Abstract

The invention relates to an acid soil conditioner and a preparation technology thereof, belonging to the technical field of a soil conditioner. The acid soil conditioner comprises the following raw materials: plant ash, shell powder and medical stone powder at the weight ratio of (1-100): (1-100): (1-100). The preparation technology comprises the following steps: 1) high-temperature calcination; 2) crushing; and 3) mixing. The acid soil conditioner can change wastes into valuables, and is low in manufacturing cost, small in pollution, harmless to a human body, and capable of providing various nutritional elements for soil.

Description

technical field [0001] The invention relates to an acidic soil conditioner and a preparation process thereof, belonging to the technical field of soil conditioners. Background technique [0002] Qixia City is a county-level city under the jurisdiction of Yantai City, Shandong Province, China. It is famous for its rich apple production and is known as the "Fruit Capital". Qixia has also become a high-quality fruit producing area in China and the world. Over the past two decades, with the increasing yield of various fruits per mu, more and more chemical fertilizers have been used in orchards. Reports on soil acidification are frequently seen in newspapers, magazines and other media. The most suitable soil pH value for northern fruit tree varieties suitable for planting in Qixia area is 6.5-7.5, that is, the growth and fruiting are normal in a neutral environment. However, the survey found that 45.8% of the orchards in the Jiaodong fruit tree area had a soil pH value between 5...
