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.

The present invention provides a method for intercropping and cultivating konjak by a northern high-stem plant, which is characterized by comprising the following steps: A, intercropping and cultivating the konjak in a forest land or a corn field, applying 1 to 2 tons of decomposed organic fertilizer for each mu, then spreading 100 jins of calcined lime over each mu to sterilize the soil, and turning over and flattening the field; B, sterilizing konjak seeds; C, adopting ridge culture and oblique culture to intercrop 3 to 5 rows of konjak at a konjak ridge height of 20 to 30 centimeters, a ridge surface width of 20 to 25 centimeters and a forest belt of 3 to 5 meters, or intercropping 1 to 2 rows of konjak in a corn row, and inclining the seeds for 45 degrees facing the sun; and D, performing grading seeding, wherein the planting density uses 6 to 8 times diameter of the konjak seed as a row space and 4 to 5 times diameter of the konjak seed as a plant space, and covers 15 to 20 centimeters of soil. By adopting the technical scheme of the present invention, the increment amplitude of intercropping the konjak in the forest land is 3 to 7 times that of the primary seeds, the per mu yield reaches more than 1,500 kilograms, the utilization efficiency of the forest land is improved by over 20 percent, the economic benefit in each mu is increased by more than 2,000 yuan, and the utilization path of the forest land is effectively broadened.

The invention relates to a rivier giantarum rhizome pit planting method, and belongs to the technical field of crop cultivation. The method comprises the specific steps that 1, seeds are selected, wherein 100-250 g of rivier giantarum rhizomes with no scab or rot are selected as seed rivier giantarum rhizomes; 2, storage is carried out, wherein the seed rivier giantarum rhizomes are stored at the indoor temperature in a heat preservation mode after being dried in the sun; 3, grooves are dug, wherein land parcel outer edges are selected, and grooves are dug along the land edges; 4, backfilling is carried out, wherein the grooves are backfilled with straw and fine soil, and strip-shaped planting belts are formed through accumulation; 5, seeding is carried out, wherein seeding is carried out in mid-to-late April next year. By the adoption of the rivier giantarum rhizome pit planting method, the soil organic matter can be increased, the soil quality can be improved, the soil water permeability and breathability are improved, the development space is expanded, the problems that the rivier giantarum rhizomes have harsh requirements for land parcels and a few of appropriate planting areas exist are solved, and the purpose of controlling and relieving diseases and improving the yield of the rivier giantarum rhizomes is achieved. Chemical fertilizer and pesticide can be replaced, or the usage amount of chemical fertilizer and pesticide can be reduced, high yield and stable yield of the rivier giantarum rhizomes are achieved, and it is ensured that the product is environmentally friendly and safe in quality.
