Fertilizer for resisting trichosanthes kirilowii root knot nematode disease, as well as preparation and use method of fertilizer

Abstract

The invention relates to a fertilizer for resisting trichosanthes kirilowii root knot nematode disease, as well as preparation and a use method of the fertilizer. The fertilizer comprises the following components in parts by mass: 8 to 10 parts of monoammonium phosphate, 10 to 12 parts of potassium sulfate, 10 to 20 parts of calcium superphosphate, 40 to 50 parts of an organic fertilizer, 8 to 10 parts of humic acid, 20 to 30 parts of tea fruit peel powder, 20 to 30 parts of camellia seed cake powder. and 5 to 10 parts of lime, wherein the organic fertilizer is a product prepared by mixing 50 to 60 parts by mass of rapeseed cake, 40 to 50 parts by mass of fungus dregs and 20 to 30 parts by mass of animal manure uniformly and stacking and composting the mixed materials under the conditions that the moisture content of the mixed materials is 40 to 50 percent by weight and the temperature is 50 to 65 DEG C. When the fertilizer serves as a trichosanthes kirilowii base fertilizer, the application amount is 200 to 300 kg / 667m<2>, and the fertilizer is applied by digging a strip-shaped ditch or annular ditch at one time before germination; when the fertilizer serves as trichosanthes kirilowii topdressing, the application amount at each time is 50 to 150 kg / 667m<2>, the fertilizer is applied by digging an annular groove at the position with 50 cm distance from root tubers, the first-time topdressing is applied when the height of seedlings is 30 to 50 cm, the second-time topdressing is applied at the early flowering stage, and the third-time topdressing and trichosanthes kirilowii overwintering hilling are conducted simultaneously.

Description

technical field [0001] The invention relates to the technical fields of fertilizer and root-knot nematode prevention and control, in particular to a fertilizer capable of effectively resisting Trichopinia chinensis root-knot nematode and its preparation and use methods. Background technique [0002] Nematodes are a class of invertebrates with bilateral symmetry and a protocoel with three germ layers, belonging to the phylum Nematodes. In nature, there are many kinds of nematode animals, estimated to be about 500,000 to 1,000,000 species, second only to insects in terms of species and quantity. Plant parasitic nematodes, that is, parasitic on the roots, stems, leaves, flowers, buds and fruits of various plants, causing plant nematode diseases. According to the different parts of the damage, plant parasitic nematodes are divided into root nematodes, leaf nematodes, stem nematodes and branch nematodes, among which root nematodes account for the majority. Compared with plant p...

Problems solved by technology

Agricultural control measures are difficult to implement due to the constraints of manpower and economic conditions in production; bio-nematicides are restricted in their application in production due to their stability and potency ratio; currently there are few varieties of nematode-resistant crops available for selection And the resistance is easy to lose; most of the chemical nematicides have been banned due to high toxicity, high residue and high price

There are some deficiencies in the prevention and control measures
