Embodiment 1

[0025] From June to October 2016, the light cultivation method of direct-seeding rice with mechanical strips was implemented in Zhonglong Town, Chaohu City, Anhui Province.

[0026] Wheat mechanized crushing and returning to the field: On June 5, the wheat was harvested with a wheat combine harvester, and the wheat straw was chopped to a length of 1-5 cm by the straw cutting device attached to the harvester, and evenly sprinkled on the field surface;

[0027] Soil preparation: On June 8, large or medium-sized tractors equipped with a grass-burying rotary tiller will complete the grass-burying and soil preparation at one time by operating both horizontally and vertically. The burial depth of wheat straw returning to the field is 5-10cm, and the depth of rotary tillage soil preparation is 10-20cm;

[0028] Rice seed selection and treatment: buy coated rice seeds in the market, the varieties are Liangyou 100, Guangliangyou 6308, Huiliangyou 630, and Longliangyou;

[0029] Synchro...

Embodiment 2

[0038] From June to October 2017, the light cultivation method of direct-seeding rice with mechanical strips was implemented in Zhonglong Town, Chaohu City, Anhui Province.

[0039] Wheat mechanized crushing and returning to the field: On June 6, 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.

[0040] Soil preparation: On June 9, large or medium-sized tractors equipped with a grass-burying rotary tiller will complete the grass-burying and soil preparation at one time by operating both horizontally and vertically.

Abstract

The invention discloses a mechanical row and direct seeding paddy rice light cultivation method. The mechanical row and direct seeding paddy rice light cultivation method includes aspects of mechanical wheat straw smashing and returning, land preparation, rice seed selection and treatment, mechanical row and direct seeding and fertilizing synchronization, water management, disease and insect pestprevention and control, mechanical paddy rice harvesting, rice straw returning and the like. The mechanical row and direct seeding paddy rice light cultivation method has the advantages that the problems of repeated fertilization, difficulty in top dressing, tedious cultivation measures and high labor intensity of the traditionally planted paddy rice, severe diseases and insect pests and susceptibility to lodging of directly seeded paddy rice and the like can be solved by the aid of the mechanical row and direct seeding paddy rice light cultivation method; the paddy rice planting cost can be saved, the paddy rice planting comprehensive mechanization level can be upgraded, the resource utilization rate can be increased, and agricultural green and sustainable production can be 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 for direct-seeding rice by mechanical strips. Background technique [0002] Rice is the main food crop in my country, and more than 60% of the country's population uses rice as a staple food. With the continuous innovation of agricultural technology, my country's agriculture has begun to face a period of opportunity for industrial transformation. As more and more scientific and technological achievements are introduced into agricultural production, increasing the growth rate of food production has also ushered in an important opportunity. [0003] Mechanized rice planting is an important part of the new technology field. At present, great progress has been made in the world's major rice-growing countries, and it has been widely used in production. In recent years, my country has experienced a relatively scarce labor fo...
