Konjak interplanting crop-rotation cultivation method

Abstract

The invention provides a konjak interplanting crop-rotation cultivation method, which comprises the steps that ridges and belts are made in a selected land plot according to width of 4.5-5 chi (chi is a unit of length and one chi is equal to 1 / 3 meter) to form a reserved line; konjak is planted on one side of the reserved line, high-stalk crops such as sunflowers, corns and sesame are planted in the other side of the reserved line and then wheat, rape or leguminous crops are planted in belts in which the konjak is planted; and when the konjak is harvested, konjak with big bulbs with weight above 450g and damaged konjak are sold as commodities, konjak with small bulbs with weight below 350g and konjak tubers are used as seed konjak and are locally and nearby planted in belts in which other crops (which have been harvested) are planted on the other side of the reserved lines. By adopting a local and nearby crop-rotation interplanting cultivation technique, the disease incidence rate of konjak can be decreased, the labor intensity is reduced and the good harvest of both konjak and other crops is realized.

Description

technical field [0001] The invention relates to the field of crop planting, in particular to a konjac interplanting cultivation method. Background technique [0002] Konjac is a high-efficiency crop that has an obvious role in helping farmers get rid of poverty and become rich. It has become a preferred income-increasing project in suitable areas. At present, the development of konjac has expanded from a single food application to the fields of medicine, chemical industry, textile, printing and dyeing, and petroleum. It has wide uses, great development potential, and good market prospects. It is called a sunrise industry in the new century. [0003] However, with the promotion of artificial cultivation techniques and large-scale planting, the original growth environment has changed. The konjac species has degenerated, the ability to resist diseases has weakened, and the yield has decreased. The trend of increasing year by year has directly affected the enthusiasm of farmers...

Problems solved by technology

[0004] Production practice shows that after three years of continuous planting of konjac in the same plot, farmers will have to replace it with a new plot for replanting. In addition, konjac is a crop with significant regional characteristics, which has strict requirements on soil quality, resulting in the choice of plots. "Limited". In addition, changing land and stubble will increase labor intensity and cost in disguise, and it is easy to cause damage to planted taro during transportation, which increases the risk of pests and diseases
