Rice cultivation method

Abstract

The invention discloses a rice cultivation method. The rice cultivation method comprises the following steps of: S10, preparing before seeding; S20, carrying out seeding operation; S30, carrying out irrigation by infiltration on a rice field in a whole growth period when the rice enters the growth period, and carrying out pest control and grass disaster control; and S40, timely harvesting according to the rice growth period and carrying out planting on next round of crops. According to the rice cultivation method disclosed by the invention, no-tillage direct seeding and irrigation by infiltration are organically combined, so that the no-tillage direct seeding saves a rice seedling bed period; and flooding irrigation is replaced by the irrigation by infiltration, so that the technical problems that the conventional rice cultivation technology is high in seedling transplanting and greenhouse gas discharging amount, and lower in fertilizer and moisture utilization efficiency are solved, energy-saving and emission-reducing capacity of a rice producing system is improved, and purposes of saving the oil consumption by 45%, comprehensively reducing emission of the greenhouse gas by 50% and remarkably improving the water fertilizer utilization efficiency are achieved; and moreover, the rice cultivation method is higher in mechanical degree, simplified in technology, easy to popularize, and especially has popularization prospect in a rice-wheat (oilseed rape) paddy-upland rotation region.

Description

technical field [0001] The invention relates to an agronomic method for planting crops in the field of agricultural technology, in particular to a rice cultivation method. Background technique [0002] Paddy field is the most important farmland ecosystem in my country. Although its total area only accounts for 20% of my country's cultivated land area, it produces nearly 50% of my country's grain. While rice fields ensure my country's food security, they are also CH 4 and N 2 An important source of greenhouse gas emissions such as O. Currently 16% of global CH 4 Emissions are generated from rice fields, and Chinese rice fields contribute to global CH 4 The contribution of emissions is about 22% to 32%, CH in paddy fields 4 Emissions will become a new focus of international negotiations on energy conservation and emission reduction. On the one hand, straw returning can promote the increase of farmland soil carbon, reduce the amount of chemical fertilizers and improve the...

Problems solved by technology

Machine transplanting is the main cultivation technology promoted by the government. With the strong support of the government, it has developed rapidly, but the cost is high, and it is difficult to popularize it on a large scale in a short period of time.

As a light and simple rice cultivation mode, direct-directed rice has the advantage of low operation cost, which is favored by farmers and has a strong development momentum; however, there are many problems in actual production, such as unstable yield and serious lodging, especially the traditional A handful of seeds and a handful of fertilizers are used for direct seeding, resulting in high greenhouse gas emissions and low water and fertilizer use efficiency, which limits the popularization and application of direct seeding rice technology
