Abstract

The invention discloses a soil conditioner for acid regulation and disease control and its application, relates to the technical field of soil acidification improvement and bacterial wilt prevention and control, and comprises the following components: plant ash, oyster powder, sodium metasilicate, wherein plant ash, oyster powder, The mass ratio of sodium metasilicate is (1-7):1:(0.02-0.08). The invention utilizes the synergistic enhancement effect of the three materials of plant ash, oyster powder and sodium metasilicate to improve soil acidification, regulate and reduce the occurrence of crop bacterial wilt. The present invention selects a more novel natural biomass soil acid-adjusting composite material, and the results of multiple tests show that the soil conditioner can effectively increase the pH value of the soil and regulate the occurrence of bacterial wilt.

Description

technical field [0001] The invention relates to the technical field of soil acidification improvement and bacterial wilt prevention and control, in particular to a soil conditioner for acid regulation and disease control and application thereof. Background technique [0002] In recent years, soil acidification has become an important problem in agricultural production, which seriously limits the sustainable development of agriculture in our country. In the past 50 years, my country's main farmland, grassland and forest have also experienced significant soil acidification. The main source of acidification of cultivated land is the continuous use of large amounts of chemical fertilizers (nitrogen fertilizers). The acidification caused by the application of chemical fertilizers is 10- 100 times. [0003] Acidification is one of the important signs of soil quality degradation. At present, soil acidification has become a prominent problem in agricultural production in my country....
