Application method of nitrogen-phosphorus-potassium chemical fertilizer in full bearing period of apple trees

Abstract

The invention belongs to the technical field of apple tree nutrition and fertilizer application, and in particular relates to an application method of a nitrogen-phosphorus-potassium chemical fertilizer in a full bearing period of apple trees. A full set of fertilizer application recommendation schemes such as the consumption, the proportion, the split application period and the split application method of the nitrogen-phosphorus-potassium chemical fertilizer can be obtained by only needing nutrient testing data, a target yield, tree growth situations and the like. By virtue of the method, multiple benefits such as the saving of the chemical fertilizer, the yield increasing, the high quality, the enrichment of soil fertility, the environmental friendliness and the like can be achieved.

Description

technical field [0001] The invention belongs to the technical field of apple tree nutrition and fertilizer application, and in particular relates to a method for applying nitrogen, phosphorus and potassium chemical fertilizers during the full fruit stage of apple trees. Background technique [0002] The fruit industry is an important traditional, efficient, and characteristic industry in our province. In recent years, the area has been stable at about 10 million mu, and the total output and output value have been in the forefront of the country for many years. Especially apples are widely planted in our province, and several advantageous production areas such as Yantai, Weihai, Linyi, and Yiyuan have been formed, and the output accounts for about 60% of the total fruit output. In advantageous production areas, apple income is the main source of income for farmers and plays a major role in increasing farmers' income and becoming rich. In the past 20 years, in order to obtain...
