Embodiment 1

[0019] A high-yield sorghum dense planting cultivation method, comprising the following steps: select sorghum variety Zhengdan 958, plant in Shagou Town, Yishui County, apply pig manure 5500kg, urea 15kg, potassium chloride 8kg, superphosphate 25kg, urea Slow-release fertilizer 15kg; use a subsoiling full-layer fertilization precision sowing machine, subsoil 25 cm, break the bottom layer of the plow, increase soil water storage capacity, and reduce water and fertilizer loss; use the precision sowing machine to apply 6 layers of fertilizer in the whole growth period to the sorghum root system Surroundings, which is conducive to absorption during the whole growth period and reduces leaching; field planting is: planting in a row, the width of the row is 120-140 cm, and the height of the row is about 20 cm. 40-50 cm, the distance between the holes is 35-40 cm, 3 plants per hole, sow the treated seeds double in the ditch, cover the soil while sowing, cover the soil 1 inch and make i...

Embodiment 2

[0023] Select the sorghum variety Tiantai No. 10 and plant it in Shagou Town, Yishui County. Apply 5,500kg of pig manure, 15kg of urea, 8kg of potassium chloride, 25kg of superphosphate, and 15kg of urea slow-release fertilizer per mu; use deep pine for full-layer fertilization The precision sowing machine, loosening 25 cm deep, breaks the plow bottom layer, increases the water storage capacity of the soil, and reduces the loss of water and fertilizer; through the precision sowing machine, apply 6 layers of fertilizer in the whole growth period to the sorghum root system, which is conducive to the absorption of the whole growth period and reduces leaching ; Field planting is: planting in a row, the width of the row is 120-140 cm, the height of the row is about 20 cm, the width of the row is planted, the row spacing of the wide row is 100-150 cm, the row spacing of the narrow row is 40-50 cm, and the spacing of the holes is 35-40 cm. cm, 3 plants per hole, sow the treated seeds ...

Embodiment 3

[0027] The sorghum variety Danyu 86 was selected and planted in Shagou Town, Yishui County. 5500kg of pig manure, 15kg of urea, 8kg of potassium chloride, 25kg of superphosphate, and 15kg of urea slow-release fertilizer were applied per mu of land; Sowing machine, deep loosening 25 cm, breaking the plow bottom layer, increasing soil water storage capacity, reducing water and fertilizer loss; using a precision sowing machine, apply 6 layers of fertilizers during the whole growth period around the sorghum root system, which is conducive to absorption during the whole growth period and reduces leaching; The field planting method is: planting in a row, the width of the row is 120-140 cm, the height of the row is about 20 cm, the width of the row is planted, the row spacing of the wide row is 100-150 cm, the row spacing of the narrow row is 40-50 cm, and the spacing of the holes is 35-40 cm , 3 plants per hole, sow the treated seeds per point in the ditch, cover the soil while sowin...

Abstract

A high-yield sorghum close planting cultivation method includes the steps of seed treatment, field planting, field management, weeding and water and fertilizer management, wherein an excellent hybrid sorghum variety which is resistant to close planting, dwarf, compact in plant type, green in straw, proper in mature period, free of cluster baldness and resistant to falling, diseases and pests is selected, trenches are formed for planting, the width of each trench ranges from 120 cm to 140 cm, the height of each trench is about 20 cm, seeds are planted in wide lines and narrow lines alternately, the line distance between the wide lines ranges from 100 cm to 150 cm, the line distance between the narrow lines ranges from 40 cm to 50 cm, the hole distance ranges from 35 cm to 40 cm, each hole is provided with three seeds, the treated seeds are sown in the trenches in the mode that each point is provided with two seeds, the seeds are covered with soil of one cun when sown, the soil is compacted with feet, and the number of seedlings reserved in each mu ranges from 5700 to 6700.

Description

technical field [0001] The invention relates to a high-yield cultivation method of sorghum, in particular to a high-yield sorghum close-planting cultivation method. Background technique [0002] my country is a populous country, and sorghum is one of the three major food crops. Sorghum production occupies a very important position in my country's agricultural production and national economy. The development of sorghum production has great practical significance for increasing farmers' income, ensuring national food security and even economic security. Although the total annual production of sorghum in my country has developed rapidly, the total annual production of sorghum is insufficient, and there is still a large gap with the market demand for sorghum in my country, and a large amount of sorghum needs to be imported every year. Affected by the lack of per capita agricultural land resources in my country and the adjustment of agricultural planting structure, it is diffic...
