Abstract

The invention discloses a water-saving rice cultivation method. The method includes: step (1), rolling straw until the straw is broken, cutting the straw along the length direction into straw grains,using pest repelling liquid to soak the straw grains, and mixing the straw grains into soil which is turned up, wherein the pest repelling liquid is prepared from wood vinegar, garlic juice and wateraccording to a mass ratio of 1:1:10; step (2), putting rice seeds into a wet jute bag; step (3), transplanting rice seedlings in a rice field, paving straw segments for 3-5 layers in the rice field, and watering after the straw segments are paved, wherein the straw segments on each layer are paved along one direction, the straw segments between each two adjacent layers are paved along different directions, and thickness of each layer is 0.1-1cm; step (4), 30 days after rice seedling transplanting, maintaining water in the rice field to 6-8cm in depth; step (5), fertilizing the rice field per mu. The straw is adopted to improve the rice field, so that water holding capacity of the rice field is improved, and the objective of saving water is achieved.

Description

technical field [0001] The invention relates to a water-saving rice cultivation method. Background technique [0002] At present, the utilization rate of water for rice cultivation in my country is not high, and the waste phenomenon is both serious and common. Whether it is traditional manual transplanting or modern machine transplanting, throwing and direct seeding of rice, the water consumption of one mu of rice is more than 450m3. For fields with severe leakage, the water consumption is even more alarming. In large-scale production, rice varieties with a growth period of 150 to 160 days generally require about 26 times of field irrigation in addition to water for raising seedlings, with an average of about 6 days. Contents of the invention [0003] It is an object of the present invention to solve at least the above-mentioned problems and to provide at least the advantages which will be described later. [0004] Another object of the present invention is to provide a...
