Abstract

The invention provides a functional fertilizer for orchards in saline-alkali soil and a preparation method of the fertilizer, and relates to the field of fruit tree fertilizers. The fertilizer comprises the following components, in parts by weight: 10 to 15 parts of urea, 5 to 10 parts of diammonium phosphate, 8 to 12 parts of potassium sulfate, 4 to 6 parts of zinc sulfate, 3 to 5 parts of ethylenediamine tetraacetate chelated iron, 20 to 30 parts of fish meal, 40 to 50 parts of decomposed chicken manure, 1 to 3 parts of a microbial inoculant, 5 to 15 parts of polyvinyl alcohol microspheres,2 to 4 parts of humic acid, and 80 to 120 parts of modified bentonite. The functional fertilizer prepared by the method is particularly suitable for planting of fruit trees in the orchards in the saline-alkali soil, can not only improve the quality and yield of fruits and economic benefits, but also improve the soil environment, increase the content of organic matter, reduce salts, and effectivelyrealizes water and fertilizer retention.

Description

technical field [0001] The invention relates to the field of organic fertilizers, in particular to a functional fertilizer for saline-alkali land orchards and a preparation method thereof. Background technique [0002] Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. According to the incomplete statistics of UNESCO and FAO, the area of ​​saline-alkali land in the world is 954.38 million hectares, of which my country is the largest 99.13 million hectares. The formation of alkaline soil and alkalized soil in my country is mostly related to the accumulation of carbonate in the soil, so the degree of alkalization is generally high, and plants in severe saline-alkali soil areas can hardly survive. [0003] In the arid and semi-arid areas of Northeast, Northwest, and North China, the precipitation is small and the evaporation is large, so the salt dissolved in water tends to accumulate on the soi...
