Embodiment 1

[0042] On April 28, 2017, it was tested in Hanli Village, Leigao Town, Leizhou City, Guangdong Province. The foliar fertilizer formula of the present invention was 0.75% amino acid calcium; 1.0% potassium fulvic acid; 0.25% Tween 20 and the balance The water should be sprayed 3 times at intervals of 7 days, and the spraying will be stopped until May 12. A total of 200 plants were processed. 200 pineapple seedlings not applied with the foliar fertilizer in the same test area during the same period were used as control samples.

[0043] On May 31, 2017, the fruit was harvested, and the statistics of pineapple cracking were as follows: the cracking rate of pineapple fruit without spraying foliar fertilizer was 65%, while the cracking rate of pineapple fruit sprayed with the foliar fertilizer of this embodiment was 15%. figure 1 Shown are the pictures of pineapple fruit not sprayed with foliar fertilizer and sprayed with the foliar fertilizer of this embodiment.

Embodiment 2

[0045] On April 20, 2018, it was tested in Huxiu New Village, Zhanjiang City, Guangdong Province. The foliar fertilizer formula of the present invention was 1.5% amino acid calcium; 0.5% potassium fulvic acid; 0.5% Tween 20 and the remaining water. Once every 7 days, spray 3 times, and stop spraying on May 4. A total of 200 plants were processed. 200 pineapple seedlings not applied with the foliar fertilizer in the same test area during the same period were used as control samples.

[0046]On May 23, 2018, the fruit was harvested, and the statistics of pineapple cracking were as follows: the fruit cracking rate of the unsprayed foliar fertilizer was 75%, while the cracking rate of the sprayed foliar fertilizer of the present invention was 8.5%.

Embodiment 3

[0048] On April 18, 2019, in Huxiu New Village, Huguang Town, Zhanjiang City, Guangdong Province, the formula of the foliar fertilizer of the present invention was 1.1% amino acid calcium, 0.75% potassium fulvic acid, 0.4% Tween 20 and the rest Water, 1 time at intervals of 7 days, sprayed 3 times, and stopped spraying on May 02. A total of 200 plants were processed. 200 pineapple seedlings not applied with the foliar fertilizer in the same test area during the same period were used as control samples.

[0049] On May 21, 2019, the fruit was harvested, and the statistics of pineapple cracking were as follows: the fruit cracking rate of the unsprayed foliar fertilizer was 54%, while the cracking rate of the sprayed foliar fertilizer of the present invention was 12.5%.

[0050] It can be seen from the above examples that the foliar fertilizer provided by the invention has a remarkable effect in preventing fruit cracking, and greatly reduces the rate of pineapple fruit cracking....

Abstract

The invention provides a foliar fertilizer and application thereof, and a method for preventing and treating pineapple fruit cracking. The foliar fertilizer is prepared from the following components in percentage by weight: 0.75%-1.5% of amino acid salt, 0.5%-1.0% of humate, 0.25%-0.5% of polyoxyethylene ether sorbitan ester and the balance of water. According to the foliar fertilizer, the pressure resistance and extensibility of cells are enhanced, the anti-cracking capacity of fruit peels is enhanced, calcium absorption is promoted, the fruit quality is improved, the amount and time of the foliar fertilizer attached to the surfaces of leaves are increased, the foliar fertilizer is promoted to penetrate through a leaf biological membrane and be absorbed on the surfaces of the leaves, and the pesticide effect is enhanced. The method has an obvious effect of preventing and treating pineapple fruit cracking, and the fruit quality is obviously improved after the method is used.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a foliar fertilizer and its application, and a method for preventing and controlling pineapple fruit cracking. Background technique [0002] Cracking fruit is a kind of physiological disease widely existing on fruit trees. It all occurs on fruit trees such as grapes, apples, lychees, oranges, sweet cherries, plums, etc., which seriously affects the quality and appearance of fruits. Cracking fruit has almost no commercial value. Bring huge losses to production. Pineapple is one of the famous and high-quality fruits in tropical and subtropical regions of my country. It is widely cultivated in Guangdong, Hainan, Guangxi and Yunnan. 80% of the cultivated varieties in the main pineapple producing areas in my country are "Bali". In recent years, due to the over-concentration of the production period, blind use of bulking agents and black hearts caused by low temperat...
