Embodiment 1

[0029] Choose to plant in sandy loam dryland with an altitude of 1850m and annual rainfall of 300-350mm, and choose Liaotian No. 5, a medium-early maturing sweet sorghum variety for feeding. The previous crop was wheat, and the land was plowed deeply after the wheat was harvested in mid-July. Rotary tillage and fertilization were performed on October 10, and 3000kg of high-quality farmyard manure was applied per mu (farmyard manure is fully fermented and decomposed human and animal manure, the same below.), "Shikefeng" slow-release fertilizer 50kg (Shandong Shikefeng Chemical Co., Ltd. Co., Ltd., N:P:K content 26-13-7, the same below.), Ridge film covering on October 12, and a 5mm diameter seepage hole was drilled every 50cm in the furrow on October 25. Seeds were sown on April 10 of the following year, and the seeds were treated with 10 mg / L gibberellin for 10 hours. The on-demand hole spacing is 15cm, and 7410 holes are sown per mu, with 2-3 seeds per hole. Harvest for the...

Embodiment 2

[0032] The loess soil dry terraced fields with an altitude of 1580m and an annual rainfall of 450-500mm were selected for planting, and the mid-early maturing sweet sorghum variety Liaotian No. 1 was selected. The previous crop was potatoes, and the land was plowed deeply after harvest in early October. Rotary tillage and fertilization were performed on October 20, 3500kg of high-quality farmyard manure and 55kg of "Shi Kefeng" slow-release fertilizer were applied per mu, and ridges were covered on October 22, and every 80cm was applied in the furrows on November 5. 5mm diameter seepage hole. Seeds were sown on April 20 of the following year, and the seeds were treated with 5 mg / L gibberellin for 12 hours. The on-demand hole spacing is 12cm, and 9260 holes are sown per mu, with 2-3 seeds per hole. Harvest for the first time on August 16, leave stubble 2-5cm, topdress urea 15kg on August 20. The second harvest was carried out on October 22, leaving 5 to 8 cm of stubble.

Embodiment 3

[0035] Choose to plant on the black loam dry-farming mountain platform with an altitude of 2465m and an annual rainfall of 500-550mm, and choose the mid-early maturing sweet sorghum variety Hercules. The previous crop was potatoes, and the land was plowed deeply after harvest in early October. Rotary tillage and fertilization were carried out on October 26, 3500kg of high-quality farmyard manure and 50kg of "Shi Kefeng" slow-release fertilizer were applied per acre. Ridging and film covering were carried out on November 2, and every 80cm was applied in the furrows on November 13. 5mm diameter seepage hole. Seeds were sown on April 22 of the following year, and the seeds were treated with 5 mg / L gibberellin for 12 hours. The on-demand hole spacing is 12cm, and 9260 holes are sown per mu, with 2-3 seeds per hole. Harvest for the first time on August 20, leave stubble 2-5cm, topdress urea 15kg on August 22. The second harvest was carried out on October 28, leaving 5 to 8 cm of...

Abstract

The invention relates to a method for high-yield cultivation of feed sweet sorghum in dry farming mountain land. Dry farming planting technologies such as a dry farming full-membrane double ridge and furrow planting technology, a novel sustained or controlled release fertilizer scientific application technology, fine variety selection and seed treatment, repeated cutting harvesting and a membrane for two years are integrated; the problems of soil depletion, drought and water depletion of the dry farming mountain land, forage grass resource shortage, single variety, low and unstable planting yield of traditional sorghum and poor benefits are solved, and the high and stable yield of feed grass and cultural benefit increase are achieved. The yield of feed sweet sorghum fresh grass per mu (one mu is equal to 0.165 acre) is 7000-9000 kg, and the average yield is increased by over 60% compared with traditional open field planting.

Description

technical field [0001] The invention relates to a method for high-yield cultivation of forage sweet sorghum in dry-farmed mountain areas, which belongs to the category of forage grass planting in dry-farmed areas. Background technique [0002] Sweet sorghum is an annual herbaceous plant belonging to the Poaceae Sorghum genus, which has the advantages of drought resistance, waterlogging tolerance, salt-alkali tolerance, easy cultivation, convenient utilization, and wide adaptability. The yield of fresh grass is 2-3 times that of silage corn, and the sugar content of the straw is high, and the palatability is good, so it is a high-quality forage resource. [0003] In recent years, with the adjustment of the agricultural industry structure, the livestock and grass industry has developed vigorously, especially in the northwest dryland area, the livestock and grass industry has become an important advantageous industry for strengthening farmers and enriching people. However, wit...
