Abstract

The invention discloses a special formula fertilizer for lemon young trees and a preparation method thereof. The special formula fertilizer for lemon young trees is composed of urea, monoammonium phosphate, potassium sulfate, calcium magnesia phosphate fertilizer, humic acid, borax, white vitriol, magnesium oxide and diatomite. The preparation method comprises the following steps: respectively pulverizing urea, monoammonium phosphate, calcium magnesia phosphate fertilizer and potassium sulfate, carrying out aggregation granulation by humidification and heating, meanwhile, adding a mixture of the magnesium oxide, borax, white vitriol, humic acid and diatomite, drying the granulated material, screening and cooling to obtain the special fertilizer for lemon young trees. The method has the advantages of wide raw material sources and high universality, and is easy to implement and simple to operate. The special fertilizer disclosed by the invention implements reasonable balanced nutritional requirements for the young lemon garden, accelerates the growth and development of the lemon young trees, and can enable the lemon young trees to form crowns and blossom in advance, thereby putting into production.

Description

technical field [0001] The invention belongs to the technical field of fertilizer preparation and utilization, and in particular relates to a special formula fertilizer suitable for young lemon trees and a preparation method thereof. Background technique [0002] Lemon is an important species of citrus in the Rutaceae citrus genus. The lemon industry is one of the characteristic industries in my country's modern citrus industry technology system. Its planting is mainly distributed in Anyue, Yunnan Dehong, Baoshan, Pu'er, Lincang, etc. In the region, lemons have become a dominant and characteristic economic industry in agriculture in the mountainous areas of Southwest my country. In the subtropical and tropical regions of southern my country, the soil type of lemon planting is mainly acidic red soil. For many years, the soil in this area has mainly been planted with sugarcane, tropical perennial crops and crops with high multiple cropping index. Chemical fertilizers and simple...
