Embodiment 1

[0025] The experiment was conducted in 2012 and 2013.

[0026] Test location: Yongchuan District, Chongqing City.

[0027] Test group A: The waxy sorghum species used in the test was the local conventional waxy sorghum, and the milk vetch was Minzi 6. Milk vetch was planted in mid-October in 2011 and 2012, and the plants were turned into the soil in early April of the second year, with a width of 90 cm and covered with plastic film; waxy sorghum was planted in early March in 2012 and 2013 , transplanted in early April of the same year, planted two rows of glutinous sorghum in each box, row spacing 50cm, hole spacing 38cm, 2 plants per hole, in early July of the same year, first-season glutinous sorghum was harvested, stems were cut within 2 days after harvest, and tillers were broken in the middle and late ten days , leaving 2 seedlings in each hole, harvested in early October of the same year.

[0028] Control group B: Waxy sorghum was planted, milk vetch was not planted, a...

Embodiment 2

[0033] Example 2, the test was carried out in 2012 and 2013 respectively.

[0034] Test location: Yongchuan District, Chongqing City.

[0035] Test group A: The waxy sorghum species used in the test was Lunuo 13, and the milk vetch was Minzi 6. Milk vetch was planted in mid-October in 2011 and 2012, and the plants were turned into the soil in early April of the second year, with a width of 90 cm and covered with plastic film; waxy sorghum was planted in early March in 2012 and 2013 , transplanted in early April of the same year, planted two rows of glutinous sorghum in each box, row spacing 50cm, hole spacing 38cm, 2 plants per hole, in early July of the same year, first-season glutinous sorghum was harvested, stems were cut within 2 days after harvest, and tillers were broken in the middle and late ten days , leaving 2 seedlings in each hole, harvested in early October of the same year.

[0036] Control group B: Waxy sorghum was planted, milk vetch was not planted, and plas...

Abstract

The invention relates to the technical field of crop planting, in particular to a high and stable yield cultivation method of double-cropping glutinous sorghum. By means of the measures of reasonably arranging growth periods of the glutinous sorghum and milk vetch, ditching and mulching, timely cutting poles, harvesting and the like, high and stable yields of the double-cropping glutinous sorghum are achieved. The cultivation method has the advantages that (1) by means of coordinating the growth periods of the glutinous sorghum and the milk vetch, one-crop green manure is additionally planted, diseases, insect pests and weeds are reduced, and successive cropping obstacles of the glutinous sorghum are reduced; (2) ditching and mulching are reasonably carried out, organic liquid dung is additionally applied, straws of the milk vetch are returned to the field at a higher speed, the function of the green manure on improving soil fertility is achieved, and soil is improved; (3) the growth period of the glutinous sorghum can be shortened by 3-11 days, and the yield of the double-cropping glutinous sorghum is increased by 120-200 kilograms with a growing rate of 15% - 33%.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to a high-yield and stable-yield cultivation method for double-season glutinous sorghum. Background technique [0002] Sorghum is the fourth largest food crop in the world after rice, corn and wheat. Sorghum is rich in nutrition. Every 100g of sorghum grain contains 8.4-14.5g of protein and 65.9-77.4g of starch. Waxy sorghum has unique tannins (tannins inhibit harmful microorganisms in the fermentation process and increase the special aroma of liquor), trace elements ( Components such as special taste), protein (special flavor) and starch (high alcohol yield) are important raw materials for the brewing industry. According to the survey of my country's sorghum market, the market demand for sorghum has increased, with an annual demand of 8 to 10 million tons, and the market has increased by more than 3 million tons. The market demand for sorghum seeds as the first raw material ...
