In Yiyang City, ramie seedlings are generally cut with young shoots, divided into two steps: disinfection treatment and cutting. The city's agricultural experts raised relevant precautions on two aspects.
Disinfection: Disinfection includes soil disinfection and shoot disinfection. The disinfectant is usually leached and dipped in a quarter of a potassium permanganate solution (ie, 1 gram of potassium permanganate powder in 40 kg of water). Soil treatment: Before seedlings, use potassium permanganate solution to permeate the seedbed; young shoots: after the young shoots are cut, put them into the prepared potassium permanganate solution for 10 to 15 minutes, and then cut them. After the young shoots are plunged into the seedbed, the seedling bed is drenched with potassium permanganate solution, which can not only make the soil in close contact with the base of the cuttings, but also inhibit the activity of harmful microorganisms. The potassium permanganate solution also promotes hair roots. .
Cutting: the cutting process is, watering - inserting seedlings - watering - inserting bamboo arch - cover film - shading. Before the insertion, the seedbed should be permeable to water. The standard is that the topsoil is 8 to 10 cm wet. There is no “dry heart†in the topsoil with a diameter of more than 3 cm. The soil moisture is high in the soil from April to May, and the temperature is low. Less watering; from June to September, the temperature is high, and often encounter drought and autumn drought, the seedbed should be watered after the insertion.
When cutting, the row spacing is 10 to 12 cm, the plant spacing is 6 to 7 cm, and the young shoots are 2 to 3 cm deep. It is better to insert 8 to 100,000 plants per mu.
The matters that should be paid attention to when cutting the tip are: picking seedlings. From April to May, you can pick up the seedlings all day. From June to September, you must choose morning or before 10 am, and insert the seedlings after 6 pm; do a good job of “five sidesâ€, watering, inserting seedlings, and bending bamboo arches Cover the film with the side curtain, and shade with straw; the young shoots should not be inserted too deeply; the bed of the seedling bed should be 3 to 4 cm wide. After the seedbed is inserted, the soil 2 to 3 cm wide at the edge of the seedbed is dug in the soil. In the ditch, after the cover film, the film is pressed and covered with the seedbed soil.
