The lotus root belt has now become one of the most dazzling food on the table, so what are the planting techniques of the lotus root belt? The following is my carefully organized for you to take a look at the technology of planting lotus root belt.
Lotus root planting technology
① scientific selection of the root field: lotus root planting using greenhouses, lotus root field should be selected water, drainage and irrigation is convenient, fertile soil, soil layer deep and loose back to the sunny plots, such as the choice of viscous soil that retains water and fertilizer, planting results will be better.
② reasonable building shed: build shed, generally in the lotus root field after the selection, at the end of February can start, direction to the north-south as well, span of about 5 to 7 meters, the main high in 1.6 to 1.8 meters, between the bow and the bow of about 0.4 meters, the conventional shed film 8 meters wide, the upper part of the film with film line compaction, surrounded by the film with the film compression paper compaction.
③ land fertilization: field roots need more fertilizer, but because of its weak root growth capacity, it is appropriate to use deep tillage operations, generally 45 square per hectare of soil fertilizer, followed by irrigation and harrowing composting, in the next 1 day before the seed combined with the application of 225 kg of urea or ammonium carbonate 750 kg, 750 kg of phosphate fertilizer, potash 225 kg; or a one-time application of nitrogen, phosphorus, potassium composite fertilizer 750 kg with the application of bio-potassium fertilizer 15 kg.
④ choose a good seed: seed lotus root more shallow into the soil, shallow water resistance, good quality, high yield of early maturity varieties, such as Jiangsu 8135, Zhejiang Kexian 1, Hubei June report. Greenhouse lotus root planted in early March, usually in early June market, 1 month earlier than the conventional planting field, 1 month before the morning market. Before planting from the seed field to choose the seed root, choose the root body thick, neat, thin section for the seed root to the whole root or pro-root and child root to stay in the seed, to the size of the grading were planted, with digging, with the selection, with the planting. Planting density depends on the cultivation conditions. General row spacing of 2 meters, hole spacing of 1.5 meters, 3 branches per hole, the amount of seed per hectare is about 2250 kg. Planting method Mostly used large lotus root and small lotus root combination of three-forked method of planting, 10 to 15 cm deep, in order not to float, do not shake as the principle. The heads of the roots correspond to each other, surrounded by 1.5 meters apart, and the side rows of root heads are all inward.
⑤ Lotus root field management: After planting the seed lotus root, it should be immediately flooded with about 5 centimeters of water. Afterwards, keep 3 to 6 centimeters of shallow water to promote the soil temperature to rise in order to facilitate germination. From the occurrence of lotus leaves to the lotus root, the water layer should be gradually deepened to 15 centimeters, keep 5 centimeters of water layer before the lotus root, to prevent early flooding of the standing leaves, resulting in a reduction in yield. In the field lotus root reproductive period, the general fertilizer 2 times. The first fertilizer in 2 ~ 3 standing leaves, 300 kg of urea per hectare, 600 kg of phosphate, potash 300 kg; or 750 kg of compound fertilizer; the second in 4 ~ 5 standing leaves, 375 kg of urea per hectare, 600 kg of phosphate, 375 kg of potash or 900 kg of compound fertilizer. Lotus root field pests are mainly aphids, ground maggots; diseases are mostly leaf spot disease, brown streak disease and rot disease is heavy. In the prevention of insects, more than the use of phoxim fine soil treatment, in the control of aphids, more than the use of trichlorfon, metribuzin plus 10 times the lime water spray control, and can be added to the appropriate amount of regulators, such as harvest treasure, green wind 95 and so on. At the same time, before the lotus leaves are full of ponds, when there are more weeds, you can plow the grass a few times, and step the weeds into the mud. Generally, when there are 4 to 5 pieces of standing leaves, after the lotus whip draws, it is necessary to often extend the whip to the edge of the field in the afternoon to turn to the field, the field is too dense to turn to the sparse whip, and will be turned to the new slightly buried in the soil. When the standing leaves are full of leaves, the floating leaves are shaded, and when there is not enough sunlight, the floating leaves can be removed, or a small number of standing leaves can be removed from the upper part of the water surface.
