[0029] 2. In the present invention, by using the accurate proportion of farmyard manure and phoxim, the farmyard manure provides sufficient nutrients for the planting soil of konjac to meet the nutritional demand of konjac growth. At the same time, the addition of phoxim can be infiltrated into the soil together with the farmyard manure, which can effectively prevent and control underground pests, inhibit the breeding and spread of harmful pathogens in the soil, reduce the risk of diseases and insect pests in konjac, create a relatively safe and stable soil ecological environment for the growth of konjac, and promote the healthy growth and development of konjac.

[0030] 3. In the present invention, by accurately controlling the konjak planting depth, suitable planting depth can make the konjak seed taro be in a relatively stable temperature and humidity environment after sowing, and the soil of suitable depth can absorb and store heat faster, for providing a warm environment for the germination of the seed taro, effectively improving the survival rate of the konjak seed taro planting.

[0031] 4. By drying and dehydrating the konjac seeds and treating their wounds, a dense layer of protective tissue can be formed at the wounds of the konjac seeds. After sowing, this can effectively prevent pathogens in the soil from entering the seeds through the wounds, thereby reducing the chance of the seeds becoming diseased after planting and laying the foundation for the healthy growth of konjac. This allows the konjac seeds to better adapt to the soil environment, temperature changes and humidity changes after planting, thereby increasing the survival rate and initial growth vitality of the seeds.

[0032] 5. Through accurate control of the planting plants, as well as accurate control of the amount of fertilizer and topdressing, the roots of konjac can absorb the nutrients brought by the fertilizer in a timely and appropriate manner, avoiding the growth of konjac due to uneven fertilization, and effectively improving the growth rate of konjac. By sowing corn near konjac planting, intercropping corn planting can form a complex ecosystem in the field, and the roots of corn can be used to consolidate the soil. At the same time, the taller corn plants can play a role in wind blocking and shading, which can stabilize and prevent konjac planting from lodging, avoid konjac plants from being exposed to the sun for a long time, causing soil dehydration, and improve the survival rate of konjac planting. According to different varieties of konjac and corresponding to the growth habits of different varieties of konjac, different sowing areas are selected for konjac, and suitable konjac varieties are sown at suitable altitudes and geographical environments, which effectively improves the survival rate of konjac sowing, thereby improving the economic benefits of konjac planting.
