Problems solved by technology

Although the above-mentioned fertilizers are highly targeted, they can increase the yield of dried hickory nuts and will not cause waste of fertilizers, but the fertilizers are inorganic fertilizers, which can also easily cause soil acidification to intensify, soil nutrient supply imbalance, and have no effect on soil improvement. , and the effect of increasing production still needs to be improved

Abstract

A disclosed organic-inorganic compound fertilizer special for carya cathayensis comprises an organic fertilizer and an inorganic fertilizer; in the organic-inorganic compound fertilizer, the organic matter content is 20-25%, and the ratio of N element weight, P element weight in terms of P2O5 and K element weight in terms of K2O is 12-15:3-4:10-12; and the pH value of the organic-inorganic compound fertilizer is 6.5-8. The organic-inorganic compound fertilizer with appropriate usage amount is employed for normally-grown mature carya cathayensis. The compound fertilizer is added with a decomposed organic fertilizer prepared by taking pig manure as a raw material and plant ash prepared by taking rice chaff as a raw material through combustion, and also is added with a trace element fertilizer with a proper ratio, so that the organic-inorganic compound fertilizer is capable of substantially improving the yield of carya cathayensis, and also is capable of improving the acidifying statue of soil.

Description

technical field [0001] The invention relates to the field of fertilizer formulations, in particular to a special organic-inorganic compound fertilizer for pecans. Background technique [0002] Carya is a worldwide dry fruit, belonging to Juglandaceae (Juglandaceae) Carya (Carya), and there are 18 species in the whole genus, which are distributed throughout Asia, Europe, America and other continents. There are 5 species of natural distribution in our country, all of which belong to the bare bud hickory group, namely Zhejiang hickory (Carya cathayensis), Hunan hickory (Carya hunanensis W.C.Cheng et R.H.Chang ex Chang et Lu), Guizhou hickory (Carya kwewhowe Kuang et A.M.Lu), Vietnamese hickory (Carya Tonkinensis H.Lec.) and Dabie Mountain hickory (Carya dabieshanesis M.C.Liu et Z.J.Li). Among all 18 species, there are only two kinds of pecans in the United States and Zhejiang pecans, which are the most widely used in artificial cultivation. [0003] Due to the significant eff...
