Example Embodiment

[0069] Example 1

[0070] A method for cultivating rice based on rice-rice-oil three-ripening system, comprising the following steps:

[0071] (1) Excavation of box ditches in rapeseed season: after the harvest of late rice in the first year and before rapeseed transplanting or direct seeding, the fields are organized into a box surface with a width of 200-800cm; a box ditch is opened between adjacent two boxes, and the width of the box ditch is wide. 30-40cm, the box ditch is 45-60cm deep; rapeseed is planted on the box surface;

[0072] (2) Direct seeding of early rice while rapeseed is harvested: do not plow, apply herbicides, soak field water, or rotate tillage before planting early rice in the second year, keep the field surface dry, and turn on the weeding mode of the rapeseed harvester to control rapeseed After harvesting, the height of the stubble is about 30 cm. When the rapeseed is harvested, two wheeled semi-automatic strip direct seeding machines added behind th...

Abstract

The invention discloses a rice cultivation method based on a rice-rice-oil triple cropping system. The method comprises the following steps of not performing ploughing, not applying herbicides, not irrigating field soaking water, not performing rotary tillage before planting of next crop, keeping a field surface dry, performing harvesting and crushing on a previous crop to obtain crushed straws ofthe previous crop, and leaving stubbles of the previous crop after harvesting; pressing down stubbles of the previous crop, and carrying out seed sowing of the next crop; and after stubbles of previous crop are rebounded, enabling the crushed straw of previous crop to cover on stubble surface of previous crop. According to the method, the soil plough layer structure is changed, a straw layer, a seed fertilizer layer and a soil layer are formed from top to bottom, full-amount returning of the crop straw is achieved at a time, the straw is converted into a covering object, seeds and fertilizerare covered, and the covering object is used for covering the seeds and the fertilizer. The fertilizer utilization efficiency is favorably improved, and the optimal coupling of crop straw treatment, mechanical production and crop growth is realized. Chopped straw is arranged above the seeds to serve as a protective layer, so that sun protection, rain erosion prevention and bird damage prevention are achieved.

Description

technical field [0001] The invention relates to the field of cultivation technology, in particular to a rice cultivation method based on rice-rice-oil three-ripening system. Background technique [0002] According to statistics, the total national grain output in 2018 was 657.89 million tons, estimated based on the grain-to-stalk ratio of 1:1.2, plus other crop stalks, the country’s annual production of stalks exceeds 800 million tons, which contain a large amount of organic matter, nitrogen and phosphorus Potassium and trace elements, the nutrient content of nitrogen, phosphorus and potassium in 720 million tons of stems is equivalent to 6.4 million tons of urea, 9.3 million tons of superphosphate, and 9.3 million tons of potassium sulfate. [0003] Experiments have proved that returning crop stalks to the field by pressing or covering them is an effective measure to increase yield by more than 10%. However, crop stalk resources in our country become the bottleneck of the n...
