Efficient organic nano-carbon compound slow/controlled release fertilizer special for blueberries and preparation method for slow/controlled release fertilizer

Abstract

The invention discloses an efficient organic nano-carbon compound slow / controlled release fertilizer special for blueberries. The slow / controlled release fertilizer is prepared from the following raw materials in parts by weight: 8 to 14 parts of methyl cellulose, 0.5 to 1.0 part of polyethylene glycol, 4 to 6 parts of bentonite, 3 to 5 parts of attapulgite, 45 to 47 parts of wheat bran, 7 to 9 parts of brown sugar, 30 to 37 parts of wood chips, 0.01 to 0.03 part of chlormequat, 40 to 45 parts of earthworms, 12 to 14 parts of urea, 1 to 2 parts of manganese sulfate, 8 to 13 parts of potassium sulfate, 5 to 7 parts of nano-carbon powder, 12 to 17 parts of phosphorus gypsum, 8 to 13 parts of an EM microbial agent, 11 to 14 parts of a soil conditioner and a proper amount of water. The prepared fertilizer is high in fertilizer efficiency, and has the effects of activating soil, improving soil fertility, reducing soil and water loss and loosening the soil, and the ecological environment is protected.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a special nano-carbon high-efficiency organic composite slow-controlled release fertilizer for blueberries and a preparation method thereof. Background technique [0002] Chemical fertilizers play an important role in agricultural production. According to authoritative estimates, 55% of the increase in food production in developing countries is due to the effect of fertilizers. However, the utilization rate of chemical fertilizers is generally low. After ordinary fertilizers are applied to cultivated land, some Part of transpiration, dissipation and water loss is fixed and utilized by soil and soil microorganisms, and only part of it is absorbed and utilized by crops. Research shows that the utilization rate of urea and ammonium bicarbonate is 20% to 46%, phosphate fertilizer (diammonium, monoammonium, heavy calcium) is 10% to 25%, and potash fertilizer is 45% to 60%. It can be seen t...

Problems solved by technology

It can be seen that the utilization rate of ordinary fertilizers is very low

As a large agricultural country, China invests an astonishing amount of fertilizer every year, but the low utilization rate not only causes a huge waste of resources, but also causes serious environmental pollution. The excessive use of chemical fertilizers in my country's farmland has caused serious pollution, and eventually land production has been reduced. even extinct

So this requires people to fertilize several times in the whole growth process of the crops to meet the nutrient requirements of the crops during the growth period. However, repeated fertilization is not only a waste of labor, but also some large-scale fertilization uses machines, which will inevitably cause problems. Some external damage to crops
