Problems solved by technology

[0005] Aiming at the problems of difficult topdressing, large amount of fertilization, high loss, shortage of labor force, serious lodging, and low degree of sowing mechanization in the production process of hole-directed rice, the present invention provides a light-duty cultivation method of mechanical hole-directed rice, which fully utilizes agricultural machinery, agronomy, and agricultural fertilizers. The organic combination of agricultural technology greatly reduces labor intensity, improves labor efficiency, reduces labor costs, promotes farmers' income increase on the premise of ensuring food security, and realizes green and light rice production

Embodiment Construction

[0024] From June to October 2017, the light cultivation method of direct-seeding rice in mechanical holes was implemented in Zhonglong Town, Chaohu City, Anhui Province.

[0025] Wheat mechanized crushing and returning to the field: On May 15, the wheat was harvested with a wheat combine harvester, and the wheat straw was chopped to a length of 1-5cm by the straw cutting device attached to the harvester, and evenly sprinkled on the field surface;

[0026] Soil preparation: On May 18, the field surface was irrigated with 3-5cm of water to soak the field. The medium-sized tractor was equipped with a grass-burying rotary tiller to complete the grass-burying and site preparation at one time, and the burial depth of the wheat straw returning to the field was 5-10cm. The field surface is 10-15cm, and the field surface after site preparation is muddy or maintains an aquifer of 1-3cm, the field surface is flat, and the height difference is 0-3cm;

[0027] Rice seed selection and treat...

Abstract

The invention discloses a light cultivation method of rice by mechanized hill-direct-seeding, comprising the steps, such as mechanized crushing and returning of wheat, land preparation, rice seed selection, rice seed treatment, seed and fertilizer synchronization in mechanized hill-direct-seeding, moisture management, disease and pest damage control, mechanized harvesting, and straw returning. Themechanized manner replaces the manual manner to arrive at light cultivation of rice by hill direct seeding. Compared with traditional rice planting modes, the method of the invention employs seed andfertilizer synchronization in mechanized hill-direct-seeding to achieve single fertilizer application for rice, and the difficulty in rice topdressing is overcome; fertilizer is applied below the lateral side of rice seeds, the problem that contact between the fertilizer and the seeds affects seed germination is avoided, rice root burning is avoided, downward growth of seed roots is promoted, theability of hill-direct-seeded rice to resist lodging is enhanced, and green yield increase and efficiency increase for rice are promoted.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and in particular relates to a light-type cultivation method of mechanical hole direct-seeding rice. Background technique [0002] Rice is the food crop with the largest planting area and the highest yield per unit area and total output in my country. In the production of grain crops, the labor intensity of rice cultivation is the highest (mainly transplanting and raising seedlings), and with the development of rural economy and the adjustment of industrial structure, a large amount of labor is transferred to the secondary and tertiary industries. Therefore, it is necessary to simplify rice cultivation and reduce labor. Intensity of light cultivation techniques are getting more and more attention. Studies have shown that mechanical hole-directed rice is superior to manual transplanting in terms of the highest number of seedlings, number of spikelets per panicle, and number of sol...
