Seeding time
The best time to sow konjac is in mid-April. Specifically, according to the meteorological information, sowing before the rain or after the rain according to the soil moisture can be selected.
Fertilization of the land
Choose plots with deep soil layers, high organic matter content, no stagnant water, and no heavy stubble. Before sowing, the plot is organized, the field is cleared of stones and weeds, and the drainage ditches on all sides are opened. The bottom fertilizer is applied at one time, and the organic fertilizer is 1-2 tons per mu.
Sowing points
Shallow furrows and high ridges. The depth of the ditch for taro breeding is about 5 cm, and the depth of the ditch for commercial taro breeding is about 10 cm, so as to ensure that the top bud of konjac is basically at a parallel level with the plot. High ridges, the ridge height of taro breeding is about 15 cm, and the ridge height of commercial taro breeding is about 20 cm. The shallow furrow and high ridge can not only ensure the growth of konjac roots in the loose and breathable soil layer, but also avoid the adverse effects of drought and rainfall on root growth.
Wide ridges and narrow species. The distance between konjac and the edge of the ridge is more than 20 cm, and the distance between the konjac and the edge of the ridge is more than 30 cm. Wide ridges and narrow planting can not only ensure the rapid growth of konjac roots to the surrounding areas, but also reduce the competition between intercropping crops and konjac for water and fertilizer.
The rows are wide and dense. The row spacing for commercial taro breeding is 40-50 cm and the plant spacing is 30-40 cm, and the row spacing for taro breeding is 20-30 cm and the plant spacing is 10-20 cm. When konjac is planted in two or more rows, the taro should be placed in a staggered position. The row width and dense plant density can not only ensure the ventilation and light transmission of konjac field, but also facilitate the field operation in the later stage.
Cover the lid on the top. Corn interplanting shading should be a corn variety with tall stalks and large leaves, such as Anke 136. The planting time varies depending on the altitude, but is generally from late April to early May. Use straw, chaff, etc. to cover the ridge surface, covering the thickness of 5-10 cm. Ground cover can play a role in weed control, moisture preservation and ground temperature reduction.
