Embodiment Construction

[0027] The preparation work includes the previous field and the selection of improved varieties:

[0028] The requirements of the previous field are that the wheat field interlaced with rice can be irrigated and drained in time, and the field surface is flat. Conscientiously control the weeds in the previous stubble, and disable chlorsulfuron and metsulfuron herbicides in wheat fields to avoid damage to the interplanted rice seedlings. Every 2.5-3 meters in the paddy field, a 30-centimeter-wide and 10-15-centimeter-deep ditch is opened, and the soil is cultivated on the ridges on both sides to ensure irrigation and drainage. Leaves of weeds to facilitate seeds landing on the ground. After the wheat turns green, apply a no-deep tillage soil conditioner to loosen the soil.

[0029] The requirements for the selection of improved varieties are that rice varieties with strong tillering ability, well-developed root system, suitable growth period, large panicle shape, disease resis...

Abstract

The invention relates to the technical field of agriculture planting, and discloses a method for inter-planting rice in wheat field with ultra-high stubble. The method comprises the steps that in the middle-late grain-filling stage of wheat, treated rice seeds are sown on the surface of the wheat field in a broadcast mode, when the wheat is harvested, about 30 cm of high stubble is reserved, and after the wheat is subjected to threshing, straw is scattered on the spot or buried into dead furrows nearby; the method further comprises the step of field management of wheat harvest, such as water management, fertilizer management, chemical weed control and disease and insect control. By means of the method, all wheat straw returning is achieved, soil can be improved, agricultural sustainable development can be promoted, and the situations that farmers burn the straw in the open air and environments are polluted are avoided; besides, the land does not need to be cultivated and no machines are needed to transplant rice seedlings so that the fuel consumption of the machines can be reduced; compared with common rice direct sowing, the cultivated land is saved.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for interplanting rice in a super-high-stubble wheat field. Background technique [0002] Rice is a staple food that people love, and nearly half of the world's population depends on rice. Due to the high and stable yield of rice, the perennial rice planting area in my country is about 450 million mu. Planting rice can relieve the population's pressure on the land and the demand for food. my country is a large agricultural country with a large population but little arable land. To solve the problem of food and clothing for the people of the whole country, we must constantly [0003] Increase crop yield per unit area. Rice planting methods are generally divided into transplanting, throwing and direct seeding. Transplanting is divided into manual transplanting and mechanical transplanting. Manual transplanting is labor-intensive and requires a large amount ...
