Planting technology sharing: lotus root planting technology!

In rural areas, there are many rice fields and pits and ponds that have been abandoned for a long time because they can not be used effectively. If they can be properly reformed to plant lotus roots in lotus roots ponds, considerable benefits will be obtained!

1. Transformation of lotus root pond

1. Leveling in order to ensure that the water level of the lotus root pond is consistent and the lotus root grows evenly, the bottom of the lotus root pond needs to be leveled.

2. if the water leakage of the lotus root pond is serious or the local water resources are scarce, an impervious film should be laid at the bottom of the lotus root pond to prevent water leakage. It is best to use the lotus root pond special impervious membrane for laying, after the completion of the backfill high-quality soil 30 cm. Due to the high cost of laying impervious film, the impervious film should not be laid as much as possible under the condition of good water retention performance of lotus root pond.

2. Selection of lotus root species

1. According to the water depth, the lotus root is divided into shallow water lotus root and deep water lotus root. Shallow water lotus root can be selected under 50 cm water depth (such as 3735 lotus root, pearl lotus root, giant lotus root, Huaqi lotus root, etc.). Deep water lotus root (such as snow lotus root, floating flower lotus root, Fenghe No. 1 lotus root, hybrid large white lotus root, etc.), water depth 150 cm 220 cm need to choose super deep water lotus root (such as Weishan lake white lotus root, etc.).

2. According to the taste, lotus root can be divided into waxy lotus root (high starch content) and crispy lotus root (low starch content). The south likes waxy lotus root such as 3735 lotus root and giant lotus root. North likes crisp lotus root should plant snow lotus root, white lotus root and other crisp lotus roots.

3. Planting techniques of lotus root

The main results are as follows: 1. The density of lotus root needs 400 kg to 500 jin per mu, and the planting amount should be increased appropriately if water gun is used. The planting density can be planned according to the seed size of lotus root. If it is a special lotus root species of 1.5 kilograms or so, the plant spacing and row spacing are 2.5 meters and 1.1 meters respectively.

2. Before applying fertilizer and planting, 2 square meters of rotten chicken manure were applied per mu, 80kg / mu of potassium sulfate compound fertilizer was applied when standing up leaves, 80kg / mu of potassium sulfate compound fertilizer was applied at full flowering stage, and 100kg / mu of potassium sulfate was applied at lotus canopy expansion period. Attention should be paid to the application of urea, potassium chloride compound fertilizer and high nitrogen compound fertilizer, otherwise the yield of lotus root will be seriously affected.

3. Manage to maintain proper water level and strictly prevent water shortage or waterlogging; after standing leaves of lotus root, 1-3 grass carp can be put in per mu according to duckweed and water grass.

Fourth, the planting benefit of lotus root

1. The cost rent is 400yuan / mu, lotus root seed 800yuan / mu, fertilizer 600yuan / mu, artificial 300yuan / mu, other 200yuan / mu, totaling 2300 yuan / mu.

2. The yield of lotus root can be harvested after entering the Mid-Autumn Festival, which can last until May Day the following year. Under the condition of shallow water planting and proper management, the lotus root can be harvested per mu of 8000 to 10000 jin, of which the main lotus root yield is 5000 to 6000 jin. The mining cost of water gun is 0.3 yuan / jin per mu and that of hydraulic engineering is 0.5 yuan / jin and 2500-3000 yuan per mu respectively.

3. The price of benefit lotus root varies from north to south and from east to west, and the wholesale price ranges from 0.8 yuan to 2.2 yuan per jin. If the wholesale price can reach 1.5 yuan / jin, the lotus root can be sold for 7500,000 yuan per mu, excluding the planting cost of 2300 yuan and the excavation cost of 3000 yuan per mu, the net profit can be 23003700 yuan per mu.
