Mis-sequence-sowing planting method for sorghum bicolor

Abstract

The invention discloses a mis-sequence-sowing planting method for sorghum bicolor. The method comprises the steps: (1) carrying out land preparation: before ploughing, broadcasting a well-composted organic fertilizer at the ratio of 30kg / mu to 37.5kg / mu and a compounded fertilizer at the ratio of 12kg / mu to 15kg / mu; and after ploughing, broadcasting the compounded fertilizer at the ratio of 6kg / mu to 7.5kg / mu, and carrying out spraying by using a 1,000-times diluted solution of methamidophos; (2) carrying out seed sorting and seed sun-curing: selecting large-grain full seeds, soaking the seeds by a potassium permanganate solution for 1 to 2 minutes, and then, carrying out sun-curing; (3) carrying out sowing, wherein the line width of each sowing line is 80cm to 90cm; in each sowing line, three pits form a planting group, and the group spacing is 28cm to 35cm; and in each planting group, the pit spacing is 3cm to 5cm, a single plant is located in a single pit, and first planting groups in five sowing lines are of mis-sequence arrangement in a manner of being away from planting lines by increasing 3cm to 4cm; (4) carrying out seedling finishing: carrying out replanting or thinning promptly with regard to seedling emergence conditions; and (5) carrying out fertilizer application. According to the planting method disclosed by the invention, balanced nutrient application and sorghum bicolor absorption are facilitated, roots among all groups of plants mutually cross and support, the spacing among the plants can be used for ventilating so as to weaken the pressure to the plants caused by the plants, and thus falling over can be effectively prevented.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a method for planting sorghum by staggered sowing. Background technique [0002] Sorghum is one of the important cereal crops cultivated by humans. It is second only to wheat, rice, corn, and barley, and ranks fifth in the world's food crops. Sorghum is an annual herbaceous plant, which can be directly eaten or fed, and can also be processed and utilized. In recent years, domestic and foreign studies on sorghum deep processing have developed rapidly. In addition to the traditional use of sorghum as staple food, brewing liquor, beer, and making feed, etc., a variety of processing uses of sorghum have also been beneficially explored. For example: use sweet sorghum stalks to make wine, use forage sorghum as silage and silage, use sorghum to produce alcohol, use sorghum husks to extract pigments, use sorghum grains to extract starch, produce sorghum bread, sorgh...

Problems solved by technology

[0003] The traditional sorghum planting method is mixed planting. Due to the mutual influence between sorghum, the lodging resistance of sorghum is very poor, and lodging often occurs in patches, causing serious economic losses.

In addition, this mixed planting method leads to uneven distribution of soil nutrients, and the phenomenon of lack of seedlings and burning seedlings often occurs, which wastes precious land resources to a certain extent.

For this reason, people have proposed a planting method of mulching to preserve moisture. The sorghum is planted in an orderly arrangement. Although the balanced distribution of water and nutrients is guaranteed, this method, due to the lack of buffering effect, reduces the wind resistance and lodging resistance of sorghum. , and the planting density of this method is small, so that land resources cannot be used more

In addition, during the planting process of orderly arrangement, strong seedlings or plants block the sunlight of low seedlings or weak seedlings due to competition, making the weak seedlings or plants weaker, which is not conducive to planting efficiency.
