Problems solved by technology

However, a large number of pesticides are used, and there are drug residues and environmental pollution.
Do not apply a large amount of pesticides, and the green three-dimensional comprehensive prevention and control technology has a stable control effect of more than 90% of soft rot in large areas. There is no method

Embodiment 1

[0040] Konjac soft rot green comprehensive prevention three-dimensional supporting cultivation method:

[0041] The planting point of this embodiment is located in Chuandong Village, Nanping Township, Lichuan City, Enshi Prefecture, Hubei Province, with an area of ​​10 mu.

[0042] (1) Taro seed treatment:

[0043] Before the konjac seedlings were poured, the plots with good growth of konjac were selected in Chuandong Village, Nanping Township, Lichuan City, Enshi Prefecture, Hubei Province as the provenance, and sporadic diseased ones were excavated, and lime was sprinkled around the excavated plots. Harvest and dig konjac in mid-November. Choose taro with no damage, no mildew, no scar, flat mouth, small nest, thick terminal bud, smooth surface, spindle-shaped appearance, neat bud embryo, and 100g-200g in size for seed taro. Use 25g agricultural streptomycin (72% soluble powder 3500 times liquid) + 200g thiophanate-methyl (40% colloidal suspension 400 times liquid) per mu to...

Embodiment 2

[0058] Experimental planting of thousands of acres in Fengxiang County, Baoji City, Shaanxi Province has achieved relatively satisfactory results. The area is 500 mu.

[0059] (1) Taro seed treatment:

[0060] In mid-September, before the konjac seedlings are poured, the plots with good growth of konjac are selected as the seed source, and those with sporadic disease are dug first.

[0061] In mid-November, choose sunny weather to harvest konjac at noon, choose konjac small tubers or roots with no damage, no mildew, no scars, flat mouth, small nest, thick terminal buds, smooth surface, spindle-shaped appearance, and neat germ embryos The stems are used as taro seeds and graded, and the size of each grade is basically the same. The size of the taro is preferably 100g-500g. Dig out the taro and spread it out, dry it to make the konjac lose about 10% of the water (the soil outside the konjac will fall off naturally), after the size of the taro is graded, use 20g of potassium pe...

Abstract

The invention discloses a stereoscopic matching cultivation method for greenly and comprehensively preventing and controlling a konjak soft rot disease. The method disclosed by the invention mainly comprises the following measures of konjak seed treatment, soil treatment, biomimetic condition cultivation and field management. By usage of the stereoscopic matching cultivation method for greenly and comprehensively preventing and controlling the soft rot disease provided by the invention, the pest-disease prevention and control problems in the konjak cultivation process can be effectively solved in respective aspects by utilization of a green comprehensive prevention and control matching technology through utilizing controlled release compound fertilizers, NEB, microbial function fertilizers and Nashi 778 inducers. The stereoscopic matching cultivation method for greenly and comprehensively preventing and controlling the konjak soft rot disease has the advantages that the incidence of the soft rot disease is controlled below 6%, no pesticide residual exists, and the multiplication coefficient reaches 7-9 times.

Description

technical field [0001] The invention relates to the technical field of crop planting technology, in particular to a three-dimensional matching cultivation technology method for green comprehensive prevention and control of konjac soft rot. Background technique [0002] Since the 1980s, Chinese konjac has begun to develop industrially, but due to the late start, there has been no major breakthrough in planting technology, especially in the prevention of konjac soft rot. Can watch production cut or no harvest. [0003] With the expansion of konjac planting scale, the incidence of soft rot remains high. Especially konjac soft rot, the yield loss caused is generally 30%-50%, and severe cases can reach 80%, or even no harvest. The pathogens carried by seed taro are the main source of pathogens that cause disease in new areas of konjac after long-distance planting; the pathogens carried by seed taro and the pathogens existing in the soil make konjac pathogenic through root syste...
