Embodiment 1

[0020] (1) Stubble removal and weeding: After harvesting the previous crop rice, leave the stubble below 15cm. For rice field fallow in winter, use glyphosate and other herbicides to kill weeds in the rice field about 30 days before planting rice, and weed the remaining large weeds before machine transplanting;

[0021] (2) Furrowing: Before planting rice, ditching is carried out, the ditch width is 0.3 cm, the ditch depth is 0.2 cm, and the distance between ditches is 6 m.

[0022] (3) Soaking the field: put water to soak the field before machine transplanting, the water depth is 15cm, the time for soaking the field is about 15 days, and the bulk density of the soil from the field to the surface layer 0-25cm reaches 0.9g / cm 3 the following;

[0023] (4) Machine transplanting: Before machine transplanting, select indica-japonica hybrid rice varieties such as Yongyou 12 15-20 days in advance, and raise seedlings according to conventional methods, with a seeding rate of 80g / pan...

Embodiment 2

[0026] (1) Stubble weeding and weeding: After harvesting the previous wheat, leave the stubble below 15cm. About 20 days before planting rice, use herbicides such as Roundup to kill weeds in rice fields, and weed the remaining large weeds before machine transplanting;

[0027] (2) Ditching: before planting rice, ditching treatment is carried out, the ditch width is 0.3 cm, the ditch depth is 0.2 cm, and the distance between ditches is 6.5 m.

[0028] (3) Soaking the field: Put water to soak the field before machine transplanting. The water depth is 10cm. 3 the following;

[0029] (4) Machine-transplanting: before machine-transplanting, select indica-type hybrid rice varieties such as Zhongzheyou No. 1 15-20 days in advance, raise seedlings according to conventional methods, with a seeding rate of 80g / pan, and raise seedlings until the height of the seedlings is 12-20cm; After completion, use a rice transplanter such as Yanmar VP-6 to carry out machine transplanting. When mac...

Embodiment 3

[0032] (1) Stubble removal and weeding: After harvesting the previous crop rice, leave the stubble below 15cm. For rice field fallow in winter, use glyphosate and other herbicides to kill weeds in the rice field about 30 days before planting rice, and weed the remaining large weeds before machine transplanting;

[0033] (2) Furrowing: Before planting rice, ditching is carried out, the ditch width is 0.3 cm, the ditch depth is 0.2 cm, and the distance between ditches is 6 m.

[0034] (3) Soaking the field: put water to soak the field before machine transplanting, the water depth is 15cm, the time for soaking the field is about 15 days, and the bulk density of the soil from the field to the surface layer 0-25cm reaches 0.9g / cm 3 the following;

[0035] (4) Machine transplanting: Before machine transplanting, select conventional japonica rice varieties such as Xiushui 134 15-20 days in advance, and raise seedlings according to conventional methods, with a seeding rate of 100g / pa...

Abstract

The invention provides a plantation method of paddy rice. The method comprises the following steps: a), stubbling and weeding: after preceding crops are harvested, performing stubbling, and carrying out weeding processing before the paddy rice is planted; b), trench digging: digging trenches before the paddy rice is planted; c), field steeping: discharging water to a field for steeping the field ten to fifteen days before machine-transplanted seedling, the depth of the water being 5 to 10cm, and steeping the field until the unit weight of surface soil is 0.9g/cm<3> below; d), machine planting: carrying out the machine planting when a water layer is 0.5 to1.5cm, the depth of the machine planting being 2 to 3cm; and e), performing field management. According to the tillage-free machine-transplanted seedling method provided by the invention, the soil of a rice field does not have to be ploughed by machinery, the soil is softened through steeping the field in the water before the machine planting, and the machine planting is carried out by use of a rice transplanter, such that the cultivation cost is decreased, the soil working link is reduced, rich-water loss is reduced, at the same time, the problem of easy fall of the rice transplanter into slurry, caused by too deep and too muddy conventionally ploughed slurry and the problems of turning-green and tillering of seedlings, affected by too deep insertion of the seedlings into the soil by use of a conventional ploughing machine are solved, and the machine planting yield is high.

Description

technical field [0001] The invention belongs to the technical field of crop planting, and in particular relates to a rice planting method. Background technique [0002] With the development of society and economy, the transfer and aging of the rural labor force, mechanized planting is the development direction of modern rice farming technology in my country. Mechanized rice transplanting technology uses high-performance rice transplanters instead of manual transplanting of rice seedlings. It is a technological revolution that further improves rice labor productivity after the update of varieties and cultivation techniques. In recent years, with the support of policies, rice machine transplanting has developed rapidly in my country, but a set of paddy field cultivation methods suitable for mechanized operations has not yet been formed. The traditional hand-transplanted paddy field soil cultivation method, the soil soaking time is too long, and the rotary tillage is too much,...
