Apple tree planting controlled-release fertilizer and preparation method thereof

Abstract

The invention relates to an apple tree planting controlled-release fertilizer. The invention is characterized in that the fertilizer is prepared from the following raw materials in parts by weight: 40-45 parts of dried leaf, 20-24 parts of wormcast, 50-65 parts of castor cake, 30-34 parts of bagasse, 30-40 parts of rice washing water, 15-20 parts of shell powder, 2-3 parts of EM (effective microorganism) microbial inoculant, 8-10 parts of vermiculite powder, 7-9 parts of potassium dihydrogen phosphate, 8-10 parts of potassium chloride, 4-5 parts of magnesium sulfate, 5-6 parts of calcium chloride, 2-3 parts of calcium superphosphate, 7-10 parts of ammonium bicarbonate, 8-12 parts of alkyd resin, 2-3 parts of propanol, 3-4 parts of sodium dodecyl benzene sulfonate, 4-5 parts of crosslinking agent and a proper amount of water. According to the research into the apple tree planting, a proper crosslinking agent is added into the alkyd resin to prepare the resin-type fertilizer with slow-release effect; the resin can be degraded and slow the release of NPK, thereby increasing the utilization ratio of the fertilizer; the resin has the function of adsorbing moisture, and thus, the fertilizer is especially suitable for retain and control the moisture in the hillside planting of apples and the like; by using the fertilizer, the use of the supplementary fertilizer is reduced, the domestic waste energy can be recycled, the pollution is reduced, the planted fruit is more healthy, and the fertilizer application is reduced; and the labor can extra work load can be lowered in the aspect of watering, thereby promoting the economic growth from another perspective.

Description

technical field [0001] The invention relates to an apple tree planting controlled-release fertilizer and a preparation method thereof, belonging to the technical field of apple planting controlled-release fertilizer in fertilizers. Background technique [0002] Chemical fertilizer is the largest material input in agricultural production. According to the statistics of the Food and Agriculture Organization of the United Nations, chemical fertilizers account for 40-60% of the increase in yield. However, the production time shows that due to the nature of the fertilizer itself and the soil Due to the impact of environmental conditions and agricultural measures, the utilization rate of chemical fertilizers is very low. The waste of nutrient resources caused by the low utilization rate of fertilizer nutrients in China is astonishing. According to statistics, the annual production and application of nitrogen fertilizer in China is about 20 million tons, and the seasonal utilizatio...
