垄向区田蓄水保土技术对大豆生长状况及产量的影响

Effects of ridge tillage's technology on growing condition and yield of soybean

垄向区田蓄水保土技术是一种坡耕地水土保持耕作措施,能够有效地拦蓄降雨径流,提高土壤含水量,从而改善作物的生长发育状况。本研究针对东北半干旱区坡耕地的自然灾害特点,在田间试验的基础上,研究了垄向区田蓄水保土技术对大豆叶面积指数、作物生长速率和净同化率的影响。研究表明,垄向区田蓄水保土技术可以有效地提高大豆的生物性状指标,从而达到高产、稳产的目的。

Ridge tillage is water conservation plowing method used in ridge plotted field, which can prohibit rain following away and increase water contend and thereby, ameliorate the condition of plants. The study aimed for the feature of calamity in semiarid area northeast, based on experimentations in field, study the ridge tillage＇s effect on leaf area index, crops growth rate and net assimilation rate on soybean. The study proofed that ridge tillage can enhance plant growing situation effectively, to the aim of harvest highly and stability.
