Embodiment 1

[0019] A comprehensive high-yield cultivation technique for sorghum dwarfing and dense planting, comprising the following steps: selecting sorghum variety Zhengdan 958, planting it in Shagou Town, Yishui County, applying 5500kg of pig manure, 15kg of urea, 8kg of potassium chloride, and superphosphate per mu. 25kg, urea slow-release fertilizer 15kg; use subsoiling full-layer fertilization precision sowing machine, subsoil 25 cm, break the plow bottom layer, increase soil water storage capacity, reduce water and fertilizer loss; use the precision sowing machine to apply 6 layers of fertilizer in the whole growth period Around the root system of sorghum, which is beneficial to the 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, planting in wide and narrow rows, the spacing between wide rows is 100-150 cm, narrow The row spacing is 40-50 cm, th...

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

The invention discloses a dwarf culturing and compact planting comprehensive high-yield cultivation technology for sorghum. The technology comprises seed treatment, field planting, field management, weeding and water-fertilizer management: selecting high-quality hybrid sorghum species which is compact planting resistant, dwarf, compact in plant type, has mature straws, a proper maturation period and baldness-free fruits, and is lodging-resistant and disease-resistant, carrying out furrowing for planting according to the furrow width of 120 to 140 cm and the furrow height of about 20 cm, planting the sorghum in a wide-narrow row planting manner according to a spacing between wide rows of 100 to 150 cm and a spacing between narrow rows of 40 to 50 cm as well as a furrow spacing of 35 to 40 cm, planting 3 sorghum seedlings in each furrow, sowing every two treated seeds into each furrow while covering soil which is 1 inches, and treading the soil, wherein 5,700 to 6,700 seedlings are planted in each acre.

Description

technical field [0001] The invention relates to a high-yield cultivation method for sorghum, in particular to a comprehensive high-yield cultivation technique for dwarfed and densely planted sorghum. 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 agricultur...
