An organic rice production method comprises the following steps that a, previous preparation is conducted; b, rice seedlings are raised; c, an organic soil field is ploughed; d, rice seedling transplantation and water and fertilizer management after transplantation are conducted; e, rice is harvested. The organic rice production method solves the problems that as for organic rice production in the south, rice yields are low, and plant diseases and insect pests are serious, enriches profit chains of organic rice production, directly promotes development of the organic rice and soil fertility improvement to the organic production rice field of our country, and has wide application space in organic agricultural production.

The invention discloses a process method for extracting methanol and acetic acid during furfuraldehyde production. The process method comprises the following steps of: injecting a crude furfuraldehyde raw solution produced in a furfuraldehyde workshop into a reaction kettle; adding a catalyst and introducing steam to heat; conveying reactants in the reaction kettle into a separation tower, and separating; returning the crude furfuraldehyde separated at the bottom of the tower to the furfuraldehyde workshop, and performing rectification and dehydration to generate a furfuraldehyde product; conveying the mixed gas of methanol and acetic acid into a condenser from the top of the separation tower, and condensing; and conveying a mixed solution containing methanol and acetic acid into a separator, and separating. The process method disclosed by the invention is simple in process and less in investment; methanol and acetic acid are extracted by virtue of furfuraldehyde production wastewater, other raw materials are not required, and only are labour, electric charge, the catalyst and simple devices needed, thus solving the problem of waste of lots of resources caused by direct drainage and discard of the furfuraldehyde production wastewater, and solving the problem of increase of production cost caused by a high investment of environmental protection equipment for wastewater treatment; and in case of an annual output of 5000 tons of furfuraldehyde, 1000 tons of methanol and 2000 tons of acetic acid can be extracted, and net income can be increased by 4500 thousands yuan.

The invention discloses a method for planting dry-land Brassica napus by using mulching film corn residual films, which is characterized in that the residual films are reserved after mulching film corns are harvested, and the Brassica napus is dibbled by using broken films according to the original specifications, i.e. the ridge width being 1.0m to 1.2m and the ridge spacing being 0.3m to 0.5m, the row spacing being 20cm to 23cm, the plant spacing being 25cm to 30cm, 0.2kg to 0.3kg of seeds per mu land and 5 to 8 grains per pit; when 3 to 5 main leaves grow from the Brassica napus, final singling of seedlings is completed at one step, two seedlings per pit are left and the density is controlled to be 18000 to 20000 plants per mu; and when 6 to 8 main leaves grow from the Brassica napus, the residual films are uncovered, intertillage soil loosing is conducted in combination with application of 8kg to 10kg of urea to promote the seedlings and the soil among ridges is lifted up to the ridges for planting the Brassica napus. By reusing the residual films, the method effectively solves the problems of insufficient soil moisture, low ground temperature, uneven emerged seedlings, poor seedling growth and high field management labor input from the sowing to the stage of the dry-land Brassica napus with 8 main leaves, realizes the tillage-free and drought-resistant cultivation of the Brassica napus, and achieves the goals of cultivating strong seedlings, saving the cost and increasing the efficiency during Brassica napus production.
