Method of preparing preparation for promoting pollination and fruit setting of xeromorphic crop by Trichodermaharzianum solid fermentation

Abstract

The invention discloses a preparation for promoting pollination and fruit setting of xeromorphic crop by Trichodermaharzianum solid fermentation, a method and application thereof. The method comprises the following steps of: (1) preparing a solid culture medium; (2) inoculating Trichodermaharzianum spores on the culture medium, and evenly stirring to obtain a fermentation basic material; (3) covering a plastic cloth on the fermentation basic material, inputting filtered air, fermenting for 5-7days at 26-30 DEG C, turning out the material in the fermentation process, changing the filtered air regularly, keeping the humidity at 72-78%; and (4) opening the plastic cloth, cooling to the room temperature, drying in the air, reducing the water content to 10-15%, drying, and grinding into particle fermented material which is the organic fertilizer for promoting the pollination and fruit setting of xeromorphic crop. The preparation can increase the yield of vegetables, corns, cucumbers and rice respectively by 20%, 15%, 28% and 5.3%; the solid fertilizer is additionally applied to increase the yield of wheat by more than 10% and double the yield of oil tea when the dosage of urea for eachmu of arable land is halved.

Description

technical field [0001] The invention belongs to the field of biological fertilizers, and in particular relates to a method for producing a preparation for promoting pollination and fruit setting of xerophytic crops by solid fermentation of Trichoderma harzianum. Background technique [0002] Trichoderma (Trichoderma.Spp) belongs to the half-knowledge fungi of the class Synmycetes, and it is widely present in ecological environments such as soil, plant root circles, seeds, leaf margins, and rotten wood. Due to the wide adaptability, broad spectrum and multi-mechanism of Trichoderma, according to the long-term research results of the patent applicant of the present invention, Trichoderma has not only been the key research object of plant disease biocontrol scientists, but also has the purpose of using physical methods. transformation (such as N + Beam, ultraviolet, γ-ray irradiation and other techniques), the Trichoderma mutant strain (H-13) isolated and screened from rotten ...

Problems solved by technology

During the use of chemical fertilizers, the soil structure and microbial growth environment are destroyed, which affects the decomposition and utilization of nutrients by soil microorganisms, and is not conducive to the absorption of nutrients by plants.
