The invention discloses a seedling raising method for pigment marigold. The method comprises the following steps of: 1, strict seed treatment; 2, preparation of a nursery bed covering; 3, seedling raising in a shoot for cutting nursery; 4, management over the shoot for cutting nursery; and 5, cutting seedling raising in a cutting nursery. According to the method, the problem of climatic barriers to seedling raising nurseries in the construction of industrial development bases for the pigment marigold in two high mountain regions in the middle and upper reaches of the Yangtze River is solved, and in addition, the problem that the pigment marigold is excessively grown in a seedling stage, and the growth of seedlings is not required to be restrained after the seedlings are transplanted or that the seedlings are passively planted provisionally when the seedlings cannot be timely transplanted due to the climate is effectively solved; seedling cost is saved; the per unit area yield of flowers is improved, and an upside-down condition is effectively prevented; and pest and disease damage is remarkably alleviated.

The invention discloses a high-nitrogen composite fertilizer and a preparation method thereof. The preparation method comprises the following main steps: adding component raw materials namely potassium chloride, monoammonium phosphate, urea, ammonium bicarbonate, ammonium sulfate and calcium powder into a conveyor in a certain weight part for sufficiently and evenly mixing; breaking and mixing, and then successively carrying out pelleting, drying, cooling, secondary screening and coating; and finally, packaging to obtain a finished product. The preparation method disclosed by the invention is simple; the prepared high-nitrogen composite fertilizer can effectively provide lodging resistance, disease resistance and drought resistance for crops; and the absorption rate of the crop is high, and the damage on soil is also correspondingly retarded.

The invention discloses a drought resisting insecticide fertilizer specially used for corn and a preparation method thereof. The drought resisting insecticide fertilizer specially used for the corn is mainly obtained by mixing and fermenting raw materials in certain parts by weight, wherein the raw materials comprise poultry waste, szechwan Chinaberry fruit saw powder, poly(methylbenzene methacrylate), bean cake, humic acid, polyethylene glycol, calcium bicarbonate, ethyl acetate, ammonium phosphate, river sand, potassium chloride, sodium nitrate, yeast biologic fertilizer, palygorskite, trace element fertilizer, nitrogen-fixing bacteria fertilizer and bentonite. The preparation method is simple, the prepared drought resisting insecticide fertilizer specially used for the corn can effectively provide lodging resistance, disease resistance and drought resistance for the corn, absorption rate of the corn is high, utilization rate of the fertilizer is improved, and harm to soil is correspondingly reduced to some extent.

With currently commonly used agricultural composite fertilizers, nutrient elements are not comprehensive, and growth requirements of crops cannot be completely satisfied. The invention provides an organic-inorganic high-efficiency total-element fertilizer aiming at the defect. The fertilizer provided by the invention has the advantages that: with the total-effect fertilizer, soil quality can be effectively improved; soil performance can be improved, soil physical and chemical properties can be improved, soil nutrient conditions can be improved, and effectiveness can be improved. The fertilizer has main effects of soil microbial activity improving, soil enzyme activity improving, crop germination rate improving, crop resistance improving, and crop disease resistance improving. With the fertilizer, phenomena such as disease, drought and flood, lodging, rotten root, root burn, seedling burn, de-fertilization, fruit fertilizing, defoliation, yellow leaf, and dead leaf can be prevented, agricultural product nutritional value can be improved, agricultural product processing quality can be improved, crop yield can be improved, and crop quality can be ensured.

The invention provides paddy rice seedling culture soil containing chitosan. The paddy rice seedling culture soil is prepared from the following components by mixing: 10 parts of the chitosan, 30 parts of common soil, 30 parts of humic acid, 15 parts of attapulgite, 5 parts of a lumbrokinase stock solution, 2 parts of citric acid, 3 parts of calcium superphosphate, 2 parts of potassium sulfate and 3 parts of zinc sulfate. The paddy rice seedling culture soil containing the chitosan, provided by the invention, contains a large quantity of organic matters, macroelements and microelements, can meet nutrients needed by growth and development of paddy rice seedlings and has the effects of improving the quality of the seedlings and improving disease and insect resisting capabilities.

The invention provides a rice seedling culture fertilizer, which is prepared from 18 to 20g of chitin, 200 to 350g of total water soluble potassium fulvic acid, 80 to 150g of lumbrukinase stock solution, 20 to 50g of citric acid, 100 to 150g of superphosphate, 200 to 450g of monoammonium phosphate and 70 to 100g of zinc sulfate through uniform stirring. In the use process, the fertilizer and waterare diluted according to the ratio of 1:1000. A great number of organic matters, macro elements and trace elements are contained; the nutrients required by the growth and development period of rice seedling can be met; the effects of improving the seedling quality and improving the disease and insect pest resistance capability are achieved. The product is a whole water-soluble rice seedling fertilizer; in the use process, the fertilizer and water are diluted according to the proportion of 1:1000; after soil is laid on a seedling culture disc, the diluted seedling culture fertilizer is used for spraying and seeping the soil on the seedling culture disc; the complicated soil fertilizer mixing work is avoided; the operation is simple; the implementation is easy; wide prospects are realized in the rice seedling culture work.
