In recent days, in the 700-acre modern agricultural demonstration garden in Danyang City, Jiangsu Province, many watermelons have competed to burst. The cracking of watermelon has caused concern. People are worried that using an expanding agent, the watermelon will explode, and whether there is a risk of abuse of plant hormones. The fruits ripened with hormones will not be harmful to the human body. Caused public concern, watermelons in many parts of the country appear to be sluggish.
Is using hormones the only way to increase the price of watermelons?
No, in fact, the sweetness of watermelon is not the only factor that determines consumer purchase. In watermelon production, in order to improve its sweetness, the following measures can be taken:
Add organic fertilizer:
In general, the maturity of the Mushi is 2500-3000 kg of organic fertilizer and 100 kg of cooked cake fertilizer. It is applied before the ploughing of the watermelon field, and then the ploughing is performed. The organic fertilizer is preferably treated with a starter, such as a goldfish fertilizer, and fermented. After the fertilizer is efficient, improve soil structure.
Generally, Mushi 7~10kg potassium fertilizer (without nitrogen) is used as base fertilizer; in the melon period, 5kg of potash fertilizer is applied; in the initial stage of watermelon seedlings, 0.3% potassium dihydrogen phosphate is continuously sprayed twice, or deep-buried phosphate fertilizer is 25-30kg/mu. , Or cooked chicken manure and ash.
Appropriate application of boron fertilizer in the watermelon field can effectively prevent the occurrence of too thick and hollow phenomenon of watermelon rind, and it also has obvious effects of increasing production, thin skin and sweet meat. Generally 100 grams of borax per acre, first with a small amount of hot water will be dissolved in borax, then add 50 kg of fresh water, spray on the leaves of watermelon before flowering 1 or 2 times, spray once every 7-10 days, can also be poured with boron per hole Liquid 1 to 1.5 kg
Adding microbial fertilizer
Such as goldfish microbial fertilizer, mu 1-2 kg
The early use of the golden treasure biological sweetening spirit can protect flowers and fruits, prevent flowering and fruit drop, and overcome physiological and environmental obstacles such as low temperature and low light. The use of the middle and late stages can promote fruit enlargement and supplement the various trace elements required for fruit growth to prevent cracking. Increase the soluble solid content of fruit by 2%, increase the sugar content of the fruit by 0.8-1.5 degrees, and promote early coloring for 10-15 days, with deep and uniform color. At the same time can enhance the fruit hardness, extend the storage period, as long as the dilution of 500-800 times liquid foliar spray.
