Anniversary application method of leaf fertilizer for red fuji apples

Abstract

The invention relates to an anniversary application method of leaf fertilizer for red fuji apples. The method comprises the following steps of: applying nitrogenous fertilizer, phosphatic fertilizer and potassic fertilizer according to the growth characteristic and the nutrient requirement of the red fuji apples at the seven key growth and development stages, i.e., before germination, after germination, at the blooming period, at the vigorous young sprout growth period, at the fruit expansion period, at the later period of fruit development and before defoliation; and meanwhile, replenishing trace elements such as calcium, ferrum, zinc, boron and the like in good time. The anniversary application method can be used for effectively increasing the fruit setting rate of applies, preventing and controlling the little leaf disease, the yellowtop, the fruit shrink disease and the bitter pits, improving the fruit quality and increasing the fruit yield. If the anniversary application method is used for apple production, the growth vigour of a tree body is remarkably enhanced, the occurrence rate of various physiologic diseases is remarkably reduced, the high-quality fruit rate is increased by 23%, and guarantee is provided for the increment of fruit growers and the sustainable development of fruit industry.

Description

(1) Technical field

[0001] The invention relates to an annual application method of red Fuji apple leaf fertilizer, which belongs to the technical field of fertilizers. (2) Background technology

[0002] 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.

[0003] In recent years, through a large number of investigations, we have found that fruit farmers often apply a large amount of nitro...

[0012] The applicant conducts experiments in Shezhuang Village, Zhongzhuang Town, Yiyuan, Shandong. The test material is 8-year-old red Fuji apple / Pingyi sweet tea, the distance between plants and rows is 3.0m×4.0m, and the test site is 4 mu. According to the scheme of this invention, the whole growth season in 207 carries out foliar fertilizer spraying to the tree body, establishes 2 processes:

[0013] One, utilize the red Fuji apple foliar fertilizer annual application method of the present invention:

[0014] 1) Spray a mixture of 2% urea and 1.5% zinc sulfate before germination; 2) Spray a mixture of 0.3% urea and 0.3% zinc sulfate after germination, and spray 3 times continuously; 3 ) Spray borax with a concentration of 0.3% during the flowering period; 4) Spray ferric citrate with a concentration of 0.2% for the long-term growth of new shoots, spraying twice continuously; 5) Spray borax with a concentration of 0.3% and 0.4 % calcium nitrate mixture, spray 3 times cont...

[0023] From 2007 to 2012, we carried out the experiment of the invention in the Red Fuji apple orchards in Laishan Town, Qixia City, and Feicheng City, Yantai, Shandong Province, involving a total of 640 mu of Red Fuji orchards, and achieved remarkable results, increasing the economic benefits of fruit farmers According to the statistics of the test results of 185 apple orchards in 5 years, after the application of the present invention, the yield per mu increases by 7.87%, the single fruit weight increases by 9.56g, the first-grade fruit rate increases by 23 percentage points, the sugar content increases by 1.5 units, and the growth of the tree body is obvious. Robust, the incidence of disease is reduced, and the economic benefit is increased by 453.81 yuan / mu.
