Problems solved by technology

Xylitol slag is solid waste after extracting xylitol, plant ash is waste from biological power plants, and wheat straw is leftovers after harvesting wheat. These solid wastes contain more organic fertilizers and trace elements and are rich in sources. It is difficult to be absorbed and utilized by crops directly returning to the field

Abstract

The invention discloses a special organic fertilizer for greenhouse vegetables and a preparation method thereof. The special organic fertilizer for the greenhouse vegetables is prepared by carrying out piling fermentation on the following raw material in parts by weight: 800-1000 parts of xylitol residue, 200-300 parts of plant ash, 200-300 parts of wheat straw, 80-100 parts of soybean residue, 25-30 parts of urea, 6-10 parts of monopotassium phosphate and 4-6 parts of magnesium sulfate heptahydrate. The organic fertilizer has the advantages that a rapid rotting agent is not adopted, the costis reduced, labor and time are saved; according to the fertilizer enjoying characteristics of vegetables and soil characteristics as well as nutrition contents of various organic matters, different organic raw materials are selected and blended so as to form the organic fertilizer, thus the organic fertilizer has strong pertinence; the organic fertilizer does not contain harmful substances, is environmentally-friendly and is safe for vegetables; compared with the common fertilizer the applying amount of which is the same as that of the organic fertilizer, the yield of the vegetable applied with the special organic fertilizer for the greenhouse vegetables is improved by above 7%, and simultaneously, the quality of the vegetables is improved, and the commodity performance of the vegetables is good; and the organic fertilizer can be used for various vegetables in a winner warm type greenhouse, an early spring type large arch shed, a small arch shed and dry land.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, in particular to a special organic fertilizer for greenhouse vegetables and a preparation method thereof. Background technique [0002] Since the 1980s, off-season vegetables in protected greenhouses have gradually become an indispensable food for ordinary people in winter and spring. However, for a long time, excessive application of chemical fertilizers and organic fertilizers without harmless treatment have caused serious damage to the soil in greenhouses. The imbalance of acidity and alkalinity, excessive accumulation of salt, and aggravation of pests and diseases seriously affect the yield and quality of vegetables, and pose a great threat to human health. Therefore, soil restoration in greenhouses is imperative, and the application of non-toxic, non-polluting and environmentally friendly organic fertilizers is the key to solving the above problems. [0003] With the rapid d...
