A strip planting method for mechanically harvesting millet without ear entanglement

Abstract

The invention provides a strip plantation method capable of preventing twining of grain ears in mechanical millet harvesting. The strip plantation method is implemented in cooperation with matching integrated wheat rotary tillage, sowing and pressing machine and a matching wheat harvester, aims to prevent twining of grain ears at border rows and is applicable to mechanical harvesting of millets sowed in spring and summer. The strip plantation method comprises the following steps: dividing plantation points; setting distribution manners of row numbers of both type A plantation and type B plantation, wherein the distribution manner of the row numbers of the type A plantation is that seven rows including rows 1, 3, 5, 7, 9, 11 and 13 are not sowed and six rows including rows 2, 4, 6, 8, 10, 12 are sowed, and the the distribution manner of the row numbers of the type B plantation is that six rows including 1, 3, 5, 9, 11, 13 are sowed and seven rows including rows 2, 4, 6, 7, 8, 10, 12 are not sowed; carrying out sowing, wherein sowing is carried out from one side of a terrace, a first machine carries out sowing according to the distribution manner of the row numbers of the type A plantation at first, then a second first machine carries out sowing according to the distribution manner of the row numbers of the type B plantation, and a third carries out sowing according to the distribution manner of the row numbers of the type A plantation so as to finish sowing of a plantation unit; and carrying out harvesting by using the wheat harvester, wherein one wheat harvester can harvest one plantation strip.

Description

technical field [0001] The invention relates to a strip planting method for mechanically harvesting millet without ear winding. Background technique [0002] At present, the annual planting area of ​​millet in the country is about 20 million mu, 60% of which are distributed in Hebei, Shanxi, and Inner Mongolia in North China. In recent years, with the maturity of millet-free thinning planting technology and chemical weeding technology, the production cost of millet has been reduced, farmers' enthusiasm for planting millet has increased, and its sown area has increased year by year. Another restrictive factor that plagues millet production at present is that millet harvesting requires a lot of labor, and the cost is high, which directly affects its economic benefits. In recent years, scientific and technological workers have carried out more research on mechanized harvesting. Shanxi Agricultural University has introduced and refitted the "Kubota" combine harvester. Gaoping H...

AI Technical Summary

Problems solved by technology

At present, most spring sowing millet adopts the cultivation mode of small groups (about 20,000-40,000 plants per mu for precision seeding), large individuals (the ears are ≥20cm and curved) and small sowing row spacing (about 30-35cm). The entanglement of grain ears between rows is more serious

Therefore, the conventional planting methods of the previous spring sowing millet cultivation model are difficult to adapt to mechanized harvesting
