Summer planting blue root cultivation technology

Banlangen, also known as Daqing root, is rooted and used as medicine. Clinically used to treat hepatitis, influenza, sore throat embolism. In recent years, due to the needs of "SARS" and people's lives, products have become more and more beautiful and in short supply. The cultivation points are as follows:

First, choose and prepare land. Choose fertile sandy loam with flat terrain, drainage and irrigation conditions. After the wheat harvest, the cultivator deep-turned about 30 cm in time, fine smashing, leveling, for 1.5-2.5 m rake, while the Mushi organic fertilizer 2000-3000 kg, 50 kg of ammonium bicarbonate, calcium superphosphate 40 kg or 100 kg of plant ash.

Second, timely sowing. Summer sowing is carried out before and after the "mountain seed". The sooner the better. Seeds are soaked in warm water at 30-40°C for 3 hours before sowing. Remove and dry the seeds and mix them with ash or fine sand. Can be broadcast or broadcast. Drilling is conducted at a spacing of 20-25 cm. The machine is used to open the ditch, and the ditch is about 3 cm deep. Then the seeds are spread evenly in the ditch. The soil thickness is about 1.5 cm. The seed amount is about 2 kg per mu. After sowing, 7 - Emergence in 10 days.

Third, field management. When the seedlings are 6-8 cm high, they can be seedlings. When the seedling height 10 cm can be set seedlings, the general spacing is 6-9 cm. Dingling, weeding and weeding. Drought watered in time to keep the soil moist. According to the condition of the seedlings, timely collection of leaves. After each leaf collection, 5-8 kg of ammonium sulfate or 10 kg of urea can be applied per acre to facilitate multiple new leaves. If the leaves are not harvested, less fertilizer can be applied. During the rainy season, clean drainage should be taken care of to prevent the accumulation of stagnant water.

Fourth, pest and disease control. To prevent and control downy mildew, it is necessary to clear the fields in time after harvest, and burn the diseased plants in a concentrated manner; conduct rotation to eliminate water in a timely manner; use 1:1:100 Bordeaux mixture or 65% zein zinc WP 500 times in the initial stage of disease. Spray control, spray once every 7 days, even spray 2-3 times. The method for controlling sclerotinia is to conduct crop rotation, apply phosphorus and potassium fertilizers earlier, increase disease resistance, reduce humidity, and prevent waterlogging. Use sulfur compounds in the roots of plants. The method of controlling root rot is to spray with 50% carbendazim 100 times solution or 70% thiophanate-methyl 1000 times solution at the early stage of disease, while pulling out the diseased plant or irrigating 1:1:100 times Bordeaux mixture. , And promptly rule out the accumulation of water in the field to prevent the occurrence and spread of diseases. The control of Pieris rapae is controlled by spraying 90% trichlorfon 800 times in larval instars. Control locusts with 40% Dimethoate 800 times or 1000 times spray.

V. Harvesting. Usually planed in late October. Choose sunny days, cut off the leaves, dried, and serve as medicinal black leaves. When digging, you must dig deep, dig out the roots along the roots of the earth with a fork, wash away the dirt, and dry it before entering the market.
