The planting technique of Wang Buliuxing

Wang Buliu is the dry seed of Caryophyllaceae plant, such as Brassica campestris and Brassica campestris. It has the functions of promoting blood circulation, relieving pain and giving birth to milk. It is mostly wild in wasteland and roadside. It is resistant to drought and barren, and it can also grow with wheat. The adaptability is extremely strong, and the yield per mu is stable between 150kg and 300kg. Let's take a look at the planting technology of Wang Buliuxing.

The growth habit of Wang Buliuxing

Wang Buliuxing likes warm climate, does not have strict requirements on soil, and avoids flooding. If planted in low-lying waterlogged areas, the roots rot easily in the rainy season, the aboveground parts gradually turn yellow, □ dies, and even no grain is harvested in serious cases. In areas that are too dry, the plants grow short and the yield is very low. Born in fields, roadsides and wastelands, most of them are in wheat fields. China is distributed in Heilongjiang, Jilin, Liaoning, Hebei, Henan, Shanxi, Shandong, Jiangsu, Anhui, Zhejiang, Jiangxi, Hunan, Hubei, Shaanxi, Gansu, *, Yunnan, Sichuan and other places.

The sowing technique of Wang Buliuxing

1. Seed selection for sowing: Wang Buliuxing usually propagates with seeds. Full, glossy and black mature seeds should be selected and stored after drying. The sowing time should be set from mid-late September to early October after the stubble of autumn crops. Sowing in the middle of April in the northern region can also be sown in spring and summer harvest.

2. Land selection and land preparation: Wang Buliuxing should choose sandy loam and clay loam with gentle slope and good drainage. After land selection, it should be combined with autumn ploughing and apply mature base fertilizer of 3000 to 4000 kg per mu. If calcium superphosphate is applied at the same time, the seed yield can be increased.

3. Sowing method: Wang can sow on demand or strip without leaving rows, sowing on the whole border surface, digging holes according to the row-plant spacing of 25 × 20 cm, and the hole depth is 3-5 cm. Then, according to the seed amount of 1 kg per mu, the seeds were mixed with plant ash, human and animal manure, and made into seed ash. Each hole was evenly sprinkled with 1 pinch, and then covered with fine fertile soil, 1 cm thick. Strip sowing opened a shallow trench with a row spacing of 25cm and a depth of about 3cm, and then spread the seed ash evenly into the ditch. After sowing, the fine soil was covered by 1.5cm, and the amount of seed used per mu was about 1.5 kg.

The planting technique of Wang Buliuxing

1. Intertillage weeding: when the king does not leave the seedling height of 7cm or 10cm, carry out the first intertillage weeding, it is appropriate to loosen the soil shallowly to avoid root damage, and weeds are pulled out by hand. Combined with weeding by ploughing, seedling intercropping and seedling replenishment were carried out, and 5 strong seedlings were left in each hole. Strip sowing seedlings according to the plant spacing of 15 cm. If there are missing plants, use the strong seedlings from time to time to replenish the seedlings. The second intertillage weeding was carried out in combination with fixed seedlings in February and March of the second year.

2. Topdressing at the right time: Wang Buliuxing is usually topdressing for 2 or 3 times. For the first time, 1500 kg of human and animal feces or 5 kg of urea were applied per mu after weeding in the middle tillage when the seedling height was 7cm. After intermediate ploughing and weeding in the spring of the second year, 2000 kg of human and animal manure water and 20 kg of calcium superphosphate were applied per mu, or 0.2% potassium dihydrogen phosphate was used to topdressing the root twice, which was beneficial to increase the yield.

3. Pest control: Wang Buliu should increase the application of phosphorus and potassium fertilizer, or spray 0.2% potassium dihydrogen phosphate solution on the leaf surface to enhance the disease resistance of the plant. At the initial stage of the disease, 65% Dysen zinc 500 × 600 times, or 50% carbendazim 800 × 1000 times, or 1% 1% 100 Bordeaux solution were sprayed once every 7 days and 3 times in a row. The heart borer harms the fruit with larvae and is sprayed with 1000 times of 90% trichlorfon or 1000 times of dichlorvos.

4. Harvest and processing: Wang does not leave the line to be harvested from April to May in the second year after autumn sowing. Generally, when most of the seeds become yellowish brown and a few have turned black, the above ground part should be cut off in time. If the harvest is too late, the seeds are easy to fall off and difficult to collect. After cutting back, put it in a ventilated and dry place and ripen for 5-7 days. When the seeds are all blackened, dry, thresh, remove impurities, and then dry to become a commodity. If mixed with wheat, it can be harvested with wheat.
