Cultivation method of rice and wheat stalks returning to the field in full amount continuously and machine-transplanted seedlings for early living and early tillering

Abstract

The invention discloses a method for continuously returning full amount of rice and wheat stalks to the field and planting machine-transplanted seedlings for early tillering. ⑷Appropriately reduce the depth of plowing; ⑸Shallow planting of small plants in foot holes; ⑹Live trees without water layer; fertilizer; ⑾moist irrigation throughout. The invention solves the common problems that the total amount of straw in the soil and the decomposing intensity are significantly increased when the rice and wheat straws are continuously returned to the field, the time for machine-transplanted rice to turn green and live is generally prolonged, and even the dead seedlings are seriously dead, the number of ears is insufficient, and the ear shape is small. To solve the technical problems, a cultivation technology plan to ensure early germination and high yield of machine-transplanted seedlings was proposed, which is suitable for the northern area of ​​Jiangsu Province and similar areas.

Description

technical field [0001] The invention relates to the technical field of seedling cultivation, in particular to a cultivation method for rice and wheat stalks that are continuously and fully returned to the field and machine-transplanted for early tillering. Background technique [0002] The continuous and full amount of rice straw returning to the field can fertilize the soil, improve the physical and chemical properties of the soil, and increase the productivity of the cultivated land. At the same time, in order to strictly implement the "double ban" policy of the Jiangsu Provincial Government (no burning and throwing of crop straw), strengthen the rational use of rice straw resources and protect the ecological environment, governments at all levels in northern Jiangsu are currently vigorously promoting the full return of rice straw to the field .

Problems solved by technology

[0011] However, because the annual average temperature in northern Jiangsu is above 14°C, the annual rainfall is about 850-950mm, the three seasons of autumn, winter and spring are dry and rainless all year round, and the groundwater level is only 0.5-2.0m, resulting in the rice straw buried and returned to the field after a wheat growing season. 30-50% has not been decomposed, which not only significantly increases the total amount of straw in the initial soil of the paddy field, but also significantly increases the strength of straw decomposition, which can easily lead to severe poisoning-type stiff seedlings and significant yield reduction in machine-transplanted seedlings.
