施肥对碱化土壤及倒茬作物的影响
Effects of Different Fertilization Methods on Alkaline Soil and Inverted Crops
摘要
Abstract
The gradually salinized farmland of Fu'antun village,Liaohe Town,Horchin District,Tongliao City,In-ner Mongolia Autonomous Region was taken as the experimental area.Using wheat as the preceding crop and mustard as the following crop,four fertilization treatments were set up,such as the combined treatment of organ-ic fertilizer and chemical fertilizer(HY),the single treatment of organic fertilizer(Y),the single treatment of chemical fertilizer(H)and the control treatment without fertilizer(CK).After harvest,the difference of mustard yield,soil ion content and alkalinity degree under different fertilization treatment was investigated.The results showed that the soil calcium content under HY treatment increased by 0.11 g·kg-1,the Na+content decreased by 0.05 g·kg-1,the alkalinity decreased by 0.99%,and the yield increased by 15 791.85 kg·hm-2 compared with CK treatment.Compared with H treatment,HY treatment increased Ca2+ content by 0.07 g·kg-1,Na+ content de-creased by 0.05 g·kg-1,alkalinity decreased by 1.28%,and there was no significant difference in mustard yield.The combined application of organic fertilizer and chemical fertilizer not only reduces the content of soil base ions and the degree of alkalinity,but also significantly improves the crop yield,so as to maintain the health of soil and the green and sustainable development of agriculture.关键词
