Dislocation type corn planting method and reciprocating flashboard type seed and fertilizer sowing machine

Abstract

The invention relates to a dislocation type corn planting method and a reciprocating flashboard type seed and fertilizer sowing machine. The reciprocating flashboard type seed and fertilizer sowing machine comprises a seed box, a seed sowing pipe and a furrowing blade are arranged below a bottom plate of the seed box; a translational flashboard with a seed taking hole is arranged on the upper part of the bottom plate of the seed box; a closed isolation chamber is arranged above a seed sowing opening positioned at the bottom of the seed box and the flashboard; and the contact position of the lower part of a front wall plate of the isolation chamber and the flashboard is provided with a fur brush and a seed sowing press plate. The front end of the reciprocating flashboard type seed and fertilizer sowing machine is provided with a fertilizer box, a fertilizer sowing pipe, the furrowing blade and a fertilizer flashboard, wherein the fertilizer box is similar to a seed-metering device; the fertilizer flashboard and the seed flashboard are connected with same bearing and eccentric wheel together; and a drive shaft of the eccentric wheel is connected with a travelling wheel through a chain. In the dislocation type corn planting method, accurate mutual alternating sowing of seeds and fertilizers is carried out by using the reciprocating flashboard type seed and fertilizer sowing machine, the seeds are sown into adjacent rows in a dislocating way so that dislocating cavities positioned on the two adjacent rows are distributed in a triangular shape, and 2-5 seeds are sown into each cavity. The planting mode has the advantages of time and labor saving, reasonably enhanced planting density, lodging resistance, vigorous growth and sufficient solar thermal utilization of water fertilizers and can generally increase the yield of corns by more than 20-50 percent.

Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a misplaced corn planting method and a reciprocating plate-type seed and fertilizer simultaneous sowing machine. Background technique [0002] Maize is native to Mexico or Central America, with a cultivation history of 4,500 to 5,000 years. It is distributed in temperate, subtropical, and tropical regions between 58° north latitude and 40° south latitude. It can be grown from basins below sea level to areas above 3,600 meters above sea level. Planting is a typical multi-purpose high-yielding crop. Among all kinds of crops in the world, the total planting area and total output of corn ranks third after wheat and rice, and the output per unit area ranks first in the world's cereal crops. After years of development, my country's corn planting area has surpassed that of wheat to become the second largest crop in China after rice, and its per unit yield and total output have reac...

Problems solved by technology

However, the cultivation of maize in most areas of my country has been hovering at the level of medium and low cultivation density for a long time, which has restricted the increase of maize yield to a large extent.
