Embodiment 1

[0034] Step (1) The straw is crushed until the straw is broken, and then chopped into straw particles along the length of the straw, the length of the straw particles is 3 cm; the straw particles are soaked in the insect repellent solution for 30 min. Wood vinegar, garlic juice and water are prepared with a mass ratio of 1:1:10; the soil in the rice field is turned down 40cm, and straw particles are mixed into the turned soil. The mass ratio of straw particles to soil is 1:15; After mixing the straw and soil evenly, spread it in the paddy field as the upper layer of the paddy field; water the paddy field and water thoroughly; apply the first fertilizer 80kg per mu to the rice field, and the first fertilizer will be The following components are composed in parts by weight: 20 parts of ammonium nitrate, 3 parts of urea, 17 parts of potassium sulfate and 300 parts of pig manure;

[0035] Step (2) Select rice seeds with a germination rate above 98%, spread them out for 1 day, soak th...

Embodiment 2

[0040] Step (1) The straw is rolled until the straw is broken, and then chopped into straw particles along the length of the straw. The length of the straw particles is 5 cm; the straw particles are soaked in the insect repellent solution for 30 minutes. Wood vinegar, garlic juice, and water are prepared with a mass ratio of 1:1:10; the soil in the rice field is turned down 50cm, and straw particles are mixed into the turned soil. The mass ratio of straw particles to soil is 1:15; After mixing the straw and soil evenly, spread it flat in the rice field as the upper layer of the rice field; water the rice field, and the water must be poured thoroughly; apply the first 100kg of fertilizer per mu to the rice field, and the first fertilizer will be The following components are composed in parts by weight: 25 parts of ammonium nitrate, 7 parts of urea, 19 parts of potassium sulfate and 350 parts of pig manure;

Abstract

The invention discloses a method for water-saving rice cultivation in an improved rice field. The method comprises the steps of 1, grinding straw till the straw is broken and then cutting the straw into straw particles in the length direction of the straw; soaking the straw particles with pest expelling liquid; mixing the straw particles in turned soil; 2, soaking the straw particles with carbendazim liquor for 10 hours, then putting seeds into warm water at 55 DEG C to be preheated, mixing the seeds in wet straw and loading wet jute bags with the seeds; 3, transplanting rice seedlings in therice field; laying straw sections in the rice field, laying each layer of straw section in the same direction, laying two adjacent layers of straw sections in different directions, and after each layer of straw section is laid, laying a layer of soil and pressing a plastic screen sheet at the uppermost layer of the straw section; 4, keeping the depth of a water layer in the rice field at 6-8 cm; 5, applying fertilizer to the rice field per mu. The straw is adopted to improve the rice field, the water accumulating capability of the rice field is improved, and thus the purpose of saving water isachieved.

Description

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