Direct-seeding rice efficiency-increasing and emission-reducing protection farming planting method

Abstract

The invention discloses a direct-seeding rice efficiency-increasing and emission-reducing protection farming planting method, which adopts protection farming, front crop straws and root stubbles in narrow planting rows and straws in wide fallow rows are intensively covered in the wide fallow rows without seeding, so that the straws are fully covered and returned to the field in a strip manner, shallow rotary seeding is only performed in the narrow planting rows, the stps of ploughing, field steeping and drainage in conventional culture are avoided, the situation that straw is enriched in a plough layer and affects the rice transplanting quality is avoided, and meanwhile the CH4 discharge amount and the greenhouse effect are reduced; on the other hand, the base fertilizer is intensively mixed and applied in the narrow planting rows, the fertilizer utilization rate is increased, and fertilizer waste caused by whole-field spreading is avoided; the marginal effect is fully utilized, and the group quality is improved; and an irrigation and drainage ditch system is matched, middle-stage drainage and field-placing management of the rice is facilitated, root system pricking is promoted, and ineffective tillering is controlled. The problems that a traditional mechanical transplanting culture mode is not high in fertilizer utilization rate, water deterioration is easily caused, and soil hardening is also caused are solved.

Description

technical field [0001] The invention relates to the technical field of rice cultivation, in particular to a protective tillage planting method for direct-seeding rice with enhanced efficiency and emission reduction. Background technique [0002] The basal fertilizer application of traditional machine transplanted rice seedlings is spread over the whole field, and the utilization rate of fertilizer is not high. Moreover, when the straw is returned to the field, the natural decomposition of the straw after soaking in the paddy field will release nitrogen, phosphorus and organic matter, which will lead to the deterioration of the water body. On the other hand, soaking in the field for a long time will also cause soil compaction, increase the difficulty of transplanting rice seedlings, and affect the effect of rice transplanting.
