水分的吸收，保证玉米生长关键期的水分供应，增加玉米穗粒数和有效穗数，从而有助于产量的提高。
