Further preferably, the concentration of pipecolic acid is 20 to 80ppm, more preferably 40 to 60 ppm.
On the basis of the basic formula of the compound foliar fertilizer, the intrinsic quality of fruits and vegetables can be obviously improved by adding pipecolic acid or malic acid, for example, the content of soluble solid and vitamin C is improved, and the yield is improved, so that the compound foliar fertilizer can be used for producing fruits and vegetables.

4. Compound foliar fertilizer (C) containing pipecolic acid
20ppm of pipecolic acid, 1000ppm of algal polysaccharide, 10ppm of 2, 3-butanediol, 10ppm of 3-hydroxy-2-butanone, 1000ppm of monopotassium phosphate, 500ppm of ferrous sulfate and 0.01 percent of Tween 20 by mass, and the solvent is water.
5. Composite foliar fertilizer containing jasmonic acid (D)
20ppm of jasmonic acid, 1000ppm of algal polysaccharide, 10ppm of 2, 3-butanediol, 10ppm of 3-hydroxy-2-butanone, 1000ppm of monopotassium phosphate, 500ppm of ferrous sulfate and 0.01 percent of tween 20 by mass, and the solvent is water.
Dissolving micromolecular alcohol ketone (2, 3-butanediol and 3-hydroxy-2-butanone) by using water to prepare a mother solution with 10000ppm for standby, preparing a tween aqueous solution with the mass fraction of 0.01%, respectively adding algal polysaccharide, monopotassium phosphate and ferrous sulfate with corresponding ratios, stirring for 30 minutes at room temperature, finally adding micromolecular alcohol ketone and organic acid with corresponding ratios, and stirring for 30 minutes at room temperature.
II, fertilizing scheme:
1. waxberry:
the variety is Myrica rubra Dongkui, which is planted in Majian town of Lanxi, Zhejiang province, and the fruit tree bearing fruits in 3 years
Spraying the waxberry seeds for 1 time respectively before the hard core period (10-15 days after the flowering) and after the hard core period (40-45 days after the flowering), wherein the spraying mode is to mix uniformly and spray, the spraying amount is 3 liters per tree, harvesting is carried out when the sugar degree of the waxberry reaches more than 10, 4 cells are arranged (repeated), and 3kg is harvested for quality detection in each cell.
2. Pakchoi:
variety: weisheng hybrid black leaf cabbage planted in Tantang township of white cloud region of Guangzhou city, Guangdong province
Spraying the pakchoi for 1 time respectively in the seedling stage (3-4 leaves) and the growth stage (7-8 leaves), uniformly spraying, spraying the pakchoi for 600 liters per hectare, harvesting 40 days after field planting, setting 4 cells (repeating), and harvesting 3kg per cell for quality detection.
The blank control group does not apply foliar fertilizer, and other field management is not different.
Then, the waxberry and the pakchoi are detected, and the adopted fruit or vegetable quality detection indexes and methods are as follows: soluble solids (reference: GB T12295-.
The waxberry quality detection results are shown in table 1:
TABLE 1
Composite foliage fertilizer Soluble solids (%) Ascorbic acid (Vc) mg/100g
A 11.6±0.21b 8.8±0.69b
B 11.5±0.29b 8.4±0.78b
C 12.5±0.31a 10.4±0.88a
D 11.7±0.23b 8.7±0.77b
Basic formula of compound foliar fertilizer 11.5±0.17b 8.4±0.85b
Blank control 10.7±0.24c 6.5±0.68c
Note: the different lower case letters in the table indicate that the difference between the treatments of the same index is significant (p <0.05), as follows.
From table 1, it is seen that pipecolic acid can significantly increase the soluble solid solution and ascorbic acid content of waxberry compared to the blank control, the basic formulation of the compound foliar fertilizer and other organic acids (salicylic acid, malic acid and jasmonic acid).
The results of the yield and quality test of pakchoi are shown in table 2:
TABLE 2
Figure BDA0003264019620000041
Figure BDA0003264019620000051
From table 2, it is seen that pipecolic acid can significantly increase the yield and ascorbic acid content of pakchoi compared to the blank control, the basic formulation of the compound foliar fertilizer, and other organic acids (salicylic acid, malic acid, and jasmonic acid).
3. The effect of different concentrations of pipecolic acid on the quality and yield of sugar oranges.
Adding pipecolic acid into a basic formula of the compound foliar fertilizer, wherein the concentrations are respectively set as follows: 20ppm, 40ppm, 60ppm, 80ppm, 160ppm, 320 ppm. The basic formula of the compound foliar fertilizer is used as a contrast, the basic formula of the compound foliar fertilizer is not applied as a blank contrast, the compound foliar fertilizer is sprayed for 1 time in the swelling period and the color-changing period of the sugar orange respectively, 3 liters of water is sprayed to each tree (fruit tree bearing fruits in 3 years), the harvest is carried out when the sugar degree of the sugar orange reaches more than 10, 4 cells (repetition) are set, and 4 fruit trees with the same size are planted in each cell.
After harvesting, the yield of each plant is counted, and 3kg of the plant is harvested from each cell for quality detection. The detection method is the same as that of waxberry, and the results are shown in Table 3:
TABLE 3
Figure BDA0003264019620000052
Figure BDA0003264019620000061
As can be seen from Table 3, 20-80ppm of pipecolic acid can significantly improve the yield of each plant of sugar orange, 40-60ppm of pipecolic acid can significantly improve the soluble solid content of sugar orange, and 40-80ppm of pipecolic acid can significantly improve the vitamin C content of sugar orange.
