The investment in lotus root cultivation can be large or small. Generally, land rent is about 1200 yuan/mu, chemical fertilizers and pesticides are about 600 yuan/mu, lotus root seeds are about 1600 yuan/mu, labor costs for cultivation, harvesting and fertilization are about 1600 yuan/mu, and other costs such as water and electricity are about 200 yuan/mu. The investment in lotus root cultivation is about 5200 yuan/mu. At the same time, loach, yellow eel, etc. can be raised together in lotus root fields.

How much profit is there per mu in lotus root cultivation?

1. Vegetable lotus root: yield per mu is 6600 jin, marketable rate is 80%, wholesale price is 1.6 yuan/jin, that is, 6600*0.8*1.6=8448 yuan.

2. Lotus root seeds: yield per mu is 6600 jin, finished product rate is 80%, wholesale price is 2.6 yuan/jin, that is, 6600*0.8*2.6=13728 yuan.

3. Loach: put in 100 jin/mu in June, harvest 200 jin/mu in November, wholesale price is 18 yuan/jin, that is, 100*18=1800 yuan.

4. Profit: the total income per mu of lotus root is 23976 yuan. Subtracting the cost of 6700 yuan, the net profit is about 17276 yuan.

What conditions are needed for lotus root cultivation?

1. Temperature: lotus root seeds can only germinate above 15°C. During the vigorous growth period, the temperature is required to be 20-30°C, and the water temperature 21-25°C. In the early stage of lotus root formation, the temperature requirement is also relatively high. In the later stage, a relatively large difference between day and night temperatures is required. During the dormant period, it is required to maintain above 5°C. Below 5°C, it is susceptible to freezing.

2. Light: lotus root is a light-loving plant and is not tolerant of shade. During the growth period, sufficient light is required. It is not strict about day length. Sufficient light in the early stage is conducive to the growth of stems and leaves, while sufficient light in the later stage is conducive to flowering, fruiting and the filling of the lotus root itself.

3. Water: during the germination and growth stage of lotus root, a water level of 5-10 cm is appropriate. During the vigorous growth stage, a water level of 30-50 cm is required. Later, as the plant flowers, fruits and forms lotus roots, the water level should gradually become shallower. For overwintering dormancy, it is only necessary to keep the soil fully moist or maintain shallow water.

4. Soil: lotus root grows best in loam and clay loam rich in organic matter. The organic matter content should be at least 1.5%. The soil pH requirement is between 5.6 and 7.5, with 6.5 being the most suitable. It requires equal emphasis on the three elements nitrogen, phosphorus and potassium.

Extension: lotus root cultivation techniques

1. Select good varieties: for planting lotus root, choose shallow-layer lotus root varieties that are uninjured and disease-free, good in variety characteristics, large in individual size, complete in the growing tip, complete in the tail tip, with complete terminal buds and lateral buds, thick and plump lotus root nodes, and early-maturing and high-yielding, and try to make them uniform in size.

2. Fertilize and prepare the field: it is better to choose fertile fields with relatively deep mud layers, convenient drainage and irrigation, and where rice was planted the previous year for planting lotus root. 15 days before planting lotus root, apply 2000-3000 kg of decomposed organic fertilizer, 150 kg of cake fertilizer, 70 kg of superphosphate, and 80 kg of quicklime per mu.

3. Planting time: choose a sunny afternoon and first arrange the lotus root seeds in the field according to the required spacing between plants and rows, then dig trenches by hand according to the size of the lotus root body and plant them. The front end of the planting lotus root should slope downward, and the rear end should be slightly exposed above the soil surface, which is conducive to receiving light and air and promoting germination.

4. Planting method: the depth of entry into the mud should be based on covering the lotus root body and lotus root buds with mud. When planting near the field ridge around the perimeter, note that the lotus root heads should all turn toward the center of the field. When the field is level and the mud is settled, open trenches or ponds for planting.

5. Weeding and leaf removal: about one month after planting lotus root, when the floating leaves gradually wither, remove the withered leaves. Before the rows close, weed in combination with topdressing. When weeding, walk along both sides of the curled leaves. When flower buds appear or flowers bloom, often bend the flower stems but do not break them off.

6. Reasonable topdressing: when there are 3-5 standing leaves, apply 25-30 kg per mu of high-nitrogen and phosphorus compound fertilizer; when standing leaves fill the field, apply 30-35 kg per mu of high-nitrogen and potassium compound fertilizer; when the terminal leaf appears, apply 15-20 kg per mu of high-potassium compound fertilizer or 10-15 kg of pure potassium fertilizer.

7. Adjust the water level: from planting to before germination, irrigate with shallow water of about 5-10 cm to increase soil temperature and help seedling emergence. As standing leaves and branches grow, gradually deepen the water layer to 15-20 cm. During the lotus root formation period and before harvest, it is appropriate to irrigate with shallow water.

8. Straighten the lotus root heads: in June, lotus root vines grow rapidly in all directions, and manual vine management is needed. At noon, dig open the mud and lift the lotus root vines, turn the heads toward blank areas and bury them back into the soil.

9. Mature harvest: when most of the aboveground standing leaves have withered and turned yellow and the lotus roots are fully mature, they can be harvested successively. Lotus root harvesting is divided into green lotus root and withered lotus root. Green lotus root is mostly harvested in August, and withered lotus root is harvested from after the beginning of autumn to March-April of the following year.
