Embodiment 1

[0034] Using the high-efficiency and precise water direct-seeding method of mid-season rice in a certain area of ​​Tuanfeng County, Hubei Province, the production of "Guangliangyou 476" was tested and planted:

[0035] 1) Field plowing: Use a tractor to beat the field soil to a homogeneous slurry, and then use a laser leveler to level the field soil on a horizontal line, so that the difference between the highest point and the lowest point of the field is within 2cm, and settle for 5 days after leveling. Sow when the soil is adjusted to allow ridges; Among them, in the process of field plowing, apply base fertilizer in the field, and the application amount is 9kg / 666.7m 2 Urea, 8kg / 666.7m 2 potassium oxide, 18kg / 666.7m 2 of phosphorus pentoxide;

[0036] 2) Seed treatment: dry the seeds in the sun for 3 days, then soak the seeds in a fungicide for 3 hours, then wash and accelerate germination, and urge the seeds until they are broken;

[0037] 3) Sowing: Before sowing, mix ...

Embodiment 2

[0052] Using the high-efficiency and precise water direct-seeding method of mid-season rice, the production of "Guangliangyou 476" was measured and planted in a certain area of ​​Jianli County, Hubei Province:

[0053] 1) Field plowing: Use a tractor to beat the field soil to a homogeneous slurry, and then use a laser leveler to level the field soil on a horizontal line, so that the difference between the highest point and the lowest point of the field is within 2cm, and settle for 4 days after leveling. Sow when the soil is adjusted to allow ridges; Among them, in the process of field plowing, apply base fertilizer in the field, and the application amount is 8kg / 666.7m 2 Urea, 8kg / 666.7m 2 potassium oxide, 18kg / 666.7m 2 of phosphorus pentoxide;

[0054] 2) Seed treatment: dry the seeds in the sun for 2 days, then soak the seeds in a fungicide for 3 hours, then wash and accelerate germination, and urge the seeds until they are broken;

[0055] 3) Sowing: Before sowing, mix ...

Abstract

The invention discloses a mechanical efficient and precise water direct sowing culture method for a middle-season rice. The method comprises the following steps of firstly using a tractor to beat a field soil into a homogenate shape, then using a laser leveler to level the field soil to one horizontal line, enabling the difference of the highest part and the lowest part of a field to be within 2 cm, settling for 3-5 days after leveling, sowing when the soil is regulated to form a ridge; drying the seeds in the sun for 2-3 days, soaking the seeds with a bactericide for 3-5 days, cleaning, and accelerating germination until the seeds germinate; using a rice precise direct sowing machine, applying atillering fertilizer when a rice seedling grows three leaves; applying an earring fertilizer when a plant grows to ear; and using a rice combine harvester to harvest when the rice is 100% yellow ripe. The investments of seedling raising cost and labor cost are directly reduced, the seedling raising cost of 50-100 yuan is saved for each 666.7 m<2>, 2-4 workers for raising seedlings are saved, and theseedling field of 66.7-132 m<2>is saved in every666.7 m<2>of the field compared with the transplanting rice.

Description

technical field [0001] The invention relates to the technical field of rice cultivation, in particular to a cultivation method for mechanically high-efficiency, accurate and quantitative live-seeding of mid-season rice. Background technique [0002] Rice is the main grain crop in my country, accounting for 30% of the country's grain planting area and 40% of the country's total grain output. With the development of modern agriculture and the increase of labor costs, rice production is gradually developing in the direction of lightness, simplification and high efficiency. Some studies believe that mechanized operations can increase rice production by 1000kg / hm compared with traditional manual operations. 2 , the increase rate is 5% to 10%, which has significant social and economic benefits. The current mechanical planting of rice mainly includes mechanical transplanting, mechanical throwing, and mechanical direct seeding, etc. The first two include the seedling raising stage....
