Organic-inorganic coated fertilizer capable of improving sweetness of strawberry and preparation method thereof

Abstract

The invention discloses an organic-inorganic coated fertilizer capable of improving sweetness of strawberry and a preparation method thereof. The organic-inorganic coated fertilizer is prepared from the following raw materials in parts by weight: 43-47 parts of chicken manure, 14-17 parts of rice washing water, 34-37 parts of pine sawdust, 30-32 parts of chestnut shell, 3-4 parts of dolomite dust, 13-15 parts of carbonized straw, 14-19 parts of peat, 7-10 parts of urea, 15-19 parts of ammonium sulfate, 13-16 parts of potassium dihydrogen phosphate, 4-6 parts of potassium sulfate, 8-13 parts of methacrylate, 3-4 parts of mica powder, 1-2 parts of alum, 9-12 parts of fly ash, 5-8 parts of sodium carbonate, 2-4 parts of sticky sorghum powder, 1-3 parts of potato powder, 6-9 parts of an EM bacteria agent, 8-14 parts of a soil conditioner, and an appropriate amount of water. The organic-inorganic coated fertilizer disclosed by the invention is based on understanding of ingredients of soil and strawberry fertilizer characteristics, an organic fertilizer which is free of bacteria and pollution and favorable to the strawberry is prepared by a fermentation method, and according to nutrition proportion of the organic fertilizer, an inorganic fertilizer is added properly, so that the nutrition can be balanced, and yield increase of the strawberry can be ensured..

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to an organic-inorganic coated fertilizer for improving the sweetness of strawberries and a preparation method thereof. Background technique [0002] my country is a large agricultural country, mainly growing vegetables, rice and fruits, and only a small part is used for lawn and ornamental gardening. Chinese farmers have a fine tradition of using organic fertilizers, which have been able to maintain the fertility of the soil for thousands of years. However, relying solely on the material circulation within agriculture, it is difficult to rapidly and substantially increase crop yields to meet the growing population's needs for agricultural products. It is the application of chemical fertilizers that provides new sources of nutrients for crops and produces more agricultural products. "Fertilizer is the food of plants". The initial application of chemical fertilizers on the land has a sig...

Problems solved by technology

"Fertilizer is the food of plants". The initial application of chemical fertilizers on the land has a significant effect on increasing crop yields. Then people began to apply fertilizers blindly, but did not bring corresponding benefits. This is because the distribution of fertilizers is not reasonable enough and the supply is not timely enough. The application is not scientific enough, and with the development of high-concentration fertilizers, coupled with the leaching and erosion of these elements in the soil, some trace and medium nutrients ar
