Three-dimensional one-cultivation-two-harvest high-yield brewing glutinous sorghum cultivation method

Abstract

The invention discloses a three-dimensional one-cultivation-two-harvest high-yield brewing glutinous sorghum cultivation method, which includes sorghum variety choosing, soil preparation, fertilization, seedling growing, transplantation, disease and insect pest control, regenerated sorghum germination promotion, fertilization, disease and insect pest control and other steps. By choosing a glutinous sorghum variety suitable for producing Maotai-flavor liquor, adopting plastic hole plate seedling growing method to grow seedlings, transplanting sorghum seedlings according to double triangles, applying seedling promoter and jointing fertilizer early and adopting other methods, the yield of sorghum per mu is increased by more than 200 kilograms on average and the income per mu is increased by nearly RMB 1000 yuan, so the method can bring remarkable economic benefit in comparison with conventional sorghum cultivation methods.

Description

technical field [0001] The invention belongs to crop cultivation techniques, in particular to a cultivation method for wine-making waxy sorghum. Background technique [0002] Sorghum belongs to the Gramineae family and belongs to the genus Sorghum. Also known as sorghum, milo, etc., it is a high-yielding crop known as a "hardcore crop" by the masses. It is widely cultivated in China, especially in Northeast China. Sorghum grains are used for food, wine making (currently, it is mainly used for brewing sauce-flavored liquor) or making caramel. The stalks of sorghum used for sugar can be made into syrup or eaten raw; the stalks can be squeezed to boil sugar, and farmers call it "sweet sorghum straw"; the ears of sorghum used for brooms can be used to make brooms; The highly toxic hydrocyanic acid must be dried in the shade or dried in the sun before it can be used as feed. [0003] The planting of sorghum can be divided into spring cropping and autumn cropping. The sowing pe...

[0005] For example: patent document [Application No.] CN201310106704.2 discloses a "cultivation method of wine-making organic sorghum", which includes the following steps: a. Seed treatment: select plump non-transgenic sorghum seeds to dry, and dry them at 30°C to 30°C before sowing. Soak seeds in salt water at 35°C for 12-24 hours, salt: water mass ratio = 1-2: 100; b, sowing: according to organic nutrient soil: alluvial river bed soil = 1: 1-1.5, mix well to make nutrient soil, and put it into a seedling tray , sow the treated seeds in step a into the nutrient soil and place them in the shed. After sowing, control the temperature in the shed to 10°C-35°C and the humidity to 80-90%; wait for the seeds to germinate and grow 2-3 leaves before starting Seedling hardening; c, transplanting: apply base fertilizer to the transplanting land before transplanting, and start transplanting when the seedlings reach 5 to 6 leaves, and adopt the wide and narrow row planting mode to transplant; the wide row is 80 to 83 cm wide, and the narrow row is wide 50-53cm, plant-to-plant distance 15-17cm, check the field and replenish seedlings 3-5 days after planting; when the seedlings grow to 9-10 leaves, topdress joint fertilizer; use nicotine liquid, lime biogas liquid or azadirachtin EC Control sorghum aphids and stem borers; d. Harvesting: Harvest after 120 to 130 days after transplanting, but because the seeds are not insect-proofed with any medicine before sowing, they are easily infected by underground pests such as yellow ants and seedling blight, red leaf disease, etc. pest damage

[0006] Patent document [application number] CN201210342096.0 discloses "a high-yield, high-starch brewing sorghum cultivation and seed production method". The sorghum is composed of HV45A as the female parent and YN141R as the male parent. Sow in early and mid-May, with a seeding rate of 10-15kg per hectare, and 100,000-120,000 seedlings per hectare; apply enough base fertilizer, apply 200 kg of corn compound fertilizer when sowing, topdress nitrogen fertilizer when jointing, or apply corn compound fertilizer per hectare when ridged 200 kg of fertilizer, 200-250 kg of urea, no top dressing during the growth period, this method of cultivating sorghum is sown only in May, which affects the second harvest of sorghum and also wastes land
