(4) color conversion: the flowering phase of the pomelo tree enters a fruit expanding period in 2-3 months and 5-6 months, and the pomelo fruits are bagged; spraying nutrient solution on the surfaces of the pomelos and the passion fruit at intervals of 15-20 days at the bottom of 7-8 months, and realizing color change of the pomelos in the period; the nutrient solution is 1700 times of a composition of citric acid chelated titanium, urea and potassium dihydrogen phosphate in a mass ratio of 1:25: 18;
(5) harvesting: and (4) harvesting the grapefruit when the grapefruit turns to red-yellow, continuously performing daily management on the passion fruit after harvesting, placing a drosophila yellow plate for insect prevention, and entering a continuous harvesting period in 9-12 months.
Control group: in contrast to example 6, no passion fruit was interplanted. FIG. 2 is a photograph comparing the fruit harvesting time period of the method of example 6 with that of the control group (the left is the control group, and the right is the present application). As can be seen in fig. 2. The grapefruit planted in example 6 is orange red, which indicates that the color conversion effect is good.
Comparative example 1: the difference from example 6 is that the nutrient solution was replaced by water.
Comparative example 2: compared with the comparative example 1, the base fertilizer does not contain peanut bran and EM bacterial liquid.
The grapefruit and passion fruit planted in the examples 1-6, the control group and the comparative examples 1-2 are tested and compared with data, and are shown in the table 1.
TABLE 1
Figure BDA0002999083150000071
As can be seen from table 1, the color conversion rate, the yield and other data of the examples 1 to 6 of the invention are all due to the comparative example and the control group, and by interplanting passion fruit, the color conversion rate of the grapefruit is improved by 55% compared with the control group, so that the grapefruit has better quality and higher commodity value, and meanwhile, the grapefruit has the additional economic benefit of the byproduct passion fruit, the cost of setting up a shaddock by the traditional method is saved, multiple purposes are achieved, and the product yield is greatly improved. The color conversion rate of the example 6 is improved by 20% compared with that of the comparative example 1, which shows that the color conversion rate of the grapefruit can be further improved and the natural color conversion of the grapefruit can be promoted by matching the nutrient solution provided by the invention.
Although the present invention has been described with reference to the specific embodiments, it should be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
