Nutritional fertilizer for apple and preparation method thereof

Abstract

The invention relates to a nutritional fertilizer for an apple. The nutritional fertilizer comprises an autumn topdressing formula, a pre-bloom topdressing formula and a fruit-expansion topdressing formula. According to the invention, topdressing fertilizers for different stages are respectively prepared; in an autumn topdressing fertilizer, a phosphorus potassium fertilizer is used as a main component, organic fertilizers and trace elements are supplemented, so a fruit tree can store considerable nutrients, which is favorable for later-stage growth and the fruit setting rate of a fruit tree; in a pre-bloom topdressing fertilizer, a nitrogen phosphorus fertilizer is used as a main component, considerable trace elements are supplemented, so growth of branches and leaves and differentiation of flower buds are promoted and the fruit setting rate is increased in virtue of rise of temperature in spring; and in a fruit-expansion topdressing fertilizer, a potash fertilizer is used as a main component to promote fruit expansion, ensure the color and maturation of fruit and improve output and quality, sweetness and taste of the fruit are both good, and income of planters is substantially increased.

Description

technical field [0001] The invention belongs to the technical field of apple planting, in particular to an apple nutritional fertilizer and a preparation method thereof. Background technique [0002] Apple is a deciduous tree with oval leaves, white flowers with blush, round fruit, sweet or slightly sour, is a common fruit, rich in sugar, starch, ascorbic acid, fat, protein, pectin, carotene, Nutrients such as nicotinic acid, calcium, magnesium, and zinc have the functions of diet therapy and auxiliary therapy. Apples are native to Europe, Central Asia, West Asia and Turkey, and were introduced to China in the nineteenth century. Apple has strong adaptability, good yield, and long fruiting cycle. It is cultivated in Northeast China, North China, East China, Northwest China, Sichuan, and Yunnan. [0003] In the process of apple planting, in addition to organic base fertilizer, multi-stage topdressing should be carried out, which is generally divided into autumn topdressing,...

AI Technical Summary

Problems solved by technology

However, in actual planting, there is a common phenomenon of blind fertilization, that is, random application of fertilizers in the three top-dressing stages, which not only makes it difficult to improve fruit yield and quality, but also causes waste of fertilizers, which affects the further development of the fruit industry.
