1, planting time: lotus root planting time and area and temperature are related, generally suitable for lotus root planting the best time is March, April every year. The most suitable temperature for the growth of lotus root is about twenty to thirty degrees, so the earliest planting of lotus root temperature must also reach more than fifteen degrees, otherwise the chances of survival are not high. The temperature difference between the south and the north of China is a little big, so the south is usually planted in February and March lotus root, and the north will be a little later in April and May to start planting.

2, planting method:

(1) selection: lotus root in the selection of seeds should pay attention to observe, in the lotus root of the lower part of the growth of new shoots, and in the shoots of the side will grow some new roots, such seedlings can be taken directly to the planting. Secondly, we will choose at least three or more intact lotus roots, and try to choose the ones that look bigger and without disease, and the new shoots look more vigorous. The bigger the lotus seed, the better, so that the newly developed young roots will also be better when the time comes.

(2) Sowing: Lotus root seeds do not try to place too long, usually selected immediately after planting, before planting the first root seed treatment, the root seed with a targeted agent to be stirred after the planting, so that you can prevent a lot of growth in advance in the process of the environment caused by the disease. When planting, try to plant as deep as possible, so that the roots will grow big and good. Sowing density according to the size of the pond you choose to estimate, the general development of the lotus root is relatively fast and long open area is also relatively large, so it is generally every thirty to fifty centimeters planted a plant, and in the near future it will be full of the entire pond, densely populated.

(3) field management: after about a month of planting, the lotus leaves and flowers in the pond will slowly grow out, at this time we have to remove some leaves and flower buds, to avoid them absorbing a large amount of nutrients, hindering the growth of lotus root. In the growth process of lotus root, grow five or six lotus leaves when we have to carry out a fertilization, mainly to prove that it is alive, and then wait until the pond lotus leaves are basically full to fertilize once, which means that a lot of small tender lotus root has appeared, the need for adequate nutrients, the last fertilization is in the pond has been slow to no new leaves grow, which also means that the lotus root is slowly growing, so it needs a lot of nutrients, and it needs a lot of nutrients, and it needs a lot of nutrients. Slowly grow, so need a lot of nutrients to maintain their growth. Finally, the water level in the pond can not be too deep or too shallow, generally normal control in ten to fifteen centimeters.

(4) Harvesting: When the color of the back of the terminating leaf of the lotus root is a little red, it means that the lotus root has matured and can be harvested. Because the lotus root grows deeper, and you don't know how it grows, so you have to dig along its termination leaf slowly to its original leaf direction, so that the dug out lotus root is the most complete.
