1 heap compost peeling method: is China's traditional walnut peeling method. The technical point is that the fruit harvested in a timely manner to the outdoor shade or indoor, avoid exposure to the sun, and then about 50cm thickness pile into a heap (pile too thick perishable). If you add a layer of dry grass or dry leaves about 10cm thick on the fruit pile, you can increase the temperature inside the pile, promote fruit ripening, accelerate the speed of peeling. General composting 3 to 5 days, when the green fruit skin off the shell or cracked more than 50%, you can use a stick to knock off the skin. For those who have not peeled can be composted for several days until all peeled. Do not make the green skin black, or even rot when composting, so as not to contaminate the seed kernel with dirty liquid seeping into the shell, reducing the quality of nuts and commercial value.

2 agent peeling method (do not recommend this method): due to the composting peeling method peeling time is long, low efficiency, high rate of fruit contamination, the greater the impact on the quality of nut commodities, where, since the 1970s, some units began to try the vinyl ripening peeling technology, the specific practice is: after harvesting the fruits, in a concentration of 0.3% to 0.5% vinyl solution dipped in about half a minute! The specific method is: after harvesting the fruit in the concentration of 0.3% to 0.5% vinyl dip about half a minute in the solution, and then stacked in the shade or indoors at a thickness of about 50cm, at a temperature of 30 ℃, relative humidity of 80% to 95% of the conditions, after 5 days or so, the rate of peeling can be as high as 95% or more. 2 days or so can be peeled. Ethylene ripening time and the size of the concentration of drug and fruit maturity. Fruit maturity is high, the drug concentration is low, ripening period is also short.
