Embodiment 1
[0045] The invention provides a three-free planting method for wheat-oil interleaved rice, comprising the following steps:
[0046] (1) Wheat oil sowing: 1-15 days before rice harvest in autumn, no-tillage, direct seeding of wheat or rapeseed;
[0047] (2) Rice harvesting: mechanical harvesting of rice, stubble is left, and the straw is automatically chopped and evenly covered;
[0048] (3) Wheat oil growth: normal management during the wheat or rape growing season;
[0049] (4) 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;
[0050] (5) Tillering stage: establish a thin water layer of about 5 cm, and apply fertilizer twice;
[0051] (6) Jointing stage: In the early stage of jointing, short-term drainage, light open field, after rehydration, apply the third fertilizer, in the middle stage of jointing, moist irrigation;
[0052] (7) Heading stage: from the booting ...
Embodiment 2
[0061] Similar to Example 1, the difference between Example 2 and Example 1 is that the step (5) in Example 1 is changed to: (5) Tillering stage: by moving densely to fill in the gaps, it is guaranteed that no less than 30 plants per square meter For rice seedlings, keep a thin water layer and apply fertilizer twice;
[0062] Embodiment 2 of the present invention and traditional farming method, overall data contrast is as shown in table 2:
[0063] Table 2
[0064] traditional farming Example 2 Fertilization cost (yuan / mu) 150-200 100 Sowing cost (yuan / mu) 50 0 Cultivated land cost (yuan / mu) 100-150 0 Transplanting cost (yuan / mu) 150 0 Yield (kg / mu) 500-650 530-720
[0065] It can be seen from Table 2 that in Example 2 of the present invention, no sowing, no tillage, and no transplanting can save the cost of 300-400 yuan per mu of rice. In addition, returning straw to the field and applying less chemical fertilizers can save...
Embodiment 3
[0067] The invention provides a three-free planting method for wheat-oil interleaved rice, comprising the following steps:
[0068] (1) Wheat oil sowing: 1-15 days before the harvest of edible weedy rice in autumn, no tillage, direct seeding of wheat or rapeseed;
[0069] (2) Rice harvesting: Mechanical harvesting of edible weedy rice, leaving stubble, and automatically chopping and evenly covering the straw;
[0070] (3) Wheat oil growth: normal management during the wheat or rape growing season;
[0071] (4) 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;
[0072] (5) Tillering stage: uniform seedlings, ensure that the plant density of edible weedy rice is 15-100 plants / square meter, keep a thin water layer, and apply fertilizer twice;
[0073] (6) Jointing stage: In the early stage of jointing, short-term drainage, light open field, after rehydration, apply the t...
