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...

Problems solved by technology

Red Fuji apples require different mineral nutrients at different stages of growth and development. If fertilization cannot be carried out according to the nutritional characteristics of apples at each growth stage, it will not only fail to meet the normal life activities of apples, but also cause physiological disorders, and at the same time, it will cause fertilizer loss. waste of
