How to grow Lipu taro? Where is the origin of Lipu taro?

1. Land selection and soil preparation: select fertile and loose plots with convenient irrigation and drainage and strong fertilizer and water conservation as planting areas, and then dig deep into the soil to make border. 2. Sufficient base fertilizer: 2,500kg of decomposed organic fertilizer is applied per mu, and the ratio of N, P and K fertilizer is 1.2: 1.2. 3. Selection of seed block: Choose taro with no wound, no plant diseases and insect pests and complete bud tip as seed taro. 4. Sun-drying to accelerate germination: the seed taro is sun-dried to accelerate germination, and can be planted when the bud length reaches 1cm. 5. Sowing date: The first half of March is the suitable sowing date. After sowing, topdressing seedling fertilizer should be done in time, and soil cultivation, weeding and plastic film mulching should be done well.

First, how to plant Lipu taro

1, land selection and land preparation

(1) Choose fertile and loose fields with convenient irrigation and drainage, strong fertilizer and water conservation, and no taro, and peanuts and sweet potatoes are suitable for the previous crop.

(2) Continuous cropping of taro is not suitable for 1 year, which will lead to a decrease in yield. If the previous crop is Gramineae, the yield reduction can even reach 30%.

(3) Before sowing, soil preparation should be done well, and turning over more than 40 cm can promote bulb growth and increase yield.

2. Apply sufficient base fertilizer

(1) Apply 2,500 kilograms of decomposed organic fertilizer per mu, or 6,000 kilograms of soil miscellaneous fertilizer rich in organic matter per mu, and then turn over the soil to mix the fertilizers evenly.

(2) NPK fertilizer should be applied at the ratio of 1.2: 1: 2. Generally,1-1.2kg of pure nitrogen, 0.8-0.84kg of phosphorus pentoxide and1.00kg of bulbs should be applied.

(3) The dosage ratio of chemical fertilizer per mu is 35 kg of diammonium phosphate+50 kg of compound fertilizer+75 kg of ammonium bicarbonate+bone meal 100 kg.

(4) In mid-July, phosphorus and potassium fertilizers can also be applied, such as potassium sulfate, calcium superphosphate, diammonium phosphate, ammonium bicarbonate and other fertilizers.

3. Select the seed block

(1) According to the research, the yield of taro with the same size will be reduced by more than 6% compared with the whole taro without cutting the stem, so the taro with medium size should be planted, which is rich in nutrition and can accelerate the plant growth.

(2) Bulbs should be spherical, weighing about 50g, and there should be no wounds, mildew, pests and diseases on them, and the tip of the terminal bud should remain intact.

(3) When the seed taro in the middle of taro is selected as seed, the seed taro hairs and lateral buds should be removed to avoid sprouting lateral buds.

4. Dry seeds and accelerate germination.

(1) Before sowing 15-20 days, the seed taro was treated with sun drying and wet sand to accelerate germination.

(2) The stored taro should be put in the sun for 1-2 days, and then put in the germination bed alone, and the temperature should be controlled at 18-20℃.

(3) When the bud length reaches about 1 cm, start sowing, which can ensure the taro to germinate neatly.

5. Sowing time

(1) If the seeds are sown too early after the final frost, problems such as rotten seeds and weak seedlings will easily occur. If sowing is too late, it is easy to cause seedling burning.

(2) If you want to prevent taro from freezing after emergence, you can sow it in advance, which can also prolong its growth period and achieve the effect of increasing production.

(3) When the temperature reaches 13- 15℃, the suitable planting time is the first half of March. If you plant it with plastic film, you can sow it 30 days in advance.

6. Tian Tuan management

(1) Rational fertilization

(1) seedling stage: topdressing 1 time to raise seedling fertilizer; The budding trees and bulbs need topdressing for 2-3 times in the early and middle stages of growth, and nitrogen, phosphorus and potassium fertilizer should be applied together.

② Late stage of seedling stage: control the amount of topdressing to prevent taro from being greedy for green and maturing late. The ratio of N, P and K is 15: 15: 15. Generally, 40-50 kilograms of compound fertilizer can be applied per mu, and calcium superphosphate 100- 150 kilograms can be used as base fertilizer.

(3) After full sowing: soil cultivation, weeding and plastic film mulching should be done well. The ratio of nitrogen, phosphorus and potassium is 16: 10:20. Generally, 75-65,438+000 kg compound fertilizer can be applied after topdressing, and the fertilizer can be watered.

(2) Scientific water management

(1) Early stage: low temperature and slow growth rate. Just keep the soil moist at this time, and watering is not allowed at seedling stage, so as not to affect rooting and emergence.

② Middle and late stage: high temperature and fast growth rate. Water should be used properly in summer to prevent drought (water should not be used at noon in hot weather to avoid leaf withering), and drainage should be paid attention to in rainy season. Before fertilizing and uncovering the film, the surface of the carriage must be watered to keep it moist.

③ Peak growth period: there should be at least 3 cm shallow water layer at the bottom of the ditch, and the watering amount should be controlled at 20 days before harvesting, and the watering should be stopped at 10 day before harvesting.

(3) intertillage and soil cultivation

① Bulb growth too fast will affect the quality. Soil cultivation can inhibit the terminal buds of taro and sun taro, reduce nutrient consumption and promote bulb growth.

(2) Before closing the ridge, combine intertillage weeding for 2-3 times, every 15-20 days 1 time, and cover the soil for 5-7cm each time.

(4) Artificial weeding

(1) After sowing and watering, spray herbicides, such as dur, prometryne, Hennessy water, etc. Spray 20 ml of herbicide every 60 kg per mu.

(1) or spray 150g acetochlor water per mu, and combine with scarification and fertilization for artificial weeding in the growth period.

2. Where is the origin of Lipu taro?

1, Lipu taro is mainly produced in Lipu City, Guangxi (native to tropical swamp areas such as India, Malaysia and Hainan). ). It is a major local traditional product, especially in Xinping, Dumo, Qingshan and Xiuren.

2. Lipu taro has good shade tolerance, so it doesn't need to provide too much light when planting, but it needs to provide enough water, otherwise the leaves will die after encountering high temperature and dry weather.

3. Lipu taro is similar in shape to olives. Its skin is rough and has a special smell after cutting. It has a betel nut pattern inside, so it's also called? Areca taro? .

4. Lipu taro is rich in nutrition, containing starch, crude protein, vitamins, calcium, inorganic salts and other ingredients, which can be used to process taro powder and dozens of foods.
