Fertilizing method for reducing apple rot morbidity and improving apple quality

Abstract

The invention provides a fertilizing method for reducing apple rot morbidity and improving apple quality, wherein the fertilizing method includes steps of S1, applying alga organic fertilizer, soil seasoning agent and dual-alga fertilizer after picking a fruit; S2, applying dual-alga benefiting and soil regulating organic fertilizer and full microbial agent in sprouting period; S3, applying calcium magnesium fertilizer (15-0-0-15-7), dual-algae benefiting and soil regulating organic fertilizer and blade surface zinc fertilizer in young fruit period; S4, applying calcium magnesium fertilizer (15-0-0-15-7) and massive element water-soluble fertilizer in fruit expanding period; S5, applying dual-algae humic acid contained water-soluble fertilizer and blade surface calcium fertilizer in fruit turning stage. The fertilizing method has the beneficial effect that the fertilizing method is an accurate fertilizing method; the root fertilization is matched with the blade surface fertilization; during the fertilizing period, the apple nutrition demand is satisfied, the fertilizer utilization rate is improved.

Description

technical field [0001] The invention relates to a fertilization method for reducing the incidence of apple rot disease and improving apple quality, and belongs to the technical field of apple disease prevention planting. Background technique [0002] Apple is one of the fruit tree varieties with the widest cultivation area and the largest yield in my country. It is a relatively cold-resistant tree species and is mainly distributed in the vast areas north of the Yangtze River in China. The most suitable cultivation temperature is an annual average of 9-14°C, and the average temperature of the coldest month is between -10-10°C. During the growth period from April to October, the average temperature is required to be within the range of 10-20°C, and the average temperature is 6-10°C. Can be cultivated between 17°C. [0003] Apple trees are perennial woody plants with deep roots and long life spans. During the entire growth and development process, in addition to the growth cy...

Problems solved by technology

However, judging from the planting status in each production area, most fruit growers are too lazy to apply organic fertilizers, and simply rely on the topdressing of fruit trees before germination

[0006] 2. Single fertilization

[0007] 3. The amount of nitrogen and phosphorus fertilizers used in intensive orchards is generally high, and the medium and trace elements calcium, magnesium and boron are deficient

[0008] 4. Soil acidification in orchards is widespread, and iron, zinc and boron are deficient

The patent document with the publication number CN102763515 A provides a fertilization method for promoting the production and quality improvement of perennial apples. The defect of the method is that all the topdressing fertilizers are foliar topdressing and cannot meet the demand of apples for fertilizers. The root system provides water and nutrition for the tree body. Main organs, and foliar topdressing is greatly affected by climate and temperature, too dry climate conditions can easily cause leaf fertilizer damage and aggravate the occurrence of diseases; foliar topdressing can't meet the demand for fertilizers during the peak growth of apple roots in spring

The patent with the publication number CN102282949 A invented a method of fertilizing bagged apples. The fertilization period is unreasonable, especially ignoring the urgent demand for nutrients after apple picking. At this time, the lack of fertilizer will seriously affect the growth of roots and the differentiation of flower buds in the coming year. Tree vigor, resulting in high incidence of disease
