The root of the lotus root can be eaten raw or cooked, and the lotus seed can also be eaten raw. The lotus seed core can also be used as a medicine. Lotus root can also be processed into glutinous rice powder, which has the functions of appetizing, nourishing and digestion. After the lotus root is introduced from India, it is planted in most parts of China. Here is a brief introduction to the cultivation techniques of lotus root dryland.
I. Dianchi Building Technology
1. Choice of the construction of the pool: When constructing the Dianchi Lake, choose a plot with a flat terrain, a sunny place, and a convenient water conservancy. The soil is required to be loose, fertile, and organic soil-rich clay loam. When building a pool, be careful not to build a pool in a windy area.
2. Building pool technology: The construction of dryland ponds generally adopts a semi-underground method. The shape of the pond can be determined according to the topography and geology of the bottom of the pond. It is generally square and rectangular. The area is between 200 and 350 square meters, and the area of ​​the single pool should not be too large. It is difficult to operate when the building is too large. Before the construction, the soil layer of the bottom of the pond is cleaned to the general level, the contour of the pond is repaired, the bottom of the nautical pool is covered, the plastic film is covered, and then the concrete is compacted and smoothed with 1:1 or 1:2 concrete. Generally not less than 4 cm, the wall is surrounded by hollow bricks around the bottom of the pool, smeared with ash, and the seam between the wall and the repulsive force is treated to prevent water leakage. After the concrete has been condensed, backfill the pool soil cleaned before the pond is built, and pay attention to the waterproofing port around the wall.
Second, balanced fertilization technology
1. High-yield fertilization of dryland lotus roots: According to the characteristics of long-term growth period and fertilizer requirement of lotus roots, the base fertilizer mainly consists of fermented farmyard manure and nitrogen, hydrogen and potassium compound fertilizers, requiring 5000 kg of high-quality farmyard manure and compound fertilizer. 50 kg. The base fertilizer applied before the lotus root planting should be fully mixed with the pool soil. When the lotus root base leaves grow 20 cm, the compound fertilizer is 30-40 kg compound fertilizer.
2. Fertilizer effect of lotus roots in dryland: The lotus root needs a large amount of nitrogen, which should be based on base fertilizer. The quick-acting nitrogen in the top dressing tends to cause burning seedlings and lengthening, which affects the yield; phosphorus and potassium fertilizers should be controlled in combination with the applied fertilizer. The ratio is 1:0.7:0.8 or so.
Third, the selection of cultivation techniques
The lotus root varieties promoted and demonstrated are the white lotus root varieties of the real estate. They are planted before and after the rain, harvested before and after the cold dew, and the yield per mu is 3000 kg. The lotus root is long cylindrical, thick and strong, the skin is white, the top bud is yellow and white, and the leaf bud is yellow-green. The main è—• 4~5 knots, the meat is crisp and tender, the Korean crude fiber is less, raw food, cooked food, can be good, good quality. The flower is pink and less, and it is a local high-yield variety.
Fourth, reasonable planting density
The seedling density of lotus root is generally different depending on the variety, soil fertility, cultivation method and cultivation season. The local white lotus root is generally used in the hole-planting method. Each hole has 2~4 branches per plant, the hole spacing is 1.5~2 meters, and the row spacing is 2.0 meters. The planting amount of acres is 200~250 kg.
Fifth, strengthen management
1. Weeding: Weeding in Putian generally starts from the first fertilization, and ends before the closure of the line. When weeding, the weeds in Dianchi can be lumped into the mud, and the weeding can also be used to adjust the plants. Yellow leaves and dead leaves are also plunged into the mud, but care should be taken to remove the floating leaves before the plants are sealed, so as not to affect photosynthesis.
2. Topdressing: Lotus root topdressing is generally only 1~2 times. The first time is 20~25 days after planting, and there are 1~3 pieces of standing leaves. The topdressing is generally based on organic fertilizer with good rot and heat. Apply compound fertilizer 30~35 kg/mu, it is best not to pursue quick-acting Hefei and non-corrosive chicken manure. The second top dressing before the closure of the line, this time can be appropriate to apply a small amount of fertilizer to promote scarring.
3. Irrigation: According to the growth characteristics and growth stage of lotus root, the irrigation should be carried out according to the principle of shallow, medium and deep.
4. Plant adjustment: The adjustment of lotus root plant is mainly for picking old leaves, folding flower stalks, removing old cockroaches, floating leaves, old leaves, dead leaves and yellow leaves should be removed in time to facilitate ventilation and light transmission. After removal, they can be smashed into the mud. In the early stage, the floating leaves should not be removed too early to avoid reducing photosynthesis. Broken flower stalks can reduce nutrient consumption, and the peduncle should be broken and cannot be removed, so as to avoid the stalk rot caused by the water in the stalk hole.
The above is the lotus root dryland cultivation technology, I hope to help you, want to know more about agricultural planting knowledge, please pay attention to the Hui Nong School!
