Skillful use of EM original dew can keep navel orange from cracking.

There is usually no ideal technique to prevent navel orange from cracking. Only by selecting good varieties, strengthening soil management, timely irrigation and scientific use of fertilizer. the application of growth regulators and other measures to reduce fruit cracking as far as possible. However, in practice, some fruit growers have found that spraying EM chlorophyll fermentation broth can prevent navel orange from cracking and solve the problem of fruit cracking for orange navel orange production. It is economical and affordable, can comprehensively promote the whole navel orange production process, improve quality, and achieve the goal of high efficiency and low consumption.

1. The formula is 100kg: 40kg of grass, 40kg of clean water, 3kg of brown sugar, 3kg of EM raw dew and 14kg of EM fermentation material.

2. The first method is to cut fresh and tender grass on the same day and find a plastic bucket with a cover that can hold 100kg. The second is to melt brown sugar in boiling water so that it is not hot, pour it into the original EM dew and let it sit for 48 hours. Third, use 400g potassium dihydrogen phosphate, dissolve in warm water and put into No. 2 Middle School. Third, the plastic piercing the bottom first sprinkles the EM mixture containing potassium dihydrogen phosphate, then cushion the grass in turn, pour into the mixture, make the liquid device in the plastic poke about 10cm away from the mouth, cover, let it ferment for more than 15 days, let the grass rot, and take the grass liquid diluted 100,150x to the fruit trees to spray. (note: small orchards can be retted with 50 kg plastic buckets in proportion.) it is better for the grass to be green and high in protein. If pine needles, bitter leaves and Xanthium leaves can be retted together, it also has the effect of disease prevention.

If the EM grass fermentation broth is used, the effect will be better if an appropriate amount of zinc sulfate (medical grade) and 0.26% calcium nitrate are added every 50 kg of water. Zinc sulfate can inhibit photorespiration during drought, calcium can sweeten and improve coloring, and can play a better role in drought resistance. If it can be used every semimonthly to January, it can also prevent abnormal fruit drop, and can promote strong fruit, improve quality and color earlier.
