Technology for harvesting early-maturing mangoes in advance by 1-3 months

Abstract

The invention relates to the technical field of mango planting, and discloses a technology for harvesting early-maturing mangoes in advance by 1-3 months. The technology comprises the following stepsof 1) before foliage spraying (not more than 45 minutes), selecting agricultural foliage fertilizer-grade nitrate nitrogen-phosphorus-potassium-calcium fertilizer and spherical nano carbon sol according to the proportion of 10 parts of nitrogen, 10 parts of phosphorus, 20 parts of potassium, 10 parts of calcium and 1 part of carbon, adding 100-25 times of water, and performing uniform stirring toprepare a preparation for later use; (2) spraying the water-soluble preparation prepared in the step (1) to mango leaf surfaces by using a sprayer at 6 pm later in a proper phenological period (tip leaf maturation and stabilization) in autumn and winter (October-January); and (3) repeating the step (2) for one to two times at intervals of 7-15 days according to the mango terminal bud germination process condition and the weather condition (spraying needs to be supplemented according to the circumstances when it rains within three days of spraying). According to the technology for harvesting the early-maturing mangoes in advance by 1-3 months, the action time from preparation use to mango blooming is remarkably shortened, the cost is low, and the side effect is small.

Description

technical field [0001] The invention relates to the technical field of mango planting, in particular to a technology for harvesting early-maturing mangoes 1-3 months in advance. Background technique [0002] Mango is known as the "King of Tropical Fruits". It is loved by consumers because of its delicious taste and rich vitamins and other nutrients, but it is only produced in (sub)tropical regions; my country is the second largest mango producer in the world. Tens of millions of dollars of fresh mangoes are still imported. At present, only some areas in Hainan (Sanya, and some areas in Ledong, Dongfang, and Changjiang) can supply mangoes with the highest prices in the early season (February-April), although February-April The average purchase unit price (yuan / kg) of the origin can be 50-200% higher than the peak period [0003] The plant growth regulator paclobutrazol (soil application or foliar spray) is commonly used in mango production in Hainan early season to advance the...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides a technology for harvesting early-maturing mangoes 1-3 months in advance, which has the advantages of low cost and little side effects, and solves the problem of the widespread use of the plant growth regulator paclobutrazol (soil application or foliar spraying) to advance the flowering period and increase the flowering rate. Paclobutrazol is prone to side effects of inhibiting vegetative growth, reducing fruit sugar content, leading to premature tree senility, and decreased taste quality: Mango varies according to variety, soil, water and paclobutrazol application methods However, different amounts of paclobutrazol are needed, and it is difficult for ordinary mango growers and large-scale commercial production enterprises in my country to accurately apply paclobutrazol without its side effects, which is not conducive to the problem of comprehensive application to the growth of mangoes.
