Seed to be planted
When selecting seeds, the seeds with full grains, glossy black mature seeds should be selected as seeds, dried and stored, and the sowing time should be set in the middle of late September to early October after the stubble of the big autumn crops. It can also be planted in spring and harvested in summer.
site preparation
It is advisable to choose loose, fertile, well-drained sandy soil for planting. After the land is selected, 2,500 kg of decomposed manure or compost is applied per mu in combination with the land preparation as base fertilizer, and then it is fully leveled and leveled, and a high border with a width of 1.3 meters is opened, and drainage ditches are opened around it for sowing.
sowing method
Wang Bu Liu Xing can broadcast on demand or broadcast. On-demand sow on the prepared border, dig holes according to the row spacing of 25 cm × 20 cm, and the depth of the holes is 3 cm to 5 cm. Then according to the amount of seed per mu, mix the seeds with grass soil ash, human and animal manure and water to make seed ash, evenly sprinkle a small amount into each hole, and cover with fine loam after sowing, with a thickness of 1 cm- 2 cm. Drilling, according to the row spacing of 25 cm -30 cm to open shallow grooves, groove depth of about 3 cm. Then, evenly sprinkle the seed ash into the ditch, cover with 1.5 cm-2 cm of fine soil after sowing, and use about 1.5 kg of seeds per mu.
cultivating weeding
When the height of the seedlings is 7 cm-10 cm, the first inter-cultivation and weeding should be carried out. Combine cultivating and weeding, thinning and replenishing seedlings, leaving 4 to 5 strong seedlings per hole; for drilling, thinning the seedlings at a spacing of 15 cm. If there is a lack of plants, the strong seedlings that have been thinned down will be replenished. The second cultivating and weeding was carried out in the second spring from February to March and combined with seedlings. Drill seedlings at a plant spacing of 25 cm. In the future, look at the growth of weeds, and then carry out cultivating and weeding once to keep the soil loose and the field free of weeds.
top dressing
Usually 2-3 times. For the first time, when the height of the seedlings is 7 cm to 10 cm, 1500 kg of thin human and animal manure or 5 kg of urea is applied per mu after cultivating and weeding. After cultivating and weeding in the spring of the second year, 2000 kg of concentrated human and animal manure, 20 kg of superphosphate, or top dressing with 0.2% potassium dihydrogen phosphate 1-2 times per acre is beneficial to increase production.
Harvesting and processing
Seed King Buxing is harvested in April-May of the second year after sowing in autumn. Generally, when most of Wang Buliu Xingzi turn yellow-brown, and a few have turned black, the ground part should be cut off to the ground. Too late and the seeds fall off easily and are difficult to collect. After cutting, put them in a ventilated and dry place for 5 to 7 days. When the seeds are all black, they are dried, threshed, raised to remove impurities, and then dried until they are completely dry. If it is mixed with wheat, it can be harvested with wheat.
