Problems solved by technology

With the expansion of artificial cultivation and large-scale planting area, the original environment and growth conditions have changed, konjac species degeneration, stress resistance decline, yield reduction, disease resistance weakened, disease incidence is higher, and some even Harvests were cut off, taro farmers lost a lot, and the occurrence and damage of diseases showed a trend of increasing year by year, which eventually led to a sharp decrease in planting area, seriously dampened farmers' enthusiasm for planting konjac, and hindered the development of local economy

Embodiment 1

[0020] A control method for konjac soft rot, comprising the following steps:

[0021] (1) Seed collection: Select flower buds and taros with an individual weight of more than 500 grams, and place them in the fine sand soil in the breeding room in early April; the fine sand soil in the breeding room is 5 cm thick, and the overlying sand is 19 cm. The fine sand is thickened to 40 cm, and after fruiting, the perianth is peeled off;

[0022] (2) Sowing: Harvest mature berries in August, scrub and remove the peel and pulp, take out the plump seeds and dry them, then mix 1 part of seeds with 4 parts of moist fine sand and germination bacteria, and put them in Store in a wooden box in a cellar or buried in a pit;

[0023] (3) Seedling raising: In March of the second spring, the seedbed was shallowly turned, and mixed with bacterial fertilizer evenly, to make a 120 cm wide furrow, planted on demand at a row spacing of 25 cm × 25 cm, covered with soil of 19 cm, and the surface was cho...

Embodiment 2

[0028] A control method for konjac soft rot, comprising the following steps:

[0029] (1) Seed collection: Select flower buds and taros with an individual weight of more than 500 grams, and place them in the fine sand soil in the breeding room in early April; the fine sand soil in the breeding room is 8 cm thick, and the sand is 23 cm above. The fine sand is thickened to 40 cm, and after fruiting, the perianth is peeled off;

[0030] (2) Sowing: Harvest mature berries in August, scrub and remove the peel and pulp, take out the full seeds and dry them, then mix 1 part of seeds with 5 parts of moist fine sand and germination bacteria, and put them in Store in a wooden box in a cellar or buried in a pit;

[0031] (3) Seedling raising: In April of the second spring, the seedbed was turned shallowly and mixed evenly with bacterial manure to make a 120 cm wide furrow, planted on demand at a row spacing of 25 cm × 25 cm, covered with 25 cm of soil, and chopped The wet straw should ...

Embodiment 3

[0036] A control method for konjac soft rot, comprising the following steps:

[0037] (1) Seed collection: Select flower buds and taros with an individual weight of more than 500 grams, and place them in the fine sand soil in the breeding room in early April; the fine sand soil in the breeding room is 3 cm thick, and the sand is 16 cm above. The fine sand is thickened to 40 cm, and after fruiting, the perianth is peeled off;

[0038] (2) Sowing: Harvest mature berries in August, scrub and remove the peel and pulp, take out the plump seeds and dry them, then mix 1 part of seeds with 4 parts of moist fine sand and germination bacteria, and put them in Store in a wooden box in a cellar or buried in a pit;

[0039] (3) Seedling raising: In March of the second spring, the seedbed was turned shallowly and mixed evenly with bacterial manure to make a 120 cm wide furrow, planted on demand at a row spacing of 25 cm × 25 cm, covered with soil 13 cm, and chopped The wet straw should be...

Abstract

The invention relates to the technical field of agricultural planting, and in particular relates to a preventing and controlling method for soft rot of amorphophallus rivieri. According to the methodprovided by the invention, under comprehensive consideration of factors of medicines, fertilizers, bacteria and an ecological environment in a farmland ecosystem affecting an occurrence of the soft rot, biocontrol bacteria, potassium polyphosphate and green manure according to a ratio of (1-3):(40-70):(120-160) are selected, and the obtained fertilizer is applied into soil to make the control effect of the soft rot of the amorphophallus rivieri stabilized at 90% or more.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for preventing and treating konjac soft rot. Background technique [0002] Konjac is a perennial herbaceous plant of Araceae, which is rich in glucomannan. Its unique physical and chemical properties have wide application and development value. [0003] As a high-efficiency crop, konjac has the most direct and obvious driving effect on farmers' poverty alleviation. It has become a characteristic income-increasing project of choice in suitable areas. It is already one of the effective ways for farmers to get rid of poverty and revitalize the local economy. With the expansion of artificial cultivation and large-scale planting area, the original environment and growth conditions have changed, konjac species degeneration, stress resistance decline, yield reduction, disease resistance weakened, disease incidence is higher, and some even Harvests were cut off, t...
