Planting method and equipment for shallow plowing, weeding, ditching and soil covering

Abstract

The invention discloses a planting method and planting equipment for shallow plowing, weeding, ditching and soil covering. Synchronous operations of shallow plowing, weeding, stubble cleaning, ditching and soil covering are performed by mainly adopting a shallow plowing and ditching mechanism; shallow plowing, weeding, stubble cleaning, ditching and soil covering functions are performed on high rice stubbles of a rice stubble field at one time; the ditching depth is controlled at 15 to 20 centimeters, and the shallow plowing depth is 3 to 5 centimeters; a right-angled blade inclination installing method is adopted in a shallow plowing blade, or a bent cutter is vertically arranged on a cutter shaft, and a rotary plowing and ditching cutter head is arranged in the middle of the cutter shaft; in order to ensure normal functions of shallow plowing and weeding, the overlapping rate of the two adjacent blades is in a range of 0.5 to 1 centimeter when the shallow plowing blades are arranged; and the distance between the shallow plowing blade installation positions on two sides of the rotary plowing cutter head should be 5 to 6 centimeters so as to ensure the stability of a drilled drainage ditch.

Description

technical field [0001] The invention relates to a rapeseed mechanized planting production process, which is particularly suitable for the rapeseed mechanized planting method and equipment in rice stubble fields. Background technique [0002] The existing rapeseed planting method is mainly to open drainage ditch, sow, fertilize and cover soil with seed fertilizer after harvesting of one-season rice or late rice. Since a large amount of high rice stubble and weeds (≤60cm) remain in the field after mechanized harvesting, It affects the follow-up sowing operation, and has a great impact on the rowing and uniformity of the seeds. In particular, it is difficult to ensure the position of the seeds falling, and some seeds will fall on the straw, resulting in a low germination rate of the seeds in the field, which seriously Affected the overall number of seedlings emerging in the field after sowing. Due to the existence of high rice stubble and weeds, if they are not removed in time...

[0002] The existing rapeseed planting method is mainly to open drainage ditch, sow, fertilize and cover soil with seed fertilizer after harvesting of one-season rice or late rice. Since a large amount of high rice stubble and weeds (≤60cm) remain in the field after mechanized harvesting, It affects the follow-up sowing operation, and has a great impact on the rowing and uniformity of the seeds. In particular, it is difficult to ensure the position of the seeds falling, and some seeds will fall on the straw, resulting in a low germination rate of the seeds in the field, which seriously Affected the overall number of seedlings emerging in the field after sowing

Due to the existence of high rice stubble and weeds, if they are not removed in time, they will continue to grow and consume part of the nutrients in the soil, which also brings certain difficulties to chemical weeding

At present, rape planting mainly promotes no-tillage direct seeding, but the soil surface of no-tillage is difficult to provide a good seedbed environment for seeds, which is not conducive to the growth and development of the root system. If the method of sowing after plowing is used, it will be difficult to produce due to the high cost to promote
