[0024] Example 1 Correlation analysis between mineral elements and fruit quality (SSC, firmness and weight)

[0025] (1) Test materials and methods The test was carried out in 2009 with Zhongyoutao No. 4 in Dangshan County, Anhui Province as the research material. The leaves were taken 60 days after flowering, and the leaves of 3 Zhongyoutao No. 4 plants were taken from each orchard, a total of 20 orchards. Around 65 days after flowering, the more consistent fruits were taken, and the SSC, hardness and weight of the fruits were measured.

[0026] (2) Determination of fruit quality indicators

[0027] Soluble solids: use PAL-1 (ATAGO, Japan) handheld digital display instrument, select 1 point opposite to the suture line and 2 symmetrical points on both sides for each fruit, measure 10 fruits, and calculate the average value;

[0028] Fruit weight: measure the weight of 10 fruits with a digital display electronic balance, and calculate the average value;

[0029] Hardness: Use...

[0033]Example 2 Determination of the scope of a single mineral element

[0034] (5) Research materials and experimental design According to the correlation between leaf mineral element content and fruit quality, we determined that five mineral elements, N, K, Fe, Ca and Zn, had a greater impact on fruit quality. A control experiment was adopted, and the foliage of Zhongnectao No. 4 was sprayed four times at 10d, 20d, 30d and 40d before maturity. For details, please refer to the gradient setting of spraying. single mineral element. N, K, Fe, Ca, Zn these mineral elements set the gradient as N1 (7.5mM), N2 (5mM), N3 (2.5mM), water control; K1 (1.875mM), K2 (1.25mM), K3 (0.625mM), water control; Fe1 (0.015mM), Fe2 (0.01mM), Fe3 (0.005mM), water control; Ca1 (3mM), Ca2 (2mM), Ca3 (1mM), water control; Zn1 ( 0.015mM), Zn2 (0.01mM), Zn3 (0.005mM), water control. Note: The excipient EDTA is added to the ferrous ion 2 Na. Take more consistent peach fruit to determine the fruit qu...

Abstract

The invention discloses a fertilizer for spraying leaves of peach trees, which comprises 3.5 mM N, 1.25 mM K, 0.01 mM Fe, 1.0 mM Ca, 0.01 mM Zn, 0.2 ml / L Triton X-10 and 0.1 mM EDTA2Na. The fertilizer for the leaves of the peach trees is easy to prepare and convenient to use, can remarkably improve the SSC, the weight and the hardness of fruits of the peach trees, is suitable for large-scale industrial production, and dose not pollute the environment.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a fertilizer for improving the quality of peach fruit. Background technique [0002] As the third largest deciduous fruit tree in my country, peach is of great significance to increase farmers' income and optimize industrial adjustment. However, due to reasons such as pruning, fruit thinning, improper water and fertilizer management, etc., the advantages of the variety cannot be fully utilized, which ultimately affects the overall quality of peach fruits. Among them, the level of mineral elements is one of the most important factors affecting fruit quality. Mineral elements not only affect the appearance, color and size of fruits, but also affect the internal quality of fruits, such as SSC, hardness, storage resistance and resistance. The mineral elements in the fruit are also important indicators for evaluating its nutritional value. Therefore, proper supplementation of mineral elements for fru...
