Cold-zone japonica rice dry-seeding water pipe cultivation method

Abstract

The invention discloses a cold-zone japonica rice dry-seeding water pipe cultivation method, which comprises the following steps of: (1) land preparation before seeding, which comprises autumn rotary tilling and stubble cleaning, land flattening and spring rotary tilling and pulverizing; (2) seed preparation, which comprises variety selection and seed processing; (3) sowing; (4) fertilizer application, which comprises control on a fertilization quantity and a fertilizing mode; (5) water layer management, which comprises primary irrigation, water layer management in a tillering stage, water layer management in a jointing-booting stage and water layer management in heading, poplar blossoming and filling stages; (6) weeding, which comprises two modes of agricultural weeding and chemical weeding; (7) prevention and treatment of diseases and insect pests, which comprise grass cutting and cocoon removal and chemical prevention and treatment; (8) harvesting, which comprises determination of a harvesting period, a mechanical harvesting mode and a storage mode. Compared with the prior art, the cold-zone japonica rice dry-seeding water pipe cultivation method disclosed by the invention has the advantages that the dry-seeding water pipe cultivation method disclosed by the invention is a simple and water-saving cultivation mode, and can achieve unification of simplicity and water saving and high yield and high quality; the cold-zone japonica rice dry-seeding water pipe cultivation method adapts to the climatic characteristics of cold zones and is suitable for black soil, Baijiang soil and saline-alkali soil; sustainable development of production of japonica rice in the cold zones and improvement of productivity can be promoted.

Description

Technical field [0001] The invention relates to a rice cultivation method, in particular to a water pipe cultivation method for dry sowing japonica rice in cold regions. Background technique [0002] At present, in the cold rice regions such as Heilongjiang Province, affected by factors such as labor shortage and water scarcity, the labor-intensive and low water use efficiency of seedling transplanting methods have become an impact on the sustainability and productivity of cold rice production. Important factor. Dry sowing water pipe is a light and water-saving cultivation method, with the goal of lightness, water saving, high yield and high quality. Therefore, inventing a dry-sowing water tube cultivation method for japonica rice in cold regions has become an urgent problem for those skilled in the art. Summary of the invention [0003] In order to solve the above-mentioned shortcomings, the present invention provides a water tube cultivation method for dry sowing japonica rice...
