Embodiment
[0051] In Ji County, a total of 200 mu of fields with similar soil quality, water content and environment were selected, of which 100 mu were applied topdressing according to the tradition of the growers, and were named group A. The other 100 mu were topdressed according to the three-stage formula and named as Group B.
[0052] Groups A and B selected the same variety of apples for planting, and adopted the same amount of fertilizer. After two years of cultivation, the average fruit setting rate of group B increased by 15%, and the yield increased by 20%.
[0053] In the present invention, topdressing fertilizers of different stages are respectively prepared, and phosphorus and potassium fertilizers are mainly used in autumn topdressing, and organic fertilizers and trace elements are supplemented, so that fruit trees store a large amount of nutrients, which is beneficial to the growth and fruit setting rate of fruit trees in the later stage, and topdressing before flowering Ni...

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,...
