A special fertilizer for big cherry and its preparation method and application

Abstract

The invention discloses a special fertilizer for large cherries, which comprises the following components in parts by weight: 30-80 parts of urea, 2-10 parts of potassium dihydrogen phosphate, 30-80 parts of potassium sulfate, 1-5 parts of borax, sulfuric acid 2-8 parts of ferrous iron, 1-5 parts of pure zinc fertilizer, 2-8 parts of ammonium molybdate, 2-10 parts of calcium carbonate, 2-5 parts of resin coating agent. The special fertilizer for cherries of the present invention is added through the resin coating agent so that the fertilizer can obtain the slow-release function, so that various elements of the fertilizer are slowly released in stages to supply nutrient elements for the growth of cherries. The present invention also provides a preparation method for the above-mentioned fertilizer , the method is simple and feasible, and is suitable for large-scale implementation. The application method of the present invention is to spray fertilizers on different parts at suitable periods according to the cycle development process of large cherry, so that the fruit setting rate of Longguan and Longbao is 48.2% and the single fruit weight is 23.3 %.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a special fertilizer for big cherry and its preparation method and application. Background technique [0002] Big cherry, also known as Western cherry, was introduced to Yantai, Shandong Province by Western missionaries and expatriates in the 1870s. It is a general term for European sweet cherry, European sour cherry and their hybrids, because the fruit is larger than the original Chinese cherry. name.

It can also regulate the spleen, regulate qi and blood, calm the liver and remove heat. It is a health-care fruit that prolongs life. Experts call it "vitamin pills". Big cherry fruit is big and delicious, with an average single fruit weight of 12-14 grams, and the largest single fruit weight...

Problems solved by technology

[0003] At present, the fertilizers for large cherries generally do not have slow-release function. In addition, the nutrients in the fertilizers are not comprehensive, which leads to the ineffective absorption and utilization of fertilizers during the growth process of cherries, resulting in malnutrition in the later stage. In addition, it is also necessary to adjust the timing of fertilization during the fertilization process. , leading to nutrient imbalance and low utilization rate of fertilizer absorption, leading to low yield of large cherries
