Oilseed rape transplanting method and special transplanting machine

Abstract

The invention relates to an oilseed rape transplanting method, which belongs to the field of agricultural technologies. The method comprises the following steps: after a non-woven fabric is laid at the bottom of a normalized seedling raising tray matched with a transplanting machine, spreading soil and watering, sowing a scheduled number of rape seeds, covering the seeds by using soil, and carrying out watering and fertilizing on the seeds, so that after seedlings grow to 4-5 leaf periods, normalized blanket seedlings with a root system mutually interlaced with the non-woven fabric are formed; screening seedling raising soil by using a mesh screen with a mesh side-length of 4 mm; carrying out ditching so as to form rectangular pieces of land in a field according to the integer-multiple width of the operated row number of the transplanting machine, and carrying out irrigation so as to wet the field through the rectangular pieces, wherein the tillage depth is greater than 15 cm; and taking and placing the normalized blanket seedlings into a seedling box of the transplanting machine, and driving the transplanting machine to the field to carry out a transplanting operation. According to the invention, an effect of automatic seedling supply and high-speed transplanting can be achieved, the auxiliary labor is less, the transplanting efficiency is high, and under the same conditions, the operating efficiency is 5-8 times as large as that of the existing chain-clamp type rape oilseed transplanting machine, therefore, the operation cost is greatly reduced.

Description

technical field [0001] The invention relates to a rapeseed planting method—a transplanting method, and also relates to a special transplanting machine for realizing the method, which belongs to the field of agricultural technology. Background technique [0002] my country's rapeseed planting area is more than 90 million mu, of which 70% are planted by seedling transplanting. The crop rotation of rice and rapeseed is the main cropping system. In order to meet the requirements of two crops or even more crops a year, and to shorten the growth cycle of rapeseed in the field as much as possible, for a long time, rapeseed has been using: artificial sowing in seedling fields-manual pulling out of seedlings after they have grown into seedlings-manual transplanting of rapeseed seedlings to the field The planting method of transplanting is commonly known as artificial bare seedling transplanting. This rapeseed planting method uses a lot of labor, high labor intensity, and low produc...

AI Technical Summary

Problems solved by technology

It is obviously inapplicable to use it for the production of rape seedlings that require soil seedlings, and the production efficiency is low, the need for seedling trays is large, and the cost is high

[0005] It can be seen from the above-mentioned prior art that transplanting of rapeseed has received widespread attention. However, although the existing two kinds of equipment can realize semi-mechanized or mechanized transplanting of rapeseed, the former uses a chain clamping planting mechanism, which needs to be used. Manual feeding of seedlings has the disadvantages of low operating efficiency and the use of a lot of labor and is easy to damage the seedlings. The latter uses rapeseed seedlings, which have high seedling cost, and the structure of the machine is complicated, the cost is high, and the operating efficiency is low.

Therefore, it is difficult to promote the application
