Embodiment Construction

[0018] Specific examples of the present invention are given below to further illustrate the composition of the present invention.

[0019] A method for returning wheat straw to the field and no-tillage rice sowing of the present invention comprises the following process steps:

[0020] In step a, 3 days before the wheat harvest, the rice seed soaking agent is used for soaking the rice seeds, and the soaking time is 48 hours;

[0021] Step b, drying the soaked rice seeds;

[0022] Step c, spreading the dried rice seeds into the wheat field one day to several hours before wheat harvest;

[0023] In step d, after the wheat is harvested, the wheat stalks are artificially dispersed, and then poured with racing water;

[0024] Step e, after watering for 1-2 days, when there is no stagnant water in the field, spray the paddy field herbicide, and the paddy field herbicide is a conventional herbicide;

[0025] Step f, after the paddy rice grows to 2-3 leaves, topdress the special fe...

Abstract

The invention belongs to the technical field of agriculture, and particularly relates to a wheat straw returning and rice no-tillage seeding method. The wheat straw returning and rice no-tillage seeding method comprises the following technological steps: step a, carrying out pharmaceutical seed soaking on rice seed three days before harvesting wheat, wherein the soaking time is 48 hours; step b, airing the soaked rice seeds; step c, sowing the aired rice seeds into a wheat field one day or several hours before harvesting the wheat; step d, after harvesting the wheat, uniformly sowing wheat straw through manual assistance, then irrigating water in a way of draining while irrigating; step e, after irrigating for 1 to 2 days, spraying a paddy field herbicide when no water is remained in the rice field; step f, dressing fertilizer special for paddy rice after 2 to 3 leaves are grown in the paddy rice; step g, enabling other water and fertilizer management and disease and pest prevention and treatment to be consistent with rice seedling transplanting cultivation. The wheat straw returning and rice no-tillage seeding method disclosed by the invention has the beneficial effects that the fertility situation of soil can be improved, the plant height can be reduced, the lodging resistance of the paddy rice can be increased, the setting percentage can be increased, the production cost canbe remarkably reduced, and the economic benefit can be increased.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and in particular relates to a method for returning wheat straw to the field and no-tillage rice sowing. Background technique [0002] In my country's wheat and rice double-cropping areas, the wheat harvest season is tight, and at the same time, returning wheat straw as a paddy and dry rotation crop brings many difficulties to rice field preparation and transplanting. Therefore, it is difficult to use wheat straw. Wheat stubble rice has to go through so many links from raising seedlings to transplanting. In addition to the normal costs of seeds, fertilizers and chemical weeding, other production costs include rice seedling raising, wheat straw cleaning (including straw bundling and handling) , wheat field plowing, paddy field tidying and transplanting generally cost about 700 yuan per mu; more importantly, after the wheat is harvested, the wheat straw cannot be returned to the field and it ...
