Problems solved by technology

[0004] The main hazards of weedy rice are low yield, poor appetite, early seedling emergence and strong tillering per plant. Once weedy rice is mixed in the paddy field, conventional rice seedlings will be bullied. If weedy rice is not removed in time, it will directly affect Field rice production

Embodiment 1

[0043] A planting method of edible weedy rice, comprising the following steps:

[0044] (1) Paddy field management in the previous year: During the rice growth period, the naturally occurring weedy rice plants are kept and managed in the normal field;

[0045] (2) Wheat and oil sowing: no-tillage, live wheat or rape seeds;

[0046] (3) Rice harvesting: mechanical harvesting of rice, allowing the weedy rice seeds to fall naturally;

[0047] (4) Wheat oil growth: normal management during the wheat or rape growing season;

[0048] (5) Harvesting of wheat oil: harvesting of wheat or rapeseed, leaving stubble;

[0049] (6) Growth of weedy rice: During the growing season of weedy rice, the plants of weedy rice are reserved, managed in the normal field, and harvested normally.

[0050] Embodiment 1 of the present invention and conventional rice, comprehensive data comparison is as shown in table 1:

Embodiment 2

[0055] A planting method of edible weedy rice, comprising the following steps:

[0056] (1) Paddy field management in the previous year: During the rice growth period, the naturally occurring weedy rice plants are kept and managed in the normal field;

[0057] (2) Wheat and oil sowing: 1-15 days before rice harvest in autumn, no tillage, live wheat or rape seeds;

[0058] (3) Rice harvesting: mechanical harvesting of rice, let the weedy rice seeds fall to the ground naturally, leave stubble, chop the straw and cover it evenly;

[0059] (4) Wheat oil growth: normal management during the wheat or rape growing season;

[0060] (5) Harvesting of wheat oil: After wheat or rape is harvested, after 5-7 days of irrigation and humidity in the field, a thin water layer of 3-5cm is established;

[0061] (6) Tillering stage: keep a thin water layer and apply fertilizer for the first time;

[0062](7) Jointing stage: In the early stage of jointing, short-term drainage, light open field,...

Embodiment 3

[0072] A planting method of edible weedy rice, comprising the following steps:

[0073] (1) Paddy field management in the previous year: During the rice growth period, the naturally occurring weedy rice plants are kept and managed in the normal field;

[0074] (2) Wheat and oil sowing: 1-15 days before rice harvest in autumn, no tillage, live wheat or rape seeds;

[0075] (3) Rice harvesting: mechanical harvesting of rice, stubble, chopped straw and even coverage;

[0076] (4) Wheat oil growth: normal management during the wheat or rape growing season;

[0077] (5) Harvesting of wheat oil: After wheat or rape is harvested, after 5-7 days of irrigation and humidity in the field, a thin water layer of 3-5cm is established;

[0078] (6) Tillering stage: keep a thin water layer, put 20-50 ducklings / mu into the paddy field, and supplement organic fertilizer;

[0079] (7) Jointing stage: maintain a thin water layer;

[0080] (8) Heading stage: take out the ducks in the paddy fie...

Abstract

The invention provides a method for planting edible weedy rice. New uses of weedy rice are creatively developed, and the method for planting the weedy rice is provided. The falling-on-soil ability ofthe weedy rice after maturity is high, no-tillage and mechanical harvesting of rice are used to enable seeds of the weedy rice to fall to the soil, the weedy rice has high stress resistance and environmental adaptability, even in poor conditions, the weedy rice can grow tenaciously, the falling off of the grains of the weedy rice caused by mechanical harvest of a previous season of rice might cause uneven emergence of the weed rice in the season, and a method of removing seedings from dense area to sparse area can be used, so that the yield of the edible weedy rice is increased; the yield of the edible weedy rice is low, the value is high, the economic benefit is good, combined with a straw turnover and rice-duck co-cultivation technology, the yield of the edible weedy rice can be furtherincreased, the production cost is reduced, and the profit is increased.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for planting edible weedy rice. Background technique [0002] Weedy rice is derived from a special type of rice material produced by the natural cross-pollination of cultivated rice and wild rice or indica rice and japonica rice, which is wild in the natural environment. It has strong stress resistance and adaptability to the environment. During the growth of rice, it competes with cultivated rice for sunlight, nutrients, and water. To be precise, it has the characteristics of weeds, so it is called weedy rice. [0003] Weedy rice has caused harm to the paddy fields of more than 50 countries around the world, especially the fields of no-tillage and less-tillage direct-seeding. The damage has been serious in Southeast Asian countries such as Thailand, Vietnam, and Malaysia, and has attracted great attention from the Food and Agriculture Organization of the U...
