Embodiment 1

[0031]In areas with a high degree of mechanization and good irrigation conditions but low rainfall, it is advisable to use full-film double-ridge furrow irrigation cultivation: intensive plowing and fine harrowing, so that the ground is flat and free of straw debris, and then enough base fertilizer is applied, and 4000kg of farmyard manure is applied per mu. , 15 kg of urea and 40 kg of superphosphate. After applying the basal fertilizer, it should be plowed and harrowed to mix the soil and fertilizer, and harrowed to preserve moisture. In mid-April, when the surface soil temperature reaches above 10°C, sow with single-row artificial hole seeder or on-demand device, 2 seeds per hole, sowing depth of 2.5cm, 30,000 seeds per mu, 75cm wide for large ridges, and 35cm wide for small ridges , the height of the ridge is 9cm, the distance between holes is 15cm, and the number of holes per mu is 7400. Use mulch film with a width of 120cm and a thickness of 0.008mm. In the shallow ditch...

Embodiment 2

[0033] In areas with a high degree of mechanization and good irrigation conditions but low rainfall, it is advisable to use full-film double-ridge furrow irrigation cultivation: select 50% promethazol·atrazine, 22% promethachlor and 28% atrazine, add water 30kg, 250ml / mu sprayed on the soil surface, and then harrowed to make it level. After 10-15 days, intensive plowing and fine harrowing, so that the ground is flat and free of straw debris, and then enough base fertilizer was applied. N7kg, superphosphate 50 kg, plowing and harrowing after base fertilizer application to mix soil and fertilizer, harrowing to preserve moisture. In mid-April when the surface soil temperature reaches above 10°C, sow with single-row artificial hole seeder or on-demand device, 3 seeds per hole, sowing depth of 3.0cm, 30,000 seeds per mu, large ridge width 80cm, small ridge width 40cm , the height of the ridge is 12cm, the distance between holes is 17cm, and the number of holes per mu is 8000. Use m...

Embodiment 3

[0035] In areas with a high degree of mechanization and good irrigation conditions but low rainfall, it is advisable to use full-film double-ridge furrow irrigation cultivation: intensive plowing and fine harrowing, so that the ground is flat and free of straw debris, and then enough base fertilizer is applied, and 5000kg of farmyard manure is applied per mu. , fertilizer pure N7kg, P 2 o 5 8kg. After applying the basal fertilizer, it should be plowed and harrowed finely to mix the soil and fertilizer, and harrowed to preserve moisture. In mid-April when the surface soil temperature reaches above 10°C, sow with single-row artificial hole seeder or on-demand device, 2 seeds per hole, sowing depth 3.0cm, 30,000 seeds per mu, 80cm wide for large ridges, 35cm wide for small ridges , the height of the ridge is 12cm, the distance between holes is 16cm, and the number of holes per mu is 7600. Use plastic film with a width of 120cm and a thickness of 0.008mm. In the shallow ditch, ...

Abstract

The invention discloses a feeding-type sorgo cultivating method. The method includes land preparation and fertilizing, seeding at a proper period, cultivating form determining, field management, pest control, harvesting and the like. Actual conditions of land are combined, key technological links like scientific fertilizing, ridging and mulching, precision seeding, irrigation and disease, pest and weed control are quantified according to soil structure, dry farming and high-efficiency farmland water saving technologies are integrated, agricultural machinery and agricultural technology are organically combined, assembled and integrated, a comprehensive supporting system suitable for local sorgo production is formed, and reliable technological support is provided for high yield and stable yield of sorgo.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and relates to a sorghum cultivation method, in particular to a forage type sweet sorghum cultivation method. Background technique [0002] Sweet sorghum (Sorghum bicolor L. Moench), also known as millet, sweet sorghum, sweet stalk and sugar sorghum, is a variety of grain sorghum. Like ordinary sorghum, the yield per unit area can reach 150-500 kg / 667m 2 , but its essence is mainly in sugar-rich plants, and the yield per unit area can reach 4000-8000 kg / 667m 2 stalk. Feed sweet sorghum has great potential for development. Sweet sorghum is rich in nutrients, and its nutrient content is better than that of corn. The sugar content is 2 times higher than that of silage corn. The nitrogen-free extract and crude ash are 64.2% and 81.5% higher than corn, respectively. , fresh and tender stalks, good palatability, livestock love to eat, high biological yield, strong adaptability, is an ex...
