Problems solved by technology

However, the success rate of "caine" pineapple with ethephon is only 20-40%, and the plants do not bud, and return to the vegetative growth process, which seriously affects the yield formation and planting benefits of pineapple.
It is precisely because "caine" pineapples are difficult to flower out of season, so in my country's main pineapple producing areas such as Guangdong, Guangxi, and Hainan, fruit growers prefer to plant "queen species" with prickly leaves and inconvenient management, rather than planting leaf margins. The thornless and easy-to-manage "caine" variety is the main reason for the single structure of pineapple cultivars in my country

Embodiment 1

[0026] Time, October-December, 2016, location: Pineapple Garden of Wushan Fruit Tree Institute, Tianhe District, Guangzhou City, the variety of pineapple is Caine.

[0027] On October 12-13, the weather was fine, and at 4:00 p.m., 40% ethephon 415 times solution (415 times, that is, diluted to 415 times) was used to perfuse the heart once for 2 consecutive days, 100 mL each time.

[0028] One week later, on October 19, the heart was reperfused once with the same ethephon solution.

[0029] This is the original 2+1 mode of the present invention.

[0030] After 45 days, the pineapple plants began to bud, and the effect of promoting flowering reached 100%.

[0031] Different concentrations of ethephon were used to perfuse the heart 1-2 times for comparison, and the results are shown in Table 1.

Embodiment 2

[0036] Time, October-December, 2015, location: Pineapple Garden of Wushan Fruit Tree Research Institute, Tianhe District, Guangzhou City, the variety of pineapple is Caine.

[0037] On October 15-16, the weather was fine. At 4:00 p.m., the heart was perfused with 40% ethephon 410 times solution for 2 consecutive days, 100 mL each time.

[0038] One week later, on October 22, the heart was reperfused once with the same ethephon solution.

[0039] After 45 days, the pineapple plants began to bud, and the effect of promoting flowering reached 100%.

Embodiment 3

[0042] Time, October-December, 2014, location: Pineapple Garden of Wushan Fruit Tree Institute, Tianhe District, Guangzhou City, the variety of pineapple is Caine.

[0043] On October 13-14, the weather was fine. At 4:00 p.m., the heart was perfused with 40% ethephon 420 times solution for 2 consecutive days, 100 mL each time.

[0044] One week later, on October 21, the heart was reperfused once with the same ethephon solution.

[0045] After 45 days, the pineapple plants began to bud, and the effect of promoting flowering reached 100%.

[0046] The inventor began to test the technical method of the present invention in 2014, and continued for 3 years. The inventor used this technology in the pineapple garden of Wushan Fruit Tree Institute, Tianhe District, Guangzhou City to promote the flowering of caine-like pineapple out of season, and all achieved success.

Abstract

The invention discloses an effective anti-season flower formation method of cayenne pineapples. The method specially includes the following steps that in the autumn, on a certain day which is not rainy, 350-450 times diluted liquid of an ethephon aqueous solution is used for core irrigation of pineapple plants, and the current day is recorded as the first day; on the first day and the second day, core irrigation is continuously conducted once a day, from the seventh day to the tenth day, core irrigation is conducted once, and the use amount of the 350-450 times diluted liquid of the ethephon aqueous solution is 70-150 ml. A'2+1' mode is adopted for anti-season flower formation of the cayenne pineapples, the flower formation effect is good, and the success rate of flower formation reaches 100%. By means of the anti-season flower formation method of cayenne pineapples, the pineapple plants grow neat flower buds and flowers, and fruits grow well and are excellent in quality and condition.

Description

technical field [0001] The invention specifically relates to an effective anti-seasonal flowering method of caine-like pineapple. Background technique [0002] In pineapple production, due to differences in climate conditions, varieties, seedling types and sizes, and planting densities, the natural budding rate of pineapple is inconsistent, which affects the natural budding rate. The budding rate of pineapple varieties can be improved by artificial flower urging. [0003] The application of plant growth regulators in promoting flowering of pineapple began in the 1930s in my country, and Taiwan was the first place to use it. In 1938, calcium carbide was used to induce budding and flowering of pineapple. Guangdong, Guangxi, and Fujian have been used in production since the 1950s. At present, the flower urging agents used for artificial flower urging of pineapple include ethephon, calcium carbide, naphthalene acetic acid or sodium naphthalene acetate. Ethephon is used in the...
