Problems solved by technology

[0003] To sum up, the problems existing in the existing technology are: the terrain in the south is mountainous and hilly, and large-scale mechanized operations are difficult, especially during the period of double-cropping and double-grabbing rice, which is sunny, hot and high temperature. The shortage of rural labor and the rapid increase in costs gradually restrict the large-scale planting of rice. efficiency and effectiveness

Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] The application principle of the present invention will be further described below in conjunction with the accompanying drawings.

[0020] like figure 1 As shown, the rice double-cropping and double-spraying direct seeding planting technology method provided by the embodiment of the invention comprises the following steps:

[0021] S101: Selected varieties, reasonable collocation: choose different seeding rates according to different rice varieties, soak seeds early to germinate half grain length, and soak seeds late to break the chest and reveal white;

[0022] S102: Timely and uniform spraying for direct seeding:...

Abstract

The invention belongs to the technical field of rice planting, and discloses a rice double-season double-spraying direct seeding cultivation method. The method comprises the following steps: selectingthe seeding quantity according to rice varieties, soaking early rice seeds and accelerating germination until the bud length reaches the half length of a grain, and soaking late rice seeds until theseed coats are broken and white buds are exposed; before seeding, leveling the field and discharging water thoroughly; carrying out sealing and weeding; carrying out fertilizer arrangement; and carrying out disease and pest prevention and control. According to the cultivation method provided by the invention, the seeds subjected to germination acceleration are uniformly seeded into a rice field through the match of a manpower backpack powder spraying machine and a scattering nozzle, a corresponding cultivation management mode is carried out, and the processes such as double-season seedling raising, seedling pulling, rice transplanting and the like are omitted, so that the planting operation process of the two-season rice planting in south areas can be simplified to a maximum extent, the work efficiency is improved, the labor force is saved, adaption with the appropriate scale operation of rural land is achieved, and thereby the income benefit of farmers is promoted.

Description

technical field [0001] The invention belongs to the technical field of rice planting, and in particular relates to a double-cropping and double-spraying direct seeding cultivation method for rice. Background technique [0002] Existing double cropping rice varieties can be divided into early rice conventional rice and hybrid rice, late rice conventional rice and hybrid rice. Traditional rice transplanting requires multiple processes such as seedling raising, pulling out and transplanting, which is labor-intensive, low in productivity, and difficult for mechanized operations, which consumes a lot of manpower and material resources. [0003] To sum up, the problems existing in the existing technology are: the southern terrain is mountainous and hilly, and large-scale mechanized operations are difficult, especially during the period of double-cropping rice and double harvesting, which is sunny, hot and high temperature. The shortage of rural labor and the rapid increase in cost...
