Embodiment 1

[0044] GA at different application rates 3 Effects on the growth, yield and quality of feijoa

[0045] In the case of applying fixed concentrations of 6-BA and SA at 100 and 400 mg / kg respectively in each treatment, different concentrations of GA were applied 3 (0, 10, 100, 200mg / kg), through 5 times on June 15, 2013, November 15, 2014, March 15, June 15 and November 15, four times were applied to Feijoa. different concentrations of GA 3 In March, May, and November 2014, the number of 36 feijoa branch increments, the number of flowers, and the number of fruits were counted. At the end of November 2014, a total of 216 feijoa fruits were collected from each plant to determine the average single fruit. Table 1 was obtained after calculating the average fruit setting rate and yield per plant.

[0063] Effects of different application rates of 6-BA on the growth, yield and quality of feijoa

[0064] A fixed concentration of GA was applied in each treatment 3 , SA each 100, 400mg / kg, apply different concentrations of 6-BA (0, 10, 100, 200mg / kg), and different dosages of GA 3 For the same test time, four different concentrations of 6-BA were applied to feijoa five times. 3 Test the same test method, count the number of shoots, flowering numbers, and fruiting numbers of a total of 36 feijoa plants, the single fruit weight of 216 fruits, calculate the fruit set rate, and yield per plant to obtain Table 3.

Abstract

The invention discloses a plant growth regulator capable of promoting growth and development of a feijoa first fruiting tree and an application method thereof. The plant growth regulator is characterized by being any one or mixture of more than two of gibberellin, cytokinin and salicylic acid. The application method of the plant growth regulator comprises the following steps: preparing the plant growth regulator into plant growth regulator aqueous solution, dividing the plant growth regulator aqueous solution equally and carrying out foliar application of the plant growth regulator aqueous solution on the feijoa first fruiting tree in a growing period of 4-6 years for 1-3 times on sunny days of March, June and November respectively, wherein spraying application amount every time meets the condition that all the blades of the feijoa first fruiting tree are covered by the plant growth regulator aqueous solution. By adopting the plant growth regulator disclosed by the invention, the feijoa first fruiting tree can rapidly and fully acquire required nutritional ingredients in each growing period, balanced and sufficient nutrition is kept, normal development of flowers and fruits can be promoted while vegetative growth of a feijoa tree is promoted, and single-fruit weight, single plant yield and quality are improved.

Description

technical field [0001] The invention belongs to the planting of fruit trees, and relates to a plant growth regulator for promoting the growth and development of feijoa primary fruiting trees and an application method thereof. It is especially suitable for the application and cultivation of the plant growth regulator of the feijoa primary bearing trees whose growth period (or called tree age) is between 4 and 6 years. Background technique [0002] Feijoa (Feijoa sellowiana Berg.) is a plant of the genus Myrtaceae, which originated in Brazil, Argentina, Chile and other countries in South America. It is a perennial subtropical evergreen shrub plant. The mixed aromatic smell of guava or pineapple and strawberry, long-lasting fragrance, also known as pineapple guava. The shrub-like crown of feijoa, green fruit and red flowers make it also have a strong decorative effect, and can be used as landscaping tree species for ornamental tree species; feijoa fresh fruit is high in vitami...
