Adding boron fertilizer 0.5-1 kg of borax per acre, or 3.5-7 kg of boron magnesium fertilizer, mixing with appropriate amount of nitrogen and phosphate fertilizer as base fertilizer, or spraying with 0.1%-0.2% borax solution during the growth period, can increase production. 11% increase the sugar content by 0.7%.
The application of watermelon melon soaked with 300-500 times the watermelon seed, or in the watermelon seedling period, sitting period and the expansion of the watermelon with 200-300 times the spray, can increase production by about 10%, increase the sugar content of 0.7%.
Rare earth fertilizer spraying rare earth fertilizer Chang Leyi phytochemicals, can increase production by about 20%, increase sugar content of 0.6% -1.7%, foliar spray, spray three times throughout the reproductive period, the first time in the watermelon 5-6 At the leaf stage, the spraying concentration was 0.03%, and the spraying concentration was 0.06%-0.08% for the second and third time in the initial flowering period and the swelling period, respectively.
Inactivated Disposable Virus Sampling Tube
Inactivated Disposable Virus Sampling Tube is based on Hank's balanced salt solution enriched with inactivator and nucleic acid protective agents.
It is used for nucleic acid extraction of samples such as viruses,mycoplasma,chlamydia and ureaplasma. Inactivated Disposable Virus Sampling Tube is an upgrade from the Hank's solution. Additional various components,such as BSA,HEPES,amino acids,cryoprotectant,etc.,are added to enhance the virus integrity. It can be used for nucleic acid extraction of virus,mycoplasma, chlamydia and ureaplasma samples and later virus isolation. The pH of the preservation solution is 7.4±0.5. The medium contains antibiotics and antimycotics for the purpose of inhabitation of bacteria and yeasts overgrowth.
It helps to maintain the cellular integrity and preserve the viruses, mycoplasma, chlamydiae and ureaplasma.
