Embodiment 1

[0029] A method for disease-resistant cultivation of konjac under a low-altitude forest, the method comprising the following steps:

[0030] 1) Select the idle land under the camphor forest (Figure 1), at an altitude of 200-250 m;

[0031] 2) Plowing and leveling the under-forest land;

[0032] 3) Apply crushed dry rice straw and decomposed pig manure to the plowed soil, and the amount of dry rice straw is 0.15 kg / m 2 , decomposed pig manure (water content about 50%) 0.4 kg / m 2 ;

[0033] 4) Planting calla lilies ( Alocasia macrorrhizae (L.) Schott), 2-4 m 2 plant a plant;

[0034] 5) Plant konjac around the calla lily, the size of konjac species is 60-150 g / piece, plant 4-7 per square meter;

[0035] 6) Detect and record the growth status of konjac. The growth of konjac is normal, and there is no lodging phenomenon during the three-year growth period;

[0036] 7) Konjac tubers are harvested in the third year, and the weight of the harvested konjac tubers is 3.7 times ...

Embodiment 2

[0038] A method for disease-resistant cultivation of konjac under a low-altitude forest, the method comprising the following steps:

[0039] 1) Choose mountain miscellaneous forests, under which there are weeds and small shrubs (Figure 2), at an altitude of 300-450 m;

[0040] 2) Plowing and leveling the under-forest land;

[0041] 3) Apply fallen leaves to the plowed soil at an amount of 0.35 kg / m 2 ;

[0042] 4) Planting calla lilies ( Alocasia macrorrhizae (L.) Schott), 2-4 m 2 plant a plant;

[0043] 5) Plant konjac around the calla lily, the size of konjac species is 60-150 g / piece, plant 4-7 per square meter;

[0044] 6) Detect and record the growth status of konjac. The growth of konjac is normal, and there is no lodging phenomenon during the one-year growth period;

[0045] 7) Konjac tubers were harvested in the same year, and the number of konjac tubers harvested was 4.3 times the number of konjac seeds used for sowing. The planted konjac seeds were divided int...

Embodiment 3

[0047] A method for disease-resistant cultivation of konjac under a low-altitude forest, the method comprising the following steps:

[0048] 1) Choose a citrus forest (Figure 3), at an altitude of about 230 m;

[0049] 2) plowing and leveling the land;

[0050] 3) Apply decomposed pig manure (water content about 50%) to the plowed soil 0.5 kg / m 2 ;

[0051] 4) Planting calla lilies ( Alocasia macrorrhizae (L.) Schott), 2-4 m 2 plant a plant;

[0052] 5) Plant konjac around the calla lily, the size of konjac species is 60-150 g / piece, plant 4-7 per square meter;

[0053] 6) Detect and record the growth status of konjac. The growth of konjac is normal, and there is no lodging phenomenon during the one-year growth period;

[0054] 7) Konjac tubers were harvested in the same year, and the number of konjac tubers harvested was 3.8 times the number of konjac seeds used for sowing. The planted konjac seeds were divided into 2-8 small konjac tubers, which were used as seed taro...

Abstract

The invention relates to a method for disease-resistant cultivation of amorphophallus rivieri durieu under low-altitude forests. The low altitude of the method refers to the altitude smaller than 700 m, the amorphophallus rivieri durieu is planted under the forests including economic forests such as citrus forests and Chinese chestnut forests and commercial forests such as oak forests, fir forests and camphor tree forests, the disease-resistant cultivation means that the morbidity of seed amorphophallus rivieri durieu cultivated from planting to harvesting of the amorphophallus rivieri durieu is lower than 1%, and the soft rot disease incidence rate of the harvested amorphophallus rivieri durieu tubers is lower than 3%. The amorphophallus rivieri durieu planting area can be enlarged, the amorphophallus rivieri durieu yield is increased, and the seed amorphophallus rivieri durieu yield is increased.

Description

technical field [0001] The invention belongs to the technical field of konjac cultivation, and relates to a method for disease-resistant cultivation of konjac under a low-altitude forest. Background technique [0002] Konjac is an herbaceous plant of Araceae. Konjac tuber is the only crop containing a large amount of glucomannan, which has important application value in the field of food and medicine, and konjac polysaccharide is also widely used in military industry, environmental protection, textile printing and dyeing, oil exploration and other fields. However, konjac has weak disease resistance and poor environmental adaptability, which has led to the development of konjac planting areas in low-latitude, middle- and high-altitude mountainous areas. However, due to the increase of drug resistance of pathogenic microorganisms, the current dominant chemical pesticide control method for konjac disease is declining day by day, and it is still very common for konjac productio...
