The invention discloses a hot pepper pepper continuous cropping autotoxicity concave soil matrix restorative agent, a preparation method thereof and a seedling matrix preparation method thereof. The concave soil restorative agent comprises the following components by mass percent: 40-65% of concave soil, 25-40% of waste coal cinders, 2-8% of active carbon, 0.8-1.5% of hydrated lime and 0.5-2% of humic acid. According to the invention, the concave soil restorative agent can solve the problem that autotoxicity caused by autotoxins is difficult to eliminate by adopting traditional agronomic measures such as rotating intercropping, soil improvement and ectopic seedling, so that the formation and aggravation of continuous cropping obstacles can be effectively relieved.
Description
[0001] technical field [0002] The invention relates to the technical field of crop cultivation, in particular to an attapulgite base repair agent for continuous cropping self-poisoning of peppers, a preparation method thereof and a seedling-raising substrate preparation method thereof. Background technique [0003] The obstacle of continuous cropping has become a bottleneck restricting the sustainable development of pepper industry. The reasons for the formation and aggravation of continuous cropping obstacles are complex, and they are the external manifestations of the combined effects of many factors in the rhizosphere soil system, including: [0004] ①Soil nutrient imbalance and deterioration of soil physical and chemical properties; [0005] ② Accumulation of soil pathogenic bacteria and dysfunction of rhizosphere micro-ecology; [0006] ③ Autotoxicity caused by allelochemical substances, etc. [0007] Autotoxicity is a phenomenon in which plants release chemical su...
