TABLE 1 average number of flowers and average yield of passion fruit branches by different methods of planting
From the table 1, the method can greatly improve the flowering number and the fruiting number of the passion fruits in the early stage and increase the acre yield and the income. The lateral buds planted in clusters germinate from 12 months to 1 month, 15-20 leaves grow in the beginning of 4 months, and 1 flower can grow in each leaf axilla after the branches are aged. The plants in the conventional planting process are in a growth stopping state when in overwintering, the plants are recovered to grow in 3 months, lateral buds are germinated only at the beginning of 4 months after topping, and the leaves of the branches are not mature enough in 4 months, so that flowers are difficult to form. The invention has the advantages of more flowers, more fruit bearing and high mu yield.
TABLE 2 fruit quality of passion fruit planted by different planting methods
As is clear from Table 2, the method of the present invention greatly increases the number of fruits in the early stage, so that both the weight of single fruit and the quality of fruit are improved, and the price of fruit is high. Compared with conventional planting, the method has the advantages that the overwintering cost of the passion fruits is increased by about 400 yuan/mu, but the yield of the example 1 is increased by 15593 yuan/mu, and the yield of the example 2 is increased by 15289 yuan, so that the method greatly improves the benefits of passion fruit planting.
The foregoing description is directed to the preferred embodiments of the present invention, but the embodiments are not intended to limit the scope of the invention, and all equivalent changes or modifications made under the technical spirit of the present invention should be construed to fall within the scope of the present invention.
