The soil preparation is a dicotyledonous plant belonging to the genus Euphorbiaceae. The root system of ramie grows strongly. It is a conical root system with thick straight roots and 3-7 larger lateral roots. The straight root is 2-4 meters deep and the lateral roots are flat and up to 1.5-2 meters. Ramie has a strong ability to adapt to the soil, drought tolerance, alkali resistance, and generally the soil can grow as long as it is well drained, but fertile soil is better, and the requirements for the former crop are not strict.
Seeds should be seeded and seeded before sowing so as to increase seed germination rate. Seeding should be sowed in early and late April when the average temperature reaches 12-15°C. If mulching is used under conditions, the growth period can be increased by about 15 days. Sowing generally uses artificial seed, row spacing 80-100 cm, 2-3 tablets per hole, according to different fertility, 800-1200 per acre stay, seed sowing depth of about 6 cm, timely cover soil after sowing, suppression.
Field management check seedlings, make-up seedlings: timely detection of castor seedlings after emergence, check seedlings, make up the seedlings, found that seedlings need to timely transplant seedlings. Transplanting ramie at the seedling stage is easier to survive, and transplanting time is preferably within 3 leaves at the seedling stage. Dingling is carried out on 3-4 leaves, leaving one plant per hole when seedlings are set. Cultivating, weeding, and cultivating soil: Ramie is a warm-grained crop with a deep root system, so cultivating the soil as early as possible to increase ground temperature. The cultivator usually takes 3-4 times from emergence to flowering, and the depth is about 10-15 cm. Fertilization: Applying enough base fertilizer is the key to ensure high yield of ramie. The ramie needs a large amount of fertilizer. According to the measurement, 100 kg of castor bean must consume 6.9 kg of pure nitrogen, 1.6 kg of phosphorus pentoxide and 5.8 kg of potassium oxide. The base fertilizer must be applied adequately. Generally, 15 kg of urea or 10 kg of diammonium and 7 kg of potassium sulfate are applied. The first top-dressing stage was in the bud stage of the first main ear, and generally applied 50 kg of ammonium bicarbonate. The second top dressing was applied in the fourth ear with 40 kg of ammonium bicarbonate. The whole technique: for the first time, three stout branches are left as primary branches after the main stem is budded, and the branches below the five leaves are all removed. The first time in the first 40 days of the first frost, all the growth points were destroyed.
80% of the harvested fruit on the standard ear is yellowish-brown and can be harvested. The reclaimed pod should be promptly dried and threshed. The moisture can be bagged and sold when the moisture content drops below 9%.
