For the cultivation of lotus roots, the top buds are used as the seedlings, and it is necessary to conduct the cultivation of the dry land. The method of raising seedlings in the dry land is to select a deep and fertile dry land and deep plowing in the early spring. Apply 1,500 kilograms of pig manure per acre, 25 kilograms of phosphate fertilizer, and 15 kilograms of potash fertilizer to create a 1.5 meter wide, impossibly limitless length. When the temperature rises to about 10°C, the top buds on the carcass can be cut off. Generally, one can pick 5-8 knots of the top buds, and the cut edges are stained with fresh grass soil. The ash; then, put the seed buds into the soil on the Yangshuo leveling, pouring enough water, covering the top with a rotten, damp straw, and then cover with a film to keep the membrane moist. In early April, when the seedlings unearthed grow 1-2 true leaves and the adventitious roots sprout on the top bud, they can be transplanted and planted in Daejeon. At this time, if the temperature is still low, the time for transplanting and planting can be appropriately postponed, but it should not be too late. After transplanting and planting, due to the small number of seed buds, deep water conservation should be paid attention to. When the seedlings are slightly larger, they can be treated with groundwater in shallow water, apply more nitrogenous fertilizer, strengthen management, and promote growth and development to seize high yields.
Cultivation of lotus roots should be used as a kind of top bud
In many places, lotus roots are cultivated, and all carcasses are commonly used as seeds. The amount per mu is about 300 kg, and the cost is very high. The use of the top buds for the seedlings can save a large number of species, reduce costs, and increase economic efficiency. Therefore, the cultivation of lotus root should be used as the top bud.
