Planting method of shallow lotus root

Shallow lotus root, lotus root and leaves are all short, so they are suitable for cultivation in shallow water with deep 15cm. Planting shallow lotus root is not limited by topography and saves land. Let's take a look at the techniques of planting shallow lotus root.

The technology of planting shallow lotus root

1. Choose excellent lotus root.

Shallow water lotus root should choose excellent varieties suitable for shallow water cultivation as lotus root, such as Hainan Island, Wulian 2 and so on. The best kind of lotus root is the whole lotus root which has more than 4 sections of 3mi and complete son and grandson lotus roots. It is required to plant lotus root stout, buds flourishing, no diseases and insect pests, no damage.

two。 Choose fertile clay loam fields.

The product organs of lotus root are formed in the underground soil. Therefore, the clay loam which can preserve water, rich in organic matter, deep silt layer and fertile clay loam is the most suitable for planting shallow lotus root.

3. Reasonable close planting.

The planting density of lotus root is most closely related to ripening period and yield, and proper close planting can increase yield and early maturity. The general density of precocious varieties is as follows: row spacing is 2.5 meters, hole spacing is about 1 meter.

4. Equal emphasis is placed on base fertilizer and topdressing.

The growth period of lotus root is long and needs a lot of fertilizer. The general principle of fertilization for shallow lotus root is to pay equal attention to base fertilizer and topdressing fertilizer. Generally, animal manure or barnyard manure is applied to 1500,2500 kilograms per mu as base fertilizer. Precocious lotus root is generally applied 1500ml 2000 kg of manure and urine fertilizer per mu. Topdressing is divided into three stages, with emphasis on the initial stage of lotus root.

5. Scientific regulation and control of water level.

The general principle of shallow lotus root water layer management is front shallow, middle deep and rear shallow. During the sprouting period, the water layer should be shallow, and it would be better to have a water layer of 7 cm. During the vigorous growth period, the water layer of stems and leaves should be deeper, and 1215 cm would be better. During the period of lotus root knot, the water layer should be shallow, and it would be better to use 4ml / 7cm.

6. Turn the lotus root tip frequently and weed in time.

During the vigorous growth period of lotus root stems and leaves, lotus roots grow rapidly. When the rolled leaves are about 1 meter away from the edge of the field, in order to prevent the lotus root shoots from crossing the ridge of the field, the lotus root shoots near the ridge of the field are transferred to the field every 2 minutes and 3 days. The lotus root tip is very tender, so the soil and the lotus root tip should be turned together to prevent breaking the lotus root whip, and then press the soil well after turning. It is better to do it at noon when turning the lotus root tip. In the early growth stage of shallow lotus root, there are many weeds, which have a great influence on the growth of lotus root, so weeding should be done in time, and it is better to combine artificial weeding with chemical weeding.

7. Harvest in time.

After the lotus root terminating leaf appears, the leaf back of the terminating leaf is reddish, and when the edge of the basal standing leaf begins to wither and yellow, the lotus root has fully matured. The lotus root can be dug up and listed at this time.
