Soil leveling is mainly paddy field rotary tillage, which is time-consuming and labor-intensive and may also form low-lying and high ridges due to machinery; the sowing link is currently mainly used to sow or drill in the field manually or mechanically, and large-scale high-intensity operations will lead to poor human fatigue. Uneven seed distribution leads to large differences in seedling density; in the weeding process, due to the variety of grasses, there are many types of herbs, large quantities, and large differences in use time; the selection of insect and disease control time lags behind, and the effect of insect and disease control is not good; post-harvest rice treatment The large difference seriously reduces the commerciality of rice processing, which is not conducive to the stable development of the rice processing industry

[0072] After closed weeding on May 10, 2020, rice water weevil beetles appeared on the leaves of rice seedlings (2 leaves and 1 heart - 3 leaves and 1 heart), and drone spraying was carried out on May 18 to eliminate insects. After topdressing on the 19th, the barnyardgrass grew vigorously. On July 2, drone spraying was carried out to supplement the weeding. At the same time, in order to ensure the weeding effect, water was soaked in the field on July 10 to reduce the germination of new grass. The tender green leaves of rice seedli...

Abstract
The invention provides a method for producing commercial rice. The method comprises the steps that drainage ditches are formed around a dry farmland, and a rotary cultivator with a fender is used for rotary tillage and leveling in the farmland; seed germination accelerating and seed dressing treatment are carried out; sowing is carried out by using a disc-type sowing unmanned aerial vehicle; irrigating is intensively carried out to cover the field, and the water surface is flush with the field surface; a plant protection unmanned aerial vehicle is used for closed weeding and pesticide spraying; the plant protection unmanned aerial vehicle is used for insect prevention pesticide spraying; irrigation and fertilization are carried out; the plant protection unmanned aerial vehicle is used for performing stem and leaf weeding and pesticide spraying; irrigation and fertilization are intensively carried out, and a deep water layer of 3-5cm is kept; the plant protection unmanned aerial vehicle is used for insect prevention, disease prevention and leaf fertilizer spraying; draining and field drying are carried out; mechanical harvesting is carried out; and mechanical drying is carried out. According to the method for producing the commercial rice, development of an agricultural product processing industry chain is facilitated.
Description
technical field [0001] The invention belongs to the field of crop cultivation in the field of agricultural technology, and in particular relates to a direct seeding production method of rice. Background technique [0002] There are two ways of rice paddy production: seedling transplanting and direct seeding. The process of rice seeds germinating directly in the field, rooting and seedling emergence to harvesting is called direct seeding production. Rice live production mainly includes soil leveling, sowing, water management, fertility management, weeding, pest control, disease prevention and treatment, harvesting, and rice drying. Soil leveling is mainly paddy field rotary tillage, which is time-consuming and labor-intensive and may also form low-lying and high ridges due to machinery; the sowing link is currently mainly used to sow or drill in the field manually or mechanically, and large-scale high-intensity operations will lead to poor human fatigue. Uneven seed distribu...
