Description

Jackfruit anti-cracking fruit leaf fertilizer, anti-cracking method and application

Technical Field

The invention relates to the technical field of fruit cracking prevention, in particular to a jack fruit cracking prevention foliar fertilizer, a fruit cracking prevention method and application.

Background

Jackfruit (also called pineapple), a evergreen arbor of the genera Artocarpus and Artocarpus in Moraceae, is a tropical fruit and generally weighs 2.5-20 kg, and most weighs more than 59 kg. The pulp can be eaten fresh or processed into canned food, preserved fruit and fruit juice. Jackfruit dehiscence is a physiological disease, generally the fruit dehiscence is generated when the fruit is close to mature, and is a common symptom, and at present, the common symptom is that: mainly due to the deficiency of trace elements, in particular calcium.

The jackfruit belongs to small fruits, the research foundation is weak, the jackfruit cracking is generally considered to be caused by the lack of calcium element at home at present, but no method for solving the problem of jackfruit cracking by measures such as calcium supplement and the like is provided.

Disclosure of Invention

The invention aims to provide a jack fruit anti-cracking fruit foliar fertilizer, an anti-cracking fruit method and application. The foliar fertilizer can effectively prevent jackfruit from cracking.

The invention provides application of a borax water solution as a jackfruit anti-cracking fruit leaf fertilizer.

Preferably, the borax water solution comprises 0.2-0.6% by mass of borax.

The invention also provides a jackfruit anti-cracking fruit foliar fertilizer, wherein the foliar fertilizer comprises borax, calcium chloride, ammonium molybdate and water.

Preferably, the mass percentage of borax in the foliar fertilizer is 0.2-0.6%, the mass percentage of calcium chloride is 0.05-0.25%, and the mass percentage of ammonium molybdate is 0.01-0.03%.

The invention also provides a pineapple honey anti-cracking method based on the application of the technical scheme or the foliar fertilizer of the technical scheme, which comprises the following steps: and spraying the foliar fertilizer every 8-12 days in the young fruit period after pollination.

Preferably, the spraying times are 2-3 times.

Preferably, the spraying amount of each spraying is to be sprayed to the leaves to drip water.

The invention provides application of a borax water solution as a jackfruit anti-cracking fruit leaf fertilizer. After the foliar fertilizer disclosed by the invention is used, the fruit cracking rate is reduced from 90% to 3%, a high-efficiency fruit cracking prevention effect is realized, and the foliar fertilizer has no any phytotoxicity on jackfruit.

fig. 3 is a diagram of the effect of preventing pineapple from cracking after the foliar fertilizer of the invention is sprayed in the embodiment 1 of the invention.

Detailed Description

In the invention, the borax water solution comprises 0.2-0.6% by mass of borax. In the invention, the mass percentage of the borax is preferably 0.3-0.5%, and most preferably 0.4%. The source of the borax is not particularly limited in the invention, and a conventional borax commercial product well known to those skilled in the art can be adopted. In the invention, the borax is used for supplementing boron for growth of jackfruit, reinforcing cell walls and preventing jackfruit from cracking, and when the concentration of the borax is higher than the protection range, leaves of fruit trees can be fallen to cause phytotoxicity.

The invention also provides a jackfruit anti-cracking fruit foliar fertilizer, wherein the foliar fertilizer comprises borax, calcium chloride, ammonium molybdate and water. In the invention, the mass percentage of borax in the foliar fertilizer is 0.2-0.6%, the mass percentage of calcium chloride is 0.05-0.25%, and the mass percentage of ammonium molybdate is 0.01-0.03%. In the invention, the mass percentage of the borax is preferably 0.3-0.6%, and most preferably 0.4%; the mass percentage content of the calcium chloride is preferably 0.08-0.15%, and most preferably 0.1%; the mass percentage content of the ammonium molybdate is more preferably 0.02%. In the present invention, the calcium chloride is used for supplementing calcium element, and the ammonium molybdate is used for supplementing molybdenum element, so as to provide a material base for reinforcing cell walls. The preparation method of the foliar fertilizer is not specially limited, and the solute and the solvent are mixed by adopting a conventional method.

The invention also provides a pineapple honey anti-cracking method based on the application of the technical scheme and the foliar fertilizer of the technical scheme, which comprises the following steps: and spraying the foliar fertilizer in the young fruit period after pollination is completed. In the invention, the foliar fertilizer is preferably sprayed every 8-12 days, and more preferably every 10 days. In the invention, the spraying frequency is 2-3 times. In the invention, the spraying amount of the spraying is to spray the spraying to the leaves and drip water.

The following describes in detail the jackfruit anti-cracking foliar fertilizer, the anti-cracking method and the application thereof according to specific embodiments, and the technical scheme of the invention includes but is not limited to the following embodiments.

Example 1

Before the foliar fertilizer is applied, the fruit cracking rate is up to 90%, and after the foliar fertilizer is sprayed, the fruit cracking rate is reduced to 3%.

FIG. 1 is a picture of early cracking of jack fruit without spraying the foliar fertilizer of the present invention; FIG. 2 is a fruit cracking diagram of the pineapple honey in the late development stage without spraying the foliar fertilizer of the invention; fig. 3 is a diagram of the fruit cracking prevention effect of the jackfruit sprayed with the foliar fertilizer.

Example 2

The fruit cracking rate of the fruit orchard is 95%, and the fruit cracking rate is reduced to 2.8% after the foliar fertilizer is applied.

Example 3

The fruit science and technology garden in the famous cities of the forest dust town of the famous state usually has jack fruit, the fruit cracking rate is 65 percent, and the fruit cracking rate is reduced to 1 percent after the foliar fertilizer is applied.

Example 4

In the fruit test field of the Yangtze goat horn of the Ministry of Maocan, the variety is often jackfruit, and the fruit cracking rate is 42 percent. After the foliar fertilizer is applied, the fruit cracking rate is reduced to 0 percent.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
