Problems solved by technology

At present, most of the medium and trace elements applied on peach trees are applied in the soil, but the composition of the medium and trace elements applied to the soil is easily fixed by the soil, and the area of ​​the peach tree root system is limited by the fertilizer. The efficiency is generally not high and cannot meet their nutritional needs; some also use external fertilization (such as foliar spraying) to supplement medium and trace elements, but the effect is not obvious enough. The reason is that the formula ingredients are difficult to adapt to the nutrition of peach trees. need
Thereby existing peach tree fertilization mode and method seem powerless for solving the above problems

Embodiment 1

[0029] Example 1 Fertilization test of Pinggu big peach growth period

[0030] (1) Test design and treatment Test location: Xujiawu Village, Pinggu District, test variety: Beijing No. 24, basic soil properties: soil is light soil, organic matter: 0.87%, available silicon: 90.11 mg / kg, pH: 6.08, nitric acid State nitrogen: 12.69 mg / kg, available phosphorus: 71.67mg / kg, available potassium: 90 mg / kg.

[0031] Two treatments were set up in the experiment, each with 10 fruit trees:

[0032] ① Routine control

[0033] Fertilize according to local farmers' habits: apply compound fertilizer (15-15-15) 2-2.5 kg / tree respectively during peach expansion period and hard core period, and do not apply foliar spray fertilizer;

[0034] ②Optimize fertilization method (habitual fertilization + fertilization method of the present invention)

[0035] Fertilization method of the present invention:

[0036] 1) Flower fertilizer On April 29, 2010, there were a few flowers, and B and Zn micro-f...

Embodiment 2

[0074] Embodiment 2 A kind of peach tree foliage spray fertilizer, containing K 2 SO 4 0.08%, MgSO 4 ?7H 2 O 0.08%, MnSO 4 ?H 2 O 0.05%, ZnSO 4 ?7H 2 O 0.1%, Ca(NO 3 ) 2 ?4H 2 O 0.3%, H 3 BO 3 0.08%, NaEDTA-Fe 0.08%, HA 0.03%, Na 2 SiO 3 ?9H 2 O 0.1%, the rest is water.

[0075] Above-mentioned foliage spray fertilizer is applied to the fertilization method of peach tree growth period, comprises the following steps:

[0076] (1) Flower fertilizer Spray foliar fertilizer in the early flowering period, which contains 0.2% boric acid, 0.15% zinc sulfate, and 0.05% humic acid solution, and the spraying amount is 30 L / 667m 2 ;

[0077] (2) Fruit Preserving Fertilizer 20 days after flowering (fruit setting period), spray the above-mentioned large peach leaf surface spray fertilizer, and the spray amount is 30 L / 667m 2 ;

[0078] (3) Swelling fertilizer 50 days after flowering (pre-swelling stage), spray the above-mentioned big peach foliar spray fertilizer, and t...

Embodiment 3

[0081] Embodiment 3 A kind of peach tree foliage spray fertilizer, containing K 2 SO 4 0.4%, MgSO 4 ?7H 2 O 0.4%, MnSO 4 ?H 2 O 0.25%, ZnSO 4 ?7H 2 O 0.2%, Ca(NO 3 ) 2 ?4H 2 O 0.5%, H 3 BO 3 0.3%, NaEDTA-Fe 0.3%, HA 0.1%, Na 2 SiO 3 ?9H 2 O 0.28%, the rest is water.

[0082] The above-mentioned foliage spraying fertilizer is applied to the fertilization method of peach tree growth period and is basically the same as embodiment 1.

Abstract

The invention relates to a peach tree foliage spraying fertilizer and a growth period fertilization method for a peach tree, aiming to solve the problem of poor peach fruit quality in the existing fertilization mode. The foliage spraying fertilizer contains ingredients, such as K2SO4, MgSO4.7H2O, MnSO4.H2O, ZnSO4.7H2O, Ca(NO3)2.4H2O, H3BO3, Na ethylene diamine tetraacetic acid (EDTA)-Fe, HA, Na2SiO3.9H2O and the like. The main fertilization mode is characterized in that a proper quantity of foliage spraying fertilizer is applied respectively in the early florescence, the fruit setting fruit, the early swelling period, the later swelling period and the mature period. The peach tree foliage spraying fertilizer has the active beneficial effect that fruit has the characteristics of high weight increment speed, good color, consistent maturity and high commodity fruit rate after the fertilizer is applied. In addition, the peach tree foliage spraying fertilizer has a quick fertilizer effect and can satisfy requirements of peach trees on nutrients. By utilizing the fertilization method, not only can the normal production of peach trees be maintained, but also excessive vegetative growth can be inhibited, and the soil pollution risk is lowered. The fertilization method also has the advantages of low fertilization cost and obvious economic benefit.

Description

technical field [0001] The invention relates to the field of fruit tree cultivation and fertilization, in particular to a method for spraying fertilizer on the leaves of peach trees and fertilizing methods during the growth period of peach trees. Background technique [0002] With the adjustment of the agricultural structure and the improvement of people's living standards, people's demand for fresh fruits has increased. If you are careful, you may have discovered that most of the fruits now can no longer taste the same as before. For example, the big and red strawberries are not sweet at all; the thorny cucumbers with top flowers are hard to taste after a few bites; the ruddy peaches are tasteless... The quality of the fruits has declined, and people are complaining . It is undeniable that improper fertilization is one of the important reasons for the decline of fruit quality. For example, some fruit growers want to increase the yield of fruit, so they apply excessively hi...
