Hercules is a kind of hybrid hybrid sorghum for feeding. It belongs to the annual feeding plant. In 2004, it was approved by the National Forage Variety Approval Committee for the first feeding sorghum variety, registration number 292. The strength of Hercules is salt-tolerant, thin, sturdy, and high in sugar content. Let's study the cultivation techniques of Hercules for hybrid hybrid sorghum. 1 Biological characteristics The strong sorghum sorghum stalk is 200-500 cm high and the base stalk is 2~2.5 cm. It has the characteristics of large leaves, strong tillering force and fast regeneration after castration. Leaves 7 to 12, about 1 m long, about 8 cm wide; ligules dura mater; leaf sheath glabrous or white powder. The inflorescences are tight or slightly tight, 20 to 40 cm long and 5 to 15 cm wide. In 2015, Guizhou became one of the national corn reduction areas. After two years of reduction, the corn planting area in 2016 decreased by 707,000 mu compared with 2014, a decrease of 6%. Therefore, considering the development of forage, we must also consider the principle of non-food replacement that does not compete with food and food, and encourage the cultivation of forage crops on marginal non-cultivated land. Hercules sweet sorghum adapts to a wide area, has strong drought resistance, resistance to thinness, sputum tolerance, salt and alkali resistance, strong tillering power, high biological yield, good palatability, etc., compared with forage corn, soil and fertility requirements are not high The planting cost is low, and the biological yield is 0.5 to 1 times higher than that of the forage corn. Feeding the livestock can produce better economic benefits and is suitable for the transformation of the structural adjustment of the planting industry in Guizhou. 2 Cultivation techniques 2.1 Soil selection Sweet sorghum has low requirements on soil and can be produced on all types of soils. Among them, loam rich in organic matter and deep soil is the best. Sweet sorghum seedlings have poor top soil ability, which is easy to cause lack of seedlings and ridges. Fine land preparation before sowing is of great significance to ensure the whole seedling. Deep tillage is the basic element of soil cultivation and the basis for feeding crop nutrition. 2.2 planting varieties Screened by the introduction test, Hercules Sweet Sorghum is relatively suitable in Daozhen County. 2.3 Cultivation techniques 2.3.1 Sowing time Daozhen County is suitable for planting in April. Spring is premature, the ground temperature is low, the emergence is slow, and it is easy to rot, affecting the emergence rate. Spring is too late to use light, heat, humidity and other conditions. A suitable sowing period is beneficial to increase the yield per unit area of ​​forage. 2.3.2 Planting methods 1) On-demand Line spacing 80 cm × plant spacing 30 cm, 4 to 5 seeds per litter, 3 seedlings per litter, 8,000-8500 plants per mu. 2) Striping Ditching with a line spacing of 80 cm, 11,000 plants per mu is more suitable, too low yield is low, too dense and easy to fall to reduce production. 2.3.3 Seeding rate The sweet sorghum has a weight of 20 to 25 grams. Considering the effects of germination rate, emergence rate and pests and diseases in the field, the general seeding rate is 1.5 to 2 kg/mu. 3 Field management 3.1 early stage The focus is to cultivate strong seedlings. When the seedlings have 3 to 4 leaves, the seedlings are carried out, and when the leaves are 5, the seedlings can be fixed. Combine the seedlings to go to the tillers early, and promote the single seedlings. 3.2 mid term The key point is that the plant grows robustly. At this time, the growth is the strongest, and the demand for nutrients is the largest. The fertilizer should be increased. Generally, urea is applied at 10 kg/mu. In case of drought, it should be irrigated in time. 3.3 late The key point in the late growth stage is to enhance the vitality of the root system, and to protect the leaves by roots. At this time, the water should be poured in time to carry out foliar fertilization, and potassium dihydrogen phosphate, superphosphate, and high-yield can be sprayed. 3.4 top dressing In the large trumpet period of sweet sorghum, combined with rainfall, 10 to 20 kg/mu of ammonium nitrate or 10 to 15 kg/mu of urea. 4 Harvest and utilization Forage sweet sorghum is mainly used for green feeding, silage, and green hay. Different cutting periods can be selected according to the purpose of use. The sweet sorghum seedlings contain hydrocyanic acid, which is easy to be poisoned; the hydrocyanic acid content decreases at the late stage of jointing to the heading stage, the plant biological yield also reaches the maximum, the crude fiber content is small, the leaves are tender and juicy, the nutritional value is rich, and the palatability is good; Near maturity, the content of crude fiber is large, the external part of the straw is gradually hard, the moisture content is small, the palatability is decreased, and it can be used as silage. 1) Green feeding Timely castration is conducive to feeding sorghum tillers. When the plant is 1 to 1.5 meters, the hydrocyanic acid content should be castrated in time to promote tillering. The height of the stubble is guaranteed to be 1 or 2 knots on the ground to facilitate plant regeneration. The number of cuttings depends on the sowing time, the local natural conditions, the biological characteristics of the variety, etc. The timely castration is conducive to the improvement of the feeding value of the feed sweet sorghum. It is recommended to harvest the mites in most areas of Daozhen County. 2) Silage Sweet sorghum silage converts carbohydrates into lactic acid under anaerobic conditions, thereby inhibiting the growth of harmful microorganisms, allowing silage materials to be preserved and maintaining nutritional value. It is best as the late harvest of silage sorghum. Silage can preserve the nutrients in the sweet sorghum for a long time and can regulate the imbalance of feed supply.
