The invention discloses a transplantation method for accelerating the growth and the development of a faint scent type tobacco plant, and belongs to the technical field of tobacco plant cultivation. The method comprises the following steps of land preparation, ridging, transplanting, seedling leading and film uncovering. Firstly, deep ploughing and land preparation are carried out, 1600-2400kg / mu of decomposed fertilizer is applied; then, ridging is carried out according to the line spacing of 100-120cm with the ridge height of 20-30cm and the ridge bottom width of 75-95cm; the double-line application of 16-24kg / mu of compound fertilizer, 35-45kg / mu of phosphate fertilizer, 12-20kg / mu of potassium sulphate, 1-2kg / mu of zinc sulfate and 15-25kg / mu of cake fertilizer is carried out during ridging; the tobacco seedling transplantation period is from later January to the medium May, punching is carried out according to the row spacing of 45-55cm with the hole width of 10-15cm and the depth of 15-20cm; before transplantation, 4-6kg / mu of compound fertilizer and 3-5kg / mu of potassium sulphate are subjected to hole application; after transplantation, 2-3kg of Dinggen water is poured, a mulching film is covered, and the distance between the top of the tobacco seedling to the mulching film is 10-15cm; when the top of the tobacco seedling supports the film after transplantation is carried out for 15-25 days, the seedling is led to cover soil and seal a dibble; and when the tobacco seedling enters the bloom growing period after transplantation is carried out for 30-40 days, earthing, weeding and watering are carried out. According to the method, the growth and the development of the tobacco seedling can be accelerated, the biomass accumulation is increased, the tobacco yield and quality can be improved, the faint scent flavor of the tobacco is reinforced, and the tobacco seedling illness catching rate is lowered.

The invention discloses a special selenium-enriched organic fertilizer for grapes, and a preparation technology of the special selenium-enriched organic fertilizer. The preparation technology comprises the following steps of treating green manure, poultry and livestock excrement, a humic acid type fertilizer and peanut shells to obtain treated materials, performing fermentation for the first time on the treated materials and plant ash, then adding calcium superphosphate, urea, potassium dihydrogen phosphate and selenium salt, and performing mixed fermentation so as to obtain the special selenium-enriched organic fertilizer for grapes. According to the special selenium-enriched organic fertilizer for the grapes provided by the invention, the fertilizer retention capacity and the water storage capacity of soil can be effectively improved, decomposition and conversion of organic matters are facilitated, the nutrient elements are rich, the yield of grapes is improved, a few nutrients of the organic fertilizer run off, the content of selenium elements in the grapes is 10-20% greater than that of general grapes, and the incidence of diseases and insect pests of the grapes is low; and besides, through the preparation technology disclosed by the invention, worm's ova, pathogenic bacteria and the like in raw materials can be effectively killed, besides, the method is simple, and the preparation process is convenient to operate.

The invention discloses a planting method of pollution-free tomatoes. The planting method mainly comprises the following steps of: preparing a base material, immersing seeds, sowing the seeds, carrying out seedling stage management, carrying out field management, and harvesting and picking. Compared with an existing tomato planting technology, the planting method has extremely remarkable advantages; the tomatoes are planted by adopting the technical scheme and the planting method is green, environmentally friendly and pollution-free; the yield of the tomatoes is extremely improved; the seedling stage management is carried out so that the content of calcium, magnesium, iron and zinc in the harvested tomatoes is improved by 9%-13% when compared with that in tomatoes which are commonly planted and harvested; continuous five years of planting experiments are counted up to show that the yield of the tomatoes planted by the method is improved by 15%-17% when compared with that of the tomatoes which are planted by a common method.

The invention discloses a method for planting a rare medicinal material Dendrobium officinale, and belongs to the field of technologies for planting Dendrobium. The method includes steps of (1), carrying out pre-planting preparation; (2), applying base fertilizers, to be more specific, mixing culture substrates and the base fertilizers with one another according to a proportion of 10:1; (3), carrying out transplanting and colonization management; (4), carrying out management in growth periods. The base fertilizers are made from, by weight, 40-50 parts of human excrement and urine, 40-45 parts of livestock and poultry manure, 10-15 parts of earthworm cast, 17-20 parts of bone meal, 25-30 parts of egg shells, 10-14 parts of thoroughly decomposed biogas residues, 8-10 parts of traditional Chinese medicine residues, 18-22 parts of plant ash, 5-8 parts of distillers' grains and 0.2-1 part of trace element fertilizers. The method has the advantages that the Dendrobium officinale planted by the aid of the method is high in survival rate, yield and nutrient component content and medical value, has few diseases and low insect pest occurrence, and can grow fast.

The invention discloses a special controlled-release insecticide fertilizer for sugarcanes. The special controlled-release insecticide fertilizer is prepared from the following substances in parts by weight: 40-60 parts of a main fertilizer, 0.5-1.5 parts of a microelement fertilizer, 2-5 parts of an antibacterial agent, 3-6 parts of an insecticide, 2-4 parts of a controlled-release agent and 20-30 parts of a filling agent. The controlled-release insecticide fertilizer disclosed by the invention comprehensively shows a continuous high-quality fertilizer effect and favorable pest preventing and controlling effects and can be used for increasing the yield of sugarcane stalks by 20-30% as comparison with a common fertilizer, the comprehensive pest occurrence rate is reduced by 30-40%, all the components can be naturally degraded in soil, soil hardening and other phenomena cannot be generated if the special controlled-release insecticide fertilizer is used for a long term, and the special controlled-release insecticide fertilizer has a favorable application prospect.
