Problems solved by technology

The harsh soil environment will lead to a great reduction in the number of effective viable bacteria after application, resulting in low effectiveness; or the use of nutritional package fertilizers requires the simultaneous application of corresponding base fertilizers, soil conditioners, bio-organic fertilizers, microbial agents and humic acid-containing fertilizers. A total of 5 liquid fertilizers can effectively improve the survival rate of strawberry seedlings. The method is complex, costly, and long-term

Abstract

The technical scheme of the invention discloses an anti-replant problem soil conditioner for greenhouse strawberries. The soil conditioner comprises the following components in percentage by mass: 39-48% of activated silicon, 2-3% of a water-retaining agent, 25-30% of microbial bacteria and carriers thereof and 25-28% of trace elements. The soil conditioner provided by the technical scheme of theinvention can still keep higher biological activity after being applied, has a remarkable prevention and treatment effect on soil-borne diseases of greenhouse strawberries, is simple and convenient toapply, and can achieve a better prevention and treatment effect on the soil-borne diseases of the greenhouse strawberries by one product.

Description

technical field [0001] The invention relates to the field of soil conditioners, in particular to a soil conditioner resistant to repeated cropping of strawberry and a preparation method thereof. Background technique [0002] Continuous cropping diseases of strawberry are the main factors affecting strawberry production at present. The mild ones lead to yield reduction, and the serious ones even result in a failure of harvest. At the same time, the survey showed that more than 50% of the strawberry diseased plants in the facility greenhouses were affected, and more than 35% of the strawberry diseased plants in the open field were also affected. The main cause of continuous cropping obstacles is disease, followed by deterioration of soil physical and chemical properties and lack of nutrient elements. If beneficial bacteria are dominant in the crop rhizosphere, soil-borne diseases of plants will not occur; Changes in environmental, chemical, mechanical and other factors may a...
