Technical aspects of taro cultivation
Potatohead is a potato crop, produced in hot and humid marshlands such as ours and india. Warm and drought-prone areas of sandy sandy sandy soil require a high temperature and humidity, with a long-term temperature of more than 20 degrees, a good growth of the tubers at 27-30 degrees, a more obscenity, and short-day sunlight can facilitate the formation of the tubers. The main technical measures to grow taro are:
I. Equipping the ground and applying base fat
Taro requires the selection of fields with deep, fertile, lax and easy drainage, with no seeding of taro in the first year. Fifty kilograms of raw lime per acre were disinfected during ploughing. The whole area is grown in two rows, with a width of 1 metre wide, a ditch wide of rice, a ditch deep, and a whole area covered with base fat, per acre farmers who are fatter than 1500-2000 kg or decomposed chicken dung of 750 kg, bio-organic fertilizers of 50-100 kg are mixed in the middle of the plant and potassium sulfate compound fat 25 kg is applied between the two。
Ii. Early planting in due course, rational planting
The seeding of taro is long-term in excess of 13-15 degrees, and my county generally began planting around mid-march. In the run-up to winter and after new year's day, a seedling of culinary membrane cover was requested, and after the long-term sprouts, the month was chosen to grow in a clear weather to ensure high prices by mid-august. Potato should be grown with no insect rotting, sprouts full of sprouts and a well-structured tubing, with two to three days of seeding. Plants are grown at distances, seeded according to the size of the potato, covered with dust from fire or grass cover, followed by water showers to keep the soil humid and spray the whole field with pre-breed herbicides。
Iii. Implementation of membrane-covered cultivation techniques
When the taro is planted, it is covered with a transparent membrane of 7-8 pounds, which requires that the compartment be flat, the mud is broken and the membrane is pressed along it. When covering the membrane, care should be taken to detect the growth of the lumber, the membrane should be broken in time, the membrane should be 20 cm wide, and the soil should be used for pressure and the seedlings should be replaced in time, so that the cover can last until the end of july, when heavy fertilization is applied。
Iv. Rational fertilization, scientific plumbing
1. Reasonable fertilization. Subject to the application of base fattening, an appropriate application of thin biogas or dung may be made in the preceding period, until the size of the taro is increased by 1,000 kg per acre of farm weight, 50 kg of peanut shells, 15 kg of potassium sulfate, 50 kg of bio-organism, 2 kg of magnesium magnesium fat, and 30-45 days of platinum on the side of the block. In the middle of the summer in july, 25 kg of potassium sulphate compound fertilizer per acre and potassium sulphate. Fifteen kilograms are mixed evenly on the surface, with the shallow soil covered and fertilized, and weeds around the fields shall be removed prior to fertilization. No more fertilization after august. Potassium dihydrochloride, etc., can be sprayed in the rapid expansion of tacos in combination with pest control, which can contribute to the expansion and production of tacos。
Scientific piped water. Prior to the application of the fertilizing film, the roof should be kept wet, the water should be removed from the ditches in the rain, the weather should be dry and the gutters should be humid. During peak periods of growth, the trenches are to maintain a 1 inch of water to humid bottom and stop watering 10 days before harvest。
V. Timely showering of condensers and hysteria
1, multi-purpose beers and antimony. When the taro is 5-6 leafs, it's about 45 centimetres tall, 5 kilos per zone and multi-effects. A mixture of 150 grams of rinsing, followed by a multi-acting gill 150 grams of venom or leaf spraying in 20 days. Use can increase or decrease depending on the strength of the plant. In the clear sky, 15 grams of more than 40 kilos of water, 80-100 gravitational leaves, 80 centimetres tall, and more than 5 leaves, based on closed lines。
2. Excision of larvae. It began to happen when the taro grew to 7-8. In order to reduce nutrient dispersion and consumption, the ointment mast swells, and when the tat leaves one leaf, it is carefully cut off from its growth point with a knife or shovel, and care not to cut it. You have to keep the taro。
Vi. Making full use of the taro-head field for seeding
Tacos are grown early and harvested by the end of august, making full use of the tacos for a set of maize, and by the end of november for a set of sweets or snow beans. Four harvests of fields。
Vii. Pest management
Physico-biological control should be used as a priority, based on agricultural control, and efficient, low-toxic and low-residual pesticides should be selected and not banned in order to ensure the quality of taro。
The main diseases are:
