The name of thistle is Huanghuayuan, a legume herb. In recent years, the growing area of ​​alfalfa in Yangzhong City has brought about a large demand for high-quality seeds. Its breeding techniques are described below.
In Daejeon's direct seeding and sowing, we choose to plant plots with fertile soil, convenient drainage and irrigation, and strong water retention and fertility conservation. It is best to plant legumes without the previous crop. Before the planting, 400 to 600 kg of organic fertilizer is applied per acre, deep-opening 18 to 25 cm to make a ditch, and 1.5 to 2 meters wide and 10 to 15 cm high. From mid-October to early November sowing, 4 to 5 kilograms of pods per acre. The seeds are dried for 3 to 4 hours and soaked in 50% chlorothalonil wettable powder 500 times for 24 hours. After the soaking, the seeds can not be sown in time after raining. The seeds can be kept in the cool place for 1 to 2 days. The thickness should not exceed 10 cm. The sprinkler should be kept moist every day and sowed after sunny weather. Dry seed sowing in continuous rainy weather. Drilling, broadcast amplitude of 10 to 15 centimeters, spacing 25 to 35 centimeters, after the broadcast is practical and practical. There are more dew-seeds and can be used to cover seeds. After sowing, the sensation was watered every morning and evening. Watering was stopped after Qimiao.
After the field management, the weeds were promptly weeded, the grass weeds were controlled with high-efficiency flupirtine, and the broad-leaved weeds were manually removed. Qi seedlings were sprayed with 2% urea solution and potassium dihydrogen phosphate solution was sprayed during the growth. The diseases and pests of Valeriana are rare. When the temperature is high, there are aphids and sclerotinia diseases, which can be controlled by imidacloprid and procymidone.
Seedlings are transplanted and planted to breed strong seedlings from late September to mid-October. Seed 1 ~ 1.5 kg per acre. The selection of sandy soil land with medium soil fertility, deeper soil, and good ventilation requires planting with strong soil moisture and the former cannot be a leguminous crop. The ratio of seedbed to field is 1:20. Seed processing is the same as the live broadcast method. Do the sowing, the width of 1.5 to 2 meters. Open shallow trench drill, groove width 10 cm, spacing 20 to 25 cm, the seeds mixed with bone meal (1 kg dried seeds with 0.5 kg of bone meal) or appropriate amount of ash after planting, width 3 to 5 cm. After the broadcast, it is practical to pour the manure water or compound fertilizer solution, cover the fine soil (preferably grass ash), and cover the thickness no more than 3 cm. Watering in time to keep the seedbed moist. When seedling blight occurs, it is treated with carbendazim and sodium propionate. Ten to fifteen days after emergence, rhizobia were not formed and a small amount of nitrogen fertilizer was applied.
Planting seedling age 40 to 50 days, seedling height 10 to 15 centimeters when planting, fertile soil land planted 2000 acres per acre, poor fertility plots planted 3000 points per acre. Each hole is planted with 3 to 5 strains, and soil mixed with appropriate amount of phosphate fertilizer, bone powder or plant ash is used as base fertilizer in the hole. 10 to 15 days after planting, 20 kg of calcium magnesium phosphate fertilizer and 100 kg of plant ash were applied to the root of the seedlings at a distance of 10 cm per acre, combined with cultivating cover soil. Field management is the same as Daejeon's live broadcast.
Timely harvest of barnyardgrass flowering and fruiting for up to 2 months, the seeds gradually mature from the base of the plant, and the pods easily fall off. Harvested when the fruit color is 30% cyan, 30% yellow, 40% black. The harvest was too late and the fruit had fallen off and could be removed with a broom. Select the sunny morning dew when the plants were cut roots, drying 2 to 3 days after shaking plants so that the pods fall off, Yang net dried after the collection for sale.
