The bitter buckwheat is also known as the bitter vegetable, the festival lotus root, the little bitter wheat dish, the bitter leaf seedling, the bitter wormwood, the yellow rat grass, the bitter diced cabbage, and has the effect of cooling and detoxifying and eliminating phlegm.
First, the environmental requirements
The bitter leeks have strong adaptability to the environment, and are resistant to heat and cold. The suitable temperature for growth is 15°C-20°C, and they grow well in moist, nutritious sandy loam soils. Adaptable to light, but easy to aging under strong light.
Second, soil preparation
Sandy loam with good irrigation conditions was selected as the cultivation field. After the harvest of the previous crop, the land was deeply turned. Combine 1500-2000 kg of organic manure and 15-20 kg of urea into the base fertilizer per acre. Fine soil preparation, making a width of about 1.5 meters flat, ready to broadcast.
Third, choose the seedbed
Seedbed should choose a place with high topography, low groundwater level and good irrigation and drainage. The best choice is to choose a plot or raw ground where the same kind of vegetables has not been cultivated. If old seedbeds are used, bed soil should be disinfected, or basement seedlings can also be used.
Fourth, seed processing
Before sowing, soak in seeds with warm water at 55°C for 10-15 minutes, or use 50% thiram wettable powder or 65% zein zinc wettable powder. The dosage is 0.3% of the seed amount.
Fifth, planting seedlings
Buckwheat generally takes the form of seed propagation. Sowing can be done in mid-April. The open field sowing can be carried out in a well-distributed bowl with a 25-30 cm line spacing and a ditch depth of 2-3 cm. The seeds are evenly spread into the ditch and the soil is sown after sowing. If the soil is dry, it can be watered in an appropriate amount, covered with straw after being watered, and it can also be covered with mulch to prevent soil compaction. Such as early spring cultivation, the temperature is low, can be used in the greenhouse for seedling transplanting. Water immediately after planting, shade on sunny days, maintain a high temperature to promote slow seedlings. 3-5 days to slow seedlings.
Sixth, fertilizer and water management
1. After emergence or easing seedlings, proper control of water should be conducted to prevent seedlings from becoming prolonged. When the seedling height is 5-6 cm, cultivating and weeding are performed to prevent weeds from inhibiting seedling growth.
2. After weeding, combined with watering, apply 20 kg of available nitrogen fertilizer per acre to promote seedling development.
3 bitter leeks should be properly dense planting, seedlings generally do not seedlings. Such as seedling density can be appropriate sparse seedlings, 2-3 strains of a cluster, spacing 4-6 cm, seedling height 4-6 cm when the timely tillage weeding. Every time you cut it, you must top-dress fertilizer and water.
Sodium citrate test tube with blue cap Sodium citrate acts as an anticoagulant mainly by chelating calcium ions in blood samples. The ratio of anticoagulant to blood was 1:9. The whole blood or plasma samples were prepared. After collection, the samples were immediately reversed and mixed for 5-8 times. After centrifugation, the upper plasma was taken for use, which was suitable for coagulation test, PT, APTT, and coagulation factor tests.
