Problems solved by technology

However, there are also many problems in the cultivation of dry rice
For example, dry land preparation is more labor-intensive, especially in areas with heavy clay soil; it is not possible to irrigate and wash salt before sowing, and it is not suitable for dry farming in heavily saline-alkaline land; dry land for rice does not maintain water layers, and the soil is moist, and weeds are easy to grow and grow. There are many types of weeds, serious hazards, and poor artificial weeding effect, which increases the production cost of the enterprise and reduces the core competitiveness of the enterprise's market, etc.

Embodiment 1

[0019] A kind of direct seeding planting of paddy rice comprises the following steps:

[0020] S1. Soil preparation stage before sowing: select the dry field where wheat is planted, weed with herbicide 13 days before sowing; Apply the base fertilizer within 3 days, dry and rake the ground again, so that the loose soil layer and the base fertilizer are mixed evenly; the applied base fertilizer is a mixture of diammonium phosphate, ammonium sulfate and potassium sulfate, and the application rate is 7.0kg / 667m 2 、9.0kg / 667m 2 、4.0kg / 667m 2 ; Keep the relative water content of the soil above 60% before sowing;

[0021] S2. Seed soaking and sowing: the selected rice variety is "Yanfeng 47", and the rice seeds are treated with an interval seed soaking method for 38 hours to obtain soaked seeds. The interval seed soaking method is alternating between soaking seeds and exposed seeds, and the soaking time is 10 hours. The dew time is 9 hours; then the soaked seeds are germinated at ...

Embodiment 2

[0030] A kind of direct seeding planting of paddy rice comprises the following steps:

[0031] S1. Soil preparation stage before sowing: select a dry field where wheat is planted, and use a herbicide to kill weeds 15 days before sowing; 7 days before sowing, use a tractor to dry and harrow the field so that the loose soil layer is 15-22 cm; 2-22 cm before sowing Apply the base fertilizer within 3 days, dry and rake the ground again, so that the loose soil layer and the base fertilizer are mixed evenly; the applied base fertilizer is a mixture of diammonium phosphate, ammonium sulfate and potassium sulfate, and the application rate is 10.0kg / 667m 2 、14kg / 667m 2 、5.0kg / 667m 2 ; Keep the relative water content of the soil above 60% before sowing;

[0032] S2. Seed soaking and sowing: the selected rice variety is "Tianyou 998", and the rice seeds are treated with an interval seed soaking method for 55 hours to obtain soaked seeds. The interval seed soaking method is alternating ...

Abstract

The invention relates to a direct seeding planting method for rice on dry field. The method comprises the following steps: S1, soil preparation stage before seeding; S2, seed soaking and seeding; S3, coverage of covering; and S4, management after seeding. According to the direct seeding planting method for the rice on dry land provided by the invention, seeds are directly mixed with a drought resistant agent and water uniformly to form gelatinous substances containing the seeds, the gelatinous substances are planted in the dry land, and then a layer of covering covers the dry land. The direct seeding planting method for the rice on dry field has the beneficial effect that according to the planting method, the seedling stage after direct seeding is short; emergence rate and survival rate of seedlings are increased; drought resistant level of the rice in the whole production process is improved remarkably; frequent watering and irrigation are not required; and labor management cost is low.

Description

technical field [0001] The invention relates to the technical field of agriculture, and in particular relates to a direct seeding planting method of rice in dry land. Background technique [0002] Rice is the largest food crop in my country, and it is also the largest user of water use. About 70% of agricultural water is used for rice irrigation. With the growth of population, the development of cities and industries, the change of global climate and the aggravation of environmental pollution, the water resources used for crop irrigation are becoming more and more scarce, which seriously threatens the development of crops, especially rice production. [0003] The direct seeding planting method of rice in dry land is developed from the direct seeding method of rice, that is, selecting drought-tolerant varieties, direct seeding in dry land conditions, long seedlings, and using rainwater and proper irrigation in the middle and late stages to meet the water demand of rice plants...
