Problems solved by technology

Because konjac is highly susceptible to Erwinia carotovora subsp. Carotovora (Jones) Bersey et al., that is, konjac soft rot, there is currently no effective chemical control, and the frequent large-scale outbreaks of the disease have resulted in a decline in the production of konjac commercial taro even failure
[0003] The existing cultivation method of konjac is to manage the soil moisture first, and then dig deep trenches or deep nests on the soil moisture surface for planting. The fertilizer is placed at the bottom of the trench or the bottom of the nest. The operation procedure is complicated, which is not conducive to drainage, ventilation, light transmission, and fertilizer production. Utilization, not conducive to mining, this method is time-consuming and labor-intensive
Planting with flat soil moisture, poor drainage, poor ventilation and light transmission, and severe disease occurrence
The existing fertilization method of konjac is mainly to apply fertilizer on the bottom of konjac. The base fertilizer is applied to the bottom of the seed before sowing. Improper operation can easily cause seedling burn, and it takes 30-80 days for konjac to emerge from sowing, resulting in nitrogen, potassium and other quick-acting fertilizers. Large loss and low fertilizer utilization efficiency
The middle and late topdressing period of the existing cultivation method is in the third period of konjac head replacement. The konjac root system has grown in large quantities, and the konjac root system is mainly between 5cm and 15cm below the soil surface. At this time, fertilization is easy to damage the konjac root system and leaves, and aggravate the disease. happened
It is easy to damage the konjac bulbs when digging, and it is not conducive to mechanized harvesting
In view of the unfavorable factors such as heavy disease occurrence, low fertilizer utilization rate, and large labor workload in the existing cultivation methods of konjac, the planting area of ​​konjac has not changed much over the years

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a konjac double row strip planting and secondary ridge cultivation method. Background technique [0002] Konjac (Amorphophallus) is a special economic crop, which is rich in soluble hemicellulose glucomannan (Konjac Glucomannan, KGM), which is the seventh nutrient cellulose in the human body, and its processed product konjac powder is widely used It is used in many fields such as food, medicine, petroleum, chemical industry, environmental protection and aerospace. With the rapid rise and development of the health field and the environmental protection field, the global demand for konjac primary processed products has continued to grow in recent years, and the trade of konjac fine powder is generally in short supply. Because konjac is highly susceptible to Erwinia carotovora subsp. Carotovora (Jones) Bersey et al., that is, konjac soft rot, there is currently no eff...
