The invention belongs to the field of multifunctional novel biofertilizers, and relates to a special plant-derived liquid pesticide fertilizer for vegetables, which can be used through spraying, sprinkling and water dissolving. The pesticide fertilizer comprises the following raw materials in parts by weight: 3-9 parts of elm bark, 1-5 parts of elm seed, 3-7 parts of sophora bark, 1-7 parts of sophora flower, 1-5 parts of honeysuckle flower, 1-3 parts of white sugar, 1-8 parts of agricultural amino acid, 2-9 parts of potassium dihydrogen phosphate, 5-9 parts of urea, 0.1-3 parts of amino-oligosaccharin, 0.01-0.5 part of polyglutamic acid, 0.01-0.1 part of lecithin and a proper amount of water. According to the invention, the prepared special plant-derived liquid pesticide fertilizer for vegetables has no toxicity, no pollution and no public nuisance, is especially suitable for development of green agriculture, ensures that the produced vegetables conform to the requirements of green foods and agriculturally has the characteristics of no residue, no pollution and no resistance; and by regulating endogenous hormones of vegetables, the special plant-derived liquid pesticide fertilizer for vegetables achieves the purposes of improving the vegetable quality and realizing high yield and good harvest.

The invention belongs to the field of multifunctional novel bio-fertilizers and relates to a special plant source liquid medicinal fertilizer for melons and fruits. The fertilizer is prepared from the following raw materials in parts by weight: 2-9 parts of honeysuckles, 2-10 parts of mint, 1-7 parts of pseudo-ginseng, 7-20 parts of fulvic acid, 2-9 parts of brown sugar, 1-9 parts of amino-oligosaccharin, 2-9 parts of zinc sulfate, 2-7 parts of monopotassium phosphate, 20-70 parts of urea, 3-9 parts of boric acid, 0.01-0.1 part of lecithin and a proper amount of water. The plant source liquid medicinal fertilizer for melons and fruits prepared by the method provided by the invention is free from toxicity, pollution and public nuisance and is especially suitable for developing green agriculture, so that produced melons and fruits and the like meet the requirements of green food. The fertilizer has the characteristics of no residues, no pollution and no resistance agriculturally. The purposes of improving the quality of melons and fruits and enriching output and harvest are realized by virtue of adjusting endogenous hormones of melons and fruits.

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 ridging method for greenhouse cucumber cultivation without continuous cropping obstacles. The ridging method comprises the following steps of: 1) preparing a low plot, and laying a pesticidal geotextile on the surface of the plot, wherein the pesticidal geotextile consists of a lower geotextile which is treated with 8 to 12-mass-percent trisodium phosphate aqueous solution and 40 to 60-mass-percent N-2-benzimidazole-methyl carbamate powder and an upper geotextile which is treated with 0.2-mass-percent copper hydroxide aqueous solution; 2) spreading straw on the pesticidal geotextile, wherein the straw layer consists of straw wetted by water and a straw zymophyte agent and calcium superphosphate which contact the straw; 3) applying urea on the straw layer, and covering planting soil for fermentation; and 4) preparing plot surface and thus, preparing plot for cultivating cucumbers in a greenhouse. According to the ridging method, CO2 and small molecular substances generated straw yeasts are fully utilized, so compared with the ordinary cultivation method, the ridging method has the advantages that: the yield of the cucumbers is improved by about 11 percent; and the cucumbers are sweet and crisp.

The invention relates to a method for fertilizing winter wheat by the mixed basal application of a nitrogen fertilizer and maize straw. The method comprises the following steps of: (1) crushing summer maize straw in fields, returning to the fields completely, and spraying a nitrogen fertilizer solution on the surface of the crushed maize straw uniformly; (2) performing rotary tillage or ploughing; (3) sowing the winter wheat, and applying a phosphorus fertilizer, a potash fertilizer and a trace element fertilizer in a seed manure application mode; and (4) dressing the nitrogen fertilizer onceat the elongation stage of the winter wheat. According to the method, by a field returning mode of spraying the nitrogen fertilizer on the surface of the maize straw, a carbon nitrogen ratio of the straw is regulated, and the nutritional environment which facilitates the growth of straw decomposition microbes is constructed, so that the growth of the microbes is facilitated, the decomposition speed of the straw is improved, inorganic nitrogen of the fertilizer is converted into organic nitrogen, the loss of the nitrogen fertilizer is reduced, and the fertilizer efficiency of the nitrogen fertilizer is improved; and at the middle and late growth stage of the wheat, the amount of the organic nitrogen released by mineralizing the maize straw through the microbes is gradually increased, so that the growth requirement of the wheat at the middle and late growth stage on a nitrogen element is met.

The invention provides an integral pretreatment device for leachate in a waste incineration power plant. The device is arranged before rear-end biochemical treatment, has the characteristics of capability of efficiently degrading organic macromolecules, adjusting the carbon-nitrogen ratio and improving the biodegradability of the leachate, and is low in land cost due to small occupied area. The device comprises a shell and is characterized in that the shell is vertically arranged; an aeration dosing silt removal region, a mud-water separation region, an ammonia nitrogen blowoff region and a waste gas collection region are arranged in the shell in sequence from bottom to top; a mixed reaction cavity is formed in the top of one side of the shell; a water-passing hole is formed in the side wall, in the ammonia nitrogen blowoff region, at the upper part of the shell; the water-passing hole is communicated with the mixed reaction cavity in the outer side; an electrolysis and micro-electrolysis mixed reactor is arranged in the mixed reaction cavity; a doser is also arranged in the mixed reaction cavity; a three-phase separator is arranged in the mud-water separation region.
