Green watermelon ripening sweetener and application method thereof

Abstract

The invention provides a green watermelon ripening sweetener and an application method thereof. The ripening sweetener mainly comprises a biological information substance of chitosan, a plant regulator of calcium chloride, a biological bacterium agent of photosynthetic bacteria culture solution, a solubilizer acetic acid and water. The application method of the green watermelon ripening sweetener comprises the following steps: uniformly spraying the green watermelon ripening sweetener to watermelon plants in a manner of 1-10 kg per mu (a unit of area) each time; and spraying once in an efflorescence period and twice in a swelling period. With the adoption of the green watermelon ripening sweetener and the application method thereof, the mature period of watermelons is shortened, the ripeness degree is improved, the watermelons come into the market ahead of time, and the quality of the watermelons is improved; as the contents of vitamin C and soluble sugar are increased, the watermelons can be promoted to swell at the same time, thus the yield per unit area of the watermelons is increased, and the benefits of watermelon farmers and retailers are improved. The application method is simple and easy to operate and implement, is low in cost price and strong in operability, and has excellent economic and social benefits.

Description

[0001] technical field [0002] The invention belongs to the application technical field of novel plant growth regulators, and in particular relates to a green watermelon ripening-stimulating sweetener and an application method thereof. Background technique [0003] Watermelon, also known as water melon, cold melon, summer melon, is the fruit of Cucurbitaceae watermelon. Because it was introduced from the Western Regions in the Han Dynasty, it is called "watermelon". Watermelon is a traditional summer heat-quenching product in my country. Over the years, the planting area of ​​watermelon in my country has been stable at about 20 million mu, with an annual output of more than 30 billion kilograms, ranking first among all kinds of fresh fruits. From south to north, from east to west in my country, watermelons are grown in most areas. Breeding high-quality watermelon varieties with short maturity, high sugar content and high yield has always been the goal pursued by agricultu...

Problems solved by technology

Cultivating excellent watermelon varieties with short maturity, high sugar content and high yield has always been the goal pursued by agricultural experts, and it is also an urgent need for the majority of melon farmers and consumers. There are also problems of species degeneration, species decline, and yield decline.

[0004] In order to achieve early maturity, agricultural experts mainly use techniques such as mulching, greenhouse cultivation, and greenhouse cultivation to extend the growth period of watermelons forward, but this increases the production input of melon farmers; there is also a method of using ethephon to stimulate the ripening of watermelons from the outside. However, it cannot improve the quality of watermelon and increase the sugar content. The time and method of use must be s
