'121-mode' planting method of konjak ridge compartments

Abstract

The invention provides a '121-mode' planting method of konjak ridge compartments. The method concretely comprises the steps of (1) selecting konjak with the weight of 100-300g as seed konjak; (2) disinfecting the seed konjak and the soil before sowing seeds; (3) ridge compartment manufacture: manufacturing the ridge compartments with the widths of 90-100cm and the heights of 25-30cm, wherein the widths of operating grooves are 20-25 cm; arranging the ridge compartments along the north and south direction; (4) carrying out intercropping planting according to the standard mode that a row of corns and two rows of konjak are planted in each ridge compartment; planting a row of corns besides each ridge compartment and two rows of konjak on the ridge compartment, wherein the plant spacing of the corns is 30-35cm, the plant spacing of the konjak is 35-40cm, the row spacing between the corns and the konjak is 30-35cm, and the row spacing among the konjak is 35-40cm; (5) harvesting: after the leaves at the overground part of the konjak are withered, and stems are soft and have lodging phenomenon for a week, harvesting by digging. The konjak planting mode is innovated, so that the sunshade rate of the konjak can be controlled to be 50-60%, and the konjak and the corns are guaranteed to reach the effects of coordination and mutual benefit.

Description

technical field [0001] The invention relates to a konjac planting method, which realizes disease prevention and high yield, standardized planting and reduces pests and diseases by taking measures such as gathering soil to form ridges, adjusting ridge direction, interplanting, and reserving operation ditch. Background technique [0002] Konjac is a perennial herbaceous plant of Araceae Konjac. Its unique physical and chemical properties make it have a wide range of application and development value. It has a good market prospect and is called a sunrise industry in the new century. [0003] At present, with the expansion of artificial large-scale planting area, unprecedented problems have also appeared in konjac production. Konjac species degeneration, yield reduction, and disease resistance are weakened, and the occurrence and damage of diseases are increasing year by year. The disease rate is between 21- 40%. In addition, konjac is a crop with significant regional character...

AI Technical Summary

Problems solved by technology

[0006] Three-foot ridge box planting, such as figure 1 As shown, the width L1 of the ridge is about 100 cm, and a row of corn A (30 cm between plants) and a row of konjac B (40 cm between plants) are planted in each ridge, and the distance between corn A and konjac B is about 40 cm; With 4400 plants, 3300 plants of konjac can be planted. Although the density of konjac is guaranteed, the shading rate of corn (57-63%) is a little bit higher, and it is not worthwhile to plant only one row of konjac in the area.

[0007] Four-foot ridge box planting, such as figure 2 As shown, the width L2 of the ridge is about 120 cm, and two rows of corn A (30 cm between plants) and one row of konjac B (40 cm between plants) are planted in each ridge. The distance between corn and konjac is about 40 cm; 1,400 konjac plants can be planted. The density of konjac is not enough, the yield is low, and the shading rate of corn is too large (over 70%), the main body of konjac planting is not prominent, and the economic efficiency is poor.

There are about 1,200 corn plants per mu, and 2,800 konjac plants can be planted. Although the density of konjac is guaranteed, the shading rate of corn (30-40%) is too small, the sun is too strong, and the incidence of konjac diseases is relatively high (15-20%). Affect the overall yield of konjac
