Seedling growing and transplanting method of corn, and mechanical transplanting machine matched with method

Abstract

The invention discloses a seedling growing and transplanting method of corn, and a mechanical transplanting machine matched with the method. The seedling growing and transplanting method of corn is suitable for seedling growing and transplanting of corn in the northern area and breaks through the bottleneck of a traditional manual method through which seedlings are separated one by one. The mechanical transplanting machine matched with the method can complete separation of a whole tray of seedlings from soil monomer at one time, and can complete a plurality of agricultural procedures, such as delivery of the seedlings, separation, launching, furrowing, earth covering and pressing at one time. The method is characterized in that seedlings are cultivated in a greenhouse; and then the seedlings are transplanted to the ground by the mechanical transplanting machine matched with the method; the transplanting machine comprises a land wheel, a conveyor belt, a small bevel wheel, a poking wheel, a large bevel wheel, double-edge sawteeth, a ploughshare, an earth covering and pressing wheel, a seedling receiver and a seedling containing cylinder, and a seedling growing tray comprises a tray support and a pot tray. In comparison with the traditional transplanting machine, the mechanical transplanting machine matched with the method is greatly increased in work efficiency, and the efficiency of a double-row machine of the transplanting machine is 10-15 times of the efficiency of manual transplanting, so that the large-area promotion of seedling growing and transplanting of corn becomes possible. According to the method and the machine, the traditional direct sowing mode of corn is changed and the production is generally increased by at least 20% compared with the production of direct sowing; in addition, the method and the machine are also suitable for the seedling growing and transplanting works of hot peppers, sorghum and the like.

Description

technical field [0001] The invention relates to a corn seedling raising and transplanting method and its supporting mechanized transplanting machine, in particular to a method suitable for corn seedling raising and transplanting in northern my country and breaking through the bottleneck of traditional manual separation of seedlings one by one; it can be done manually at one time It is a supporting mechanized transplanting machine that separates seedlings and soil from the whole plate, and mechanizes multiple agronomic operations such as seedling transportation, separation, placement, plowing, and soil covering and suppression at one time. Background technique [0002] Corn is one of the crops with the largest planting area in my country and the world. In the northern part of my country, the corn area is mostly planted in spring every year. At present, the main planting method of corn is field direct seeding, which has developed from artificial multi-seed sowing to single-grain...

Problems solved by technology

In order to supplement the accumulated temperature and prolong the growth period, plastic film mulching technology has been adopted in recent years, but the cost of plastic film mulching is high, and there are serious white pollution problems, which is not good for environmental protection and ecology, and cannot be widely promoted

[0003] Corn seedling transplanting can greatly increase the yield compared with field direct seeding, but there is no mature corn seedling transplanting method and supporting transplanting machinery in this area; the existing transplanting machinery has a complex structure, high cost, and needs to be grasped one by one manually Take the seedlings and separate the seedlings from the soil; the transplanting operation is cumbersome, labor-intensive, labor-intensive, low-efficiency, and high labor cost; the transplanting operation not only competes with spring farm work, but also takes a long time for transplanting, which is difficult to guarantee The best transplanting period delays farming time; therefore, it is difficult to promote corn seedling transplanting in a large area

Therefore, if the bottleneck of the cumbersome process of separation of seedlings and soil monomers cannot be broken through, the efficiency of corn seedling raising and transplanting work cannot be improved, making it difficult to show the grain increase and economic benefits of corn seedling raising and transplanting technology; Recognized, making its large-scale promotion a problem
