Problems solved by technology

At present, in the apple production areas, most of the fruit farmers do not have a strong awareness of scientific fertilization. Fertilization is based on experience. Fertilizers can be applied with whatever fertilizer is available on the market. Whichever fertilizer is well advertised and the price is low, they can buy whichever fertilizer. Apple trees are not considered at all. What kind of fertilizer is needed; moreover, the fertilization technology is relatively extensive, and excessive nitrogen, phosphorus, and potassium fertilizers are serious, which not only results in high production costs and low fertilizer utilization rates, but also leads to decline in fruit quality, serious physiological diseases, and environmental pollution
[0005] At present, there are many fertilizer brands in my country's fertilizer market, with tens of thousands of formulas. However, there is no special fertilizer that really meets the needs of apple growth and development. Therefore, fruit farmers can only choose fertilizers based on experience. The needs of apple growth and development

Embodiment 1

[0013] The percentage by weight of the effective elements in the special formula fertilizer for apples in the present embodiment is as follows: nitrogen 19, phosphorus pentoxide 9, potassium oxide 17. The effective substances in the fertilizer are provided by the following substances: nitrogen-urea, phosphorus pentoxide-diammonium phosphate, potassium oxide-potassium sulfate. During the production and preparation process of this formula, 336 kg of urea, 196 kg of diammonium phosphate, 315 kg of potassium sulfate are required to produce 1000 kg of special formula fertilizer for apples, and the balance is excipients.

[0014] The special fertilizer for apples of the present invention is applied to a red Fuji apple orchard in Laishan District, Yantai City, Shandong Province, China, and 300 kg of the special formula fertilizer for apples prepared by the present invention is applied per hectare. The average apple yield in the district increased by 4800 kg / hm 2 , the high-quality f...

Embodiment 2

[0016] The difference from Example 1 is that the effective elements in the special formula fertilizer for apples in this example have the following percentages by weight in terms of pure nutrients: 16 nitrogen, 11 phosphorus pentoxide, and 18 potassium oxide. The production of 1000 kg apple special formula fertilizer requires 254 kg of urea, 239 kg of diammonium phosphate, 333 kg of potassium sulfate, and the balance is excipients. Applying it to Yihong Fuji Apple Orchard in Qixia City, Yantai City, Shandong Province, China can also ensure an increase in apple production, increase the rate of high-quality fruit, and save costs.

Embodiment 3

[0018] The difference from Examples 1 and 2 is that the effective elements in the apple special formula fertilizer in the present embodiment are in the weight percentage of pure nutrients: nitrogen 17, phosphorus pentoxide 10, potassium oxide 18; produce 1 ton of apple special formula Fertilizer needs urea: 285 kg; diammonium phosphate: 217 kg; potassium sulfate: 333 kg, and the balance is excipients. Applied to multiple red Fuji apple orchards in Yantai, Qixia, Laishan, and Zhongzhuang Town, Yiyuan County, Zibo City, Shandong Province, China. After applying this formula, the apple yield, high-quality fruit rate, etc. are all higher than the formulas in Examples 1 and 2 , which is significantly better than traditional fertilization of apple orchards by fruit growers. Therefore, we conclude that the optimum weight percentages of effective elements in the apple special formula fertilizer in terms of pure nutrients are: nitrogen 17, phosphorus pentoxide 10, potassium oxide 18.

Abstract

The invention relates to a formulated fertilizer special for apple, wherein in the fertilizer, the weight percentages of the effective elements based on pure nutrient are as follows: 16-19% of nitrogen (N), 9-12% of phosphorus pentoxide (P2O5), 16-20% of potassium oxide (K2O) and reminder of excipient; the sum of the weight percentages of the total nutrients (N+P2O5+K2O) is 45. The invention provides a formulated fertilizer special for apple based on test results for many years according to absorption rule of growth and development of the apple tree for nitrogen, phosphorus and potassium. Compared with accessible fertilizers on the market, the formulated fertilizer special for apple has rational content proportion of the nutrient, fits absorption rule of the apple for the nutrients, notably satisfies requirement of each important development period of the apple for the nutrients, notably improves weight of single apple fruit and high-quality fruit rate, improves fruit quality and improves utilization rate of the fertilizer.

Description

[0001] (1) Technical field [0002] The invention relates to a special formula fertilizer for apples, which belongs to the technical field of fertilizers. (2) Background technology [0003] my country is the world's largest producer of apples. In 2009, the country's apple planting area was about 2.127 million hectares, with a total output of more than 31.93 million tons, accounting for 1 / 3 and 1 / 4 of the world's total. More than 40% of the total output value. There are 48 million farmers in our country who are directly or indirectly engaged in apple production. The apple industry has become one of the pillar industries in the countryside, and has played an important role in developing the rural economy, accelerating the adjustment of the rural industrial structure, and helping farmers get rid of poverty and become prosperous. [0004] In order to ensure high and stable apple yields, apple orchards need to invest a lot of chemical fertilizers every year. At present, ...
