Organic preparation for disinfecting flower continuous cropping obstacle sick soil and application thereof

Abstract

The invention relates to an organic preparation for disinfecting flower continuous cropping obstacle sick soil and application thereof. The preparation is a composition of dry plant powder of reeds, potato vines, rice straws, wheat straws, bagasse, bean dregs, broad bean straws, corn straws and the like and molasses, wherein the weight percent of the molasses is 0-100%, and the dry plant powder and the molasses are respectively packaged prior to use and then successively used. The application method is as follows: uniformly spreading the dry plant powder or the molasses on a continuous cropping obstacle flower field according to a preset ratio, and ploughing to bury the plant powder or the molasses into a soil plough horizon; uniformly watering according to a ratio of 30-80 tons of water per mu to keep the soil wet, and covering a film on the ground to isolate the soil from air; controlling the soil temperature at 25-50 DEG C, and enabling the oxidation-reduction potential to reach -60 mv or below so as to form an anaerobic strong reducing state; and keeping the anaerobic strong reducing state for 3-4 weeks, and then removing the covering film. The organic preparation provided by the invention can effectively kill Fusarium oxysporum, Meloidogyne and the like in the soil after flower planting, eliminate continuous cropping obstacles and restore soil characteristics.

Description

technical field [0001] The invention relates to a flower planting technology, in particular to an organic preparation for disinfection of diseased soil in flower continuous cropping obstacles and its application. Background technique [0002] As a kind of crop, flowers have been artificially planted for a long time. Especially in modern times, with the improvement of people's living standards and the pursuit of a better spiritual life, flowers are more regarded as symbols of love, friendship, career prosperity, and good luck. Consumption The quantity is getting bigger and bigger, so flower planting has become an industry. Large tracts of arable land are used to grow all kinds of flowers, and they are planted in greenhouses year after year to meet the growing market demand. [0003] Due to the ubiquitous continuous cropping obstacles of crops, the soil fertility of the land where flowers are planted has declined, soil-borne diseases have increased, and the yield and quality o...
