According to the characteristics of the variety, the tasting part can also be harvested according to this standard as long as it reaches the taste it should have. Sweet corn fruits could be kept fresh for 5 days at 16 ℃, but only 1-2 days at 29 ℃. At 35 ℃, the sugar content decreased significantly in about 12 hours, losing commercial value. Therefore, sweet corn after harvest must shorten the transportation time, or take the method of cooling and preservation. Sweet corn is popular with insect families because of its high sugar content. Mainly: corn borer, armyworm, beetle, thrips, aphids and so on. Stink bugs mainly occur in Sichuan during the fruit ripening period. The damage is the most serious on the ear, and the kernels of the killed corn become hard, white or yellow and underdeveloped. Most of them migrate from other corn fields.
