Recently, a vegetable farmer friend consulted in the back of the school. How can lotus roots be cultivated before they can be listed in advance and sell for a good price? Here are some of the key points for high-yield planting of lotus roots for your reference.
First, the selection of good varieties
Of course, lotus root varieties should be selected, such as good seed, large size, and complete tail tips. Shallow varieties with early maturity and high yield are suitable.
Second, fertilizing the whole field
The muddy layer should be selected, and the fertile rice fields are better, and the paddy fields have been planted in the previous year. About fifteen days before planting lotus roots, two thousand to three thousand kilograms of organic fertilizer were applied, seventy kilograms of superphosphate, eighty kilograms of quicklime, and one hundred and fifty kilograms of thick cake.
Third, planting germination
First, pile up the seeds, the height can be about one meter, and then use the dry straw to spread around. Usually remember to always sprinkle water on the seedlings, maintain a certain humidity and temperature, when the top buds grow out, you can plant them, and the planting time is best sunny morning.
Fourth, planting density
The early maturity cultivation mode generally requires a higher density of the drainage, the amount of the used grain is 250 to 300 kg, the row spacing is 0.8×1.8 m, and the per mu requires 300-400.
Fifth, planting methods
The lotus roots between the rows and rows should be arranged in a plum blossom shape, and the bud heads of the seedlings on the four sides of the lotus field are oriented inward.
Six, arch cover film
Cover the membrane in time after planting. Use a bamboo frame with a length of 3 meters and a width of 3 centimeters to make an arch of about 300 pieces. The arch is 2.2 meters wide and the arch is 40 cm high.
7. Early management of the field
This period is mainly to promote the formation and growth of floating leaves. To manage the water, it is better to keep the water layer 5-10 cm, keeping the soil in a muddy state. When the temperature is high on a sunny day, it is necessary to ventilate in time to prevent burns on the lotus leaf. After the middle and late April, when the temperature is stable at around 20 °C and the arch shed is full of lotus leaves, the film can be unscrewed, the water in the field can be poured to 10-15 cm, and the manure is 1000 kg and the urea is 15 kg. .
Eight, middle and late management of the field
Generally, the grass is manually pulled in the middle and late May. After the grass is pulled, in order to evenly distribute the lotus root in the field, the growth direction of the lotus whip should be adjusted in time, and the lotus whip should be prevented from growing into the field. In this period, 20 kg of compound fertilizer and 10 kg of urea should be applied.
Nine, do a good job in disease prevention and control
The common disease of lotus root is mainly lotus leaf soft rot. If it happens, keep the water clean at all times, and remember to remove the diseased leaves in time, and then use 70% methyl thiophanate 800-1000 times liquid every 10 days. Spray once.
Ten, harvested
When the lotus root grows three quarters, it can be harvested in batches, and the harvest time can be about twenty days earlier than conventional cultivation.
In summary, it is to let the lotus leaves mention the key points of the morning market. You can refer to the study by yourself. Here, you should also remind you that the specific practical technology should be decided according to the variety you planted, the local environmental climate, and the usual management habits!
