Abstract

The invention discloses a yield-increasing water retention fertilizer special for hickory nuts. The fertilizer is prepared from, by weight, 50-150 parts of organic fertilizer, 5-15 parts of steel slag, 5-15 parts of urea, 15-25 parts of diammonium phosphate, 5-10 parts of ammonium bicarbonate, 3-15 parts of potassium sulfate, 2-10 parts of magnesium sulfate, 10-20 parts of calcium cyanamide, 3-10 parts of calcium sulfate, 1-10 parts of calcium oxide, 4-8 parts of microelements, 0.1-1 part of gamma-polyglutamic acid, 0.3-1.5 parts of vermiculite powder, 0.5-1.5 parts of bentonite, 5-15 parts of ardealite, 0.05-0.3 part of malic acid, 0.1-0.5 part of phosphate solubilizing bacteria, 0.5-3 parts of glucose, 2-5 parts of sodium potassium tartrate tetrahydrate, 2-5 parts of rare-earth salt and 1-5 parts of water-retaining agent. The yield-increasing water retention fertilizer special for the hickory nuts is reasonable in formula, comprehensive and balanced in nutrition, high in water retaining ability and capable of increasing the yield of the hickory nuts, improving quality and improving physical and chemical properties of soil.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special pecan fertilizer for increasing production and retaining water. Background technique [0002] In 1996, Ningguo City was awarded the "Hometown of Pecans in China". The hickory nuts it produces are large in size, thin in shell, thick in kernel, high in oil content, and good in marketability. The existing hickory cultivation area is 330,000 mu, with an output of about 9,500 tons in 2014 and a total industrial output value of 1 billion yuan. However, with the continuous growth of the pecan industry and the extensive use of chemical fertilizers by growers, ecological security problems in the pecan cultivation area of ​​Ningguo City have gradually emerged. It is more serious. The overall soil fertility of hickory stands shows a downward trend. Soil acidification and the influence of natural factors lead to the inhibition of hickory tree growth. Quality is also affected ...
