Embodiment 1

[0028] A kind of paddy rice no-tillage film mulching cultivation method comprises the following steps:

[0029] 1) Repairing the field surface: the potholes and high ridges left on the surface of the box after harvesting in the previous crop should be repaired and repaired, and the field ditch system should be dredged and separated. The width of the box surface is 1.8m, and the width of the ditch is 20cm;

[0030] 2) Weeding and stubble removal: 15 days before sowing, under the condition of no rain and no water on the field surface, use 200 ml of Gramoxone water agent, mixed with 50 kg of water, to wet and spray the weeds in the whole field; dry for 1 day after spraying , irrigate the water layer 5cm above the van surface and keep it for 5 days to soften the field;

[0031] 3) Base fertilizer application: drain the field water, keep the compartment surface moist, apply base fertilizer on the compartment surface, the amount of base fertilizer is 30 kg per mu; base fertilizer is...

Abstract

The invention discloses a no-tillage covering film cultivation method for paddy rice, belonging to the field of paddy rice cultivation methods. The cultivation method comprises the steps of trimming the surface of the field, weeding and ploughing stubble, applying basal fertilizer, covering film and punching holes, sowing and managing the field; water can be conserved through the covering of the mulching film on the ridge surface, soil erosion is reduced, so that soil biological development is promoted, and soil biodiversity is enriched; compared with conventional planting, the application amount of the herbicide and the chemical pollution can be reduced. The invention solves the technical problems that the production cost is high, the difficulty is large, and the working efficiency is low through the mode of no-tillage of the land and seed direct seeding during a tillage process or a seedling transplanting process, and social and economic benefits are improved.

Description

technical field [0001] The invention relates to the field of rice cultivation methods, in particular to a no-tillage and film-covered rice cultivation method. Background technique [0002] In the rice cultivation method in the prior art, the rice seedling throwing cultivation is usually carried out after the farmland is plowed first. Its disadvantages are that it is labor-intensive, the cost of farming is high, and the plowing of the land will also destroy the soil structure, resulting in the loss of water and organic matter. Rice is one of the most important food crops in southern my country, and it is also an important source of non-point source pollution. How to improve the traditional rice planting method, improve soil fertility and reduce the use of chemical fertilizers while maintaining the original yield has become an urgent problem to be solved. In this case, new requirements are put forward for rice cultivation technology, and traditional technology has been diffi...