⑥ Harvesting: the harvesting of the greenhouse planting of lotus root, more in the early to mid-June harvesting market, harvesting the old lotus root in late July.
The technical points of lotus root planting
(1) ZiLian lotus root. Hubei sub-lotus varieties are mainly Xianglian series and Ganlian series, the general implementation of a planting, two or three years of cultivation, in the second and third year of harvesting lotus root belt.
The sub-lotus cultivation, the first year of planting density of 100 to 120 / mu, to the second and third year, the field seed root density of 1600 / mu or more, the density is too large. For the sub-lotus cultivation, the role of harvesting lotus root strips is mainly to thin seedlings.
The first year: mid-March to mid-late April planting, July to mid-October harvesting of sub-lotus; the second and third years: May to mid-June harvesting of lotus root strips, July to mid-October harvesting of sub-lotus.
The sub-lotus root belt is a by-product of sub-lotus cultivation, so the production is generally not special management, just in accordance with the sub-lotus cultivation management measures for normal management.
(2) lotus root ribbons. General lotus varieties can be used for lotus root belt cultivation, such as E lotus one, E lotus five, E lotus six, E lotus seven, Wushu plant two. Lotus root lotus root belt cultivation mode are mainly:
? Lotus root with commercial lotus root? Cultivation mode: mid-late March ~ mid-late April planting, with the amount of seed is generally 300 ~ 400kg / mu or more, mid-late May ~ the end of July staged harvesting of lotus root strips. After the lotus root stops harvesting, strengthen the fertilizer and water management, late September to the next year, mid to late March or mid to late April to harvest commercial lotus root.
? Lotus root for planting lotus root? Cultivation mode: mid-late March ~ mid-late April planting, the amount of seed is generally 300 ~ 400kg / mu or more, mid-late June ~ early September staged harvesting of lotus root strips. After the harvesting of lotus root strips stops, lotus root for seed is produced. The yield of lotus root can reach 300-400kg/mu. Under this model, the lotus root grown in the fall is small and poorly commercialized, but it is more suitable to be used as seed root in the following year. The yield of seed root can reach 1000～1250kg/mu. Some of the seed roots propagated in this way are dug up and used as seed roots, while others are not dug up and are left on the field to be used as seed roots for the following year and harvested as root strips. This mode of cultivation in the paddy field, the lotus root can be harvested until the middle and end of August; in the fish pond or pond cultivation, can be harvested until the middle of September.
How to grow lotus rootSelection of lotus root seedlings:
Pay attention to the lotus root tail where there will be some of the lotus root holes. Also cultivate the growth of new root buds, in addition to the growth of some root growth in the place of buds, such seedlings can be used for planting.
Adjust the direction of planting:
Just remember to put the tail of the root seedling upward, and the bud end of the root seedling is tilted downward to ensure that the head and tail ends have a leaky part, which will not lead to water entry.
Digging the mud to open the pit:
Dig the mud away from the planting site and dig a suitable pit, not too deep and not too shallow. It needs to be determined according to the growth and size of the root seedlings, mainly to expose the root tails outside the mud, but also to protect the root buds. In short to ensure that it will not be submerged when adding water is almost the same.
Mud planting:
Cover almost the entire root with mud that is not too wet in the same place. If the root shoots are too short, you can also bury them in the soil, so that their growth will not be affected. However, it is important to keep the perforated end of the root out of the soil. The first is not anxious to water, let the sun warm a few days, until the buried root seedlings of the soil slowly cracked and then wet it.
Watering:
When the soil is a little dry, add some water to moisten the soil. At this time, the root's ability to absorb water is particularly good. After it grows almost in one piece with the silt, you can add a small amount of fertilizer, out of chemical fertilizer can also be natural fertilizer.
Add water to flood the mud to ensure moisture:
When the root seedlings grow to a certain point, you can add a suitable amount of water, so that the water flooded over the surface of the mud. But still can't submerge the root tail part, still have to let it cradle above the water surface.
