Problems solved by technology

However, this method has the following disadvantages: the one is that the seedling stage is dry for a long time, and the growth period of rice is delayed, and most of them are delayed for more than 10 days; Dry farming does not maintain the water layer, the soil is moist, weeds are easy to grow and there are many types of weeds, the damage is serious, and the effect of artificial weeding is poor; fourth, due to unclear indicators for artificial water replenishment at different growth stages, droughts and reduced yields; Fifth, artificial water replenishment increases labor intensity and high cost

Embodiment 1

[0026]Direct seeding planting of rice in dry land, the method is as follows:

[0027] (1) Soil preparation stage before sowing

[0028] Select a dry field where wheat is planted, and weed with herbicides 15 days before sowing; 3 days before sowing, tractor dry-rotary plowing and harrowing, so that the loose soil layer is 15-20cm; apply base fertilizer within 1-2 days before sowing, and dry again Rotary harrowing field, so that the loose soil layer and the base fertilizer are evenly mixed; the applied base fertilizer is a mixture of diammonium phosphate, ammonium sulfate and potassium sulfate, and the application rate is 7.5kg / 667m 2 、10.0kg / 667m 2 、5.0kg / 667m 2 ; Keep the relative water content of the soil above 70% before sowing;

[0029] (2) soaking and sowing

[0030] The rice variety selected was "Yanfeng 47".

[0031] Paddy rice seed adopts interval seed soaking method to process 36 hours, gets soaking seed, and described interval soaking method is seed soaking and d...

Embodiment 2

[0044] Direct seeding planting of rice in dry land, the method is as follows:

[0045] (1) Soil preparation stage before sowing

[0046] Select the dry field where wheat is planted, and weed with destructive herbicide 15 days before sowing; 5 days before sowing, tractor dry-rotary plowing and harrowing the field, so that the loose soil layer is 15-20cm; apply base fertilizer within 1-2 days before sowing, and dry again Harrow the ground so that the loose soil layer is mixed evenly with the base fertilizer; the base fertilizer applied is the purchased long-acting slow-release compound fertilizer, and the application rate is 40kg / 667m 2 ; Keep the relative water content of the soil above 70% before sowing;

[0047] (2) soaking and sowing

[0048] The rice variety selected was "Tianyou 998".

[0049] Paddy rice seed adopts interval seed soaking method to process 40 hours, gets soaking seed, and described interval soaking method is seed soaking and dew seed interphase, and desc...

Abstract

The invention relates to a rice dry land direct-seeding planting method. The planting method includes the first step of seedbed preparation, the second step of seed soaking and seeding, the third step of mulch covering and the fourth step of management after seeding. According to the rice dry land direct-seeding planting method, seeds are directly and evenly mixed with drought resisting agents and water to form a jelly-like substance containing the seeds and the jelly-like substance is sown in a dry land and is covered by mulch. The method greatly improves the drought resisting level in the whole process of rice production and eliminates the working procedures like rice seedling raising and rice seedling transplanting in a traditional rice cultivation mode under flood. Compared with other rice dry farming methods, the rice dry land direct-seeding planting method has the advantages that the method is simple in operation and management, emergence of rice seedlings is tidy, the percentage of seedling emergency is higher and the yield is higher.

Description

technical field [0001] The invention belongs 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...
